dc.description.abstract | Abstract: An experiment was conducted to examine the effects of exogenous enzyme complex (FarmzymeⓇ) supplementation on growth performance, nutrient digestibility, pork quality, blood profiles and economical analysis in growing-finishing pigs. A total of 80 growing pigs ([Yorkshire × Landrace] × Duroc), averaging 28.9 ± 0.04 kg body weight, were allotted to 1 of 4 treatments based upon body weight and sex in a randomized complete block (RCB) design in 5 replicates with 4 pigs per pen. Treatments were divided by exogenous enzyme (FarmzymeⓇ) levels (0, 0.05, 0.1 or 0.15%) and corn-SMB basal diet was regarded as control treatment. Four phase feeding programs were used for 12 wk of whole experimental period | - |
dc.description.abstract | early growing (0-3 week), late growing (4-6 week), early finishing (7-9 week) and late finishing (10-12 week). During the whole experimental period, body weight, ADG and G:F were increased by addition of exogenous enzyme complex in diet (linear, P=0.02, P=0.02, P<0.01, respectively) while, ADFI was reduced with exogenous enzyme complex supplementation (linear, P=0.09,). In nutrient digestibility of growing pigs, crude fat and protein digestibilities were increased by exogenous enzymes complex in the diet (linear P=0.05, P=0.10 respectively). There were no significant differences in the blood urea nitrogen (BUN), but blood glucose increased significantly in late growing phase (quadratic, P<0.01). In pork quality, there were no significant differences although some values were varied. When exogenous enzyme complex was supplementedn in diet, days to reach 115kg market weight was shortened and cost of feed was cheaper than control treatment. Consequently, when pigs were fed diets with high level of exogenous enzyme complex (FarmzymeⓇ), a better growth performance was observed in growing-finishing period and was higher when 0.15% of exogenous enzyme complex was provided.
