Abstract: The study was undertaken to evaluate the effect of climatic parameters on milk quality of Deoni cattle. The duration of research work was 52 weeks on available Deoni cows at Cattle Cross Breeding Project, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. The readings of temperature and humidity in cattle shed will be recorded twice in a day by using wet and dry bulb thermometer and the data of temperature, humidity, evapotranspiration, sunshine hours, wind velocity of surrounding environment was taken from meteorological observatory at the university campus which is situated in the vicinity of this farm, to investigate the seasonal variations of milk from Deoni cows during summer, rainy and winter season. It was observed that average fat percentage (3.57 + 0.016) and SNF percentage (8.55 + 0.008). Climatic variables such as temperature and humidity related parameter found to have negative relationship with milk fat and SNF percentage where as sunshine hours was a positive relation. All the climatic factors considered in the study accounted for 58 per cent direct variation on fat percentage and 69 per cent direct variation on SNF percentage verified by value of coefficient of determination(R²). As Deoni cattle are originated in this region they did not suffer much for heat stress.
