Download or read book Modelling Nutrient Digestion and Utilisation in Farm Animals written by D. Sauvant and published by Springer Science & Business Media. 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.

This book was released on 2016 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Barrows and gilts (215/gender) were used to test the effects of synthetic AA supplementation of reduced CP diets on the growth performance and quality characteristics of the LM and the fatty acid composition of the LM and s.c. jowl fat from growing-finishing swine. Pigs were blocked by BW within gender, and allocated randomly to pens (6 pigs/pen) which were then assigned randomly within each block and gender to either corn-SBM diets 1) that were devoid of synthetic lysine (Ctrl); 2) with reduced CP diets where lysine was added to all diets (RCP1); 3) with reduced CP where lysine, threonine, and tryptophan were added to all diets (RCP2); 4) with where lysine, threonine, and tryptophan were added to all diets (RCP3); or 5) with reduced CP diets where lysine, threonine, tryptophan, and isoleucine was added to all diets (RCP4). During finisher phase 3, 10 mg/kg of ractopamine was included in all diets. A subsample of whole pork loins was processed into chops for data collection. Another subsample from the whole pork loin and the s.c. fat from each jowl was freeze dried for fatty acid determination. Gilts had a greater (P = 0.02) (lightness) L* value and drip loss than barrows, but the ultimate pH, marbling, and intramuscular fat (IMF) of the LM were greater (P 0.04) for barrows than gilts. Color measurements were not affected (P 0.06) by the RCP diets, with the exception of redness (a*) which increased (P = 0.01) with decreasing CP levels. There were greater (P

Book Synopsis Effects of Dietary Lysine on Muscle Gene Expression and Fatty Acid Profiles and on Selected Carcass Characteristics and Plasma Hormone Concentrations in Late-stage Finishing Pigs by : Taiji Wang
Download or read book Effects of Dietary Lysine on Muscle Gene Expression and Fatty Acid Profiles and on Selected Carcass Characteristics and Plasma Hormone Concentrations in Late-stage Finishing Pigs written by Taiji Wang and published by . This book was released on 2016 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dietary inclusion of sufficient lysine is very critical for optimizing pig’s growth performance. The objectives of this project were to study the effects of dietary lysine at different concentrations on (1) the growth performance and carcass characteristics, (2) the muscle gene expression profile and the possible alterations to the metabolic and signaling pathways, (3) the muscle fatty acid profile, and (4) the plasma concentrations of growth-related hormones of late-stage finishing pigs. Nine crossbred barrows were assigned to 3 dietary treatments (lysine-deficient, -adequate, and -excess diets) according to a completely randomized experimental design. During the 5-week feeding trial, pigs were allowed ad libitum access to experimental diets and water. All pigs and experimental diets were weighed individually each week during feeding trial to determine growth performance. After harvest, the carcass characteristics were determined and muscle samples were collected from longissimus dorsi for mRNA and fatty acid profiling, while the jugular vein blood was collected at the end of four weeks for analyses of three growth-related hormones. While the average daily gain showed a quadratic relationship, the dressing percentage and total lean cut weight both increased linearly with dietary lysine concentrations. Results of muscle gene expression data showed that dietary lysine deficiency may lead to decreased protein synthesis, increased protein degradation and lipid accumulation, while dietary lysine excess may lead to decreased protein degradation and increased lipid biosynthesis. Fatty acid (FA) composition data showed that different dietary lysine concentrations altered the intramuscular fat (IMF) content and FA composition, especially the unsaturated FAs. In particular, dietary lysine deficiency increased the IMF content and the proportion of mono-unsaturated FAs. Hormone analyses showed that the plasma concentrations of insulin and growth hormone were not affected by dietary lysine, whereas the concentration of insulin-like growth factor 1 was decreased by either dietary lysine deficiency or excess. Collectively, lysine may function as a signaling molecule to regulate the expression of genes related to protein turnover and lipid metabolism in the muscle of finishing pigs, causing differences in growth performance, carcass characteristics, and FA composition. IGF-1 may be a controlling growth factor that is sensitive to dietary lysine.

Book Synopsis Determining Growing-finishing Pig Lysine Requirements and the Effects of Potassium Bicarbonate and Crystalline Lysine Level on Finishing Pig Performance by : Rafe Quinnlan Royall
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.
