Effects of Artemisia ordosica on Growth Performance,Apparent Nutrient Digestibility and Serum Biochemical Indicators of Cold-Stressed Lambs
摘要
Abstract
This experiment aimed to investigate the effects of Artemisia ordosica supplementation on growth performance,apparent nutrient digestibility and serum biochemical indicators of cold-stressed lambs.Twelve healthy 5-month-old male lambs(Australian white×small-tailed Han sheep)with similar body weight[(27.13±1.14)kg]were randomly allocated into two groups:the control group and the Artemisia ordosica group,with 6 lambs per group.The control group was fed a basal diet,while the Artemisia ordosica group re-ceived a diet where 3%of alfalfa hay was replaced by an equal amount of Artemisia ordosica.The adaptation period lasted for 7 days,followed by a 28-day trial period.The results showed that:1)no significant differ-ences were observed between Artemisia ordosica group and control group in average daily feed intake,average daily gain,feed-to-gain ratio,as well as apparent nutrient digestibility(P＞0.05).2)Only the kidney index of lambs in the Artemisia ordosica group was significantly higher than that in control group(P＜0.05),with no significant changes in the liver,spleen,pancreas and heart indices(P＞0.05).3)On day 14 of the trial,ser-um contents of urea,total protein,albumin,total cholesterol and leptin were significantly or extremely signifi-cantly increased in the Artemisia ordosica group compared with the control group(P＜0.05 or P＜0.01),and high-density lipoprotein cholesterol showed a tendency to increase(P=0.092).On day 28 of the trial,the ser-um total protein and leptin contents in the Artemisia ordosica group remained significantly higher than those in the control group(P＜0.05),while the serum albumin content was extremely significantly decreased(P＜0.01),and a decreasing trend was observed in low-density lipoprotein-cholesterol content(P=0.071);more-over,a significant positive correlation was identified between liver index and serum total cholesterol content(P＜0.05).In summary,under the conditions of this experiment,dietary supplementation with 3%Artemisia ordosica does not significantly improve the growth performance or nutrient apparent digestibility of lambs.However,it positively influences the kidney index and serum contents of total protein,albumin,total choles-terol and leptin.These findings suggest that Artemisia ordosica may have potential application in alleviating cold stress of lambs.[Chinese Journal of Animal Nutrition,2026,38(4):2782-2792]关键词
