Abstract: [Objective]This study was conducted to investigate the effects of drinking water temperature （18-20℃） and feeding soybean milk daily on fattening of north Tibet female sheep and female goats. [Methods]A total of 350 two-to three-year-old culled north Tibet female sheep with similar weight were chosen and randomly divided into 7 groups （50 for each group）. During the experimental period, 50 free-grazing female sheep in control group were grazed according to the habits of farmers and herders, and no extra night supplementary feeding was made. The female sheep in 6 experimental groups were grazed according to the habits of farmers and herders in daytime and extra night supplementary feeding was made. The supplementary amount of pelleted concentrate was 280 g/d, and the sheep were allowed to intake green hay of oats freely. The pre-experimental period was 7 days and the formal experimental period lasted 49 days. At the beginning and end of the experiment, all of the experimental sheep were weighted. The animals selection, grouping, supplementary feeding schedules, experimental period and evaluation indicator in goats experiment were the same with sheep experiment. At the end of the experiment, 11 experimental animals were chosen and slaughtered from control group and experimental group in sheep experiment and goats experiment, respectively, and the slaughter rate were subsequently determined. [Results]Under the same drinking situation, there were significant differences in weight and slaughter rate with the increase of intake amount of 10%soybean milk （P〈0.05）;in the experimental groups with the same intake amount of 10% soybean milk, there were significant differences in weight and slaughter rate between the warm water drinking group and ice water drinking group （P〈0.01）. Regardless of the labor engagement and electricity charge, there were significant differences in economic benefit between different groups of fattening north Tibet female sheep （P 〈0.01）. The group 4, 5 and 6 in sheep experiment produced economic benefit and it was increased with the increase of drinking water temperature and intake amount of soybean milk （P〈0.01）, the economic benefit of 105.95 Yuan was produced by each sheep in group 6;there were significant differences in economic benefit between different groups of fattening north Tibet female goats （P〈0.01）, and economic benefit of 21.35 Yuan was produced by each goat in group 6. [Conclusion] There is still much room for improvement of weight and slaughter rate of north Tibet female sheep and goats. Applying an appropriate feeding mode for short-term fattening of north Tibet female sheep and goats can bring huge economic benefit. The results of this study provide technical references for the short-term fattening of female sheep and goats in north Tibet where feed and forage were relatively deficient.
