【摘要】 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1 080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软件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=(6 750.7 W0.75-69.2)△W+10.96 W0.75二期:MEI=(221.4-2 020.1 W0.75)△W+3.89 W0.75三期:MEI=(122.4-572.1 W0.75)△W+3.53 W0.75更多还原

【Abstract】 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)△W+10.96 W^0.75In the 2^nd period: MEI=(221.4-2 020.1 W^0.75)△W+3.89 W^0.75In the 3^rd period: MEI=(122.4-572.1 W^0.75)△W+3.53 W^0.75更多还原
