Download or read book Determining Growing-finishing Pig Lysine Requirements and the Effects of Potassium Bicarbonate and Crystalline Lysine Level on Finishing Pig Performance written by Rafe Quinnlan Royall and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Variations in feeding frequency may lead to difference in utilization of dietary nutrients. The effects of feeding frequency have been tested in growing pigs and finishing pigs using respiratory quotient and postprandial kinetics of plasma metabolites. A reduced feeding frequency resulted in an increased lipogenesis and proteolysis shortly after the meal both in growing and finishing pigs. Nevertheless, growing and finishing pigs exhibit different metabolic pathways when feeding frequency is reduced.

Download or read book Determining the Lean Growth Curve for Growing-finishing Pigs from the Lysine Requirements Estimated by Using Plasma Urea Nitrogen as a Rapid Response Criterion written by Ruilan Wei and published by . This book was released on 2001 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2011-05-02 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than 30 years, modelling has been an important method for integrating, in a flexible, comprehensive and widely applicable way, basic knowledge and biological concepts on digestion and metabolism in farm animals. The purpose of this book is to present the 'state of art' in this area. The chapters are written by leading teams and researchers in this field of study, mainly from Europe, North America and Australasia. Considerable progress has been made in topics dealing with: modelling methods, feeding behaviour, digestion and metabolic processes in ruminants and monogastric animals. This progress is clearly illustrated by the emergence of a new paradigm in animal nutrition, which has moved from the aim to cover the requirements of the animal to explaining and predicting the responses of the animals to diets (e.g., productivity and efficiency, impact on quality of products, environmental aspects, health and well-being). In this book several chapters illustrate that through empirical models, meta-analysis is an efficient tool to synthesize information gathered over recent decades. In addition, compared with other books on modelling farm animal nutrition, two new aspects received particular attention: expanding knowledge of the individual animal to understanding the functioning and management of herds, and the consideration of the environmental impact of animal production. This book is a valuable source of information for researchers, nutritionists, advisors, and graduate students who want to have up-to-date and concise information on mathematical modelling applied to farm animals.

Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, animal scientists have learned that administering recombinantly derived somatotropin (growth hormone) to cows improves milk production and that giving beta-adrenergic agonists to meat animals improves productivity and leanness. In order for these metabolic modifiers to yield benefits, however, sound management of the animals' nutrition is necessary. This volume reports on how these substances work in the animals' metabolism, what effects they might have on nutrient requirements of domestic livestock, and what information should be developed further by investigators. The book explores the current understanding of the biology, structure, mechanisms of action, and treatment effects of somatotropin, beta-adrenergic agonists, and anabolic steroids. A companion volume to the Nutrient Requirements of Domestic Animals series, this authoritative volume will be required reading for animal scientists, researchers, veterinarians, livestock farmers, and faculty and students in university animal veterinary science programs.
