A year-round grazing system for springand fall-calving cows was developed to compare animal production and performance, hay production and feeding, winter forage composition changes, and summer pasture yield and nutrient composition to that from a conventional, or minimal land system. Systems compared forage from smooth bromegrass-orchardgrass-birdsfoot trefoil pastures for both systems in the ...

Two trials were conducted to determine the effect of energy source (ENG) and ruminally degradable protein (RDP) on lactating cow performance and intake and digestion in beef steers. In Trial 1, 78 cow-calf pairs were used in a 2 x 2 factorial design to determine the effect of ENG (corn or soyhulls; SH) and RDP (with our without sunflower meal) to a forage diet for lactating beef cows. The basal...

BACKGROUND Efficient conversion of lignocellulosic biomass to fermentable sugars requires the synergistic action of multiple enzymes; consequently enzyme mixtures must be properly formulated for effective hydrolysis. The nature of an optimal enzyme blends depends on the type of pretreatment employed as well the characteristics of the substrate. In this study, statistical experimental design was...

sainfoin (onobrychis sativa), a forage legume, is worth attention because of its production and superior quality among pasture and hay forage crops in iran. sainfoin forage yield may be reduced by different levels of salinity. increasing forage yield in saline environments through plant breeding could partially compensate for this shortcoming if sufficient genetic diversity and heritability be ...

Alfalfa hay utilization by dairy cattle has expanded in western dairy states. Alfalfa silage utilization has increased in the Midwest. Alfalfa haylage contains high levels of nonprotein nitrogen (NPN) due to protein breakdown during fermentation. Excessive levels of NPN in alfalfa silage diets require supplementation of protected protein sources to meet protein demands of high-producing cattle....

just below the soil surface, such as crown buds or rhizomes, aids plant tolerance to fire. Timing of spring fire and glyphosate [N-(phosphonomethyl)glyFire may not be an option for managing warm-season cine] treatments is critical to control weeds without compromising grasses in densely populated areas of the northeastern production of warm-season grasses. To determine the forage and seed USA w...

Hay preservatives such as acids, bacterial inoculants, enzymes and other compounds, allow for hay to be baled at higher moisture levels (18-25%), thus decreasing field drying times. Baling at higher moisture means that there will be reduced in-field dry matter (DM) and leaf loss. While preservatives do not add anything in terms of nutritive value, they prevent heating and mold development if ha...
