Effects of different levels of Chinese herbal additives on growth performance of Liaoning Cashmere goats lactating lambs
摘要
Abstract
The experiment aimed to investigate the effects of different levels of Chinese herbal additives on the growth performance,serum biochemical indicators,and diarrhea condition of lactating lambs,in order to screen for the appropriate addition level.A total of 48 healthy male lactating lambs with an aged 23 days and a body weight of(6.59±0.03)kg were selected and divided into four groups using a single-factor randomized block design,with three replicates per group and four lambs per replicate.The control group was fed with a basic concentrate,while the experimental groups were fed with concentrate feed containing 0.1％(group 1),0.3％(group 2),and 0.5％(group 3)Chinese herbal additives,respectively.The trial period was 37 days,with a preliminary trial period of 7 days and a formal trial period of 30 days.The results indicated that compared to the control group,group 1,and group 2,the weight of lambs in the group 3 was extremely increased at 45 and 60 days of age(P＜0.01),and the average daily weight gain was extremely increased from 30 to 60 days of age(P＜0.01).Compared to the control group,the weight of lambs in the group 2 was extremely increased at 60 days of age(P＜0.01),and the feed-to-gain ratio was extremely decreased for the groups 2 and 3 from 30 to 60 days of age(P＜0.01).Compared to the control group,the levels of serum glucose(GLU),insulin(INS),total cholesterol(TC),triglycerides(TG),and total protein(TP)in lambs from the group 3 were extremely increased(P＜0.01),the albumin(ALB)content was significantly increased(P＜0.05),glucagon(PG)content was extremely decreased(P＜0.01),and non-esterified fatty acids(NEFA)content was significantly decreased(P＜0.05).The TP content in lambs from the group 2 was significantly increased(P＜0.05).The levels of β-hydroxybutyrate(β-HB)and blood urea nitrogen(BUN)in lambs from the groups 2 and 3 were significantly decreased(P＜0.05),and uric acid(UA)content was extremely decreased(P＜0.01).Compared to the control group,the diarrhea rate was extremely decreased(P＜0.01),and the recovery rate was extremely increased(P＜0.01),with a significant decrease in recovery time(P＜0.01)for lambs in the groups 2 and 3.Studies show that the addition of Chinese herbal additives to lactating lamb concentrate can improve the growth performance of lambs,enhance the metabolism synthesis of nutrients,prevent and control the occurrence of diarrhea and accelerate the recovery of diarrhea in lambs,and the addition amount of 0.5％is the best effect.关键词
