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
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
A finishing experiment evaluated the effect of incremental supplemental rumen-protected lysine on beef cattle performance. All cattle were fed the same diet of high moisture corn, dried rolled corn, modified distillers grains plus solubles, corn silage, and supplement with inclusion levels of lysine ranging from 0 to 7 grams/day, in 1 g increments. Dry matter intake (P ≤ 0.04) and ADG (P ≤ 0.04) decreased linearly as supplemental lysine increased in the diet with no effect on final carcass adjusted feed efficiency (P ≥ 0.34). In the initial 64 days of the experiment, increasing lysine in the diet linearly decreased ADG (P ≤ 0.05) with a trend (P = 0.08) to linearly decrease feed efficiency. During the Optaflexx feeding period, DMI decreased linearly (P ≤ 0.01) with no effect on carcass adjusted ADG (P ≥ 0.51) or feed efficiency (P ≥ 0.34). Hot carcass weight tended to decrease linearly (P = 0.07) with no significant differences in carcass quality characteristics (P ≥ 0.20). In diets containing 15% modified distillers grains plus solubles, increasing supplemental lysine in the diet did not improve performance of finishing cattle. A finishing experiment evaluated the effect of a pistachio shell-sourced biochar on emissions and finishing performance of beef cattle. All cattle were fed the same diet of dried rolled corn, Sweet Bran (Cargill Wet Milling, Blair, NE), wheat straw, and supplement with biochar replacing 0.5% of dried rolled corn in the biochar treatment group. Eight pens of cattle were rotated as pairs through a 2-chambered emissions barn for 5 days for 8 consecutive weeks to analyze CH4 and CO2 produced by the cattle (2 measurement periods per pair). Biochar tended to increase CH4 emissions on a g/day basis (P = 0.09) with no effect on CH4 emissions as g/kg of DMI. There were no statistical differences in CO2 emissions as g/day or g/kg of DMI. Final performance, HCW, LM area, and marbling, did not differ between treatments (P ≥ 0.23). However, the control group tended to have improved 12th rib fat (P = 0.07) and yield grade (P = 0.06) compared to the biochar group. Including biochar at 0.5% of diet DM did not reduce eructed CH4 or respired CO2 and did not improve performance.
