- Abstract
To study the effects of sodium butyrate supplementation in milk on growth performance, blood biochemical indexes and health status of lactating Holstein calves. A total of 80 healthy Holstein calves were selected and divided into 4 treatment groups according to the principle of similar gender, age and body weight, namely: control group ( without sodium butyrate ), 4.4 g group, 8.8 g group, 17.6 g group. Sodium butyrate was added to milk in each group according to the corresponding dose, and the test time was 6 weeks. The results showed that: ① the average daily feed intake (ADFI) and average daily gain (ADG) of 8.8 g group were significantly higher than those of the control group (P<0.05). ② The body length index of 17.6 g group was sig‐ nificantly higher than that of control group (P< 0.05); the chest circumference index of 8.8 g and 17.6 g groups was significantly higher than that of the control group (P<0.05). ③ The GLU concentration was significantly higher in the 8.8 g group than the control group (P<0.05); the AST activity with 4.4 g was significantly higher than control group (P< 0.05); the ALP activity in the 8.8 g and 17.6 g groups was significantly higher than control group (P< 0.05). ④ The GHRH level in 17.6 g group was significantly lower than that in 8.8 g and control group (P<0.05); the SST level in the 8.8 g group was lower than the control group (P<0.05); the GLP-2 levels in 4.4 g, 8.8 g and 17.6 g groups were significantly higher than control group (P<0.05). ⑤ GSH-Px activ‐ ity in 17.6 g group was significantly higher than that in control group (P<0.05), and T-AOC content in 4.4 g group was significantly lower than that in control group (P<0.05). ⑥ IgG content in 4.4 g and 8.8 g groups was significantly lower than that in control group (P<0.05); the IgM content in 8.8 g group was significantly lower than that in control group (P<0.05). The content of IL-1β in 17.6 g group was significantly lower than that in control group (P<0.05). The content of IL-2 in 8.8 g and 17.6 g groups was significantly lower than that in control group (P<0.05). ⑦ The scores of ears and nose in the experimental group were significantly lower than those in the control group (P<0.05). The fecal score of 8.8 g group was significantly lower than that of control group (P<0.05). In summary, the addition of sodium butyrate to milk can improve the growth performance, antioxidant function and body immunity of calves, and im‐ prove the health status of calves, and the addition of 8.8 g/d is the best.
