    Background: previous studies have shown that fenugreek seed given at 6 g/hen/d in an attempt to reduce yolk cholesterol tended to reduce laying performance and that autoclaving and pre-germination improved its in vitro nutritional values. Objective: to evaluate the effect of dietary addition of unprocessed (UPFS), autoclaved (AFS) or pre-germinated (PGFS) fenugreek seeds on laying hens’ performance, egg physical characteristics and chemical composition. Methods: forty-eight 31 week-old Novogen white laying hens were divided into four groups and given 100 g/hen/d of a basal diet containing 0 (control) or 5.7 g of UPFS, AFS, or PGFS during nine weeks. Repeated and non-repeated data were analyzed using the Mixed and GLM procedures, respectively. Results: diet, week on diet and their interaction affected consumption (p0.05) by week on diet but was reduced (p0.05) by dietary treatment or by week on diet. Egg, yolk, albumen and shell weights were affected (p<0.05) by week on diet but not by diet nor diet-week interaction. Dietary inclusion of fenugreek seeds did not affect total egg crude protein, yolk lipids, and triglyceride nor yolk cholesterol contents. Conclusion: unprocessed fenugreek reduced laying rate and daily egg mass production, but these effects were removed by autoclaving or pre-germination. Further investigations are needed to evaluate the impact of fenugreek seeds dietary supplementation on fatty acids profile and lipid peroxidation

    Several investigations have suggested that fenugreek seeds may have a hypocholesterolemic activity, and thus be ecient in the treatment of egg yolk cholesterol. The objective of the current study was to evaluate the eect of dietary incorporation of 3% of fenugreek seed combined with 3% of linseed, 1% of garlic paste, and 0.078% of copper sulfate on laying performance, egg quality and lipids profile. Forty four, 41 weeks old, Novogen White laying hens received for 42 days 100 g/d of basal diet (control) or experimental diet (CFSGLSCS).With the exception of egg weight, which showed a significant increase for hens fed on CFSGLSCS with 57.99 g compared to 56.34 g for the control group, egg production (90.84% for control compared to 87.89% for experimental diet), egg mass (50.95 g/d for control compared to 50.87 g/d for CFSGLSCS), feed eciency (1.94 for control compared to 1.98 for CFSGLSCS) were not aected by dietary treatments. The addition of CFSGLSCS reduced (p < 0.05) egg yolk cholesterol by 5.4% and blood cholesterol from 158.42 mg/dL to 122.82 mg/dL for control and CFSGLSCS, respectively. The dietary addition of CFSGLSCS increased (p < 0.05) total lipids from 4.5 g/egg to 5.23 g/egg and didn’t aect (p > 0.05) yolk triglycerides

    Integration of trees with agricultural crops and livestock systems may offer advantages in term of productivity, economic return, and sustainability. In order to identify a candidate crop for Mediterranean silvoarable systems to be used in livestock farming as a protein source locally produced, a study was undertaken to evaluate the effect of feeding peas (Pisum sativum L.) as main protein source on milk yield and in vivo digestibility of primiparous buffaloes. Two almost isonitrogenous concentrates (on average, crude protein 240 g/kg dry matter) were formulated to contain, as fed basis, either 350 g/kg of soybean cake (SoyC) or 450 g/kg of extruded peas (PeaC) as the main protein source. Twenty primiparous buffaloes were blocked by age and body weight into two dietary treatments (Soyand Pea) from 10 to 100 day in milk. All cows were fed in the barn a total mixed ration containing 3 kg of SoyC and in the milking parlour they were individually supplemented by either 3 kg of SoyC or PeaC according to the group assignment. The substitution rate of soybean protein by pea protein was approximately 30%. Milk yield was not affected by the dietary use of extruded peas, as well as, milk fat and protein percentages, and clotting properties. Moreover, in vivo digestibility did not differ between the two dietary groups. Results support the partial substitution of soybean cake with extruded peas in diets for lactating buffaloe

