The effects of Lactobacillus plantarum on chemical composition, rumen degradability, in vitro gas production and energy content of whole-plant corn ensiled at different stages of maturity
This study was carried out to determine the effects of Lactobacillus plantarum on chemical compositionand nutritive value of whole-plant corn (WPC) ensiled at different stages of maturity. Based on local routinepractice, WPC was harvested at three stages of maturity as follows: (1) two weeks before routine harvestingtime; (2), one week before routine harvesting time and (3), routine harvesting ...
متن کاملRelationship between corn vitreousness and ruminal in situ starch degradability.
The objective of this experiment was to determine the relationship between corn kernel vitreousness and ruminal in situ starch degradation. Fourteen U.S. and five Brazilian corn hybrids cultivated in their respective countries were evaluated. The U.S. dent hybrids were harvested at one-half milk line, black layer, and 21 d after black layer stages of maturity. Brazilian flint hybrids were harve...
متن کاملEffect of a saponin-based surfactant and aging time on ruminal degradability of flaked corn grain dry matter and starch.
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. ...
متن کاملDigestibility and ruminal digestion kinetics of corn silage
The in situ dry matter (DM) disappearance of corn silages in two maturity stages (milk grain and half milk line) of known in vivo and in vitro digestibility was determined, with the main purpose of comparing digestibility values with the ruminal disappearance at 24 and 48h of incubation. A secondary goal was the description of their ruminal digestion kinetics, from which the effective degradabi...
متن کاملRelationships between kernel vitreousness and dry matter degradability for diverse corn germplasm II. Ruminal and post-ruminal degradabilities
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...
