GUEVARA VIERA, Raúl V et al. Effect of Algarroba on Grazing Cow Behavior and Milk Production. II. Rainy Season. Rev. prod. anim. [online]. 2016, vol.28, n.1, pp.10-15. ISSN 2224-7920.

The effect of algarroba (Prosopis juliflora, SW) arborization on grazing cow behavior and milk production was assessed. The trial was made in the rainy season, and six enclosures were used per arborization treatment (low arborization, 1-7 trees/ha; mid arborization, 12-16 trees/ha; high arborization, 20-27 trees/ha). Rational grazing was performed. The grass rested for 21-28 days, and sprinklers were used for irrigation. Each animal´s activity time, and the number of animals, were registered. Milk production values were compared using ANOVA, following a randomized design with six replicas. No significant differences were observed in the morning grazing (118 -203 min),but there were significant differences (P < 0.05) in the afternoon, positively toward more arborization (103 -125 min), whereas in lands with mid and high arborization, cows ruminated longer, with higher water consumption and milk production, and values between11.85 - 13.76 kg/v/day.
