Abstract

TOFFOLI, G. D et al. Comportamiento ingestivo de agua en vacas lecheras (Datos preliminares). FAVE. Secc. Cienc. agrar. [online]. 2019, vol.18, n.1, pp.67-73. ISSN 1666-7719.

During the summer of 2018, a preliminary test was carried out to determine the drinking behavior of dairy cows in the INTA Rafaela robotic dairy. The temperature and humidity index was estimated to determine the hours of discomfort. Observations of ingestive behavior of water were made during 24 hours. The behavior data were analyzed by ANOVA adjusted to a design model of divided plots with repeated measurements over time and contingency tables were also prepared. A significant effect of drinking behavior was found with the time of day (p = 0.0181). The schedule of greatest water consumption is the morning from 06:30 am to 10:30 am and then a night peak. No correlation was observed between the temperature and humidity index (ITH) and drinking behavior.
