Three different forms of the diets were used; fine, coarse
and mixed pellet size. The crumbled CM diet was made
by pelleting and crumbling CM before mixing with the
other ingredients. All the other ingredients of the
crumbled CM diet were unmodified as received. The four
main ingredients (crumbled copra meal, maize meal,
soybean meal and fish meal) were mixed and then finely
ground before adding the minor ingredients (minerals,
vitamins, vegetable oil and enzyme) to form the fine
ground diet. The fine diet was mixed with the crumbled
CM diet in ratio of 1:1 to form the mixed fine and
crumbled CM diet. The diets were formulated using the
UFFF (Pesti et al., 1986) software program to meet
standard meat chicken nutrient requirements as
recommended by NRC (1994). The requirements of
amino acids were based on digestible amino acids
(Bryden and Li, 2004) (Table 1). To measure the particle
size, the diets were passed through four different screen
sizes (0.35mm, 0.71 mm, 1.00 mm and 1.70 mm). The
distribution of particle sizes in the diets is given in Table
2. Two different enzyme products, Allzyme SSF1
(0.04g/100g diet) and Hemicell2 (0.10 g/100 g diets)
were added to half of the diets.
