Diet Manipulation Can Be Used to Reduce Odor
Nutrient input reduction and nutrient form modification have been shown to be helpful in reducing odor, ammonia levels, hydrogen sulfide levels, and dust and particulates. By providing nutrient inputs that are suited to the needs of the animal, overfeeding nutrients is avoided, and in turn, reduces the amount of excreted nutrients. Utilizing phase feeding, lowering crude protein, or adjusting grind particles size are just several feed management and diet formulation practices which have been shown to reduce emissions. Benefits include; impacting multiple emissions, easy implementation when working with a nutritionist, and in many cases, the changes may cost very little. However, the availability of additives, feedstuffs, and the costs may fluctuate. More information about diet manipulation can be found on the Air Management Practices Assessment Tool website.
Dairy Month and Dairy Manure
Dairy month, a great excuse to nibble on some ice cream with strawberries, rehydrate with a glass of ice cold milk, or to behold the power of cheese. But in this newsletter, it also means it’s a chance to think about the back end of the cow and the manure. This year we decided to take a stroll down memory lane to see how improvements in milk production and changes to manure characteristics have changed over time. We also wanted to see what it means for sustainability. Milk production per cow has increased dramatically, while manure production has slowly increased. Today’s dairy cow produces less manure per gallon of milk than ever before. Check out the details on The Manure Scoop.
Animal Agriculture Education Project Launched
The EPA recently launched the Animal Agriculture Education Project, which is a series of educational modules featuring videos, virtual farm tours, and discussion topics including manure management decision-making and water quality protection measures. The Animal Agriculture Education Project is accessible on the Livestock and Poultry Environmental Learning Center website.
