Adición de ácidos grasos omega tres en la carne de pollo con aceite de atún

Abstract

Abstract. This research was carry out with the purpose to adittion at broiler meat, breast and legs-thighs muscles, fatty acids 3 (n-3) with tuna oil (TO). Two hundred ten broiler chickens Ross x Ross from 0 to 52 days old, were carried out in five treatments with three replicates of fourteen broilers without sex; replace soybean oil by TO, 0, 0.75, 1.5, 2.25 and 3.0% levels, in sorghum base diets + soybean meal. There were not difference (P>0.05) in feed consumption, body weight gain was less (P 0.05) with 0.75 and 3 % of TO, feed conversion was less (P 0.05) with 1.5 % of TO. Total lipids (TL) of breast, were similar (P>0.05), to n-6, linoleic less (P 0.05) and arachidonic less with 2.25 %, to n-3, linolenic less (P 0.05) eicosapenthaenoic (EPA) and docosahexaenoic (DHA) increased (P 0.05) with TO levels. Legs-thighs muscles TL, were not difference (P>0.05), to n-6, linoleic less (P 0.05) similar arachidonic with 1.5 % to increase TO level, EPA and DHA increased (P 0.05) with TO level. The conclusion that TO did not affect feed consumption, less body weight gain, broiler meat less n-6, increased n-3 EPA and DHA, and it is an alternative source of n-3 as ingredient to broiler diets.
