Available in PDF, EPUB and Kindle. Book excerpt: Means of improving the quality of CM for poultry, including breeding for low-fiber canola and the use of exogenous enzymes, have been proposed. The objectives of the current study were: (1) To evaluate the chemical and nutritive composition of new yellow-seeded B. napus and B. juncea canola, (2) To investigate the effect of canola type and enzyme supplementation on AMEn and SID of amino acids, and growth performance of broiler chickens, (3) To explore the new carbohydrase enzymes for their ability to depolymerize NSP of CM in vitro, and (4) To evaluate the effect of new enzyme combinations in vivo with broiler chickens. In comparison with the conventional meal, yellow-seeded B. napus and B. juncea contained more crude protein, more sucrose, and less dietary fiber. The AMEn and SID amino acid values for yellow-seeded B. napus, B. juncea canola, and the conventional black-seeded B. napus were 1865, 2092 and 1902 kcal/kg DM, and 82.5, 83.2, and 81.8%, respectively. Enzyme addition resulted in a more pronounced effect on the AMEn content of B. juncea meal. When birds were fed diets containing 15% CM, BWG averaged 2.32, 2.30, 2.19, and 2.31 kg for the SBM-based Control, black and yellow B. napus, and B. juncea meals, respectively. A lower (P

This book was released on 1996 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research was to explore the potential for improved utilization of canola meal by monogastric animals. In study one, 26 yellow-seeded and 7 brown-seeded Brassica genotypes were evaluated for differences in chemical composition and dietary fibre profiles. On average, in comparison to brown-seeded, yellow-seeded genotypes contained more sucrose (8.7% vs 7.5%) and protein (44.5% vs 42.7%) and less dietary fibre (28% vs 33%). Dietary fibre was negatively correlated (r=-0.71) with protein content and its reduction in yellow-seeded samples was attributed to lower contents of lignin and polyphenols, cell wall protein and minerals associated with the fibre fraction. In a second study, selected Brassica genotypes were analyzed for digestible protein, soluble fibre, content of soluble phenolics and extract viscosity. Despite only minor differences in soluble fibre, soluble phenolics and extract viscosity, B. rapa and B. napus species had relatively high digestible protein content in comparison to B. juncea and B. carinata species. The measurements of digestible protein and dietary fibre as well as soluble phenolics and extract viscosity were poorly correlated. Based on chemical composition and digestible protein content, four Brassica cultivars were selected for use in a third study and the seeds were processed under optimal moist heat treatment conditions (108 + 1oC for 20 min). The samples included yellow-seeded B. rapa (cv. Parkland), B. rupus (cv. Y1016) and B. juncea (J4316) and brown-seeded B. rapus (cv. Excel). With the exception of B. rapa, all samples had higher than commercial meals protein content with the yellow-seeded B. napus canola showing the highest true metabolizable energy value. The overall performance of broiler chickens fed the Brassica seed meals was similar to that of the commercial meal from yellow-seeded canola (control) except for B. juncea which had a relatively high content of undesirable aliphatic glucosinolates. Of the diets with comparable growth performance, birds fed the yellow-seeded B. napus canola showed the highest feed efficiency value. In a forth study an attempt was made to improve the utilization of canola meal by supplementation of broiler chicken diets with exogenous enzymes. A positive and synergistic effect was noted when a combination of protease, carbohydrase and phytase enzymes were supplemented to canola meal-based diets deficient in available phosphorus.

Download or read book Canola Meal as a Protein Source in Chicken Diets written by Abdul-Rahman H. Nassar and published by . This book was released on 1985 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several experiments involving broilers and laying hens were conducted with the primary goal of evaluating the feeding value of Canola meal (CM) in both broiler and laying hen rations. A secondary goal was to study the growth response of broilers receiving higher concentrations of CM in their starter diets to supplements of protamone, arginine, methionine and/or zinc bacitracin. In the broiler experiments, satisfactory performance was obtained by feeding diets in which CM replaced up to 50% of soybean meal (SBM). However, growth and/or feed consumption and efficiency of feed utilization were adversely influenced by feeding CM at replacement levels higher than 50%. Protamone at 0.0025% of the diets containing CM at 50% and 100% reduced the enlarged thyroids of birds fed such diets to a size approaching that of controls, but a 0.005% level of protamone greatly reduced the size of the thyroids below that of birds fed the corn-SBM diet. No growth response was associated with the lower protamone dietary treatment, when a significant reduction in growth was observed to feeding the diets containing the higher protamone rate. Dietary supplements of arginine, methionine and zinc bacitracin did not appear to have a positive effect on performance of broiler chicks fed the starter diets at which CM substituted for higher levels of SBM. In all the broiler trials, there were no significant differences between the dietary treatments for the incidence of a leg abnormality condition, however, in experiment 4, when the chicks were fed the starter rations in which CM replaced 50% and 100% of SBM, a numerical increase in the occurrance of this condition was observed. In the laying hen experiment, CM which replaced up to 100% of SBM of the experimental rations, did not have any adverse effect on hen egg production, efficiency of feed utilization-, external and internal egg quality or final body weight. Fertility and hatchability of fertile eggs as well as dropping scores were also not significantly influenced by such dietary treatments. In both the broiler and laying hen trials, thyroid glands tended to be slightly enlarged with increasing levels of CM in the diets.

