Abstract: This research was conducted to determine the effect of enzymes & vitamin on the physio- haematological parameters of broiler
turkey birds (Melliagris gallpavo gallopavo) which were obtained from Big Brothers Farm (B &B) from Ilorin Kwara State. Sixty birds were used
for the study. Same feed were given to the birds, the birds were grouped into four groups labeled as A, B, C and D, each group consists of fifteen
(15) birds. Group A was maintained as control and placed on feed and drinking water throughout the experimental period. Group B was placed
on enzymes at 1g/litter of water, group C was placed on vitamin at 0.5g/liter of drinking water and group D was placed on combination of enzymes
and vitamin at the rate mentioned above. All the birds were fed the same commercial feed throughout the study. Initial body weight was recorded
and subsequently, body weight was recorded at 7 days interval up to the end of experimental period and on the final day of the experiment blood
sample were collected using 5ml syringe and 25 gauge needle via the wing vein for hematological haemoglobin (Hb), packed cell volume (PCV)
red blood cell (RBC), white blood cell (WBC), study. The results revealed that mean value of WBC in all treated groups increased numerically with
the highest value recorded in group D (242.96+15.35) However, statistically there was no significant increased (P>0.05) in all the treated groups.
The mean value of RBC increased significantly (P<0.05) in all the treated groups and the highest value was recorded in group D (2.62+ 0.17)
million/mm3. Similarly, the mean hemoglobin values increased significantly (P<0.05) in all the treated groups and the highest was recorded in
group D (14.26 + 3.56) g/dl. The mean value of PVC similarly showed a significant increased (P<0.05) in all the treated groups with the highest
value recorded in group D (42.66 + 0.21%). On platelets, no significant difference (P<0.05) was recorded in all the treated groups. On body
weight there was an increased body weight gain numerically in all the treated groups than control group. The data showed that numerically on the
7th day there was an increase in body weight, however, statistically no significant difference (P< 0.05) was recorded in all the treated groups.
Similarly, on day 14th, 21st, and 28th there was a numerical increase in body weight in the treated groups and the highest value was always recorded
in group D in all the weeks. It is concluded that enzyme and vitamin has no negative effect on the turkey broiler birds, it rather enhance digestion
utilization, performance and hematological parameter of turkey birds was not altered. Enzyme and vitamin should be used to enhance performance
of the bird and a similar study should be carried out using the same enzyme and vitamin in turkey birds to see their effect in terms of egg production.
