ENRIQUECIMENTO AMBIENTAL MUDA COMPORTAMENTO DE BEZERRAS QUE RECEBERAM AFAGO

The objective of this study was to evaluate the behavior of heifers two consecutives hours after brushing in 2 diferent environments, an environmental enriched (EE) and another environment without enrichment (EWE). The heifers were F1 cross from Gir Leiteiro bull and Holstein cows. EE had play objects. The mean time of brushing animals in the enriched environment was 1.93min while animals in the non-enriched environment allowed 2.48min time of brushing, differing from each other (P <0.05). The EE in the first hour was significant for the variables lying down (P = 0.0016), standing (P = 0.019), walking (P = 0.0025) and playing activities (P = 0.0016). For the eating activity, there was an interaction between treatment and day, and the animals without environmental enrichment spent more time eating (P = 0.0071). In the second hour, animals from the enriched environment spent less time lying down than animals without EE (P <0.001). EE has changed the behavior of heifers.
