Abstract/ Executive Summary:

The research work was conducted to evaluate the effects of enzyme and protein supplementation on growth performance and hematological parameters in broiler chickens. A total of 80 (15 days old) broiler chicks were randomly divided into four groups (group A, B, C and D). Group A was considered as control, fed with commercial broiler ration, group B supplemented with protein (60% protein concentrate @10% with commercial ration), group C supplemented with an enzyme (Alquerzim(@ 1gl^-¹ drinking water), and group D supplemented with both enzyme and protein with the same dose, respectively. The experiment was continued for the period of 21 days. Results revealed that body weights were increased significantly (p<0.05) in all groups and highest body weights were recorded in Group D. Growth rate was highest at the 1st week (15-21 days of age) of experiment than the 2nd week (22-28 days of age) and no significant increase was observed in the last week (29-35 day of age). No significant differences were observed among the groups for PCV and TEC values. Hemoglobin (g dl^-1) content increased significantly (p<0.05) and ESR decreased significantly (p<0.05) in group D. Therefore, the study reveals that combined supplementation of protein and enzyme showed better result over control in respect to body weight gain, growth rate and hematological parameters.

Objectives:

The research work was designed to know the potential effect of additional supplementation of protein and enzyme on growth performance and improvement in the physiology of broiler chickens.

Methodology:

Experimental birds and design A total of 80 (15 days old, 550 gm weight) broiler chicks were used. The chicks were randomly divided into four equal groups (n=20). Temperature, feeder, waterer, feeder space, floor space, litter, room temperature, lighting,and hygienic measures were provided to the chicks according to the proto coldescribed by Mohiuddin et al. (2000). Birds of group A was considered as control fed with commercial ration. Group B supplemented with protein (Jasoprot®, protein concentrate 60%, Jayson Agrovet Ltd. @ 10% with commercial feed), group C supplemented with an enzyme (Alquerzim® @ l gl^-1 drinking water) and group D supplemented with both enzyme and protein at the same dose, respectively for 21 days. Body weight of an individual supplemented bird was recorded at 7 days interval up to the end of research. The birds were sacrificed to collect a blood sample for hematological study (TEC, Hb, ESR, and PCV). The research work was conducted in the Department of Physiology, Sylhet Agricultural University, Sylhet. Measurement of Body weight The body weight of each broiler was measured with assessing balance on the 15th day (1st day of the study) and sequentially at 7 days interval up to the end of the study. Hematological studies A blood sample was collected at the end of research. A number of sterile test tubes containing anticoagulant (4% sodium citrate solution) at a ratio of 1:10 were taken. Sequentially chilling was done and blood was collected from each group through slaughtering. The hematological studies were performed within two hours after collection. Total Erythrocyte count (TEC) were measured using hemacytometric method, Hemoglobin (Hb) concentration by hemoglobinometer and Packed Cell Volume (PCV) by Microhematocrit method according to standard procedures.

Achievement/Findings:

It could be concluded that combined supplementation of protein (60% protein@ 10% with commercial ration) and enzyme (1gl^-¹ drinking water) is beneficial for broiler growth without making any potential hazards to the physiology of the birds. Further studies are necessary to see any adverse effect in relation to histopathology and more serum biochemistry before making a definite conclusion regarding the economically beneficial field practice.
