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.

Book Description
Six ruminally and duodenally cannulated Angus cross bred cows (680 ± 47.1 kg of initial BW) were utilized in a crossover design to evaluate the effects of method of processing supplemental corn on forage intake, digestive function, metabolizable protein, and ruminal fermentation. Cows were maintained in individual pens (5 x 4 m) and offered hay and corn at 0700. Hay was offered to ensure ad libitum intake and 10% feed refusal daily. Corn grain was supplemented at 0.2% of BW (as fed basis) and placed directly into the rumen through the ruminal cannula. Bluestem hay (Bothriochloa ischaemum; 5.7% CP, 69.4% NDF, and 11.49% ash, DM basis) was offered after corn supplementation. Treatments consisted of 1) ground corn (GC) and steam-flaked corn (SF). Experiment consisted of 2 experimental periods in which 9 d were for adaptation and 4 for rumen fluid, duodenal, and fecal samples collection. Hay DM intake and total DM intake were greater (P = 0.04) for GC than for SF. Also, intake of CP (P = 0.02), NDF (P = 0.04) were greater and starch intake (P = 0.01) was lower for GC than SF. The flow of nutrients to the duodenum (P ≥ 0.11) was not affected by corn processing method with the exception of starch which was greater (P = 0.01) for GC than SF, and therefore starch ruminal digestion was greater (P = 0.01) for SF. Microbial efficiency was not affected (P = 0.11) by corn processing method. Total tract digestion of DM (P = 0.007), OM (P = 0.09) and NDF (P = 0.11) tended to be lower, while total tract digestion of starch (P = 0.02) was greater for SF than GC. Ruminal pH, total VFA production, and ammonia concentration were not affected (P ≥ 0.18) by corn processing method. However, the proportion of acetate (P = 0.01; 74.4, and 71.7 ± 0.77 mol/100 moles) was greater, propionate (P = 0.06; 14.8, and 17.2 ± 0.81 mol/100 moles), and butyrate (P = 0.05; 7.2, and 8.3 ± 0.32 mol/100 moles) were lower for GC than for SF. Supplemental SF decreased low-quality forage intake without negatively impacting microbial protein and feed protein supply to the duodenum. Keywords: grain processing, low-quality forage, metabolizable protein, steam flaked corn

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
