商品代蛋鸡饲养管理手册WTD standardization office【WTD 5AB- WTDK 08- WTD 2C】商品代蛋鸡饲养管理手册商品蛋鸡生产性能育成期Array育雏条件从出生的育成期良在4-5周周的体重指设备及鸡舍环境控制：正大褐商品代蛋鸡育雏期各项饲养空间需求（1）：第一周时每个鸡笼另外放置一个饮水器。

（2）：确保所有的雏鸡都可以接近两个饮水乳头。

（3）：在笼底铺够维持7天的纸，每天揭去一层。

注意：-雏鸡已习惯使用新的饮水器之后，才可逐渐拿走育雏开始时使用的饮水器。

-应监测饮水量。

为了保持良好的垫料质量，应该细心地调整饮水器或饮水乳头以防饮水漏出。

-两周内应每天清洗饮水器，之后每周清洗一次。

建议的温度和相对湿度为使育雏舍内设备和垫料在雏鸡到达时达到适宜温度，建议鸡舍温度升到28—-不可忽视育雏最初几天雏鸡与垫料接触造成的热量损失。

-建议每1000天雏鸡配备2台燃气育雏器或2台1450大卡的辐射加热育雏器。

育雏舍内温度和相对温度应均匀一致。

雏鸡的分布是判断温度是否适宜的最好参照：-平养时，可根据雏鸡在每个鸡栏或整个鸡舍内的分布状况来调整舍内温度。

-如果雏鸡聚集在育成器下→温度太低。

-如果雏鸡远离热源，挤靠在鸡栏的边缘→温度太高。

采食和饮水。

之后逐渐减少光照强度，到15天时减至每日10勒克斯即可。

光照强度的调整也依赖于鸡群的行为习性。

促进生长的饲喂方案从出生到5周龄，雏鸡不能根据饲料能量水平调整采食量。

为促进采食，建议提供具有足够蛋白质及能量的破碎料，在温和气候时到28天，在炎热气候时到35天（两种情况都能使体重达标）。

下述是使育雏良好开始的几个关节点。

关节点：-雏鸡到达前打开龙头冲洗饮水系统，确保饮水器中不留有消毒剂残留。

-正确调整饮水器/乳头的高度，乳头应与小鸡的眼部水平同高，圆形饮水器放置到地板上。

-在饮水乳头下方铺纸以吸引雏鸡，往纸上或纸盘中撒一些饲料。

-检查乳头/饮水器是否足够。

蛋鸡饲养管理指导手册

蛋鸡饲养手册第一部分优质饲料的生产饲料在养鸡成本中占70—80%，所以优质的饲料是养鸡降低成本提高效益的重要保证。

饲料是用来给动物提供养分的。

要想配制出优质的饲料，首先，我们必须知道动物用于维持和生产对养分的需要量；由于养分来源于各种饲料原料，所以我们还必须知道每种原料中各种养分的含量；而更重要的是，我们必须知道动物对这些养分的利用率。

而要获得以上信息就需要现代技术研究和专门的知识，在此基础上，营养专家才能作出物美价廉的饲料配方，而没有好的质量控制和正确的饲料生产过程，再好的饲料配方也只是一张白纸。

总之，生产出优质饲料需要：科学的饲料配方，先进的技术设备和严格的质量控制。

正大饲料的先进性主要表现在配方科学、设备先进、品质优良。

1、科学的饲料配方科学的饲料配方，必须符合养殖标准的要求。

正大饲料就是根据养殖对象在不同生长时期的不同要求，以及原料的营养成份，进行合理配比并经过科学加工制成的。

因而可为全价料。

这种全价料（包括颗粒和粉料），质量稳定可靠，饲料报酬高，因而可以提高成活率，缩短饲养周期，降低生产成本，获得最佳经济效益，正大所生产的系列化畜禽饲料品质完全达到国际先进水平，并被列为中国饲料工业协会向社会公开推荐的饲料产品。

2、先进的技术设备正大集团的主要饲料生产设备是引进美国的HOUGH公司具有九十年代世界先进水平的设备和技术，全部生产过程从原料的输送、过筛、储存、粉碎、配料、打粒、冷却到包装整个工艺流程均由电脑程序控制。

