A series of 33 digestion experiments was conducted in which the effect level intake upon digestibility forages and mixed diets studied. Within ranges examined, fresh, green by wethers hays steers not affected intake. In two with markedly decreased as consumption increased. However, one same other Although data obtained do provide an explanation for difference responses obtained, it noted that depressed increasing intakes were those older animals employed. depression ration greater younger...
Six alfalfa ( Medicago sativa L.) cultivars, ‘DuPuits,’ ‘Ladak,’ ‘Lahontan,’ ‘Ranger,’ ‘Uinta,’ and ‘Vernal’ were selected for low high saponin concentration tested at various locations seven agronomic traits resistance to six diseases, five insects, two nematodes. Although the selection was effective, none of (yield, foliage color, frost damage, lodging, digestibility, fraction I protein, soluble protein) consistently affected by selection. High retarded in vitro growth southern blight...
A relatively pure stand of first-growth Climax timothy was divided into 11 plots and harvested at stages maturity beginning on May 27, 7-day intervals until August 5. Protein content protein digestibility both decreased sharply with each delay in harvest July 22 when values seemed to level off remained fairly constant, probably due the effects bottom regrowth forage possibly seed formation. The energy these forages markedly as they matured. Coefficients dry matter constantly harvest, a...
Abstract The 2022 student debates of the Entomological Society America (ESA) happened during Joint Annual Meeting Societies America, Canada, and British Columbia in Vancouver, BC, addressed entomological aspects beyond research education. Student Debates Subcommittee ESA Affairs Committee participating team members communicated for 8 months prepared debates. theme meeting was “Entomology as inspiration: Insects through art, science, culture”. There were 2 unbiased speakers who introduced...
Abstract Delayed cutting during the practical harvesting season of first‐growth forages raised in humid climates has resulted a linear decline digestibility component nutritive value. This study considered effect date upon and intake components value first growth alfalfa ( Medicago sativa L.) under irrigated conditions at two altitudes Utah Montana. Duration was 5 years with harvests occurring over ranges 23 to 62 days. Intake by total collection each hay were determined four sheep....
ABSTRACT A near infrared reflectance (NIR) spectrophotometric procedure was evaluated for potential use in assaying nutrient contents of vegetables. Dried ground samples cauliflower, broccoli, Brussels sprouts, spinach, asparagus, peas, green beans, and squash were analyzed chemically crude protein, fat, ash, neutral detergent fiber (NDF) then scanned to develop NIR prediction equations. For the 75 calibration foods samples, respective correlation coefficients between actual predicted values...
A near-infrared-reflectance (1R)spectroscopic method was evaluated for potential usage in predicting soluble N, total N and some fibrous fractions crested wheatgrass, Agropyron crktdum (L.) Gaertn., A. uksertorum (Fisch.ex Link), et al.The correlation coefficients (r) between IR 0.15N NaCl (N Sal), 10% Burroughs Mineral Mixture solution (NBMM), neutral detergent fiber (NDF), acid (ADF), lignin (ADL) 84 samples were 0.95,0.90,0.70,0.90,0.82,and0.72, respectively.The technique provided a...
Six pea aphid [ Acyrthosiphon pisum (Harris)]‐resistant (PAR) and five aphid‐susceptible (PAS) alfalfa ( Medicago sativa L.) varieties were compared for foliage root saponin concentration, forage yield, lodging, color, resistance, in.vitro digestibility, clover curculio Sitona hispidula (F.)] resistance. The PAR characterized by higher yields, but lower digestibility than the PAS under noneconomic levels of infestation. When yields hay corrected had an advantage 0.9 metric ton/ha over...
