Zusammenfassung: | The search for improving the quality of life has been studied through the use of management and facilities that can improve the welfare of farm animals. The objective of this work was to evaluate the influence of different housing systems during the gestation and maternity phases on the behavior and performance of gilts. The animals were distributed in a completely randomized design, with two treatments and four replications, with the gilt being considered the experimental unit. The treatments were: Group 1 - Caged confinement system; Group 2 - Picket and stall breeding system. Data on behavior and reproductive performance of gilts and productive performance of piglets were collected. The gilts in the gestation phase housed in the confinement cages, remained mostly inactive at the three collection times (8:00 – 10:00, 12:00 – 14:00 and 16:00 – 18:00) and shorter alert time between 8:00 – 10:00 and 12:00 – 14:00, compared to gilts reared in paddocks. Animals housed in paddocks remained on alert 87.3% above the observation time compared to females housed in individual cages. Females raised in paddocks had a higher (P < 0.05) number of piglets born alive. All indexes evaluated in piglets did not show differences (P > 0.05) between housing systems. The paddock system during pregnancy provided an improvement in the welfare of the gilts, but it was not enough to improve the reproductive and piglet performance in the maternity.
La búsqueda de mejorar la calidad de vida se ha estudiado mediante el uso de la gestión y las instalaciones que pueden mejorar el bienestar de los animales de granja. El objetivo de este trabajo fue evaluar la influencia de los diferentes sistemas de producción durante las fases de gestación y maternidad en el comportamiento y el rendimiento de las primerizas. Los animales se distribuyeron en un diseño completamente al azar, con dos tratamientos y cuatro repeticiones, considerándose las primerizas como la unidad experimental. Los tratamientos fueron: Grupo 1 – Sistema de confinamiento enjaulado; Grupo 2 – Sistema de cría de piquetes y corrales. Se recopilaron datos sobre el comportamiento y el rendimiento reproductivo de las primerizas y el rendimiento productivo de los lechones. Las primerizas en la fase de gestación alojadas en las jaulas de confinamiento, permanecieron mayormente inactivas en los tres horarios de recolección (08:00 – 10:00, 12:00 – 14:00 y 16:00 – 18:00) menor tiempo de alerta entre las 08:00 - 10:00 y las 12:00 - 14:00 |
