Additive and non-additive genetic effects in Friesian, Jersey and Sahiwal crosses in Pakistan



Additive and non-additive genetic effects in Friesian, Jersey and Sahiwal crosses in Pakistan



Rising to the challenge breeding for the 21st Century customer Proceedings of the Thirteenth Conference Association for the Advancement of Animal Breeding and Genetics, Mandurah, Western Australia, 4th-7th July 1999: 243-246



Data on 4023 lactation records of Sahiwal cows and 2391 lactation records of Holstein x Sahiwal (HS) and Jersey x Sahiwal (JS) cattle (parity 1-5) in Punjab, Pakistan, were analysed to study breed effects for lactation milk yield (LMY), calving interval (CI), milk yield per day of calving interval (MCI), days open and days dry. Heterosis effects were significant and favourable for all production and fertility traits.
