Abstract

A study was performed to investigate the impact of heat stress on milk composition and fatty acid profile in crossbred and Vechur cattle. The study was organized in two periods, period 1 with minimum Temperature Humidity Index (THI) (December 2022 to January 2023) and period 2 with maximum THI (March 2023 to April 2023). Six milk samples collected from lactating crossbred and Vechur cows were subjected to analysis. Milk composition analysis revealed no significant difference (p>0.05) between breeds and periods. The milk fatty acid analysis was accomplished using Gas chromatography-mass spectrometry (GC-MS). Six saturated, two monounsaturated and one polyunsaturated fatty acids were analysed. Among the analysed saturated fatty acids, the palmitic and caprylic acids showed a significant difference in milk samples of crossbred cattle with a surge in mean value during period 2 (p <0.05). However, in Vechur milk only stearic acid showed a significant difference with an increased mean in period 2. Monounsaturated fatty acids showed a significant difference in crossbred milk with an increased mean during period 2 (p <0.05). The only polyunsaturated fatty acid analysed in the work was linolenic acid. Compared to crossbred cattle, Vechur milk showed a decrease in the quantum of linolenic acid which is statistically significant (p <0.05) during period 2.
