Nutritional and Feeding Strategies to Minimize Nutrient Losses in Livestock Manure
نویسنده
چکیده
The livestock industry has undergone substantial changes in the past few decades. The poultry, swine, and dairy industries in particular have become increasingly concentrated. This has resulted in fewer, but larger, livestock operations throughout the country. As a result, there has been a growing concern about odor emissions from livestock operations and potential decreased water quality caused by nutrient runoff from livestock manure. One of the key components to lowering air and water pollution from manure is the animal diet.

Sustainable nutrient management for pig and cattle manure applied to annual and forage cropping
Introduction Application of livestock manure provides nutrients for crop production and can also improve soil quality. However, the availability of nutrients in manure is difficult to predict. Therefore, livestock manure is frequently under or over-applied with respect to crop nitrogen and phosphorus requirements. In cases where the availability of nutrients is less than expected, application r...

Intensification increases the environmental impact of livestock production systems. Efforts to recycle nutrients in livestock manure for crop production will effectively reduce several pollution problems, although general solutions are difficult to devise in view of the diversity in production systems, management strategies and legislation between countries and regions. This paper argues that a...

During the twentieth century, agricultural production strived to achieve increased food production in order to satisfy both local and export demands. In many cases, this led to increased farm sizes and an operational separation of crop and livestock production. Society fears that the trend of increasing centralization and industrialization of agriculture, specifically animal agriculture, has re...

As a part of the USEPA's concentrated animal feeding operation (CAFO) final rule, all CAFOs are required to develop and implement a nutrient management plan (NMP). The USEPA's emphasis on better management of nutrients appropriately targets a critical environmental issue associated with animal production. The concentration of animals in livestock feeding operations, often separate from feed gra...

Land applications of manure from confined animal systems and direct deposit by grazing animals are both major sources of nutrients in streams. The objectives of this study were to determine the effects of P-based manure applications on total suspended solids (TSS) and nutrient losses from dairy manures and poultry litter surface applied to pasturelands and to compare the nutrient losses transpo...