电脑按预制可编程序完成配料、称重、混合等工艺流程，且具有自检功能和故障报警功能。

粉碎机喂料子流，可根据原料的不同水分自动调节流量。

采用精密度高的混合机将各种配料混合均匀。

其均匀度之变异系数为4—6，制粒机制成颗粒饲料结构密实，成份均匀。

我公司是迄今为止河北省唯一引进这套设备的生产厂家，依靠这些先进的设备，石家庄正大定能为广大养殖户生产出更为优质的饲料产品，为发展畜牧业、丰富人民的“菜篮子”做出更大的贡献。

NUTRITION MANAGEMENTGUIDE COMMERCIALSIntroductionMany years of genetic research have developed layers with excellent production traits like liveability, production and egg quality.These highly favourable genetic characteristics can only be fully realized when the bird is provided with good management, which includes, but is not limited to, good quality feed, housing and proper management practice.The purpose of this management guide is to help the producer to gain the best possible results for their investment. This will be achieved by providing conditions in which the layers can thrive. The information supplied in this publication is based on the analysis of extensive research and field results, produced over time and with many years of experience.We do recognize that over time, many egg producers have developed their own management program, based on specific housing types, climate, feed, market conditions and other factors. These individual management techniques will also be the result of experience and many of these techniques will work for our layers as well.Therefore do not hesitate to use your own experience in conjunction with the guidelines in this guide. And of course, do not hesitate to consult our distributors who will be happy to help in any way they can.Institut de Sélection Animale B.V.Villa ‘de Körver’Spoorstraat 69P.O.

It takes weeks to develop the digestive tract. During the first 8-10 weeks, any increase in the energy level is accompanied by an increase in growth. When given the feed in a crumb form, young pullets are able to increase their feed intake.The table below shows the influence of energy level and presentation method on the bodyweight of pullets at 5 weeks of age.Presentation. Dietary Energy LevelMashBodyweight at 5 weeksCrumbsBodyweight at 5 Weeks3100 kcal 375 g 412 g2790 kcal 345 g 405 gNewcombe (1985)After 10 weeks of age, pullets correctly regulate their energy intake according to the energy level of the diet in both hot and temperate climates. Under consumption during that period is often the result of a poor grit size. The objective is to develop the pullet's ability to eat feed, so that it can increase its consumption by approximately 40% in the first few weeks of lay.During the period 10 - 17 weeks, it is important to develop the digestive system by using diets with an energy concentration less than or equal to that of the layer's diet.Protein RequirementsThe amino acid requirements are to a large extent dependent on the feed conversion ratio and, therefore on age; that is why, when young the requirements expressed in mg of amino-acids per g of growth are the same as a broiler.The table below shows the influence of amino acid content on the weight of pullets at 4 weeksRation 100 % 90 %in % of the recommendations)Protein (%) 20 18Digestible Lysine (%) 1.01 0.91Digestible Methionine+Cystine (%) 0.76 0.69Weight at 4 weeks (g) 335 302Bougon1997Any delay in growth during the first few weeks will be reflected in a reduced bodyweight at 17 weeks and in later performance. It is, therefore, extremely important to use a starter diet for the first 4 or 5 weeks, which has an amino acid/protein ratio similar to that of the broiler.Any amino acid deficiency will result in a reduction in growth rate and an increase in the FCR100 % 90 % Amino Acid content of diets(in % of the recommendations)Bodyweight at 28 days (g) 335 302Bodyweight at 118 days (g) 1685 1630Feed consumption (g) 6951 6904Feed conversion ratio 4.12 4.24Bougon, 1997In hot climates, the amino acids and minerals concentrations should be slightly higher than in temperate climates. That results in a reduction in the maintenance requirement, and, therefore in the feed conversion ratio.Feed PresentationFeed consumption is determined to a large extent by the form of presentation and the stage to which the digestive tract has developed. Presenting feed in crumb form makes it easier for the chicken to eat it, reduces the time taken in eating, and encourages growth. The energy cost of eating, thus saved, gives an improvement in feed conversion ratio.Form of Dietary Presentation Mash Crumbs Difference Weight at 70 days (g) 984 1016 + 32 g Weight at 99 days (g) 1344 1405 + 61 g Weight at 123 days (g) 1589 1664 + 75 gSource: ISA/CNEVA, 1996This benefit of feeding crumbs will only be obtained when the birds have access to good quality crumbs in the feeders. A poor quality crumb can lead to a build up in fine particles in the feeders and, therefore have the opposite effect to that sought.From 0 to 4/5 weeks, we recommend using a crumbed diet, after which mash, with a good particle size, should be used.It is, however, possible to use a granular feed later, where the grinding is coarser, or even as crumbs, if need be. However, we recommend using a mash diet from 12 weeks to avoid a risk of under consumption at the beginning of the sexual maturity if the change is made later.The bird's appetite for feed depends to a large extent on its particle size. After 4 weeks, we recommend the following particle sizes:Particles below 0.5 mm: 15 % maximumParticles above 3.2 mm: 10 % maximumAt least 75 to 80 % of the particles should be between 0.5 and 3.2 mm. If this standard cannot be achieved, it is preferable to use a diet of good quality crumbs.Development of the digestive systemThe achievement of good growth and a rapid increase in feed consumption at start of lay depends on the chicken having a well-developed digestive system, especially a good strong gizzard.Using feed of good particle size, giving grit during rearing and/or using limestone granules from 10 weeks will all contribute towards good gizzard development.Between 3 and 10 weeks, we recommend that 3 g per pullet per week (particle size 2 to 3 mm) are offered. After 10 weeks this can be increased to 4 to 5 g (particle size 3 to 5 mm). It is also possible from 10 weeks onwards to use a diet 50 % of the calcium is supplied in carbonate form with a particle size of 2 - 4 mm.Feed specifications during rearing periodThose requirements are based on the “European Amino acids Table” (WPSA, 1992) of raw materials composition and expressed as digestible amino acids by using the digestibility coefficients mentioned in the “Tables de composition et de valeur nutritive des matièrespremières destinées aux animaux d’élevage” (INRA editions 2002).Between 18 & 24 °C Diet Starter Grower Pullet Pre - lay Units 0 - 4 weeks 4 - 10 weeks 10 - 16 weeks 112 days to1 - 28 days 28 - 70 days 70 - 112 days 2 % layMetabolisable energy kcal/kg 2950-2975 2850-2875 2750 2750MJ/kg12.3-12.411.9-12.011.511.5 Crude protein % 20.5 19 16 16,8Methionine % 0.52 0.45 0.33 0,40 Methionine + Cystine % 0.86 0.76 0.60 0.67Lysine % 1.16 0.98 0.74 0.80Threonine % 0.78 0.66 0.50 0.56 Tryptophan % 0.217 0.194 0.168 0.181Digestible amino acidsDig.Methionine% 0.48 0.41 0.30 0.38Dig.

