Mathematical Modelling in Animal Nutrition
Author: J. France
Publisher: CABI
ISBN: 1845933540
Category : Technology & Engineering
Languages : en
Pages : 588
Book Description
The primary purpose of each of the subsequent chapters of this book is to promulgate quantitative approaches concerned with elucidating mechanisms in a particular area of the nutrition of ruminants, pigs, poultry, fish or pets. Given the diverse scientific backgrounds of the contributors of each chapter (the chapters in the book are arranged according to subject area), the imposition of a rigid format for presenting mathematical material has been eschewed, though basic mathematical conventions are adhered to.

Determining Growing-finishing Pig Lysine Requirements and the Effects of Potassium Bicarbonate and Crystalline Lysine Level on Finishing Pig Performance

Book Description
This thesis involves two studies to determine the effects of standardized ileal digestible (SID) lysine (Lys) requirements of growing-finishing pigs from 18 to 128 kg of body weight (BW) as well as evaluating the effects of adding potassium bicarbonate (KHCO3) to diets with high or low crystalline lysine (L-Lys HCl) to influence dietary cation-anion difference (DCAD). Five experiments involving 2,903 pigs were conducted to determine the SID Lys requirement for maximum growth and economic return at five weight ranges throughout the growing and finishing phases. Using this data, we were able to create a pair of quadratic equations to estimate the SID Lys to Net Energy (NE) ratio required to achieve maximum growth potential and economic return throughout the growing-finishing phase. the quadratic equation of Lys:calorie ratio, g of SID Lys/Mcal of NE = 0.0002611 x BW2, in kg - 0.0711037 x BW, in kg, + 7.284 was developed to reflect requirement for maximal growth performance from 18 to 128 kg BW. Optimal IOFC is best described by the quadratic equation: Lys:calorie ratio, g of SID Lys/Mcal of NE = 0.0001558 x BW2, in kg, - 0.04030769 x BW + 5.410. Additionally, these results suggest that the most economical SID Lys level from 18 to 100 kg is below that for maximal growth rate. However, in 103 to 128 kg pigs, the SID Lys requirements for maximum growth performance and economic return are much more closely aligned. A second project utilized 1,944 pigs to determine if balancing DCAD levels, via added KHCO3, in diets containing low or high levels of L-Lys HCl influences finishing pig growth performance or carcass characteristics. Dietary cation-anion difference is a measure of the level of monovalent ions (Na+, K+, and Cl−) within the diet, which correlates to the acid-base balance within the animal. Extreme DCAD levels, both high and low, have been shown to negatively impact feed intake and growth in pigs, previous research shows that a wide range may optimize performance.

Feed efficiency in swine
Author: John F. Patience
Publisher: Springer Science & Business Media
ISBN: 9086867561
Category : Science
Languages : en
Pages : 264
Book Description
'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.

Determining the Lean Growth Curve for Growing-finishing Pigs from the Lysine Requirements Estimated by Using Plasma Urea Nitrogen as a Rapid Response Criterion

Languages : en
Pages : 204
Book Description
From the lysine requirements obtained in Exp. A and C, the lean growth rates of individually penned PIC barrows were calculated to be 334, 372, 404, 414, 340, 327, and 276 g/d at 33, 52, 69, 72, 87, 93, and 113 kg body weight, respectively. Fitting the data to a polynomial least square regression, a lean growth curve was derived: Y = ( - 0.11606 + 0.04895X - 0.0005855X2 + 0.000001963X3) x 347, where Y was the lean growth rate in grams/day, X was the BW in kilograms. Exp. B determined the lysine requirements of PIC barrows under group penned situation. The results showed that each barrow required 15.8 ± 1.7 and 18.9 ± 1.4 g true ileal digestible lysine/d at 32 and 50 kg body weight, respectively. PUN responses did not allow valid estimates of the lysine requirements for group penned finishing pigs.
