食品评价标准
食品评价标准Food evaluation standards are an important part of ensuring the safety and quality of the food we eat. 食品评价标准是确保我们所吃食物的安全和质量的重要部分。
These standards help to establish criteria for judging the taste, freshness, and nutritional value of food products. 这些标准帮助建立评判食品口味、新鲜度和营养价值的标准。
They also play a crucial role in regulating the food industry and protecting consumers from potential harm. 它们还在监管食品行业和保护消费者免受潜在危害方面发挥着至关重要的作用。
One of the primary functions of food evaluation standards is to ensure food safety. 食品评价标准的主要功能之一是确保食品安全。
These standards help to set limits on contaminants, such as pesticides, food additives, and microbiological organisms, that may pose a risk to human health. 这些标准有助于设定对农药、食品添加剂和微生物有害物质等的限制,这些物质可能对人类健康构成风险。
By adhering to these standards, food producers can ensure that their products are safe for consumption. 遵守这些标准,食品生产商可以确保其产品适合食用。

青贮蘑菇渣的营养品质及体外发酵特性评价
近期饲料成本的上涨给肉牛养殖业带来相当大的成本压力,同时需要从其他国家进口昂贵的牧草饲料,因为向肉牛提供优质的粗饲料是生产纹理良好牛肉的办法。
因此,有必要开发一种廉价、高质量、以副产品为基础的粗饲料来源,以缓解生产上面临的粗饲料短缺问题。
我国食用菌的种植较为广泛,由此产生的工农业副产物较为丰富,如蘑菇渣。
刁清清和毛碧增(2012)报道,以蘑菇渣为基础,同时与锯末、秸秆等混合后发酵可以提高其利用价值。
但Bae等(2006)研究发现,蘑菇渣与锯末等辅料一起发酵后水分和中性洗涤纤维含量较高,粗蛋白质水平较低,因此,用其饲喂动物时应与全混合日粮一起使用,同时还应考虑其高水分带来的储存问题(Kwak等, 2008)。
由于蘑菇渣含有低水平的易发酵碳水化合物,最好在其中添加糖蜜,以刺激乳酸菌和酵母的生长(曾淑娟, 2010)。
因此,本研究以蘑菇渣为基础,同时米糠、秸秆、糖蜜和菌种一起青贮,评估蘑菇渣青贮料的营养品质、发酵特性及其与常规饲料原料的体外降解差异性。
1 材料与方法1.1 试验原料及青贮 将食品厂收集的蘑菇渣称重后,与10%锯末、10%米糠、2%糖蜜、0.5%膨润土和0.5%微生物菌剂一起混合,准备约1.5 kg的青贮蘑菇渣混合料,用两层聚乙烯袋密封(每次处理8个重复),在25℃下封存0、7、14、28 d。
在不同的封存期收集样品,并保存在-20℃以备后续分析。
1.2 体外尼龙袋试验 选择2头平均体重为632 kg左右、带有瘤胃瘘管的荷斯坦奶牛用于评估原料组的降解性及与传统水稻秸秆和大麦秸秆等粗饲料来源稻草的消化对比。
试验动物每天饲喂4 g精料、1 kg水稻秸秆、1 kg大麦秸秆黑麦草秸秆和3 kg蘑菇渣青贮饲料,以满足其维持所需的营养,试验期间自由饮水。
瘘管中尼龙袋试验使用青贮料为青贮14 d后的蘑菇渣。
尼龙袋试青贮蘑菇渣的营养品质及体外发酵特性评价李艳梅,郑丙利,葛东杰(焦作大学化工与环境工程学院,河南焦作 454000)[摘要]本文旨在评估蘑菇渣青贮料的营养品质、发酵特性及其与常规饲料原料的体外降解差异性。

The results showed that there were significantly higher crude protein and significantly lower crude fat in fresh muscle ofWP than that in CP (P< 0.05), without significant differences in the contents of moisture and crude ash between WP and CP (P > 0.05 ). Eighteen kinds of amino acids were detected in muscles of WPand CP, with higher total content of amino acids (TAA ), essential amino acids (EAA) and four kinds of delicious amino acids(DAA) in WP than those in CP (P< 0.05). The amino acid score (AAS )and chemical score (CS )revealed that the first limitingamino acid was tryptophan in two populations, with essential amino acid index (EAAI )of 75.59% in WP and 70.77% in CP. The find ings indicated that the amino acid contents in muscles of CP are lower than that ofWP, with similar evaluation of nutritional value, be ing a potential aquaculture species.Key words: Oncorhynchus masou; wild population; cultured population; amino acid composition马苏大麻哈鱼Oncorhynchus masou 是溯河10游性鱼类,主要分布在中国、朝鲜、俄罗斯和日本。
茎瘤芥核心种质资源营养品质分析及评价
中国瓜菜2021,34(3):52-58茎瘤芥(Brassica juncea var .tumida Tsen et Lee )俗称青菜头或榨菜,是十字花科芸薹属芥菜种的一个变种。
其食用器官为膨大瘤状茎,色白肥厚、质地脆嫩,富含蛋白质、糖、维生素、矿物质以及人体必需的17种氨基酸,营养丰富,既可作为鲜食蔬菜,也可加工为“榨菜”[1]。
茎瘤芥在全国种植面积约20万hm 2,其中以重庆市种植面积和加工规模最大。
2016年,整个重庆市茎瘤芥种植面积达到10.67万hm 2,榨菜全产业链综合产值约95亿元,“涪陵榨菜”品牌价值高达138亿元[2]。
然而近年来,随着茎瘤芥产业不断发展以及加工规模不断扩大,人们对其原材料的营养性和安全性提出了更高要求,同时也对高品质茎瘤芥品种的选育提出了新的课题,但在茎瘤芥育种方向上,过去主要偏茎瘤芥核心种质资源营养品质分析及评价莫言玲,刘义华,曾静,陈静静,易奥云,黄爽(长江师范学院现代农业与生物工程学院重庆涪陵408100)摘要:为筛选优质茎瘤芥资源,以7份茎瘤芥核心种质为试材,对其可溶性蛋白、可溶性糖、维生素C 、游离氨基酸、总酚、总黄酮、硝酸盐、亚硝酸盐和粗纤维等9种营养成分进行了测定和分析,并利用隶属函数法对其营养品质进行综合评价。
结果表明,7份茎瘤芥核心种质之间亚硝酸盐含量无显著差异,而其余8个品质性状含量在不同茎瘤芥种质中均有一定差异。
其中以硝酸盐、可溶性糖和总酚含量的变异系数最大,分别为24.13%、22.57%和22.54%,以粗纤维和亚硝酸盐含量的变异系数最小,仅为4.35%和8.84%。
通过隶属函数法分析可知,综合营养品质最佳的种质是SJYS 和PFB12-18-23-10,平均隶属函数值均大于0.7,可作为亲本材料用于杂交育种以选育优质高产茎瘤芥新品种。

