#### *3.1. Productive Performance and Digestibility*

Final body weight (FBW) was not affected by treatments (Table 1). For dry matter intake (DMI), no significant differences were found among the treatments during the experimental period. On the other hand, DWG showed a tendency of linear decrease (*p* = 0.06), and the lambs that were supplemented with HM3 performed lower than the lambs fed with the other diets. However, the feed conversion ratio was not affected by the level of HM added to the diet. On the other hand, the dry matter digestibility (DMD) decreased linearly (*p* = 0.03) as the dose of HM in the diet increased. The lowest digestibility of DM was observed in lambs fed HM3 diet (Table 1).

1 Peptasan® based on *Saccharum officinarum, Balanites roxburghi and, Acacia concinna*. CON—basal diet without polyherbal mixture (HM); HM1—basal diet + 1 g of HM kg−<sup>1</sup> of DM; HM2—basal diet + 2 g of HM kg−<sup>1</sup> of DM; HM3—basal diet + 3 g of HM kg−<sup>1</sup> of DM; EEM—standard error of the treatment means; a,b—means within a row with different subscripts differ when *p* ≤ 0.05; \*—indicates a tendency.
