Abstract

The objective of this study was to increased breeding area in same size pig pen and growth performance of weaning pigs. A total of 330 crossbred ($6.68{\pm}0.36kg$) weaning pigs were subjected to a 42-day feeding trial(3 pens/treatment) in which effects of the semi-floor were compared : NC; Negative control ($0.23m^2/pig$; 40 pigs/pen), PC; Positive control($0.30m^2/pig$; 30 pigs/pen) and Semi-floor($0.30m^2/pig$; 40 pigs/pen). There was a significant effect on BW at 6 week along all treatment(P<0.01). There was a effect of Semi-floor treatment on ADG(average daily gain) only during the first 3 week after weaning(P<0.01). No significant effect was observed in the ADFI during the experiment period. NC treatment had significantly lower BUN value than other treatments(P<0.05). The results from immune and stress response with semi-floor suggest that no negative effects in their blood analysis. Consequently, semi floor treatments increased additional breeding area and also growth performance rather than other treatments in weaning pigs.
