LEVA, P. E et al. Evaluación del bienestar en vacas en un sistema de ordeñe automatizado durante la época estival: Estudio de caso. FAVE. Secc. Cienc. agrar. [online]. 2017, vol.16, n.1, pp.131-140. ISSN 1666-7719.

Thirty-seven heifers were housed in a pen with access to a robotic dairy farm. They had shadows in the feeder and resting places. From 18:00 hs to 08:00 hs had access a pasture. Behavior was recorded weekly for 24 hours. Twice a week at 5 times the respiratory rate was observed individual production was recorded daily. Weekly dairy control was performed. Two dates blood collection were performed to evaluate the level of cortisol. The average respiratory rate was 70 rpm. Milk production was 28 l v^-1 d^-1. The present cortisol values between 10 and 48 ng ml^-1. Animals destined to 25, 1 % and 26, 1 % eating and ruminating behaviors and only 0.7% respectively to drink. The results are preliminary; indicate the feasibility of introducing automated systems combined with stress mitigation methods.
