Can Genetic Selection Enhance Nutrient Efficiency?
By Dr Todd See, Swine Genetics Specialist, North Carolina State University - This article looks at the role that genetic selection can have in reducing the amount of nutrients excreted in the urine and faeces of swine in a modern production facility.

Manure Management for Water Quality: Costs to Animal Feeding Operations of Applying Manure Nutrients to Land
By U.S.D.A., ERS - Nutrients from livestock and poultry manure are key sources of water pollution. Ever-growing numbers of animals per farm and per acre have increased the risk of water pollution.

Should nitrogen fertilizer be applied after injected swine manure?
By Brad Van De Woestyne, and Alfred M. Blackmer, professor, Department of Agronomy, Iowa State University - Many farmers question the nitrogen (N)-supplying power of animal manure and apply fertilizer N as insurance against yield losses. Precision farming...

Putting Numbers to Manure
By Jane Messenger and Greg Vincent, Pork Magazine - Putting a value on hog manure is no easy task. The tough part for you as a pork producer is to think like a crop producer, who values manure by the acre, instead of by the gallon or ton. Then you can...
