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...
Characteristics of muscle fibers of breast and leg muscles of grey partridges Perdix perdix. The experimental material included grey partridges Perdix perdix L. planned for reintroduction into the natural habitat, reared at the Game Breeding Center on the area of Mazovia Province. 10 females and 10 males were selected for slaughter. The birds were slaughtered in poultry abattoir and specimens of their...
Effect of copper nanoparticles and copper sulfate administered in ovo on copper content in breast muscle, liver and spleen of broiler chickens. The initial experimental material included 300 hatching eggs of Hubbard Flex chickens. The eggs were divided into three groups: control, NanoCu and CuSO4. Eggs from groups NanoCu and CuSO4 were subjected to in ovo injection to the air cell of egg. Experimental...
The experimental material included grey partridges Perdix perdix planned for re-introduction into the natural habitat, reared at the Center of Game Breeding on the area of Mazovia Province. 10 hens and 10 roosters were selected for slaughter. After exsanguination, plucking and evisceration, the birds were cooled for 24 h to a temperature of 4°C. The carcasses were subjected to dissection to enable...
The experiment was conducted on 930 slow-growing chickens from the crossing of a Cobb male and Greenleg Partridge female. The chicks were randomly assigned to two groups: control (BW) which did not have access to a free run and the experimental group (W) using the grassy runs from 4 weeks of age. The experiment showed a statistical effect of sex on breast (P < 0.01) and leg (P < 0.05) muscle...
The experiment was carried out on 936 slow-growing chickens from the crossbreed of Cobb cock with Greenleg Partridge hen. Chicks were randomly divided into two groups: controlled group (BW) with no access to the field and experimental group (W) with access to grass fields since their fourth week of life. In blood serum overall cholesterol, lipoproteins with high density (HDL), triacylglycerols (TG)...
At the first stage of the study the experimental material included 300 clutching eggs of Hubbard Flex chickens. The eggs were divided into three groups: control (without injection in ovo), Nano50 (in ovo injection of colloidal copper nanoparticles) and NanoCuSO4 (in ovo injection of colloidal nanoparticles of copper sulphate). Experimental solutions were administered by in ovo injection using a sterile...
