Abstract:
Cattle selectively graze grasses for green, leafy material, often restricting their foraging to localized patches surrounded by large, lightly grazed areas. A two year study was conducted on the Santa Rita Experimental Range in Southern Arizona to compare the effects of heavy grazing on Lehmann lovegrass (Eragrostis lehmanniana Nees.) digestibility. Lehmann lovegrass was clipped from within heavily grazed patches and adjacent ungrazed areas. Green and dry plant materials were separated and analyzed for percentage in-vitro dry matter digestibility (IVDMD). Results indicated a significant differ

Abstract:
Herbivores have a significant role in tundra ecosystem composition and processes. They can cause changes of vegetation composition and nutrient content that result in altered palatability of the vegetation and food availability for herbivores. The direct effect of herbivores on plant quality and quantity have been studied in detail, and recent studies have shown that present vegetation composition and soil processes might show legacies of historical grazing a century ago. This raises the question if historical grazing also has a legacy on the palatability of the vegetation. In this study, I in

Abstract:
Feed intake assessment is a valuable tool for herd management decisions. The use of markers, either internal or external, is currently the most used technique for estimating feed intake in production animals. Three experiments were conducted with beef and dairy cattle. In dairy cows fed a corn silage based diet with 45% concentrate, the average fecal recovery (FR) of TiO2 was higher than FR of Cr2O3 and both FR were more than unity. The FR was unaffected by the fecal sampling procedure but, estimates for dry-matter digestibility (DMD) and fecal output (FO) were affected. The Cr2O3 + indigestib

A series of three experiments were conducted to evaluate different methods of estimating forage mass of tall fescue pastures, and dry matter intake and digestibility in beef steers under indoor and grazing conditions. Forage mass was estimated with the herbage cutting method (HCM) and three indirect methods; the pasture capacitance meter (PCM), the plate meter (PPM), and the visual estimation (VE). The coefficients of determination from the calibration equations were 0.686, 0.751, and 0.862 for the PCM, PPM, and VE, respectively. There were differences in forage mass estimates due to sampling

Abstract:
Extensive sheep farming in South Africa generally imply circumstances where roughage is the primary food source. However, when roughages form the main component in ruminant diets these diets are typically characterised by high fibre, low energy and low nitrogen values. Adding nitrogenous compounds to low-quality roughage not only promote the growth of fibrolytic bacteria, but also enhance digestion rates and microbial protein synthesis. Urea is the nitrogen source most often utilised for supplementing nitrogen as it is relatively inexpensive and proven to be effective. However, the rapid hydro

Little conclusive evidence is, however, available to support this. Explanations as to why such differences may exist are also limited.
