Influence of graded inclusion of white lupin (Lupinus albus) meal on performance, nutrient digestibility and intestinal morphology of broiler chickens

Modification of the Protein Amino Acid Content in Hen Eggs as a Consequence of Different Concentrations of Lupine and Soy in Feed

The effect of the diet modification (soybean and lupine addition) on the content of protein and amino acids (AA) in eggs was studied. Both the sampling day and the diet influenced the total protein content. In albumen, the lowest protein content (10.6%) was noted after administering a diet containing 25% lupine; in the same egg the yolk contained the most proteins (16.7%). In the content of nonessential AA (NAA) in egg yolks, differences were noted only for cysteine, with its the highest content in the yolks of the control group. The stable content of essential yolk amino acids (EAA) was observed only for isoleucine, leucine, tryptophan and phenylalanine. The highest contents of EAA and NAA were recorded in the yolks of the control group (~47 and ~53 g/100 g of protein, respectively) and in the group with 25% additions of lupine (~42 and ~51 g/100 g of protein, respectively). AA with constant content in the tested albumens were methionine, tryptophan and alanine. The highest content of EAA (>~42 g/100 g of protein) and NAA (>~62 g/100 g of protein) were determined in albumen of eggs determined in the group with at least 20% additions of lupine. The highest content of EAA for humans delivered eggs from groups 4-6 (with the addition of soy into the diet ≤5%). The protein sources used in the hen diet significantly influenced the content of protein and individual AA in the produced eggs.

Housing and dietary effects on production performance, quality index, and chemical composition of Japanese quail eggs

Quail housing and diet significantly impact egg yield and quality. This study assessed the impact of diets and housing arrangements on Japanese quail's egg production, egg index, and quality. In two trials, birds were reared in cages and on the floor with a commercial layer diet (CLD), and an experimental diet (ED) for 32 weeks. Compared to floor-reared birds, cage birds achieved 50% egg production and sexual maturity first. With dietary effects, the CLD diet showed similar results. Furthermore, their feed efficiency, hen house egg production (HHEP), and hen day egg production (HDEP) were significantly higher in cage birds that consumed CLD. Bird livability was unaffected by the housing system, while birds fed CLD had longer lifespans. The housing system had no discernible effects on egg dry matter (DM), crude protein (CP), crude fat (CF), or ash percentage. Nevertheless, the egg albumen's DM, CP, ash%, yolk's DM, CP, and CF were greater in the birds fed CLD. Barring shell thickness, weight, and Haugh unit, birds raised in cages exhibited higher egg exterior index values. Besides the yolk ratio, yolk index, and albumen weight ratio, birds given CLD exhibited enhanced egg interior quality. Ultimately, the most optimal egg production performance, improved egg quality, and prolonged lifespan of Japanese quail were obtained with cage raising and feeding practices utilizing CLD.

Feeding Value of Lupins, Field Peas, Faba Beans and Chickpeas for Poultry: An Overview

Grain legumes are fair sources of protein, amino acids and energy, and can be used as a replacement for soybean meal in poultry feed formulations as the soybean meal becomes short in supply and costly. However, a concern associated with the use of grain legumes in poultry feeding is the presence of antinutritional factors. The effective processing and utilisation of these grain legumes in poultry feeding are well documented. The current review focuses on four selected grain legumes (lupins [Lupinus albus and Lupinus angustifolius], field peas [Phaseolus vulgaris], faba beans [Vicia faba] and chickpeas [Cicer arietinum]) and their nutrient content, the presence of antinutritional factors, processing methods and feeding value, including updated data based on recent research findings.

Egg quality depending on the diet with different sources of protein and age of the hens

