Genomic selection in multi-breed dairy cattle populations. Author(s): SILVA, M. V. G. B. Abstract Genomic selection has been a valuable tool for increasing the rate of genetic improvement in purebred dairy cattle populations. However, there also are many large populations of crossbred dai... ... Repository: BDPA Publication year: 2016
Profile of cattle breed sensitivity to the tick Rhipicephalus microplus. Author(s): ANDREOTTI, R. ABSTRACT - Among cattle, Bos taurus breeds and their crosses are more sensitive to tick infestations than Bos indicus breeds that are more resistant to infestation and more adaptable to tropical clima... ...

Genetic analysis of productive and reproductive traits in multiple-breed dairy cattle populations. Author(s): SILVA, M. V. G. B.; PANETTO, J. C. do C. The objective of this work was to determine whether the random regression model using linear splines (RRMLS) is suitable to estimate the genetic parameters for productive and reproductive traits of a... ...

Pedigree analyses in the breeding program for nellore cattle. Author(s): MARCONDES, C. R. Parameters based on the probability of gene origin were used to describe genetic variability in three reproductive groups from the Breeding Program for Nellore Cattle (PMGRN). The three reproductive p... ... Repository: BDPA Publication year: 2007
Effect of sire breed on carcass and beef quality of crossbred cattle. Author(s): FEIJO, G. L. D.; MENEZES, G. R. de O.; GOMES, R. da C.; TORRES JUNIOR, R. A. de A. The aim of this study was to evaluate the effect of sire breed on beef quality of crossbred cattle. Steers (n=74) and heifers (n=71) produced along two years from mating Nellore, ½ Nellore x ½ Angus a... ... Repository: BDPA Publication year: 2016
An insight into the linkage disequilibrium map of the Canchim beef cattle breed. The development of linkage disequilibrium (LD) maps is very important for understanding the nature of non-linear association between phenotypes and genes, as LD can be defined as the non-random segreg... ...

Effect of sire breed on performance and feed efficiency in feedlot of crossbred cattle. Author(s): MENEZES, G. R. de O.; GOMES, R. da C.; TORRES JUNIOR, R. A. de A. The aim of this study was to evaluate the effect of sire breed on performance and feed efficiency in feedlot of crossbred cattle. Steers (n=74) and heifers (n=71) produced along two years by breeding... ... Repository: BDPA Publication year: 2016
Curraleiro Pé Duro cattle breed (Bos taurus) differ in phagocytic Neutrophil function related to crossbreed cattle (Bos taurus X Bos indicus). This work aimed to evaluate hematological parameters and phagocytic neutrophil functions of naturally selected Curraleiro Pé Duro cattle breed (Bos taurus) and crossbreed cattle (Bos taurus X Bos indi... ...

Performance, carcass, and meat traits of locally adapted Brazilian cattle breeds under feedlot conditions. Author(s): EGITO, A. A. do; JULIANO, R. S.; RAMOS, A. F.; FEIJO, G. L. D.; COSTA, M. F. O. e Abstract: Little is known about the performance, carcass, and meat traits of locally adapted cattle in Brazil. This study aimed to compare the growth, slaughter, and carcass traits as well as meat qua... ... Repository: BDPA Publication year: 2023
Single nucleotide variants and InDels identified from whole-genome re-sequencing of Guzerat, Gyr, Girolando and Holstein cattle breeds. Whole-genome re-sequencing, alignment and annotation analyses were undertaken for 12 sires representing four important cattle breeds in Brazil: Guzerat (multi-purpose), Gyr, Girolando and Holstein (da... ...
