Environmental variation effects fertility in tropical beef cattle. [PDF]

Transl Anim Sci, 2022
Abstract The northern Australia beef cattle industry operates in harsh environmental conditions which consistently suppress female fertility. To better understand the environmental effect on cattle raised extensively in northern Australia, new environmental descriptors were defined for 54 commercial herds located across the region. Three

Unraveling genetic sensitivity of beef cattle to environmental variation under tropical conditions [PDF]

Genetics Selection Evolution, 2019
Background Selection of cattle that are less sensitive to environmental variation in unfavorable environments and more adapted to harsh conditions is of primary importance for tropical beef cattle production systems.

β-glucanase and xylanase for beef cattle on tropical pasture

Semina: Ciências Agrárias
The aim of this study was to assess the impact of administering an energy-protein supplement with fibrolytic enzymes, either singly or in a blend, on the intake, digestibility, ruminal, and metabolic parameters in grazing beef cattle.

Evaluation of a Model (RUMINANT) for Prediction of DMI and CH₄ from Tropical Beef Cattle. [PDF]

Animals (Basel), 2023
Simulation models represent a low-cost approach to evaluating agricultural systems. In the current study, the precision and accuracy of the RUMINANT model to predict dry matter intake (DMI) and methane emissions from beef cattle fed tropical diets (characteristic of Colombia) was assessed.

Prediction of Pasture Intake by Beef Cattle in Tropical Conditions [PDF]

Tropical Animal Health and Production, 2021
Abstract A meta-analytic study was conducted to develop and evaluate models for the prediction of pasture dry matter intake (DMIpasture) by beef cattle in tropical conditions. 804 individual observations of DMIpasture were used, taken from 23 studies through analysis of mixed models, including the study as a random effect.

Evaluation of nonadditive effects in yearling weight of tropical beef cattle. [PDF]

J Anim Sci, 2018
Nonadditive effects may contribute to genetic variation of complex traits. Their inclusion in genetic evaluation models may therefore improve breeding value estimates and lead to more accurate selection decisions. In this study, we evaluated a systematic series of models accounting for additive, dominance and first-order epistatic interaction (additive

The association between natural drinking water sources and the emergence of zoonotic leptospirosis among grazing beef cattle herds during a human outbreak

One Health, 2022
Leptospirosis is a zoonotic bacterial disease associated with water abundance in tropical and temperate climate zones. Bacterial spread may also occur in dry and warm weather conditions when humans and animals are forced to share depleted water sources ...

Production potential of beef cattle in tropical pastures: a review [PDF]

Ciência Animal Brasileira, 2021
Abstract The expression production potential represents the maximum amount of products that can be obtained per unit area. However, what is the maximum amount of product that can be obtained in a pasture area? To answer this question, it is necessary to understand the factors related to forage accumulation, grazing efficiency, chemical composition of ...

Genome-wide association study for carcass weight in pasture-finished beef cattle in Hawai’i

Frontiers in Genetics, 2023
Introduction: Genome-wide association studies (GWAS) have identified genetic markers for cattle production and reproduction traits. Several publications have reported Single Nucleotide Polymorphisms (SNPs) for carcass-related traits in cattle, but these ...
