Abstract

This experiment was conducted to study the effects of different proportions of fermented mulberry leaves on serum biochemical, antioxidant and immune indexes of Xiangxi yellow cattle×Limousin hybrid F1 fattening bulls (Xiangxi hybrid fattening yellow cattle). Twenty 12 to 15-month-old health Xiangxi hybrid fattening yellow cattle with similar body weight of (244.25±12.32) kg were randomly divided into 4 groups with 5 replicates in each group and 1 cattle in each replicate. Cattle in 4 groups were fed diets supplemented wtih 0 (CG group), 10% (LG group), 20% (MG group), and 30% (HG group) fermented mulberry leaves, respectively. The pre-experimental period lasted for 10 days, and the experimental period lasted for 60 days. The results showed as follows: 1) the dry matter feed intake of HG group was significantly higher than that of CG, LG and MG groups (P<0.05), and the average daily gain of HG and LG groups was significantly higher than that of CG and MG groups (P<0.05). 2) The serum glucose (GLU) content on day 60 of MG group was significantly lower than that of CG group (P<0.05), and the serum total cholesterol (TCHO) content on days 30 and 60 of MG group was significantly lower than that of CG and HG group (P<0.05), the serum very low density lipoprotein (VLDL) content on day 30 of CG group was significantly higher than that of HG group (P<0.05), the serum low density lipoprotein (LDL) content on day 60 of MG and HG groups was significantly lower than that of LG group (P<0.05), and the serum high density lipoprotein (HDL) content on day 60 of LG and HG groups was significantly lower than that of CG group (P<0.05). 3) The serum malondialdehyde (MDA) content on day 30 of HG group was significantly lower than that of CG group (P<0.05), and the serum catalase (CAT) activity on day 60 of LG and HG groups was significantly higher than that of MG group (P<0.05). 4) The serum complement 3 (C3) content on day 30 of LG group was significantly lower than that of CG group (P<0.05). In conclusion, dietary fermented mulberry leaves can improve the growth of Xiangxi hybrid fattening yellow cattle, decrease the contents of GLU, TCHO and MDA, thus regulate the functions of blood glucose, blood lipid and antioxidant of animals.
