Over one billion tons of agricultural, municipal, and industrial wastes with potential uses in agriculture are generated annually in the United States. Many of these materials are applied to agricultural land because of the benefits they provide. These benefits include: providing a nutrient source for crops; improving soil chemical, physical and biological properties; improving water storage an...

This study evaluates the occurrence of bacteriophages carrying antibiotic resistance genes in animal environments. bla(TEM), bla(CTX-M) (clusters 1 and 9), and mecA were quantified by quantitative PCR in 71 phage DNA samples from pigs, poultry, and cattle fecal wastes. Densities of 3 to 4 log(10) gene copies (GC) of bla(TEM), 2 to 3 log(10) GC of bla(CTX-M), and 1 to 3 log(10) GC of mecA per mi...

The increase of healthcare facilities in Shinyanga municipality has resulted in an increase of healthcare wastes, which poses serious threats to the environment, health workers, and the general public. This research was conducted to investigate management practices of healthcare wastes in Shinyanga municipality with a view of assessing health risks to health workers and the general public. The ...

This paper presents the utilization of the multi-agent platform Geamas through the Biomas application for the collective management of animal wastes. The complexity of the scenarios under study gives rise to many unpredictable behavioral schemas whose analyses necessitate a simulation approach. In the present article we describe the whole set of concepts in use in multi-agent systems modeling a...

Solid and liquid wastes from livestock operations represent important challenges for animal production regarding their impact in the environment and public health. Parasitological tests performed on 80 samples of affluent and effluent waters from three anaerobic biodigestors with flexible structure from swine farms of Caldas - Colombia, showed the presence of Isospora suis (45%), Eimeria suis (...

The stable fly (Stomoxys calcitrans) has historically been a pest of dairy cattle and feedlots due to the availability of decaying plant matter mixed with animal excrements in such production systems. In the last few decades, stable fly outbreaks have also been reported in pasture-raised beef cattle, usually associated with wastes accumulated from animal feeding during winter, the introduction ...

Vegetative Treatment Systems have historically been a practice for the treatment and utilization of open lot livestock wastes. Use of these systems has been rejuvenated in recent years. A “sprinkler” vegetative treatment area (VTA) has been designed and developed as a proof of concept for addressing challenges experienced with small and medium Animal Feeding Operations. The focus of this paper ...

Since a biological filter with nitrifying bacteria was firstly applied to aquatic animal experiments in IML-2 mission, the reactor system has been further studied to combine both nitrifying and denitrifying reactions under aerobic environment allowing an efficient removal of inorganic nitrogen from animal wastes. The isolated denitrifying bacteria had an activity under aerobic condition with ri...

Organic wastes are extensively increasing with increased human populations, intensive agriculture and industrialization. The disposal of wastes has become important for a healthy quality of environment. In this regard recycling of utilizable organic wastes is feasible. The recycling of wastes through vermicomposting reduces problems of disposal of organic wastes. Vermicomposting, a novel techni...

Biodegradation of livestock processing waste is one the more cost-effective, ecologically safe recycling methods thatmay preserve nutritional content and key amino acids useful in animal feed production. Here, we determined thebiodegrading potentials nonconventional feedstuffs using a combination bacteria (Bacillus subtilis) fungi(Fusarium sp.). Five types (feather meal, hair waste, egg membran...
