鲁禽3号麻鸡能量需要研究

Study on the Energy Requirement of the Type 3 of Luqin Broiler

为了研究鲁禽3号麻鸡的最佳能量需要，选用1日龄健康雏鸡1080只，公母各1／2，随机分成9组，按不同营养水平饲喂，每组3个重复，每个重复公、母鸡各20只。试验分为一期（0～5周龄）、二期（6～10周龄）和三期（11～13周龄）3个试验期，利用SPSS软什对试验结果进行差异性分析。回归分析结果表明，在本研究条件下，鲁禽3号麻鸡能量需要量（MEI）可按下式估算：一期：MEI=（6750．7W^0.76-69．2）△W＋10．96W^0.75二期：MEI=（221．4—2020．1W^0.75）△W＋3．89W^0.75三期：MEI=（122．4—572．1W^0.75）△W＋3．53W^0.

To study the energy requirement of the type 3 of Luqin broiler, 1 080 one-day old broilers were divided into 9 groups with 60 male and 60 female broilers of each group respectively. The study was divided into 3 periods, the 1st one lasted first 5 weeks, the 2nd one lasted second 5 weeks, and the 3rd one lasted 3 weeks. The difference analysis was taken for the result by SPSS. The results indicated that the ME intake （MEI） can be calculated as follows： In the 1^st period： MEI = （6 750.7 W^0.75 - 69.2）ΔW＋ 10.96 W^0.75 In the 2^nd period： MEI = （221.4- 2 020.1 W^0.75）ΔW ＋ 3.89 W^0.75 In the 3^td period： MEI= （122.4- 572.1 W^0.76）ΔW ＋ 3.53 W^0.75 [Chinese Journal of Animal Nutrition, 2006,18 （4） ： 228- 232 ]
