Book excerpt: This book reviews the biological science and background to breeding meat poultry, specifically broiler, turkey and duck. These commercial birds have been changed by genetic selection to such an extent that they are substantially different from traditional breeds and laying hens. Covering science, management and husbandry systems, this book is an essential reference for researchers and students in animal science, as well as technical staff of breeding companies and poultry meat producers. Part of the Poultry Science Symposium Series.

Available in PDF, EPUB and Kindle. Book excerpt: This classic reference for poultry nutrition has been updated for the first time since 1984. The chapter on general considerations concerning individual nutrients and water has been greatly expanded and includes, for the first time, equations for predicting the energy value of individual feed ingredients from their proximate composition. This volume includes the latest information on the nutrient requirements of meat- and egg-type chickens, incorporating data on brown-egg strains, turkeys, geese, ducks, pheasants, Japanese quail, and Bobwhite quail. This publication also contains new appendix tables that document in detail the scientific information used to derive the nutrient requirements appearing in the summary tables for each species of bird.

This book was released on 2020 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last 60 plus years, broiler breeders have been under an incredible amount of genetic pressure. This genetic pressure comes from the continually increasing consumer demand for poultry products. The objective of this dissertation is to understand the effects of different nutritional and management practices on broiler breeder's performance. The first series of experiments investigate the impact of broilerization on hen and early progeny performance. Broilerization is a process only used by genetic companies. The results from these experiments showed the adverse effects of broilerization on chick quality and hen performance. Follow up trials were performed to determine the benefits of feeding different dietary oil sources to broilerized hens; additionally, their effects on chick quality and hen performance over a 30-week production period. Broilerized hens were reared as recommended for the industry, and at 5 % production, they were fed diets containing either poultry fat, corn oil, or canola oil as a dietary fat source. Different traits were measured, and the positive effects of corn and canola oil were shown as far as improvement of chick quality and eggs per hen housed. These dietary oil sources were also beneficial for parent stock hens (not broilerized), improving overall hen performance and chick quality at different hen ages. The second series of experiments take a more in-depth look into the effects of varying rearing methods on the performance of parent stock hens. Results from this study showed the efficiency of rearing hens on every day versus a skip a day feeding method. Fatty acids and carbohydrate metabolism play an essential role in the improvement of chick quality. The last few experiments of this dissertation show the effects of hen age on hen performance and chick quality. Results from the two previous studies provide an insight into the possible reason why younger hens and older hens have more challenges producing high-quality chicks. Overall, results from these studies allow for a deeper understanding of the effect of different nutritional and management strategies on the performance of the current broiler breeder.
Download or read book Effect of Dietary Phosphorus and Enzyme Levels on Reproduction in Turkey Breeder Hens written by and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous work has demonstrated that the P requirement for turkey breeder hens has not been adequately determined. It is becoming apparent that there are distinctive P requirements of turkey breeder hens compared to poults and growing birds. Therefore, the objective of this study was to provide additional information regarding P requirement and use of phytase in turkey breeder hen diets. An experiment was conducted to determine the effect of dietary phosphorus (P) levels and phytase enzyme levels on turkey breeder hen productivity from 31 to 62 weeks of age (WOA). Four hundred and eighty turkey breeder hens were reared in a curtain-sided house with 48 pens (10 birds per pen; 8 pens per treatment) at 31 WOA. Hens were fed a breeder ration with treatments as follows: high P (HP), available P=0.55%; high P + enzyme (HP+E), medium P (MP), available P=0.35%; medium P + enzyme (MP+E), low P (LP), available P=0.17%; and low P + enzyme (LP+E). The phytase enzyme product used (AllzymeTM Phytase, Alltech, Inc., Nicholasville, KY 40356) is derived from Aspergillus niger and contained 11.27 PTU/g. Feed and water were available ad libitum for a 28-week reproductive period. Diets were fed in mash form. All hens were photostimulated in January (31 WOA) with 15.5 h of light/day. Individual bird body weight and feed consumption, by pen, were determined at monthly intervals from 31 WOA to 62 WOA. Hens were inseminated weekly with pooled semen from same strain breeder males. Hens were observed for biweekly reproductive and hatchability performance for 28 weeks of lay (WOL) and recorded on a pen basis. The following parameters were measured: egg production, fertility, hatchability of all eggs, hatch of fertile, initial egg weight, % egg weight loss, conductance, and embryonic mortality. Egg weight, shell thickness, albumen P and yolk P were measured monthly. At the end of the study P concentration was measured in plasma, tibia, fecal P and water-soluble fecal P. There were no consistent.

This book was released on 2023-02-28 with total page 674 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food production, particularly animal protein production, is changing. While productivity, efficiency and food quality continue to be of vital importance, there is increasing pressure on producers to prioritize sustainability and animal health and welfare as well minimize food waste. Optimizing vitamin nutrition can help make animal production more sustainable by optimizing animal health and welfare and animal performance and food quality, while reducing food waste. Optimum Vitamin Nutrition for More Sustainable Poultry Farming contains concise, up-to-date information on vitamin nutrition for poultry. This book, which follows the authoritative Optimum Vitamin Nutrition in the Production of Quality Animal Foods (5m Books, 2013), is a reference for research and extension specialists who need the most current, research-based information on vitamins in poultry. This book is first in a series of books covering Optimum Vitamin Nutrition in swine, ruminants and aquaculture.
