  • 3 Tips on How to Keep Dairy Barns Bird-Free

    Controlling birds around farm buildings can take time out of your already strict daily routines. Nuisance birds like pigeons, starlings and barn swallows don’t care about anyone’s schedule but their own. Unfortunately, sharing the barn with pest birds isn’t sanitary and the costs and dangers of birds in dairy and livestock operations can add up quickly!

  • Effects of reducing dietary nitrogen on ammonia emissions from manure on the floor of a naturally ventilated free stall dairy barn at low (0–20°C) temperatures

    Received for publication December 30, 2008. This study was conducted to determine the potential for reducing ammonia (NH3) emissions from manure deposited on the floor of a naturally ventilated free stall barn by mid-lactation dairy cows fed reduced or normal N diets. Two crude protein (CP) diets (178 g kg–1 [high] and 159 g kg–1 [low] dry matter ), were used. The diets were fed to 48 Holstein ...

  • Bull Calves Need Care Too

    By far, most bull calves will never become a lasting benefit to a dairy herd, and as such may not always receive the same level of care that heifer calves do. Harmonizing your calf rearing programs will yield positive results for all calves and your bottom line. All calves require excellent care, especially in the first few days of life. Without adequate, timely colostrum and proper ...

  • Industry Takes Shape: Why Digesters Make Dollar Sense Now

     THIRTY years ago, when I was a college student studying ways to convert manure to electricity, we speculated that the 1970s would be the decade of the innovators, the 1980s for the launch of operating projects, and the 1990s when the mainstream adopted the technology. Now I think our predictions for the mainstream were ten to 15 years premature — but it is happening! During the 1990s, the ...

  • Ohio Targets Food Residuals Composting

    WHILE RECYCLING of paper and yard trimmings has grown rapidly in Ohio in the last 30 years - now up to 50 percent for paper and 62 percent for green materials - the recovery rate for food residuals is at less than three percent. To turn things around, the Ohio Environmental Protection Agency (OEPA) and the Ohio Department of Natural Resources' (ODNR) Division of Recycling & Litter Prevention have ...

  • Redefining ag-wastes as coproducts

    Alan Doering doesn’t have the word “waste” in his vocabulary. As the scientist heading up the Agricultural Utilization Research Institute’s (AURI) coproduct utilization program, Doering sees crop residue, agricultural processing leftovers and biomass as products with value worth exploring. “Every leftover or coproduct has a value,” Doering says. “Our goal is to find the best use with the highest ...

  • Renewables Make Progress on Many Fronts: Grass Roots Ethanoll from Field Waste

    Progress in community digesters will bring fresh jobs and local control back to farm country - plus offering answers for global warming. FROM THE MIDWEST where native grasses, field waste and wood chips are fueling new biorefineries that are locally-owned to the Northwest where some 50 million gallons of raw manure are producing electricity and dried bedding, community digesters and on-farm ...

  • Cost-Benefit Analyses: Exploring the Economics of On-Farm Composting

    When exploring the merits of on-farm composting, the question most often raised is: What are the economics? How do the savings or revenues from on-farm composting compare to the costs? Of course, the answer is the ever present “it depends.” Expenses, resources, revenue opportunities, environmental constraints and circumstances vary greatly from one farm to the next. Most people would agree that ...

  • Rake In Greater Capacity And Higher Hay Quality

    It’s been said that the steel-toothed dump rake was first introduced in the 1860s. Of course, the process back then was to rake hay into piles, which were then pitched onto a wagon for transport to a haystack or the barn loft. To make windrows for the balers that came later, the operator simply spaced the “dumps” equally so they lined up in the field. The irony is that until ...

  • Financing an anaerobic digester

    LENDERS are generally well disposed to projects that diversify revenues while lowering costs and mitigating risks. Add a ready source of equity and you are well on the way toward financing a project that is a win-win proposition for the lender and the project developer. Such is the case with the anaerobic digester project at Geerlings Hillside Farm (GHF). The Geerlings's 8,000-head hog farm is ...
