Physiological Responses of Crossbred Saanen Goats to The Temperature Humidity Index (THI) at The Center for Livestock Training (BBPP) In Batu City

Abstrak

This study aimed to evaluate the physiological responses of Crossbred Saanen goats to the Temperature Humidity Index (THI) as an indicator of thermal comfort in a tropical environment. The research was conducted at the Center for Livestock Training (BBPP) Batu City in December 2024 - January 2025  using a case study method with direct observation. A total of nine lactating female Crossbred Saanen goats were observed, with measurements taken four times daily (morning, noon, afternoon, and night) over the course of one month. Parameters observed included environmental temperature and humidity for THI calculation, as well as heart rate, respiratory rate, rectal temperature, skin temperature, and lying frequency and duration as indicators of physiological and behavioral responses. The results showed that THI values ranged from 64.31 to 66.59, which are considered within the thermal comfort zone. However, both respiratory rate and skin temperature increased, particularly during midday, indicating a mild heat stress response. Rectal temperature and heart rate remained within normal physiological ranges. Lying activity increased during midday and early morning, reflecting behavioral adaptation to environmental conditions. It is concluded that Crossbred Saanen goats exhibit the ability to adapt to fluctuating tropical climates, but optimal environmental management is still required to maintain animal welfare and productivity.
