Resumo
The experiment was conducted to evaluate the feeding behavior of lambs fed with diets containing 0, 12.5 and 25.0% of mulberry hay as a substitute for the concentrate. Twenty four Ile de France lambs, non castrated, with 25 kg of body weight and four months old, confined, in a completely randomized design, were used. The feeding daily time (242.01 minutes), rumination (435.48 minutes) and leisure (762.50 minutes), the numbers of cakes ruminated per day (658.36) and the time spent per cake (40.03 sec) were not affected (P>0.05) by different levels of hay in mulberry concentrate. The dry matter voluntary intake (1.258 kg/day) and neutral detergent fiber intake (0.302 kg/day), as well as the efficiency of dry matter intake and rumination (316.24 and 173.54 g/h, respectively) and efficiency of neutral detergent fiber intake and rumination (75.89 and 41.68 g/h, respectively) were similar in all treatments. The ruminating chew expressed in hour/day (11.29) and the number of chews expressed per cake (72.65) and per day (47.638.06), as well as the number and the feeding time (22.02 meals and 11.23 min/meal), rumination (25.95 ruminations and 17.29 min/rumination) and idle (41.81 idle and 18.30 min/idle time), were also not affected (P>0.05). The inclusion of mulberry hay did not change the rumination expressed in g of DM and NDF/cake (1.91 and 0.46, respectively) and min/kg of DM and NDF (361.51 and 1.505.78, respectively), as well as the total chew expressed in min/kg of DM and NDF (563.70 and 2.347.19, respectively). The use of mulberry hay partially replacing the concentrated, does not change the feeding behavior of feedlot lambs.
