Advantages and Disadvantages of Increasing Lean 1% (55% to 56%) 增加1%瘦肉率（55%到56%）的优劣势对比
Advantages-优势 • Higher price---¥20 • 售价------增加¥20 • Better FE-------¥8 • 料肉比-增加￥8元收益 Total Adv----------¥28/pig

Whiteshire Hamroc Genetic Plan to Improve
（2007-至今） 华特希尔今后育种专注点的调整
• A renewed focus to reduce backfat and improve pounds of lean gain in all breeds • 以更新的育种观点来降低背膘厚同时提高所有品种的瘦肉率 • We changed the Herdsman MLI to double the emphasis placed on backfat and pounds of lean while maintaining improvement in sow productivity traits • 调整herdsman软件MLI计算公式中背膘厚与瘦肉量的加权比重。 （即生长性状的加权比重为繁殖性状的2倍） • We performance test maternal barrows to include more genetic variation in BF and Lean for better selection opportunities • 我们通过测量更多的母系种猪后代阉猪比例以更好的收集与校 正母系种猪的背膘厚与瘦肉率,以便于后备猪更好的选留 • Focus on the genetic traits that affect the “Profit Drivers” • 关注于重要的经济性状 相关联育种性状选育
– Robustness and High Percentage Full Value Pigs – 更低的淘汰率（群体强健），提供更高比例的全价值猪
• Maternal York and Landrace • 母系种猪，我们最优！（长白、大白）

Value of Increased Lean 进一步提高瘦肉率带来的影响
• • • • • • • • • • • In USA the acceptable standard is 53-55% lean 美国的标准是53-55% Above 55%, premiums are minimal 超过55%，带来的额外收益是微乎其微的 Below 53%, discounts get more severe 低于53%，售价会受到影响 Vast majority of pigs are acceptable (53-55%) 绝大多数的猪只是可以接受的 Many slaughter plants now pay on Carcass Weight = 75-77.5% 大部分屠宰场接受的屠宰率范围是75-77.5%左右 1% leaner carcass yields about .85Kg more carcass to sell or 20 RMB return to producer. • 提高1%的瘦肉率将额外增加0.85kg的屠宰重即增值20元人民币
