ABSTRACT:
Welfare in poultry on farms in regulated by EC Regulations 1274/91 and 788/95 and EC Directive 199/74. Welfare of broilers chickens on farms was estimated by 110 direct and indirect indexes of importance. On the tested farms litter housing of broilers was applied 50% of broiler chickens in daytime were inspected no less than 2 times, in all the remaining cases – at least twice daily. The minimum 10 lux artificial lighting required for the staff to evaluate the state of birds at any time of the day was registered in 66.7% of all the tested farm. 16.7% of farms have no artificial lighting or it is insufficient. "All in – all out" technique is applied in all poultry farms owned by agricultural or individual enterprises. However, small poultry farms have no possibilities to apply this technique. Mechanical ventilation capacities are sufficient to meet hygiene requirements for air changes or microenvironmental parameters in 90% of the poultry farms owned by agricultural or individual enterprises. Relative air humidity in autumn months was from 79.0 to 87.7% in 54% of the tested farms and exceeded the optimum (60-70%) standards. Dust concentration was from 0.03 to 16.4 mg/m3 in the premises for broiler chickens and replacement pullets. Ammonia concentration exceeded 40 ppm limit in 16.7% of all tested poultry houses, 20 ppm in 33.3% of farms and did not reach the level of 10 ppm in all the remaining cases. All the tested farms carry out disinfection and deratization every year. Attention should be paid to the feet problems of young birds, ascites, sudden death syndrome and monotonous feeding.
