Abstract:
For this study, 125 one-day-old broiler chicks were procured from the local market. They were divided into five group A, 8, C, D and E and all groups were reared upto 45 days separately in different cages. All groups were provided with feed and water ad libitum and vaccinated. Disinfectants used to spray in the presence of birds of groups A, B, C and D were TH4, Prophyl, Beloran and Fourtedes, respectively. Group E was kept as control_. The disinfectants were sprayed once a week, starting from 1st week to 5th week of experiment, as per recommended doses. The average weight gain, feed consumed and feed conversion ratio (FCR) for all groups was determined on 15th, 30th and 45th day of the experiment. The proximate analysis of meat (pH, moisture, protein, fat and ash) of 5 birds of each group was conducted at the end of experiment. The mean values of weight gain by the birds of experimental groups were more than the mean values of the control on 45th day. Statistical analysis showed that experimental groups B, C, and D had significant difference (P<0.05) from control group E, but group A had non-significant difference from the control. FCR of all treated groups was better than the control. All groups had significant difference (P < 0.05) from the control except group A. Proximate analysis of meat revealed that there was non-significant difference among the control and treated groups.
