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 pectoral superficial muscle (pectoralis superfi cialis) and biceps femoris muscle (biceps femoris) were sampled. A greater diameter of fibers was determined for breast muscles. The study did not show any effect of sex on muscle fiber diameter of breast and leg muscles of grey partridges Perdix perdix.

Proteolysis and lipid oxidation in the vacuum-packed leg and breast muscles from Mullard drakes stored at 1°C were studied. As proteolysis indicators there were determined proteolytic activity, contents of amino nitrogen and free amino acids (FAA), and TBARS values as indicators of oxidative changes. Changes were also determined in the proteolytic activity, TBARS values and contents of: amino nitrogen and FAA. As a result, 18 FAA were found in breast muscles and 19 in leg and their total contents after 1 day of storage were 184.39 mg/100 g tissue, and 233.33 mg/100 g tissue (respectively). In the case of breast muscles a significant increase in the content of detected FAA (except Pro) was noted after 13 days of storage and in the leg muscles (except Asp) after 5 days of storage. It was established that the proteolytic activity decreased (ca. 38%) in breast after 18 days and in leg (ca. 30%) after 5 days of storage. The content of amino nitrogen significantly increased in breast muscles after 18 days and in leg muscles after 5 days of storage. During storage, TBARS values were observed to increase continuously in breast muscles, whereas in legs they first increased after 5 days and then were observed to decrease.

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 fiber diameter in CobbxZk hybrid roosters. There were no significant gender-dependent differences in the surface area of the muscles tested. No effect was either reported of the rearing system on the histological picture of breast and leg muscles.

The experiment was conducted with 60 slow-growing Hubbard JA 957 broilers and with 60 Silkies chickens reared until the 63rd day of life, in three replications, 20 birds each, in a closed building on litter. A three-stage feeding program was applied in the rearing period. Feed mixtures used in the experiment did not differ in contents of nutrients. In the first stage of rearing (till 21 days of life) the chickens were fed a standard starter feed mixture containing: 20.98% of total protein, 2,845 kcal/kg of me-tabolizable energy, 1.17% of lysine and 0.98% of met. + cys. In the period from 22 to 56 days of life they were receiving a grower type mixture containing: 20.0% of total protein, 2,900 kcal/kg of energy, 1.04% of lysine and 0.88% of met. + + cys., whereas contents of these components in the finisher type mixture administered till the end of the rearing period were as follows: 18% of protein, 2,965 kcal/kg of EM, 0.90% of lysine and 0.78% of met. + cys. On day 63 of rearing, 12 cockerels and 12 hens were selected random from each group. The birds were slaughtered in a poultry slaughter house, and specimens of their major breast muscle (m. pectoralis superficialis) and thigh muscle (biceps femoris) were sampled for analyses. The breast and leg muscles of the birds were characterized by diversified diameters of muscle fibers depending on bird genotype. The greatest diameters were found in breast and leg muscles of the slow-growing Hubbard JA 957 broilers, which was confirmed statistically (P < 0.01). It was also demonstrated that the mean diameter of muscle fibers of Silkies chickens was more than two times smaller compared to the Hubbard JA 957 chickens.

The study was conducted on 300 turkey cocks type BUT-9, grown under optimal conditions for this kind of poultry. The feed was a typical commercial full-dose mix for turkeys. The birds were divided into 5 experimental groups. From the 3rd week of their life, they were given preparations with their drinking water. Group I was the control group, while drinking water for the test groups was enriched as follows: lactic acid (0.4%) for group II, CuSO4 in the amount of 30 mg Cu·dm-3 H2O for group III, CuSO4 (30 mg Cu-dm-3) and 0.4% of lactic acid for group IV and CuSO4 in the amount of 50 mg Cu·dm-3 for group V. Application of the preparations was terminated after 3 days, when symptoms of poisoning were observed in turkey cocks of groups II and IV, alongside increased mortality rate. Samples of drinking water were taken for analyses, and from each group 10 birds were selected for slaughter to take tissue samples (breast and leg muscles). The objective of the experiments was to determine the concentration of Ca, Mg, Zn, Cu and Fe in the consumable tissues of turkey cocks. The study showed that the highest rate of mortality of turkey cocks was observed in the group that was given lactic acid with their drinking water, and these turkeys had increased levels of Ca, Cu, Zn and Fe. In none of the groups, the content of Zn in the breast muscle exceeded 20 mg kg-1, while the concentration of copper in all experimental groups (except the control) was above the level of 10 mg kg-1. Increased doses of copper caused an increase in the concentration of magnesium in the leg muscles, while a combination of copper supplementation with lactic acid resulted in increased accumulation of Cu in both the breast and leg muscles.
