| Popis: | The aim of this research was to improve the quality of quails' eggs as well as the need of obtaining an appropriate ratio n-6/n-3 in the composition of this food. 192 quails (Coturnix coturnix japonica) were used, in posture, of 58 weeks of age. The experiment had the duration of 84 days (4 cycles of 21 days). The birds were distributed and four treatments were carried out in function of different percentage of linseed (T1 = 0 (it controls); T2 = 1.5; T3 = 3 and T4 = 5%), used together with the normal ration. Differences (P>0.05), were not found, in the cholesterol levels during the four treatments and among the cycles. Considering the poliunsatured fatty acids linoleic (LA, 18:2n-6), linolenic (LNA, 18:3n-3), arachidonic (AA, 20:4n-6) and the docosahexaenóic (DHA, 22:6n-3) comprising 15.28, 15.66 17.3 16.54% of total fatty acids, in relation to T1, T2, T3 and T4 respectively. There was a increase (P0,05), nos níveis de colesterol entre os quatro tratamentos e entre os ciclos. Dentre os ácidos graxos poliinsaturados destacaram-se o linoléico (LA, 18:2n-6), o linolênico (LNA, 18:3n-3), o araquidônico (AA, 20:4n-6) e o docosahexaenóico (DHA, 22:6n-3), perfazendo juntos 15,28, 15,66 17,3 16,54% do total de ácidos graxos, em relação a T1, T2, T3 e T4 respectivamente. Houve um aumento (P |
