The Growing Layer chicks of both sexes were fed the conventional diet contain 0.3% Quartz Porphyry (QP) and water and libitum during 18 days. Amount of feed intake was lower in the 0.3% supplement of QP but body weight gain and feed efficiency were significantly increased by 0.3% QP supplement.
The internal organs weight and length were not changed by feeding of 0.3% QP. When feeding of 0.3% QP, fatty acid composition was changed; ration of unsaturated fatty acid was increased.
No effects of supplement of 0.3% QP on the crude ash and mineral contents of on the tibia, thigh and breast.
These results suggest that supplement of 0.3% dietary QP was improves quality of meat in the growing chicks.
