COMPARE THE NUTRITIONAL CONTENT OF FAT OF ROW COW MILK FROM DIFFERENT REASON OF SIKAR DISTRICT

Abstract The nutritional composition of raw cow milk, particularly its fat content, is influenced by multiple factors such as breed, diet, environmental conditions, and management practices. This study aimed to investigate and compare the seasonal and regional variations in the fat content of raw cow milk collected from different private dairies across the Sikar district of Rajasthan. Milk samples were collected during the summer, rainy, and winter seasons and analyzed within 24 hours of collection using milk analyzer machines. All samples were stored at 4°C prior to analysis to preserve their quality.
The findings revealed significant (p ≤ 0.05) seasonal variation in milk fat content, while regional differences were non-significant (p > 0.05). The mean fat content was highest during the winter season (4.65 ± 0.0031 g/100g), followed by the rainy season (4.55 ± 0.0019 g/100g), and lowest during the summer season (3.91 ± 0.0019 g/100g). These results are consistent with previous studies reporting reduced milk fat in summer due to higher ambient temperatures and dietary changes that influence rumen acetate production. The observed seasonal differences may also be attributed to environmental temperature, feeding patterns, and physiological responses of cows to climatic stress.
Overall, the study concludes that seasonal variation significantly affects the fat content of cow milk, while geographical differences within the Sikar district do not. Understanding these patterns is crucial for dairy producers to optimize management practices, maintain milk quality, and ensure profitability.
Keywords Cow milk, fat content, seasonal variation, Sikar district, Rajasthan, milk nutrition, environmental influence.
