Inclusion of non-protein nitrogen and lysine in grower pig diets on growth performance
Results from our previous study demonstrated that inclusion of non-protein nitrogen (NPN) in a diet with a high essential amino acid-nitrogen:total nitrogen (E:T) ratio (i.e. limiting in total nitrogen [N]) increased the Lys requirement and maximum N retention in growing...
Inclusion of non-protein nitrogen in grower pig diets on lysine requirement for maximum nitrogen retention
Low protein diets have improved nutrient utilization while maintaining animal performance. However, these diets may be limiting in nitrogen (N) content to meet non-essential amino acid (NEAA) requirements, potentially altering essential amino acid (EAA) utilization and requirements. Inclusion of a...
Non-essential amino acids affect nitrogen retention in pigs
Low-protein diets supplemented with essential amino acids (EAA) can improve growth and performance. However, the dietary amount of non-essential amino acids (NEAA) may be a limiting factor in these diets. This may ultimately affect the efficient utilization of the dietary...
Response of growing pigs to the inclusion of hybrid rye in low or high energy diets
This experiment was designed to determine if increased dietary energy content will compensate for the reduced feed intake previously shown in pigs fed diets with hybrid rye substituting for wheat. We hypothesized that pigs fed 40% hybrid rye would perform...
Effect of feeding time on the proportion of sows farrowing during work hours
It is sometimes necessary to provide assistance to sows and piglets during farrowing in order to improve piglet survival, resulting in increased labour costs. There is evidence in cattle and ewes that feeding at night results in an increase in...
Ileal alkaline phosphatase is upregulated in Salmonella-challenged pigs fed functional amino acids
Functional amino acid (FAA) supplementation improves growth performance and immune status of Salmonella Typhimurium (ST)-challenged pigs, which was further improved by a longer adaptation period. It is expected that the effects are associated with increased activity of intestinal alkaline phosphatase...
Response to functional amino acids in plant-based nursery diets in pigs subsequently challenged with Salmonella
Functional amino acids (FAA) attenuate the effects of Salmonella challenge in pigs. However, this may be affected by protein source (PS). The objective of the present study was to determine the effects of nursery dietary PS and FAA supplementation on...
Can functional amino acids help low birth weight pigs in a Salmonella challenge?
It is not known if supplementation with functional amino acids (FAA) may mitigate the negative effects of intrauterine growth retardation seen in low birth weight (LBW) pigs. The objective was to determine the effects of birth weight category (BWC) and...
Out of feed events and gastric ulcers in finishing pigs fed 40% pea-starch diets
Gastric ulcers in pigs are a concern for the industry. To be able to study gastric ulcer formation, an experimental model is required that will consistently result in gastric ulcers in pigs. The objectives of this pilot study were to...
The use of extrusion to reduce dietary ergot toxicity in growing pigs
Consumption of ergot alkaloids by livestock results in reduced feed intake and growth and a dramatic reduction in the hormone prolactin, which is important for milk production in sows. Previous research at the PSC demonstrated that extreme processing in the...
Managing High Feed Costs
Feed costs always will be the single largest component in costs associated with pork production. Finding ways to effectively reduce feed costs while optimizing pig performance helps producers economic sustainability. This publication focuses on four key areas including: 1) Diet...
Can hybrid rye replace wheat in swine diets?
Modern rye hybrids are less susceptible to ergot contamination than traditional rye, and has greater yield compared with wheat grain, which was a good incentive to evaluate feeding hybrid rye to grow-finish hogs. Rye is known to have greater fibre...
