Influence of MC1R Gene Variants on Coat Color of Indicine Cattle Breeds [PDF]

Animal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT Indicine cattle display a broad range of coat colors, representing a relevant and breed‐defining trait required for registration in breeder association. Among the genes involved in pigmentation, MC1R stands out for modulating the synthesis of melanin‐related proteins and remains poorly explored in indicine cattle breeds. Therefore, we aimed to

Genetic Parameters for Novel Feedlot Profitability‐Related Traits in Nelore Cattle [PDF]

Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 411-421, May 2026.
ABSTRACT This study aimed to estimate (co)variance components and genetic parameters for accumulated profitability (AFP) and profit per kilogram of liveweight gain (PFT), and their relationships with weight at 450 days of age (W450), scrotal circumference at 365 days of age (SC365), age at first calving (AFC), probability of precocious calving at 30 ...

Genomic Prediction Ability for Novel Profitability Traits Using Different Models in Nelore Cattle [PDF]

Journal of Animal Breeding and Genetics, Volume 143, Issue 2, Page 244-255, March 2026.
ABSTRACT The aim of this study was to assess the accuracy, bias and dispersion of genomic predictions for accumulated profitability (APF) and profit per kilogram of liveweight gain (PFT) in Nelore cattle using different prediction approaches. The dataset consisted of 3969 phenotypic records for each trait. The pedigree harboured information from 38,930

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

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).

Advances in the Use of Recombinant Gonadotropins for Reproductive Biotechnologies in Ruminants: A Review [PDF]

Reproduction in Domestic Animals, Volume 61, Issue 5, May 2026.
ABSTRACT Recombinant gonadotropins, particularly recombinant follicle‐stimulating hormone (rFSH) and recombinant equine chorionic gonadotropin (reCG), have emerged as viable alternatives to traditional animal‐derived hormones in reproductive biotechnologies. This review aims to provide an updated and comprehensive overview of recombinant gonadotropins,

Integrative Genomics Identifies Candidate Genes Underlying Trypanotolerance in Hybrid African Cattle [PDF]

Evolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT Integrative genomics combines data from different omics sources to link genotypes and phenotypes with the aim of unravelling biological networks and pathways that undergird complex traits, particularly with respect to disease. In this respect, integrative genomics, leveraging population and functional genomic data, can be employed to ...
