For horse enthusiasts, veterinarians and operators of boarding stables, handling and disposing of horse manure can pose numerous challenges. Frequently, operators of equine facilities and large-animal veterinary clinics must pay someone to take the manure off the property. However, there is an excellent way to stimulate demand for a product that would otherwise be a liability. Composting manure can eliminate a messy problem and… Read More →

Use of cationic polymers to reduce pathogen levels during dairy manure separation

Posted on by

(View original article)  Various separation technologies are used to deal with the enormous amounts of animal waste that large livestock operations generate. When the recycled waste stream is land applied, it is essential to lower the pathogen load to safeguard the health of livestock and humans. We investigated whether cationic polymers, used as a flocculent in the solid/liquid separation process, could reduce the pathogen indicator load in the animal waste stream. The effects of low charge density cationic polyacrylamide (CPAM) and high charge density cationic polydicyandiamide (PDCD) were… Read More →

Composting Large Animal Carcasses

Livestock producers and large-animal veterinarians face a growing problem in rural Texas—what to do with dead animals. Rendering services are getting more expensive and harder to come by, and just leaving carcasses to predators and the forces of nature is not acceptable. So what are the options? Except for poultry, you can bury dead animals as long as you do not pollute ground or surface water. Incineration, biodigestion and chemical digestion are other disposal methods, but they are expensive, complicated or both. Composting is a simple, low-cost disposal… Read More →
