The objective of this study was to compare carcass characteristics of a newly introduced breed, the Waguli (Wagyu x Tuli), with the carcass characteristics of the Brahman breed. Brahman cattle are used extensively in the Southwest of the United States because of their tolerance to adverse environmental conditions. However, Brahman carcasses are discounted according to the height of their humps ...

Genetic parameters were estimated for scrotal circumference (SC; n=287), age at puberty in heifers (AP; n=292), and hip height in both sexes (HH; n=684) for Brahman cattle born from 1984 to 1994 at the Subtropical Agricultural Research Station, Brooksville, Florida. Age at puberty was defined as the age (days) at first detected ovulatory estrus. Measurements of SC and HH were taken at 18 mo of ...

Upazila Livestock Office, Chirirbandar, Dinajpur, Bangladesh A beef breed development project was carried out in the Department of Livestock Services (DLS) in 2009 in selected areas of Bangladesh. Under this project, semen of Brahman bulls were imported from the USA and used to inseminate indigenous cows to produce graded calves. The present study was undertaken to select graded Brahman bulls o...

OBJECTIVE To determine whether known loss-of-function alleles of the acidic α-glucosidase gene (GAA) are present in the Droughtmaster breed and, if so, whether the clinical signs and pathology of generalised glycogenosis (Pompe's disease) previously reported in other affected cattle are also seen in homozygous Droughtmasters. DESIGN Existing genomic and other diagnostic tests developed for ge...

New sites developed for improved cattle testing are described in this paper. Two separate trials were conducted on a total of 379 Friesian and Brahman cows. In the first test, conducted with an early version of the RENCO PREG-ALERT®(2) modified or cattle testing, the accuracy rate was 96.6% for non pregnant cows, and 90.4% for cows determined to be 5 weeks to 8 months pregnant by rectal palpati...

Pregnancy rate, calf survival rate to weaning and calf age at weaning of several types of crossbred cows (2/3 or more Brahman) were compared to those of straightbred Brahman and Angus cows over a 1 2 9 period at Subtropical Agricultural Research Station near Brooksville, FL. The purpose of this study was to determine the relative importance of additive vs nonadditive genetic effects on reproduc...

We evaluated the relevance of the BovineHD Illumina SNP chip with respect to genes involved in epigenetic processes. Genotypes for 729,068 SNP on two tropical cattle breeds of Australia were used: Brahman (n = 2112) and Tropical Composite (n = 2550). We used data mining approaches to compile a list of bovine protein-coding genes involved in epigenetic processes. These genes represent 9 function...

The objective of this study was to evaluate the effect intronic single nucleotide polymorphisms (SNP) on temperament traits in a Brahman cattle population. SNP located CACNG4, EXOC4, NRXN3, and SLC9A4 candidate genes were genotyped 250 animals with records exit velocity, pen score, score. Rs3423464051:G>A CACNG4 gene associated velocity An silico analysis five showed that alternative alleles CA...

The objective of this study was to quantify the genetic diversity among breeds under evaluation for tropical adaptability traits that affect the performance of beef cattle at the USDA/ARS SubTropical Agricultural Research Station (STARS) near Brooksville, FL, USA. Twenty-six microsatellite loci were used to estimate parameters of genetic diversity among the breeds American Brahman, Angus, Senep...
