Nutritional value variability of different poultry species meat in the organic production system. The aim of the present study was to determine the real nutritional composition for selected quality attributes of breast muscles of different organically-farmed bird species.The study covered four species of poultry – the Broad Breasted White turkey (group T), broiler chickens (group C), Muscovy ducks...
Growth performance parameters and selected quality traits of meat and femoral bone of broiler chickens fed diet supplemented with amorphous diatomaceous earth. This study was aimed at analyzing the effect of the addition of amorphous diatomaceous earth to feed on growth performance parameters and selected quality traits of meat and femoral bone of broiler chickens. The study was conducted with 60...
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...
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...
The study was conducted on 640 chickens randomly divided into two groups, each having four replications (4 control and 4 experimental - L-carnitine) with 80 chickens per pen. Chickens in the control (C) and experimental groups (E) received a feed of the same nutritional value, and chickens from the experimental group were supplemented with Aminocarnifarm (43.68% of L-carnitine) in drinking water (62...
The experiment was carried out with 320 chickens (fast-growing Hubbard Flex and slow-growing Hubbard JA 957) divided into two experimental groups, each having 160 birds in four replicates, with 40 birds per replicate. During the experiment, body weight was measured initially and at weekly intervals, and feed intake and flock health were determined to calculate feed conversion (kg per 1 kg gain) and...
