Animals were randomly allotted into four groups of 8 lambs each viz., T1, T2, T3, and T4 in a completely randomized design and reared for 3 months of weaning age. The four isonitrogenous and isocaloric complete diets varying in non-structural carbohydrate (NSC) levels were prepared and offered to the respective treatment groups ad libitum throughout the study in addition to milk suckling from their dam. The DMI and BCS were lower in T1 and were increased as dietary NSC levels increases. Among the treatment groups, lambs on a higher NSC diet (T4) had significantly (P<0.05) higher faecal scores and a better score was observed for T2. The faecal DM, NDF content was significantly (P<0.05) lower and the NSC content was higher in T4 group. It could be concluded that a higher level of NSC in the diet increased the faecal score, indicates that the disturbance in the rumen fermentation and need dietary intervention to improve faecal consistency when such high NSC feed used for higher weight gain.EnglishVeterinary ScienceArticle
