Effect of Housing and Management on Microclimate of Shed and Milk Yield of Dairy Cattle in Coastal Climate of Goa

Ten farmers from each of the six talukas (Pernem, Bicholim, and Ponda talukas of North Goa district; Salcete, Canacona, and Sanguem talukas of South Goa district) were considered for this study based on cattle population with the goal of developing suitable housing systems to improve animal comfort and increase the productivity of the animals. Farmers were interviewed in order to get information on dairy cattle housing and production. Farmers were then divided into groups based on the sort of dairy home they owned. Aside from feeding and disease occurrence, data on the microenvironment of the cattle shed and daily milk yield of cows were recorded. According to the data, cow shed orientation had a significant (P 0.05) effect on average daily milk yield, average daily air temperature, and average daily relative humidity, but a highly significant (P 0.01) effect on average daily temperature humidity index. In cattle houses with an east-west orientation, there was less heat stress and increased milk output. Ventilation of the cattle shed had a highly significant (P 0.01) effect on the average daily milk yield, as well as a substantial (P 0.05) effect on the average daily air temperature, relative humidity, and temperature humidity index. In calf sheds with good ventilation, significantly better milk yield (9.896 0.090 kg), significantly lower air temperature (27.62 0.13°C), and significantly lower relative humidity (79.43 0.35 percent) were observed. The provision of floor space inside the cattle shed had a significantly significant (P 0.01) impact on the average daily milk output and all microenvironments. In cattle sheds where standard floor space of minimum 5 m2 per cattle was maintained, average daily milk yield (9.736 0.085 kg) was significantly greater, while average daily relative humidity (79.88 0.37 percent) was much lower. The effect of a cooling arrangement in the cattle house on the average daily milk yield and all micro environmental indicators was highly significant (P 0.01). It was hypothesised that, in addition to human and mechanical cooling, if a fake ceiling was installed within the cattle house, the cows would feel more at ease and produce more milk.
