Response of Finishing Pigs to High and Low Crude Protein Diets
Supplementing a low protein diet with the limiting amino acids is often more cost effective than using an additional amount of the particular protein source. Two experiments conducted using grower and finisher pigs confirmed that performance could be maintained when either high or low crude protein diets are...
High-Oil Oat Groats for Weaned Pigs
The interest for weaned pigs of oat groats with high oil content was evaluated. The groats contained 95 g oil, 159 g crude protein and 3.72 Mcal DE/kg DM. Weaned pigs fed for 4 weeks (7 to 22 kg) with diets containing graded levels (0, 15, 30, 45%)...
Reducing Energy Use in Group Housing Systems
In this study, controlled-chamber experiments were carried out to develop an operant mechanism that allowed the sows to demonstrate their preferred environmental temperature and to study the effects of fibre addition on growth performance and physiological response. Results showed that sows fed with high heat-increment diet were able to...
Ensiled High Moisture Barley and Wheat in Nursery Pig Diets
The primary objective of this research was to investigate the nutritional value of high moisture (HM) barley and wheat ensiled with lactic acid bacteria (LAB) with or without the addition of feed enzymes for nursery pigs. Overall, the results showed that HM barley and wheat can be...
Can Nanoparticles Control PEDv?
This project set out to evaluate the efficacy of novel metal nanoparticles (with previously demonstrated antimicrobial properties), either alone or in combination with alternative disinfecting strategies for inactivation of PED. Conducting the work under Biosafety Level 3 containment, experiments that simulated hog production environments showed that copper...
Evaluating Novel Technologies
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 water fl ow meter, and an RFID...
Practical Alternatives for Castration
The Canadian Code of Practice requires that swine producers provide analgesics to piglets at castration to help control post-procedural pain. However, complete information on the different analgesics available to control post-procedural pain, their effectiveness and optimized procedures for delivering pain control have not been identified. This project...
Determining Optimum Space Allowance for Nursery Pigs
Studies were conducted in 2 phases to determine the eff ects of six diff erent space allowances (k= 0.0230, 0.0265, 0.0300, 0.0335, 0.0370, and 0.0390) on nursery pig behavior, growth and welfare from 3 to 8 weeks of age. Phase 1 was a controlled trial conducted at...
Ventilation System Requirements for Converted Gestation Barns
Computer simulation was utilized to assess the performance of different ventilation system configurations needed for a sow gestation barn newly converted to group housing. Various configurations of the ventilation system involving varying capacities and locations of exhaust fans as well as size, design and location of air inlets, were...
