Cleaning Ease and Animal Welfare Implications of Trailer Design
The aim of this initial study was to develop an inventory list of trailers commonly used for the transportation of market hogs in Canada. Hog transport companies in Saskatchewan, Manitoba and Ontario were visited in order to document various trailer features specifically those influencing ease of cleaning and animal...

Influence of Sow Lactation Feeding System on Performance
All three feeding systems resulted in similar sow and litter performance, however, both the electronic and modified feeding system resulted in a significant reduction in feed wastage and, therefore, an estimated saving in feed costs of $8.50 per lactation compared to manual feeding. The modified feeding system is a...

Spray Dried Bovine Plasma for DON Contaminated Nursery Diets
The current experiment showed that DON did have a detrimental effect on ADFI and also showed some negative eff ects on ADG. Moreover, SDBP showed a beneficial effect on ADFI when present with DON in the diet but did not have a beneficial effect on ADG. Finally, DON...

Effect of Grinding on the Digestible and Net Energy Content of Field Peas
This project aimed at generating reliable information on the digestible and net energy content (DE and NE) in growing pigs fed with field peas ground at 3 different screen-opening sizes (fine, medium and coarse) to obtain different average particle sizes: 156, 650 and 1035 μm, respectively. The digestibility...

Flaxseed Meal in Swine Rations: Standardized Ileal Amino Acid Digestibility
Flaxseed meal contains 34% CP and also contains appreciable amounts of many of the essential amino acids. The SID coefficients for the essential amino acids range from 67 to 94%, which affeccts the overall protein quality of the product; however, the amounts of SID essential amino acids in...

Net Energy Content of Canola Meal and Full-Fat Canola Seeds in Swine
The project aimed to estimate the net energy (NE) content of canola meal (CM) and full-fat canola seeds (FFCS) in swine and to validate these values, through growth studies using diets containing graded levels of CM or FFCS. No difference in average daily gain and feed conversion ratio...

Digestible and Net Energy Content of Toasted and Non-Toasted Canola Meal
Canola meal (CM) is a valuable source of essential amino acids for pigs, although the digestibility of these nutrients is limited by both composition (high dietary fibre level) and processing (toasting). Its low energy value is probably the most limiting factor for its use in swine nutrition and...

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...
