This experiment was carried out with 30 growing pigs during a period of 14 weeks to examine the effects of additional levels of 0.1 and 3% of pine-needle meal on body weight gain. 1. The pig fed 1% pine-needle meal showed significantly (P $lt; 0.01) higher body weight gain. 2. Body weight gain of 3% was lower than that of 1%. 3. Effects of pine-needle meal was appeared at early stage of growing period. 4. Pine-needle meal adding by 1% is desirable for growth, economical value, disease control and feed efficiency.
