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.

This book was released on 2000 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: A total of eight experiments utilizing 572 finishing pigs were conducted to evaluate the effect of reducing dietary protein level and adding amino acids on pig performance, carcass characteristics, and N excretion. The valine requirement of early-finishing (50 to 80 kg) barrows and the effect of adding isoleucine (Ile) and valine (Val) in amino acids fortified low-protein diets on finishing pig performance were also evaluated. In the first experiment (Exp. 1 of Chapter II), it was determined that the CP level in the diet for early-finishing (50 to 80 kg) gilts can be reduced up to four percentage units by adding Lys, Thr, Trp, and Met, with no detrimental effect on pig performance or carcass characteristics. The second study (Exp. 2 of Chapter II) indicates that Ile and/or Val may be limiting in a four-percentage-unit-protein-reduced diet for late-finishing (80 to 120 kg) gilts. The third experiment (Exp. 1 of Chapter III) indicates that the true digestible Lys requirement of early-finishing PIC barrows is not higher than 0.70%. In the fourth experiment (Exp. 2 of Chapter III), it was demonstrated that dietary protein level for early-finishing PIC barrows can be reduced up to five percentage units by adding Lys, Thr, Trp, Met, and Ile, with no detrimental effect on pig performance or carcass characteristics. Valine was not limiting in a 10.49% CP diet for early-finishing PIC barrows with ADFI of 3.1 kg/d, and the true digestible Val requirement of early-finishing PIC barrows gaining 1.0 kg/d, was not greater than 11.4 g/d. In the fifth experiment (Exp. 3 of Chapter III), we found that decreasing dietary protein level by 4.81 percentage units and adding amino acids to the diet reduced N excretion of early-finishing barrows by 40.6%. In the sixth experiment (Exp. 4 of Chapter III), it was determined that the dietary protein level for early-finishing barrows can be reduced up to four percentage units by adding Lys, Thr, Trp, and Met, with no detrimental effects on pig performance or carcass characteristics, and reducing dietary protein level by four percentage units can reduce N excretion by 38.4%. In the seventh experiment (Exp. 1 of Chapter IV), it was determined that late-finishing barrows fed an amino acid (Lys, Thr, Trp, Met, Ile, and Val) fortified corn diet (7.92% CP) have similar performance and carcass characteristics as pigs fed a corn-soybean meal control 12.50% CP diet. Deleting Ile or Val in an amino acids fortified corn diet may decrease pig performance. In the eighth experiment (Exp. 2 of Chapter IV), it was determined that late-finishing gilts fed an amino acid (Lys, Thr, Trp, Met, Ile, and Val) fortified corn diet (9.55% CP) have similar performance and carcass characteristics as pigs fed a corn-soybean meal control 15.17% CP diet. Decreasing dietary CP level from 15.17 to 9.55% decreases N excretion of late-finishing pigs by 48.28%. Deleting Ile or Val in an amino acid fortified corn diet may decrease pig performance. In summary, finishing pigs fed a low protein diet properly fortified with crystalline amino acids can have similar performance and carcass characteristics as pig fed typical protein level corn-soybean meal control diets, and N excretion will be greatly reduced.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In 6 experiments, a total of 1,802 pigs were used to determine: 1) effects of increasing crystalline amino acids in sorghum- or corn-based diets on nursery or finishing pig growth performance; 2) effects of different Zn sources on nursery pig performance; and 3) effects of different corn oil sources on nursery pig performance. In the first set of experiments, corn or sorghum-based diets were supplemented with increasing levels of synthetic amino acids up to the 5[superscript]th limiting amino acid. For nursery pigs, there were no main or interactive effects (P>0.05) of grain source or added amino acids which suggests that balancing up to the fifth limiting amino acid is possible in both sorghum- and corn-based diets with the use of crystalline amino acids without detrimental effects on nursery pig growth performance. For finishing pigs, balancing to the 5[superscript]th limiting AA using NRC (2012) suggested amino acid ratios in corn- or sorghum-based diets resulted in decreased ADG and G:F and pigs fed corn-based diets had greater G:F and IV than those fed sorghum. The second set of studies compared two new zinc sources to a diet containing pharmacological levels of ZnO on nursery pig growth performance. These studies demonstrated that increasing Zn up to 3,000 ppm Zn increased ADG and ADFI. Lower levels of the new zinc sources did not elicit similar growth performance as the high level of ZnO. The third set of studies compared increasing levels of different sources of corn oil to diets containing soy oil. In the first study, an oil source × level interaction was observed (P

