Three experiments were conducted to determine the effects of cattle age and dietary forage level on the utilization of corn fed whole or ground to feedlot cattle. In Exp. 1, 16 steers were used to investigate the effects of cattle age and corn processing on diet digestibility. Two cattle age categories were evaluated (weanling [254 +/- 20 kg BW] and yearling [477 +/- 29 kg BW]; eight steers per...

The goats raised in the barn are usually fed on fresh grass. As dry forage can be stored for long periods in large amounts, dry forage feeding makes it possible to feed large numbers of goats in barns. This review explains the physiological factors involved in suppressing dry forage intake and the cause of drinking following dry forage feeding. Ruminants consume an enormous amount of dry forage...

The scope of this paper is to describe the work of manual sugarcane harvesters, assessing the nutritional behavior and body composition between the beginning and the end of the harvest. A descriptive longitudinal study was made of harvesters in Piracicaba, São Paulo, Brazil, who answered a socio-demographic questionnaire and authorized measurement of Body Mass Index, Body Fat Percentage and Arm...

The objective of this study was to evaluate the effects of forage level and oil supplement on selected strains of rumen bacteria believed to be involved in biohydrogenation (BH). A continuous culture system consisting of four fermenters was used in a 4×4 Latin square design with a factorial arrangement of treatments, with four 10 d consecutive periods. Treatment diets were: i) high forage diet ...

An interpretation technical and economic indicators characterizing transport proposed, features determining productivity tractor unit, cost one transported ton are considered. Probability theory was to determine “Load waiting time”, “Vehicle loading time”. condit...

Civil and Environmental Engineering) Control of Vibratory Energy Harvesters in the Presence of Nonlinearities and Power-Flow Constraints by Ian L. Cassidy Department of Civil and Environmental Engineering Duke University

R7 stage (one seed pod at mature color; 50% of leaves yellow) produced forage that was similar in quality to Tall forage soybean [Glycine max (L.) Merr.] cultivars in maturity alfalfa harvested at early bloom. When soybean was groups V, VI, and VII have been developed to supply forage. Our objective was to determine the effect of harvest date and row spacing grown as an intercrop with corn, the...
