Meat quality assessment from young goats fed for long periods with castor de-oiled cake.

ABSTRACT

Diet can influence both the qualitative and quantitative traits of ruminant meat. This study evaluated the effects of castor de-oiled cake on the meat of mixed-breed male goat kids. After 165days of diet treatment, no alterations (p>0.05) were observed in the in vivo performance, anatomic components, dissection and proximate composition of the Longissimus dorsi muscle, as well as in the color and pH of the carcasses. However, diet had an effect (p<0.05) on energy metabolites, fatty acid profile, and expression of certain proteins of the Longissimus dorsi muscle. To conclude, this study showed that the establishment of castor de-oiled cake diet for a long period to goats led to alterations in meat quality, without compromising its consumption qualities.
