Body Weight Estimation in Holstein × Zebu Crossbred Heifers: Comparative Analysis of XGBoost and LightGBM Algorithms

open access: yesVeterinary Medicine and Science, Volume 11, Issue 4, July 2025.
This study evaluated the effectiveness of XGBoost and LightGBM algorithms for the purpose of live weight estimation in Holstein × Zebu crossbred heifers. In the analysis performed with a large biometric dataset, both models provided high accuracy, with the XGBoost algorithm standing out with R2 = 0.999 in the training set and R2 = 0.986 in the test set.

Assessment of runs of homozygosity islands and estimates of genomic inbreeding in Gyr (Bos indicus) dairy cattle

open access: yesBMC Genomics, 2018
Runs of homozygosity (ROH) are continuous homozygous segments of the DNA sequence. They have been applied to quantify individual autozygosity and used as a potential inbreeding measure in livestock species.

Experimental Determination of Labidus coecus Army Ant Diet: Novel Evidence for a Feeding Strategy

open access: yesBiotropica, Volume 57, Issue 4, July 2025.
Labidus coecus coffee shop experiment – faced with three choices—beef, fish, and apple with honey—the ants mainly chose beef. ABSTRACT Army ants prey mainly on invertebrates, occasionally attacking vertebrates. However, it remains unclear whether these attacks are defensive or for consumption.

Implementing Bos Indicus-Influenced Cattle in Utah for Hybrid Vigor [PDF]

open access: yes, 2023
Crossbreeding is a tool that cattle producers have used for decades. Hybrid vigor is one of the products of crossing breeding. One way to maximize hybrid vigor is by introducing Bos indicus genetics in a herd.

The Vertebrate Breed Ontology: Toward Effective Breed Data Standardization

open access: yesJournal of Veterinary Internal Medicine, Volume 39, Issue 4, July/August 2025.
ABSTRACT Background Limited universally‐adopted data standards in veterinary medicine hinder data interoperability and therefore integration and comparison; this ultimately impedes the application of existing information‐based tools to support advancement in diagnostics, treatments, and precision medicine.

Studies on restricted suckling in dual purpose and dairy breed cattle in Mexico [PDF]

open access: yes, 2005
The aim of this thesis was to investigate the effects of rearing calves by restricted suckling (RS) compared to artificial rearing (AR) in dual purpose and dairy breed cattle in Mexico, milked once or three times a day, respectively.

Impact of fetal vs. maternal contributions of Bos indicus and Bos taurus genetics on embryonic and fetal development1.

open access: yesJournal of Animal Science, 2019
To evaluate how the inclusion of Bos indicus genotype influences early fetal development in cattle, a reciprocal embryo transfer approach was used in a completely randomized design with a 2 × 2 × 2 factorial arrangement of treatments to generate 55 ...

Welfare of beef cattle

open access: yesEFSA Journal, Volume 23, Issue 7, July 2025.
Abstract This Scientific Opinion provides an assessment of beef cattle welfare focusing on risks related to flooring, water access, nutrition and feeding, high environmental temperatures, lack of environmental enrichment, lack of outdoor access, minimum space allowance and mixing practices. In addition, risks related to pasture and feedlots, weaning of
