“…Grass–legume mixtures contribute to a balance of energy and protein and sustain herbage mass to help meet the nutritional requirements of most grazing livestock (Papadopoulos et al ., ). Often times, supplemental feeds are used to help meet dietary requirements and improve nutrient‐use efficiency for maximal performance of sheep and goats.…”

We evaluated forage production patterns, weight gains and blood parameters when lambs (Ovis aries) and meat-goat (Caprus hircus) kids were finished on a mixed sward of cocksfoot (Dactylis glomerata L.), red clover (Trifolium pratense L.) and white clover (Trifolium repens L.) with (SUP) and without (UNSUP) supplemental whole cottonseed (Gossypium hirsutum; WCS) in a replicated study. Botanical composition and energy/protein ratios of the sward varied with year and with time during the growing season. Swards had greater amounts of red clover relatively early and more cocksfoot later in the season. Suffolk (SX) lambs had the heaviest body weights, Katahdin (KA) lambs were intermediate, and meat-goat (GX) kids were the lightest at the end of each year. Overall body weight gain followed a trend of SX > KA > GX, and WCS supplementation increased weight gain for all animals by 18%. Only in 2008 did SUP animals have higher blood urea nitrogen levels, which may indicate less efficient use of dietary nitrogen when grazing grasslegume pastures managed for high nutritive value compared with UNSUP animals. Gossypol in WCS did not affect blood packed cell volume between SUP and UNSUP lambs and meat-goat kids. Suffolk lambs, Katahdin lambs and cross-bred Boer meat-goat kids finished on pasture with and without WCS supplementation produced desirable body weights for most ethnic markets in the USA.

Alfalfa herbage at the vegetative to early-bud stage of growth was simultaneously fed to cattle with alfalfa-grass mixtures containing 25, 40 or 50% orchardgrass. At all three levels of orchardgrass, there was either complete prevention of bloat or it was substantially reduced. Alfalfa alone yielded 334 cases of bloat as compared to 25 for the mixtures. During the warmest and driest intervals, bloat was reduced only by one-third when the feed alfalfa contained 25% orchardgrass. Quand la ration ne contient que 25 % de dactyle, le nombre de cas de météorisme n'est amputé que du tiers durant les périodes les plus chaudes et les plus arides.

Understanding the growth dynamics of grass–legume swards is critical as pastoral management practices are adapted to varying economic constraints and emerging environmental considerations. Efficient management must synchronize the use of accumulated herbage with the needs of grazing livestock. This must be accomplished against the dynamic background of within and among year weather patterns interacting with herbage growth and grazing animal behavior. In the Appalachian region of the eastern United States, pastures often are dominated by orchardgrass (Dactylis glomerata L.) and white clover (Trifolium repens L.). We determined botanical composition and herbage productivity of orchardgrass and white clover swards during four consecutive years when managed as a function of canopy development and regrowth interval. Productivity was influenced by defoliation practices when mixtures were managed according to canopy development. Productivity was greatest when swards were managed as hay or when clipped to a 5‐cm residue each time mean canopy height reached 20 cm. White clover declined and orchardgrass increased in the sward irrespective of defoliation treatment. Botanical composition of mixtures with the erect growing orchardgrass tended to be more stable, whereas swards including the decumbent orchardgrass tended to be invaded by weeds. Some increase in productivity occurred during the first growing season when mixtures were clipped at either 2‐ or 4‐week intervals. Regardless of defoliation practice, white clover, and in some instances orchardgrass, presence declined during two consecutive growing seasons with various other volunteer grasses and forbs contributing to productivity. Productivity and persistence of sown sward components may be less dependent on management practices than on the expression of interactions responding to within and among year weather patterns.
