Abstract/ Executive Summary:

The study was carried out to know the effects of probiotics (Proctxin^® Boost, Novartis Bangladesh Ltd.) and antibiotic (oxytetracycline-Renarnycin^®, Renata Animal Health) on growth performances and haemato- biochemical parameters of "Shaver Star Bro" broiler chickens during September and October 2003. A total of 20, day old broilers were randomly selected and assigned into four equal groups n = 5) as A, B, C and D. Group A was considered as control group fed with commercial ration while groups B, C and D were fed with commercial ration with the addition of 200 mg probiotics/ liter drinking water, 100 mg probiotics and 50 mg antibiotic (oxytetracycline- Renamycin^®)/ liter drinking water and 100 mg antibiotic (oxytetracycline- Renarnycin^®)/ liter drinking water respectively up to 35 days of age. The results showed that the body weight gains differed significantly (p<0.05) at the 2^nd, 4^th and 5^th weeks of age in different treatment groups. The meat yield not differed significantly (p>0.05). The drumstick, wing differed significantly (p<0.01) and spleen weight differed at p<0.05 among different groups. The mean haemato- biochemical values of Hb, ESR, PCV, heterophil, eosinophil, basophil, triglyceride, HDL, LDL, SGPT and SGOT were differed significantly (p<0.01) in different groups. The present findings suggest that supplementation of probiotics has significant effect on growth performance and certain haemato- biochemical parameters of broiler chickens as compared to antibiotic supplementation.

Objectives:

To know the effects of probiotics and antibiotic on growth performances and haemato- biochemical parameters of "Shaver Star Bro" broiler chickens.

Methodology:

The present research was conducted during September and October 2003 in the Department of Physiology, Bangladesh Agricultural University, Mymensingh. A total of 20, day-old broiler chickens of "Shaver Star Bro" strain were purchased from Kazi Farms Ltd., Dhaka. The birds were randomly assigned into four equal groups as A, B. C and D, each consisting of 5 chickens and were reared in well partitioned area in a room under strict hygienic management in the experimental poultry shed of the Department of Physiology, BAU, Mymensingh. Group A was considered as control group fed with commercial ration while groups B, C and D were fed with commercial ration with the addition of 200 mg probiotics/liter drinking water, 100 mg probiotics and 50 mg antibiotic (oxytetracycline- Renamycinf^®)/liter drinking water and 100 mg antibiotic (oxytetracycline- Renamycin^®)/liter drinking water respectively up to 35 days of age. Vaccination schedule for Newcastle disease and infectious bursal disease was maintained properly. The body weight of each bird of all the four groups was taken weekly during the 35 days of experimental period. All the birds from each group were sacrificed to calculate the meat yield and organ characteristics at the end of the experiment. Birds were dissected and to facilitate slaughtering, all the birds had their feed and water withdrawn 12 hours prior to sacrifice. Breast meat with keel bone, thigh meat with thigh bone, drumstick meat with drumstick bone and wing meat with wing bone were separated from the carcasses. Weight of the meat and internal organ were taken by electrical weight machine and expressed in percentage of the live weight. Blood sample for haematologic and serum analyzes were collected at the end of the experimental period in double-oxalate containing and plain tubes, respectively. The haematological studies were performed within two hours of blood collection. Total erythrocyte count (TEC) and haemoglobin (Hb) were determined by Haemocytometer and Hellige Hemometer (Sahli type) respectively and packed cell volume (PCV) and erythrocyte sedimentation rate (ESR) were measured by Wintrobe haematocrit tube. Differential leukocyte count (DLC) was also done by the procedure. Serum biochemical (Total cholesterol, Triglycerides, high density lipoprotein and low density lipoprotein cholesterol) analyzes were performed colorimetrically using Humalyzer 2000 (Human type, Germany). Serum glutamate oxal-acetate transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT) values were measured by using Reflotron^® analyzer (Mahnheim, Boehringer, Germany). Analysis of Variance was done with the help of computer package MSTAT- C. The mean differences among the results of different treatments were determined as per Duncan's Multiple Range Test.

Achievement/Findings:

From the present study, it was indicated that there was better growth performance of broiler chickens with the supplementation of probiotics @ 200 mg/litres drinking water. The present study suggested that supplementation of probiotics has significant influences on weight gain and haemato- biochemical parameters inbroiler chickens compared to antibiotic supplementation.
