    Abstract:
    The effects of dietary alkyl polyglycoside [APG, a nonionic surfactant (NIS), derived from a reaction of corn starch glucose and a natural fatty alcohol] inclusion on digestion of nutrients and ruminal fermentation in goats were examined in a 4 × 4 Latin square design using 4 ruminally and duodenally cannulated wethers (mean BW: 19.5 ± 0.8 kg). The animals were assigned to 4 dietary treatments of APG supplementation at 0, 3, 6, and 12 g/kg of DM diets and were designated as control, APG3, APG6, and APG12, respectively. The results showed that dietary APG inclusion tended to increase the intestinal digestibility of OM (linear, P = 0.09) and NDF (linear, P = 0.1), and quadratically increased (P ≤ 0.02) total tract digestibility of OM and NDF, the duodenal microbial N flow, and efficiency of microbial protein synthesis. The true ruminal digestibility and apparent total tract digestibility of N quadratically increased (P < 0.01) with increasing dietary APG. The ruminal pH values were not affected by dietary APG inclusion (P > 0.05), but the concentration of NH(3)-N (P < 0.01) and total VFA (linear and quadratic, P < 0.01) increased in the rumen fluid. Dietary APG inclusion also increased the activities of ruminal carboxymethyl cellulase (quadratic, P < 0.01) and xylanase (linear and quadratic, P < 0.01). It is concluded that APG is a potential feed additive that can be used in ruminant production; 6 g/kg in the total mixed rations for goats is recommended. It is necessary to validate the effectiveness of dietary APG inclusion in ruminant diets with more animals in further studies.
