The polymorphism in MUC1 gene in Nelore cattle

Journal of Animal Breeding and Genetics, 2007
SummaryMUC1 is a transmembrane glycoprotein expressed on the apical surfaces of the uterine epithelial tissue with predicted functions in protection and cell–cell adhesion. These properties are closely related with the repetitive region [variable number of tandem repeats (VNTR)] of the extracellullar domain and with the O‐glycosylation in their serine ...

Heritability estimate for stayability in nelore cows

Livestock Production Science, 2003
Abstract The objective of the present study was to determine the possibility of using stayability (STAY) of dams as a selection criterion for fertility in the Nelore breed. STAY was defined as whether or not a cow calved in a herd at a specific age or after this age given that she had calved at an earlier age. The specific ages studied were 5 (STAY5),

Genetic analysis on growth and carcass traits in Nelore cattle

Meat Science, 2012
In this study, the objective was to estimate genetic parameters of body weight at 210 (BW210) and 365 (BW365) days of age in relation to rib eye area (REA), subcutaneous back fat thickness (BF) and rump fat (RF), and their respective genetic trends, in Nelore beef cattle.

Fertility-associated proteins in Nelore bull sperm membranes

Animal Reproduction Science, 2006
The present study was undertaken to evaluate the protein composition of the sperm membranes (SM) of Nelore bulls, assessing protein markers associated with bull fertility, and whether these markers can be used for predicting bull fertility. Samples were obtained of 20 Nelore bulls, with fertility ranked and divided into three groups (greater, normal ...

VIABLE OOCYTE PRODUCTION RATE, EMBRYO TURNAROUND AND PREGNANCY RATE, IN NELORE P.O AND NELORE CEIP

Brazilian livestock has established itself as a global reference, driven by advancements in reproductive biotechnologies and the genetic improvement of the cattle herd. The use of techniques such as fixed-time artificial insemination (TAI), fixed-time embryo transfer (TETF), and in vitro embryo production (IVEP) has significantly accelerated genetic ...
