RESUMO:

The world scenario of pig production has evolved in all its aspects. Market demand for regulations related to animal welfare and improvements in production processes increases significantly each year. It is essential to know the influence of new systems of housing of swine matrices in gestation, on the reproductive performance of these animals and animal welfare, the objective of the present work was to evaluate the effect of the housing systems of matrices regrouped in collective bays and cells individual newly inseminated animals, on zootechnical indexes and parameters of well-being. We evaluated the housing systems: covered and housed in collective stalls after three days (G3); covered and housed in collective pens after 35 days of gestation (G35), remaining in individual cells before this period. For the study, a total of 524 females of the Camborough 25 and TOPIGS TN70 strains were used. The insemination protocol was from 0h-24h-48h. Data collection began in May 2017 and ended in March 2018. Throughout the experiment until delivery, information was collected on: number of doses used, pregnancy rate, calving rate and number of live-born piglets. For the evaluation of female welfare parameters, individual observations were made on adapted indicators of Welfare Quality® related to the gestation phase. In the evaluation of the total number of infants, the mean was 14.6 piglets and there was no significant difference among the treatments. There was no influence on the order of delivery in the total number of births. In the evaluation of the pregnancy and parturition rate, there was no significant difference between the treatments, both presenting values above 90%. In the frequency distribution of animal welfare results, the results obtained demonstrated more parameters compromised in the G3 group (pre-implantation regrouped), before and after 35 days of gestation.
