Fertility in a herd of Holstein-Friesian and Brown Swiss cows in Venezuela


, : Fertility in a herd of Holstein-Friesian and Brown Swiss cows in Venezuela. Memoria, Asociacion Latinoamericana de Produccion Animal 11: 64

For 112 Holstein-Friesian (HF) and 43 Brown Swiss (BS) cows, calving interval averaged 495.8 days and the number of services required/conception 2.82. The BS cows had better fertility than HFs, and cows calving in the rainy season performed better than those calving in the dry season. Gestation length and calf birth weight averaged 282.2 days and 35.4 kg resp.
