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 کاملChemical composition, fermentation characteristics, digestibility, and degradability of silages from two amaranth varieties (Kharkovskiy and Sem), corn, and an amaranth-corn combination.
Amaranth ( sp.) is a C plant adapted to poor soils and regions with limited rainfall and high temperatures. The plant is characterized by a yield of up to 85 t/ha, CP concentration of up to 28.5% of DM, and DM digestibility of 59 to 79%, which may vary depending on the species and variety. The potential of this plant as a forage source for ruminants has not been completely considered. This stud...
متن کاملSilage fermentation attributes and certain rumen parameters in sheep fed two grass silages harvested at different stages of maturity
The aim of this study was to compare two tropical grass species, Panicum maximum and Digitaria eriantha, in terms of silage fermentation attributes and certain rumen fermentation characteristics of silage made either at the boot or full bloom stages of growth. A lower silage pH was recorded for the D. eriantha than for the P. maximum silage. Neither species nor maturity stage had a significant ...
متن کاملChemical and physical characteristics of corn silages and their effects on in vitro disappearance.
Estimating the available energy in corn silage provides a unique challenge because the silage contains variable proportions of grain and stover, each of which can differ in availability due to chemical composition and physical form. The objectives of this study were to investigate relationships among chemical components and their relationships with in vitro disappearance of ground and unground ...
متن کاملCell wall chemical characteristics of whole‐crop cereal silages harvested at three maturity stages
BACKGROUND In cooler climates such as found in Scandinavian countries cereals are important feedstuffs for ruminants often ensiled as whole-crop cereal silages (WCCS) to preserve nutrients. Animal performance varies with the type of cereal forage and stage of cereal development being ensiled. Cell wall isolation and analysis was undertaken to determine differences among cereal silages harvested...
