This Research aimed to evaluate the metabolic status and behavior changes during the transition period in dairy goats from three breeds, under tropical conditions. Thirty multiparous female goats were kept in pens, distributed randomly by breeds. Infrared cameras were fitted in the pens to monitor the animals, and its activities were recorded. Goats displayed varied idle, standing, walking, and feeding behaviors at kidding day ( < 0.10) when compared with the days after and before. Agnostic interactions prevailed between 3.33 and 7.98% of the time on the day of kidding. There was a day effect for the exploratory activities ( < 0.10), where the most exploratory activities were observed on the day of kidding. The milk production and fat content differed according to breed and lactation week. Collective pens for lactating goats, kept in a tropical environment, do not compromise the social behavior and welfare.
本研究旨在评估热带条件下三个品种奶山羊过渡期的代谢状况和行为变化。30只经产母羊被饲养在围栏中，按品种随机分布。围栏内安装了红外摄像机以监测动物，并记录其活动。与产羔前后的日子相比，山羊在产羔日表现出不同的闲置、站立、行走和进食行为（<0.10）。产羔日有3.33%至7.98%的时间存在争斗互动。探索活动存在日效应（<0.10），产羔日观察到的探索活动最多。产奶量和脂肪含量因品种和泌乳周而异。饲养在热带环境中的泌乳山羊集体围栏不会损害其社会行为和福利。
