Descripción
El presente estudio se realizó con el fin de enriquecer los huevos de gallina con ácidos grasos omega 3 a partir de la inclusión de semilla de lino en la dieta. Se incluyeron niveles de 0 (T4), 10 (T1), 15 (T2) y 20 (T3) % de linaza, se determinó la composición de ácidos grasos por cromatografía de gases, se evaluó la producción y calidad del huevo. El porcentaje de producción de huevo fue superior en los grupos T4 y T2 (p>0.05) con 93,0 y 91,5 % de producción con respecto a 86,0% de los grupos T1 y T3. La mejor conversión de alimento se presentó en los grupos T4 y T2. Con la inclusión de semilla de lino se incrementó el contenido de ácidos grasos n-3 de 3,0 % del grupo T4 a 12.6 % en el grupo T3, siendo los ácidos α-linolenico (C18:3n-3) y DHA (C22:6 n-3) los más importantes de esta serie. Con la inclusión de linaza en la dieta de las gallinas ponedoras se redujo el contenido de ácido linoléico (C18:2n-6) y con esto la relación entre ácidos grasos n-6: n-3. Con base en la evaluación económica se concluye que es viable enriquecer la yema de huevo de gallina hasta un 10.1 % de ácidos grasos n-3 con 15 % de inclusión de linaza y un sobre costo de 8.04%/huevo.
The current research was carried out in order to enrich the hen’s eggs with Omega 3 fatty acids from the inclusion of flax in its diet. 0 (T4), 10 (T1), 15 (T2) and 20 (T3) linseed levels were included; the fatty acids composition was determined by a Gas Chromatography; and the egg’s production and quality were evaluated. The egg’s production percentage, 93, 0 and 91.5%, in the T4 and T2 (P>0.05) group was upper than the T4 and T2 groups percentage, 86.6%. The best food conversion was presented in the T4 and T2 groups. The 3.0% of n-3 fatty acids content was increased from the T4 group at 12.6% to the T3 group whit the flax seed inclusion; where the α-linolenic (C18:3 n-3) and DHA (C22:6) acids were the most important ones of this series. The linolenic acid (C18:2 n-6) along with the relation between fatty acids n-6:n-3 were reduced with the inclusion of linseed in the layer’s diet. Based on the economic evaluation, it could be concluded that it is feasible to enrich the egg yolk to a 10.1% of n-3 fatty acids with 15% linseed inclusion and a cot overrun of 8.04% per egg.
