This study was conducted to investigate the nutrient evaluation of apple by-product as protein source in growing pigs diet. A 14-day trial with 10 [(YorkshirexLandrace)xDuroc)] finishing pigs (average body weight = 30 ㎏) was conducted to investigate the dry matter (DM), energy (E) and nitrogen (N) digestibility and utilization. Treatments of this study included: 1) CON (basal diet) and 2) ABP (basal diet + 2% apple by-product). With regard to DM and E digestibity, there were no significantly differences (P>0.05). Also, with regard to N utilization, there were no significantly differences (P>0.05). In conclusion, apple by-product, incorporated up to 2 percent in the diet of 30 kg pigs, did not show any adverse effects on nutrient utilization as protein source.

Apple pomace is a by-product produced in the process of manufacturing apple juice, and most are discarded. Some of apple pomace are used as feed for ruminant. On the other hand, in monogastrics, apple pomace is rarely used. However, in many previous studies, it has been demonstrated that apple pomace can be used as feed material for broilers and pigs. In addition, apple pomace has the effect of reducing feed costs, and effect of reducing environmental pollution by using waste resources. Therefore, it is recommended to replace some of the existing feed ingredients, corn and soybean meal with apple pomace

This study was conducted to investigate the effect of various corn size as energy source In vitro digestibility in pigs. Treatment of this study included: 1) T1 (particle size : 200 microne) 2) T2 (particle size : 300 microne) 3) T3 (particle size : 400 microne) and 4) T4 (particle size : 800 microne). With regard to dry matter (DM) or organic matter (OM) digestibility, T1 were higher than T2, T3 and T4 (p<0.05). Also, T3 was similar to T4. In conclusion, DM and OM were affected by particle size in In vitro total tract digestibility.
