Ingestive behavior of Nellore cows and their straightbred or crossbred calves Comportamento em pastejo de vacas Nelores amamentando bezerros Nelores ou mestiços Simental × Nelore

open access: yesRevista Brasileira de Zootecnia, 2010
This trial aimed to investigate the influence of calf genetic group on the ingestive behavior of Nellore dams and their offspring on pasture. Twenty one primiparous and multiparous Nellore cows were assigned to the experiment; 13 cows nursed straightbred Nellore calves; and eight cows nursed halfbred Simmental × Nellore calves.

Diet‐Related Differences Predominate Over Breed‐Associated Differences in Hepatic Lipid Metabolism, Antioxidant Vitamins and Lipid Quality Indices Among Beef Cattle

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Understanding how nutritional management and genetic background influence hepatic metabolism is important for improving the nutritional quality of bovine products in tropical production systems. This study evaluated breed‐associated differences under a common dietary regimen and diet‐related differences within the Nelore breed with respect to ...

Impact of Reactive Temperament on Bull Fertility in Natural Service

open access: yesReproduction in Domestic Animals, Volume 61, Issue 11, November 2026.
ABSTRACT The study aimed to evaluate the influence of temperament on semen quality and fertility in Nelore bulls. Two groups were selected based on ethological analysis, consisting of animals with either calm temperament (CA, n = 8) or reactive temperament (RE, n = 8).

PSXIV-9 Effect of fiber level on the performance of Nelore and ½ Angus-Nelore cattle.

open access: yesJournal of Animal Science
Abstract Diets with high grain inclusion have become increasingly common in Brazilian feedlots. Data from our laboratory (Caetano et al., 2015) demonstrated that the feed intake of purebred Nelore cattle was maximized only at fiber levels above 11% neutral detergent fiber from forage (fNDF).

Implementation of Metafounders in the Genomic Prediction for the Polled Trait in Brahman Cattle Using a Multi‐Breed Population

open access: yesAnimal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT The absence of horns (polled trait) in cattle is associated with better animal welfare by reducing the need for dehorning. In Brahman cattle, population size and the scarcity of phenotypic records challenge the accuracy of genomic predictions for this trait.

A Nelore Cattle Structural Variant Catalog

open access: yesAnimal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT Structural variants (SVs) contribute more nucleotide divergence between mammalian genomes than single nucleotide polymorphisms, yet no population‐scale, long‐read‐validated SV catalog has been available for Bos indicus cattle. Nelore, the most numerically important indicine breed worldwide, diverges substantially from the taurine‐derived ...
