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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
Mitigating DON Through Optimal Use of Blood Plasma
Previous research showed that nursery pigs fed deoxynivalenol (DON) contaminated diets supplemented with spray-dried porcine plasma (SDPP) had similar growth rate and feed intake as those consuming non-contaminated diets. In this study, two blocks of 100 weanling pigs were used to determine the optimal...
