| 摘 要： | 本文系重复测定白来航产蛋母鸡的能量需要,通过14只212—500日龄产蛋鸡的饲养试验与比较屠宰试验,求得每鸡每日的MEM、MEE与MEF的代谢能值,分别为194千卡,70.4千卡与1.5千卡,应用家畜营养学的析因法求得每鸡每日MET为266千卡。根据每鸡每日风干日粮采食量(RI)96.4克,即可将MET被RI除,求得每公斤风干日粮的MED等于2759千卡(产蛋率62％)。采用以上数据,即可制定母鸡不同产蛋率的代谢能需要量。本报告所得结果与第一次白来航产蛋母鸡能量需要量报告近似。

A Study on the Energy Requirement of White Leghorn Hen |
| |
| Abstract: | This is the second report of the energy requirement of white Leghorn hen. Through the feeding method of 14 laying hen from 212-500 days of age and throngh the Comparative Slaughter method, MEM, MEE and MEF of each hen of each day were obtained as follows. 194 kcal,70.4 kcal and 1.5 kcal respectively.By the factorial analysis method, MET/day/hen being the sum of MEM, MEE and MEF was found to be 266 kcal.MED/kg of ration was obtained by dividing MET by RI and the result was equal to 2759 kcal ( laying rate 62% ) , when RI was 96.4 gin/day.From the above data, the energy requirement of white Leghorn hen of different laying rate determined was quite similar to the result of the first report of the energy requiement of white Leghorn hen. |
