I. The live-weight gain, carcass weight, edible carcass composition, efficiency of food conversion, and roughage intake were measured in three groups of calves fed for 87 d. After a 3-week feeding period on a common regimen, one gronp of calves was weaned on to a diet of dry whole-milk powder and chopped lucerne, the second group received a similar diet except that the wholc-milk powder was rec...

The aim of this experiment was to determine CH4 production and energy partition for a range of diets fed to Bos indicus cattle. Six Brahman cattle were fed on three different diets in a replicated Latin square experiment over three periods. The diets were (1) long-chopped Angleton grass (Dicanthium aristatum) hay ad libitum (DM digestibility (DMD) 41 (SE 2)%; 4 g N/kg), (2) long-chopped Rhodes ...

excellent mechanical properties of carbon nanotubes (cnts) make them outstanding candidate reinforcements to enhance mechanical properties of conventional composites. the glass/polyester composites are widely used in many industries and applications. improving the mechanical properties of such composites with addition of cnts can increase their applications. in this research, multi-walled carbo...

Potato vines are a potential feed for cattle if the vines can be preserved. The objectives of this study were primarily to study alternative methods to preserve potato vines by ensiling and determine the effects of soil contamination on ensiling. In experiment 1, vines from four potato varieties were harvested individually with a flail chopper set at three heights to vary soil contamination. Th...

A complete diet (Total Mixed ration) with sorghum stover (40%) as sole roughage source was prepared and offered to animals under two forms: as mash or as expanded-extruded pellets (EEP). These two complete diets were compared with a conventional diet (ad libitum chopped sorghum stover fed separately with concentrate mixture to meet 80% of protein requirements). These three diets were randomly a...

Arterial blood collected from sheep was analyzed for various amino acids to evaluate effects of dietary forage characteristics on adequacy of amino acid availability for protein synthesis. In three experiments with grass diets consumed Ž . ad libitum or in limited quantities by nearly mature wethers, differences in grass source and or quality generally did not Ž markedly affect arterial concent...

1. The efficiency of utilization of the dietary energy and nitrogen contained in a dried lucerne (Medicago sativa cv. Chartainvilliers) given either chopped (CL) or ground (1.96 mm screen) and pelleted (PL), was measured in a comparative slaughter experiment. Growing lambs were given equal amounts of digestible energy in the chopped or pelleted form at each of the three planes of nutrition for ...