2,菜心已在全国范围销售并出口港澳㊁东南亚㊁日本㊁美国㊁欧洲[2]㊂钟玉娟等[3]研究菜薹硝酸盐积累与品种㊁营养品质之间的关系发现,红菜薹㊁白菜薹㊁绿菜薹不同品种间的硝酸盐含量有显著差异,其中红菜薹和部分白菜薹属于高营养品质和低硝酸盐含量的一组,绿菜薹大部分是属于高硝酸盐含量和低营养品质的一组㊂相关性分析和PCA 分析表明,硝酸盐的积累与维生素C㊁可溶性固形物㊁还原糖和蛋白质的积累存在显著相关,降低硝酸盐含量将可能改善蔬菜的营养品质㊂卢宇鹏等[4]研究不同熟性菜心品质性状的多样性分析发现,10个品质性状的变异系数均在11.17%~42.76%,变异系数最大的品质性状是叶柄长,为42.76%,变异系数最小的品质性状是叶绿素含量,为11.17%;而在早㊁中㊁晚3种不同熟型的菜心材料中,中熟类型菜心不仅硝酸盐含量低,而且外观品质也最符合优质菜心商品性状的要求;除叶绿素含量㊁叶形和硝酸盐含量外,早熟类型菜心的开展度㊁最大叶长㊁叶宽㊁叶柄长㊁薹高㊁薹粗㊁可溶性蛋白含量7个指标均显著小于晚熟类型㊂梁春红等[5]研究硒营养对菜心影响发现,适量浓度的硒可以显著促进菜薹的膨大增加粗度,从而提高产量,且硒能明显降低菜心叶的硝酸盐含量,提高叶的类胡萝卜素含量㊁游离氨基酸含量和维生素C 含量㊂该研究对收集到的15个菜心品种维生素C㊁可溶性固形物㊁还原糖㊁蛋白质㊁粗纤维进行分析和评价,结果表明菜心品种间各营养成分含量差异明显,可以为选择优质品种在生产上推广应用奠定理论基础㊂笔者对除试验数据的单一营养指标进行常规分析外,同时综合品质分析采用平均隶属函数法和主成分分析法来进行综合品质分析评价,期望能找出单一营养成分最佳的菜心品种和综合品质较好的菜心品种,为推广优质菜心品种奠定理论基础㊂1㊀材料与方法1.1㊀试验材料㊀供试材料包括15个菜心品种,这些品种均为生产上大面积推广和应用的品种㊂2021年秋季在广东省农业科学院蔬菜研究所白云基地种植,在商品成熟期取样测定分析其营养品质指标㊂1.2㊀试验方法1.2.1㊀样品制备㊂菜心商品期收获后,将其(包括嫩茎叶安徽农业科学,J.Anhui

营养监测(nutritional surveillance): 是指连续观察某特定人群的营养状况及其 产生这种营养状况的原因的活动。包括收 集分析对居民营养状况有制约作用的因素 和条件,预测居民营养状况在可预见的将 来可能发生的动态变化趋势等。
营养状况测定与评价
要想身体健康, 必须做到合理营养
怎样吃才算合理营养呢? 那就要学会科学搭配食物
如何知道膳食搭配是否科学呢? 这就需要通过营养状况评价来检验
军人营养状况评价的重要性

消费者保健计划评估调查英语
消费者保健计划评估调查英语Consumer Health Plan Evaluation SurveyIntroductionHealthcare is one of the most important sectors that affect the quality of life of individuals. However, not all healthcare plans are created equal, and consumers need to choose the best plan for their needs. In this survey, we aim to evaluate the satisfaction of consumers with their health plans and identify areas for improvement.MethodologyThe survey was conducted online, and participants were recruited using social media platforms and email. The survey consisted of 26 questions divided into three sections: demographics, health plan evaluation, and suggestions for improvement. The survey was anonymous, and participants were assured of the confidentiality of their responses.ResultsDemographicsA total of 500 consumers participated in the survey, with 250 males and 250 females. The age range of participants was between 18 and 65 years, with the majority falling between 25 and 45 years. The participants were from different regions of the country, with the highest percentage coming from urban areas.Health Plan EvaluationThe health plan evaluation section consisted of 16 questions that aimed to evaluate the satisfaction of consumers with their health plans. The questions covered various aspects of health plans, including coverage, cost, access to care, and quality of care.CoverageThe majority of participants (80%) reported that their health plan covered the services they needed. However, 20% reported that their plan did not cover some services they needed, such as mental health services.CostThe cost of healthcare is a major concern for consumers, and the survey results showed that 60% of participants weresatisfied with the cost of their health plan. However, 40% reported that the cost of their health plan was too high, and they struggled to pay for it.Access to CareAccess to care is another important aspect of health plans, and the survey results showed that 70% of participants were satisfied with their access to care. However, 30% reported that they had difficulty accessing care, either because of long waiting times or because they had to travel long distances to access care.Quality of CareThe quality of care is perhaps the most important aspect of health plans, and the survey results showed that 75% of participants were satisfied with the quality of care they received. However, 25% reported that they were notsatisfied with the quality of care, either because they received poor quality care or because they did not receive the care they needed.Suggestions for ImprovementThe suggestions for improvement section consisted of 10 questions that aimed to gather suggestions from consumers on how health plans can be improved. The questions covered various aspects of health plans, including coverage, cost, access to care, and quality of care.CoverageThe majority of participants (70%) suggested that health plans should cover more services, particularly mental health services, dental services, and vision care.CostThe majority of participants (60%) suggested that health plans should be more affordable, either by reducing the cost of premiums or by reducing the cost of services.Access to CareThe majority of participants (70%) suggested that health plans should improve access to care, either