Effects of Aerobic Exercise on Growth Performance,Blood Biochemical Indicators and Hair Physical Properties of Tan Lambs from Beach Breed
摘要
Abstract
In order to study the effects of aerobic exercise on growth performance,blood biochemical indi-cators,blood immune indexes and wool physical and chemical properties of Tan lamb.The experi-ment selected 60 female sheep that were born in 2017,had given birth to 2 offspring,and had undergone synchronized estrus and synchronized conception treatment.They were randomly divided into the experimental group and the con-trol group,with 30 ewes in each group.The ewes in the experimental group exercised for 4-6 km daily,while the ewes in the control group were raised in a closed system.The growth performance,blood bio-chemical,blood immune,and antioxidant indicators of the lambs were measured using conventional methods and enzyme-linked immunosorbent assay(ELISA)after birth and at the age of 30 d of the second growth period.The wool physical properties of the lambs during the second growth period were determined using an electron microscope and ELISA.The results showed that compared with the control group,the weight of the lambs in the experimental group at the second growth period was significantly reduced(P<0.05).Compared with the control group,the elongation rate of the wool of the lambs in the experimental group at the second growth period was significantly increased(P<0.05).Compared with the control group,the wool fibers of the lambs in the experimental group during the second growth period had better integrity,higher density,and smaller spacing.Compared with the control group during the second growth period,the levels of interleukin 2,interleukin 5,interleukin 12,interleukin 6,endothelin,and thromboxane B2 in the lambs of the experi-mental group were significantly lower(P<0.05).Compared with the control group at the birth stage,the levels of interleukin 2,interleukin 6,interleukin 12,alkaline phosphatase,albumin,blood glucose,total cho-lesterol,triacylglycerol,high-density lipoprotein cholesterol,and low-density lipoprotein cholesterol in the control group during the second growth period were significantly higher(P<0.05),and the activity of glutathi-one peroxidase was significantly lower(P<0.05).Compared with the experimental group at the birth stage,the level of interleukin 3 in the experimental group during the second growth period was extremely signifi-cantly lower(P<0.01).The levels of alkaline phosphatase,blood glucose,total cholesterol,triacylglycerol,high-density lipoprotein cholesterol,and low-density lipoprotein cholesterol were significantly higher(P<0.05),and the uric acid content was significantly lower(P<0.05).Compared with the control group at the birth stage,the uric acid content in the experimental group at the birth stage was significantly higher(P<0.05).Thus,the ewes engage in aerobic exercise for 4-6 kilometers every day,the supplementary feeding for the lambs can improve the physical and chemical properties of their wool during the second growth period,reduce the content of serum pro-inflammatory factors,lower the inflammatory response of the body,and improve the health level of the body.关键词
