Effect of Ractopamine in Finishing Diets: Economics
The beta-adrenergic agonist known to stimulate muscle growth and inhibit fat deposition known as ractopamine is the active ingredient in Paylean®, which was recently registered in Canada. The relative economics of this product will impact the final decision to use this feed additive. Costs include...
Effect of Ractopamine in Finishing Diets: Meat Quality
Ractopamine is the active ingredient in Paylean® and is known to stimulate muscle growth and inhibit lipid deposition. The impact on the eating quality of pork are unclear and few studies include taste evaluation. It is crucial to have the consumers acceptance of the pork...
Effect of Ractopamine in Finishing Diets: Performance and Carcass Composition
The active ingredient of Paylean® is ractopamine known to stimulate muscle growth and inhibit lipid deposition. It has recently been registered in Canada and is used to increase the profitability of pork production. Paylean was evaluated to see its effects on carcass characteristics, performance, carcass...
Response of Growing Pigs to Graded Levels of Flaxseed
As a way to diversify rations and reduce cost or to alter the final pork product, alternative ingredients for pig diets are often investigated. Flaxseed is of interest as the amount of acreage for flax is increasing so the quantity available will rise. A nutrient...
Developing Weaning Pig Programs Based on Age and Weight
Needs for less antibiotic usage, lower costs, improved performance and reduced variability make feeding the newly weaned pig challenging. Diets were monitored on pigs of different weight and age to see what they respond to better in order to reduce body weight variability after the...
Interaction of Net Energy Concentration and Feeding Level in Weaned Pigs
Growth is restricted in weaned pigs due to energy intake possibly because of restrictions in gut capacity. Energy intake and growth should increase when dietary energy concentrations increase, but recent findings do not support this. Weanling pig performance was not improved because feed intake declined...
Increasing Diet Tallow and Dietary Energy on Performance
The most expensive nutrient in pig diets is energy. Previous research has shown that diets with differing energy concentration led to equivalent performance in pigs. Dietary energy was investigated regarding its impact on carcass quality, uniformity of growth and its relationship to pig performance. Grower-finisher...
Effect of Wheat Quality and Xylanase Supplementation on Weaned Pigs
Variation in nutritional quality of feed is common and impacts the pigs performance. Protein and fibre content influence nutritional quality between wheat samples. A fibre degrading enzyme supplement may reduce quality variation of wheat on pig performance. The variation was partially reduced by xylanase supplementation...
Nutritional Value of Corn and Wheat Distillers Grain and Growth Performance
Increasing quantities of distiller's dried grains with solubles (DDGS) are becoming available for livestock rations as the ethanol industry grows. The nutritional value of DDGS is not fully understood for swine. Generally, a higher concentration of nutrients such as protein, vitamins, fat, fibre and minerals...
Xylanase and Phytase Supplementation on Growth Performance of Grower Pigs
If nutrients bound by the arabinoxylan and phytate of wheat millrun could be released through enzyme supplementation, feed costs may decrease or nutrient intake may be enhanced. Larger inclusion rates of wheat millrun into swine diets could also be allowed while maintaining growth performance. Decreasing...