by reducing waiting times or by increasing the number of providers.Quality of CareThe majority of participants (75%) suggested that health plans should improve the quality of care, either byincreasing the number of providers or by improving the training of providers.ConclusionIn conclusion, the survey results showed that consumers are generally satisfied with their health plans, but there are areas for improvement. Consumers want health plans to cover more services, be more affordable, improve access to care, and improve the quality of care. Health plans should take these suggestions into account when designing their plans to ensure that they meet the needs of consumers.。

Evaluation of nutritional quality of moringa (Moringa oleifera Lam.)leaves as an alternative protein source for Nile tilapia(Oreochromis niloticus L.)Nahid Richter,Perumal Siddhuraju,Klaus Becker *Department of Aquaculture Systems and Animal Nutrition,Institute for Animal Production in the Tropics and Subtropics,University of Hohenheim,D-70593,Stuttgart,Germany Received 17June 2002;received in revised form 9September 2002;accepted 9September 2002AbstractThis study was conducted to evaluate the suitability of freeze-dried moringa leaf meal,Moringa oleifera ,as an alternative protein source for Nile tilapia.Three experimental diets were formulated to contain moringa leaf meal at levels of 10%,20%and 30%of the total dietary protein (Diets 2,3and 4,respectively)and one diet acting as a control (Diet 1)which included only fish meal and wheat meal as protein sources.All diets were isonitrogenous (35%crude protein)and isoenergetic (20kJ g À1).A 7-week feeding trial was carried out on triplicate groups of seven fish (9–11g)in 45-l aquaria connected to a recirculating system.The daily fish ration was calculated at 15-g feed per metabolic body weight (kg 0.8)per day (about five times maintenance).No feed-related mortality was observed during the whole experimental period.Diets with higher inclusion levels of moringa leaves (Diets 3and 4)significantly depressed growth performance of the fish (SGR:2.0%in both groups)compared to Diets 1and 2(SGR: 2.7%and 2.4%,respectively).The relatively high total phenolics (0.7%and 1%),nonhaemolytic saponin (1.5%and 2.3%)and phytic acid (0.5%and 0.8%)in Diets 3and 4,respectively,as well as NDF (3.8%and 5.7%)and ADF (3.0%and 4.5%)in the aforementioned diets may have contributed to the poorer growth performance in these groups.These

significant reduction in growth.D 2003Elsevier Science B.V .All rights reserved.Keywords:Nile tilapia;Moringa oleifera ;Protein replacement;Antinutrients1.IntroductionAquaculture is the fastest growing sector of world human food production and has an annual increase of about 10%(FAO,1997).To sustain such a high rate of growth,a matching increase in fish feed production is imperative (Francis et al.,2001a).On the other hand,the high cost and fluctuating quality of fish meal as well as its uncertain availability (Alceste,2000)have led to the need to identify alternative protein sources for fish feeds.Considerable emphasis has been focused on the use of conventional plant protein sources,such as soybean (Jackson et al.,1982;Sadiku and Jauncey,1995),groundnut (Jackson et al.,1982),cottonseed (Jackson et al.,1982;El-Sayed,1990)and rapeseed meal (Jackson et al.,1982).However,their scarcity and competition from other sectors for such conven-tional crops for livestock and human consumption as well as industrial use make their costs too high and put them far beyond the reach of fish farmers or producers of aquafeeds (Fasakin et al.,1999).Therefore,in order to attain a more economically sustainable,environmentally friendly and viable production,research interest has been directed towards the evaluation and use of unconventional protein sources,particularly from plant products such as seeds,leaves and other agricultural by-products (Olvera-Novoa et al.,1988;El-Sayed,1999;Siddhuraju and Becker,2001).Ogino et al.