The aim of this study was to compare the growth performance parameters, carcass quality, and meat traits in broiler chickens fed on diets containing legume seeds and rapeseed meal as an alternative to soybean meal. In this study, 448 male ROSS 308 chicks were divided into subgroups: a control group (I) fed on soybean meal (SBM), and six experimental groups II—rapeseed meal (RSM); III—white lupin (WY); IV—yellow lupin (YL); V—narrow-leaved lupin NLL; VI—pea (Pe); and VII—faba bean (FB). After 42 days of rearing, 10 birds from each group were slaughtered and dissected. The control group was characterized by better growth performance compared to the other groups. In addition, the European Broiler Index was lower in each experimental group compared to the SBM group. A lower dressing percentage was found only in the NLL group. The muscle content in birds from the RSM and FB groups was significantly higher than in the other groups, but the fat content was lower. Meat from SBM group was characterized by the highest protein content, but a reduced content of fat and water in the muscles. The most similar results were found between the control group and the FB group receiving a diet based on faba beans. Furthermore, lupins had a similar effect on the carcass traits when used in the diets. The quality of meat in broilers fed on faba beans with the addition of potato protein and brewers’ yeast was similar to that of those fed on soybean meal, because the antinutrients were the lowest in faba bean seeds. Faba beans are proposed as a possible alternative source of protein in poultry diets. Other legume seeds should be analyzed in future studies.

Pheasant eggs evaluated in the first period of egg-laying did not differ significantly in their weight and shape index and the values of both traits were, respectively, 30.7 to 32.2 g and 76.1 to 78.1%. Over the laying season the thickness of the shell decreased and its capacity for deformation and crush strength were greatest at the end of the laying season. The share of yolk in the egg was highest at the beginning of the laying season (35.3%), however over the peak of egg-laying and its final period the content of the albumen in the egg and the quality of eggs, expressed in Haugh units, increased. The best egg fertility and the results of chick hatch were observed from eggs collected at the beginning of the laying season (respectively, 92.5 and 81.6%) and about the fifth week of production (respectively, 94.4% and 73.9%). Chicks hatched from eggs collected at the early laying season were heaviest (21.5 g) and showed the highest share in egg weight (66.8%).

Goose meat is characterized by good quality and a good fatty acid composition. Geese do not need many compounds in their feed to ensure suitable growth. The main source of protein in most feed is soybean meal ( SBM ). New cultivars of yellow lupin with fewer antinutrients could be a substitute for soybean. The study's aim was to compare the quality of the carcass and meat, as well as the fatty acid composition and the collagen and cholesterol content in the breast muscles from geese fed a diet based on yellow lupin as an replacement for soybean meal. In the study, geese were divided into 2 study groups. The first was a control group (Group 1), fed a feed based on SBM; the second one was an experimental group (Group 2), fed a feed based on yellow lupin “Mister”, potato protein, and brewer's yeast. The rearing period was divided into 3 stages, and the last stage was oat fattening. Each group (105 birds in each group) was divided into 5 replications with 21 birds. After 16 wk of rearing, 10 geese from each group were slaughtered. The carcasses were analyzed for physicochemical traits (dissection, color, water-holding capacity, and chemical composition of the breast and leg muscles, as well as pH level, drip loss, and fatty acid profile of the breast muscles). The drip loss from the breast muscles was higher ( P < 0.05) and the water-holding capacity of the leg muscles lower ( P < 0.05) in Group 1 than in Group 2. Group 1 also displayed a higher content of protein and water in breast and leg muscles ( P < 0.05) but lower fat content than that of Group 2 ( P < 0.05). The linoleic acid content of the breast muscles was higher in Group 2 ( P < 0.05), whereas the other fatty acid levels were comparable between the groups. The total content of polyunsaturated fatty acid ( PUFA ) (n-6 and n-3) and the PUFA/ saturated fatty acid ratio was higher in Group 2 ( P < 0.05). Moreover, the thrombogenic index was lower ( P < 0.05) in the geese fed a lupin-diet. Overall, the yellow lupin–based feed had beneficial effects on the goose meat's traits, and it can be used as a high-protein compound in diets for geese. It is also possible to produce traditional geese fattened by oats.
