Marketing Hay by Nutritive Value and Weight
Introduction The use of hay-only winter feeding programs is expensive and contributes significantly to the overall cost of cow ownership. Producers should examine the use of alternative winter feeding strategies that reduce the dependence on hay and reduce input costs for the cow-calf production system. A backup plan, however, for the inevitable drought or ice/ snow cover days will require a st...
متن کاملFibrolytic enzyme and ammonia application effects on the nutritive value, intake, and digestion kinetics of bermudagrass hay in beef cattle.
The objectives were to compare the effect of exogenous fibrolytic enzyme (Biocellulase A20) or anhydrous ammonia (4% DM) treatment on the nutritive value, voluntary intake, and digestion kinetics of bermudagrass (Cynodon dactylon cultivar Coastal) hay harvested after 2 maturities (5- and 13-wk regrowths). Six individually housed, ruminally cannulated Brangus steers (BW 325 ± 10 kg) were used in...
متن کاملEffects of supplemental alfalfa hay on feed intake and digestion by Holstein steers consuming high-quality bermudagrass or orchardgrass hay.
Effects of level and frequency of supplementation with alfalfa (A) on feed intake and digestion by steers fed bermudagrass (B) or orchardgrass (O) were determined in two Latin square experiments. In Exp. 1, six Holstein steers (224 kg) were fed B (2.25% N; 71.4% NDF) or O (2.52% N; 64.3% NDF) with 0, 15 or 30% (DM) A (2.70% N; 44.0% NDF). Total DMI was 2.43, 2.72 and 2.85% BW for B and 2.98, 3....
متن کاملDry matter intake and digestion of alfalfa harvested at sunset and sunrise.
The preference exhibited by animals in selecting one feed over another is important only if the preferred diet is consumed daily in larger quantities, digested to a greater extent, or both. Six alfalfa (Medicago sativa L.) hays were harvested in pairs at sunset (PM) and sunrise (AM) on consecutive days at three harvest dates. A previous study of these hays demonstrated differences in ruminant p...
متن کاملevaluation of nutritive value of grass pea hay in sheep nutrition and its palatability as compared with alfalfa
the nutritive value of grass pea (lathyrus sativus l.) hay was evaluated based on its chemical composition, gas production, fractioning of protein in cncps and afrc systems, metabolizable energy (me), rumen degradability through in situ technique and in vitro digestibility through tilley and terry method. the crude protein (cp), neutral detergent fiber (ndf) and acid detergent fiber (adf) value...
