Book Description
To meet growing demand, the FAO has estimated that world poultry production needs to grow by 2-3% per year to 2030. Much of the increase in output already achieved has been as a result of improvements in commercial breeds combined with rearing in more intensive production systems. However, more intensive systems have increased the risk of transmission of animal diseases and zoonoses. Consumer expectations of sensory and nutritional quality have never been higher. At the same time consumers are more concerned about the environmental impact of poultry production as well as animal welfare. Drawing on an international range of expertise, this book reviews research on poultry breeding and nutrition. The first part of the book reviews how advances in genetics have impacted developments in breeding. Part 2 discusses ways of optimising poultry nutrition to ensure quality and sustainability in poultry meat production. Chapters review the use of feedstuffs and ingredients such as amino acids, enzymes and probiotics as well as feed formulation and safety. Achieving sustainable production of poultry meat Volume 2: Breeding and nutrition will be a standard reference for poultry and food scientists in universities, government and other research centres and companies involved in poultry production. It is accompanied by two further volumes which review safety, quality and sustainability as well as poultry health and welfare.

Book Description
Several experiments involving broilers and laying hens were conducted with the primary goal of evaluating the feeding value of Canola meal (CM) in both broiler and laying hen rations. A secondary goal was to study the growth response of broilers receiving higher concentrations of CM in their starter diets to supplements of protamone, arginine, methionine and/or zinc bacitracin. In the broiler experiments, satisfactory performance was obtained by feeding diets in which CM replaced up to 50% of soybean meal (SBM). However, growth and/or feed consumption and efficiency of feed utilization were adversely influenced by feeding CM at replacement levels higher than 50%. Protamone at 0.0025% of the diets containing CM at 50% and 100% reduced the enlarged thyroids of birds fed such diets to a size approaching that of controls, but a 0.005% level of protamone greatly reduced the size of the thyroids below that of birds fed the corn-SBM diet. No growth response was associated with the lower protamone dietary treatment, when a significant reduction in growth was observed to feeding the diets containing the higher protamone rate. Dietary supplements of arginine, methionine and zinc bacitracin did not appear to have a positive effect on performance of broiler chicks fed the starter diets at which CM substituted for higher levels of SBM. In all the broiler trials, there were no significant differences between the dietary treatments for the incidence of a leg abnormality condition, however, in experiment 4, when the chicks were fed the starter rations in which CM replaced 50% and 100% of SBM, a numerical increase in the occurrance of this condition was observed. In the laying hen experiment, CM which replaced up to 100% of SBM of the experimental rations, did not have any adverse effect on hen egg production, efficiency of feed utilization-, external and internal egg quality or final body weight. Fertility and hatchability of fertile eggs as well as dropping scores were also not significantly influenced by such dietary treatments. In both the broiler and laying hen trials, thyroid glands tended to be slightly enlarged with increasing levels of CM in the diets.

Book Description
Covering a variety of essential topics relating to commercial poultry nutrition and production—including feeding systems and poultry diets—this complete reference is ideal for professionals in the poultry-feed industries, veterinarians, nutritionists, and farm managers. Detailed and accessible, the guide analyzes commercial poultry production at a worldwide level and outlines the importance it holds for maintaining essential food supplies. With ingredient evaluations and diet formulations, the study's compressive models for feeding programs target a wide range of commercially prominent poultry, including laying hens, broiler chickens, turkeys, ducks, geese, and game birds, among others.

Book Description
Current growth in global aquaculture is paralleled by an equally significant increase in companies involved in aquafeed manufacture. Latest information has identified over 1,200 such companies, not including those organizations in production of a variety of other materials, i. e. , vitamins, minerals, and therapeutics, all used in varying degrees in proper feed formulation. Aquaculture industries raising particular economically valued species, i. e. , penaeid shrimps and salmonids, are making major demands on feed ingredients, while relatively new industries, such as til apia farming, portent a significant acceleration in demand for properly formulated aquafeeds by the end of the present decade and into the next century. As requirements for aquafeeds increases, shortages are anticipated in various ingredients, especially widely used proteinaceous resources such as fish meal. A variety of other proteinaceous commodities are being considered as partial or complete replacement for fish meal, especially use of plant protein sources such as soybean meal. In the past five years, vegetable protein meal production has increased 10% while fish meal production has dropped over 50%, since 1989, largely attributed to overfishing and serious decline in wild stock. Throughout fisheries processing industries, traditional concepts as "waste" have given way to more prudent approaches, emphasizing total by-product recovery. Feed costs are a major consideration in aquaculture where in some groups, i. e. , salmonids, high protein-containing feeds using quality fish meal, can account for as much as 40 to 60% of production costs.

Book Description
Means of improving the quality of CM for poultry, including breeding for low-fiber canola and the use of exogenous enzymes, have been proposed. The objectives of the current study were: (1) To evaluate the chemical and nutritive composition of new yellow-seeded B. napus and B. juncea canola, (2) To investigate the effect of canola type and enzyme supplementation on AMEn and SID of amino acids, and growth performance of broiler chickens, (3) To explore the new carbohydrase enzymes for their ability to depolymerize NSP of CM in vitro, and (4) To evaluate the effect of new enzyme combinations in vivo with broiler chickens. In comparison with the conventional meal, yellow-seeded B. napus and B. juncea contained more crude protein, more sucrose, and less dietary fiber. The AMEn and SID amino acid values for yellow-seeded B. napus, B. juncea canola, and the conventional black-seeded B. napus were 1865, 2092 and 1902 kcal/kg DM, and 82.5, 83.2, and 81.8%, respectively. Enzyme addition resulted in a more pronounced effect on the AMEn content of B. juncea meal. When birds were fed diets containing 15% CM, BWG averaged 2.32, 2.30, 2.19, and 2.31 kg for the SBM-based Control, black and yellow B. napus, and B. juncea meals, respectively. A lower (P
