Description
  • Effect of age on apparent digestibility of fatty acids was investigated from the 2nd till the 42nd day using Ross chickens fed ad libitum by a commercial feed mixture. Digestibility of all fatty acids rapidly decreased from Day 2 to Day 4. This drop was followed by an increase till Day 8. Observed changes is possible to explain on the basis of excretion of endogenous nutrients originating primarily from the yolk sac.Within the period of Days 9 to 42, coefficients of all saturated and monounsaturatedfatty acids (with exception of C20:1 n-9) significantly (P<0.001) decreased with age. Changes in digestibility of linoleic, a-linolenic, arachidonic, and docosahexaenoic acid were very small (P>0.05). Digestibility of eicosapentaenoic acid increased highly significantly; the daily increase was 1.09 per cent. Mean value of polyunsaturated fatty acids digestibility was higher (P<0.001) than those of saturated and monounsaturated fatty acids.
