The objectives of this study were to assess the behavior of goats on pasture under different grazing inTanzania grass cultivated and irrigated pasture, during dry season.This experiment has been carried out atEmbrapa Caprinos in Sobral, Ce, Brazil during dry season. Daily temperature during dry season averaged30oC with minimum and maximum value close to 24oC and 35oC, in this order. Relative humidity averaged53%. Daily pasture was irrigated except paddocks with goats. Nubian goats were tested.Was used a rotationalgrazing system. Pasture was management to get four levels of grazing: intensive (pos grazing residue-PGR30cm and N supplied 600 kg/ha year); moderate (PGR 45cm and N supplied 300 kg/ha year), light (PGR45cm without N supplied) and extensive (PGR 30cm without N supplied. Grazing behavior was assessed bydirect observation. Goat activity in terms of time spent eating, chewing, and resting was monitored every 10min. Activities like to urinate, to defecate, to drink other and salt intake were measured when occurred.Theaverages were compared using Kruskal-Wallis test (p <0.05). The SAS 9.0 software was used to perform thestatistical proceeding.No significant differences to grazing time, ruminantion time and resting time wereobservated among treatments. The animals spent time averaged 29%, 23% and 49% with grazing, chewingand resting in this order. The frequency urinating, defecation and drink water was low to all treatments. Theanimals in moderate intaked more salt than other.Was observed effect of hours on main activies. Grazing wasmore intensive at morning (5-12hrs) and after milking (15-17hrs). A small period was observed at night (20-23hrs).Was observed rumination in all hours, but at dawn (0-5hrs) the animals spent more time withrumination than other activities. Animals spent more time to resting during night. No significant effect oftreatments was observed on grazing, rumination and resting time. In conclusion, animals spent more time withgrazing during morning and afternoon while rumination and resting time was mainly measured during night.These results are a typical behavior of ruminants in pasture.
