长途运输应激对西门塔尔牛体重、血液生化指标和细胞因子含量的影响
Effects of Long-distance Transportation Stress on the Body Weight,Blood Biochemical Indexes and Cytokine Contents of Simmental Cattle
摘要
Abstract
In order to investigate the effects of long-distance transportation stress on body weight, blood biochemical indexes and cytokine contents of Simmental cattle.12 head of(292.1 ± 38.2)kg average body weight of Simmental cattle were transported for 36 h and 1 450 km at 30 ℃ of maxi-mum air temperature by open-topped truck.Blood samples from jugular vein were collected for the determination of the blood biochemical indexes and body weight was measured before and after transportation.The results showed as follows:① The body weight of Simmental cattle was ex-tremely significantly decreased from 292.1 kg to 262.8 kg after transport for 36 h and 1 450 km (P<0.01),of which the lossing was 10.03% of the original body weight.②Transportation stress significantly increased the serum cortisol level(P<0.05),extremely significantly elevated the se-rum glucose level(P<0.01),and they was decreased to the original level at 7 to 14 d after trans-portation.But transportation stress did not significantly affect the blood cholesterol level(P>0.05).③Transportation stress extremely significantly increased the serum C-reactive protein con-tent(P<0.01).The contents of serum IL-6,IFN-γ and TNF-α were significantly increased after transportation(P<0.05),and they was decreased to the original level at 7 to 14 d after transpor-tation.But the content of IL-1β in serum was not significantly affected(P>0.05).In conclusion, long-distance transportation could significantly decrease the body weight and inhibit the body im-mune function of Simmental cattle.It was necessary for Simmental cattle to have the recovery pe-riod of 14 days after long-distance transportation.关键词
