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 to a conventional production room with...

Assessing Whey to Reduce Feed Cost
Deproteinized whey permeate is a by-product of the cheese-making industry. Depending on the type of cheese being produced it can be categorized as “sweet whey” or “acid whey”, the latter contains about 4.7% organic acids. The objective of this experiment was to determine the response of weanling pigs to...

Effect of Dietary Calcium and Phosphorus in Sows
This study was designed to determine the influence of Ca and P intake by young, gestating sows on the growth and skeletal development of their developing piglets and if smaller birthweight piglets are at greater risk from mineral insufficiency during gestation. A total of 30 sows were randomly assigned...

Can Flaxseed Replace Antibiotics in Starter Diets?
We hypothesized that feeding n-3 FA’s to sows in the form of flaxseed would allow for the removal of Ab’s in starter feeds. Based on the findings from this trial, we can neither accept nor reject this hypothesis, as we found that in our high health herd, Ab’s...

Feeding Value of Cull Lentils
The current study was designed to characterize the nutritive composition, including digestibility and energy concentration, of feed-grade (cull) lentils for growing pigs. We conducted two studies. The first study determined the amount and digestibility of energy and amino acids in two samples of lentils. In the second study...

Stimulating Exploratory Behaviour – Effect on Creep Consumption
This study investigated whether feed consumption before and after weaning can be increased through stimulating exploratory behaviour in piglets, and whether this is best achieved through provision of enrichment (E), or through presentation of creep feed in a large tray feeder (TF) so as to facilitate synchronized feeding among littermates. Enrichment...

Weaning Sows Directly into Group Housing
Social stress from mixing sows has the potential to negatively affect sow production and welfare. Housing sows in stalls from weaning until five weeks after breeding is a common strategy used to prevent aggression and ensure control over individual feeding during breeding, conception and implantation. However, alternative management options are...

Does the Inclusion of Lyso-Lecithin (Lecired) Improve the Growth of Newly Weaned Pigs?
In conclusion, the addition of 10% (of dietary fat) lyso-lecithin to high or low energy diets of weanling pigs had only modest effects on the performance of these piglets, regardless of the inclusion of tallow in the diet. Future experiments need to clarify if fat emulsification is limiting...

Fermented Soybean Meal for Weaned Pigs
Soybean meal contains a variety of anti-nutritional factors which limit its inclusion into the diets of young piglets. It has been shown that fermentation of soybean meal (fSBM) eff ectively removes trypsin inhibitors, oligosaccharides and phytic acid and improves digestibility of nutrients, including amino acids. These improvements however, are not...

Developing Spray-Dried Animal Plasma Programs for DON Contaminated Diets
This study was designed to determine if feeding high quality diets supplemented with spray-dried animal plasma (SDAP) during the early post-weaning period, will provide benefits if deoxynivalenol (DON)contaminated diets are fed in subsequent phases. Two blocks of newly weaned pigs were fed according to a 3-phase feeding program...
