Abstract
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.

Abstract
SCOPE Habitual diet may be reflected in metabolite profiles that can improve accurate assessment of dietary exposure and further enhance our understanding of their link to health conditions. We aimed to explore the relationship of habitual food intake with blood and urine metabolites in adolescents and young adults. METHODS The study population comprised 228 participants (94 male and 134 female) of the DONALD study. Dietary intake was assessed by yearly repeated 3d-food records. Habitual diet was estimated as the average consumption of 23 food groups in adolescence. Using an untargeted metabolomics approach, we quantified 2638 metabolites in plasma and 1407 metabolites in urine. In each sex, we determined unique diet-metabolite associations using orthogonal projection to latent structures (oPLS) and random forests (RF). RESULTS We observed 6 metabolites in agreement between oPLS and RF in urine, 1 in females (vanillylmandelate to processed/ other meat) and 5 in males (indole-3-acetamide, and N6-methyladenosine to eggs; hippurate, citraconate/glutaconate, and X - 12111 to vegetables). We observed no association in blood in agreement. CONCLUSION We observed a limited reflection of habitual food group intake by single metabolites in urine and not in blood. The explored biomarkers should be confirmed in additional studies. This article is protected by copyright. All rights reserved.

Abstract
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.

Abstract
The present study aimed to evaluate the effects of dietary substitution of soybean meal (SBM) with micronized-dehulled white lupin (Lupinus albus L. cv. Multitalia) in guinea fowl broilers on their growth performance, carcass traits, and meat fatty acids composition. A total of 120 one-day-old guinea fowl females were randomly assigned to 2 treatments which were fed from hatch to 12 wk of age. Birds were fed 2 wheat middlings-based diets comprising of a control treatment which contained SBM (195 g/kg) and a test diet containing micronized-dehulled lupin (240 g/kg) as the main protein source. Replacing SBM with treated lupin had no adverse effect on growth traits, dressing percentage, or breast and thigh muscles relative to the weight of guinea fowls. A decrease (P < 0.05) of abdominal fat was found in guinea fowls fed lupin-diet. Breast muscle from birds fed lupin had higher lightness (L*) (P < 0.01) and redness (a*) (P < 0.05) scores and water-holding capacity (P < 0.05) than the SBM-control diet. Meat from guinea fowls fed lupin had less total lipids (P < 0.05) and cholesterol (P < 0.01), and higher concentrations of phospholipids (P < 0.01). Feeding treated lupin increased polyunsaturated fatty acid (PUFA) levels in breast meat and decreased saturated fatty acid (SFA) concentrations. Our findings suggest that replacing SBM as protein source with micronized-dehulled lupin in meat-type guinea fowl diet can improve carcass qualitative characteristics, enhancing also meat lipid profile with no effect on growth traits.

Abstract
This study was conducted to evaluate the effect of substitution of soybean meal (SBM) with dehulled-micronized peas (Pisum sativum) in diets of guinea fowl broilers on their growth performance, carcass yields, and fatty acid composition of meat. One hundred forty 1-d-old guinea fowl keets were randomly assigned to 2 dietary treatments, which were fed from hatch to 12 wk. The birds were fed 2 wheat middling-based diets comprising a control diet, which contained SBM (78 g/kg) and a test diet containing dehulled-micronized peas (180 g/kg) as the main protein source. The substitution of SBM with peas had no adverse effect on growth performance, dressing percentage, or breast and thigh muscle relative weights of the guinea broilers. However, a reduction of abdominal fat content (P < 0.05) was observed in birds fed the pea diet compared with the control. Breast and thigh meat of birds fed the pea diet had higher lightness scores (P < 0.05) and water-holding capacity (P < 0.01) than the control. Meat from guinea fowls fed the pea diet had less cholesterol (P < 0.01) and lipids (P < 0.05), and higher concentrations of phospholipids (P < 0.05). Feeding peas increased polyunsaturated fatty acid concentration in breast and thigh muscles, and decreased the saturated fatty acid concentration. Feeding the pea diet also lowered the n-6/n-3 polyunsaturated fatty acid ratio of the guinea broiler muscles. Our results suggest that replacing the conventional SBM as the protein source with dehulled-micronized pea meal in diets of guinea fowls broilers can improve carcass quality and favorable lipid profile without adversely affecting growth performance traits.

Abstract
BACKGROUND A study was carried out to compare the effect of diets containing micronised-dehulled lupin (Lupinus albus L. cv. Multitalia) on growth performance, carcass yields and meat fatty acid profile of broiler chickens. RESULTS Hubbard strain chicks receiving from 14 d to slaughtering age (49 d) a wheat middlings-based diet containing either deffatted soybean meal (195 g kg(-1), control) or dehulled micromicronised lupins (240 g kg(-1)) as the main protein source were used. The inclusion of treated lupin meal in the diet did not result in lower growth rates of chicks. Lupin diet had no effect on dressing percentage, or breast and drumstick muscles relative weights, but a reduction of abdominal fat content was reported (P < 0.05). White and dark meats of birds fed lupin diet had significant (P < 0.05) lower L* (lightness) values and fat content (P < 0.05). Total collagen and water-holding capacity values were higher in lupin treatment. Feeding the lupin diet resulted in lower saturated fatty acid content in breast and drumstick meat, as well as the n-6/n-3 polyunsaturated fatty acid (PUFA) ratio and saturation, atherogenic and thrombogenic indexes, while total PUFA and monounsaturated fatty acids levels increased (P < 0.05). CONCLUSION These results suggest that replacing soybean meal with dehulled-micronised lupin meal in diet for broiler chickens can produce meat with favourable lipid profile and quality, with no adverse effects on productive parameters.

