This book was released on 2005 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Triticale is a small grain resulting from an intergeneric cross between durum wheat and rye. The study consisted of four trials: two in winter (November 2003 through March 2004) and two in summer (May 2004 through September 2004) at the ISU Western Research and Demonstration Farm, Castana, Iowa. Each trial consisted of six pens of ten pigs (five barrows, five gilts) in three small-scale hoop barns (6.0 x 10.8 m). Pens were randomly assigned one dietary treatment: 1) corn-soybean meal control (0% triticale), 2) 40% Trical 815 triticale diet (by weight) or 3) 80% Trical 815 triticale diet. Feed and water were presented ad libitum. Pigs started on experiment at 72 kg and were fed 49 d. At the end of each trial all pigs were scanned for backfat (BF) thickness and loin muscle area (LMA). Barrows from one winter and one summer trial were evaluated for meat and fat quality and sensory evaluation of pork. End weights and average daily gain (ADG) were greater during winter than summer (treatment x season interaction, P

This book was released on 2005 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Producers are becoming more aware of product quality as a profit driver in the pork industry. One alternative method is the use of hoop buildings, which are deep-bedded, open-ended, tent-like structures covered with a polyethylene fabric tarp. Several items differ between hoop structures and standard confinement systems, including the use of straw for bedding, increased space allocation, and subjection of animals to seasonal environmental changes. The open-ended design of hoop structures allows greater exposure to temperature changes, with less capacity to maintain a constant temperature as outdoor temperatures fluctuate. The following experiments were designed to ascertain affects between hoop systems to confinement systems. The general hypothesis driving this study was that enrichment of the finishing environment provided by semi-outdoor, deep-bedded finishing systems would allow for lower stress susceptibility, thereby influencing growth response, carcass composition, the rate and extent of pH and temperature decline postmortem, ultimately affecting pork quality attributes perceived by the consumer. Space allocation rates from this study will grant producers using these systems with a standard stocking requirement to efficiently optimize swine growth and pork quality. Hoop-finished pigs were slower growing, with relation to average daily gain and feed conversion capacity than confinement-finished pigs. Hoop pigs also had lower levels of backfat at the 10th rib, less marbling in the loin, and less total lipid in the adipose tissue. The ultimate driver hypothesized for these variations was exposure to ambient temperature fluctuations. Providing more space within hoop systems had small affects on growth, performance, or pork quality attributes. Variations in pork quality were limited to lipid deposition, indicating finishing systems observed in these experiments did not alter product quality. Future research initiatives are necessary to determine specific effects of temperature fluctuation and lipid deposition characteristics in these systems.

Book Synopsis Gaining the edge in pork and poultry production by : J. Taylor-Pickard
Download or read book Gaining the edge in pork and poultry production written by J. Taylor-Pickard and published by BRILL. This book was released on 2023-08-28 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Globally, pork and poultry production has become an extremely competitive industry. There is now more pork consumed in the world than any other meat, yet there is still intense competition for the industry to attract and retain consumers. Consumers continue to demand safe, high quality pork and poultry products at competitive prices compared to other high protein food alternatives. To ensure sustainability of both the pig and poultry industries, producers must endeavour to seek new technologies to improve production efficiency whilst lowering the cost of production and producing a quality product. This edited collection of articles 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 and production. The fundamental theme is to re-examine the current trends in productivity within the pig and poultry industries, and to identify nutritional and managerial means to improve competitiveness as well as the quality of the end product. The importance of animal health together with novel strategies for disease control and ways to minimise the environmental impact of pig and poultry production are covered. ‘Gaining the edge in pork and poultry production’ is aimed at nutritionists and animal producers as well as students and researchers studying animal and applied biological sciences.

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.

