Genetic polymorphism of Pit-1|HinfI gene in Grati-Ongole Grade cattle at Indonesian Beef Cattle Research Station

Beef Cattle Research Update

Factors Affecting Cattle during Long-Haul Transport in North America Canadian researchers identified and quantified several factors affecting weight loss (shrink) and animal welfare in cattle during commercial long-haul transport (≥ 249 miles). This study documented current commercial practices in Alberta, Canada through surveys delivered to truck drives (6,152 journeys transporting 290,886 ani...

Beef Cattle Research Update

Effects of Body Condition Recent University of Arkansas research determined the interactive effects of forage environment and body condition on the calving rate of beef cows. multiparous beef cows (1/4 to 3/8 Brahman) were managed to achieve marginal (4.7) or good (6.6) body condition scores (BCS) over approximately 5 months before the initiation of the breeding season. growth, endophyte acres ...

Genetic Improvement of Reproduction in Beef Cattle

Reproduction is a key profit driver in beef cattle production systems around the world. However genetic evaluation for reproduction traits is generally limited or non-existent. This is likely a function of low levels of recording reproduction traits, and low heritabilities. Traditional BLUP based genetic evaluations have been used effectively in beef for generating estimated breeding values and...

Genetic polymorphism of the kappa-casein gene in Brazilian cattle.

Frequencies of kappa-casein gene alleles were determined in 1316 animals from the Brazilian Bos indicus genetic groups (Sindhi cows, Gyr sires, Gyr cows, Guzerat sires, Guzerat cows, Nellore sires, and Gyr x Holstein crossbreds) by means of polymerase chain reaction-restriction fragment length polymorphism analysis using two independent restriction nucleases (Hinf I and HaeIII). The genotyping ...
