摘要
对贵州牧草种籽繁殖场饲养的萨能奶山羊的初情期、初配年龄、发情周期、发情持续期、发情季节、妊娠期、产羔率、羔羊公母比例等八项繁殖性能指标进行观察测定,并与西北农业大学的萨能奶山羊进行比较分析,从而看出在贵州饲养的奶山羊具有明显的早熟性。
Observed and determined such 8 indexes of reproductive performances of Sannens raised in forage seed production farm of Guizhou Province as the initial estrus, ages of intial mating, estrus cycles, estrus duration, estrus seasons, pregnancy duration, lambing percentage, ration between male and female baby goats, and also compared with those of Sannens in Northwestern Agricultural University. It can be seen from this that Sannens raised in Guizhou province have had an apparent early maturity.
