Abstract
Evaluation of Pellet Binders on Pellet Durability Index of a High-Fat Swine Diet
Highlights
Swine diets are pelleted to improve bulk density, transportation characteristics of feeds, reduce ingredient segregation during handling, decrease dust levels, reduce feed intake, increase weight gain, and improve feed utilization.3 in order to maintain this advantage pellets must be of high quality
The objective of this study was to evaluate the addition of different pellet binders on pellet quality of a grower swine diet by measuring pellet durability index (PDI)
Dietary treatments consisted of a corn-soybean meal-based control diet with 20% dried distillers grains with solubles and 4% choice white grease, the control diet with 0.6% lignosulfonate (AMERI-BOND 2X; LignoTech USA Inc.; Rothschild, WI), or the control diet with increasing levels of a pasta by-product
Summary
Swine diets are pelleted to improve bulk density, transportation characteristics of feeds, reduce ingredient segregation during handling, decrease dust levels, reduce feed intake, increase weight gain, and improve feed utilization. in order to maintain this advantage pellets must be of high quality. Swine diets are pelleted to improve bulk density, transportation characteristics of feeds, reduce ingredient segregation during handling, decrease dust levels, reduce feed intake, increase weight gain, and improve feed utilization.. Previous research indicated that nursery pigs fed diets with poor quality pellets reduced feed efficiency to levels similar to those of the mash control diet.. Many factors affect pellet quality, including ingredient particle size, formulation, and processing variables, such as conditioning temperature and duration, screw configuration and speed, and mash moisture. A variety of pellet binders have been tested, with a limited number being widely used within the swine industry. One of the more common pellet binders used in animal feeds is lignosulfonate (AMERI-BOND 2X; LignoTech USA Inc., Rothschild, WI). New by-products from the food industry are becoming available for use as pellet binders. The objective of this study was to determine the effects of lignosulfonate and 3 different concentrations of a pasta by-product on pellet quality by measuring pellet durability index
