The ability to maintain normal temperatures during heat stress is an important attribute for cattle in the subtropics and tropics. Previous studies have shown that Senepol cattle and their crosses with Holstein, Charolais and Angus animals are as heat tolerant as Brahman cattle. This has been attributed to the slick hair coat of Senepol cattle, which is thought to be controlled by a single domi...

GENERAL REPRODUCTIVE TRAITS The Brahman is a Bos indicus breed which was developed in the Gulf Coast states of the United States (Phillips, 1963; Yturria, 1973). The adaptive traits which specifically suit the Brahman and Brahman based breeds for production in temperate, subtropical or tropical areas include: tolerance of internal and external parasites; tolerance of high solar energy, ambient ...

Abstract This paper examines the challenges restricting commercialization of cattle across Nguni Cattle Project beneficiaries in South Africa. Data were collected from one hundred and twenty (120) using a structured questionnaire six district municipalities Eastern Cape Province. Results revealed that majority males, above 60 years old, have received formal training livestock farming. Most rear...

When the livestock sector is considered an essential role in farmers' livelihood, and local breeds are still critical component of animal breeding Laos. Thus, there a need to review previous, current situation prospects for Laos' production. It aimed study different traits among existing dominant improved (cattle, pig, goat) more in-depth on sector's previous evolving prospects. Our findings re...

Effects of ractopamine hydrochloride (RAC) supplementation on growth performance and carcass characteristics of feedlot steers differing in biological type were investigated using British, Continental crossbred, and Brahman crossbred calf-fed steers (n = 420). Steers of each type were weighed at reimplantation [British, mean BW = 375 kg (SD = 38 kg); Continental crossbred, mean BW = 379 kg (SD ...

Whole genome association studies have been increasingly used for QTL discovery. Analyses can performed using single marker (for example, single-nucleotide polymorphism, SNP) regression, but have also evolved to multiple marker (SNPs) regression to facilitate genomic selection. A major area of importance to the Northern Australian beef industry is female reproductive rate; specifically the numbe...

This research developed two real-time PCR assays, employing high-resolution melt and allele-specific analysis to accurately genotype the F94L mutation in cattle. This mutation (g.433C > A) in the growth differentiation factor 8 or myostatin gene has recently been shown to be functionally associated with increased muscle mass and carcass yield in cattle. The F94L mutation is not, like other myos...

The aim of this experiment was to determine CH4 production and energy partition for a range of diets fed to Bos indicus cattle. Six Brahman cattle were fed on three different diets in a replicated Latin square experiment over three periods. The diets were (1) long-chopped Angleton grass (Dicanthium aristatum) hay ad libitum (DM digestibility (DMD) 41 (SE 2)%; 4 g N/kg), (2) long-chopped Rhodes ...