This book was released on 2013 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two 35-d experiments were conducted to investigate the effect of reducing crude protein by 2.5% and diet complexity with amino acid supplementation on performance and feed cost during the nursery phase. In Exp. 1 and 2, 32 PIC barrows (initial wt. = 7.28 ± 0.44 and 6.89 ± 0.77 kg, respectively) were weaned at 21 d and allotted to one of four dietary treatments in a completely randomized design (RCD) with four replicate pens per treatment with two pigs/pen. The four diets were: 1) corn-soybean meal based diet; 2) diet 1 with inclusion of fishmeal (FM) and spray-dried plasma (SDP) in Exp. 1 or soy protein concentrate (SPC) and spray-dried blood cells (SDBC) in Exp. 2; 3) low crude-protein diet (LCP) with 2.5% reduction; 4) LCP containing FM and SDP in Exp. 1 or SPC and SDBC in Exp. 2. In order to reduce CP by 2.5%, diets were supplemented with synthetic lysine, methionine, threonine and tryptophan (Trp) in Exp. 1 and in Exp. 2, LCP diets were additionally fortified with synthetic valine (Val) and isoleucine (Ile). Blood samples were collected on d 14, 21, 28 and 35 for determining plasma urea N (PUN). Growth performance was determined weekly. Overall in Exp. 1, pigs fed corn-soybean meal based diet containing higher CP had greater ADG (P = 0.001) than pigs fed LCP diet (0.60 vs. 0.52 kg/d, respectively) and final BW (25.28 vs. 22.95 kg, respectively) (P = 0.002). Pigs fed diets containing FM and SDP had higher final BW when compared to pigs fed less complex diets (24.87 vs. 23.35 kg, respectively) (P = 0.034). These data suggest that Val and Ile become the next limiting amino acids in LCP nursery diets. In Exp. 2, there was no effect on overall ADG and final BW. However, pigs fed HCP diets had decreased ADFI (P = 0.009) when compared to pigs fed LCP diets (0.92 vs. 1.01 kg/d, respectively). Meanwhile, pigs fed diets containing SDBC and SPC had decreased ADFI (P = 0.019) compared to pigs fed noncomplex diets (0.93 vs. 1.00 kg/d, respectively). Overall in Exp. 1 and 2, pigs fed LCP diets had lower PUN concentration (P

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies were conducted to evaluate the effects of corn byproducts high-protein died distillers grain (HP-DDG), and dried distillers grain with solubles (DDGS), and branched chain amino acids (BCAA) on the growth performance and meat quality of pigs. The first study evaluated the combined effect of dietary level of DDGS and HP-DDG on the growth performance of wean-finish pigs and carcass and pork quality characteristics. This study demonstrated that DDGS can be included at up to 30% in diets (without HP-DDG) without compromising growth performance of wean-to-finish pigs. However, growth performance was increasingly compromised at higher inclusion levels of both co-products and belly firmness was negatively affected by increasing levels of both DDGS and HP-DDG. A second experiment was designed to define the minimum CP level and whether non-essential amino acids become limiting in low crude protein diets for late finishing pigs. The results of this study demonstrated that late finishing pigs can be fed diets with 9.76% crude protein level supplemented with 0.32 % L-Lys HCL and other essential amino acids without affecting growth rate and that non-essential amino acids were not limiting in the low crude protein diets evaluated. A third study was designed to recreate the negative effects on growth performance of feeding diets with 30% HP-DDG inclusion level and to test if the negative effect of feeding high HP-DDG levels on growth performance can be reproduced by adding excess branched chain amino acids (leucine, isoleucine, and valine) to standard corn-soybean meal based diet. The results show that the reduction in the growth rates of growing pigs fed diets with 30% HP-DDG inclusion levels may be due to the dietary excesses of leucine present in diets with HP-DDG at 30% inclusion levels. The same effect was not present in finishing pigs. In general, growth performance and belly quality are compromised at higher inclusion levels of both HP-DDG and DDGS. The results of the last studies indicate that leucine level may play an important role on the reduction of the growth performance of pigs fed 30% HP-DDG inclusion levels.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-crude protein (CP) diets supplemented with crystalline amino acids (CAA) in swine production reduces nitrogen (N) excretion into the environment, and reduces the concentration of non-essential amino acids (NEAA) and N, potentially limiting growth and important metabolic processes. Therefore, this thesis investigates whether supplementing NEAA glycine (Gly) and serine (Ser) to a low-CP diet will improve growth performance, and skin collagen abundance, and to determine if additional threonine (Thr) supplementation will spare Gly and Ser. Glycine and Ser supplemented diets had similar skin collagen abundance to CON while glutamate (Glu) diets resulted in lower collagen abundance and growth performance. Pigs fed low-CP diets supplemented with Thr had lower performance, but supplementation with 2.8 x Thr rescued collagen abundance in experiment two. Skin collagen abundance and processes beyond protein retention, have unknown implications for long-term productivity of pigs, therefore when feeding low CP diets supplementation with specific NEAA may be warranted.

