The influence of arborization with algarroba (Prosopis juliflora SW) on behavior and dairy production of grazing cows was evaluated. The trial was made in the rainy season, and six enclosures per arborization treatment were used (low arborization, with 1-7 trees/ha; mid-arborization, with 12-16 trees/ha; and high arborization, with 20-27 trees/ha). Activities were observed every ten minutes during the mornings and afternoons. The number of animals, and each animal´s activity time was recorded. The dairy production data were collected and compared through a randomized design with six repetitions (ANOVA). Significant differences were observed (P < 0.05) to more arborization in grazing (155-173 min), and the monthly values observed were similar. In fields with low arborization, the cows ate less grass, whereas fields with mid and high arborization, the cows grazed longer, and produced more milk (11.2 and 12.59 kg/c/day).
