- Abstract
This study was conducted to evaluate the effects of energy sources (broken rice and cassava) and standardized ileal digestibility sulfur amino acids to lysine ratio (SID SAA: Lys ratio) in diets on growth performance, nutrients digestibility and intestinal morphology of piglets. One hundred and twenty eight castrated male weaning pigs (Large White x Landrace x Duroc; initial BW, 6.67 ± 0.05 kg) were randomly divided into 8 treatments with 4 replications of 4 pigs. The experimental design was a 2 x 4 factorial treatment arrangement in Completely Randomized Design. Main effects were 2 energy sources (broken rice and cassava) and 4 ratios of SID SAA: Lys (45, 56, 64 and 72 percentage). Piglets fed with broken rice had higher ADG, ADFI and digestibility of DM and OM than those fed with cassava diet (P<0.01). Increasing SID SAA: Lys ratios linearly improved FCR (P=0.01). Consequently, to maintain the identical growth rate, dietary level of SID SAA: Lys ratio of piglets fed with cassava was higher than that of broken rice diet. Feeding cassava diet increased fiber intake, duodenal villous height and ileal crypt depth compare to the broken rice diet (P<0.05). The interaction effects of energy source and SAA: Lys ratio on intestinal morphology was found (P<0.05). High and low ratio of SID SAA: Lys in broken rice and cassava diets additionally increased duodenal villous height, respectively. Feeding piglets with broken rice resulted in higher growth rate and nutrients digestibility, lower SAA: Lys ratio requirement and shorter villous height than that of cassava diet. Morphological response seemed to be involved with synergic effects between fiber and SAA intake.
