ABSTRACT

Indonesia is a country which has high level of temperature and humidity. The higher level of temperature
and humidity happens due to tropical zone. Then, these conditions may causes the rise of the THI which leads to
heat stress. Furthermore, heat stress is the inability situation to release body heat, resulting a lot of physiological
changes. The changes that may affect the level of milk protein and fat contents. Therefore, this research aimed to
determine the effect of different tropical climate zone in Indonesia on milk protein and fat in dairy cows. Twelve
Friesien Holstein cows were used in this research. Those cows were in multiparous milk lactation period. Milk and
physiological parameter in dry and wet season was observed in this research. Then, the data was analyzed using
Statistical Analysis Software (SAS) version 9.3 for windows. Milk protein and fat levels were compared based on the
dry and wet season. Based on the research, it was found that wet season caused a decrease in protein which was
indicated by the numerical changes on group category.
