In recent years, irrigating agricultural land with wastewater has become a major wastewater management practice. Irrigation has replaced much of the discharge to streams and conventional primary and secondary waste treatment for food processing wastewater (4, 11, 12, 13). Irrigating agricultural land for treatment and disposal of the food processing wastewater is a good practice if the wastewat...

Waste silkworm pupae (SWP) generate vast resources of nutrients for livestock and poultry. In the present investigation, three days old chicks of RIR strain were allocated to five dietary treatments of silk worm pupae meal. The energy budget was prepared from calculated proximate analysis and growth performance of broiler chicks fed with different percentages of silk worm pupae. The result show...

The rendering industry collects and safely processes approximately 25 million t of animal byproducts each year in the United States. Rendering plants process a variety of raw materials from food animal production, principally offal from slaughterhouses, but include whole animals that die on farms or in transit and other materials such as bone, feathers, and blood. By recycling these byproducts ...

The critical assessment of bovine adenoviruses (BAdV) as indicators of environmental fecal contamination requires improved knowledge of their prevalence, shedding dynamics, and genetic diversity. We examined DNA extracted from bovine and other animal waste samples collected in Wisconsin for atadenoviruses and mastadenoviruses using novel, broad-spectrum PCR primer sets. BAdV were detected in 13...

The Agricultural Policy/Environmental eXtender (APEX) model was developed by the Blackland Research and Extension Center in Temple, Texas. APEX is a flexible and dynamic tool that is capable of simulating a wide array of management practices, cropping systems, and other land uses across a broad range of agricultural landscapes, including whole farms and small watersheds. The model can be config...

Ammonia emissions are associated with many agricultural operations including animal and poultry operations, waste and wastewater treatment operations, and fertilizer and manure land applications. The fate of ammonia released to atmosphere is affected by interaction with other gases, aerosols, and fine particles. These interactions affect the gas-to-particle conversion. This process alters ammon...
