This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous research indicates that dietary fat utilization by the newly-weaned pig is low, while fat digestive capabilities prior to weaning are very high. Sow milk contains approximately 40% fat, whereas nursery diets are rarely formulated to contain more than 5%. The aim of this experiment was to determine if emulsification (plus or minus Tween-80), physical form of the diet (liquid vs dry) or fatty acid chain length (medium (MCT) vs long chain triglyceride (LCT)) effect fat utilization by the newly weaned pig. Two replicates were performed in the summer of 2006 at the NCSU Swine Educational Unit. Pigs (N= 96) were weaned at 20 " 0.30 d of age (6.8 " 0.04 kg) and fed one of eight dietary treatments for 14 d according to a 2x2x2 factorial design. The MCT fat contained primarily C8 and C10 fatty acids while the LCT fat was supplied by choice white grease. Each fat was spray dried with or without the inclusion of Tween-80 emulsifier (at 2% wD) and comprised 12% of the final diets. Diets were otherwise formulated to exceed NRC nutrient requirements. Liquid diets were reconstituted with water to 13% dry matter and were offered ad libitum via milk-replacer feeders (Kane Manufacturing). Diet physical form greatly accelerated piglet growth (P 0.05), with liquid-fed pigs (0.49 kgD) out gaining dry-fed pigs (0.340 kgD) by 44%. Triglyceride chain length also impacted growth (P

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.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the use of agro-industrial co-products has significantly increased in pig diets resulting in increased dietary fiber. It is, however, intriguing that nutrient utilization and performance are depressed if pigs consume nutritionally balanced high-fiber diets that are composed of co-products plus supplementary fat. The first study indicated that addition of soluble fiber from Flaxseed meal (FM) and insoluble fiber from Oat hulls (OH) in pig diets increased intestinal VFA and BA contents but reduced fecal fat digestibility and induced variable effects on the histological characteristics, and composition and function of digesta- and mucosa-associated microbiota in gastrointestinal segments. Moreover, soluble fiber from FM depressed growth performance. The second study showed that soluble fiber from FM and insoluble fiber from OH reduced, ileal digested energy, FA digestibility, and absorption, gastrointestinal flows of FA and excretion of BA and both dietary fiber sources induced variable effects on digestibility of DF fractions, hindgut VFA production and fecal flows of unsaturated FA. The third study investigated the interactive effects of DF solubility and lipid type on digestibility of DF and FA, and flows of FA and BA in the ileum, cecum and colon, and VFA production and absorption in the cecum and colon of growing pigs. The production and absorption of VFA and DF fermentability in the cecum and colon was greater in pigs fed soluble fiber from Pectin compared to those fed insoluble fiber from Cellulose, and beef tallow supplementation depressed fermentation compared to corn oil. The interaction between DF solubility and lipid type modulates digestibility of lipids, flows of FA and BA and fermentability of DF fractions but differs for soluble and insoluble fiber, and saturated and unsaturated fatty acids. Lastly, the fourth study revealed that soluble from FM and insoluble fiber from OH increased the VFA uptake, and transportation and induced comparable effects on expressions of mRNA of colonic and hepatic genes involved in lipid metabolism. Taken together, soluble and insoluble fiber reduce fatty acids digestibility and induce variable effects on growth performance, intestinal fermentation, histomorphology, expression of genes involved in lipid metabolism and gastrointestinal microbiota composition.
Download or read book Facts about fats written by J. Doppenberg and published by BRILL. This book was released on 2023-09-04 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fats and oils are more than 'just' energy sources for animal feeds. The fatty acids as part of triglycerides or in Fatty Acid products differ in chemical composition and physical characteristics. The omega-3 and specifically the LC-PUFA omega-3 fatty acids can be considered as functional nutrients. Via the feeding of different fats and differing fat additions body composition and animal products can be modified. The main use of fats and oils in the feed industry is however increasing the energy content of the feed economically. Therefore knowledge about the digestibility of the fat for each animal category, the metabolisible energy content and the efficiency with which this energy can be used for different production goals are of paramount importance for evaluating the fat source of choice. This book has summarized the presently available knowledge from the scientific literature and concluded with a model to estimate the energy content in practice.

Available in PDF, EPUB and Kindle. Book excerpt: Four experiments were conducted to determine the effects of supplemental rumen-protected fat in feedlot rations. The first experiment tested the effects of supplemental calcium and magnesium salts of fatty acids on ruminal fermentation and duodenal fatty acid flow in beef steers fed forage-free diets. These saponified fatty acids did not disrupt ruminal fermentation but provided little protection from ruminal biohydrogenation under these conditions. The second experiment evaluated the effects of increasing levels of calcium salts on feedlot performance and carcass characteristics. A moderate (6.2%) level of calcium salts had no effect on average daily gain (ADG) or feed efficiency (FE). However, ADG and FE were decreased when calcium salts were fed at 8.7% of the diet. The third experiment evaluated the effects of calcium salt supplementation in traditional and forage-free feedlot diets on feedlot performance and carcass characteristics. Supplemental rumen-protected fat had no effect on ADG or FE but decreased ribeye area (REA) when fed at 6.5% of the diet. The fourth experiment evaluated the effects of feeding calcium salts on feedlot performance, carcass characteristics, and blood metabolites that affect the growth of feedlot animals. Supplemental rumen-protected fat decreased ADG and intake with no effect on FE when fed at 6.5% of the diet. In addition, calcium salts had little effect on carcass measurements and blood metabolites.

Available in PDF, EPUB and Kindle. Book excerpt: Recently, there has been tremendous scientific interest in the role of phospholipids and particularly phosphatidylcholine (lecithin) in a variety of biological processes. These include the involvement of phosphatidylcholine in biological membranes, as a component of plasma lipoprotein, as a transporter of choline in the body, and also as a "reserve", and possibly only source of unesterified choline. Moreover, numerous clinical studies have recently been conducted, to evaluate the possible uses of externally supplied lecithin in the treatment of some intractible neuropsychiatric disorders (e.g. tardive dyski.nesia, Alzheimer's disease, etc.) and other conditions (e.g. hypercholesteremia). Results to date are encouraging, yet equivocal. This is due, in part, to the fact that the field of phospholipid methodology is highly complex. There is much confusion in the literature, and many ambiguities still remain in the interpretation of experimental findings. This is particularly so for phenomena involving phospholipid function in the central nervous system. This book incorporates the proceedings of the Fourth International Colloquium on Lecithin, which took place in Chicago, Illinois, USA, on September 15-17, 1986. The purpese of this colloquium was to review, in a comprehensive manner, basic principles as weli as current information about the technology, biochemistry, physiology and therapeutic potential of lecithin. Over 108 individuals from all over the world participated in the sessions. The meeting was subdivided into oral presentations and panel discussions (see Table of Contents). It was sponsored and financed by the Lucas Meyer GmbH (Hamburg), for which the editors are most grateful.