(1978)showed that the inclusion of a protein concentrate derived from rye grass leaves of up to 43%of total protein for common carp and 40%for rainbow trout,respectively,had beneficial effects on the growth performance as compared to a control diet.The use of leaf protein concentrate as a potential dietary feed ingredient has also been evaluated with regard to tropical and subtropical plant leaves.Olvera-Novoa et al.(1990)showed that 35%replacement of fish meal with purified alfalfa protein concentrate had no adverse effect on Mossambique tilapia.Successful replacement of 25%processed (soaked)Leucaena leaf meal has also been reported for Nile tilapia (Wang and Wee,1987).However,only limited information is available on the utilisation prospects of foliages directly as alternative or additional protein sources as fish feed.Moringa oleifera Lam.,a member of the family Moringaceae,is a fast-growing plant widely available in the tropics and subtropics with great economic importance for the food and medical industry (Becker and Makkar,1999;Foidl et al.,2001).The seeds are a rich oil and protein source and can also be used for the purification of water.The roots are a source of spices.The leaves are rich in carotenoids,ascorbic acid and iron (Siddhuraju and Becker,unpublished data).Although the leaves and pods are widely recognised as a food source for humans and a dry season feed for animals (Makkar and Becker,1997),there is no information regarding the utilisation of moringa leaves in fish feed.Therefore,the present study was carried out to evaluate the suitability of moringa leaves as a partial protein replacement for fish meal (10%,20%and 30%replacement ofN.Richter et al./Aquaculture 217(2003)599–611600N.Richter et al./Aquaculture217(2003)599–611601 total dietary protein)in practical diets for Nile tilapia based on its effects on growth performance and body composition.2.Materials and methods2.1.Experimental setup and fishA group of210Nile tilapia(Oreochromis niloticus)fingerlings(8–13g)reared at the University of Go¨ttingen(Germany)were transferred to Hohenheim University,and kept in 200-l tanks to be acclimatised.They were fed at around maintenance energy requirement with a standard diet containing approximately40%protein,10%lipid,10%ash and a gross energy content of20kJ gÀ1dry matter.After1week,84fish were randomly selected and divided into12groups of seven fish(9–11g),each of which were stocked in 1245-l aquaria at27F1j C.The aquaria were integrated into a recirculatory system.The system was subjected to a photoperiod of12-h light/12-h dark.Water quality was monitored during the experiment and DO and pH fluctuated between7.0F1.1and 7.3F0.8mg lÀ1,respectively.Water flow was adjusted to keep the oxygen saturation above80%.The12groups of seven fish were randomly assigned to four treatments,one for each experimental diet,so that there were three replicate groups per treatment.The fish were starved for2days before the start of experiment,while during the experimental period,the fish were fed at15-g feed per metabolic body weight(kg0.8)per day(around five times their maintenance energy requirement)in five equal installments using an automatic feeder.Fish were weighed individually at the beginning and end of the experiment,but weighed in bulk at weekly intervals to adjust the feeding level for the subsequent week.No feed was given on the weighing days.Before starting the experi-ments,10fish of the same population were killed and analysed for initial body composition.At the end of seventh week,fish were weighed,sacrificed and analysed for whole body composition and hepatosomatic index.Prior to the chemical analyses,both the initial and experimental groups of fish were autoclaved at121j C for30min, homogenised and freeze-dried.2.2.Diet formulationThe M.oleifera leaves,obtained from Niger where they were freshly harvested and immediately freeze-dried on site,were finely ground in a laboratory mill and stored at À18j C before feed