    Several investigations have suggested that fenugreek seeds may have a hypocholesterolemic activity, and thus be efficient in the treatment of egg yolk cholesterol. The objective of the current study was to evaluate the effect of dietary incorporation of 3% of fenugreek seed combined with 3% of linseed, 1% of garlic paste, and 0.078% of copper sulfate on laying performance, egg quality and lipids profile. Forty four, 41 weeks old, Novogen White laying hens received for 42 days 100 g/d of basal diet (control) or experimental diet (CFSGLSCS). With the exception of egg weight, which showed a significant increase for hens fed on CFSGLSCS with 57.99 g compared to 56.34 g for the control group, egg production (90.84% for control compared to 87.89% for experimental diet), egg mass (50.95 g/d for control compared to 50.87 g/d for CFSGLSCS), feed efficiency (1.94 for control compared to 1.98 for CFSGLSCS) were not affected by dietary treatments. The addition of CFSGLSCS reduced (p &lt; 0.05) egg yolk cholesterol by 5.4% and blood cholesterol from 158.42 mg/dL to 122.82 mg/dL for control and CFSGLSCS, respectively. The dietary addition of CFSGLSCS increased (p &lt; 0.05) total lipids from 4.5 g/egg to 5.23 g/egg and didn&rsquo;t affect (p &gt; 0.05) yolk triglycerides

    The present study evaluated the effects of dietary supplementation of spirulina on laying hens&rsquo; performances: Eggs&rsquo; physical, chemical, and sensorial qualities. A total of 45 Lohman White hens, 44 weeks of age, were randomized into 3 groups of 15 birds. Hens were given 120 g/d of a basal diet containing 0% (control), 1.5%, and 2.5% of spirulina for 6 weeks. Albumen height and consequently Haugh unit were significantly affected by dietary supplementation of spirulina (p &lt; 0.05) and by weeks on diet (p &lt; 0.05). This supplement did not affect (p &gt; 0.05) egg yolk weight or height. However, spirulina increased egg yolk redness (a*) from 1.33 (C) to 12.67 (D1) and 16.19 (D2) and reduced (p &lt; 0.05) the yellowness (b*) parameter from 62.1(C) to 58.17 (D1) and 55.87 (D2). Egg yolks from hens fed spirulina were darker, more red, and less yellow in color than egg yolks from hens fed the control-diet (p &lt; 0.0001). However, spirulina did not affect (p &gt; 0.05) egg yolks&rsquo; total cholesterol concentration. In conclusion, a significant enhancement of egg yolk color was found in response to spirulina supplementation. Further investigations are needed to evaluate the impact of spirulina on egg yolks&rsquo; fatty acids profile

    Abstract Background: previous studies have shown that fenugreek seed given at 6 g/hen/d in an attempt to reduce yolk cholesterol tended to reduce laying performance and that autoclaving and pre-germination improved its in vitro nutritional values. Objective: to evaluate the effect of dietary addition of unprocessed (UPFS), autoclaved (AFS) or pre-germinated (PGFS) fenugreek seeds on laying hens’ performance, egg physical characteristics and chemical composition. Methods: forty-eight 31 week-old Novogen white laying hens were divided into four groups and given 100 g/hen/d of a basal diet containing 0 (control) or 5.7 g of UPFS, AFS, or PGFS during nine weeks. Repeated and non-repeated data were analyzed using the Mixed and GLM procedures, respectively. Results: diet, week on diet and their interaction affected consumption (p0.05) by week on diet but was reduced (p0.05) by dietary treatment or by week on diet. Egg, yolk, albumen and shell weights were affected (p0,05) por semana na dieta, mas foi reduzida (p0,05) nem pela dieta nem pela semana na dieta. Os pesos do ovo, da gema, da albumina e da casca foram afetados (p0,05) o conteúdo de proteína bruta total dos ovos, dos lipídios, triglicérides nem do conteúdo de colesterol da gema. Conclusão: sementes de feno-grego não tratadas reduziu a taxa de postura e a produção diária de massa de ovos, mas estes efeitos foram removidos pela autoclavagem e pré-germinação. São necessárias novas investigações para avaliar o impacto da suplementação alimentar sobre a semente de feno-grego no perfil de ácidos graxos e peroxidação lipídica.Resumen Antecedentes: estudios anteriores sugirieron que el suministro de 6 g/gallina/día de semillas de alholva utilizadas con el fin de bajar el contenido en colesterol en la yema, tendió a reducir el rendimiento en gallinas ponedoras y que el tratamiento en autoclave y la pre-germinación mejoraron su valor nutritivo in vitro. Objetivo: evaluar los efectos de la adición de semillas de alholva no tratadas (UPFS), tratadas en autoclave (AFS) o pregerminadas (PGFS) en dietas de gallinas ponedoras sobre la producción, la composición química y la calidad física del huevo. Métodos: cuarenta y ocho gallinas ponedoras blancas de 31 semanas de edad de la línea Novogen white fueron divididas en cuatro grupos, a las cuales se les suministró 100 g/gallina/día de una dieta base que contenía 0 (control) o 5,7 g de UPFS, AFS o PGFS durante nueve semanas. Los datos con o sin repeticiones fueron analizados mediante los modelos mixtos y GLM, respectivamente. Resultados: la dieta, la semana en la dieta y su interacción afectaron el consumo (p0,05) por la semana en las dietas, sin embargo, fue reducida (p0,05) ni por la dieta ni por la semana en la dieta. Los pesos del huevo, de la yema, de la albúmina y de la cáscara fueron afectados (p<0,05) por la semana en la dieta, pero no por la dieta ni su interacción. La inclusión de semillas del alholva en la dieta no influyó (p<0,05) en la concentración total de proteína bruta del huevo, de lípidos, triglicéridos ni en los contenidos de colesterol en la yema. Conclusión: las semillas de alholva no tratadas redujeron el porcentaje de puesta y la producción diaria de masa de huevo, pero estos efectos fueron removidos por el autoclavado o la pregerminación. Se necesitan más investigaciones para evaluar el impacto de la incorporación dietética de las semillas de la alholva sobre el perfil de los ácidos grasos y la peroxidación lipídica

