Project description: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.

Project description:The protein sources in feed have a huge impact on good-quality and -quantity meat traits. Yellow lupin (YL) seeds have a similar level of protein as soybean meal (SBM). The most popular is SBM that is genetically modified (GMO). During this age, the consumer market requires non-GMO products. Yellow lupin used as a high-protein substitute for SBM in feed has an effect on the quality of meat from broiler ducks. The aim of the study was to analyse and compare meat quality traits in breast and leg muscles as well as fatty acid (FA) composition in breast muscles from ducks fed mixtures containing YL as an alternative to SBM. Two hundred 1-day-old Cherry Valley ducks were kept in pens on litter in two equal dietary groups, four replications with 25 birds per group. The control group (1) received balanced feed containing SBM. The treatment group (2) received balanced feed containing YL. The feed provided to both groups contained 55% of concentrate and 45% of wheat. Birds received feed and water ad libitum and were reared for 8 weeks. After that, 16 ducks (eight from each group) of BW close to the mean for the whole group were slaughtered. Plucked and gutted carcasses were analysed in a laboratory for quality parameters. Meat was analysed for pH, colour, water-holding capacity and drip loss. Samples of breast muscles were analysed for the content of cholesterol, collagen, intramuscular fat and FA composition. The proposed feed mixture containing YL had no impact on meat traits, content of muscles or fat in duck carcasses (P > 0.05). The values of lightness (L*) and yellowness (b*) and collagen content in breast muscles were significantly higher (P < 0.05) in group 2 (YL). A lower ability to retain water, that is, higher water-holding capacity (percentage of water lost from meat) (P < 0.05), was found for leg muscles from group 2 (YL). The content of C16:0, C18:0, C20:4 n-6, C22:4 n-6, C22:5 n-3, total content of saturated fatty acids (SFA), values of atherogenic index and thrombogenic index were significantly lower (P < 0.05) in group 2 (YL) than in group 1 (SBM). The content of C18:2 n-6 and the polyunsaturated fatty acids-to-SFA ratio (P/S) were significantly higher (P < 0.05) in ducks fed the diet with the inclusion of YL. Diets with YL could be proposed as a partial substitute for SBM in duck-rearing.

Project description:The aim of the study was to compare the carcass and meat quality of geese fed with soybean meal or yellow lupin. In total, 210 White Ko?uda® geese were divided into 2 groups (1, soybean meal (SBM); 2, yellow lupin (YL), potato protein, and brewer's yeast) of 5 replications (21 birds per each). After 16 weeks, 10 geese (5 females, 5 males) from each group were slaughtered. Carcass dissection was done, and major physicochemical traits were analysed (pH, water holding capacity, drip loss, color, and chemical composition of muscles). Weight of leg muscles and their proportion in the carcass were higher (p < 0.05) in SBM. Breast muscles from SBM were characterized by increased (p < 0.05) drip loss, enhanced (p < 0.05) content of protein, water, collagen and connective tissue, and lower (p < 0.05) fat content. Leg muscles from SBM were characterized by higher (p < 0.05) protein and water content but decreased (p < 0.05) salt and fat content compared to YL. The addition of YL (approx. 28%), potato protein, and brewer's yeast had no negative effect on most meat traits and could partly replace SBM as a protein source in geese feeding. Hence, yellow lupin, potato protein and brewer's yeast can be used in geese rearing followed by fattening with oats. Some producers do not have the option of using soybean meal. Small-scale farms use their own crop resources, so lupins can be an alternative source of protein for soybean meal.

Project description:The aim of the study was to analyze the quality of geese meat receiving feed with soybean meal (group 1), yellow lupin (group 2), narrow-leaved lupin (group 3), or white lupin (group 4). In total, 400 male White Ko?uda® geese were randomly assigned to four groups, with 10 replicates and 10 birds each, during the 77-day rearing period. After the end of the rearing period, 10 birds from each group were slaughtered and dissected. Meat quality traits were measured. Based on the production results, it can be concluded that geese use fodder with yellow and white lupin to the same degree as in the case of the control group and higher body weight gain was recorded in the first rearing period. In contrast, the use of narrow-leaved lupin in mixtures for geese worsened the feed used. Meat traits were similar in all groups, including the content of muscles and fat in the carcass (p > 0.05), excluding abdominal fat. The weight of abdominal fat and its proportion in the carcass were higher (p < 0.05) in geese from group 4. A higher (p < 0.05) pH was found in group 1. The protein and intramuscular fat content in breast muscles was highest (p < 0.05) in geese from group 4, and a higher water content was found in group 1. The protein content in leg muscles was higher in group 3, and the fat content was higher in group 4 (p < 0.05). The color and water-holding capacity of meat were comparable in all groups (p > 0.05). The analysis revealed a positive effect of replacing soybean meal with alternative protein sources, especially yellow and white lupin, on the growth performance and quality of goose meat.

Project description:This study aimed to investigate the effects of different dietary levels of blue lupine (Lupinus angustifolius) seed meal with or without probiotics (Bacillus subtilis) in broiler diets on the growth performance, carcass characteristics, internal and immune organs, and gut morphology. Three experimental diets containing 0, 20, and 30% of blue lupine, with or without probiotics, were formulated and fed to 144 day (d)-old Ross 308 broiler chickens. Overall, chicks fed blue lupine meal diets, especially at the 30% rate, showed improved growth, feed performance parameters, and carcass characteristics in comparison to chicks fed a soybean meal-based diet. For example, a 30% blue lupine diet resulted in a significant increase in the duodenum length percentage of 35 d-old broilers; the addition of probiotics had no-effects on the dressing, thigh, and leg percentages of 21- and 35 d-old broilers and the drumstick and leg percentages of 35 d-old broilers. In conclusion, a 30% blue lupine seed diet with the addition of probiotics could provide a cheap source of protein without negative effects on the growth performance, carcass characteristics, immune organs and gut morphology of broilers.