There are also additional reasons which are related to the birds directly. For example, birds are very sensitive to the feed presentation and the introduction of new raw materials, for this reason we recommend a limited number of feed changes.Amino acids requirements depend of the productivity of the flocks and from the uniformity of the productivity. Our amino acids recommendations are based on an average productivity of 60 g per day. At 50 weeks, the egg mass produced is around 58 g. A lot of birds are able to produce more than 60g of egg mass over a period of 50 – 65 weeks. This is the reason why is difficult to reduce the amino acids levels after 50 weeks without affecting the productivity.A deficiency in amino acids reduces in a first time egg weight and in a second time the persistency, around 4 or 5 weeks later.Pre- lay Feed or Layer 1Medullary bone is developed in long bone before the first ovulation. The total calcium contained in this medullary is around 1.5 to 2 grammes. A pre-layer feed with a higher calcium level is needed to establish this bone reserve. It has to be used from approximately 16 weeks. Its characteristics are similar to the layer 1, but with a level of calcium of 2 – 2.2%.Don’t forget to use the Layer 1 before 2% lay. If the change is realized later, the earliest birds ingest around 1,8g of calcium and need to produce a shell with 2g of calcium. They will stop or reduce laying for some days and will produce eggs without shell. These birds will exhibit cage layer fatigue later and osteoporosis at end of lay.We think that the risk will be reduced by using a layer 1 instead of a pre-lay feed. However, if the limestone is in 2-4 mm particles form, it is possible to use the layer 1 at 16 weeks. The main reason for the use of pre-lay feed was the risk of under consumption when the limestone used was in powder form. Don’t forget to use the Layer 1 before 2% lay.Layer 1Layer 1 has to be satisfying the amino acids requirements for growth and production at a moment where the feed consumption is lower. At start of lay feed consumption is lower because the birds have not yet reached their adult body weight. Growth is not completely finished by 28 weeks. With regard to protein, a requirement for growth is added to the requirement for production.From a practical point of view, we have estimated that it is necessary to increase the concentration of amino acids by about 6 % during the 18-28 week period in relation to the feed consumption observed after 28 weeks.This feed has to be used until the moment that the feed consumption is normal or an average egg size of 60-61g is obtained or around 26-28 weeks.At the onset of lay, it is desirable to encourage feed consumption and quickly to obtain eggs of marketable size. For this, a feed enriched in fat allows to improve the presentation of diet which gives an increase in feed consumption. Oils rich in polyunsaturated fatty acids are responsible for a large increase in egg weight.Layer 2This feed has to be used from 26-28 weeks until 50 weeks or end of lay. If it is possible, it will be good to increase the limestone level at 50 weeks to reduce the percentage of seconds. Birds have daily requirements for amino-acids and minerals, consequently, the percentage of nutrients has to be defined according to the feed consumption observed. The feed consumption depends mainly of the energy requirement and of the temperatureLayer 3Amino acids requirement: Taking into account persistency in lay, individual variability and egg weight, the requirement for amino acids does not fall throughout the laying period. In an economic context, it may be worth reducing the safety margins slightly. However, the best results, in terms of productivity and feed conversion ratio, are obtained, when one maintains the intake level of amino acids. Any deficiency of amino acids, no matter, which type of amino acid, shows up as a reduction in performance, of which 2/3 is due to a reduction in rate of lay and the remaining 1/3 is a decrease in mean egg weight. It is, therefore, not possible to reduce egg weight towards the end of lay by reducing the amino acid concentration without bringing about a reduction in rate of lay.Persistency in lay has improved considerably (30 to 35 weeks above 90% lay). An analysis of the individual performance over the period 40-66 weeks shows that 66 % of the birds had performance above average. The 40 % best layers had laid 177 eggs in 182 days and /or 63.2 g of egg mass per day.Productivity of a sample of 694 pullets hatched in 2001 during the period 40-66 weeksQuintile Rate of lay Egg Mass/day1st 2nd 3rd 4th 5th 98.2 %96.3 %94.1 %90.1 %76.6 %65.0 g61.4 g59.1 g56.0 g47.8 gMean 91.0 % 57.8 g % of pullets above the mean 66.3 % 60.4 %Hendrix Genetics 2002Egg weight: A reduction of the oil percentage and energy level is a way to get a stabilization of the egg weight.Shell quality: Shell weight increases with age throughout lay.

