Intake and Digestibility of Corn Silages
T HE feeding of corn silage has long been a common practice in corn producing areas; however, the effect of cultural practices on nutritive value has received only minor attention. Some important factors are: stage of maturity (Huber, Groff and Engel, 1965), varieties (White et al., 1924), plant population (Nevens, 1951; Alexander et al., 1963) and soil fertility (Alexander et al., 1963). Since...
متن کاملIn situ Rumen Degradation Characteristics of Maize, Sorghum and Sorghum-Sudan Grass Hybrids Silages as Affected by Stage of Maturity
This research was conducted to investigate in situ degradation characteristics of maize, sorghum and sorghum-Sudan grass hybrids. whole plant of maize (TTM-815, DK-711), sorghum (SS-506, FS-5) and sorghum × Sudan grass hybrids (P-988, Grazer N2) were grown under semi-arid conditions and harvested at different maturity stages (mid-flowering (MF), milk-line (ML) and hard-dough (HD)) and ensiled. ...
متن کاملEffects of chewing behavior and ruminal digestion processes on voluntary intake of grass silages by lactating dairy cows.
Four primiparous Holstein-Friesian cows (518 kg average BW) with ruminal and duodenal cannulas were used to examine voluntary intake of direct cut (DC) or wilted (W) grass silage in relation to ruminal characteristics and chewing behavior. Dry matter content of the silages was 17.0 and 38.1%, concentrate DM intake was restricted to 5.0 and 5.3 kg/d, and voluntary DM intake from silages averaged...
متن کاملRuminal fermentation and intestinal flow of nutrients by lactating cows consuming brown midrib corn silages.
Rumen characteristics and digestive kinetics of brown midrib corn silage were evaluated with five late-lactation (221 DIM +/- 20 d) multiparous cows fitted with ruminal and duodenal cannula. Dietary treatments were applied by using a single reversal design with two 21-d periods where either brown midrib (BM3) or isogenic (ISO) corn silage were included in a total mixed ration formulated to be 4...
متن کاملComparison of feeding corn silages from leafy or conventional corn hybrids to lactating dairy cows.
Three corn hybrids (Pioneer 36F30, Mycogen TMF2450, and Mycogen TMF2404) were compared for yield and quality traits, and lactation performance and apparent digestibility by Holstein cows. The three corn silages were harvested at a target of 33 to 35% dry matter. Before harvest, six corn plants were randomly selected for plant fractionation. Grain-to-stover ratios were 0.92, 0.70, and 0.95 for t...
