Genomic Prediction Ability Using Linear and Threshold Approaches for Different Stayability Definitions in Nellore Females

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Enhancing female longevity through regular calvings improves herd replacement rates and reduces the costs associated with replacing low reproductive efficiency animals. Stayability (STAY), defined as a cow's ability to remain productive in the herd, is a categorical trait that challenges traditional genetic evaluation due to its non‐normal ...

Development of equations to predict carcass weight, empty body gain, and retained energy of Zebu beef cattle

Animal, 2021
The accurate supply of energy is essential to optimize livestock productivity and profitability. Furthermore, replacing empty BW gain (EBG) with carcass gain (CG) might be a suitable alternative to estimate the retained energy (RE) of beef cattle.

Genetic Parameters of Methane Emission, Feed Efficiency, Feeding Behaviour, and Growth Traits in Beef Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Climate change has intensified the need to reduce greenhouse gas emissions, particularly methane (CH4) from enteric fermentation. Genetic selection has emerged as a promising mitigation strategy; however, studies on Bos taurus indicus , especially Nellore cattle, remain limited.

Quality of Forage Cactus Silage with the Addition of Hay from Forages Adapted to the Semiarid Region

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
This study investigated the effects of including hays from different forages adapted to the semiarid region on the forage cactus (Opuntia fícus‐indica (L.) Mill) silage quality. A completely randomized design, with five treatments was used: pure forage cactus and forage cactus associated with 30% hay from gliricidia (Gliricidia sepium), pornunça ...

No evidence for a recent genetic bottleneck in the endangered Sheko cattle breed (African Bos taurus) revealed by microsatellite analysis [PDF]

, 2009
Sheko is African taurine cattle, valued for its milk yield, adaptation to humid tsetse infested environment and trypanotolerance. We used 30 microsatellite markers in analyzing 30 DNA samples. We found high genetic diversity and no genetic bottlenecks in

In silico genomic and proteomic analyses of three heat shock proteins (HSP70, HSP90-α, and HSP90-β) in even-toed ungulates

Electronic Journal of Biotechnology, 2021
Background: Heat shock proteins (HSPs) play important roles in the responses to different environmental stresses. In this study, the genomic and proteomic characteristics of three HSPs (HSP70, HSP90-α and HSP90-β) in five even-toed ungulates (sheep ...

Livestock grazing boosts plant diversity in the Greater Serengeti–Mara Ecosystem

Ecological Applications, Volume 36, Issue 2, March 2026.
Abstract Intensifying land use is a global threat to biodiversity, and livestock grazing—occupying 26% of terrestrial land—is one of such threats. Designated protected areas are one of the key conservation strategies to halt biodiversity loss, but their effectiveness is debated, in part because of data shortage at relevant spatial scales (>1 ha).

Economic Impact and Disease Insights: Understanding Organ Condemnation in Cattle Slaughtered at Bahir Dar Abattoir

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
From 334 cattle slaughtered in the Bahir Dar municipal abattoir, different lesions resulting in total or partial organ condemnation were found in organs of 12 (3.6%) cattle. Organs affected by different lesions or disease were liver 14.6% (49/334), lung 9.9% (33/334), heart 2.40% (8/334), kidney 3.6% (12/334) and tongue 0.9% (3/334).

Reactivity of Nellore steers in two feedlot housing systems and its relationship with plasmatic cortisol [PDF]

, 2010
To evaluate reactivity to assess the temperament of Nellore steers in two feedlot housing systems (group pen or individual pen) and its relationship with plasmatic cortisol, 36 experimental units were observed five times at 28-day intervals of weight ...
