“…This is supported by the lack of significant changes in alkaline phosphatase activity in the blood of broilers receiving Fe-glycinate chelate compared to those receiving Fe sulphate [ 14 ] as well as the lack of variance in Zn level in blood [ 14 ] and Zn and Mg in the femoral bone [ 21 ]. In addition, few differences in the analyzed parameters found in the tibia of broilers receiving sulphate or chelate referred to improvement in those parameters, which is a particular advantage because tibia bones growing faster and being subject to higher loads due to the fact that they support the whole body weight of a bird, are more exposed to deformations (mostly dyschondroplasia) than femoral bones [ 2 , 3 , 31 , 32 ]. Attention must be paid to the significant increase in the content of Mg and Zn in the tibia of groups supplemented with Fe corresponding to 50 and 25% of the recommended requirement in comparison to those receiving Fe covering 100% of the requirement.…”

“…At the same time, the rearing period was reduced by half. However, the intensification of rearing results in the unbalanced growth of anatomical parts of the birds’ bodies, which leads to numerous irregularities, including anomalies of the skeleton, and in particular leg bones, such as deformations, infections and osteoporosis as well as tibial dyschondroplasia [ 2 , 3 ]. These pathologies are due to the fact that too intense a growth rate prevents the full maturity of the skeleton, which means that the legs are not capable of supporting the heavy-weight broilers’ body.…”

The purpose of the work was to check whether the application of Fe-glycinate chelate in mixtures fed to poultry in an amount covering 50 or 25% of the requirement would decrease the physical, morphometric and strength parameters of tibia bones in male Ross-308 broiler chickens in comparison to groups receiving Fe in an amount covering 100% of the requirement in the form of glycinate chelate or sulphate. It was found that the results for chickens from groups receiving Fe chelate covering 50 or 25% of the requirement were generally not lower than in the sulphate group and were higher than in the group receiving Fe in the amount covering 100% of the requirement. The presented results indicate that the standard requirement for Fe (40 mg kg−1 feed) as recommended by producers of Ross chickens may be too high if glycinate chelate is the source of Fe. This can be connected with the higher bioavailability of Fe from organic compounds in comparison to inorganic compounds.

“…V tretji fazi pride do pojava zelene obarvanosti mišičnega tkiva, ki se najprej pojavi v sredini mišice in se nato razširi čez celotno mišico. V četrti fazi pa je mala prsna mišica nekrozna, njena barva pa variira med belo, sivo in zeleno (Kijowski in Kupińska, 2013;Kijowski in sod., 2014).…”

In recent decades, global production of poultry meat has increased due to its affordable prices and good nutritional value. The latter has been achieved by intensive selection of broilers for increased growth rate, feed efficiency, breast yield and reduced abdominal fat deposition. On the other hand, intensive selection and increasing demand for poultry meat, as well as some environmental stressors, such as changes in environmental temperature, feeding regime, breeding technology, and improper handling procedures before slaughter, lead to increased susceptibility of animals to oxidative stress, resulting in poorer sensory and technological characteristics of chicken meat. As a result of intensive broiler production and the increase in breast muscle, various breast muscle abnormalities or myopathies have been observed. The most common ones include deep pectoral myopathy, pale, soft and exudative like meat, white striping, wooden-breast and spaghetti meat, which mainly affect the pectoralis major breast muscle and negatively influence the sensory and technological characteristics of breast meat. The muscle abnormalities have a detrimental effect on quality and nutritional value of meat, affect consumer compromise consumers acceptance, and cause economic losses in the meat processing industry.

the objective of the paper was to demonstrate the possibilities of using polish native breeds of chickens for the production of meat for its specific quality features in the light of worldwide researches. The object of the analysis was the quality of meat from slow-growing chickens raised in varied housing systems, including capons and poulards. The findings of studies on the quality of poultry meat from native breeds obtained from post-production cockerels and from hens in their post egg-laying stage have shown that there are chances for their use in meat production. Native breed hens can also be used as foundation material for the production of capons, poulards or international mixed breeds for purposes of extensive farming. The body weight of native breed hens, including their muscle build depend on the bird's genotype, feeding, length of exploitation and farming system. Meat from native breed hens, raised in free-range systems has less fat, but with higher polyunsaturated fatty acids in their meat muscles as well as a healthier ratio of n-6/n-3 PUFA acids. Outdoor free-range access influences the meat colour, i.e., bright coloured breast muscle (L*) as well as increased intensity of red coloration of leg muscles (b*). Caponisation of hens enhances intensified body weight gains along with increased fattening of meat. In comparison with cockerel meat, the meat of capons is more juicy, tender and of better taste, while poulard meat has distinctively favourable sensory values in comparison with broiler chicken meat.
