Genetic Parameters of Resilience Indicators Across Growth in Beef Heifers and Their Associations With Weight, Reproduction, Calf Performance and Pre‐Weaning Survival

Journal of Animal Breeding and Genetics, Volume 143, Issue 1, Page 79-91, January 2026.
ABSTRACT In tropical extensive beef cattle systems, heifers raised on pasture are exposed to various environmental challenges that affect their growth and reproductive performance during the first breeding. Resilience indicators derived from deviations in longitudinal traits can quantify the magnitude of these challenges and the ability of an animal to

Treatments to Optimize the Use of Artificial Insemination and Reproductive Efficiency in Beef Cattle under Tropical Environments

Veterinary Medicine International, 2011
Bos indicus cattle, the preferred genetic group in tropical climates, are characterized by having a lower reproductive efficiency than Bos taurus. The reasons for the poorer reproductive efficiency of the Bos indicus cows include longer lengths of ...

Indirect Genomic Predictions for Indicine Cattle Breeds With SNP Effects From a Multi‐Breed Genomic Evaluation

Journal of Animal Breeding and Genetics, Volume 143, Issue 1, Page 172-182, January 2026.
ABSTRACT Indirect predictions (IP) are used for young genotyped animals that lack phenotypes (of their own or from progeny) or are from commercial herds. The former can be left behind because they do not contribute to the official genomic evaluations.

Population Structure, and Selection Signatures Underlying High-Altitude Adaptation Inferred From Genome-Wide Copy Number Variations in Chinese Indigenous Cattle

Frontiers in Genetics, 2020
Copy number variations (CNVs) have been demonstrated as crucial substrates for evolution, adaptation and breed formation. Chinese indigenous cattle breeds exhibit a broad geographical distribution and diverse environmental adaptability. Here, we analyzed

Impact of FSH‐Induced Ovarian Stimulation on Oocyte Recovery and In Vitro Embryo Production in the Red Sindhi Cows

Reproduction in Domestic Animals, Volume 61, Issue 1, January 2026.
ABSTRACT Follicle‐stimulating hormone (FSH) plays an important role in regulating reproductive events, particularly follicular development and oocyte competence acquisition. Some studies using FSH protocols in zebu cattle were performed, but data regarding its application in the Red Sindhi breed are scarce and therefore warranted. In this context, this

Quantitative trait locus affecting birth weight on bovine chromosome 5 in a F2 Gyr x Holstein population

Genetics and Molecular Biology, 2005
Segregation between a genetic marker and a locus influencing a quantitative trait in a well delineated population is the basis for success in mapping quantitative trait loci (QTL). To detect bovine chromosome 5 (BTA5) birth weight QTL we genotyped 294 F2

Genomic insights into the population structure and genetic diversity of Ugandan indigenous cattle

Animal Genetics, Volume 56, Issue 6, December 2025.
Abstract Domestic cattle in Africa can be categorized as either taurine (Bos taurus) or indicine (Bos indicus) based on their domestication histories from the extinct aurochs (Bos primigenius). Close to 150 breeds of indigenous cattle are estimated to exist in Africa and have a complex mixture of B. taurus and B. indicus ancestries.
