Impact of Model Parameterisation and Variance Component Estimates on Genomic Predictions of Carcass Traits in Montana Composite Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 431-442, May 2026.
ABSTRACT This study evaluated the influence of variance component (VC) estimates, obtained from different models and two relationship matrices, pedigree‐based (BLUP) and genomic information‐based (ssGBLUP), on genomic predictions of carcass traits in Montana composite cattle.

Mitochondrial control region genetic diversity and maternal ancestry of a Brangus-Ibage cattle populations

Genetics and Molecular Biology, 2005
The genetic diversity of 277 nucleotides in the mitochondrial DNA control region (nt 15,964 to 16,240 in reference sequence) was analyzed in crossbreed beef cattle (Brangus-Ibage, 5/8 Bos primigenius taurus x 3/8 Bos primigenius indicus) as well as in ...

Expressão de genes ligados à maciez da carne em bovinos da raça Nelore. [PDF]

, 2015
Dentre as características da carne, a maciez é a mais desejada pelo consumidor. Bovinos de origem Bos taurus indicus são conhecidos por produzirem carne de menor maciez quando comparado às raças de origem taurina.

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

Forage Species and Nutrition Among Reintroduced Banteng (Bos javanicus d'Alton, 1823) in Salakphra Wildlife Sanctuary and Khao Kiew–Khao Chompoo Wildlife Sanctuary, Thailand

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Dietary management is an important factor affecting the health and survival of critically endangered wildlife. The natural habitat showed a significant seasonal difference which was also higher than in introduced habitat. Reintroduced banteng exhibit dietary flexibility and adaptability to different natural habitats.

Risk factors related to resistance to Rhipicephalus (Boophilus) microplus and weight gain of heifers

Semina: Ciências Agrárias, 2015
The aim of the present study was to evaluate the influence of age and genetics in dairy heifers on resistance to the cattle tick Rhipicephalus (Boophilus) microplus and correlate these parameters with weight gain.

Wolf Presence Disrupts Seasonal Variation in Hair Cortisol Among Free‐Ranging Beef Cattle

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Predators exert indirect effects on prey populations beyond direct predation, but how predator reintroduction restructures prey physiology remains poorly understood. Using hair cortisol analysis in cattle exposed versus unexposed to wolves, we found that wolf presence disrupted normal seasonal cortisol regulation patterns.

The consequences of nuclear transfer for mammalian foetal development and offspring survival : a mitochondrial DNA perspective [PDF]

, 2004
Review of the articleThe introduction of nuclear transfer (NT) and other technologies that involve embryo reconstruction require us to reinvestigate patterns of mitochondrial DNA (mtDNA) transmission, transcription and replication.

Performance of Beef Cattle Under Grazing as Affected by Urochloa decumbens Cultivars

Grass and Forage Science, Volume 81, Issue 2, April-June 2026.
ABSTRACT Testing animal performance under grazing is fundamental to determine the potential of recently released, high‐yielding Urochloa decumbens hybrids. The objective was to evaluate the weight gain of young bulls grazing on pastures of U. decumbens cultivars Basilisk, BRS Carinás, and BRS Poraitê, as well as to assess the nutritive value and plant ...
