Growth Performance and Heamato-Biochemical Parameters of Broilers Chicken Fed Different Levels of Pakia Biglobosa Leaf Extracts

This experiment was conducted to evaluate the growth performance and some hemato-biochemical parameters of broilers fed different levels of Pakia biglobosa leaf extract (BPE). Two hundred and fifty (250) one day old (Ross 308) broiler chicks were randomly assigned to five treatments with five replicate consisting of ten (10) bird each in a completely randomized design. Treatment 1 contained 0% BPE, Treatment 2, 3, 4 and 5 contained 5ml, 10ml, 15ml and 20ml per liter of water respectively. Clean feed and water were offered ad libitum throughout the experiment which lasted for 7 weeks during which data on performance, hematology and serum biochemical traits were collected. Results revealed that BPE had a significant (p<0.05) effect on final weight, feed conversion ratio and mortality rate. Birds given 20ml (T5) BPE recorded the highest weight gain (1846.1g) followed by 15ml (T4) with 1839.1g, 10ml (T3) with 1763.1, 5ml (T2) with 1757.1g and 0ml (T1) with 1679.0g respectively. BPE had no significant (p>0.05) on the feed intake of the birds. There was no significant (p>0.05) difference in PCV, Hb, RBC, MCV, MCH and MCHC values among the treatment. However, WBC and its differentials were significantly (p<0.05) influenced by BPE. Significant influences were not observed for albumin, globulin and total protein. Serum glutamic oxaloacetate transaminase (SGOT) and Serum glutamic pyruvic transaminase (SGPT) were significantly affected (P<0.05) as the level of BPE increased in the water of the animals. It was concluded BPE can be safely included in the water of birds at 15ml and 20ml without any deleterious effect on the performance and health of the animals.
