Download or read book Energy Metabolism in Farm Animals written by M.W. Verstegen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal production systems have changed dramatically over the last two decades. Knowledge of energy metabolism and environmental physio logy has increased as appears from many textbooks on these disciplines. The contents of the symposia on energy metabolism of farm animals show this and they have initially focussed on feed evaluation and later on com parative aspects of energy metabolism. They show part of the progress being made. Application of knowledge of energy metabolism for animals has a long history since Lavoisier. In addition to this, studies about the environ mental requirements of animals have shown that we are still far from ac curate assessment of these requirements in terms of nutrients and ener gy. I n model studies on energy metabolism researchers have recognized the interaction between the environment and the energy requirements of animals. Estimation of energy requirements has been done in physiolo gical, physical and behavioural studies. The impact of conditions as en countered by animals in various production systems has been approached from different viewpoints related to these different disciplines. In addi tion, various kinds of infections (bacterial, parasitic: subclinical, clini cal) have been evaluated only recently with regard to their effect on pro tein and/or energy metabolism and thus on production. People working in the field of feed evaluation have defined how che mical and physical properties of nutrition infiuence energy to be derived for maintenance and production.

Download or read book The Effect of Early Incubation Temperature and Late Incubation Conditions on Embryonic Development and Subsequent Broiler Performance written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Six experiments were conducted to evaluate the effects of early and late incubation temperatures and hatching basket ventilation on embryonic development and early broiler performance. Eggs were exposed to a constant incubation air temperature of 37.6 & deg;C (99.7 & deg;F) from E 0-17 in Experiment 1 while Experiments 2-5 employed an incubation temperature profile that had an initial dry bulb set point of 38.1 & deg;C (100.5 & deg;F), which was gradually decreased to 37.2 & deg;C (99.0 & deg;F). Experiment 6 exposed eggs to either an Early Hot treatment (EH) that had a short initial air temperature of 38.9 & deg;C (102 & deg;F) followed by 38.1 & deg;C (100.5 & deg;F) to E 3 or an Early Cool treatment (EC) of 36.9 & deg;C (98.5 & deg;F) to E 3. Experiments 1-4 used an average air temperature of 38.1 & deg;C (100.5 & deg;F) during the late incubation period, while Experiments 5 and 6 added a late temperature treatment of approximately 35 & deg;C (95.0 & deg;F) (LC) in addition to 38.1 & deg;C (100.5 & deg;F; LH). Hatching baskets were modified to create ventilation treatments in order to examine the effect of air flow path on embryonic development and used varyingly throughout Experiments 1-6. Two treatments were designed to restricted air flow through the hatching basket by blocking air flow through either the top half of the basket (TT) or the bottom half of the basket (BT). Other hatching baskets remained unaltered to serve as a control group (CN). Experiments 1-2 included all three types but just the TT and BT treatments were used in Experiment 3. Experiments 4-6 used the TT and CN treatments in addition to the baskets at either low density (LD) or high density (HD). The TT treatment produced chicks with significantly less relative yolk sac in Experiment 1, but differences between ventilation treatments did not occur in other experiments. At E 15 of incubation, embryos from the EC treatment in Experiment 6 exhibited a decreased embryo weight and fluid (yolk and albumen) absorption. The LC treatmen.
Download or read book Egg Incubation written by D. Charles Deeming and published by Cambridge University Press. This book was released on 2004-11-11 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews comprehensively incubation effects on embryonic development in birds and reptiles and presents the first ever synthesis of data from these two vertebrate classes. The book is in three parts. The first deals with the structure, shape and function of eggs. The second examines the effects of the four main parameters on the process of incubation: temperature, water relations, respiratory gas exchange, and turning. The third section deals with early embryonic development and the methods used to investigate and manipulate the embryo. Further chapters deal with aestivation, megapodes and oviparity. International experts in each field have contributed to this extensively referenced volume and it will be of great interest not only to research biologists, but also to bird and reptile breeders, whether in commercial organisations or in zoos.

Download or read book Biotechnology in Animal Husbandry written by R. Renaville and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal biotechnology is a broad umbrella encompassing the polarities of fundamental and applied research including molecular modelling, molecular and quantitative genetics, gene manipulation, development of diagnostics and vaccines and manipulation of tissue or digestion metabolism by growth promoters. Although animal biotechnology in the broadest sense is not new, what is new is the level of complexity and precision involved in scientists' current ability to manipulate living organisms. This new book sets out to show that the important ideas in animal biotechnology are exciting and relevant to everyday experience. It represents an important update of the literature for research workers, lecturers, and advisers in animal science, but is also a core text for advanced undergraduate courses in animal science and biotechnology. It will be an essential acquisition for librarians in agriculture and veterinary science.
