摘要
本研究用１５头生长期西农莎能奶山羊（平均日龄为１３４．５±５．７天。平均体重为１８．７±１．０５ｋｇ，随机分为５组，分别按自由采食，０．８９８６，０．７１８９和０．５３９１ＭＪＭＥ／ｋｇＷ０·７５等４个能量采会水平进行两期饲养试验。饲养试验期初和期末分别进行两期比较屠宰试验，测定不同能量采食水平组生长奶山羊的沉积净能，以及研究影响生长期莎能奶山羊沉积能的因素。结果表明，生长期莎能奶山羊每公斤代谢体重沉积能与体重大小无关，其主要影响因素是能量和干物质采食量。另外，生长奶山羊的沉积能与日增重呈极显著正相关。
growing Xinong Sannen dairy goats(mean day age was 134. 5+ 5. 7d, mean weight was 18. 7 ± 1. 05kg) were used to divided into 5 groups and fed with four different energy. level(at libitim, 0. 8986, 0. 7189 and 0. 5391 MJ ME / kgW0.75 ) .to conduct two term feeding experiment . At the start and the end of feeding experiment , comparative slaughter experi- ment was carried out to determine the retentioned energy of the goats fed with different energy intake . Results shown that the retentioned energy was significantly effected by dry matter and energy intakes and it is not relative to weight of the goats.
