Abstract

Objective: This study aimed to assess the impact of different rearing site zones with varying temperature-humidity index (THI) on the metabolic regulation of lactating local dairy cows.

Materials and methods: Forty local dairy cows were used in this study, consisting of 20 in rearing sites with THI 66-70 (Pangalengan) and 78-82 (Sumedang), at 950 and 550 m above sea level, respectively. Basal rations were given every morning and evening, consisting of forage and concentrate. Temperature and humidity were recorded daily to determine the average daily THI. Blood samples in both groups of experimental animals were collected according to standard procedures every month during the 4 months of the experiment. Blood analysis followed procedures based on protocols from KIT Randox (UK), using a spectrophotometer.

Results: Lipid activity and regulation appeared higher (p < 0.05) in the group of lactating dairy cows kept at THI comfort zone 66-70 than at THI slight stress zone (78-82). Similarly, blood lipid levels were better (p < 0.05) in the cows in the comfort zone (66-70).

Conclusion: The study's results on the impact of the rearing zone of lactating local dairy cows appeared to affect the modulation of lipids in the body. Lipogenesis regulation and metabolism showed higher activity in the group of dairy cows reared in the comfort zone (THI = 66-70) compared to the group of dairy cows reared in the discomfort zone.

不同温湿指数区本地奶牛脂质调节的响应

目的：研究不同温湿指数（THI）的饲养场地区对当地泌乳奶牛代谢调节的影响。材料与方法：选取40头当地奶牛，其中20头产自海拔950和550 m、THI值为66-70 （Pangalengan）和78-82 （Sumedang）的养殖场。每天早晚饲喂饲粮，分别为草料和精料。每天记录温度和湿度，以确定平均每日THI。实验4个月期间，按标准程序每月采集两组实验动物的血液样本。血液分析遵循KIT Randox （UK）协议，使用分光光度计。结果：在THI舒适区（66 ~ 70）与轻度应激区（78 ~ 82）相比，在THI舒适区（66 ~ 70）饲养的泌乳奶牛脂质活性和调节水平显著提高（p < 0.05）。同样，舒适区（66 ~ 70）奶牛血脂水平也较好（p < 0.05）。结论：研究结果表明，饲养区对泌乳奶牛体内脂质调节有影响。舒适区（THI = 66 ~ 70）奶牛的脂肪生成调节和代谢活性高于不适区。
