Duration of light for various ages of swine is examined. Barn design in relation to lighting for swine is also addressed.

Use of horizontal and angled perches by broiler chickens

Posted in: Production by admin on | No Comments

Since roosting increases the survival of wild relatives of domestic birds, it was expected that chickens would choose to roost on perches, and would prefer upward angled perches over horizontal because angles perches have the characteristics and accessibility of those found in nature. Perches were provided to 16 pens of male broiler birds in one of four ways: 0A

Odor and Gas Emissions from Animal Manure Storage and Buildiings

Posted in: Environment by admin on | No Comments

Odour and hydrogen sulfide samples were collected from 19 animal storage sites and 26 livestock and poultry buildings in Minnesota throughout 1998. Samples were collected at each one of the locations in spring summer and fall, with the samples be taken from the surface of the manure storage facility and outside the fans on the buildings. These samples were not collected at the property as per Minnesota regulation. H2S and odour building concentration and emission levels varied 22 – 1156 ppb repectively, while odour emission rates ranged from 24 -1515 o.u.. While manure storage concentration and emsission levels ranged from 9 – 1003 ppn for H2S and 39 – 217.2 o.u. for odour. Both odour and H2S levels were found to vary throughout the study, rates were dependant on surface moisture, temperature, wind speed and other factors. H2s and odour concentration levels were found to be more constant over the summer and fall period than other livestock, however these levels were also reported one magnitude higher than dairy levels. The building odour levels show higher values earlier in the year as they did for manure storage units but the magnitude is considerably lower. H2S levels are also lower in magnitude than for pig manure storage units, but do show a similar trend of higher values in the fall compared to those recorded in the spring and summer.

Illinois Extension's Certified Livestock Manager Training Program for Livestock Producers

Posted in: Environment by admin on | No Comments

In May 1997 the Illinois Livestock Management Facilities act became effective. The act focused on four main areas: facility design standards of lagoon storage, setback distances, facility operator education and waste management plans. Illinois extension under contract to Illinois Department of Agriculture developed the Certified Livestock Manager (CLM) training prgram to accomplish producer education set out under the act. The CLM program is mandatory for operations exceeding 300 animal units, and the workshops provide information regarding environmental stewardship, manure management systems, worker health and safety, manure nutrient management programs odour control and Illinois livestock waste regulations.

Correlating Microbes to Major Odorous Compounds in Swine Manure

Posted in: Environment by admin on | No Comments

Malodor generation from swine manure is complicated by the involvement of many bacterial species that produce an extneive array of volatile organic compounds (VOC’s) A lack of understanding of the basic manure microbiology further complicates the problem. This review covers pertenint detailed information about indigenous bacteria generea in swine manure and their poentail for producing odourous volatile compounds. It addresses not only the odorous compounds in swine manure but also the relations between bacterial species and related compounds. It apperas the volatile fatty acids may be the major odorous compounds in swine manure, and two bacteria genera. More research is needed to identify the bacterial species within these two genera to better understand the kinetics of melecular production by the bacteria.

Alternatives to Minimize the Environmental Impact of Large Swine Production Units

As the size of hog operations increase so do the potemtial for complaints of odours, water contamination vehicle traffic and noise. Water contamination complaints have been related to spills, purposeful discharges and structural failure; while odour complaints stem from buildings, manure storage facilities and application. Technologies exist to minimize or eliminate the impact of hog operations on the environment. Producers, elected officials and the public will need to identify concerns and evaluate alternatives to prevent or minimize the impact of intensive hog operations on water quality and the impact odours have on the surrounding area.

New Computer Program Helps Farmers Manage Manure

Posted in: Environment by admin on | No Comments

A new computerized decision-making system for manure management on the farm, developed by University of Guelph researchers, is designed to save money and protect the environment. MCLONE4 is a software package for farmers and consultants, that evaluates cost, labour, odour , nutrients and environment to rate agricultural manure systems. It calculates environmental risks, and makes manure application recommendations and calculations designed for Ontario farms. The program includes extensive on-line help and advice on how to use the program and interpret results. MCLONE4is unique in dealing with more than just manure nutrient management as it covers economics and environmental risk. a
