title: Nutritionally related blood metabolites and performance of finishing pigs fed on graded levels of dietary fibre.
abstract: The objective of the study was to determine effect of feeding fibrous diets on performance and biochemical profiles of finishing pigs. A total of 84 clinically healthy male pigs were used in the experiment. Body weight of the pigs at the beginning of the experiment was 85 ± 10.1 kg. Maize cob (MC), sunflower hulls (SH), lucerne hay (LH) and dried citrus pulp (PU) were incorporated in a basal diet for finishing pigs at different inclusion levels of 0, 80, 160, 240, 320 and 400 g/kg. Effects of week of feeding, fibre source and inclusion level of fibre were significant (P < 0.05). Pigs consumed more LH compared to MC, SH and PU. Average daily gain was high for pigs consuming diets with inclusion levels of 0, 80, 160 and 240 g/kg and low for pigs consuming 320 and 400 g/kg inclusion level of fibre in a diet. There was an increase in serum total concentration (TP) with an increase in PU, MC and LH in pig diets (P < 0.05). Creatine kinase (CK) concentrations decreased as levels of PU, LH and MC increased (P < 0.05). Increasing inclusion level of LH and SH in pig diets resulted in an increase in glycated haemoglobin concentration (P < 0.05). It can be concluded that level of PU, LH, MC and SH in diets of finishing pigs negatively influences average daily feed intake, average daily gain and biochemical profiles.
