Within the idea and objective of bringing together original studies dealing with the continuum aspects of meat, i.e., from farm to fork, this book grouped papers on the study of the nutritional, sensory, and technological aspects of carcass, muscle, meat, and meat-product qualities. This nook highlights a great part of the research activities in the field of meat science. A total of 14 original studies and one comprehensive review were edited within five main topics: (i) production systems and rearing practices, (ii) prediction of meat quality, (iii) statistical approaches for meat quality prediction/management, (iv) muscle biochemistry and proteomics techniques, and (v) consumer acceptability, development, and characterization of meat products.

A high moisture corn/soybean meal-based finishing ration was used to examine the effects of roughage source (corn silage, alfalfa hay), level of dietary roughage (8, 16, 24%), and ractopamine supplementation (none, Optaflexx) on growth performance, carcass traits, and beef quality for finishing 108 steers and 24 heifers (initial BW = 308 kg). Cattle were allocated by gender to 12 management regimen subclasses. Optaflexx (trade name for ractopamine hydrochloride) was fed over the last 28 d on feed with cattle marketed after common days on feed. Growth performance (ADG, feed intake, and feed efficiency) and carcass traits were assessed on an individual animal basis. A primal rib and semitendinosus (ST) muscle from each animal were processed at the University of Guelph Meat Laboratory for carcass and meat quality evaluations. Tenderness was determined using shear force assessment of product aged 7, 14, and 21 d. Average daily gains were similar (P > 0.27) across main effects while use of corn silage as the roughage source decreased (P 0.001) dry matter intake and improved (P 0.001) feed efficiency compared to feeding alfalfa hay. Roughage level and beta agonist supplementation did not affect (P 0.13) dry matter intake or feed efficiency. When the last 28 days on feed were examined, Optaflexx supplementation increased (P 0.001) weight change, ADG, and improved feed conversion, while DMI remained unchanged (P 0.373). Carcass traits including hot carcass weight, grade fat, longissimus muscle area, marbling, and body composition as assessed by rib dissection (% lean, fat, bone) were not affected (P 0.14) by roughage level, source, or use of Optaflexx. Fat partitioning and liver abscess scores were unaffected (P > 0.09) by source and level of roughage fed, and use of Optaflexx. Source and level of dietary roughage did not affect color (P > 0.21) or shear force (P > 0.20) values for longissimus (LM) and semitendinosus (ST) steaks. Lower DMI and better feed conversion can be achieved using corn silage as the roughage source, while inclusion of up to 24% roughage in finishing diets may not negatively impact gains, carcass characteristics or beef quality. Beef producers may be able to increase amounts of roughage in the diet to lower cost of production without compromising growth performance and carcass and meat quality.

This comprehensive work explores the demand, supply and variable consumer attitude toward a wide variety of unconventional and exotic animal species that are consumed in different parts of the world. Individual chapters focus on the consumption of horse meat, camel, buffalo, sheep, rabbit, wild boar, deer, goose, pheasant and exotic meats such as alligator, snake, frog and turtle. For each type of animal species, the carcass characteristics, physico-chemical properties and nutritional value of the meat are extensively outlined. The consumer preference, behavior and perception of each type of meat are also covered, with focus on important factors from sensory properties to psychological and marketing aspects. In promoting a better understanding of the complexities involved in consumer decision making, this book aims to improve the competitiveness of the meat industry through effective informational strategies that can increase consumer acceptance of more convenient, healthy and environmentally friendly meat choices. More than Beef, Pork and Chicken – The Production, Processing, and Quality Traits of Other Sources of Meat for Human Diet also focuses on the important role meat plays in the human diet and the evolution of the species. Beneficial factors such as protein, B complex vitamins, zinc, selenium and phosphorus are detailed. Negative factors are discussed as well, with issues such as fat and fatty acid content being addressed for each type of meat presented. In exploring the full range of nutritional benefits, consumer acceptance and carcass characteristics in a large quantity of different types of animal meats from all over the world, this book offers incredible value to researchers looking for a single source on unconventional meat processing.

Pork is the most widely produced meat in the world. To cover the demands of a fast growing population, new scientific knowledge in genetics, physiology and nutrition is generated, which contributes in a general increase of production performance. Production systems can be improved by constructing models which help to optimise use of the means of production and intensify production. In some regions where production intensity is high, concerns about environmental pollution are increasingly becoming a limiting factor. Consumers, and with them the retailer organisations, are voicing serious concerns about the production systems and especially the use of feed additives.In the context of the above, the question of the quality of pork becomes a relevant issue. A general view can only be obtained by taking all factors into consideration.The diverse aspects of pork quality were covered in the session on "Quality of Meat and Fat as Affected by Genetics and Nutrition" at the 50th annual meeting of the EAAP in Zurich. This publication presents the review presentations which give an overview from the different perspectives of meat quality and it's use in human nutrition: genetics, physiology, animal nutrition, meat consumption and human health and consumer concerns. In addition, 38 short communications provide up-to-date knowledge on the subject of quality from a European perspective.
