STUDY ON BEHAVIOR OF DAIRY COWS KEPT UNBOUND IN CLOSED SHELTER WITH REST BERTHS FROM BUASVM TIMISOARA DIDACTIC STATION PUBLISHED

Nicolae Vuia, Radu Palicica
In order to increase the productivity of dairy farms is required that the old technology of maintaining the animals in the barn stalls to be replaced by a new technology that allows increasing the number of head of livestock per unit of built area and housing costs to be as low and productivity to be at a high level. Observation was conducted in Didactic Station USAMVB Timisoara on 22 lactating cows of the breeds Friză, Bălţată românească and half breeds of Friză and Bălţată românească. The purpose of this paper is to analyze the behavior of dairy cows during the three segments of the day (morning, afternoon and night), following the timing of rest period, movement and feeding, the way how unbound maintenance technology in closed shelters with individual rest bunks meet the animal requirements and its implications on livestock production and management of its opportunities to obtain higher productions. During the experimental cows were in lactation I-IV. Cows were kept in the shelter closed unbound, each cow having reserved a rest bunk. Cow ration consisted of: hay, corn, silage, fodder beet, concentrates. Observation on the behavior of cows lasted 7 consecutive days and was conducted in March. For an easy identification, each animal was marked on the croup with paint receiving a serial number. Was recorded throughout the experimental period at every 15 minutes how each animal is using time. Based on these observations was calculated the average time of sleeping accommodation usage, the use of the alley, and the time consumption of food within 24 hours. ListenRead phonetically Compared to individual differentiation advantage of feeding and caring of the animals kept bound, free stalling gives them the chance to move freely within the shelter, or between shelter and paddock ,which has positive consequences on the fertility of cows, reproductive youth development and even on milk production. However, animals maintenance in groups allow greater degree of mechanization of works and leads to a significant reduction in labor costs related to bound stalling, but requiring uniformity in age or physiological status of animals.