Main conclusions are thefollowing.Between 2400 and 3000 kcal, for an energy level reduction of 100 kcal, the energy consumption drops by an average of 1.2 % when the effect of diluting the feed is studied andby 1.4% when the reduction in fat levels is studied. The energy level of the feed has little effecton the number of eggs produced, and, in all cases, the differences are less than 1%. The eggweight reduces in accordance with the reduction in the feed energy level. The reduction can beestimated at about 0.5% or 0.3g for a variation of 100 kcal. The consumption rate, expressedin kcal per gram of egg produced, always improves with the dilution of the feed. The gain isabout 0.8% for 100 kcal. This rate gain is a result of a reduction in body weight, an improvement in feather cover and an improvement in the digestibility of the feed. In manyexperiments the addition of fats seems to have a specific effect on the energy consumptiondue to an improvement in palatability and the physical form of the feed. When the feed isdiluted, the reduction in consumption is particularly marked at the time of the change. Layinghens take several weeks to increase their level of consumption gradually.Influence of the fibre level on productivityFeed dilution forces hens to increase the volume and quantity of feed ingested and, therefore,to increase the feed consumption time. There is no longer any doubt that feed dilution bringsabout an improvement in plumage and a reduction in feather picking itself. This explains themortality reduction observed in certain trials using diluted diets.Comparison between feed in meal or pellet form shows that the consumption times are lowerwhen the feed is in pellet or crumb form. This explains why feed in pellet form causesdeterioration in plumage and increases feather picking.Even though most researchers are in agreement over establishing a relationship betweenconsumption time and feather picking, some very recent studies show a specific requirementfor insoluble fibre. Indeed, it appears that there is a specific requirement for insoluble fibre. The absence of insoluble fibres in the feed is responsible for the consumption of feathers and their presence in the gizzard, even when hens are housed in individual cages. Some studies make it possible to conclude that insoluble fibres do have an effect on the quality of plumage and on mortality. The specific size of the fibres, mainly lignin, would seem to be important.We have noted that countries using sunflower meal in quite significant quantities have lower mortalities than those of countries that do not use it, whether using cages or floor systems. Very positive effects were observed after the introduction of sunflower meal to feed for free-range hens.Effect of granulometryFeed consumption is highly dependant upon granulometry. Chickens have a marked preference for grains. They are easy to pick up and do not lead to beaks becoming clogged. Ahen will always tend to leave fine particles. We (ISA, 1999) carried out the following trial: a commercial feed, of good particle size, was re-milled through a finer screen. The feeds were distributed from 19 weeks of age.Influence of feed granulometry on performance of laying hens between 23 and 51week sParticle size Standard Fine Difference in %< 0.5 mm 9 % 31 %> 3.2 mm 10 % 0 %0.5 to 3.2 mm 81 % 69 %> 1.6 mm 65 % 21 %Laying, % 93.9 90.7 - 3.4Egg weight, g 63.3 62.7 - 0.9Egg mass, g/d 59.41 56.85 - 4.3Consumption, g/d 118.1 114.2 - 3.4Consumption Index 1.989 2.008 + 0.9Weight at 33 wks (g) 1.930 1.8831999 ISA, Feed consumption is reduced by about 4 g when the feed is finely ground. This leads to a reduction of egg mass produced.Distribution of fine feed is equivalent to rationing for hens. In this experiment, the laying rate proves to be affected more than the egg weight. Sometimes in other experiments, the reverseis observed.ConclusionEnergy regulation is not specific to a breed, white egg layers or brown egg layers, but dependson the dilution methods used. The feed density (gm per litre) seems to be the limiting factor in ingestion regulation. The presence of insoluble fibre appears to be essential. It increases gizzard size, improves starch digestibility and limits feather picking by reducing the need to ingest feathers.Conversely, the addition of fats brings about an improvement in feed palatability and thus an increase in energy ingestion in proportions which can be very significant. Increase in egg