Sow and Litter Performance of Individual Crate and Group Hoop Barn Gestation Housing Systems: A Progress Report
Full recordShow full item record
AbstractThe effects of swine gestation housing on sow and litter performance were evaluated at the Iowa State University Lauren Christian Swine Research and Demonstration Farm near Atlantic, IA. The gestation housing systems were 1) individual gestation crates in a mechanically ventilated, partially slatted floor, manure flush confinement building (CRATE); and 2) group pens in deep-bedded, naturally ventilated hoop structures (HOOP). The HOOP sows were fed in individual feed stalls. The sow genotypes were 1/4 Hampshire x 1/2 Yorkshire x 1/4 Landrace. Farrowing occurred every 2 weeks throughout the year.
