【Abstract】 Four feeding group of Macheng black goats (including male hornless goats, male angulate female hornless goats, female angulate goats) were taken into this contrast feeding experiment to determine the goats’ grow capability and body condition. With SPSS software we compared the weight gain per day and economic benefit in different groups. The result showed that hornless goats had better performance in some aspects, such as feed transform ratio, diseases resistance, than angulate goats; female goats had better performance than male ones in daily weight gain, feed transform ratio, diseases resistance, et al. The hornless goats were better than angulate ones and female was better than male ones in economic benefit.更多还原
