Fontes de lipídeos associados à palma forrageira sobre as características sensoriais da carne ovina.

Abstract

The search for food that meets commercial and healthier requirements has created a greater search for meat of higher quality and nutritional value. In this paper, the goal was to evaluate the effect of diets with different lipid sources associated with forage palm on the sensory characteristics of sheep meat. The research included 39 male animals, without a defined racial pattern, castrated, 4 months old and an average initial weight of 22 kg. The experiment took place in the Department of Animal Science, sheep and goat farming sector of the Universidade Federal Rural de Pernambuco, located in Recife, Pernambuco. The treatments consisted of Tifton Hay and Forage Palm as forage, and ground corn, wheat bran and mineral salt as concentrate. In the experimental diet, cottonseed, corn germ and coconut cake were inserted in the concentrated feed. The animals were housed in individual suspended stalls, containing feeders and drinkers, distributed in a covered shed. The experiment lasted 60 days, with the first 30 days aimed at adapting the animals to diets, facilities and management. The last 30 days were devoted to data collection and evaluations. From the Longissimus lumborum muscle, the characteristics, sensory attributes and commercial value of sheep meat were evaluated. The diets utilized with lipid sources did not show significant differences in the sensory characteristics of sheep meat (P>0.05), showing a positive positioning of the evaluators regarding purchase intention, which makes it a good alternative for lambs in the termination phase.