weight is only one result of this. These effects are dependent upon the quantity and type of fats added.From a practical point of view, the effect of low density, high cellulose (insoluble fibre) raw materials may be balanced by the use of fats. The feed presentation also has an effect on energy consumption. Too fine feed presentation causes a reduction in energy consumption.It thus appears that the 3 following factors must be controlled: the physical form of the feed, the cellulose content and the oil content. A balance between these 3 criteria must be sought in order to make possible the expression of genetic potential at a lower cost.Principal applications and recommendationsAt the onset of laying, it is desirable to encourage feed consumption and quickly to obtain eggs of marketable size. For this, a feed enriched in fat (1.5 to 2.5 % ) and incorporating a minimum of insoluble fibre is recommended. After the onset of laying, a slightly lower energy level, richer in cellulose, will allow a good energy efficiency to be obtained (expressed in kcal) and plumage to be maintained. This strategy could be particularly beneficial for alternative production (free range, organic…), especially in the absence of ground litter.From the practical point of view, the effect of raw materials which are rich in cellulose (insoluble fibre) and of low density can be compensated by the use of fat. Feed granulometry also affects energy consumption. Particles which are too fine lead to a reduction in consumption.Amino acids requirements for commercial layersGenetic progress and nutritional consequencesJust as for the other species, genetic progress has a considerable influence on dietary amino acid concentrations. Over the last 30 years, production to a constant age has increased by more than 40 %, while feed consumption has been reduced by about 10 %. An important consequence of this genetic progress has been a change in the daily amino acid requirements. It has also called into question the practice of phase feeding, since productivity remains high over longer and longer periods. The best units nowadays have daily egg outputs of over 60g/bird right up to 52 weeks of age.The implication of genetic change in deciding amino acid levels is, therefore, considerable. It can be approached in the following way:Feed conversion ratio over the period 30-50 weeks:1971: 2.87 g of feed / g of egg1981: 2.36 g of feed / g of egg2005: 1.95 (-17%) g of feed / g of eggClassically, daily nutrient requirements have been expressed in mg / day. While this type of expression may be very easy for the formulator to use, it does not allow for genetic progress, nor for genotypic differences. Those genotypes, which produce large eggs, have larger daily requirements than those, which produce small eggs.Most Researchers agree to the expression of nutrient requirements in mg of amino acids per gramme of eggs produced. This method enables us to tackle the « requirement » starting from numerous experimental data sources. It is more precise. The synthesis that we have carried out according to this method shows it to be an excellent way of determining requirements.Ideal protein and amino acids requirementsThe concept of ideal proteins is a means of expressing the requirements for amino acids as a percentage of the requirement for LYS. There is a limited interest in applying this concept to layers. It implies that a balance between the different amino acids is necessary for optimizing requirements. That would suggest that high protein or amino acid levels would have a negative effect on performance.In fact the formulator should make a point of satisfying the requirement for the following amino acids: MET - CYS - LYS - THR - TRP - ISO and VAL. This is only valid for diets and raw materials in common usage.Those requirements, which need to be defined by comparison with reference tables, have been expressed from NRC (1994) table of raw materials composition. These results have been expressed as digestible amino acids by using the digestibility coefficients mentioned in the RPAN 1993 tables. Giving the expression in the digestible form has reduced the variability of the results observed.Recommendations for amino acids expressed in total or digestible and ideal proteins established for a production of 59.5 egg mass per day.Limiting amino acids Ideal proteinbased onNRC 1994Requirements in mg per g Daily Requirementsbased on NRC table 1994 based on NRC table 1994Dig.

