Aromatase gene and its effects on growth, reproductive and maternal ability traits in a multibreed sheep population from Brazil
Provedor de dados: Genetics and Molecular Biology
Autores: Lôbo,Ana Maria Bezerra Oliveira; Lôbo,Raimundo Nonato Braga; Paiva,Samuel Rezende.
We determined the polymorphism C242T of the aromatase gene (Cyp19) and its allelic frequency, as well as the effect of the variants on productive and reproductive traits in 71 purebred Santa Inês sheep, 13 purebred Brazilian Somali sheep, nine purebred Poll Dorset sheep, and 18 crossbred 1/2 Dorper sheep. The animals were genotyped using the PCR-RFLP technique. The influence of the animal's genotype on its performance or on the performance of its lambs was analyzed by the least square method. Another factor assessed was the importance of the animal's genotype in analysis models for quantitative breeding value estimates, and whether there were differences among the averages of breeding values of animals with different genotypes for this gene. In the sample...

Genetic parameters for growth, reproductive and maternal traits in a multibreed meat sheep population
Provedor de dados: Genetics and Molecular Biology
Autores: Lôbo,Ana Maria Bezerra Oliveira; Lôbo,Raimundo Nonato Braga; Paiva,Samuel Rezende; Oliveira,Sônia Maria Pinheiro de; Facó,Olivardo.
The genetic parameters for growth, reproductive and maternal traits in a multibreed meat sheep population were estimated by applying the Average Information Restricted Maximum Likelihood method to an animal model. Data from a flock supported by the Programa de Melhoramento Genético de Caprinos e Ovinos de Corte (GENECOC) were used. The traits studied included birth weight (BW), weaning weight (WW), slaughter weight (SW), yearling weight (YW), weight gain from birth to weaning (GBW), weight gain from weaning to slaughter (GWS), weight gain from weaning to yearling (GWY), age at first lambing (AFL), lambing interval (LI), gestation length (GL), lambing date (LD - number of days between the start of breeding season and lambing), litter weight at birth (LWB)...
