Corn Silage Production and Management
Corn harvested for silage is an important feed crop on most Pennsylvania farms, where cropland often is limited. The crop provides livestock producers with a high-yielding, relatively consistent source of forage and the animals with a highly digestible and palatable feed. Corn silage produces more energy per acre than any other crop grown in Pennsylvania. Corn silage serves as a high-energy for...
متن کاملThe Effect of a Silage Inoculant on Silage Quality, Aerobic Stability and Milk Production
A silage inoculant [Biomin® BioStabil Plus, BSP, a blend of Enterococcus faecium (DSM 3530), Lactobacillus brevis (DSM 19456) and Lactobacillus plantarum (DSM 19457)], was used on legume-grass silage [32% of dry matter (DM)] vs. an untreated control silage (CT). The material had mean crude protein (CP) and water soluble carbohydrate (WSC) concentrations of 174 and 88 g/kg,respectively. BSP resu...
متن کاملMaize Silage as Substrate for Biogas Production
The presented work studies the possibilities of using maize silage for biogas production in laboratory as well as in full-scale conditions. From the results of long-term operation of a mixed laboratory anaerobic reactor, it follows that processing of maize silage as a single substrate is an unstable process due to the low alkalinity of silage that has to be compensated by pH adjustment. Specifi...
متن کاملMethane production, digestion, ruminal fermentation, nitrogen balance, and milk production of cows fed corn silage- or barley silage-based diets.
This study evaluated the effects of replacing barley silage (BS) with corn silage (CS) in dairy cow diets on enteric CH4 emissions, ruminal fermentation characteristics, digestion, milk production, and N balance. Nine ruminally cannulated lactating cows were used in a replicated 3 × 3 Latin square design (32-d period) and fed (ad libitum) a total mixed ration (TMR; forage:concentrate ratio 60:4...
متن کاملReplacing alfalfa or red clover silage with birdsfoot trefoil silage in total mixed rations increases production of lactating dairy cows.
The objective of this study was to compare milk production and nutrient utilization in dairy cattle fed silage made from alfalfa (AL) or red clover (RC) versus birdsfoot trefoil (BFT) selected for low, normal, and high levels of condensed tannins. Condensed tannin contents of the 3 BFT silages were 8, 12, and 16 g/kg of DM by butanol-HCl assay. Twenty-five multiparous Holstein cows (5 fitted wi...
