Pigeons have been the subject of research in the past, but the knowledge gained is incomplete and must be extended. The aim of the study was to provide information about differences in carcass weight and measurements, carcass composition, proximate chemical composition, acidity, electrical conductivity, color attributes, the texture, rheological properties and microstructure of the meat, and some biometric characteristics of the digestive system in carrier and King pigeons, and also to determine if the two compared breeds meet the expectations of pigeon meat consumers to the same extent. The study involved 40 carcasses from carrier pigeons and King pigeons after three reproductive seasons. The chemical composition was determined by near-infrared transmission (NIT) spectroscopy, color coordinates according to CIELab, the texture according to Texture Profile Analysis (TPA) and Warner–Bratzler (WB) tests, and the rheological properties of meat according to the relaxation test. The compared pigeon groups differed significantly (p < 0.05) in carcass weight and measurements, carcass composition (except breast muscle percentage), chemical composition (except leg muscle collagen content) and electrical conductivity, lightness (L*), yellowness (b*), chroma (C*) and hue angle (h*), textural characteristics (except cohesiveness and Warner‒Bratzler shear force), rheological properties, microstructure of the pectoralis major muscle, as well as the total length of intestine and its segments, duodenal diameter, weight of proventriculus, gizzard, liver, heart, and spleen. The sex of the birds had a significant (p < 0.05) effect on the carcass weight, chest circumference, carcass neck percentage, breast muscle collagen content, and caeca length. The genotype by sex interaction was significant (p < 0.05) for fat content, collagen content, hardness, sum of elastic moduli and sum of viscous moduli of the pectoralis major muscle, protein and collagen content of leg muscles, duodenal and caecal length, jejunal and ileal diameter, and spleen weight. The obtained results show a significant effect of genetic origin and sex on the nutritive and technological value of the meat, and on the digestive system development of the pigeons.

Abstract. Forty 7-week-old ducks, 5 males and 5 females, from strains A44 and P66 and conservation flocks P33 and K2 were investigated. Their carcasses were dissected and chemical composition of the pectoralis major muscle was analysed. The carcasses of A44 and K2 drakes and ducks contained (%) significantly more pectoral muscles compared to the carcasses of P66 and P33 drakes and ducks. The carcasses of K2 males contained significantly less (%) thigh and lower thigh muscles than the carcasses of P66 and P33 males. The carcasses of K2 females had significantly less skin with subcutaneous fat compared to the carcasses of A44, P66 and P33 females. Pectoralis major muscle of drakes and ducks from conservation flocks contained more soluble collagen in total collagen than in animals from breeding strains. Moreover, the muscle of K2 males and females was found to contain more polyunsaturated fatty acids than in A44 males and P66 females, respectively. Pectoralis major muscle of drakes and ducks from both conservation flocks was characterized by a significantly lower energy value than in P66 drakes and ducks of both strains, respectively.

The pectoralis major is a widely used muscle in reconstruction surgery for replacement soft tissue defects of a head, neck, thorax, upper limbs and restoration of muscle active function. The peculiarities of anatomy of the pectoralis major makes it possible to divide the muscle into several segments with their own innervations and supply and use them independently from each other. This article describes the anatomy of the pectoralis major and the opportunity for clinical applications of different segments of this muscle. The authors demonstrate the result of the restoration of shoulder and elbow flexion in a patient with arthrogryposis due to simultaneous transfer of the proximal part of pectoralis major to the anterior part of the deltoid muscle and the distal part of pectoralis major to the biceps with good functional results. The article will be useful for plastic surgeons, orthopedic surgeons and physiotherapists.
