Description
Summary:•The effect of Licuri cake (LC) inclusion on gazing lambs diets had been investigated.•LC inclusion increased the daily growth rate and improved the feed conversion ratio.•LC inclusion had no effect on total intake, carcass traits and meat quality.•LC inclusion reduced the NDF digestibility of the diet.•The recommended level of LC for inclusion in lamb's diet is 174 g/kg DM concentrate. This study evaluated the effect of Licuri cake (LC) supplementation replacing soybean meal in concentrate on performance, digestibility, ingestive behavior, carcass traits and meat quality of grazing lambs. Thirty-two uncastrated Santa Inês lambs with a mean body weight (BW) of 24.7 ± 0.9 kg were distributed into 4 treatment diets in a randomized design. Lambs were fed Aruana grass (Panicum maximum cv. Aruana) as roughage and supplemented with a concentrate composed of ground corn, soybean meal and mineral premix. Licuri (Syagrus coronata) cake was added to concentrate at 0 (control), 87.0 (LOW), 174 (MED), and 260 (HIGH) g/kg of dietary DM. Lambs supplemented with LC did not affect DM Panicum maximum intake (P >0.05). However, there was a linear increase (P 0.05) by LC inclusion. However, the digestibility of NFC and NDF (P < 0.05) decreased with the inclusion of LC. Licuri cake inclusion promoted a linear reduction in the time spent feeding and a linear increase in the time spent ruminating, DM, CP and NDF feeding efficiency and NDF rumination. However, DM and CP rumination efficiency presented a linear reduction (P