formulation and analysis.Fish meal and wheat meal were obtained from Kurt Becker,Bremen,Germany and the experimental station of the Universita¨t Hohenheim,Reutlingen,Germany,respectively.Prior to feed formulation,the proximate composition and amino acid analysis of moringa leaves,wheat meal and fish meal were determined(Table1).Four isonitrogenous and isoenergetic diets were formulated to include35%total dietary protein.Freeze-dried moringa leaves were included in the diets at levels of12%,24%and36%to replace10%,20%and30%of total dietary protein and were designated as Diets2,3and4,respectively(Table2).A diet which contained no moringa leaves served as the control(Diet1).2.3.Biochemical analysesThe proximate analyses of diet ingredients,diets and whole bodies of fish (CP,CL,CF and ash)were based on the procedures of the AOAC (1990)standard methods.Moisture content was measured by putting samples in an oven for 24h at 105j C.Fibre constituents such as neutral detergent (NDF)and acid detergent (ADF)fibres of moringa leaves were determined according to the procedure described by van Soest et al.(1991).Gross energy was measured by bomb calorimetry (IKA-calorimeter C7000)using benzoic acid as a standard.An automated amino acid analyser (LKB 4151,Alpha-plus,LKB-Biochrome,UK)was used to determine the amino acid composition of feed ingredients.The samples were hydrolysed for 24h with 6M HCl at 110j C and the sulfur-containing amino acids were oxidised using performic acid before acid hydrolysis.The tryptophan content of feedingredients was determined by the method of Pinte´r-Szaka ´cs and Molna ´r-Perl (1990).The total phenolics,tannins and condensed tannins were determined by the spectrophotometric methods described by Makkar et al.(1993).Phytic acid estimation was carried out by the modified photometric procedure of Vaintraub and Lapteva (1988).Trypsin inhibitor activityTable 1Proximate

(1993)reference protein and were comparable to those of other plant-based proteins (Table 3).The leaves were found to contain about 0.53%tannins and only trace levels of condensed tannins,but a substantial concentration of total phenolics (2.74%)was measured.Nonhaemolytic saponins (6.38%,as diosgenin equivalents)and phytic acid (2.25%)were also detected in the leaves.However,no activity of the potent antinutrient trypsin inhibitor was found.Thus,by increasing moringa leaf content in feeds,crude lipid and fibre as well as NDF and ADF,ash and total phenolics,saponin and phytic acid were increased.3.2.Feed intake,growth performance and feed utilisationFish in dietary Groups 1and 2fed actively on the experimental diets throughout the experiment,while Groups 3and 4were slightly reluctant to consume the feed when this was presented,particularly in Week 1.There was no feed-related mortality observed during the entire period of the experiment (49days).The growth performance of tilapia fed with different diets is shown,for the entire experimental period,in Fig.1.The overall performance is summarised in Table 4together with the nutrient utilisation.A significant (P <0.05)reduction in the FBW and %BWG of Groups 3and 4when compared to fish fed with the control diet (Group 1)was observed,but compared to Group 2,this difference was not statistically significant.This was also the case with the FCR in which an increasing trend was observed with increasing moringa leaf content,but only the value found in fish fed with Diets 3and 4differed significantly from fish fed with the control diet.The SGR and PER were found to be similar in Diets 1and 2and those valueswereFig.1.Growth performance of fish fed experimental diets.N.Richter et al./Aquaculture 217(2003)599–611605significantly higher than those of fish fed with Diets 3and 4.When compared to the control diet (1),significantly lower FI,PPV ,ER and ANLU were observed in fish fed with all other diets.3.3.Whole body compositionThe whole body composition of fish at the beginning and at the end of the experiment are given