Enriquecimento ambiental para o bem-estar de suínos durante o transporte

Abstract

This research was conducted to evaluate the effect of during the breeding period, to the same environmental enrichment provided during the transport of pigs at different stages of the production cycle, considering the enrichment of the creation of a family environment (with experiences previously experienced). Two experiments were carried out, the first one during the transport of pigs from the maternity to the nursery (n= 250) and the second one during the transport of animals from the finishing unit to the slaughterhouse (n=120). The animals were distributed in a completely randomized design, in five treatments: T1 - control treatment without environmental enrichment; T2 - enrichment objects in the truck; T3 - familiar environment using lavender aroma; T4 - familiar environment using music; and T5 - familiar environment using truck noises. The evaluated parameters were: behavior of the animals during transportation, respiratory rate and skin surface temperature, and skin lesion score (before and after transportation). The averages obtained were compared by the Tukey test at 5% significance. The behavior of the animals during the breathing period, respiratory rate (RR), superficial temperature (ST) of the skin and scabs of skin cells (before and after transportation) were evaluated. Advertising by fatigue event due to lower frequency of agonistic activity during the maternity period for a nursery and minor after transportation . Piglets from the larger RR control movement before transport. Pigs set at the rhythms of exposure during a last week of termination are longer discontinuity during transport at birth . Pigs of virus controlled and with a use of aromatics of shorter duration TS of the skin upon arrival at the slaughterhouse. Differences in skin lesion scores were not found . The creation of a family environment for pigs through the use of music presents itself as promising in improving the welfare of animals during transportation.
