  • Zone tillage depth affects yield and economics of corn silage production

    Increasing numbers of dairies in northeastern United States are classified as confined animal feeding operations (CAFOs). Many dairy farmers in New York (NY) abandoned conventional and adopted zone tillage (ZT) in 4-yr corn (Zea mays L.) silage-alfalfa (Medicago sativa L.) rotations on highly erodible land to comply with NY CAFO plans. Farmers now question optimum ZT depth because of increased ...

  • Performance of lactating dairy cows fed macerated forage conserved as silage and hay case study

    The effect of forage maceration at harvest on silage characteristics and its effects on lactation performance of Holstein cows were determined. Either a roller conditioner or a prototype forage macerator manufactured by PA-MI were used to cut a 25-ha field of alfalfa (Medicago saliva) forage. The harvested forage was wilted and preserved as silage or hay. Maceration of alfalfa forage resulted in ...


  • Polyphenol, conditioning, and conservation effects on protein fractions and degradability in forage legumes

    Forage legume proteins were fractionated by the Cornell Net Carbohydrate and Protein System or ruminally incubated to assess how conditioning and conservation methods interact with polyphenols (condensed tannins or o-quinones) to alter protein degradability. The presence of polyphenols, conditioning by maceration rather than rolls, and conservation as hay rather than silage shifted protein ...

  • Dietary forage impacts on dairy slurry nitrogen availability to corn

    Precise feeding of protein and mineral supplement can maintain high levels of milk production and reduce nutrient excretion in dairy manure and losses to the environment. No information is available on the impacts of feeding different silages to dairy cattle (Bos taurus) on manure N cycling in soils. Slurry from dairy cattle fed rations containing alfalfa (Medicago sativa L.; ALF), red clover ...

  • Composting Livestock Mortalities

    Performance, composting methods, environmental impacts and biosecurity of the process are evaluated for emergency disposal of cattle by research team at Iowa State University. A THREE-YEAR study was commissioned by the Iowa Department of Natural Resources to evaluate the practical feasibility, performance, environmental impacts and biosecurity of using composting for emergency disposal - should a ...

  • California company closes the composting loop

    BEFORE we made our first ton of compost, we had already talked to farmers to determine what they needed in a soil amendment,” says Roger Van Der Wende, Vice President, Supermarket Division, Community Recycling & Resource Recovery, Inc. (Community) in Sun Valley, California. Considering the fastidious navigation the company has done to advance in a previously uncharted realm of resource ...
