Abstract
This experiment was conducted to assess the effect of Chaya (Cnidoscolus aconitifolius) leaf pellet (CHYP) on rumen fermentation, nutrients digestibility and microbial protein synthesis in growing crossbred bulls. Four animals, with an average liveweight of 160 ± 10 kg were randomly arranged in a 4 × 4 Latin square design. There were four treatments: 0, 4, 6 and 8% CHYP supplementation of DMI. The study findings showed that increasing supplementation level of CHYP linearly enhanced (p < 0.05) DM, OM, and CP digestibilities. Rumen characteristics, namely NH3–N concentration and bacterial population were increased (p < 0.05) while, protozoal and fungal population remained unchanged, as level of CHYP supplementation increased. Total rumen volatile fatty acids (VFA) and propionic acid (C3) were enhanced (p < 0.05). Furthermore, N utilisation especially N absorption, N retention and efficiency of microbial nitrogen synthesis (EMNS) were significantly improved by increasing level of CHYP supplementation. Hence, CHYP supplementation is highly promising for ruminant feeding.Keywords
