This book was released on 2017 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four dual-flow continuous fermenters were used in a Latin square design to determine the apparent ruminal digestibility and ruminal characteristics of diets containing dried distillers grains plus solubles (DDGS) at various levels of fat content. Fermenters were randomly assigned to one of the following treatments: 1) 40% DDGS containing 4.82% fat content (40 LOW); 2) 40% DDGS plus corn oil to obtain 7.5% fat (40 MED); 3) 40% DDGS plus corn oil to obtain 10.5% fat (40 HIGH); or 4) 70% DDGS plus corn oil to obtain 7.5% fat (70 MED). Rumen fluid was collected at the beginning of each period from two ruminally cannulated Angus cows previously adapted to the 40LOW treatment. Each period consisted of 10 days with a seven day adaptation period followed by three days of sample collection. Calories per gram of diet increased as percent fat increased and calories per gram was greater at the 70% inclusion of DDGS compared to 40% inclusion of DDGS at all levels of fat content. However, level of fat in the diet did not influence (P ≥ 0.35) apparent ruminal digestibility of DM, NDF, ADF, CP or total calories. Similarly, inclusion rate of DDGS had no influence (P ≥ 0.35) on nutrient digestibility. Ammonia concentrations were greatest (P = 0.0002) for 70 MED compared to the other treatments. However, treatment had no impact (P ≥ 0.16) on volatile fatty acid production with the exception of propionate which increased (P =0.05) as the level of DDGS increased from 40 to 70% inclusion rate. This data would suggest that level of fat content of DDGS has no negative influence on apparent ruminal digestibility and select ruminal characteristics. From an economic perspective, higher fat DDGS should have a higher price differential, but lower fat DDGS can still be an effective protein and energy substitute.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Three trials were conducted using dried distiller's grains with solubles (DDGS) to evaluate effects on feedlot performance, carcass characteristics, ruminal fermentation, and diet digestibility in cattle fed steam-flaked corn-based diets. In trial 1, crossbred yearling heifers were used in a finishing trial to evaluate interactions between corn-DDGS feeding levels and roughage source (alfalfa hay vs corn silage) in terms of impact on feedlot performance and carcass characteristics. Experimental diets were based on steam-flaked corn and contained 0% DDGS with 6% alfalfa hay (AH), 0% DDGS with 10% corn silage (CS), 25% DDGS with 6% AH, or 25% DDGS with 10% CS (DM basis). Results indicated no interaction between levels of DDGS and roughage source. Heifers fed DDGS as a partial replacement for steam-flaked corn had similar growth performance and carcass merit compared to heifers fed diets without DDGS. Corn silage and alfalfa hay were comparable roughages when a portion of steam-flaked corn was replaced with DDGS. The second trial was a companion metabolism study in which ruminal fermentation characteristics and diet digestibility were examined in 12 cannulated Holstein steers fed steam-flaked corn finishing diets with or without DDGS, using alfalfa hay or corn silage as roughage sources. Diets were similar to those fed in the performance study and consisted of steam-flaked corn with 0 or 25% DDGS (DM basis) and 6% AH or 10% CS (DM basis). Feeding DDGS decreased ruminal pH and ruminal ammonia concentrations, and digestion of DM and OM were less compared to diets without DDGS. The decrease in digestibility was largely attributable to poorer digestion of CP and, to a lesser extent, a reduction in starch digestion. The third study was designed to investigate effects of pH (5.0, 5.5, and 6.0) on in vitro fermentative activity by ruminal microorganisms from cattle adapted to a finishing diet containing 25% DDGS (DM basis). Higher pH led to greater dry matter disappearance in vitro (P

Available in PDF, EPUB and Kindle. Book excerpt: This is the second edition of Horse Feeding and Nutrition which was originally published in 1980. It provides the latest information available for those interested in the feeding and nutrition of horses. This new edition has been entirely revised to include the large amount of new research information that has become available since publication of the first edition. Three new chapters have been added, entitled Feeding and Health-Related Problems, The Complexity of Proper Bone Formation, and Exercise Physiology. New feed and food crops, improved methods of production and processing, increased productivity of animals and crops, changes in animal products including more lean and less fat in meat and less fat in milk, longer shelf-life requirements of animal food products, and a myriad of new technological developments have resulted in a need to continually re-evaluate nutrient requirements and supplementation. Sample diets are given, useful as guides in developing diets for horses. Suggested levels of protein, minerals, and vitamins for use in horse diets are presented. These can be used as guides which can be modified to suit the various feeding situations encountered in horse farms. The volume of scientific literature is increasing rapidly each year. Moreover, its interpretation is becoming more complex. This increases the need for summarizing and interpreting these new developments in up-to-date books such as in this one.

This book was released on 2005 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two experiments were conducted to evaluate corn distiller's solubles (CDS), a co-product from dry grind ethanol plants, in beef steers fed corn-based diets. In Exp. I, four pens of steers were fed for 109 d diets containing 0, 4, 8 or 12% CDS. Daily feed, gain and gain/feed were 9.4, 10.1, 10.0, and 10.1 (kg/d); 1.75, 1.78, 1.76, and 1.79 (kg/d); 0.185, 0.177, 0.176, and 0.179; for the four respective diets. Feed intake increased when CDS was fed (P = 0.012). Gain, gain/feed, and carcass traits were not statistically different (P> 0.1). In Exp. II, ten steers were used in a digestion study to evaluate diets containing 4 and 8% CDS, or 10 and 20% wet corn distillers grain with solubles (WDGS). The steers were placed in digestion crates for total collection of feces and urine. Intake (kg/d) of DM, starch, NDF, ADF, CP, and fat were: 7.99, 8.71, 8.62 & 8.41, 7.83; 4.92, 4.87, 4.93, & 4.81, 3.95; 1.19, 1.25, 1.19, & 1.42, 1.42; 0.43, 0.48, 0.45, & 0.56, 0.55; 0.96, 1.08, 1.03, & 1.03, 1.03; 0.27, 0.35, 0.43, & 0.43, 0.50; for 0, 4 or 8% CDS and 10 or 20% WDGS. Respective apparent digestibility of DM, starch, NDF, ADF, CP, and fat were 79, 78, 76 & 77, 76; 97, 94, 95, & 95, 94; 53, 52, 46 & 52, 56; 41, 45, 37, & 48, 50; 72, 72, 70, & 69, 69; 63, 66, 65, & 68, 75. Feeding distillers co-products did not affect DM intake or digestibility of NDF, ADF, or CP (P> 0.05), but did increase fat intake (P

This book was released on 2000-05-16 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: As members of the public becomes more concious of the food they consume and its content, higher standards are expected in the preparation of such food. The updated seventh edition of Nutrient Requirements of Beef Cattle explores the impact of cattle's biological, production, and environmental diversities, as well as variations on nutrient utilization and requirements. More enhanced than previous editions, this edition expands on the descriptions of cattle and their nutritional requirements taking management and environmental conditions into consideration. The book clearly communicates the current state of beef cattle nutrient requirements and animal variation by visually presenting related data via computer-generated models. Nutrient Requirements of Beef Cattle expounds on the effects of beef cattle body condition on the state of compensatory growth, takes an in-depth look at the variations in cattle type, and documents the important effects of the environment and stress on food intake. This volume also uses new data on the development of a fetus during pregnancy to prescribe nutrient requirements of gestating cattle more precisely. By focusing on factors such as product quality and environmental awareness, Nutrient Requirements of Beef Cattle presents standards and advisements for acceptable nutrients in a complete and conventional manner that promotes a more practical understanding and application.