Abstract
The objective of this study was to determine the effect of dietary dehulled-micronized fava bean (Vicia faba var. minor) seed on egg production, egg weight, feed conversion ratio, eggshell quality, and egg yolk color. In this trial, 18-wk-old laying hens in the early phase of production (ISA Brown) were randomly assigned to 2 groups and fed durum wheat middlings-based diets containing soybean or micronized-dehulled fava bean meal as the main protein source. Eggs were collected and weighed daily. Laying performance, egg quality, and feed conversion ratio were evaluated for 10 wk. The only significant effect detected was for feed intake (P<0.05), which was lower in hens fed the diet containing fava bean than for hens fed soybean meal, without however any negative effects on feed efficiency. None of the egg quality parameters studied were influenced by dietary treatment, except for yolk color score that was reduced in hens fed the fava bean diet (P<0.05). We conclude that dehulled-micronized fava beans in the diet did not have a negative influence on productive performance or egg quality of young brown hens.

Abstract
An experiment was carried out to evaluate the effects of diets containing peas on productive traits, carcass yields, and fatty acid profiles (breast and drumstick meat) of broiler chickens. Hubbard strain broiler chicks, divided into 2 groups, received from 14 d to slaughtering age (49 d) a wheat middlings-based diet containing soybean (190 g/kg) or micronized-dehulled peas (400 g/kg) as the main protein source. The inclusion of peas did not significantly change the growth performance of birds. The pea level had no effect on the dressing percentage, the percentage of breast or drumstick muscles, and abdominal fat. The muscles of birds fed the pea diet had significant (P < 0.05) lower L* (lightness) and b* (yellowness, drumstick muscle) values and fat content. Instead, total collagen and water-holding capacity values were higher in the pea treatment. The polyunsaturated fatty acid concentration in breast and drumstick muscles was significantly increased with the alternative protein source inclusion, whereas the saturated fatty acid was similar among treatments. The n-6/n-3 polyunsaturated fatty acid ratio of the broiler drumstick meat decreased significantly in the pea group. Dietary pea inclusion improved the saturation index of meat without altering atherogenic and thrombogenic indexes. It can be concluded that the pea treatment tested had a positive effect on the performance and meat quality of broiler chickens.

Abstract
Different livestock feeds manipulations have been reported to reduce the total P concentration in manure. Information on the influence of these dietary manipulation strategies on the forms of P in manure is, however, limited. This study was, therefore, conducted to investigate the effect of diet manipulation through feed micronization and enzyme supplementation on the forms of P in swine manure. Eight growing pigs were fed four diets: barley-raw pea (BRP), barley-micronized pea (BMP), barley-raw pea with enzyme (BRPE), and barley-micronized pea with enzyme (BMPE) in a 4 x 4 Latin square design. Because we are interested in the effect of enzyme cocktail and pea micronization on manure P, we did not reduce the non-phytate P with enzyme addition in this study. The fecal material and urine were collected and analyzed for total P. Fecal material was fractionated to determine the total P in H2O-, NaHCO3-, NaOH-, and HCl-extractable fractions. The total P in the residual fractions was also determined. About 98% of the total P excreted by the pigs was found in the fecal material. Inclusion of micronized pea in pig diet did not have any significant effect (p > 0.1) on either the total P or the different P fractions in the manure. The labile P (the sum of H2O-P and NaHCO3-P) was significantly reduced (p < 0.05) by the addition of enzyme to swine diets. Pigs fed the BRPE and BMPE had 14 and 18% lower labile P, respectively, compared with pigs fed the BRP. Enzyme addition to pig diets reduced not only the total P in manure, but also the labile P fraction, which is of great environmental concern. Thus, the potential of P loss to runoff and the subsequent eutrophication can be reduced by enzyme addition to pig diets.

Abstract
1. A 70-d experiment was conducted to determine the response of 26-week-old laying pullets to cereal-free diets based on maize offal, cassava peel and full-fat cashew nut meal (CNM) in comparison with a standard 550 g maize/kg reference diet. The 4 test diets all contained 315 g CNM/kg 232.5, 155.0, 77.5 and 0.0 g/kg of maize offal in combination with 77.5, 155.0, 232.5 and 315.0 g/kg of cassava peel, respectively. 2. Pullets fed on the 4 CNM-based diets consumed (P<0.05) less food than those fed on the reference diet; they also had lower (P<0.05) rates of lay, produced less (P<0.05) egg mass, had lower (P<0.05) food conversion efficiencies and their eggs had a lighter (P<0.05) yolk colour. Pullets fed some of the CNM-based diets also gained more (P<0.05) weight, the heaviest (P<0.05) being birds reared on the diet containing 315 g/kg cassava peel. Egg weight, shell thickness and albumen height from all eggs were similar. Pullets fed on the CNM-based diets had inferior (P<0.05) retention of dry matter and protein. 4. It was concluded that feeding full-fat CNM allowed for high dietary inclusion rates of cassava peel and maize offal and the resultant diets, which contained no maize, supported satisfactory performance of laying hens.
