The use of non-penetrating pre-slaughter stunning (NPPSS) in ruminants remains a contentious issue Indonesia since it is thought to interfere with the bleeding. This paper evaluated bleeding time (BT), incidence false aneurysm (FA), and factors influencing these parameters 460 NPPSS 50 non-NPPSS slaughters Indonesia. In this research, bodyweight, neck skin fold, sex, incisors condition, stunner...

Genotyping of the South African, registered, Brahman cattle population for the 470del20 mutation in the CHRNE gene causing congenital myasthenic syndrome (CMS) was carried out in 1,453 animals. Overall prevalence of carriers was 0.97% (0.50 to 1.68%, 95% confidence interval). Carrier prevalence among breeding bulls in 2004 was 1.22% (0.65 to 2.15%, 95% confidence interval), and had not changed ...

Reproductive data were collected on 4,595 cow exposures and subsequent calvings over four generations in a rotational crossbreeding study involving Angus, Brahman, Charolais and Hereford breeds. Direct and maternal additive (Ig and Mg) and nonadditive (Ih and Mh) genetic effects were estimated for calving rate, calf survival, weaning rate, calving assistance and calf birth date. Genetic effects...

Mature weight and rate of maturing were estimated in 177 Angus, Brahman, and reciprocal-cross cows grazing bermudagrass or endophyte-infected tall fescue over a 4-yr period to evaluate genotype x environment interactions. Data were collected every 28 d until cows were approximately 18 mo of age and then at prebreeding, postcalving, and weaning of calf. All cows with weight data to at least 42 m...

A trial was conducted to evaluate the ability of a prostaglandin analog, Luprostiol (LP), to synchronize estrus in Brahman cows and heifers. Animals were injected with either 0, 3.75, 7.5, 15 or 30 mg LP or 500 micrograms cloprostenol (CLP) on d 8 or 9 after estrus (d 0). All concentrations of LP (greater than 0 mg) and CLP caused luteolysis in cows and heifers, as indicated by a decline (P les...

The benefits of early weaning during instances of environmental strain, usually witnessed by a shortage of summer forage, has been understood and practiced for many years. However, the use of early weaning as a normal, annual management practice for beef cows is not common. Our interest in the topic originated from the common production practice in the Southeast, which allowed heifers to develo...

Rumen microbial populations were measured in Brahman-cross steers that were relocated from spear grass (Heteropogon contortus) dominant pastures in northern Queensland to buffel grass (Cenchrus ciliasis) dominant pastures in central Queensland, to assess whether aspects of rumen function may contribute to the sometimes reported depressed growth rates following relocation. Nine genera of ciliate...
