藏羊在江淮地区异地育肥的生长性能及生理生化指标的研究
Growth Performance and Physiological and Biochemical Indexes of Tibetan Sheep Fattening in Different Places in Jianghuai Area
摘要
Abstract
The paper was to explore the adaptability and short-term fattening effect of Tibetan sheep when raised in southern agricultural areas during winter.A total of five Tibetan rams,five Tibetan Capri-corn sheep,and five Tibetan ewes were introduced from high-altitude pastoral areas to the Jianghuai region for off-site breeding during winter.Their body weight,physiological parameters,and serum biochemical indexes were measured at different time intervals after introduction.The results showed that the growth indicators showed a positive trend in daily weight gain during the fattening period.Specifically,from 0 to 80 days after introduction,the daily gain of Capricorn sheep was significantly higher than that of rams(P＜0.05),while there was no significant difference between rams and ewes(P＞0.05).At days 1 and 5 post-introduction,Capricorn sheep exhibited the lowest heart rate(P＜0.05),while no significant differ-ences were observed among treatment groups at other time points(P＞0.05).The respiratory rate showed no significant difference among treatment groups at all time points(P＞0.05).The body temperature of rams at 10,20,55 and 80 d after introduction was significantly higher than that at 1 d(P＜0.05).There were no significant differences between ewe and Capricorn at each time point(P＞0.05),but the body temperature,respiratory rate and heart rate of Tibetan sheep introduced into Jianghuai area remained with-in normal ranges.There were no significant differences in blood physiological indexes and serum biochemi-cal among all treatment groups(P＞0.05).In summary,the effect of breeding Tibetan sheep in different places in Jianghuai area is remarkable,and the low altitude climate has no adverse effect on the health of Tibetan sheep.关键词
