Abstract:
The present study was conducted on 123 lactating Deoni cows in 13 villages of Bidar district. A baseline survey was carried out to identify Deoni animals being reared by farmers in the breeding tract of Deoni cattle in the state of Karnataka under the project "Field Performance Recording of Deoni cattle in Bidar District a part of Rashtriya Gokul Mission sponsored by Karnataka Livestock Development Agency. The performance records from August 2017 to October 2018 were compiled and analysed using least squares analysis. Season of calving was recorded as summer (March to June), rainy (July to October) and winter (November to February) based on agro-climatic conditions of the region. Cows were divided based on age group, parity and season of calving to study the effect of each on lactation performance. The overall mean for milk fat, SNF protein, lactose and salt in Deoni cattle were observed to be 4.492 ± 0.0233, 8.181 ± 0.0117, 3.156 ± 0.0073, 4.410 ± 0.0112 and 0.6374 ± 0.00176 %, respectively. The non-significant differences in milk composition, in general, indicate that milk production function was not affected by season of calving or parity.
