Abstract:

In order to evaluate the metabolic capacity and disease resistance of three main meat sheep breeds in Jilin Province, the blood physiological and biochemical indexes of Qianhua mutton Merino sheep, Black-head Suffolk sheep and Small Tail Han sheep raised in Jilin Province were measured and compared. The results showed that the blood physiological indexes of the three sheep breeds were different. The blood physiological indexes such as MID%, GRAN, GRAN%, RBC, HCT, MCH, MCHC, PLT, PDW, and PCT of Qianhua mutton Merino sheep were significantly higher than those of Black-headed Suffolk sheep and Small Tailed Han sheep (P<0.05). The WBC index value of Small Tail Han sheep was the highest, followed by that of Qianhua mutton Merino sheep, and then that of Black-head Suffolk, and there were significant differences between the breeds (P<0.05). The index value of LYM in the blood of Small Tail Han sheep was significantly higher than that of the other two breeds. MID, HGB and MCV index values in blood of Black-headed Suffolk sheep were significantly higher than those of Qianhua mutton Merino sheep (P<0.05), and the above indexes of the latter were significantly higher than those of Small-tailed Han sheep (P<0.05). However, the index values of RDW-SD, RDW-CV, MPV and P-LCR were not significantly different among the three breeds (P>0.05). The sequence of the values of 7 biochemical indicators, including ALB, TP, TBIL, PHOS, GLU, CREA, and GLO of the three breeds, from high to low was as follows: Qianhua mutton Merino sheep> Black-headed Suffolk sheep> Small-tailed Han sheep, and there were differences between the breeds (P<0.05). BUN, CHOL, AMYL, ALT, ALK and other biochemical indexes had obvious differences among the breeds (P<0.05), and Black-head Suffolk sheep had the highest BUN, followed by Qianhua mutton Merino sheep, and Small Tail Han sheep had the lowest. CHOL of Small Tail Han sheep was the highest, followed by that of Black-head Suffolk sheep, and Qianhua mutton Merino sheep had the lowest CHOL. AMYL of Black-head Suffolk sheep was the highest, followed by that of Qianhua mutton Merino sheep, and the lowest was found in Small Tail Han sheep. The index value of ALT was the highest in Qianhua mutton Merino sheep, followed by that of Small Tail Han sheep, and then that of Suffolk sheep. ALK of Black-headed Suffolk sheep was the highest, followed by that of Qianhua mutton Merino sheep, and then that of Small-tailed Han sheep. This study provides theoretical reference for the feeding management, breeding improvement, disease monitoring and environmental adaptability enhancement of the three breeds.
