Abstract

Three mature Thoroughbred geldings were used in duplicated trials conducted before and after cecal fistulation to determine the effects of the fistulation on nutrient digestion and indicator (Cr₂O₃ and polyethylene) retention time. There were significant increases (P<.01) in crude fiber and ether extract digestion following fistulation, while dry matter, gross energy, and crude protein digestibilities were not changed significantly. Retention times of Cr₂O₃ and polyethylene were increased significantly (P<-01 and P<.05, respectively) following fistulation. There were no significant differences among the three methods of determining digestibility. Copyright © 1973. American Society of Animal Science .
