Book Synopsis Intermittent fasting in chickens by : Caroline Lindholm
Download or read book Intermittent fasting in chickens written by Caroline Lindholm and published by Linköping University Electronic Press. 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.

Book Synopsis Goose Production by : Roger B. Buckland
Download or read book Goose Production written by Roger B. Buckland and published by Food & Agriculture Org.. This book was released on 2002 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication aims to provide guidance on sustainable goose production systems that are based on the natural physiological and behavioural advantages of the goose. These advantages include the fact that: they can consume and digest large amounts of high fibre and low-quality feed; they are easy to manage; and their rapid growth renders them one of the most efficient sources for meat production. In addition, feathers/down and fatty liver are valuable by-products, while their strong territorial instinct makes them very effective guards. As selective feeders, geese have been used for weed control in a wide range of crops. All aspects of goose production are discussed in this book, including feeding and nutrition, housing, general husbandry, flock heath and breeding. Regional differences in production practices are also described.

Download or read book Cancer written by Victor R Preedy and published by Academic Press. This book was released on 2014-03-01 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cancer: Oxidative Stress and Dietary Antioxidants bridges the trans-disciplinary divide and covers in a single volume the science of oxidative stress in cancer and then the potentially therapeutic usage of natural antioxidants in the diet or food matrix. The processes within the science of oxidative stress are described in concert with other processes such as apoptosis, cell signaling, and receptor mediated responses. This approach recognizes that diseases are often multifactorial and that oxidative stress is a single component of this. Oncologists, cancer researchers, and nutritionists are separated by divergent skills and professional disciplines that need to be bridged in order to advance preventative as well as treatment strategies. While oncologists and cancer researchers may study the underlying pathogenesis of cancer, they are less likely to be conversant in the science of nutrition and dietetics. On the other hand, nutritionists and dietitians are less conversant with the detailed clinical background and science of oncology. This book addresses this gap and brings each of these disciplines to bear on the processes inherent in the oxidative stress of cancer. - Nutritionists can apply information related to mitochondrial oxidative stress in one disease to diet-related strategies in another unrelated disease - Dietitians can prescribe new foods or diets containing anti-oxidants for conditions resistant to conventional pharmacological treatments - Dietitians, after learning about the basic biology of oxidative stress, will be able to suggest new treatments to their multidisciplinary teams - Nutritionists and dietitians will gain an understanding of cell signaling, and be able to suggest new preventative or therapeutic strategies with anti-oxidant rich foods

Book Synopsis Choosing Sexes by : Kristen J. Navara
Download or read book Choosing Sexes written by Kristen J. Navara and published by Springer. This book was released on 2018-02-01 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is extensive evidence that vertebrates of all classes have the ability to control the sexes of the offspring they produce. Despite dramatic differences in the mechanisms by which different taxa determine the initial sex of offspring, each group has found its own way of adjusting offspring sex ratios in response to social and environmental cues. For example, stress is a well-known modulator of offspring sex in members of all groups studied to date. Food availability, and limitation in particular, is another common cue that stimulates biases in offspring sex ratios in a wide variety of species. Offspring sex can be adjusted at the primary level, which occurs prior to conception, or at the secondary level, during embryonic development. While the mechanistic pathways that ultimately result in sex ratio biases and the developmental time-points sensitive to those mechanisms likely differ among taxa, the key involvement of steroid hormones in the process of sex ratio adjustment appears to be pervasive throughout. This book reviews the systems of sex determination at play in different vertebrate groups, summarizes the evidence that members of all vertebrate taxa can facultatively adjust offspring sex, and discusses when and how these adjustments can take place.
