Calf mortality in crossbred dairy cattle
Tropical Animal Health and Production, 1980Information is given on crossbred calves between birth and 6 months of age belonging to 6 genetic groups--3 with 50% inheritance from Holstein, Jersey and Brown Swiss and the other 3 with 75% inheritance from 1 or 2 temperature dairy breeds. The mortality rate in 1,059 calves born was 3.87, 2.84 and 1.22% respectively under 1 month, from 1 to 3 and ...

Treatment of theileriosis in crossbred cattle in the Punjab
Tropical Animal Health and Production, 1993One hundred and nine cases of bovine tropical theileriosis (Theileria annulata infection) in Punjab State, India, were treated with oxytetracycline (23 cases) or buparvaquone (86 cases). Ages of affected cattle ranged from 6 days to 3 years. Oxytetracycline cured only 7 animals (30.4%), all of them calves below 15 days old, while buparvaquone cured all
