The dry matter digestibility was significantly higher (p<0.05) in T1 (84.30 ± 0.97) and T4 (84.80 ± 0.41). Gas production were significantly higher in T2 (16.82 ± 0.88 ml/g DM) followed by T3 (10.76 ± 0.64) was observed. The overall DM digestibility of all the diets was more than 75%, which showed overall higher digestibility of all nutrients in the prepared therapeutic diets.EnglishVeterinary ScienceArticle
