The study investigated the effect of different fiber levels and sources on the blood profile and digestibility coefficients parameters. Compared to C diet that contained 3.5% crude fiber (CF), the feed formulation has takeninto consideration a level of 6.5% CF on E1 group and 7.5% CF on E2 group provided by adding alfalfa meal and sunflower meal. The experiment was conducted on 9 pigs randomly assigned to 3 experimental groups for 8 weeks trial period with an initial average weight of 25 kg. During the balance period, average samples of faeces/pig were collected to determine the apparent digestibility coefficients; blood samples were collected by jugular venipuncture in heparin tubes and centrifuged (3000 rpm for 15 min) for plasma separation. The highest values were registered for serum creatinine (SCR) parameter for group E1 group compared to C and E2 groups, and also, high levels of lactat dehydrogenase (LDH) were observed on E1 group was significantly different (P

The highest values were registered for serum creatinine (SCR) parameter for group E1 group compared to C and E2 groups, and also, high levels of lactat dehydrogenase (LDH) were observed on E1 group was significantly different (P<0.05) compared to C and E2 groups.Biochemical serum parameters LDH and SCR are important indicators to evaluate animal health and although we observed higher values for E1, there were within species limits. The different levels and sources of fiber content of feeding formula did not affect the apparent digestibility coefficients, nor the blood parameters. [ABSTRACT FROM AUTHOR]
