Comportamento de ordenha: um estudo de caso em uma propriedade de bovinos de leite no município de Morro Redondo - RS

Abstract

Animal behavior can be observed with the wayhe communicates with humans and the environment. That is, cow-milker interaction may be key to greater productivity and higher profitability in the property of milk. The objective of this study was to report the behavior of dairy cows in the milking shed by comparing two milkers. Behavioral observations were conducted during two consecutive days in three repetitions with an interval of 12 days per replicate of 14 animals of the Jersey breed of a property in Morro Redondo-RS. Through visual observations recorded the behavior of cows by the following variables: defecation, urination, reactivity (movement of the hind limbs). Cases have also been productive responses (milk control). There is very little difference between the two milkers in which the milker had a 51.5% reactivity of the members and the milker 2 with 48.5% of the reactivity. Moreover, there was difference infrequency of defecation and urination among milkers (64.9%). These results indicate that under the conditions of experiment, no stress on the milked animals in milk production in milkers changes.
