Apparent Digestibility Coefficients and Serum Biochemical Parameters in Growing-Fattening Pigs Fed with Different Dietary Sources and Levels of Crude Fiber with Additional Pro/Prebiotics

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
