Effect of somatotropin on milk production of cross-bred dairy cows in the tropics



Effect of somatotropin on milk production of cross-bred dairy cows in the tropics



Veterinaria Mexico 26(2): 137-139



20 F1 Sahiwal-Holstein cows were selected according to body condition, health status and milk yield. Animals were divided into 2 groups of 10 cows each. Group 1 was injected s.c. with 250 mg of somatotropin (GH) every 14 days, and Group 2 did not receive any treatment. All cows grazed and were milked once a day with calf at foot. Milk yield in group 1 increased by 18% compared with group 2.
