Components of (co)variance and genetic parameters were estimated for adjusted weights at ages 120 (W120), 240 (W240), 365 (W365) and 450 (W450) days of Polled Nellore cattle raised on pasture and born between 1987 and 2010. Analyses were performed using an animal model, considering fixed effects: herd-year-season of birth and calf sex as contemporary groups and the age of cow as a covariate. Gi...

Abstract Community-based sheep breeding programs (CBBPs) have been adopted strategically to improve Bonga sheep, the most popular breed in Ethiopia. The present study was undertaken estimate genetic parameters and trends for growth traits inbreeding levels each CBBP. Data pertaining traits, spanning a period of seven years (2012–2017), were collected from 14 CBBPs. analyzed using General Linear...
The weight records from Simmental beef cattle were used in a genetic evaluation of growth with or without the inclusion of animals obtained by embryo transfer. A multi-trait model in which embryo transfer individuals were excluded (MTM1) contained 29,510 records from 10,659 animals, while another model without exclusion of these animals (MTM2) contained 62,895 weight records from 23,160 animals...
