Abstract
In the previous report, authors suggested that significant differences were observed in chemical components of bulk feed. This report deals with the variation of the granular and chemical components of the feed packed in both 500kg. and 20kg. bags. Also, the comparison with the variation of bulk feed was discussed.
Commercial formula feed for layers was used in this experiment. Feed in 500kg. bag was delivered about 95km. and in 20kg. bag about 80km. by truck. Procedures of analysis are the same as previous report.
Results obtained are as follows;
1) Significant differences were observed in chemical components of feed in both 500kg. and 20kg. bags.
2) More significant differences were observed in chemical components of the feed in bags than the feed in bulk. Due to the large mean square of the error in bulk feed, it was impossible to find the statistical difference.
3) Coefficients of variation of chemical components of bulk feed were large but there was no difference between 500kg. and 20kg. bag packed feed.