Due to the planned limitations in the use of genetically modified soybean meal, the search for alternative sources of protein in animal nutrition is ongoing, which also supports the consumers’ expectations of good quality products, such as eggs. The aim of the study was to assess and compare morphological traits of eggs, fatty acid composition in yolk lipids, and the content and activity of lysozyme in thick and thin albumen in eggs from hens fed a diet based on legume seeds as a substitute for soybean meal depending on the hens age. Analyses were carried out for 300 eggs on dates I–V (19–39 weeks age of hens), obtained from Rosa 1 hens managed in the semi-intensive system. Quality analysis was performed for 30 eggs from each group at a time. The control group of hens (A) was fed a diet based on soybean meal (SBM) and the treatment group (B) was fed a diet based on seeds from narrow-leaved lupin (Boruta), yellow lupin (Mister), and pea (Muza). Eggs were analysed for morphological traits (egg weight, the weight and density of egg components, egg shape index and egg surface area), parameters of albumen (height, Haugh units), yolk colour (La Roche, colorimetry in the CIE Lab system), lysozyme content and activity in albumen, and fatty acids composition in yolk lipids. In group B the egg shape index was higher (p = 0.002), and the eggshell colour index was lower (p = 0.007), as well as the height of thick albumen, Haugh score, and yolk colour (La Roche) were higher in group B (p < 0.05), while redness of yolk was significantly lower (p < 0.001) than in group A. Lower content of C15:0 and C18:1n9 and higher content of C18:2n6 and C18:3n3, (p < 0.05), as well as lower content of MUFA and OMEGA 9, but higher content of PUFA, OMEGA 3, OMEGA 6, PUFA/SFA, OMEGA 9/6 and OMEGA 9/3 were found in group B compared to group A (p < 0.05). There were significant differences in traits between age of hens (p < 0.05). Egg weight, yolk weight and its proportion in egg, as well as shell weight, its strength and thickness increased with the age of hens (p < 0.05). The content of lysozyme and its activity were also higher in eggs from older hens (p < 0.05). Fatty acids composition was beneficial at the beginning and end of the analysed egg production period. The proposed feed mixture based on legume seeds had no negative effect on the quality of eggs, and had a positive effect on yolk colour, the quality of albumen. There was no detrimental effect of diet and age of hens on fatty acid composition of eggs from both groups throughout the study period. To sum up, diet with legume seeds could be accepted as a substitute for soybean meal, due to the beneficial effects for some mentioned traits of eggs. Use of legumes could give a partial self-sufficient for producers from small farms, where is not possible to produce soybean meal. At the same time, the level of anti-nutrients in legumes should be considered.

Microbial Phytase Improves Performance and Bone Traits in Broilers Fed Diets Based on Soybean Meal and White Lupin (Lupinus albus) Meal

For several years in Europe, there has been a growing interest in the use of native sources of protein (e.g. lupin seeds) in poultry nutrition. The current study aimed to investigate the effectiveness of a microbial phytase in broiler diets with the addition of different levels of white lupin seeds. A total of 480 one-day-old male broiler chickens (Ross 308) were randomly divided into six dietary treatments (10 replications/8 birds per group). The basal diet contained SBM as the main protein source and experimental treatments were prepared with white lupin meal (WLM) at 3 levels (0, 10, and 20%) and with or without phytase inclusion. The experiment was divided into two feeding periods: from 1 to 14 days (starter) and from 15 to 35 days (grower). Diets with phytase addition were deficient in Ca and non-phytate P. All diets were fed in mash form and offered ad libitum. On day 35 excreta were collected and on day 36, ten chickens from each group were euthanized and blood, tibia, and digesta samples were collected for further analysis. The 20% addition of WLM negatively increased the content of phytic-P. The results showed that feed conversion ratio (FCR) and body weight gain (BWG) were not affected by phytase inclusion but by the WLM level alone. In addition, birds fed the diet with 20% WLM were characterized by having the lowest BWG and the highest FCR of all groups. There were no significant differences in feed intake (FI) among chickens fed control and experimental treatments. Regardless of the white lupin level addition, phytase addition improved (P<0.001) nitrogen-corrected apparent metabolizable energy (AMEN). In conclusion, the addition of phytase positively influenced the performance and availability of minerals (Ca and P) regardless of the level of WLM used. However, with regard to the use of WLM in poultry nutrition, it can be assumed that 10% addition is safe and does not affect performance.

Effects of legume-diet and sex of ducks on the growth performance, physicochemical traits of meat and fatty acid composition in fat

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.

Growth performance and Carcass quality in broiler chickens fed on legume seeds and rapeseed meal

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.

Quality and Physicochemical Traits of Carcasses and Meat from Geese Fed with Lupin-Rich Feed

Simple Summary

In the past, lupin seeds were not used in poultry feeding because of their alkaloid content, which affected the growth performance, producing negative results. Nowadays, new cultivars of lupins have reduced the anti-nutrition content and have been characterized by a high level of protein, similar to the level in soybean meal. Goose production is not popular and, generally, should be done by an extensive or semi-intensive system, which is corelated with small costs of feeds. Lupins can be used for crops where it is not possible to produce soybean (environmental conditions). Our study indicated that it is possible to produce goose meat with a good quality, where the feeding was based on various cultivars of lupins. Yellow, as well as white, lupin-rich feed had a positive effect on the meat traits and meat quality. Narrow-leaved lupin worsens the growth performance.

Abstract

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 Kołuda^® 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.

The Quality of Carcass and Meat from Geese Fed Diets with or without Soybean Meal

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 Kołuda^® 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.