By formulating in digestible Amino Acids we are better able to satisfythe requirements of the birds, to reduce the necessary safety margins and assess the raw materials according to their true biological value. Formulation according to total amino acids leads to the same nutritional value being given to all raw materials irrespective of their digestibility. That leads naturally to increasing the safety margins in order to guarantee fully meeting the requirements of the birds.Protein Requirements: When diets are formulated by taking into account the need to satisfy the requirement for each of the 7 essential amino acids, it doesn't seem to be necessary to introduce a minimal constraint for protein. The requirements for the limiting amino acids are generally enough.On the other hand, if all the essential amino acids are not taken into account when formulating,it is necessary to use a constraint for minimum protein, so as to reduce the risk of a deficiency.Limiting factors: The experience acquired during the last decades in the feeding of layers, especially the use of synthetic lysine, has enabled us to assert that ISOLEUCINE and VALINE are becoming the limiting factors in layers feeds when meat products are excluded from the feed or when they are used in formulae based on wheat.TRYPTOPHAN is the limiting factor in formulae, where the base consists of maize, soybean meal and meat products.THREONINE and still less ARGININE do not appear to be limiting in the diets used nowadays. These last two amino acids need to be studied still further.When the requirements for ISO, VAL and TRY are covered, the requirements for the other essential and non-essential amino acids are always satisfied when 300 mg of protein per gram of egg is supplied. When the feed formula takes into account the requirements ISOLEUCINE and VALINE, it is not necessary to impose a constraint for a minimum protein level.Feed consumption and formulation: The amino acid concentration of the diets, therefore, depends on:the potential of egg mass produced, which itself determines the daily requirements the daily feed consumption which determines the amino acid concentration the feed efficiency at peak of production given the amino acid concentration in dividing the requirement expressedAmino acids recommendations for commercial layersFormulation of layer's diets can be carried out by introducing ISOLEUCINE and VALINE as nutritional constraints replacing protein as a constraint. If this is not possible, we give hereafter some indications fora minimum of protein for feed containing or not Meat and Bone Meal (MBM).(1) From a practical point of view, we estimate that it is necessary to increase the concentration of amino acids by about 6 % during the 18-28 weeks period in relation to the feed consumption observed after 28 weeks. Total or digestible amino acids levels are established for a production of 59.5 g egg mass per day.。

