RESUMO
This study measured the effect of replacing dietary fat from an animal source with palm oil supplements on the intramuscular fatty acid profile and sensory quality traits of the meat from young bulls. Thirty-six entire male Friesian calves (mean age=6.8±1.1 months, mean live weight=162.5±28.6kg) were assigned to one of four isoenergetic (1.03 MFU/kg DM) and isoproteinic (15.5% CP) diets, that differed in their fat additives: (D1) lard-tallow mix (control); (D2) hydrogenated palm oil fatty acids (PFA); (D3) calcium salt of partially hydrogenated PFA, and (D4) calcium salt of the fatty acid distillate from palm oil. Bulls (mean live weight=391.3±30.3kg) were slaughtered under commercial conditions and sensory tests were performed to evaluate the effects of the four diets and ageing time (1, 10, and 21d). Only the proportions of C16:0 and C18:0 were significantly affected by the palm oil dietary supplement. Ageing time affected grass odour, tenderness, juiciness, fibrosity, liver flavour, and acid flavour. Nevertheless, palm oil supplements did not negatively alter the organoleptic characteristics of the meat.
RESUMO
The authors report a case of Abrikossof's tumor that came under their observation. The reappraisal of the literature permits to review on this disorder that was unknown until few years ago. Electronic microscope and immunohistochemical study allowed to recognize the real origin of this tumor. It arises from peripheric nervous tissue particularly from Schwann's cells. This neoplasm must be considered as benign, especially when of small dimensions. In case of rapidly growing or larger than 8 cm forms a widely exeretic surgery and a careful follow-up, because of the possibility of finding tumors in other district of the body.
