Book Description
Calves that gained more weight during preconditioning had larger REA but smaller REA/100kg values. As estimated Brahman percentage increased HCW and quality grade (QG) decreased. Differences in condition score resulted in heavier HCW for slightly thin and average condition calves when compared to slightly fleshy calves. Slightly thin calves had lower REA/100kg than average condition and slightly fleshy calves. Steers had heavier HCW than heifers and reported smaller REA/100kg values than heifers. Black cattle had lighter HCW than yellow, grey, and white cattle. Black and grey cattle had better QG than red and yellow cattle. Red and yellow cattle had similar QG, while white cattle were intermediate to all other colors and similar. Black cattle had a greater YG and smaller REA than all other colors evaluated. Black cattle had smaller REA/100kg values than yellow and grey calves but were similar to red and white cattle. Color pattern had no significant affect on any of the carcass traits measured indicating that cattle perform similarly for carcass characteristics regardless of color pattern. Shedding characteristics had no significant affect on any of the carcass traits measured in this study.

Book Description
Feed Efficiency in the Beef Industry provides a thorough and concise overview of feed efficiency in beef cattle. It frames the great importance of feed efficiency to the industry and details the latest findings of the many scientific disciplines that intersect and aim to improve efficient and sustainable production of nutritious beef. The vast majority of production costs are directly tied to feed. With increased demand for grains to feed a rapidly increasing world population and to supply a new demand for alternative fuels, feed costs continue to increase. In recent years, the negative environmental impacts of inefficient feeding have also been realized; as such feed efficiency is an important factor in both economic viability and environmental sustainability of cattle production. Feed Efficiency in the Beef Industry covers a broad range of topics ranging from economic evaluation of feed efficiency to the physiological and genetic bases of efficient conversion of feed to high quality beef. Chapters also look at how a fuller understanding of feed efficiency is leading to new selective breeding efforts to develop more efficient cattle. With wide-ranging coverage from leading international researchers, Feed Efficiency will be a valuable resource for producers who wish to understand the complexities, challenges, and opportunities to reduce their cost of production, for students studying the topic and for researchers and professionals working in the beef industry.