商品代蛋鸡饲养管理手册

商品代蛋鸡饲养管理手册商品蛋鸡生产性能育成期育雏条件从出生的第一天到产出第一枚蛋是蛋鸡一生最重要的阶段，在这一时期蛋鸡的生理能发育完善。

育成期良好的生长发育会使蛋鸡产蛋期表现优秀的产蛋性能。

本章所制定的饲养管理标准和方案，已证明可使蛋鸡在产蛋期表现出优秀的生产效果。

在4-5周时造成的任何生长发育延迟，都会影响16周的体重指标，继而影响产蛋期的生产性能，特别是会降低饲养在温和气候下的鸡群的平均蛋重和推迟炎热气候下的鸡群开产。

（1）：第一周时每个鸡笼另外放置一个饮水器。

（2）：确保所有的雏鸡都可以接近两个饮水乳头。

（3）：在笼底铺够维持7天的纸，每天揭去一层。

注意：-雏鸡已习惯使用新的饮水器之后，才可逐渐拿走育雏开始时使用的饮水器。

-应监测饮水量。

为了保持良好的垫料质量，应该细心地调整饮水器或饮水乳头以防饮水漏出。

-两周内应每天清洗饮水器，之后每周清洗一次。

建议的温度和相对湿度为使育雏舍内设备和垫料在雏鸡到达时达到适宜温度，建议鸡舍温-不可忽视育雏最初几天雏鸡与垫料接触造成的热量损失。

-建议每1000天雏鸡配备2台燃气育雏器或2台1450大卡的辐射加热育雏器。

育雏舍内温度和相对温度应均匀一致。

雏鸡的分布是判断温度是否适宜的最好参照：-平养时，可根据雏鸡在每个鸡栏或整个鸡舍内的分布状况来调整舍内温度。

-如果雏鸡聚集在育成器下→温度太低。

-如果雏鸡远离热源，挤靠在鸡栏的边缘→温度太高。

促进采食和生长的光照程序的光照，以促进采食和饮水。

之后逐渐减少光照强度，到15天时减至每日10勒克斯即可。

光照强度的调整也依赖于鸡群的行为习性。

促进生长的饲喂方案从出生到5周龄，雏鸡不能根据饲料能量水平调整采食量。

为促进采食，建议提供具有足够蛋白质及能量的破碎料，在温和气候时到28天，在炎热气候时到35天（两种情况都能使体重达标）。

下述是使育雏良好开始的几个关节点。

关节点：-雏鸡到达前打开龙头冲洗饮水系统，确保饮水器中不留有消毒剂残留。

伊莎蛋鸡光照管理

伊莎蛋鸡光照管理作者：霍清合来源：《家禽科学》2017年第04期（山东益生种畜禽股份有限公司，山东烟台 265508）中图分类号：S831.4 文献标识码：C 文章编号：1673-1085（2017）04-0026-02伊莎褐由法国伊莎公司育成，属四系配套中型体重的高产褐壳蛋鸡，具有较好的抗热性能，是当前世界最优秀的高产蛋用鸡种之一，有羽色和快慢羽两个伴性基因。

伊莎褐父本两系为红褐色，母本两系均为白色，商品代雏可用羽色自别雌雄（公雏白色，母雏褐色）。

据伊莎公司的资料，商品代鸡：0～18周龄育成率97%～98%；20周龄体重1.63kg；18周开始产蛋，21周龄达50%产蛋率，24周龄母鸡进入产蛋高峰期，高峰产蛋率96%，90%以上的产蛋率能维持20～25周；90周龄入舍鸡产蛋量409个，平均蛋重62.9g，每千克蛋耗料2.1～2.2kg；产蛋期末母鸡体重1.975kg；存活率93%。

1 育雏期光照管理育雏的最初几天光照强度很重要，充足的光线可促进雏鸡活动，尽快熟悉育雏环境，很快找到饮水和饲料，促进采食。

育雏开始的几天，应给予鸡群每天22～23h、强度30～40Lx的光照，以促进采食和饮水。

之后逐渐减少光照强度，到15d时减至10Lx即可。

光照强度的调整也依赖于鸡群的行为习性。

密闭式鸡舍（穿入鸡舍的光线不超过0.5Lx），所需的光线强度很低，密闭鸡舍育成期5～10Lx光照强度足够。

伊莎蛋鸡对光照时间的变化敏感，会影响其性成熟时间。

此外，光照时间很长会影响鸡群采食量，如果前期体重不达标，可以减缓光照时间。

在育雏育成期，正确的光照程序可促进鸡群生长发育和控制鸡群性成熟。

2 育成期光照管理制定光照计划时，一定要考虑光照强度，目的不是要突破体重记录，而是使鸡的生长按增重曲线进行。

育成期光照强度的影响，应据产蛋期的情况来决定育成期的光照强度，如果鸡群将转入开放式鸡舍产蛋，育成期的光照强度至少应为40Lx，才可避免产蛋期可能发生的神经质与啄癖。
