Economic Evaluation of Nutritional Strategies that Affect Manure Volume, Nutrient Content, and Odor Emissions

چکیده
The ability to manage modern pork production systems for minimal environmental pollution has improved dramatically during the past decade, but continues to be one of the most significant challenges facing the pork industry around the world. Nutrition plays a significant role in environmental sustainability of pork production, but the development and implementation of “eco-nutrition” swine feedings programs is in its infancy.

Nutritional and Feeding Strategies to Minimize Nutrient Losses in Livestock Manure
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 cause...
متن کاملIndices of gastrointestinal fermentation and manure emissions of growing-finishing pigs as influenced through singular or combined consumption of Lactobacillus plantarum and inulin.
Conventional dietary strategies to reduce pig manure odor may either be costly, or impede nutrient digestibility. Additionally, the response of manure odor to such measures may be variable, indicating a complex relationship between environmental pollutant and diet. We hypothesized that dietary Lactobacillus plantarum (LP), with or without the inclusion of a purified oligofructose (inulin), may ...
متن کاملCattle feedlot soil moisture and manure content: I. Impacts on greenhouse gases, odor compounds, nitrogen losses, and dust.
Beef cattle feedlots face serious environmental challenges associated with manure management, including greenhouse gas, odor, NH3, and dust emissions. Conditions affecting emissions are poorly characterized, but likely relate to the variability of feedlot surface moisture and manure contents, which affect microbial processes. Odor compounds, greenhouse gases, nitrogen losses, and dust potential...
متن کاملComparison of a wheat-based diet supplemented with purified {beta}-glucans, with an oat-based diet on nutrient digestibility, nitrogen utilization, distal gastrointestinal tract composition, and manure odor and ammonia emissions from finishing pigs.
It was hypothesized that supplementation of an oat-extracted mixed-linkage (1 → 3), (1 → 4)-β-d-glucan (β-glucans) to a wheat-based diet may beneficially mitigate manure odor and ammonia emissions associated with intensive pig production, without depressing nutrient digestibility as has been observed with oat-based diets. An experiment was conducted to investigate the effect of dietary β-glucan...
متن کاملEmission of volatile organic compounds after land application of cattle manure.
Beef cattle manure can serve as a valuable source of nutrients for crop production. However, emissions of volatile organic compounds (VOCs) after land application may pose an odor nuisance to downwind populations. This study was conducted to evaluate the effects of land application method, diet, soil moisture content, and time since manure application on VOC emissions. Manure was collected from...
