Study on the changes in postpartum blood biochemical and antioxidant indexes in Tan sheep
The experiment aimed to assess the postpartum health status of Tan sheep in a specific grazing area by studying the changes in blood biochemical and antioxidant indexes.Ten healthy Tan sheep with consistent body condition,weight,and gestation period were selected.Blood samples were collected from the ewes at 0th,7th,14th,and 21th days postpartum,and blood biochemical and antioxidant indexes were measured.The results showed that on the 0th days postpartum,the concentrations of total protein(TP),globulin(GLB),calcium(Ca),phosphorus(P),magnesium(Mg),and non-esterified fatty acids(NEFA)in the blood were significantly lower than those in other periods(P<0.05),while insulin(INS)and insulin-like growth factor-1(IGF-1)levels were significantly higher than those in other periods(P<0.05).On the 14th and 21th days postpartum,blood urea(UREA)concentration and total antioxidant capacity(T-AOC)were significantly lower than those in other periods(P<0.05).At 21th days postpartum,blood leptin(LEP)concentrations and superoxide dismutase(SOD)activity were significantly lower than those in other periods(P<0.05),and malondialdehyde(MDA)concentrations was significantly higher than those in other periods(P<0.05).The study indicates that the blood NEFA content increased on the 7th days postpartum,indicating that Tan sheep were in an energy deficit state,and antioxidant levels decreased.
