This book was released on 1999 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of digestion and metabolism experiments with pigs and poultry were conducted to evaluate the variation in available energy values in 18 samples of commercial normal corn (NC) and to compare the energy utilization of NC hybrids and three samples of high-oil corn (HOC) hybrids. Our studies at the University of Missouri estimated the variation of available energy values of NC hybrids to be approximately 5% for swine DE and ME values, 8% for adult rooster TMEn values, and 9% for young broiler chicken AME values. In NC hybrids, there were no correlation relationships between crude protein (CP) and crude fat (ether extract), or CP and lysine, or CP and methionine contents. The available energy values for HOC hybrids were greater than NC hybrids in both swine and poultry. Since HOC hybrids contained more fat and protein than NC hybrids, it is reasonable that available energy values would be greater than NC hybrids. Also the average amino acids digestibility of HOC hybrids were greater (5%) than those of NC hybrids in young broiler chickens. Within NC hybrids, there were no correlation and regression relationships between swine and poultry energy values. Proximate analysis results can not be used to predict the in vivo energy values in NC hybrids. Poultry energy values (TMEn and AME) were not an adequate animal model for the prediction of the swine energy values between normal corn hybrids.

Book Synopsis Evaluation of Low Phytate Barleys and an in Vitro Procedure for Predicting Phosphorus Availability in Organic and Inorganic Sources of Phosphorus by : Vera Beatrice Badresingh
Download or read book Evaluation of Low Phytate Barleys and an in Vitro Procedure for Predicting Phosphorus Availability in Organic and Inorganic Sources of Phosphorus written by Vera Beatrice Badresingh and published by . This book was released on 2001 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three experiments were conducted to validate, in vivo, the increased phosphorus availability in low phytate barley suggested by laboratory phytate analyses and to determine if lowering the phytate content in low phytate barley would compromise its nutritional value. Six low phytate barleys (1 hull-less, 5 hulled) and two iso-geneic wild type barleys (1 hull-less 1 hulled) were used in each experiment. By analysis, hull-less wild type barley (NNB) contained 0.15% nonphytate P (nP) and 0.38% total P (tP); hull-less low phytate barley (NLPB) contained 0.22% nP and 0.34% tP; hulled wild type barley (NB) contained 0.12% nP and 0.36% tP; hulled low phytate barleys (LPB-1, LPB-2, and LPB-3) contained 0.20%, 0.27%, and 0.30% nP and 0.31%, 0.35% and 0.35% tP, respectively. Experiment 1 utilized the semi-purified method of feeding, while experiments 2 and 3 utilized commercial-type diets. Response variables were body weight gain, feed intake, tibia ash, toe ash and P retention. In experiment 3, analyzed ME and total amino acid values for the barleys were used in the formulation of the diets. The results of the three experiments demonstrated that P in low phytate barleys is more available than P in wild-type barleys, and decreasing the phytate content did not compromise its nutritional value. The increased availability of P in low phytate barleys has several benefits; the reduction of supplemental inorganic P addition to diets, reduction in P excretion thereby lessening the problem of P pollution, and improved utilization of nutrients bound by phytate. An in vitro method was developed to predict phosphorus (P) availability from inorganic phosphate sources. The in vitro procedure consisted of separate peptic and pancreatic digestion periods, designed to simulate the digestive conditions in poultry. Analysis of data was based on slope-ratio procedures. There were no statistical differences (P> 0.05) in P bioavailability or in vitro P release among the phosphate sources. Results of these studies indicated that the in vitro study may be useful in predicting relative bioavailability of inorganic phosphate sources. The in vitro method was also used to predict P availability from 15 plant-origin feed ingredients. Results of that assay indicated a significant positive correlation (R = 0.87) between in vitro P release and published in vivo P availability values for the 15 plant-origin feed ingredients and a significant positive correlation (R = 0.84) between in vitro P release and the analyzed non-phytate P values. The in vitro method presented here may be a valid alternative to conducting in vivo studies for ranking plant-origin feed ingredients with respect to P availability.
Book Synopsis Feed efficiency in swine by : John F. Patience
Download or read book Feed efficiency in swine written by John F. Patience and published by Springer Science & Business Media. This book was released on 2012-10-15 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Feed efficiency in swine' has been prepared as a comprehensive treatise on the current state of our understanding of this topic which is so important to the pork industry. Each chapter is written by international authorities who understand both the science and application of their topic area. The book provides detailed insight into the many factors affecting feed efficiency, ranging from diet processing to herd health, from nutrition to physiology and from day-to-day barn management to the adoption of advanced technologies. The authors explain such practical aspects as the challenge of interpreting feed efficiency information obtained on farm or the role of liquid feeding. The authors also delve into more scientific topics such as amino acid or energy metabolism or animal physiology. This book is written for people who have a technical interest in pork production, including nutritionists, geneticists, farm management specialists, veterinarians, other academics and, of course, pork producers.

Book Synopsis Masters Theses in the Pure and Applied Sciences by : W. H. Shafer

This book was released on 2012-12-06 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 22 (thesis year 1977) a total of 10,658 theses titles from 28 Canadian and 227 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 22 reports theses submitted in 1977, on occasion, certain universities do report theses submitted in previous years but not reported at the time.
