Book excerpt: Amino acids (AA) are essential components of diets but accurate determination of AA requirements in farm animals is a challenge. Requirements for AA in pigs can be influenced by several factors, including genetics, health, age, and, as recently shown, also individual variability. In conventional group-phase feeding (GPF) systems, large groups of pigs receive the same feed during extended periods and most pigs receive more nutrients than required to express their growth potential with potential detrimental effects on the environment through increased nitrogen excretion, and on production costs. In individual precision feeding (IPF) systems, pigs are fed diets tailored daily to their individual nutrient requirements. In light of this, it is necessary to distinguish the AA requirements of a population from those of individuals. Optimal essential AA ratios have been established for pigs in conventional GPF systems, but these optimal AA ratios might differ for pigs in IPF systems. The main research objective was to compare the ideal protein profile in pigs using the optimal threonine-to-lysine (Thr:Lys) ratio between conventional GPF and IPF systems. Based on a dose-response approach with five levels Thr:Lys ratios offered to growing pigs in a GPF or IPF system, it was possible to confirm the initial hypothesis that optimal AA ratios differ between feeding systems. Carcass chemical composition and AA concentration was likewise affected by the Thr:Lys ratio, and the magnitude and type of response depended on the feeding system. In a second dose-response study with similar Thr:Lys ratios offered to late finishing pigs, requirements were larger than to those previously observed for growing pigs, suggesting that AA requirements for protein deposition is age dependent. These two studies suggest that individual pigs can modulate their growth and body composition according to the level of AA intake and can respond differently to same amount of ingested AA. These studies further highlighted the weakness of using an ideal protein profile by considering fixed requirements for AA due the assumed constant AA carcass composition. Accurate estimation of AA requirements for pigs in an IPF system seems to be mainly limited by the use of fixed AA ratios as pigs have different AA requirements. Finally, a novel approach to the dose-response approach based on a central composite design with a factorial design aiming at independently estimating real-time requirements for Lys and Thr in individual pigs was proposed. A non-unique response of protein deposition to various Thr and Lys combinations was observed due to the differences in AA requirements among individual pigs. This insight on variability among individual pigs is useful to fine-tune the precision feeding system by estimating AA requirements more accurately, feeding pigs according to their individual requirements, and, ultimately, reduce waste of nutrients in pigs with lower protein deposition. The results presented in this thesis support the idea that changes in body composition in pigs are induced by changes in dietary AA levels. Therefore, growth may be modulated to the optimal body composition desired by the consumer. This thesis proposes a change of perspective in animal nutrition, where AA may be seen as a trigger for animal metabolic response with dynamic and distinctive AA requirements in individual animals.

Book Synopsis Amino Acid and Energy Requirements of Growing-finishing Pigs Kept Under Low and High Sanitary Conditions by : C.M.C. van der Peet-Schwering
Download or read book Amino Acid and Energy Requirements of Growing-finishing Pigs Kept Under Low and High Sanitary Conditions written by C.M.C. van der Peet-Schwering and published by . This book was released on 2020 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study was performed to evaluate the effects of dietary energy source (starch vs fat) and of increased levels of dietary energy and essential amino acids (EAA), related to the assumed increased EAA and energy requirements in immune stimulated pigs, on the growth performance of growing-finishing (GF) pigs under low sanitary conditions (LSC), in which the immune system of the pigs was activated, or under high sanitary conditions (HSC) resulting in a lower state of activation of the immune system. The trial was conducted with 408 male pigs (Tempo boar x (York x Dutch Landrace) sow) during the weaner, grower and finisher phase. Piglets were weaned at an age of four weeks and followed till delivery to the slaughterhouse. In a 2 × 2 × 2 factorial design, pigs were allocated to either high sanitary conditions (HSC) or low sanitary conditions (LSC). A contrast in sanitary conditions was generated by imposing to the pigs differences in strategy for vaccination against pathogens, cleaning and hygiene protocol, antibiotic treatment and deworming. During the growing and finishing period, pigs had ad libitum access to one of four experimental diets, a diet with starch as main energy source or a diet with fat and starch as main energy source, each diet having either basal energy and EAA concentrations (B diet) or increased concentrations in energy and EAA (I diet). The levels of supplementation of EAA and energy in the I diets compared to the B diets were based on a model that calculated the effects of low sanitary conditions on the EAA and energy requirements of pigs. At an age of nine weeks, pigs were moved to the rooms for GF pigs. The HSC GF pigs were fed a starter diet during the first five weeks, followed by a grower diet for four weeks and then a finisher diet till delivery to the slaughterhouse. The LSC GF pigs were fed a starter diet during six weeks, followed by a grower diet for four weeks and then a finisher diet till delivery to the slaughterhouse. In all pens, 8 or 9 GF pigs were housed.

Book Synopsis Effects of Low Crude Protein, Amino Acid Fortified Diets and Neutral Detergent Fiber on Finishing Pig Performance by : Jose Alfredo Soto Gonzalez
Download or read book Effects of Low Crude Protein, Amino Acid Fortified Diets and Neutral Detergent Fiber on Finishing Pig Performance written by Jose Alfredo Soto Gonzalez and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Eleven experiments using 5,434 growing-finishing pigs were performed in addition to the development of a model to predict dietary NE that yields the greatest economic benefit. Two experiments were conducted to determine the effect of dietary phytogenics on growth and carcass performance of growing-finishing pigs. The addition of the combination of two phytogenics products (EOM 1+2) to diets improved ADFI, HCW, and carcass ADG. However, there was no evidence for treatment differences for growth or carcass performance in a second study. Two experiments were conducted to determine the effects of feeding high SID Trp:Lys ratios with and without Ractopamine HCl (RAC) on growth and carcass characteristics of finishing pigs. In Exp. 1, whereas increasing SID Trp:Lys ratio above 20% improved growth and carcass performance when diets contained RAC, pigs fed SID Trp:Lys ratios above 20% in diets without RAC had reduced growth and carcass performance. Contrary in Exp. 2, pigs fed increasing SID Trp:Lys in diet containing RAC did not provide further performance benefits. Three experiments were conducted to determine the optimum dietary SID Lys and CP concentrations in finishing pigs over 100 kg. The SID Lys requirement to obtain 100% of maximum response was 0.55 to 0.63% depending on the response variable. Growth and carcass performance was maximized in diets containing at least 12% dietary CP. Four experiments were conducted to determine the effects of SBM concentration and whether dEB, choline, or K are the reasons that performance is reduced when pigs over 100 kg BW are fed low CP diets. Performance was reduced as SBM concentration was reduced in the diet. Choline, K, and dEB do not appear to be the reason that performance is reduced when SBM concentration is decreased in low CP diets fed to pigs over 100 kg BW. A Microsoft Excel®-based model to predict the value of dietary NE that yields the greatest economic return to the production system was developed. Furthermore, a meta-analysis was conducted to incorporate the impact of NDF on carcass yield in the model.

Book Synopsis Metabolic Modifiers by : National Research Council
Download or read book Metabolic Modifiers written by National Research Council and published by National Academies. This book was released on 1994-02-01 with total page 94 pages. 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.
