Abstract

This experiment was conducted to study the effects of heat stress on performance and the concentrations of serum hormones and heat shock protein 70 (HSP70) of dairy cows at different lactation stages. Eighteen dairy cows with similiar parity at different lactation stages (early, mid-and late lactation stages) were used in a two factors (3×2) fully crossed design with six cows per stage; two heat stress stages (heat stress stage and non-heat stress stage) were also designed. The results showed as follows: the milk yield (P<0.05) and the dry matter intake (P<0.01) of dairy cows were significantly decreased by heat stress. Compared with non-heat stress stage, the concentrations of insulin, glucagon, T4 and leptin in serum tended to be decreased under heat stress (P>0.05), and the concentrations of T3, cort and prolactin in serum were extremely significantly decreased (P<0.01), while the serum HSP70 concentration was extremely significantly increased (P<0.01). In conclusion, heat stress has serious effects on the concentrations of serum hormone and HSP70, and thus affects the performance of dairy cows; compared with mid-and late lactation stages, the effects of heat stress on early lactation are the most serious.