Available in PDF, EPUB and Kindle. Book excerpt: Canola meal (CM) is a less expensive protein ingredient than soybean meal (SBM) for livestock feed formulation. Canola processing has a major impact on the nutritional quality of the meal, limitations in the dietary inclusions are associated with reduced meal quality because of overheating during processing. Crude protein (CP) and amino acid (AA) digestibility are affected by differences in processing methods and conditions causing a variation in the chemical and nutritive value of the meal. As a result, protein quality of CM can be verified using standardized ileal digestibility (SID) of AA in young broiler chickens to ascertain values that are reliable for efficient feed formulation when considering high inclusion levels of CM in poultry diet. Two separate experiments were conducted to measure SID of AA of CM sourced from 14 crushing plants across Canada, as well as to determine the effect of varying inclusion levels of CM on growth performance and nutrient digestibility of young broiler chickens. There were significant variations in SID of Lys (86.3 vs. 74.2%), Trp (94.5 vs. 76.7%) and Thr (87.3 vs.71.6%) of CM for broiler chickens. Whereas, Met (91.8 vs. 87.4%) and Cys (81.8 vs. 73.7%) were not significantly affected but Arg, which is known as a conditionally essential AA, varied significantly (92.0 vs. 83.8%). Lysine (1.97 vs. 1.53%), Thr (1.64 vs. 1.24%) and Met (0.68 vs. 0.46%) as well as other AA varied significantly in their standardized ileal digestible contents, while a regression analysis showed a significant relationship among AA suspected to be heat sensitive. In the growth performance experiment, overall result revealed that neutral detergent fiber (NDF) content of diet differed substantially with increased levels of CM but bird performance was not significantly affected. Energy utilization varied with age of birds while NDF digestibility was not affected by incremental levels of CM inclusion.

Available in PDF, EPUB and Kindle. Book excerpt: From the PrefaceThe objective of this book is to review the basic knowledge and methodology of feeding grazing ruminants in tropical and semitropical countries. It is hoped this information will be of use to farmers, research specialists, teachers, students, extension specialists, feed manufacturers, and others throughout the world concerned with the nutrition of grazing ruminants. A unique feature is the identification of nutritional limitations of grazing ruminants in the tropics, which will be beneficial for increasing animal production efficiency through the application of improved nutrition. A large number of photographs illustrate nutritional deficiencies and conditions in tropical countries.This book contains 18 chapters concerned with the nutrition of grazing ruminants. The first chapter deals with the contributions, locations, and various types of ruminants and their importance to human welfare in the tropics and subtropics. Chapters 2 - 4 progress through nutrient requirements of grazing ruminants in warm climates, the effects of tropical heat on these requirements, and water requirements for ruminant species. Chapters 5 - 7 discuss grass and legume forage species suitable for tropical regions, pasture management procedures, and energy-protein supplementation programs needed during the extensive dry periods. The importance of tropical forages and soils toward meeting mineral requirements is discussed in Chapter 8. Chapters 9 -14 contain concise, up-to-date summaries of minerals emphasizing mineral status, incidence of mineral deficiencies and excesses in tropical regions, and benefits and methods of mineral supplementation for grazing ruminants are discussed in Chapters 15 - 17. Chapter 18 reviews vitamin nutrition considerations for ruminants consuming tropical forages.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the research was to explore the potential for improving the nutritive value of canola meal (CM) by pretreatment with a combination of enzymes during the canola seed crushing process. A number (12) of carbohydrase-like (i.e., _-galactosidase, pectinase, cellulase) and (2) phytase enzymes were evaluated 'in vitro' (80% moisture content) for their ability to hydrolyze oligosaccharides and phytate and to depolymerize the non-starch polysaccharides (NSP) of canola meal. Enzymes were selected based on their ability to reduce carbohydrate and phytate, their specific enzyme activity and source (manufacturer). The selected enzymes were combined into four enzyme blends. The study indicated that there is potential for improvement of the quality of canola meal by enzyme (blend) pretreatment. However, the relatively low moisture content in desolventized canola meal would appear to limit the effectiveness of pretreatment of canola meal during the crushing process and further research is needed to realize optimum effects of added enzymes. Studies were also conducted to investigate how and why enzyme supplementation influenced feed intake. To explain the mode of action of protease enzymes, casein or hydrolyzed casein and monosaccharides based diets with or without protease supplementation were used. (Abstract shortened by UMI.).