The effect of faba bean extrusion on the growth performance, nutrient utilization, metabolizable energy, excretion of sialic acids and meat quality of broiler chickens

Soybean meal in broiler chicken diets can partly be replaced by faba bean seeds. Unfortunately, high levels of antinutritional factors and resistant starch found in these seeds can have a detrimental impact on both broiler chickens' performance and nutrient digestibility. It is, however, possible to increase the usefulness of faba bean for broiler nutrition by a technological process known as extrusion. In this study, the authors made and attempt to investigate the effect of different forms of faba bean seeds (raw or extruded) on broiler chicken performance, nitrogen-corrected apparent metabolizable energy values (AMEN), nutrient utilization and meat quality, as well as on the excretion of total and free sialic acids. In the trial, the total of 160 1-day-old male broiler chicks of the Ross 308 strain were used. Experimental birds were randomly assigned to two dietary treatments, each containing 10 replication (floor pens); one replication included nine birds. The first group contained 300 g/kg diet of raw faba bean seeds, whereas the second group - 300 g/kg diet of extruded faba bean seeds. The applied extrusion process was found to exert a positive impact and led to a decrease in phytic phosphorus, H, NDF, ADF and resistant starch content in studied faba bean seeds. Experimental birds fed diets containing extruded faba bean seeds were characterized by a lower feed intake (2299 g) and feed conversion ratios (FCRs) (1.52 g/g) in comparison with the other group (feed intake 2466 g; FCR 1.61 g/g). Extrusion of faba bean seeds improved dry matter retention, dietary AMEN value, apparent ileal digestibility of dry matter and starch, as well as most amino acids. In addition, the above-mentioned process resulted in a decrease in the excretion of total and free sialic acids. Extruded faba bean seeds failed to have a significant impact on broiler meat quality. It was concluded that application of extrusion can increase the use of faba bean seeds in broiler chicken nutrition.

Influence of graded levels of meals from three lupin species on growth performance and nutrient digestibility in broiler chickens

1. This study investigated the effect of different levels of seeds of lupin species (Lupinus angustifolius, Lupinus luteus and Lupinus albus) on broiler growth performance, nutrient digestibility and apparent metabolisable energy of poultry diets. 2. A control diet containing corn-soybean meal and test diets containing 50, 100, 150, 200 and 250 g/kg of three lupin species were fed to broiler chickens during a 35-day study period. There were 10 replicate cages of 8 broiler chickens per treatment. 3. Growth performance of the birds fed with yellow and white lupin diets was found to be similar to that of the birds in the control group. The use of narrow-leaved lupin seeds in the diet quadratically decreased the body weight gain of birds and increased feed conversion ratio during all the experimental periods (0-14, 15-35 and overall 0-35 days of age). 4. A significant interaction between lupin species and their inclusion levels for apparent metabolisable energy and apparent ileal digestibility of starch was observed, showing a negative effect of increasing levels of narrow-leaved lupin. Pearson correlation coefficients demonstrated that the presence of raffinose and non-starch polysaccharides is a key factor affecting the nutritive value of lupin, 5. Yellow and white lupins could be utilised as an alternative ingredient for soybean meal in the diet of broiler chickens without any adverse effects on growth performance. The narrow-leaved counterpart diet reduced broiler performance, and hence did not provide a satisfactory outcome.

Influence of graded inclusion of white lupin (Lupinus albus) meal on performance, nutrient digestibility and ileal viscosity of laying hens

1. The aim of this study was to investigate the effect of white lupin (Lupinus albus) meal (WLM) addition on the intestinal viscosity, bird performance and nutrient utilisation of laying hens. 2. The experiment was conducted with 360 laying hens aged 21 weeks fed one of 6 treatments, including a corn-soybean meal control diet (CON) and 5 experimental diets containing 60, 120, 180, 240 and 300 g/kg WLM. 3. A linear increase in feed intake (p < 0.001) was observed with higher levels of WLM from 0 to 300 g/kg. Laying rate decreased quadratically (p < 0.05) and egg weight (at 6th, 12th and 18th weeks of the trial) decreased linearly with WLM inclusion from 0 to 300 g/kg. Birds fed 60 g/kg or more of WLM laid lighter eggs (p < 0.05) than CON hens. When 240 g/kg or more WLM was included into the diet, laying rate was affected negatively (p < 0.05). 4. As WLM increased from 0 to 300 g/kg, apparent metabolisable energy and pre-caecal digestibility of dry matter and crude protein decreased quadratically (p < 0.05). When 300 g/kg of WLM was used, there was a tendency (p < 0.1) to decrease pre-caecal starch digestibility. WLM dose exerted a quadratic effect (p < 0.05) on total sialic acid excretion. As WLM increased, the viscosity of ileal digesta linearly increased (p < 0.05). 5. In the 6th and 12th weeks of the experiment (p < 0.05), eggshell thickness decreased linearly when 240 g/kg of WLM was added. At the 6th, 12th and 18th weeks, a linear decrease in eggshell content was observed (p < 0.05) after WLM addition. 6. In conclusion, the graded inclusion of WLM into laying hens' diets resulted in depressed performance, AME_N and eggshell quality.
