Abstract

The extensive rearing system of became very popular in consumers as well as producers of poultry meat. Due to the fact that it is not always possible to buy birds dedicated to such kind of system typically commercial birds are used, characterized by high growth rate and good conversion ratio. Nevertheless, there is a belief that these birds have difficulty in adapting to non-optimal environmental conditions. The aim of the study was to compare the biochemical blood parameters, as a physiological indicators of proper health condition, in both, meat-type chicken and turkeys, kept in two rearing systems, intensive and extensive. Material consisted of 240 day-old Cobb 500 chickens, divided into 2 groups with 4 replications of 30 birds each. 1st group (control, CC) were fed ad libitum with balanced full-feed mixtures. 2^nd group (experimental, EC) from the 4^th wk of age was reared with the free access to the yard. The balanced mixture was weekly reduced by 10 % and replaced with wheat bran and crushed wheat. Birds were also fed with contribution of green fodder of nettle, alfalfa and grass. The experiment lasted 12th wks. The 2^nd part of experiment included 100 BUT9 turkey females, which at 6^th wk of age were randomly divided into 2 groups: control (CT) and extensive one (ET) with 5 replications of 10 birds each. In the 7^th wk of life, birds from ET group were transferred to a building with an access to runs. CT birds were given balanced diets. Birds from ET group were fed with balanced diets gradually diluted with wheat bran and crushed wheat, they were given green fodder. Turkeys were slaughtered after 16 wks of rearing. During the slaughter blood samples were collected and centrifuged. Serum parameters (AST, ALT, LDH, CHOL, UA, TG, Glu, TP, Ca, Mg, P, Fe) were evaluated. The different physiological reaction for extensive RS was registered in poultry species. The analysis showed less intensive liver function in EC, however in ET the AST level was higher. There were also different relations in case of TP, lower in EC, higher in ET in comparison to control groups, respectively. In chicken groups CHOL was similar regardless of RS, however, in turkeys it was significantly lower in birds fed with green fodder, probably due to high content of fiber applicated for longer time. In both species the UA levels were found to be reduced.