Download or read book Effects of Using Canola Meal as a Protein Source in Broiler Diets written by Charles Danny Bradley and published by . This book was released on 2013 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Six experiments were conducted to evaluate the response of broilers fed canola meal. Experiment 1 assessed performance and carcass yields when broilers were fed various combinations of canola and soybean meal in nutritionally balanced diets based on digestible amino acid values. The results suggested that canola meal can be used in isocaloric diets as a partial replacement for Soybean meal. Experiment 2 assessed broiler performance and carcass yields when using various levels of canola meal in broiler diets with a constant level of supplemental poultry oil. The resulting data suggested when diets are formulated with a constant level of supplemental fat; the level of CM should not exceed 10%. Experiment 3 and 4 were conducted simultaneously which examined two diet types Corn-Soy (CS), Corn-Soy-Canola (CSC) and four amino acid (AA) levels (80, 85, 90, and 95% of suggested level). ProAct and Cibenza protease enzymes were added at 3 different levels (0, 1, and 2 times suggested amount). The resulting data suggested performance for birds fed incrementally higher percentages of AA and the CSC improved. The addition of enzymes did not significantly improve BW. However, the addition of ProAct at 2 times suggested level improved FCR within the three-way interaction. Experiment 5 was conducted to evaluate pellet quality, broiler performance, and carcass characteristics of birds fed diet combinations of DDGS, SBM, and CM. These results concluded that 15 % DDGS and 20% CM can be used in combination without significantly affecting pellet quality. However, performance and parts yield displayed undesirable characteristics. Experiment 6 was conducted using two diet types; isocaloric and optimum nutrient density, two amounts of DDGS (0 and 15%) and six levels of canola meal (CM) (0, 5, 10, 15, 20, and 25%). The resulting data suggest if diets are maintained isocalorically any combinations of ≤ 15% DDGS and ≤ 25% CM without significantly decreasing performance. If diets are maintained at optimum nutrient density and 15% DDGS, CM can be added at 10, 15 and 20% levels without depressing BW or FCR. However, if diets are maintained at optimum nutrient density and 0% DDGS are added, CM cannot be added without depressing BW.
Download or read book The Effect of Pre press Solvent Extraction Conditions on the Chemical Composition and Nutritive Value of Canola Meal for Broiler Chickens and Pigs written by Deborah Adewole and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Canola meal (CM) which is commonly used in poultry and swine diets as an economically viable alternative to soybean meal is mainly produced by the process called the pre-press solvent extraction. The pre-press solvent extraction does not only involve many steps, each step also involves a wide range of vital conditions including temperature, moisture and time. Variations in these processing conditions among and within processing plants may contribute to inconsistency in the chemical and nutritive compositions of the resulting meals. In addition, the desolventization/toasting step of the pre-press solvent extraction process has been implicated for reducing both the content and availability of amino acids (AA), especially lysine, for both broiler chickens and pigs. Canola meal end-users desire increased meal consistency for a more accurate and cost-effective feed formulation and more information on the nutritive value and heat damage of AA. The first objective of this thesis was to determine the effect of processing plant and year on the chemical composition and indicators of protein damage in CM. To achieve this, a chemical composition survey of CM from 11 processing plants that use the pre-press solvent extraction process was conducted over a 4-year period. Differences among processing plants and years were observed for protein, lysine, dietary fiber and its components, fat, and carbohydrates components. Over the 4 years, the highest variation was observed in the contents of simple sugars having a coefficient of variation (CV) of 41.7%), neutral detergent insoluble crude protein (NDICP; CV = 16.8%) and glucosinolates (CV = 35.3%), the components known to be sensitive to heat treatment. Among all AA, only lysine showed differences (P
