“…The values of body conformation indices, sternum crest length and chest circumference were higher in female ducks. Experiments conducted by Kokoszyński and Bernacki 23 conducted on P44 and P55 ducks revealed lower values compared to those found in our study.…”

Duck meat enjoys growing popularity among consumers. Alternative protein sources to soybean are being investigated to eliminate genetically modified components from the poultry’ diet. The aim of this study was to compare growth performance, quality of meat, and fatty acid composition in subcutaneous and abdominal fat from ducks fed a diet based on yellow lupin and rapeseed meal, sources of protein alternative to soybean meal (SBM). Ducks were allocated to different dietary treatment groups and reared for 8 weeks (N = 102 per group). Group A received a diet based on SBM, while group B was fed a diet based on yellow lupin with the addition of rapeseed meal. Both groups were divided into two subgroups, of male and female birds. Growth performance parameters and zoometric traits of ducks were monitored during the growth period. After 8 weeks selected birds were slaughtered and dissected (N = 10 per group). Carcass composition was calculated and selected traits of meat quality important for further processing were analysed. Subcutaneous and abdominal fat were collected to analyse fatty acid composition. The alternative diet had no negative effect on ducks’ growth performance parameters and dressing percentage. The replacement of SBM with yellow lupin and rapeseed meal increased n-3 fatty acid content, which is important for consumers. In conclusion, SBM can be replaced with feed containing 60.10% of yellow lupin and 14.00% of rapeseed meal in concentrate. These sources of protein are mainly recommended for small poultry farms, which do not always have access to SBM and prepare poultry feed from their own crops.

“…Moreover, no difference (p > 0.05) was found in most of morphological traits between Pekin and Mulard ducks, except for LT and LS values, which were higher (p < 0.01) in Mulard ducks. The result of the present study confirms the previous observations that duck origin influenced BW and body dimensions (Solomon et al 2006;Bernacki et al 2008;Kokoszy nski & Bernacki 2011). Additionally, interactions between age Â origin (p < 0.01) were observed for all evaluated traits.…”

The main aim of the study was to estimate the polymorphism of prolactin (PRL) gene and its relation with some morphological traits (body weight-BW, length of trunk with neck-LTN, length of trunk-LT, chest girth-CG, length of breast bone-LBB, length of shank-LS) of Muscovy, Pekin and Mulard ducks. A secondary objective of this study was to evaluate the effect of age, origin on ducks' growth performances. Three genotypes at locus PRL/XbaI and one genotype at locus PRL/PstI were found. The results showed that Pekin ducks with the PRL/TT genotype in selected terms of evaluation characterised by higher (p < 0.05) LS and LBB values than those with the PRL/TG genotype. In Mulard ducks, PRL/XbaI polymorphism had an effect (p < 0.05) on BW and LS in birds aged 10 and 12 weeks (wk). The effect of age, origin on the growth traits of ducks was evaluated as well. All growth traits examined significantly increased with age. There was a significant (p < 0.01) effect of the ducks' origin. Until the 7 wk of age, the Muscovies were lighter and had lower (p < 0.01) values of LTN, LT, CG, LBB, LS than Pekin and Mulard ducks. The results confirm that there were significant associations between interaction of considered factors and estimated traits.

“…In all the compared groups of ducks, the percentage of skin with subcutaneous fat and abdominal fat was relatively low. The percentage of skin with subcutaneous fat in eviscerated carcass with the neck from the analyzed strain ducks did not exceed 25% and was lower than in the experiments by Gornowicz (2011) and Kokoszyński and Bernacki (2011) . The percentage of skin with subcutaneous fat was higher in male than in female carcasses (mean for 3 strains), which is in contradiction with the dissection results for 8-week-old ducks of the same genotype ( Gornowicz and Szukalski, 2015 ).…”

The aim of the study was to compare P33 (Polish Pekin), P8 (Danish Pekin), and LsA (English Pekin) ducks after 2 reproductive seasons for carcass composition and some meat quality traits. A total of 48 duck carcasses (8 male carcasses and 8 female carcasses of each genotype) were studied. Whole carcasses were dissected, and pH and electrical conductivity of the breast and leg muscles were determined 24 h postmortem. After dissection, breast and leg muscles were sampled to determine proximate composition, some minerals, and physicochemical properties. Breast muscles were also analyzed for textural characteristics, microstructural characteristics, and rheological properties. At 112 wk of age, genotype and sex were found to have no significant effect on carcass weight and percentage of carcass components. The genotype of the birds had a significant effect on the water and fat content in the pectoral and leg muscles, as well as protein and collagen in the leg muscles. The origin of the ducks had a significant impact on the magnesium content in pectoral muscles and Warner–Bratzler shear force pectoralis muscle major, as well as the electrical conductivity of the leg muscles. The differences in duck genotype had a significant effect on the sum of elastic moduli, fiber cross-sectional area, fiber perimeter, and vertical fiber diameter of pectoralis major muscle. Regardless of the genetic origin, breast muscles from 112-week-old males had a lower fat content, and male leg muscles contained more water and protein and less fat and collagen than the female muscles. The genotype by sex interaction was significant for the content of breast muscles, skin with subcutaneous fat, and neck percentage and for the water and fat content in breast and leg muscles.
