Effects of Forage Management on Pasture Productivity and Phosphorus Content
The objectives of the current study were to determine the amounts of aboveand below-ground plant biomass production, P uptake by forage, and P concentration of cool-season grass forage as influenced by management and season. Five forage management treatments were evaluated over 3 years in smooth bromegrass (Bromus inermis Leyss) pastures. Management practices were: ungrazed (U), hay harvest/fal...
متن کاملHeat Damaged Forages: Effects on Forage Quality
Traditionally, heat damage in forages has been associated primarily with alterations in forage protein quality as a result of Maillard reactions. A Maillard reaction is a heat-induced chemical reaction between protein (amino acids) and sugars. Maillard products produce a range of odors and colors in forages, but generally are poorly characterized nutrients in ruminant nutrition. Terms such as h...
متن کاملImpact of defoliation intensity and frequency on N uptake and mobilization in Lolium perenne.
The aim of the study was to evaluate the impact of defoliation intensity, defoliation frequency, and interactions with N supply on N uptake, N mobilization from and N allocation to roots, adult leaves, and growing leaves. Plants of Lolium perenne were grown under two contrasted N regimes. Defoliation intensity treatments consisted of a range of percentage leaf area removal (0, 25, 50, 75, or 10...
متن کاملForage and Pasture Management for Laminitic Horses
In the past, many cases of laminitis have been of mysterious origin. Recent investigations in veterinary medicine, coupled with the availability of new techniques for analyzing hydrolyzable carbohydrates in forage may provide evidence to solve some of these mysteries. Fructan has been shown to be capable of inducing laminitis in clinical studies. Insulin resistance, a primary feature of Equine ...
متن کاملthe effects of sowing rate, defoliation intensity and time of defoliation commencement on vegetative and reproductive growth of medic swards
to obtain detailed information of sowing density and defoliation intensity under more controlled conditions on herbage production and seed yield, paraggio medic was grown on raised-beds located outdoors at the waite agricultural research institute. a split split randomised block design was used. treatments comprised three sowing rates (densities): low (3 kg/ha), medium (15 kg/ha) and high (...
