Genomic insights into the population structure and genetic diversity of Ugandan indigenous cattle. [PDF]

Anim Genet
Abstract Domestic cattle in Africa can be categorized as either taurine (Bos taurus) or indicine (Bos indicus) based on their domestication histories from the extinct aurochs (Bos primigenius). Close to 150 breeds of indigenous cattle are estimated to exist in Africa and have a complex mixture of B. taurus and B. indicus ancestries.

Evolutionary History of the Adult β-Globin Gene in Wild Sheep: First Sequences From the Argali (<i>Ovis ammon</i>) and the Urial (<i>Ovis vignei</i>). [PDF]

Ecol Evol
This study addresses a key gap in the understanding of molecular adaptation by providing the first complete adult β‐globin gene sequences for two ecologically significant wild sheep species, the Argali (Ovis ammon) and the Urial (Ovis vignei). ABSTRACT The β‐globin gene cluster is a key model for studying molecular adaptation and gene family evolution ...

Bovine gene polymorphisms related to fat deposition and meat tenderness

Genetics and Molecular Biology, 2009
Leptin, thyroglobulin and diacylglycerol O-acyltransferase play important roles in fat metabolism. Fat deposition has an influence on meat quality and consumers' choice.

Composição lipídica de carne bovina de grupos genéticos taurinos e zebuínos terminados em confinamento Lipid composition of meat from zebu and taurine cattle finished in confinement

Revista Brasileira de Zootecnia, 2009
O objetivo neste trabalho foi avaliar a composição em lipídeos totais, colesterol e ácidos graxos do músculo longissimus dorsi de bovinos Bos taurus (n=40) e Bos indicus (n=40) com 30 a 36 meses de idade e peso de carcaça entre 240 e 270 kg terminados em

Resistance to pH decline and slower calpain-1 autolysis are associated with higher energy availability early postmortem in Bos taurus indicus cattle.

Meat Science, 2019
Beef from Bos taurus indicus is associated with toughness compared to Bos taurus taurus, suggesting there is antagonism between adaptability to heat and beef quality.

Cattle phenotypes can disguise their maternal ancestry

BMC Genetics, 2017
Background Cattle are bred for, amongst other factors, specific traits, including parasite resistance and adaptation to climate. However, the influence and inheritance of mitochondrial DNA (mtDNA) are not usually considered in breeding programmes.

Mitochondrial DNA of Nellore and European x Nellore crossing cattle of high performance DNA mitocondrial de bovinos Nelore e cruzados Europeu x Nelore de alto desempenho

Pesquisa Agropecuária Brasileira, 2007
The objective of this work was to evaluate, through a polymorphism in the ND5 gene of the bovine mitochondrial DNA, the frequency of Bos taurus indicus mtDNA individuals in a sample of Nellore purebred origin animals (n = 69) and crossbred animals ...

Differences in Beef Quality between Angus (Bos taurus taurus) and Nellore (Bos taurus indicus) Cattle through a Proteomic and Phosphoproteomic Approach

PLoS ONE, 2017
Proteins are the major constituents of muscle and are key molecules regulating the metabolic changes during conversion of muscle to meat. Brazil is one of the largest exporters of beef and most Brazilian cattle are composed by zebu (Nellore) genotype ...