Project description:The current practices of the poultry industry have raised concerns among consumers. Among these is the culling of day-old male chicks of laying hybrids; a suitable alternative for this could be the use of dual-purpose breeds where both sexes are used. Another practice that causes concern is the import of large quantities of soybeans for feedstuff production. Substitutes for these soybean-based products are regional protein crops, such as faba beans (Vicia faba L.; FBs). The objective of this study was to test the suitability of FB as a locally produced soybean meal replacement for two local dual-purpose chicken breeds and one high-performing layer line. The breast and leg meat of male Bresse Gauloise (BG), Vorwerkhuhn (VH), and White Rock (WR) animals was evaluated for different meat quality parameters: pH, color, water holding capacity, and tenderness. Sensory properties of the samples were evaluated by a trained panel with a conventional descriptive analysis. Results show different effects of FB diets on meat quality parameters in the different breeds. The attributes mostly affected by the diet are related to aroma, flavor, and texture, particularly in VH and WR. Overall, faba beans appear to be an acceptable dietary protein source for rearing these breeds for meat production.

Project description:A meta-analysis was conducted (i) to evaluate broiler response to partial or total substitution of corn by sorghum and millet and (ii) to determine the effect of soybean meal replacement by cottonseed meal in broiler diet. The database included 190 treatments from 29 experiments published from 1990 to 2013. Bird responses to an experimental diet were calculated relative to the control (Experimental-Control), and were submitted to mixed-effect models. Results showed that diets containing millet led to similar performance as the corn-based ones for all parameters, whereas sorghum-based diets decreased growth performance. No major effect of the level of substitution was observed with millet or cottonseed meal. No effect of the level of substitution of sorghum on feed intake was found; however, growth performance decreased when the level of substitution of corn by sorghum increased. Cottonseed meal was substituted to soybean meal up to 40% and found to increase feed intake while reducing growth performance. Young birds were not more sensitive to these ingredients than older birds since there was no negative effect of these ingredients on performance in the starter phase. Results obtained for sorghum pointed out the necessity to find technological improvements that will increase the utilization of these feedstuffs in broiler diet. An additional work is scheduled to validate these statistical results in vivo and to evaluate the interactions induced with the simultaneous inclusions of sorghum, millet and cottonseed meal in broiler feeding.

Project description:An experimental study was conducted to examine the combined effects of adding a dietary protease, reducing the levels of soybean meal (SBM) and introducing corn gluten meal (CGM) in the ration of a group of broilers reared on a commercial Greek farm. Five hundred forty chicks were divided into three dietary treatments with six replicates of thirty birds each. The first group (Control) was fed a conventional diet based on corn and soybean meal, containing 21% w/w crude protein (CP). The second group (Soy-Prot) was supplied a corn and SBM-based diet containing a lower level of CP (20% w/w) and 200 mg of the protease RONOZYME® Proact per kg of feed. The third group (Gluten-Prot) was fed a diet without soybean-related constituents which was based on corn and CGM and with CP and protease contents identical to those of the diet of the Soy-Prot group. Body weight, feed intake, feed conversion ratio (FCR), intestinal microbiota populations and morphology, meat quality and cost were evaluated. Furthermore, a partial life cycle assessment (LCA) was performed in order to assess the potential environmental performance of the systems defined by these three dietary treatments and identify their environmental hot-spots. The growth performance of the broilers supplied the Soy-Prot diet was similar to the broilers supplied the Control diet. However, the broilers which were fed the Gluten-Prot diet at the end of the trial showed a tendency (P?0.010) for lower weight gain and feed intake compared to those of the Control diet. When compared to the Control group, lower counts of C. perfringens (P?0.05) were detected in the ileum and cecum parts, and lower counts of F. necrophorum (P?0.001) were detected in the cecum part of the birds from the Gluten-Prot group. The evaluation of intestinal morphometry showed that the villus height and crypt depth values were not significantly different (P>0.05) among the experimental groups for the duodenum, jejunum and ileum parts. No significant differences (P>0.05) were observed in the quality of the breast and thigh meat and in the feed cost per kg body weight gain for the total duration of the growth period between the Control and Gluten-Prot broiler groups. The LCA suggested that the ammonia and nitrous oxide emissions due to litter handling constitute the farm level hot-spots for the Acidification and Eutrophication Potentials of the Control and Soy-Prot systems and the Global Warming Potential of the Gluten-Prot system, respectively. The Latin American soybean production and domestic corn production and lignite mining are important off-farm polluting processes for the studied life cycles. The Soy-Prot and Gluten-Prot systems both performed better than the Control system in nine of Environmental Impact Category Indicators assessed, with the respective differences being generally larger for the Gluten-Prot system. The environmental impact estimates are regarded as initial, indicative figures due to their inherent uncertainty. Overall, the results could be considered as positive indications in the effort to sustainably replace the conventional, soybean-dependent control diet in the specific broiler production system.
