ESTIMATION OF GENETIC PARAMETERS OF SOME PRODUCTIVE AND REPRODUCTIVE PERFORMANCE ASPECTS IN FRIESIAN CATTLE

ESTIMATION OF GENETIC PARAMETERS OF SOME PRODUCTIVE AND REPRODUCTIVE PERFORMANCE ASPECTS IN FRIESIAN CATTLE

34 Friesian cows records were analyzed reared at AL-Iśhagi dairy cattle station (50 km north of Baghdad) during the period 1996-2005. Heritability estimates for milk yield 305 day (MY305d), the period between calving and first estrous, services per conceptions, day open, lactation period , dry peri...
