摘要

本试验旨在研究畜舍添加喷淋和风扇处理对夏季泌乳驴基础生理指标、血清生化指标及激素指标的影响,为泌乳驴夏季福利化管理提供理论依据。选取24头年龄[(7.15±0.69)岁]、产后时间[(51.95±2.24) d]、体重[(249.41±17.24) kg]相近的泌乳驴,分为4组,每组6个重复,每个重复1头驴。4组分别为对照组(CON组)、喷淋组(SG组)、风扇组(FG组)、喷淋+风扇组(SFG组),试验期28 d。在试验期间,每天11:00—17:00,FG组和SFG组开启风扇,SG组和SFG组每隔1 h进行1次喷淋,每次喷淋2 min。结果表明:在试验期14:00时,与CON组相比,SG组和SFG组母驴头部表皮温度显著降低(P<0.05),FG组母驴头部、耳部、腿部表皮温度均显著降低(P<0.05),FG组和SFG组母驴的直肠温度显著降低(P<0.05),试验各组母驴呼吸频率均显著降低(P<0.05);与CON组相比,FG组和SFG组母驴血清中谷草转氨酶(AST)、乳酸脱氢酶(LDH)的活性显著降低(P<0.05),试验各组母驴血清中肌酐(CRE)的含量均显著降低(P<0.05);与CON组相比,FG组和SFG组的母驴血清中三碘甲腺原氨酸(T3)、甲状腺素(T4)、胰岛素(INS)、促肾上腺皮质激素(ACTH)含量显著升高(P<0.05)。综上所述,夏季高温季节在驴舍中添加喷淋和风扇能够降低泌乳驴体温,减少呼吸频率,缓解高温环境对泌乳驴血清生化指标的影响,且影响了其血清激素指标的含量,其中风扇效果相对较好。

Abstract

The purpose of this experiment was to investigate the effects of spray and fan on basic physiological indexes, serum biochemical indexes and hormone indexes of lactating donkeys in summer, and provide a theoretical basis for the welfare management of lactating donkeys. Twenty-four lactating donkeys with similar age[(7.15±0.69)-year-old], parturition time[(51.95±2.24) d], and body weight[(249.41±17.24) kg], were randomly divided into 4 groups with 6 replicates, and 1 donkey for each replicate. The four groups were the control group (CON group), spray group (SG group), fan group (FG group), and spray+fan group (SFG group), respectively. The test period was 28 days, during the experiment, the fans were working in the SFG and the FG groups from 11:00 to 17:00 every day. During this period, the SG and the SFG groups were sprayed once 1 h, spraying for 2 min each time. The results showed as follows:compared with the CON group, the head skin temperature of the female donkeys at 14:00 in the SG and SFG groups significantly reduced (P<0.05), the skin temperature of the head, ears and legs of the female donkeys in the FG group significantly reduced (P<0.05),the rectal temperature of the female donkeys in the FG and SFG groups significantly decreased (P<0.05), the respiration rate of the female donkeys in the test groups significantly decreased (P<0.05); the activities of aspartate aminotransferase (AST), lactate dehydrogenase (LDH) in serum of the female donkeys in the FG and the SFG groups significantly decreased (P<0.05), the contents of creatinine (CRE) in serum of the female donkeys in the three test groups significantly decreased (P<0.05); the content of triiodothyronine (T3), thyroxin (T4), insulin (INS), adrenocorticotropic hormone (ACTH) in serum of the female donkeys in the FG and the SFG groups significantly increased (P<0.05). Adding spray and fan to the donkey house can reduce the body temperature of lactating female donkeys, decrease respiratory frequency and relieve the effects of high temperature environment on serum biochemical indicators of lactating donkeys, and affect the serum hormone index content. Among them, the fan has better influence.
