Four healthy lactating cows from each breed were selected from a herd of Livestock Research Center, NDRI, Karnal. All animals were fed as per the ICAR (2013) feeding standard. Physiological parameters like respiration rate, pulse rate, blood pressure, rectal temperature, skin surface temperature (...
For none of the analysed characteristics a significant breed 脳 treatment interaction was detected. The 640-mg dosage gave optimum results: in the treatment period the calculated milk energy output increased on an average 19% in Dutch Red and White, Jersey and Friesian cows by an increase in ...
The paper considers the impact of the growth intensity of black-and-white cows on subsequent dairy productivity. The main growth indicators of cows of different productivity levels are calculated on the basis of breeding and accounting documents from the
