The aim of this study was to evaluate the effect of increasing levels of cashew nut shell liquid (CNSL) in ruminant diets on in vitro dry matter digestibility (IVDMD), gas production kinetics, ruminal fermentation parameters, ammoniacal nitrogen concentration (NH3-N), and pH of the artificial rumen contents. The experimental design was completely randomized in a factorial 5 x 4 + 1 design, with five concentrate levels (200, 400, 600, 800, and 1,000 g kg-1 DM) and four CNSL levels (0, 0.3, 0.6, and 1.2 g kg-1 DM), as well as a control diet comprising only whole-plant corn silage, totaling 21 treatments. The inclusion of concentrate linearly increased IVDMD, while CNSL levels showed a quadratic effect, with the maximum estimated at 0.5 g kg-1 of CNSL. The total gas production, the disappearance of the substrate, the fraction of slow degradation (fraction VF2), and the respective degradation rate (fraction µ2) linearly increased with increasing levels of concentrate in the diet. Increasing concentrate levels resulted in a linear increase in the concentration of NH3-N and a reduction in the pH of the rumen liquid. Increasing CNSL levels decreased the concentration of NH3-N and increased the ruminal pH. The inclusion of 0.5 g CNSL kg-1 in the ruminant diets improved IVDMD, without altering the kinetic parameters of ruminal fermentation. The addition of CNSL to ruminant diets reduces ammoniacal nitrogen production and can avoid drastic reductions in ruminal pH, favoring better fermentation in the rumen.

ABSTRACT This study evaluated the in vitro digestibility of nutrients from different diets added with chitosan (Q), technic cashew nut shell liquid (LCC) and the association of Q and LCC. The treatments used consisted of 4 diets (forage: concentrate ratio of 100: 0, 50:50, 40:60 and 20:80) associated with 4 additives (control, chitosan, LCC and the association of Q + LCC), totaling 16 treatments, in a 4x4 factorial randomized block design. The dosages used were: Control (without additives), LCC (600mg/kg DM), Chitosan (900mg/kg DM), and LCCQ (600mg/kg LCC DM + 900mg/kg Chitosan DM). In the laboratory, samples were analyzed for IVDMD, IVNDFD, IVCPD, pH and RAN (ruminal ammonia nitrogen). For pH and RAN analyses, samples were taken at 0, 2, 4, 6 and 8 hours after incubation. The results showed higher digestibility of DM, NDF and CP for diets with chitosan and technic cashew nut shell liquid alone and higher pH and RAN values in the diets containing the two additives. The association of additives brings better results for animal nutrition and increases ruminant productivity.
