Abstract

This experiment was conducted to study the effects of dietary metabolizable glucose (MG) level on performance and physiological indices of dairy cows under heat stress. Sixteen healthy Holstein cows with similar parity, days in lactation, milk yield and body weight were randomly divided into four groups with four cows in each group. Cows in test groups 1 to 4 were fed experimental diets containing 121.31, 109.70, 99.27 and 89.55 g/kg MG, respectively. The experiment lasted for 42 days, including a 14-day pre-experiment period and a 28-day experiment period. The results showed as follows: rectal temperature and respiratory rate of dairy cows (the means during whole period) reached the lowest in test groups 2 and 3, respectively, and were both significantly lower than those in the other groups (P<0.05). At different time point, feed intake and milk yield of dairy cows in test group 3 were all higher than those of the other groups, and the means during whole period were significantly higher than those in the other groups (P<0.05). Milk fat, milk protein, milk dry matter milk percentages (the means during whole period) in test group 3 were significantly higher than those in the other groups (P<0.05), and lactose percentage in test group 1 was significantly higher than that in the other groups (P<0.05). In conclusion, the change of dietary MG level can affect performance and physiological indices of dairy cows under heat stress; under conditions in the present study, the optimal level is 99.27 g/kg, which can improve feed intake and milk yield.