in Table 5,while Table 6shows the chemical composition of the weight gain of fish fed with different diets.By increasing the inclusion level of moringa leaves in diets,body moisture increased,while on the other hand,lipid and gross energy values decreased significantly (P <0.05).The crude protein and crude ash content remained constant in all experimental groups.Although the higher inclusion of moringa leaf meal in the diets significantly reduced the hepatosomatic index (HSI),the lower inclusion level (Diet 2)did not influence the HSI value as compared to those of fish fed with control diet.Table 5Whole body proximate composition (%fresh weight basis)at the

initial value over the experimental period,the CCG highlighted a disproportionally low net lipid gain in these fish.The net gain included the same proportion of protein in all groups,while the contribution of ash declined with increasing dietary moringa content.4.DiscussionThe results obtained in the present study show that the performance of the fish fed with higher levels of moringa(20%and30%of protein base)was inferior to those of fish fed with the control diet(Diet1)and the diet containing10%moringa leaf meal (Diet2).The significantly higher FCR value in Diets3and4was obviously the result of poor feed intake of this group of fish during the first week of the experiment while adapting to the new diet.The depression of growth performance and growth parameters could likely be attributed to several factors,among which the presence of antinutrients will have been important.A high level of saponins(1.5%and2.3%in Diets3and4, respectively),total phenolics(0.7%and1.0%in Diets3and4,respectively)and phytic acid(0.5%and0.8%in Diets3and4,respectively)could be the main factors causing growth retardation.Saponins,which are found in many of the potential alternative plant-derived feed sources,are considered to have a detrimental effect on fish.It has been reported that saponins in lupin seed meal(1.1%)and alfalfa(<0.30%in low saponin varieties to>1.5%in high saponin varieties)impaired the growth performance of rainbow trout(de la Higuera et al.,1988)and tilapia(Olvera-Novoa et al.,1990;Yousif et al.,1994).The negative effect of saponins might be because of their well-known effect as a surface-active component on the biological membrane by which the permeability of the intestinal mucosal cells is increased and the active nutrient transport hindered(Johnson et al.,1986),even though at low dietary levels(150mg kgÀ1),they have been shown to increase growth in tilapia(Francis et al.,2001b).Phytate,on the other hand,can reduce the bioavailability of minerals,reduce the protein digestibility by the formation of phytic acid–protein complexes and damage the pyloric caecum by depressing the absorption of nutrients(Francis et al.,2001a).It has been reported that 5–6g of phytic acid per kilogram diet can impair the growth of rainbow trout(Spinelli et al.,1983)and common carp(Hossain and Jauncey,1993).The level of phytic acid in our experiment for the fish fed with Diets3and4was0.5%and0.8%,respectively. With respect to total phenolics,Al-Owafeir(1999)showed growth reduction in tilapiawhen fish were fed with low levels (0.27%)of tannic acid.On the other hand,Becker and Makkar (1999)reported that 2%inclusion of quebracho tannins (condensed tannins)were shown to be tolerated without any adverse effect on growth,whereas similar levels of hydrolysable tannins (tannic acid)reduced the feed acceptability after 4weeks of feeding.A relatively higher concentration of total phenolics from mucuna beans (<0.72%)in common carp diet has also been shown to significantly reduce the growth performance and feed utilisation in common carp (Siddhuraju and Becker,2001).The presence of higher concentrations of total phenolic substances is known to reduce the protein digestibility and amino acid availability through phenolics–protein and/or phenolics–protein–enzyme complexes.A further possible reason for low growth at high moringa inclusion levels might be the levels of cell wall constituents (NDF and ADF)in Diets 3and 4.Although the NDF (3.8%and 5.7%)and ADF (3.0%and 4.5%)content of Diets 3and 4are in the acceptable range based on the literature,the combination of aforementioned antinutrients with fibre could have caused the significant decreases in PPV ,ANLU and ER in Diets 3and 4.Anderson et al.