Animal Health and Management
Test ingredients: Fresh garlic was purchased from KR Shopping centre, Bangladesh Agricultural University campus. The garlic was peeled, cut into small pieces and dried at 40°C for 24 hours. The dried garlic was crushed by grinder and aqueous extract was prepared by Soxhlet extraction. One percent and 2% solutions of garlic extract were prepared. Birds' management: A total of 40 day-old Cobb 500 broiler chicks were purchased from a hatchery at Gazipur, Bangladesh. The chicks were kept for nine days for acclimatization and were fed commercial broiler starter feed and drinking water. The brooding temperature was maintained at 35°C during the first week, and then lowered by 3°C every week until it reached room temperature (25 ± 1°C). Mean initial weight of the chicks was 35.9g. Newcastle disease vaccine was given intra-ocularly at 4th and 21st days. On day 7, 40 chicks with mean body weight 91g were allotted to two treatment and positive and negative control groups in a completely random design (CRD). The birds were reared in iron cages of 5 × 4 × 3.5 feet. Four experimental groups were identified as T1 (1% garlic), T2 (2% garlic), Nc (negative control: only feed and water) and Pc [positive control: antibiotic, Vitamin B-complex and pesticide] supplied as pharmaceuticals recommended dose. Data collection: Birds were weighed every day. At the end of treatment blood samples were collected from the wing vein of each bird using disposable plastic syringe and needle with EDTA. After sacrifice, dressing percentages were taken and liver, heart, pancreas, gizzard and spleen were weighed. Haematological assay: Packed Cell Volume (PCV), Total Erythrocyte Count (TEC) and Haemoglobin concentrations (Hb) were measured. Statistics and data analysis: The data were analysed using general linear model procedure of Statistical Package for Social Science (SPSS) IBM 20, and comparison of means tested using Duncan’s multiple range test: significance was considered at P<0.05.
