Contribution of Fat Adjustment to Residual Feed Intake Estimation in Beef Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Including fat thickness as a covariate in the regression model used to calculate residual feed intake (RFI) could help preserve carcass quality traits, such as marbling, flavour and juiciness, by accounting for variation in fat deposition.

When Calves Get Vulnerable, Ocelots (Leopardus pardalis) Get Bold: A Camera Trap Record of Opportunistic Foraging in a Fragmented Landscape

Biotropica, Volume 58, Issue 2, March 2026.
We report the first confirmed record of an ocelot (Leopardus pardalis) dragging a newborn calf in a degraded forest fragment of southeastern Brazil. Using camera trap records, we reveal an opportunistic foraging event involving a vulnerable domestic prey within a highly fragmented landscape.

Is the American Zebu really Bos indicus?

Genetics and Molecular Biology, 1999
The American continent was colonized in the 16th century by Europeans who first introduced cattle of Bos taurus origin. Accounts register introduction of Bos indicus cattle into South America in the 19th and continuing through the 20th century, and most ...

Genomic Analysis of Taurine and Indicine Ancestry in the Montana Tropical Composite Population

Journal of Animal Breeding and Genetics, Volume 143, Issue 2, Page 273-282, March 2026.
ABSTRACT The Montana Tropical cattle, a Taurine and Indicine composite, were developed in Brazil since 1994 and were based on crossing four biological types of cattle: zebu (mainly Nelore), tropical adapted taurine (mainly Senepol and Romosinuano), British taurine (mainly Angus) and continental taurine (as Charolais, Simental and Limousin).

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 ...

Climate factors drive the local adaptation of Old World cattle

iMeta, Volume 5, Issue 1, February 2026.
Climate adaptation genomics of cattle. We comparatively analyzed genomic data from 85 Old World cattle breeds/populations of Eurasia and Africa to identify genetic factors associated with climate factors. Environmental genome‐wide association studies revealed 3165 single‐nucleotide polymorphisms (SNPs) with strong correlations between climate factors ...

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

Effects of Liposome‐Encapsulated α‐Pinene on In Vitro Oocyte Maturation and Embryo Development in Bovine Species

Molecular Reproduction and Development, Volume 93, Issue 2, February 2026.
ABSTRACT Oocyte in vitro maturation (IVM) represents a crucial phase in embryo production, often compromised by reactive oxygen species (ROS). Strategies to mitigate ROS are essential to improve oocyte quality. This study investigated the effects of liposome‐encapsulated α‐pinene (Lip‐α‐pinene) on bovine oocyte IVM and embryonic development following ...