(1984)showed drastic reduction in growth,PER,FCE and whole body fat of Nile tilapia when more than 10%a -cellulose was included in the diet.Hilton et al.(1983)also reported a similar reduction in growth performance of rainbow trout when fed with a high fibre diet.Shiau et al.(1988)observed a significant decrease in lipid content of Nile tilapia fed diets containing 6%,10%and 14%of carboxymethyl cellulose (CMC)as compared to those fed 2%CMC.Hilton et al.(1983)mentioned that this phenomenon was associated with a decrease in gut passage time and diet digestibility.Furthermore,Shiau (1997)reported the importance of nutrient absorption dependency on the time for which nutrients are in contact with the absorptive epithelium.Dietary fibre apparently influences the movement of nutrients along the gastrointestinal tract and significantly affects nutrient absorption.Another exacerbating effect might be a change in enzyme activity,possibly through adsorption or immobilization of enzymes by dietary fibre.It has also been shown that fibre can bind nutrients like fat,protein (Shah et al.,1982;Ward and Reichert,1986)and minerals (Ward and Reichert,1986),and reduce their bioavailability.It is likely that the higher concentrations of CL in the diets at increasing levels of moringa inclusion did not contribute towards dietary digestible energy since CL in moringa will probably have contained a considerable amount of indigestible waxes and cutins.On the whole,a higher level of moringa inclusion would therefore probably have reduced the energy available needed for protein synthesis and led to lower growth performance and nutrient utilisation.Nevertheless,it should be stressed that even at high levels of moringa inclusion (Diet 4),the CCG values for lipid were positive.By definition,negative values are possible even when the fish are gaining weight,which would indicate that energy for the deposition of other tissues must come at least partly from the body lipid available at the start of the trial.These results show that even Diet 4,although resulting in a leaner fish,was of sufficiently high quality for the fish not to have to fall back on its energy reserves for protein deposition.The level of whole body moisture was also significantly higher in Groups 2,3and 4compared to the control group.This agrees with the results of Siddhuraju and Becker (2001)who reported a similar reduction in whole body lipid and energy content ofN.Richter et al./Aquaculture 217(2003)599–611608N.Richter et al./Aquaculture217(2003)599–611609 common carp and increasing moisture after feeding diets with plant-based proteins,in their cases derived from mucuna.Shearer(1994)also observed that the body moisture is inversely related to body lipid.The hepatosomatic index was also significantly lower in fish fed with Diets3and4.This might be explained by a reduced deposition of fat in these groups which obviously affected the size of the liver.The results of our preliminary study on nutritional quality of raw moringa leaves as partial feed for fish indicate that up to10%inclusion of this material can be recommended for Nile tilapia.In view of the favourable amino acid profile of moringa leaves and their wide and ready availability throughout the tropics and subtropics,moringa can be considered as a potential feed component with high nutritive value for fish.However, more investigations must be done for finding feasible and simple methods for inactivating/ reducing the antinutritional factors for inclusion of moringa leaves in practical diet for tilapia at higher levels.AcknowledgementsN.Richter
