The means of feed intake, body weight (BW), feed conversion ratio (FCR), water intake, water intake: feed intake ratio, DM digestibility and digestive organ dimensions are shown Tables 3, 4 and 5. Data of digestive organ development is shown in Table 6. The data indicate that birds fed the coarser pelleted and crumbled copra meal diet had a significantly higher body weight and live weight gain than the birds fed either the fine ground or the fine ground + coarse crumbled diets (Tables 4 and 5). The difference in weight between the birds fed the crumbled and the fine diets was equivalent to approximately five days growth (Ross, 2002). Crumbled copra meal in the diet increased feed intake significantly. The water intake of birds fed crumbled copra meal in the diet was also significantly higher than for those birds fed the fine ground CM diet. The gizzard weight of birds fed the crumbled CM diet was heavier than for those fed the fine diet, but it was a smaller proportion of the body weight (Table 5). The addition of the enzyme mixture significantly increased protein digestibility and the body weight
(Table 4). The growth pattern of the birds indicated that the enzyme effect became evident when the birds reached 5 weeks of age (Fig. 1). Comparison of the weight and dimensions of different parts of the gastrointestinal tract found that the intestine, particularly the duodenum and the ileum, were different when enzyme was added to the diets. Birds fed the enzyme treated
