Pigs Consume more Water When Stressed
Two novel technologies consisting of an individual water consumption system (IWCS) and infrared thermography system (ITHS) were installed in a finishing room. The individual water consumption system (installed in each pen) was composed of a nipple drinker attached to a...
Mitigating Deterioration of Swine Facilities
On average, Canadian swine buildings are 20 – 30 years old; over the next few years, these buildings need renovations or may be replaced with new construction. This project set out to identify potential solutions applicable to Canadian conditions to mitigate the...
Evaluation of a Prototype Air-Filtered Transport Trailer
In response to the need by the industry for a livestock vehicle that addresses increased animal welfare and biosecurity during transport, a prototype air-filtered trailer was developed. Design parameters were gathered from a stakeholders’ survey and initial design configuration options were narrowed down using computer simulation. The...
Development of a Commercial Scale Air Treatment System
An air cleaning technology based on biotrickling filtration developed in previous phases of the project was scaled up and tested at the PSC swine grower-finisher facility. Results showed that the air treatment units were effective in reducing the levels of ammonia, dust, and odour...
Investigating Intervention Measures to Reduce On‐Farm Use of Antibiotics
Prairie Swine Centre has received funding for a research project with the overall goal of determining whether the pattern of antibiotics usage in farms is correlated with the prevalence of specific pig pathogens as well as antimicrobial resistance. In this...
Reducing Water Consumption in Swine Barns: Alternatives for Animal Drinking and Barn Cleaning
Evaluation of selected water conservation measures involving drinkers and different cleaning procedures revealed that 60% reduction in water wastage was achieved with a drinking trough (with side panel and constant water level) to nipple drinkers. The use of conventional nozzle...
Can Trailer Design Effectively Reduce Disease Transmission?
In response to an industry need for a livestock vehicle that addresses both increased animal welfare and biosecurity during transport, a prototype air-filtered trailer was designed and assembled. The project set out to select the best possible option for a...
Engineering Controls Reduce Hydrogen Sulphide Exposure in Swine Barns
Three engineering control measures were developed and tested for effectiveness in protecting swine barn workers from exposure to hydrogen sulfide (H2S) gas during manure handling events. A remote manure pit plug pulling system allowed the worker to pull the manure pit plug from outside the...
Field Testing of an Air Filtration System for Transport
The spread of airborne transmissible disease such as PRRS continues to be a serious threat to the Canadian swine industry as this disease causes significant economic losses to infected herds. Th is project aimed to develop an additional line of defense against infection...
Can Group-Housed Sows Raised at Lower Temperatures?
In this project, an operant mechanism that will allow sows housed in a group system to control their own environmental temperature was developed. Th e mechanism was configured with a manual control switch that the sows can access and operate, which in turn...
Nanoparticles for Controlling Disease – Causing Microorganisms in Pig Barns
Laboratory-scale tests were conducted to evaluate the effectiveness of various types of commercially-available nanoparticles on the levels of microorganisms commonly encountered in swine barns. Results indicate Zinc oxide (ZnO) nanoparticles had the highest antimicrobial efficacy among all the nanoparticles tested. Further experiments carried out...
Geothermal Systems for Heating & Cooling in Swine Barns
This study assessed the applicability of a geothermal system in swine production facilities. In-barn evaluation of the impact of the geothermal system on energy use, thermal environment, greenhouse gas emissions, and animal performance was conducted by comparing a swine grow-finish room with geothermal system...
