摘要:

本研究旨在开展不同杂交组合绵羊生长性能、血液生化指标和瘤胃发酵的比较研究,挑选健康且出生日期相近的湖羊×湖羊后代(HH)、杜泊羊×湖羊杂交F1代(DH)、澳洲白×湖羊杂交F1代(AH)和夏洛莱羊×湖羊杂交F1代(XH)公母羔羊各10只,测定不同品种绵羊的生长性能、血液生化指标和瘤胃发酵参数。结果表明: 1)HH组母羊的产羔率高于杂交组母羊,而杂交羊羔羊断奶成活率则高于HH羔羊。2)品种主效应分析发现,AH、DH和XH羔羊的1、30、90、180和360日龄体重以及30~90日龄、1~90日龄、1~180日龄和1~360日龄平均日增重均显著高于HH羊(P<0.01)。性别主效应分析发现,公羊90、180和360日龄体重以及除180~360日龄外的平均日增重均显著高于母羊(P<0.01)。品种与性别互作分析发现,AH羊1日龄体重显著高于其他品种羊(P<0.05),180日龄DH和AH公母羊的体重均显著高于HH公母羊(P<0.05)。3)品种主效应分析发现,AH和DH羊30~360日龄的体高以及90、180日龄的体长均显著高于HH和XH羊(P<0.01),而30日龄的体长则相反;HH羊1~360日龄胸围和管围显著低于杂交羊(P<0.01)。性别主效应分析发现,公羊180日龄体长、体高、胸围和管围均显著高于母羊(P<0.01)。4)性别主效应分析发现,公羊的血清总胆固醇(TC)含量显著高于母羊(P<0.05);品种和性别互作分析发现,HH公羊和AH母羊的血清谷丙转氨酶(ALT)含量显著高于其他羊(P<0.01)。品种主效应分析发现,HH羊白蛋白(ALB)、总蛋白(TP)和肌酐(CRE)含量显著低于其他品种羊(P<0.01),其中XH羊血清中含量最高。XH羊血清的尿素氮(BUN)和高密度脂蛋白(HDL)含量显著高于HH羊,而谷草转氨酶(AST)含量则显著低于DH羊(P<0.05)。XH和HH羊血清血糖(GLU)含量显著高于AH和DH羊(P<0.01),其他指标各品种羊之间无显著差异(P>0.05)。5)品种为主效应时分析发现,DH和XH羊乙酸、丁酸、戊酸、总挥发性脂肪酸和氨态氮含量均显著高于HH羊(P<0.05);XH羊异戊酸含量显著高于DH和AH羊,而戊酸含量则相反(P<0.01)。品种与性别互作分析发现,XH母羊异丁酸和异戊酸含量显著高于AH和DH母羊(P<0.05)。综上所述,在本试验中湖羊与澳洲白、杜泊羊和夏洛莱羊杂交后母羊的产羔率有所下降,但杂交羊羔羊成活率有所提高;杂交羊的生长发育优于纯种湖羊,这可能与其瘤胃发酵提升有关。

Abstract:

This research compared the growth rate, blood biochemical indexes and rumen fermentation of hybrid sheep from different breed combinations. Ten healthy male and ten healthy female lambs with similar birth dates from offspring of Hu×Hu sheep (HH), Dorper×Hu sheep F1 generation (DH), Australian White×Hu sheep F1 generation (AH), and Charolais×Hu sheep F1 generation (XH) were selected, and their growth rate, blood biochemical indexes and rumen fermentation parameters measured. It was found that: 1) The lambing rate of ewes in the HH group was higher than that of ewes in other groups, while the weaning survival rate of hybrid lambs was higher than that of HH lambs. 2) Analysis of breed data revealed that the body weights of AH, DH and XH sheep at the age of 1, 30, 90, 180, and 360 days, as well as the average daily weight gains for the period 30 to 90 d, 1 to 9 days, 1 to 180 days and 1 to 360 days were significantly higher than those of HH sheep (P<0.01) while the body weight of AH sheep at the age of 1 day was significantly higher than that of other breeds (P<0.05). Analysis by gender showed that the body weight of male lambs at the age of 90, 180 and 360 days, as well as the average daily gain except for the period from 180 to 360 days were significantly higher than those of female lambs (P<0.01), and the body weights of DH and AH rams and ewes at the age of 180 days were significantly higher than that of HH rams and ewes (P<0.05). 3) Body height of AH and DH sheep from the age of 30 to 360 days and the body length at the age of 90 and 180 days were significantly higher than those of HH and XH sheep (P<0.01), while the body length at the age of 30 days was the opposite. Meanwhile, the chest circumference and tube circumference of HH sheep from the age of 1 to 360 days were significantly lower than those of hybrid sheep (P<0.01). With respect to gender differences in these traits, the body length, body height, chest circumference and tube circumference of rams at the age of 180 days were significantly higher than those of ewes (P<0.01). 4) With respect to gender differences in blood biochemistry, the total cholesterol (TC) content of serum in rams was significantly higher than that in ewes (P<0.05). Analysis of the interaction between breed and gender revealed that the alanine aminotransferase (ALT) content of serum in HH rams and AH ewes was significantly higher than that in other hybrid sheep (P<0.01). Analysis of breed effects on blood biochemistry indicated that the contents of serum albumin (ALB), total protein (TP) and creatinine (CRE) in HH sheep were significantly lower than those in other sheep breeds (P<0.01), and their contents in XH sheep were the highest. The contents of serum urea nitrogen (BUN) and high-density lipoprotein (HDL) in XH sheep were significantly higher than those in HH sheep, while the content of aspartate aminotransferase (AST) in XH sheep was significantly lower than that in DH sheep (P<0.05). The serum blood glucose (GLU) content of XH and HH sheep was significantly higher than that of AH and DH sheep (P<0.01), while there were no significant differences in other indicators among different breeds of sheep (P>0.05). 5) Analysis of breed effects on rumen fermentation parameters revealed that the contents of acetic acid, butyric acid, valeric acid, total volatile fatty acids and ammonia nitrogen in DH and XH sheep were significantly higher than those in HH sheep (P<0.05). The rumen isovaleric acid content in XH sheep was significantly higher than that in DH and AH sheep, while the result for valeric acid content was the opposite (P<0.01). With respect to the interaction between breed and gender, the contents of isobutyric acid and isovaleric acid in XH ewes were significantly higher than those in AH and DH ewes (P<0.05). In conclusion, the lambing rate of ewes was decreased after Hu sheep were crossbred with Australian White, Dorper and Charolais sheep, while the survival rate of hybrid lambs was increased in this experiment. The growth and development of hybrid sheep was superior to purebred Hu sheep, which may be related to promotion of rumen fermentation.
