The objective of this study was to determine the effects of a homolactic acid inoculant on ensiling characteristics and nutritive value of high dry matter (DM) alfalfa. The ensiling characteristics were determined by ensiling inoculated and untreated alfalfa haylage in mini-silos for 0, 2, 4, 8, 16 and 45 days. Two lactating cows fitted with ruminal fistulas were used to determine ruminal degra...

The objectives of this study were to investigate the effect of a saponin-based surfactant, Grain Prep surfactant (GP), and hot flake aging time on starch characteristics and ruminal DM and starch degradability of steam-flaked corn grain. In 2 experiments, the moisture content of incoming corn was automatically adjusted using the Grain Prep Auto Delivery System to 19.8% (Exp. 1) and 18.5% (Exp. ...

Correlations between kernel vitreousness and ruminal in situ (RDMD) and total tract dry matter (TDMD; sum of ruminal in situ and post-ruminal in vitro measurements) degradabilities were determined for 33 diverse corn germplasm sources. These included a wide range of endosperm characteristics from opaque 2 (o2) types to densely packed flint types, and a number of intermediates. Harvests were don...

the aim of this study was to evaluate the effects of chemical treatments including urea (5%), ammonia (3.5%), calcium hydroxide (4%), sodium hydroxide (5%), sulphuric acid (5%) and hydrogen peroxide (5%) on ph, dm solubility, lignin, silica, phenolic compounds, cellulose and hemicellulose stucture and ruminal degradability of rice straw. after processing, the treated straw was ensiled for 1 mon...

Three Holstein steers in the growing phase, each with a ruminal cannula, were used to test the hypothesis that the synchronization of the hourly rate of carbohydrate and nitrogen (N) released in the rumen would increase the amount of retained nitrogen for growth and thus improve the efficiency of microbial protein synthesis (EMPS). In Experiment 1, in situ degradability coefficients of carbohyd...

turity, the degradability of stems, and to a lesser degree leaves, is further depressed by lignification of primaryBecause of the complexity of plant cell wall biosynthesis, the mechwalled parenchyma and epidermal tissues (Wilson and anisms by which lignin restrict fiber degradation are poorly understood. Many aspects of grass cell wall lignification and degradation Hatfield, 1997). These reduc...

Abstract Unlocking browse species in semi-arid regions can be a key to improving the livestock productivity. The research was conducted assess variation chemical composition and vitro dry matter degradability as influenced by seasonal (summer winter) changes. Leaves from ten randomly selected browsable trees sixteen ( Vachellia karroo , Senegalia nigrescens nilotica Balanites maughamii Berchemi...
