Candidate SNP of CACNA2D1 Gene Associated with Clinical Mastitis and Production Traits in Sahiwal (Bos taurus indicus) and Karan Fries (Bos taurus taurus × Bos taurus indicus)

Animal Biotechnology, 2018
The present study was conducted to identify polymorphisms in CACNA2D1 gene and their association with clinical mastitis and production traits. Exon 18 and its flanking regions were screened for the presence of SNPs. Statistical analysis was performed to identify association of period of birth, breed, and genotype with mastitis incidence on randomly ...

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.

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).

Effect of Fsh β-Sub Unit and Fshr Genes Polymorphisms on Superovulatory Response Traits [PDF]

, 2014
Follicle stimulating hormone (FSH) is a pituitary expressed glycoprotein hormone that regulatesreproduction in mammals which composed of α and β-sub unit. The β-sub unit dictates its bindingspecificity with their receptor (FSHR).

Biometria testicular de touros Nelore (Bos taurus indicus) e touros cruzados Nelore-europeu (Bos taurus indicus x Bos taurus taurus) aos 20 e 24 meses de idade

Brazilian Journal of Veterinary Research and Animal Science, 2002
O objetivo deste trabalho foi estudar os efeitos da idade, do grupo genetico e da interacao entre idade e grupo genetico, sobre as biometrias testiculares (circunferencia escrotal e consistencia testicular) Foram avaliados, aos 20 e 24 meses de idade, 190 touros Nelore e 447 touros cruzados Nelore-europeu. Aos 24 meses os exames foram repetidos.

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 ...
