During final period females males rearing, lesions determined based post-mortem carcasses. that all experimental farms, housing than norms. slightest deviation regulated indicators, ranged 16.7 37.5 age groups, form “UPG-Invest”, largest, 30.2 39.4 “Welfare”. pathology “bubbles” clinically manifested 61st day their rearing. minor incidence, 5.2 13.9 group 61–90 days, increased with and, 91 120 15.4 20.9 121 – 18.4 23.9 According such average incidence indicated groups farms 10.3, 17.4, 20.6 respectively. least affected (13.1 %) UPG-Invest where stocking exceeded maximum permissible values only 0.7–1.2 birds/m2, (18.9 farm “Dobrobut”, accommodation standards 1.3–2.6 birds/m2.
