Abstract

A study was conducted to determine the ileal digestibility (ID) of amino acids and feeding values of spray dried plasma protein (SDPP) and spray dried porcine intestine hydrolysate (SDPI) in early-weaned pigs. Twelve pigs aged 18 days old (Landrace${\times}$Yorkshire${\times}$Duroc; $5.83{\pm}0.51kg$ BW) were cannulated in the terminal ileum for determination of ID of amino acids. Ninety pigs ($6.28{\pm}0.1kg$, 18 days old) were also employed for a feeding trial during phase I period. Treatments were: 1) 6% SDPP, 2) 6% SDPI, and 3) 3% SDPP+3% SDPI. The apparent and true ID values of the essential amino acids except leucine, methionine and valine were lower (p<0.01) in SDPI than in SDPP. The average apparent ID of essential amino acids in SDPP and SDPI were 75.63 and 71.30%, and the average true ID of essential amino acids 84.83 and 80.51%, respectively. The ADG and feed conversion ratio in piglets fed the 6% SDPP diet were better (p<0.01) than in those fed the 6% SDPI diet. When 3% of SDPP was replaced by SDPI, however, the growth rate and efficiency of pigs were comparable to those in pigs fed 6% SDPP. In conclusion, SDPP can be partially replaced by SDPI without any detrimental effect on growth performance in early-weaned pigs.
