Book Description
Three main factors affect the quality and composition of meat in farm animals. Production conditions determine the composition of the meat, while marketing and postmortem periods have a major bearing on the visual appearance and ultimate eating experience for the consumer. It is often difficult to compare research results from different countries since meat quality is assessed by a wide variety of procedures. Quality and Grading of Carcasses of Meat Animals reviews the development of commercial grading or classification schemes on a world-wide basis, and it provides a broad outline of the most common subjective and objective procedures for the assessment of meat quality. The book provides reviews on: Ante- and post-mortem effects on meat quality Reducing fatness in meat animals Prediction of carcass composition and meat quality World carcass and grading systems Electronic identification of animals

Book Description
One of the biggest challenges faced by meat producers today is the requirement to improve the quality of meat while maintaining focus on efficiency and higher yields. Numerous studies have shown that consumers are willing to pay premiums for meat products with guaranteed eating quality. This book examines the complicated multistep process of produc

Book Description
An investigation was undertaken to evaluate live performance, carcass characteristics and meat quality traits of 183 progeny test steers sired by 10 Hereford, 3 Charolais, 1 Holstein and 1 Angus sires and from grade Hereford dams. An additional group of 10 steers were Hereford sired, from Holstein X Hereford dams. Disproportionate data necessitated an analysis of variance using a nested or hierarchial classification. Components of variance were estimated for groups (feeding method, ranch and breed), sires within groups and progeny within sires. Heritabilities were calculated from paternal half sib correlations. Intercorrelations among 42 performance and carcass traits were calculated. Sire variance and heritability estimates were high for feedlot average daily gain (ADG) for the calves which were fed to market condition rapidly (fed-calf program) but were low for those carried on a lower plane of nutrition for 174 days followed by full feeding to market condition (fed-yearling program). High heritabilities were obtained for lifetime average daily gain (LADG) under both programs and would therefore seem to be a more useful measure of gainability than feedlot ADG. Dressing per cent and per cent kidney fat showed significant sire differences with heritability estimates of 78 per cent and 45 per cent respectively. Measures of fat cover over the rib-eye had low heritabilities which were probably influenced by marketing at an appraised constant finish. Fat cover per cwt. had a higher heritability at 46 per cent and would therefore be a preferred measure for progeny testing purposes. With a heritability of 89 per cent, rib-eye area per cwt. was superior to rib-eye area, rib-eye depth and per cent separable lean in a rib core, for detecting sire progeny differences in leanness. Rib-eye depth proved to be of no value in this regard. No significant group or sire within group differences were obtained for retail yield although the heritability estimate was 29 per cent for this trait. Marketing at an appraised constant finish may have masked sire differences for this measure. Sire progeny groups did not differ in ether extract of longissimus dorsi muscle, a measure of marbling. Sire progeny group differences were easily detected for tenderness of the longissimus dorsi muscle. A similar result was obtained for muscle fiber diameter. Average fat cover was the best individual predictor of retail yield accounting for 29 per cent of its variation. Estimating yield by the U.S.D.A. formula of Murphey et al. (1960) was no more accurate as a predictor than fat cover alone. Other possible predictors of retail yield along with their coefficients of determination were; per cent trimmed chuck (17 per cent), per cent trimmed round (15 per cent), per cent separable lean in a rib core (11 per cent) and rib-eye area per cwt. (6 per cent). No significant relationships were found between measures of gain and retail yield or measures of quality and retail yield.

Book Description
Animal Agriculture: Sustainability, Challenges and Innovations discusses the land-based production of high-quality protein by livestock and poultry and how it plays an important role in improving human nutrition, growth and health. With exponential growth of the global population and marked rises in meat consumption per capita, demands for animal-source protein are expected to increase 72% between 2013 and 2050. This raises concerns about the sustainability and environmental impacts of animal agriculture. An attractive solution to meeting increasing needs for animal products and mitigating undesirable effects of agricultural practices is to enhance the efficiency of animal growth, reproduction, and lactation. Currently, there is no resource that offers specific knowledge of both animal science and technology, including biotechnology for the sustainability of animal agriculture for the expanding global demand of food in the face of diminishing resources. This book fills that gap, giving readers all the necessary information on important issues facing modern animal agriculture, namely its sustainability, challenges and innovative solutions. - Integrates new knowledge in animal breeding, biotechnology, nutrition, reproduction and management - Addresses the urgent issue of sustainability in modern animal agriculture - Provides practical solutions on how to solve the current and future problems that face animal agriculture worldwide

Book Description
The second edition of Dennis Averys 1995 seminal work, Saving the Planet Through Pesticides and Plastics provides the flip side to environmentalist cries of spiraling cancer rates, rising global temperatures and decreasing rainforest acreage. Thoroughly updated and re-written with new information and data, Averys controversial book shows how agricultural technology can save the planet for both people and wildlife.