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

This book was released on 2017-05-11 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, the concept of standardized ileal digestibility (SID) of crude protein (CP) and amino acids (AA) has been used in diet formulation for pigs. However, there is limited data on the nutritional composition and SID of CP and AA in home-grown European soybean and rapeseed products. For full-fat soybeans (FFSB), the presence of heat-labile trypsin inhibitors may cause problems in protein digestion of pigs. Therefore, the optimization of heat treatment for FFSB is a need to reduce trypsin inhibitor activity for improving SID of CP and AA. However, excessive heat treatment may have a negative effect on protein digestion. Furthermore, reducing dietary protein levels in combination with the supplementation of Bacillus spp. may reduce feed costs and improve pigs’ gut health. As a result of the present study, home-grown European soybean and rapeseed products can be considered as a suitable alternative to imported soybean products for pigs raised in organic and conventional farming systems. Wet heating at 100°C for 16 min, together with autoclaving at 110°C from 15 to 45 min reflects optimal heat treatment for FFSB resulting in greater SID of CP and AA with lower destruction of AA. Reducing the dietary CP level is an alternative strategy to improve SID of some AA, thereby decreasing feed cost and nitrogen excretion. The supplementation of Bacillus spp. promoted gene copy numbers of Roseburia spp., which may be beneficial due to ascribed health promoting properties of this butyrate producer.

This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Liquid diets provide a useful tool for producers with low birth weight pigs, as these pigs are at a disadvantage compared to larger littermates. There is limited use of milk replacers on commercial farms due to the high cost of protein sources. A way to potentially reduce the cost of liquid diets is to replace protein sources with synthetic amino acids (AA). Experiment 1 was designed to determine the amount of synthetic lysine (SL) that could replace lysine from protein and maintain performance similar to pigs fed a diet containing no SL. Pigs (1.62"0.20 kg) were randomly allotted to diets which replaced 0 to 40% of lysine from protein with SL, while maintaining similar GE and total lysine. Diets were fed on a restricted basis (n=4D iet) in order to reduce intake differences. An additional group was fed the 0% SL replacement diet ad libitum (AL, n=5) to determine intake level. Intake for restricted pigs was restricted to 80% of AL and adjusted on a daily basis. Pigs fed AL had greater (P 0.01) ADG, ADFI, G:F, water, CP, fat, and ash accretion than restricted fed pigs. Gain, G:F, water, CP, and ash accretion decreased (P

Book excerpt: Providing laying hens diets with a reduced crude protein (CP) content that are supplemented with free amino acids (AA) to cover the AA requirement might be helpful in reducing the soybean meal content of Latin American origin, and thus in reducing the amount of non-EU protein in the diet. This report describes the results of an experiment in which the effects of low CP diets, with a partial replacement of soybean meal by free AA, on laying performance, egg quality, and N-excretion were evaluated in laying hens from 39-51 weeks of age.

Available in PDF, EPUB and Kindle. Book excerpt: Animal production is constantly changing. Over recent years, feed costs have increased significantly. Furthermore, today more emphasis is being placed on the health and welfare of production animals and birds, and in particular to the risk of zoonoses and potential food scares. The pig and poultry industries must now address not only the costs and efficiency of production, but also the impact of health and disease to both animals and the consumer. This edited collection of papers is taken from a series of seminars that brought together some of the world's leading authorities in the field of pig and poultry nutrition, health and production. The fundamental theme is to address the issues of nutrition and health, and in particular to cover the interactions and potential conflicts between the two. The importance of digestive function and the influence of nutrition on health and disease are covered in-depth. Strategies to combat salmonella and mycotoxins are also discussed. 'Formula for the future: nutrition or pathology' is aimed at nutritionists, veterinarians and animal producers as well as students and researchers studying animal and applied biological sciences.