    This study evaluated the effect of dietary incorporation of linseed alone or along with dried tomato paste-pepper powder mix on egg physical characteristics, antioxidant profiles, lipid oxidative status, and yolk coloration before and after storage at 4 &deg;C for one month. Sixty Novogen White laying hens, 27 weeks-old, were divided into three groups and given 100 g/hen/day of a standard diet (C), standard diet containing 4.5% of ground linseed (L), linseed diet containing 1% of dried tomato paste and 1% of sweet red pepper (LTP). Linseeds increased (p &lt; 0.05) egg yolk antioxidant capacity but not lipid oxidative stability (p &gt; 0.05). However, dietary inclusion of LTP did not improve fresh egg yolk antioxidant activity and lipid oxidation stability (p &gt; 0.05). With reference to the stored eggs, only antioxidant activity measured by phosphomolybdenum reduction and lipid oxidative stability were influenced (p &lt; 0.05) by the dietary treatment. Fresh egg yolk of hens fed on linseeds tended to have a slightly more yellow, redder, and less light color than the eggs of hens fed with the control diet. Dietary supplementation of LTP increased (p &lt; 0.05) the Roche yolk color fan (RYCF) score and redness (a*) and decreased (p &lt; 0.05) lightness (L*) without affecting (p &gt; 0.05) saturation (C*). Storage of hens&rsquo; eggs fed on the control diet did not influence (p &gt; 0.05) yolk color

    This study evaluated the effect of linseed incorporation in laying hens&#8217; feed (alone or along with a tomato-red pepper mix) on laying hens&#8217; egg yolk fatty acids profile, as well as on their atherogenic (IA) and thrombogenic (IT) health lipid indexes, and the ratio between the hypocholesterolemic and hypercholesterolemic fatty acids (HH). Sixty 27 weeks-old Novogen White laying hens were divided into three groups and given 100 g/hen/day of a standard diet (Control, C) containing 4.5% of ground linseed (Linseed diet, L), containing 1% of dried tomato paste and 1% sweet red pepper (Lineseeds-Tomato-Pepper, LTP). The linseed dietary inclusion significantly reduced the egg yolk content of palmitic acid from 25.41% (C) to 23.43% (L) and that of stearic acid from 14.75% (C) to 12.52% (L). Feeding 4.5% ground linseed did not affect the egg yolk content of &#945;-Linolenic acid but significantly increased the egg yolk concentration of eicosapentaenoic acid (EPA) from 0.011% (C) to 0.047% (L) and that of docosahexaenoic acid (DHA) from 1.94% (C) to 2.73% (L). The IA and the HH were not affected (p &gt; 0.05) by the dietary addition of linseed, whereas the IT decreased (p &lt; 0.05) from 1.16 (C) to 0.86 (L). Adding tomato-sweet red pepper mix to the linseed-supplemented feed did not affect the measured parameters as compared to the linseed dietary treatment
