OBJECTIVE This study was aimed at evaluating effects of cattle breed resources and alternative mixed-feeding practices on meat productivity and emission intensities from household farming systems (HFS) in Daklak Province, Vietnam. METHODS Records from Local Yellow×Red Sindhi (Bos indicus; Lai Sind) and 1/2 Limousin, 1/2 Drought Master, and 1/2 Red Angus cattle during the growth (0 to 21 month...

Heterosis and breed differences were estimated for milk yield traits, somatic cell score (SCS), and productive life (PL), a measure of longevity. Yield trait data were from 10,442 crossbreds and 140,421 purebreds born since 1990 in 572 herds. Productive life data were from 41,131 crossbred cows and 726,344 purebreds born from 1960 through 1991. The model for test-day yields and SCS included eff...

AIM The study was undertaken to study acute phase response based on acute phase proteins (APPs) such as C-reactive protein (CRP), haptoglobin (Hp), serum amyloid A (SAA), and fibrinogen in lame crossbred dairy cattle. MATERIALS AND METHODS Lame animals (n=30) were selected within 3-7 days of being noticed as lame by the farm veterinarian, from a local dairy farm in southeast Ludhiana over a p...

The purpose of this study was to determine effects of feeding canola and soybean products as protein supplements on fatty acid composition of adipose tissue and muscle of slaughter bulls and steers and on fatty acid composition of kidney and liver total lipids of bulls. Products included canola meal (CM), extruded canola (EC, full-fat), ground canola (GC, full-fat), soybean meal (SBM), and extr...

Campylobacter is a prevalent zoonotic bacterial pathogen found in various food animals such as cattle, sheep, goats, and poultry. The increasing production of crossbred cattle Bangladesh aimed at meeting the demand for animal protein. However, this trend also poses public health risks associated with emergence cattle-specific Campylobacter. It probable that there an increased probability transm...

the aim of the present study was to screen the genotype profile of bovine kappa-casein gene among frieswal (hf × sahiwal) crossbred cattle developed in india. a total number of two hundred frieswal cows were evaluated for hinfi rflp based genotyping of kappa-casein gene. we observed that only two genotypes (aa and ab) exist among the studied population with the genotype frequency of 0.58 (n=117...

Chromosomal regions harboring variation affecting cattle birth weight and BW gain to 1 yr of age were identified by marker association using the highly parallel BovineSNP50 BeadChip (50K) assay composed of 54,001 individual SNP. Genotypes were obtained from progeny (F(1); 590 steers) and 2-, 3-, and 4-breed cross grandprogeny (F(1)(2) = F(1) x F(1); 1,306 steers and 707 females) of 150 AI sires...

Four months back calved crossbred dairy cow had history of coffee coloured urine. Blood smear and Blood samples of this cow were collected on the day of acute stage of infection and then 15th day of post treatment for haematological parameters. Based on the clinical pathonomonic symptom (coffee coloured urine) and blood smear examination presence of Babesia bigemina organisms the disease was di...

Body linear measurements, and specifically heart girth (HG), have been shown to be useful predictors of cattle liveweight. To test the accuracy of body linear measurements for predicting liveweight, crossbred dairy cattle of different genotypes were measured and weighed. A total of 352 mature cows and 100 heifers were weighed using an electronic weighing scale and measurements of HG, body lengt...

Aim: The aim of this study was to investigate the incidence of bovine tuberculosis (BTB), an old chronic disease having zoonotic potential, covering four districts in Gangetic delta region of West Bengal, India, and to find the prevalence in organized as well as backyard herds and variation in relation to their age, sex, and breeds. Methods: The incidence of BTB in exotic and indigenous breeds ...
