ASAS/ADSA Forages and Pastures: Grazing and Alternative Forages
An experiment was conducted to determine animal performance and gain/ha of beef steers (mean initial wt.: 241 kg) grazing a conventional sorghum x sudan hybrid (C) versus its near isogenic brown midrib (BMR) variety. The experiment was conducted during the summers of 1999 and 2000 in the Texas Panhandle. During both summers 8 pasture plots (2.2 ha) were blocked by location and randomly assigned...
متن کاملUnderstanding Nutritive Value: Alternative Forages
There is a tendency to consider forages largely in terms of their energy value or TDN. However, the feeding value of forage is actually a more complex function of its nutrient composition, chemical-physical characteristics of its fiber, acceptability (palatability), and associative interactions it might have with other dietary ingredients. Because forages are not usually cost-competitive with c...
متن کاملCan Organic Materials Reduce Excess Nutrient Leaching from Manure-Rich Paddock Soils?
Horse paddocks have been identified as a significant contributor of animal waste nutrients to natural waters; thus, modified paddock management is needed. Because chemical amendments pose a health risk to horses, an alternative for reducing nutrient translocation from manure is to add available organic residues to the soil. To examine the feasibility of outdoor use of organic materials to reduc...
متن کاملFutility in Complementary and Alternative Medicine: A Critical Review from an Ethical Perspective
Several definitions for medical futility has been proposed in the literature. Medical futility is defined as the condition in which an intervention, either for diagnosis, prevention, treatment, rehabilitation or other medical goals, has no benefit for the individual patient. This critical review aimed to increase the understanding of physicians and other healthcare providers on the issue of fut...
