Comprehensive control of odors, hydrogen sulfide (H2S), ammonia (NH3), and greenhouse gas (GHG) emissions associated with swine production is a critical need. The objective of this paper is to review the use of soybean peroxidase (SBP) and peroxides as a manure additive to mitigate emissions of odorous volatile organic compounds (VOC), NH3, H2S, and GHGs. Soybean peroxidase plus peroxide (SBPP)...

Both organic and conventional farming processes require energy input in the form of diesel fuel for farming equipment, animal feed, and fertilizer compounds. The most significant difference between the two methods is the use in conventional farming of mineral fertilizers and pesticides that are minimally employed in organic management. It is argued that organic farming is more environmentally f...

A pot experiment was conducted during Kharif season, 2005 to ascertain the response of different organic sources viz., wheat straw, farm yard manure (FYM), vermicompost and poultry manure to rice (Oryza sativa) and also to monitor the effect of manuring on soil carbon pools. Application of poultry manure and vermicompost alongwith chemical fertilizers for supply of nitrogen, phosphorus and pota...

Mineral fertilizers are highly impactful in the agricultural sector, and animal manure can be an alternative to mitigate its impacts. The goal of this research was estimate potential environmental impacts on production soybean, maize, wheat at Lagoa do Sino Farm School from Federal University Sao Carlos, contemplating 2016/2017 cropping season testing replacement 100%, 50%, 30% chemical fertili...

Despite the fact that erosion undermines productivity in the Ethiopian highlands, adoption of fertility enhancing techniques remained very minimal. The objectives of this study is to examine factors affecting adoption of fertilize and manure use and their interrelationships using plot and household level data collected from 211 farm households. A two-stage probit model results revealed a negati...

Producers, researchers, vendors, regulators, and policy-makers are evaluating alternative manure management systems. Motivations include reduction of the level and risk of emissions of potential pollutants to the environment (nutrients, odor, particulates and precursors, gases, and pathogens) as well as the capture of potentially valuable constituents of manure (nutrients, energy, and water). U...

More recently, areas have emerged where swine production is concentrated and where it is no longer possible to simply handle manure as a raw crop fertiliser. Some of the factors responsible for that concentration include a decrease in the number of farms, increasing average farm size, access to feed, labour, packing plants, etc. Consequently, it is crucial to develop new production practices or...

background: most fleas infest their host temporarily then pass to another of the same kind, while others move from one to a different host species. although the comprehensive list of fleas reported from iran, but there still exists considerable gap in our knowledge of zoonotic aspect of flea infestation. the present study was undertaken to determine correlation between domestic animals and man ...

A survey of 715 Holstein dairy farms in Pennsylvania was used to construct demographics for the average Holstein dairy farm. The average Holstein dairy farm was composed of 69 lactating cows; 11 nonlactating, pregnant cows; 44 heifers; and 18 calves. Milk production averaged 27.3 kg (60.0 lb). Crop area averaged 73.6 ha. Milk production, crop area and type, average county yields, and herd anima...
