Tunnel ventilation of swine buildings conveys odorous dust and gases out of the production buildings. Measurement of dust and odor levels and other environmental parameters is necessary for characterizing emissions and evaluating control options. Dur

Intensive swine production generates odorous emissions which flow from the buildings housing the animals. High ventilation rates bring in fresh air, remove heat and moisture and enhance pork productivity. Numerous compounds contribute to the uniquely

Swine producers are faced with a myriad of challenges, especially economic and environmental pressures. In response to a request from the New York State Energy Research and Development Authority (NYSERDA) and the New York Department of Agriculture an

Four sets of total dust and odor measurements obtained during evaluation of an indoor ozonationsystem in a swine finishing building were analyzed. Odors were measured as odor intensity (OI)by a trained panel of humans at the Duke University Taste and

Although windbreak walls have traditionally been applied to reduce ground-level wind speeds and enhance snow deposition, windbreak walls have also recently been placed downwind of animal buildings in efforts to control emissions of dust and odors. In

Three pilot-scale biofilters and necessary peripheral equipment were built to clean odorous air from the pit of a swine gestation building at North Carolina State University. A computer measured temperatures, flow rates, and pressure drops. It also c

A 2.5 m (8.2 ft) diameter paddle fan was developed for cooling floor-raised poultry. An experimental prototype with plywood blades was used to determine effects of blade pitch angle and rotational speed on fan power and air velocities near the floor.

Broiler leg abnormalities cause significant economic losses through decreased body weight gains and increased mortalities. The mechanical properties of poultry cancellous bone could be contributory factors in lameness caused by these abnormalities. F

Fans are essential for effective air mixing and ventilation in poultry housing. Although performance data useful in selecting or comparing fans can be measured by qualified testing services, onsite measurements of fan speed and power use are also use

Tests were conducted to determine effects of air temperature and humidity on misting efficiency b, defined as the fraction of the misting water flow rate which evaporates, for misting systems producing droplet mean volume diameters of approximately 6
