Abstract
A total of 30 rabbits , bearing to 4 experimental goups were slaughtered then sectioned; after a period of deep freezing, the same cut was boiled or roasted. Roasted-meat, boiled -meat and boiling-water-extract was tested by a panel of 9 different aged-judges. Experimental thesis were: M, control, fed commercial diet alone; P, fed commercial diet + pelletted alfalfa-hay; PI, fed commercial diet + pelletted alfalfa -hay with vitamin-mineral premix; F, fed commercial pellet + alfalfa-hay cut 8-10 cm long. Every judge had to discover differences between each couple of sampl e of meat or water-extract in the orthogonal tests with the hidden controls. Results showed that ability to particularize samples depends on individual competence; no relatioship was detected between judges'age and ability; replicate- effect (timr of judgement) was highly significant, rabbits fed with the cut hay added to the commercial pellet were different from the others groups in higher percentage but, statistical differences were reached only between thesis Fvs M in roasted meat, and F vs P in boiled meat. The absence of difference between Pi, P and M suggested that the observed alfalfa effect gained subsistence only if the hay is not milled then pelletted.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
