Book Description
Cattle feeders are considering alternative feedstuffs to replace expensive corn grain and decrease rations costs. Feeding corn silage allows cattle feeders to take advantage of the entire corn plant at a time of maximum quality and tonnage as well as secure substantial quantities of roughage and grain inventory. Distiller's grains have proven to be economical and are now a commonplace ingredient in feedlot finishing diets. Experiments were conducted to determine the effects of feeding increased concentrations of corn silage in replacement of corn grain in finishing diets containing distillers grains. Feedlot gains and gain:feed ratios were reduced as corn silage increased in the diet. Total tract dry matter digestibility of diets containing 45% corn silage was decreased compared to diets containing 15% corn silage. Although total tract neutral detergent fiber (NDF) concentration was not different across corn silage inclusions, in-situ NDF disappearance of corn bran was greater for diets with increased corn silage inclusion. Whole corn plants were sampled and analyzed for two consecutive years for determination of the effects on whole corn plant yield and quality measurements due to hybrid season length, planting density, and whole plant harvest timing. As whole plants were harvested later in the season, yield increased with minimal changes in whole plant quality measures. The economic factors involved in pricing corn silage were assessed, and different economic scenarios were developed for feeding corn silage in finishing diets containing distillers grains. Feeding increased concentrations of corn silage in finishing diets containing distillers grains was determined economical when corn grain price was above $163.38 per metric tonne. As well, as corn grain price and the inclusion of corn silage in the diet increased, reducing corn silage shrink and harvesting corn silage at higher DM contents became more economically beneficial. These data demonstrate that corn silage can economically replace corn grain in finishing diets containing distillers grains.

Book Description
Beef Cattle Feeding and Nutrition is the third in a series of books on animal feeding and nutrition. These books are designed to keep readers abreast of the rapid developments in feeding and nutrition. These developments have resulted in changes in diets, the use of new feed processing methods, improved use of by-product feeds, and more supplementation with minerals, vitamins, amino acids, and nonprotein nitrogen compounds. The book is organized into four parts. Part I focuses on the nutrient requirements of beef cattle. Beginning with a review of rumen physiology and energy requirements, the remaining chapters discuss the vitamin, mineral, and protein, requirements of beef cattle. Part II on feedingstuffs includes studies on pasture and other forages; hay and haylage making; silage and crops for silage; and concentrates for beef cattle. Part III includes studies on breeding herd nutrition and management; and milk production and calf performance. Part IV on cattle finishing covers cattle finishing systems; feedlot disease; and economics of cattle feeding.

Book Description
"This book is essential reading for all those involved in forage conservation and provides a fascinating insight into current practices and the science underpinning forage conservation. Key subject areas include opportunities to enhance the fermentation process through crop manipulation prior to ensiling and the use of bacterial additives applied during ensiling. Latest developments in techniques for chemical and biological characterisation of silages are reviewed, including grass silage, alternative forages (whole crop wheat and maize silage) and tropical forages. The book also focuses on current developments in feeding of beef and dairy cattle with conserved forage with particular emphasis on factors influencing intake, digestion and animal performance. Overall this is an important reference book, which provides an excellent overview of current developments in forage conservation and utilization of conserved forage in animal production systems."

Book Description
Six studies were conducted to evaluate effects of corn silage harvest, hybrid, and concentration in growing and finishing diets. Experiment 1, evaluated corn silage DM (37 or 43%) and replacing corn grain with silage (15 or 45% of diet DM) in finishing diets. Experiment 2, evaluated corn silage DM (37 or 43%) and response to rumen undegradable protein (RUP) supplementation in growing diets. Experiment 3, evaluated nutrient digestibility of 37 or 43% DM corn silage at two different intakes. Experiment 4, 5, and 6 evaluated three corn silage hybrids: a standard hybrid control (CON), a brown midrib (bm3) hybrid (BM3), and an experimental bm3 hybrid (BM3-EXP) with a soft endosperm trait. Experiment 4 evaluated the three hybrids and concentration (15 or 45% of diet DM) in finishing diets, while Exp. 5 and 6, evaluated the same three silage hybrids in growing diets. In Exp. 1 with finishing cattle, as DM of silage increased from 37 to 43%, there were no differences (P ≥ 0.30) in DMI, ADG, or G:F. In Exp. 2 with growing cattle, as DM of silage increased from 37 to 43%, ADG and G:F were reduced (P ≤ 0.04). Increasing supplemental RUP in the diet increased (P ? 0.05) ending BW, ADG, and G:F linearly. In Exp. 1 and 4, as concentration of silage in the finishing diet increased from 15 to 45%, ADG and G:F decreased (P ≤ 0.04). In Exp 4, BMR-EXP had the greatest ADG and G:F at 15% silage. At 45% silage, both bm3 hybrids had greater (P ≤ 0.05) ADG than CON, but G:F was greatest for cattle fed BM3 (P

Book Description
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.
