Organic bedding materials are getting more difficult to obtain. As a result, there has been recent interest in the upper Midwest in using recycled manure solids for bedding. At the recent annual National Mastitis Council meeting in New Orleans, there was a session on bedding management – using recycled manure. Presenters included Kenn Buelow, a producer veterinarian from Wisconsin; Peter Ostrum, a veterinarian from New York State; and myself. My goal as the first presenter was to give an...
Feeding more phosphorus (P) than recommended won't improve your milking herd's milk yield or reproductive performance. There is, however, a major benefit to your pocket book and the environment when you don't over-feed this nutrient to your dairy cows. According to the Canadian Food Inspection Agency's Feed Act, the minimum dietary P requirement for dairy cattle is 0.30 per cent of dry matter intake (DMI). The U.S. National Research Council (NRC) calculates that P should make up 0.33...
The nitrogen, phosphorus and potassium (N, P, K) content of dairy manure will vary depending on the animal's growth stage, production performance and ration formulation. Dave Fischer, University of Illinois Extension animal systems educator, says the dietary effects of dairy cattle rations as it relates to N and P excretion needs to be better understood by producers and industry personnel. Researchers from the University of Florida have observed that the predicted excretion of...
Compost dairy barns, otherwise known as sawdust or bedded pack barns, have been around for a few years now. They have proven to be a good choice for many producers as they have solved many cow comfort problems that have plagued conventional freestall barns for years. The producers that have these barns have been challenged by increased costs of bedding materials, namely sawdust. However, prices have stabilized for now and current costs are around $0.65 per cow per day. Producers have really...
Bark beds were one of four types of milk house wastewater treatment systems designed, installed and monitored on Minnesota dairy farms as part of two EPA 319 Grant funded projects administered through the Minnesota Pollution Control Agency (MPCA). The effort, which began in 2002, required significant funding and collaboration by other federal, state and local agencies, and the cooperating dairy producers. A bark bed is a soil infiltration area covered with bark or wood shreds where...
Surface irrigation was one of four types of milk house wastewater treatment systems designed, installed and monitored on Minnesota dairy farms as part of two EPA 319 Grant funded projects administered through the Minnesota Pollution Control Agency (MPCA). The effort, which began in 2002, required significant funding and collaboration by other federal, state and local agencies and the cooperating dairy producers. Surface irrigation systems distribute milk house wastewater at agronomic...
Every dairy generates milk house wastewater. Dairy producers must decide how to handle their milk house wastewater in an environmentally appropriate and economical way that fits their management. This is the first article in a series that will describe two EPA 319 Grant funded projects administered through the Minnesota Pollution Control Agency (MPCA) that evaluated four types of milk house wastewater treatment systems. These projects were a team effort. Additional significant funding and...
If the average cow produces 100 pounds of manure a day, how does a dairy farmer manage all the excess waste? Tom Herlihy, an agricultural engineer, created a unique and environmentally friendly technology to deal with this very problem. Herlihy owns and operates RT Solutions Inc., which employs 8 million earthworms in a state-of-the-art facility to transform manure into an environmentally friendly, all organic fertilizer called Worm Power. Worm Power benefits from its...
A new cleaning service for dairy manufacturing can reduce the operating expenses and environmental impacts of processing, its manufacturer claims. Tetra Pak says it latest "Product and Water Saving" scheme can help to better control water and product loss during Cleaning In Place (CIP) by measuring and amending individual aspects of the process. As increasing raw material and production costs continue to ebb away at the dairy industry's margins, processors are under greater...
Wagner Dairy in Middleton, Wisconsin is a prime example of how Pro-Act Microbial's technology has not only helped them in the past but is partnering with them to usher in the future of dairying. Wagner Dairy will be installing the Pro-Act's ITS (Ideal Treatment System) by enhancing their current Pro-Act system with the addition of two processing tanks. This green technology facilitates the collection of biogas and provides farmers with options to manage the nutrients. Pro-Act's research has...
A waste digester that can separate water from cow manure on a farm in New Mexico is believed to be the first of its kind aimed at restoring clean water. The Raymond L. Jarrett farm, which has 400 cows in Los Lunas, has been awarded $64,686 to treat the cows' wastewater and reuse it to irrigate fields and recharge aquifers, the Santa Fe New Mexican reported Tuesday. The digester is one eight projects sharing $274,000 in grants from the U.S. Natural Resources Conservation Service....

Raising dairy heifers to an adequate size and with an age at first calving between 22 and 24 months can optimize profitable milk production. This achievable goal requires proper nutrition and feeding management so heifers are large enough to breed at 13 to 15 months of age. On many dairy farms, heifer management is not the most critical part of the day-to-day activities; however, chronic neglect of nutrition, feeding management, and preventative health care can lead to stunted growth....
Scientists at eight universities are conducting the largest-ever study of air emissions at the nation's hog, dairy and poultry farms.
The study, which scientists hope will help improve methods of estimating any given farm's emissions, began this summer and will take an estimated 2 1/2 years to complete. It will measure levels of hydrogen sulfide, ammonia, nitrous oxide, particulate matter and other substances wafting from livestock buildings and manure lagoons at 20 farms in nine states....
Major players within the dairy industry are beginning to witness unwanted reminders of the high cost climate change could have on their operations, as prices for raw materials like milk continue to soar. Over the last year in the UK alone, the price of wholesale milk has doubled, while the value of cream has also shot by 23 per cent, according to figures by the national milk council. These increases are mirrored in supply chains across the world with the typical price in...
Animal-rearing facilities may soon be taking a cue from human hygiene. An Agricultural Research Service (ARS) scientist in Fayetteville, Ark., has found that aluminum chloride—a common ingredient in deodorant sticks—helps minimize the nose-prickling vapors that tend to concentrate in and around swine and dairy facilities.
The compound, as soil scientist Philip A. Moore, Jr., discovered, can also significantly slash troubling ammonia emissions that are typically generated when hundreds of...
Four Indiana dairies, connected by family history and geography, have jointly signed an historic agreement with Environmental Credit Corp. (ECC) to create more than one million carbon credits from greenhouse gas-reducing projects. Each credit is equivalent to one metric ton of carbon dioxide prevented from entering the atmosphere. The farms' greenhouse gas reductions are comparable to planting four million deciduous trees or offsetting the emissions of 20,000 cars.
