Odor and Gas Reduction from Sprinkling Soybean Oil ina Pig Nursery

Posted in: Environment by admin on January 1, 1998 | No Comments

Daily sprinkling of small amounts fo soybean oil inside a pig nursery facility reduced odour, H2S and total dust levels of the air inside the barn and in the emission or exhaust ventilation air. Oil sprinkling, as outlined in the MWPS AED-42 publication (40 ml/square meter for the first 2 days, 20 mlk/ square meter for days 3 and 4 and 5 ml/square meter for the remaining time the pigs were in the room. Once every 2 weeks a surge amount of 20 ml/square meter would be added) ,was not effective in reducing ammonia concentrations or respirable dust levels inside the treatment barn when compared to a similar control barn.

World Hog Production: Constrained by Environmental Concerns?

Posted in: Environment by admin on | No Comments

International trade in pork has risen significantly in recent years. Exports of the major pork exporting countries grew at an annual rate of 4 percent during 1989-97 as a result of bilateral and multilateral trade agreements, income growth, and technological innovations in transport and shelf-life extension. There is little doubt that as incomes continue to grow, markets continue to liberalize, and science finds new ways to extend the shelf life of fresh meat over longer periods, international trade in pork will increase further.

Barn management and control of odours

Building odour emissions constitute an important contributor to the level of nuisance caused by a pig farm. Those emissions are less intense than what is produced by manure spreading, but their frequency and duration are much higher. The nature and concentration of more that 160 compounds affect odour characteristics of an air sample collected in a swine building. Considering this complex mix of substances, the human nose is still the best instrument to characterize odours. The forced choice dynamic olfactometry method is the most accepted technique used to measure odour concentration and intensity. It requires a meticulous selection of panel members, expensive equipment and an experienced panel leader. Different techniques have been discussed to reduce odour emissions from swine buildings. Even if a lot of research has been done, many questions stay unanswered. For example, more information is required on performance and impact on odour before new building designs, feed and slurry additives and biofilters can be recommended and applied on a large-scale basis. However, if the barn is kept very clean, the manure is removed as often as possible, an efficient dust control technique is implemented and multiphase feeding programs are used (to reduce nitrogen excretions), odour emissions from the building are likely to be maintained at an acceptable level for the average farm community.
