Productive performance, nutrient digestion and metabolism of Holstein (Bos taurus) and Nellore (Bos taurus indicus) cattle and Mediterranean Buffaloes (Bubalis bubalis) fed with corn-silage based diets
(ELSEVIER SCIENCE BV, 2011)
The objective of this study was to evaluate the productive performance, nutrients digestion and metabolism of three different genetic groups fed with the same diet based on corn silage. 30 heifers in growth were used of ...
Degradabilidade ruminal do amido de silagem de milho, farelo de soja e sorgo grão, em bovinos da raça Nelore
(1997-03-01)
Four Bos indicus (Nellore) ruminally-fistulated animals, averaging 36 months of age and 520 kg, were used in a randomized block design to study the ruminal degradability of starch in corn silage, soybean meal, and sorghum ...
Revealing misassembled segments in the bovine reference genome by high resolution linkage disequilibrium scan
(2016-09-05)
Background: Misassembly signatures, created by shuffling the order of sequences while assembling a genome, can be detected by the unexpected behavior of marker linkage disequilibrium (LD) decay. We developed a heuristic ...
Superovulation and embryo transfer in Bos indices cattle
(Elsevier B.V., 2006-01-07)
Compared to Bos taurus breeds, Bos indices breeds of cattle present several differences in reproductive physiology. Follicular diameter at deviation and at the time of ovulatory capability are smaller in B. indicus breeds. ...
Effects of dominant follicle aspiration and treatment with recombinant bovine somatotropin (BST) on ovarian follicular development in Nelore (Bos indicus) heifers
(Elsevier B.V., 2000-08-01)
Follicle ablation has been recognized as an efficient method of follicular wave synchronization. Treatment with recombinant bovine somatotropin (BST) has been shown to enhance follicular development in <(Bos taurus)under ...
Impacts of Reproductive Technologies on Beef Production in South America
(Springer, 2014-01-01)
The majority of beef cow herds in South America are constituted by Bos indicus females, which have particular reproductive features that contribute to reduced reproductive efficiency compared with that of B. taurus cohorts. ...
Genome wide scan for quantitative trait loci affecting tick resistance in cattle (Bos taurus x Bos indicus)
(BIOMED CENTRAL LTD, 2010)
Background : In tropical countries, losses caused by bovine tick Rhipicephalus (Boophilus) microplus infestation have a tremendous economic impact on cattle production systems. Genetic variation between Bos taurus and Bos ...
Genome wide scan for quantitative trait loci affecting tick resistance in cattle (Bos taurus × Bos indicus)
(2010-04)
Abstract
Background
In tropical countries, losses caused by bovine tick Rhipicephalus (Boophilus) microplus infestation have a tremendous economic impact on cattle production systems. Genetic variation ...
Influence of sire breed (Bos indicus versus Bos taurus) and interval from slaughter to oocyte aspiration on heat stress tolerance of in vitro-produced bovine embryos
(Elsevier B.V., 2011-10-01)
Based on in vitro experiments, Bos indicus embryos were more resistant to heat stress (HS) than Bos taurus embryos. To increase knowledge regarding differences between Bos indicus and Bos taurus in resistance to HS, the ...
Candidate SNPs for carcass and meat traits in Nelore animals and in their crosses with Bos taurus
(Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 2012-02-01)
O objetivo deste trabalho foi avaliar os efeitos de polimorfismo de nucleotídeo único (SNP) dos genes IGF1 (AF_017143.1:g.198C>T), MSTN (AF_320998.1:g.433C>A), MYOD1 (NC_007313:g.1274A>G) e MYF5 (NC_007303:g.1911A>G) nas ...
