Autor: Helton Mattana Saturnino, Maria de Fátima Ávila Pires, Ademir de Moraes Ferreira, R. L. Teodoro

Publikováno v: Arquivo Brasileiro de Medicina Veterinária e Zootecnia. 54:57-63

A taxa de gestação de vacas em lactação e de novilhas confinadas em free stall foi avaliada durante o inverno e o verão, nos anos de 1993, 1994 e 1995. A temperatura ambiente (TA) e a umidade relativa do ar (UR) foram acompanhadas diariamente, d

The value of F1 dairy Bos taurus-Bos indicus embryos for milk production in poor environments

Autor: Fernando Enrique Madalena, R. L. Teodoro, Ch. Smith

Publikováno v: Journal of Animal Breeding and Genetics. 113:471-482

Summary Literature summaries were used to estimate the economic value of F1 dairy crosses of Bos taurus and Bos indicus for milk production in unfavourable environments, in relation to five continuous breeding systems. The continuous systems included

Differential expression of genes in resistant versus susceptible Gyr x Holstein cattle challenged with the tick Rhipicephalus (Boophilus) microplus

The bovine tick Rhipicephalus (Boophilus) microplus causes major losses in cattle production systems in tropical regions. Bos indicus breeds are more resistant to ticks than B. taurus breeds. Resistance genes could be an alternative to control this p

Publikováno v: Developments in biologicals. 132

Genetic differences in susceptibility to ticks (Rhipicephalus (Boophilus) microplus) are considerable in bovines. Here, mapping, association and gene expression approaches were employed to further advance our understanding of the molecular basis of t

Publikováno v: Genetics and molecular research : GMR. 5(3)

Genetic trends for 305-day milk yield (P305) in Brazilian Guzerat herds under selection were compared. Data from 4898 lactations of 3179 purebred and crossbred cows from various regions of Brazil were used. Milk yield was adjusted for mature age and

Recent reports identified DGAT1 (EC 2.3.1.20) harboring a lysine to alanine substitution (K232A) as a candidate gene with a strong effect on milk production traits. Our objective was to estimate the frequency of the DGAT1 K232A polymorphism in the ma

Losses caused by bovine tick burdens in tropical countries have a tremendous economic impact on production systems. Besides reducing production, this parasite can cause death in the most susceptible animals. The use of commercial acaricides has been
