AbstractFull Text

Generic equations were derived using probability and transition matrices to track the flow of genes originating from a purebred or crossbred mating. Cumulative discounted expressions (CDE) were calculated for annual, replacement heifer, cull cow, birth, yearling, and slaughter traits using input...

Abstract

Inbreeding coefficients and effective number of founders, ancestors, and remaining genomes were computed for the animals registered from 1994-1998, based on pedigrees tracing back to breed origin. The Pedig package, gently provided by Dr. Didier Boichard, was used. The numbers of annually...

Abstract

A MOET selection nucleus linked to a progeny testing scheme was implemented in 1994 for the improvement of the Guzerá, a dual purpose breed, in Brazil. In the first 47 attempts to produce full-sib families, 13 already completed one lactation, 5 donors failed to respond to the multi-ovulation...

Abstract

A 28-month experiment was conducted at Valença, Rio de Janeiro, Brazil, to assess the effect of B. microplus infestations on the milk yield of 117 cows of 3 Holstein-Friesian (HF) × Guzera crossbred groups (F1, 5/8 HF and ≥15/16 HF). Cows were randomly allocated to 2 treatments during their whole...
