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.

Book Synopsis Animal nutrition strategies and options to reduce the use of antimicrobials in animal production by : Food and Agriculture Organization of the United Nations
Download or read book Animal nutrition strategies and options to reduce the use of antimicrobials in animal production written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2021-07-15 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antimicrobial resistance is a global and increasing threat. Stewardship campaigns have been established, and policies implemented, to safeguard the appropriate use of antimicrobials in humans, animals, and plants. Restrictions on their use in animal production are on the agenda worldwide. Producers are investing in measures, involving biosecurity, genetics, health care, farm management, animal welfare, and nutrition, to prevent diseases and minimize the use of antimicrobials. Functional animal nutrition to promote animal health is one of the tools available to decrease the need for antimicrobials in animal production. Nutrition affects the critical functions required for host defence and disease resistance. Animal nutrition strategies should therefore aim to support these host defence systems and reduce the risk of the presence in feed and water of potentially harmful substances, such as mycotoxins, anti-nutritional factors and pathogenic bacteria and other microbes. General dietary measures to promote gastrointestinal tract health include the selective use of a combination of feed additives and feed ingredients to stabilize the intestinal microbiota and support mucosal barrier function. This knowledge, used to establish best practices in animal nutrition, could allow the adoption of strategies to reduce the need for antimicrobials and contain antimicrobial resistance.

The first section of this book contains six chapters that discuss the utilization of unconventional feeds, nanominerals to reduce mineral proportions in diets, and water intake affected by environmental temperature. The second section contains six chapters that describe proper nutritional management to improve gut health and immunity, the prevention of common diseases, and the amelioration of heat stress in poultry.
Book Synopsis Effect of Male Broiler Breeder Feeding Programs on Growth, Reproductive Performance, and Broiler Progeny by :
Download or read book Effect of Male Broiler Breeder Feeding Programs on Growth, Reproductive Performance, and Broiler Progeny written by and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Four studies were conducted to evaluate the effects of different feeding programs during rearing and production on broiler breeder male growth, fertility, and progeny performance. In Experiment I, the effects of two levels (High and Low) of cumulative nutrient intake during the rearing period to photostimulation at 21 wk of age through different dietary formulations or feeding programs were evaluated. The High cumulative nutrition program supplied 33.5 Mcal ME and 1,730 g CP, while the Low cumulative nutrition program supplied 29.6 Mcal ME and 1,470 g CP. At 21 wk of age in Experiment I-2, males were classified into Heavy or Light BW groups. A cumulative nutrient intake during the rearing period of 29.6 Mcal ME and 1,470 g CP, regardless of diet or feeding program resulted in a male of adequate BW that was able to maintain good fertility throughout the production period and produce broilers with increased 42-d BW. In Experiment III, two levels of dietary CP (12% and 17%) and two feeding programs (Concave and Sigmoid) were evaluated during the rearing period to 26 wk of age. The Concave or 17% CP treatments were unable to sustain fertility after 40 wk of age without an increased allocation of feed. In Experiments II, two antioxidant levels and different source of selenium were evaluated during the production period. In Experiment IV different feeding programs from 16 to 26 wk of age and during the production period were evaluated. The data showed that feed allocation relative to BW affected fertility more than did antioxidant inclusion. Furthermore, slow and consistently increasing feed increments from 16 to 26 wk of age and during the production period improved fertility and favorably impacted progeny performance. In conclusion, when males failed in accumulate adequate nutrients during the rearing period or gain adequate BW, as an indication of ME allocation, after photostimulation fertility declined and significant negative effects were observed in progeny performa.

This book was released on 2009-01-01 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is compelling evidence that many of the risks leading to the most frequent chronic diseases in adulthood originate in the earliest stages of life. Adverse environmental conditions in utero and during infancy can lead to negative health effects during the subsequent lifetime of the exposed individual.This book offers precious insights into the latest concepts and results from epidemiologic, clinical and basic studies in this burgeoning area of health care. The developmental origins of various diseases such as diabetes, obesity and cancer are examined, as well as the early programming of reproductive health and different organs. Attention is given to the impact of environmental factors such as nutrition and pollution, and the mediating genetic and epigenetic pathways are reviewed. A crucial point under discussion is the concept of environmental insults adversely affecting not only the exposed persons, but also their descendants. In addition, the economic consequences of a suboptimal start to life and the importance of preventive measures are stressed.This publication is of great value to anyone interested in health care, notably to specialists in obstetrics, pediatrics, internal medicine, obesity, diabetes and heart disease.

This book was released on 2019-10-16 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Broiler breeder chickens are the parent stock used to produce broiler chickens raised for human consumption and have long been caught in a welfare dilemma. The immensely successful selection of fast-growing meat-type chickens over the last 80 years has created a remarkably efficient meat-producer and given us access to cheap chicken meat but has also created health problems for the animals. These problems especially affect the breeder generation, which must be raised with strict feed restriction to limit weight gain and thus maintain physical health and normal fertility. At the same time, however, feed restriction causes chronic hunger and feeding frustration with reduced animal welfare as a result. In the EU alone 60 million breeders are affected annually and although the problem is well-known within the industry, there is financial incentive to keep selecting for even higher growth potential in broilers, further increasing the problems for broiler breeders. Many strategies for reducing the impact of growth restriction on breeder welfare have been suggested and are usually aimed at somehow increasing the amount of feed given at feeding times. This can be done either through adding bulky fibers to the diet or by reducing feeding frequency. In this thesis, focus is on the latter as we explore the effects of intermittent fasting (IF) on the welfare of young broiler breeders as well as wild-type Red Junglefowl. Intermittent fasting, or “skip-a-day” feeding, is supposedly the most common feeding strategy for broiler breeders worldwide but is perceived as welfare-reducing and thus illegal in Sweden and several other European countries. In spite of this, the scientific knowledge of how this type of feeding affects chicken welfare is scarce. Assessing the overall effect of IF on breeder welfare is complicated by large variations in both physiological and behavioral parameters between feeding and fasting days, but it does appear that chicken welfare is improved at least on the feeding days of IF regimens. It also seems that some of the health benefits reported from mammalian studies of IF may apply to chickens as well, although behavioral indicators still point to welfare issues unless the level of feed restriction can be relaxed. In comparison with daily feed restriction, IF appears to increase the motivation for feed consumption but to reduce the motivation for appetitive behaviors such as foraging, which may explain why birds fed on this type of schedule are often reported as calmer.
