The aim of the present study was to evaluate the degree of microbial air contamination in three laboratory rooms designed for raising broiler chickens under identical conditions, in the summer and winter. It was found that in identical poultry houses and under identical management conditions, certain differences can be observed with regard to temperature and humidity parameters and the degree of microbial air contamination, both in the summer and winter. The concentrations of aerobic mesophilic bacteria and fungi were higher in the winter than in the summer in all rooms. Various levels of microbial air contamination had no effect on broiler production results.

The effect of a housing system on production results and slaughter analysis of slow-growing chickens. The study covered 720 Cobb x Zielononóżka kuropatwiana (Cobb x Zk) chickens reared until the 63rd day of life. On the day of introduction to a hen house, the chickens were randomly divided into 2 groups: a control group (reared indoors – ID, 360 birds) and an experimental group (reared with outdoor access – OD, 360 birds), with 5 replications in each group (72 birds). The differentiating factor in the study was the possibility of using grassy free ranges up to the 28th day of life in the OD group. Individual body weight, feed intake and mortality rate were monitored throughout the production period. On day 63, 20 birds were selected at random from each group for slaughter (10 cocks and 10 hens, 2 from each replication). The selected birds had body weights similar to the average body weight for a given sex in a group. In total, 40 carcasses were dissected. The study demonstrated a significant (P≤0.05) effect of the access to a free range on the final body weight of hens. The housing system affected also the mortality rate of Cobb x Zk chickens. The birds having the access to the free range were characterized by a significantly (P≤0.01) lower mortality rate (0.55%) compared to the control birds (1.11%). In addition, the study showed a significantly (P≤0.01) lower carcass weight of cocks from the experimental group (OD, 1491g) compared to cocks from the control group (ID, 1530g) and a significantly lower weight of breast muscles (317g and 338g, respectively). A similar tendency was observed in the case of hens, namely a lower carcass weight, breast muscle weight and fat weight in the group having access to grassy free ranges.The housing system had a significant effect of growth of the body weight of hens having the possibility of using grassy free ranges. The Cobb x Zk chickens characterized by high dressing percentage, similar contents of breast muscles and leg muscles as well as good health status, may be used as material for the rearing free range.

The study was carried out on 4200 turkey broilers Big 6, from which after a 3-week breeding an experimental group was separated. The group was receiving an addition of bioplex-Cu 0.5g/L of drinking water till the end of the experiment. The haematological and biochemical factors were examined in the 8th week of the turkeys life, in blood taken from the wing vein of 10 randomly chosen birds (5 cocks and 5 hens) from both experimental and control group. In the obtained samples, Ht, total protein level, a-NH2 nitrogen, glucose, and the Cu, Fe, Zn and Ca level were determined. Also, in the bioplex-Cu and in the feeds used, Cu, Fe, Zn and Ca were determined by the spectrophotometry of atom absorption method after dry mineralization. The applied bioplex-Cu statistically significantly increased the haematocrit and glucose level. The addition of Cu also caused an increase in the concentration of this element in the plasma of turkey blood. The significantly increased Cu level did not cause interaction with other components of the feed and did not disturb the Fe, Zn and Ca absorption to the turkey blood.
