Summary:

This paper discusses the impacts of implementing graded chicory root powder into a pig diet and how it effects fecal odour, productive growth, and nutrient digestibility. Six diets of soybeans and corn were given one of six doses of chicory root powder ranging from 0-1%. The root powder at 0.2% was found to reduce H2S in the fecal matter by 40%, while higher levels of the root powder had no effect on fecel matter content. The implementation of the root powder resulted in imporved average daily gain but had a negitive effect on digestibility. The chicory root had improved efficiency of P retention. The use of chicory root in a diet at levels of 0.2% may be beneficial for reducing  fecal excretion of volatile sulfides and improve efficiency of dietary calcium and phosphorus utilization without adversely affecting growth performance and efficiency of whole body nitrogen utilization in weanling pigs fed corn and soybean meal-based diets. However levels higher than 0.2% can have negative impacts on growth performance and efficiency of dietary nutrient utilization without decreasing fecal excretion of volatile sulfides in weanling pigs.