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 Effect of Reducing Dietary Protein Level and Adding Amino Acids on Performance, Carcass Characteristics, and Nitrogen Excretion of Finishing Pigs by : Haijun Liu
Download or read book Effect of Reducing Dietary Protein Level and Adding Amino Acids on Performance, Carcass Characteristics, and Nitrogen Excretion of Finishing Pigs written by Haijun Liu and published by . 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.
Book Synopsis Effects of Pelleting and Dietary Fat and Fiber Levels on Pig Growth and Fat Quality by : Jeremiah Eugene Nemechek
Download or read book Effects of Pelleting and Dietary Fat and Fiber Levels on Pig Growth and Fat Quality written by Jeremiah Eugene Nemechek and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In 11 experiments, 7,325 pigs were used to determine the effects of: 1) diet type and form on finishing pig growth performance and carcass fat iodine value (IV); 2) pellet quality and feeder adjustment on pig growth performance; 3) corn particle size and diet form on finishing pig growth performance and carcass characteristics; and 4) dietary acidification, diet complexity, and feed-grade antibiotics on nursery pig growth performance. Feeding diets with wheat middlings and dried distillers grains with solubles all the way until marketing decreased G:F and carcass yield, and worsened carcass fat IV. Withdrawing these ingredients 17 d prior to market restored carcass yield, but resulted in small improvements in IV. Pelleting diets improved growth performance; however, a novel finding is that pelleting diets fed to finishing pigs increased belly fat IV. Feeding nursery pigs from a wide feeder gap may improve ADG and ADFI, with no negative effects on G:F. For finishing pigs, reducing feeder gap reduced feed disappearance and improved G:F. In all experiments, feeding pelleted diets improved G:F, but the greatest improvements occurred when the percentage of fines was minimized. Grinding corn finer than 650 microns decreased ADFI and improved G:F for finishing pigs fed meal diets, but not for pigs fed pelleted diets. Pelleting diets improved ADG and G:F, but the greatest magnitude of G:F improvement to pellets occurred when pigs were fed diets containing the largest particle size corn. Thus, grinding corn finer than 650 microns improved feed efficiency for finishing pigs fed meal diets, but provided no additional benefit for pigs fed pelleted diets. When dietary supplementation of benzoic acid was evaluated, added benzoic acid in nursery pig diets did not influence growth performance in university conditions, whereas feeding complex diets or antimicrobials improved growth. In the commercial setting, acidifiers improved growth in one experiment but not the other. The varying response to acidifiers is likely influenced by health status, age, or starting weight of pigs.
Book Synopsis The Effects of Dietary Fat Source and Feeding Duration on Pig Growth Performance and Fat Quality by : Ethan Wade Stephenson
Download or read book The Effects of Dietary Fat Source and Feeding Duration on Pig Growth Performance and Fat Quality written by Ethan Wade Stephenson and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In 3 experiments, 4,720 pigs were used to determine the effects of: 1) dietary fat and feeding duration on growth performance and fat quality in finishing pigs; or 2) a novel protease or 3) increasing levels of Zn amino acid complex (ZnAA) or ZnO on finishing pig performance. Experiment 1 tested the effects of feeding tallow, soybean oil, or a blend of the two for various feeding durations (d 0 to 42, 42 to 84, or 0 to 84). Overall, pigs fed added fat for the entire 84 d had improved G:F compared to those fed a control diet. Additionally, pigs fed additional fat for the entire study had improved ADG and G:F as well as increased d 84 BW compared to pigs fed additional fat for 42 d. Increasing the feeding duration of soybean oil lowered monounsaturated fatty acids and increased polyunsaturated fatty acid concentrations while these values remained relatively unchanged by the addition of tallow. There were feeding period by fat source interactions for fatty acid composition and iodine value for belly and backfat, but not jowl fat, indicating a longer turnover rate for jowl fat compared to belly or backfat. In Exp. 2, adding a protease to a nutrient deficient diet increased ADFI and tended to increase ADG compared to pigs fed a negative control diet. There were no differences observed in ADG, ADFI, or G:F between pigs fed a positive control diet, formulated to 90% of the pigs SID lysine requirement, and those fed a negative control diet plus the protease, which would suggest the release values attributed to the enzyme were accurate. In Exp. 3, supplementing additional Zn from either ZnAA or ZnO at 25, 50, or 75 ppm in finishing diets for commercial finishing pigs was evaluated. Overall, no differences were observed in ADFI, but a Zn source by level interaction was observed for ADG and G:F, as pigs fed increasing ZnO were observed to have similar performance, while pigs fed added levels of 25 and 50 ppm Zn from ZnAA had decreased performance compared to those fed the highest level of ZnAA.
