Sexual development in early- and late-maturing Bos indicus and Bos indicus × Bos taurus crossbred bulls in Brazil [PDF]

Theriogenology, 2004
Two experiments were conducted to evaluate sexual development in early- and late-maturing Nelore (Bos indicus) and Canchim (3/8 Bos indicus x 5/8 Bos taurus crossbred) bulls and to determine predictors of sexual precocity, and pubertal and maturity status. In Experiment 1, 12 Nelore bulls where examined from 300 to 900 days of age.

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.

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

Y chromosome variants in cattle Bos taurus and Bos indicus [PDF]

Genetics Selection Evolution, 1982
Summary It is shown that comparison of the size of the Y chromosome between individuals may be made as reliably by computation of measurement relative to the X chromosome as by proportionation relative to the genome in the cell. By either method agreement was found with previous studies : first in placing the Y in the size range, for the cattle ...

Whole-genome sequencing reveals insights into the adaptation of French Charolais cattle to Cuban tropical conditions

Genetics Selection Evolution, 2021
Background In the early 20th century, Cuban farmers imported Charolais cattle (CHFR) directly from France. These animals are now known as Chacuba (CHCU) and have become adapted to the rough environmental tropical conditions in Cuba.

Genetic analysis of Thai cattle reveals a Southeast Asian indicine ancestry [PDF]

PeerJ, 2015
Cattle commonly raised in Thailand have characteristics of Bos indicus (zebu). We do not know when or how cattle domestication in Thailand occurred, and so questions remain regarding their origins and relationships to other breeds.
