          Abstract

          ABSTRACT Amaranth (Amaranthus cruentus L.) is a food high in protein and lysine content, and has a well-balanced amino acid composition. In addition, it has shown to be efficient in lowering egg cholesterol. The objective of this study was to evaluate the effect of different inclusion levels of Amaranthus cruentus L. in the diet of laying hens, on egg cholesterol content and production parameters. 200 laying hens of 30 weeks of age were fed on diets that included 0, 15, 30 and 45% (dry matter basis) of A. cruentus. For 2 months, weekly feed intake per hen, egg production per week, egg mass and feed conversion ratio were evaluated. 480 eggs were analyzed to determine cholesterol content by high performance liquid chromatography. The results were analyzed by analysis of variance for a randomized block design. The inclusion of 15% of A. cruentus seeds in the diet decreased egg yolk cholesterol content without significantly affecting the main production parameters.

          RESUMEN El amaranto (Amaranthus cruentus L.) es un alimento de alto aporte en proteína, lisina y buen balance de aminoácidos. Además, ha demostrado ser eficiente para disminuir el colesterol del huevo. El objetivo de este estudio fue evaluar el efecto de diferentes niveles de inclusión de A. cruentus L. en la dieta de aves de postura, sobre el contenido de colesterol en el huevo y parámetros productivos. Se realizó un experimento con 200 gallinas Hy Line de postura de 30 semanas de vida, para evaluar la inclusión de A. cruentus en proporciones de 0, 15, 30 y 45% base materia seca. Durante 2 meses se evaluó el consumo semanal de alimento por ave, producción de huevos por semana, masa de huevo y conversión de alimento; 480 huevos fueron analizados para determinar el contenido de colesterol mediante cromatografía liquida de alto rendimiento. Los resultados fueron analizados mediante análisis de varianza en diseño de bloques al azar. La inclusión de semillas de A. cruentus en 15% de la ración disminuyó el colesterol en la yema de huevos, sin afectar significativamente los principales parámetros productivos.

            Black cumin (Nigella sativa L.) supplementation into the diet of the laying hen positively influences egg yield parameters, shell quality, and decreases egg cholesterol.

            The objective of this study was to determine the effects of various levels of dietary black cumin seed on egg production, egg weight, feed conversion ratio, egg shell quality, and egg yolk cholesterol. In this study, eighty 27-wk-old laying hens (Hyline-5 White) were randomly assigned into 4 groups with 4 replicates of 5 birds each (20 laying hens per group) and fed diets supplemented with 1, 2, or 3% black cumin. Eggs were collected and weighed daily. Laying performance, egg quality, and feed conversion ratio were evaluated. Laying hens fed the diet supplemented with 3% black cumin had greater egg production than the control. Diets supplemented with 2 or 3% black cumin increased egg weight compared with other groups. Yolk weights of the eggs from hens fed diets containing 1, 2, and 3% black cumin were significantly greater than those from the control group. Shell thickness of the eggs from chickens fed 2 or 3% black cumin seed was significantly greater than those from chickens fed diets supplemented with 0 or 1% black cumin seed. Also, shell strength of the eggs from hens fed diets supplemented with 3% black cumin seed was significantly greater than the control. In addition, diets supplemented with 2 or 3% black cumin significantly decreased egg cholesterol per gram of yolk compared. No level of black cumin seed supplementation had any effect on live weight, feed consumption, feed conversion ratio, organ weights, and abdominal adipose tissue. This study showed that black cumin at the level of 2 or 3% would positively influence egg production, egg weight, and shell quality and decrease the concentration of cholesterol in the egg yolk.
