regulation) or hormonal signals indicating satiety, a fulfilling of current nutritional requirements (metabolic Neutral detergent fiber (NDF) is considered the laboratory mearegulation) (Van Soest, 1994). The concentration of sure most closely correlated with voluntary intake of forages by rumiNDF is the most common selection criterion to improve nant livestock. The objectives of this study wer...

Three beef cattle diets were assessed for their potential to produce odorous compounds from cattle feces excreted during the growing and finishing periods. Eight pens containing 51 steers of varying proportions of Brahman and MARC III genotypes were fed either a chopped bromegrass hay diet or a corn silage diet for a 119-d growing period. After the growing period, all steers were switched to th...

Maturing reed canarygrass, Russian wildrye, and smooth bromegrass cell walls were analyzed for lignin, phenolic acids, and neutral sugars. Linear correlation between in vitro dry matter digestibility and the p-coumaric acid content was .86 . The correlation between in vitro dry matter digestibility and ratio of p-coumaric to ferulic acid was .84 . Samples with high percentages of lignin also co...

The efficacy of vegetative buffer strips (VBS) in removing herbicides deposited from surface runoff is related to the ability of plant species to promote rapid herbicide degradation. A growth chamber study was conducted to compare C-atrazine (ATR) degradation profiles in soil rhizospheres from different forage grasses and correlate ATR degradation rates and profiles with microbial activity usin...
