ABSTRACT
In an experiment, the influence of phytase enzyme
supplementation in the diet of starter broiler . chickens was evaluated. 180
broiler chicks of Ioda breed were used for the study. The chicks were brooded
with a commercial broiler starter mash for one week using standard facilities.
Regular heat and light were supplied using electric bulbs throughout the period
of the experiment. Brooding temperature was adjusted according to changes in
ambient temperature and behavioural changes of the chicks. After a week, they
were allotted to five iso-nitrogenous (21.50% CP) and iso-caloric (2977.40
kcal/kg ME) dietary treatments compounded to contain 0g/100kg (T;), 10g/100kg
(T2), 15g/100kg (Ts), 20g/100kg (T. 4) and 25g/100kg (Ts) of a commercial
phytase enzyme preparation for 21 days in a completely randomized design (CRD).
Feed and water were provided to the chicks ad-libitum using feeders and
drinkers. Daily feed intake and weekly weight changes were measured. The result
showed that the, daily feed intake (g), and daily protein intake (g) were not
affected (P>0.05) by enzyme supplementation. Final live weight (g), daily weight
gain (g), total weight gain (g) and protein efficiency ratio were significantly
(P<0.05) higher in T1 (2.11) than TS (1.80) but similar to T2 (2.05), T3 (2.05) and T4 (1.96). Feed conversion ratio was statistically (P><0.05) different in Ts (2.58) and T; (2.02) but similar (P>0.05)
in T1 (2.02), Tz (2028), T3 (2.31) and Ty (2.38). Mortality (%) was lowest in
TS (0). Total feed cost per bird (A) and daily feed cost per bird (@¥) were not
affected (P>0.05) by - enzyme supplementation while cost per kg of feed (A)
and cost per kg weight gain (@¥) were significantly (P<0.05) lower in T, and T2 than Ts but similar (P>0.05)
in T;, Tz, T3 and Ty. The result of the study has indicated that phytase enzyme
could be supplemented upto 20g per 100 kg in the diet of starter broiler
chickens.
