World Hog Production: Constrained by Environmental Concerns?
Posted in: Environment by admin on January 1, 1998 | 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.

Evaluation of humidity sensors in a swine barn
Posted in: Prairie Swine Centre by admin on | No Comments
Humidity sensors are affected by the air quality in livestock buildings. New sensor models should be tested under actual barn conditions to assess their long-term integrity. An experimental procedure was developed to meet this requirement. After initial static and dynamic calibrations in a specially designed humidity chamber in the laboratory, the test sensors were installed in a livestock building for one year. Several times during the year, the sensors were temporarily removed from the barn and taken back to the laboratory for calibration against a reference hygrometer ad determination of static and dynamic properties including accuracy, hysteresis, and time response. A bank of 72 TDK humidity sensors with different filters and coatings were evaluated with this procedure in a grower/finisher room. The drift of various static and dynamic sensor characteristics over time, the reliability, and the durability of the sensors were identified and the best sensor treatment was selected. The results confirmed the value and practicality of the test procedure, and led to recommendations for the appropriate length of the in-barn evaluation period, calibration frequency, and required replication.

Energy Usage and Lactating Sow and Piglet Performance in Farrowing Compartments with a Lowered Set Point of the Room Temperature
Posted in: Energy by admin on | No Comments
Most of the energy usage within a sow farm occurs in the farrowing compartment. Can a reduction in temperature setting of 2C in combination with an adequate micro-climate contribute to energy savings and improved lactating sow performance? The study was conducted in four naturally ventilated farrowing compartments using a total of 96 sows. The reduction in room temperature had no effect on lactating sow and piglet performance. Energy savings in the compartments with reduced temperature is addressed.
