Body yield and quality of fresh and post-freezing filet of Nile tilapia (Oreochromis niloticus) genetic groups.

The aim of this study was to evaluate the body yield and quality of fresh and post-freezing filet of male and female fish of inbred and non-inbred AquaAmérica genetic group and the hybrid between the AquaAmérica and Tilamax varieties. Forty fish (20 males and 20 females) of each genetic group were housed in four 48-m3 hapa net cages, getting 120 fish per cage. The fish were housed at 51 days of age and farmed for 269 days.

Effect of including oilseed grains in bovine diets on fatty acid profile, lipid stability, and sensory aspects of burgers.

The aim of this study was to evaluate the effect of including different oilseed grains in the diets of cattle on the qualitative and sensory characteristics and fatty acid profile of burger over a storage period of up to 120 days. The soybean diet increased 30% of ether extract in burgers when compared to the control diet. The inclusion of oilseeds in the bovine diet did not change the -6/-3 and hypocholesterolemic/hypercholesterolemic ratio, as well as the cholesterol levels in the burgers.
