Estratégias para antecipação da puberdade em novilhas Bos taurus indicus pré-púberes [PDF]

, 2018
A bovinocultura brasileira é uma das maiores potências mundiais na produção de proteína animal, porém é uma produção caracterizada por baixa eficiência quando comparada a países de primeiro mundo. O rebanho nacional é predominantemente Bos taurus indicus,

The Polled Locus Maps to BTA1 in a Bos indicus x Bos taurus Cross [PDF]

Journal of Heredity, 1996
Two hundred and nine reciprocal backcross and F2 progeny produced by embryo transfer from Angus (Bos taurus) and Brahman (Bos indicus) parents and their 60 parents and grandparents were utilized to localize the locus (POLL) responsible for the polled phenotype in a genetic map of bovine chromosome 1.

Long‐term changes in functional diversity and its implications for mammalian conservation and ecological restoration in a grassland ecosystem

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Paleontological data provide information on natural environments prior to human influence, which are useful for tracking changes in ecosystem functioning through time. During the Late Pleistocene, about 10% of terrestrial mammalian species were extinct in South America.

Alternative genotyping method for the single nucleotide polymorphism A2959G (AF159246) of the bovine CAST gene Método alternativo de genotipagem do polimorfismo de nucleotídeo único A2959G (AF159246) do gene CAST bovino

Pesquisa Agropecuária Brasileira, 2008
The objective of this work was to genotype the single nucleotide polymorphism (SNP) A2959G (AF159246) of bovine CAST gene by PCR-RFLP technique, and to report its use for the first time. For this, 147 Bos indicus and Bos taurus x Bos indicus animals were

Contrasting properties of predation and scavenging networks governed by megaherbivores in an African savannah

Journal of Animal Ecology, EarlyView.
For the first time, predation and scavenging networks are directly compared within a single ecosystem. Using an 8‐year dataset of African mammals, including megaherbivores, this study reveals distinct structural rules and body mass constraints, providing a scalable framework for studying consumer–resource dynamics and ecosystem function.

Morphological dimorphism in the Y chromosome of "pé-duro" cattle in the Brazilian State of Piauí

Genetics and Molecular Biology, 1999
"Pé-duro" (hard foot) is a rare breed of beef cattle of European (Bos taurus taurus) origin, originated in northern and northeastern Brazil. Y chromosome morphology, outer genital elements and other phenotypic characteristics were examined in 75 "pé-duro"

Genetic Relationships Between Residual Gain and Economically Important Traits in Nellore Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Sustainable beef production requires identifying animals with superior feed efficiency to reduce environmental impact and production costs. This study aimed to estimate heritability and genetic correlations between residual gain (RG) and growth, reproductive, carcass and feed efficiency traits in Nellore cattle.
