Download or read book Commercial Chicken Meat and Egg Production written by Donald D. Bell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Commercial Chicken Meat and Egg Production is the 5th edition of a highly successful book first authored by Dr. Mack O. North in 1972, updated in 1978 and 1984. The 4th edition was co-authored with Donald D. Bell in 1990. The book has achieved international success as a reference for students and commercial poultry and egg producers in every major poultry producing country in the world. The 5th edition is essential reading for students preparing to enter the poultry industry, for owners and managers of existing poultry companies and for scientists who need a major source of scientifically based material on poultry management. In earlier editions, the authors emphasized the chicken and its management. The 5th edition, with the emphasis shifted to the commercial business of managing poultry, contains over 75% new material. The contributions of 14 new authors make this new edition the most comprehensive such book available. Since extensive references are made to the international aspects of poultry management, all data are presented in both the Imperial and Metric form. Over 300 tables and 250 photos and figures support 62 chapters of text. New areas include processing of poultry and eggs with thorough discussions of food safety and further processing. The business of maintaining poultry is discussed in chapters on economics, model production firms, the use of computers, and record keeping. Updated topics include: breeders and hatchery operations; broiler and layer flock management; replacement programs and management of replacements; nutrition; and flock health. New chapters address flock behavior, ventilation, waste management, egg quality and egg breakage. Other new features include a list of more than 400 references and a Master List of the tables, figures, manufacturers of equipment and supplies, research institutions, books and periodicals, breeders, and trade associations. Commercial growers will find the tables of data of particular interest; scientists will be able to utilize the extensive references and to relate their areas of interest to the commercial industry's applications; and students will find that the division of the book into 11 distinct sections, with multiple chapters in each, will make the text especially useful.

Book excerpt: Excerpt from Some Factors Affecting the Weight, Composition and Hatchability of Hen Eggs The tests indicate that when fowls are fed too scantily the fertility of the eggs will be low, but those which are fertile seem to hatch practically as well as the fertile eggs laid by the fowls fed heavily. Hatch 5 indicates that after fowls have been laying heavily for a considerable length of time their eggs are less fertile and do not hatch so well as eggs laid by fowls which are just reaching or have reached their maximum egg production for the season. There seems to be no great difference in the vigor of the chicks from the two lots of fowls, although what difference there is seems to be in favor of the chicks from the fowls fed scantily, ex cept in the case of the last hatch.

This book was released on 2017-10-17 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Data on Certain Factors Influencing the Fertility and Hatching of Eggs There is a rather common belief that when hatching eggs run low in fertility the fault is chiefly or entirely in the male bird which is with the flock. For some reason which is difficult to understand very little influence is attributed in the popular mind to the females in causing poor results of this kind, the belief rather being that the male bird has an almost exclusive influence in determining fertility of eggs. It seems somewhat remarkable that this notion of the predominant influence of the male bird in determining the fertility of eggs among poultry should be so widespread, in view of the fact that the popular belief with reference to other domestic animals is exactly the opposite. For example, in cattle and horse breeding the fail ure of the female to become pregnant (the equivalent in part of the fertilization of the egg in poultry) is commonly attrib uted to some defect in the female rather than in the male. The standpoint which the known facts of biology lead one to take is that in all bisexual animals the influence of the two sexes is in general equal in determining whether any given egg shall or Shall not be fertilized. That is to say, there is on general grounds every reason to suppose that the infertility of eggs is as likely to be due to a defect of the female as to a defect of the male and vice versa. It seems desirable to determine with some precision whether this general statement is true for poultry or not. When the average fertility for a flock of hens runs low what proportion of this low fertility is to be attributed to the poor breeding performance of the hens and what proportion to the male birds? The practical importance of the question is obvious. If the man who is selling eggs for hatching can learn that one particular hen, for example, in his flock never pro duces a fertile egg, it will be greatly to the advantage of his trade to eliminate that bird from those which are producing his hatching eggs. In order to bring out with completeness and precision the comparative influence of male and female birds on the fertility of eggs Tables VII and VIII have been prepared. These tables Show for each breeding pen the following facts: (i) The band number of the cockerel which was placed in that pen.
