Materials and Methods: The raw fresh milk was collected from 18 lactating cows before antibiotics treatment, which were brought to the veterinary hospital and suffered from either mastitis, foot and mouth disease, fever, local wound, or non-specific diarrhea, and so on. Out of the 18 lactating cows, six were treated with oxytetracycline, six were treated with amoxicillin, and six were treated with ciprofloxacin parenterally. Milk samples were also collected at 2nd day during treatment and final collection was done after maintaining the withdrawal period. Since milk is heated before consumption, it was boiled at 100°C for 20 min to evaluate the thermal effect on antibiotics residual status. Thin-layer chromatography was done for screening of antibiotics residue before and after boiling of the milk. Results: At day 0 (before antibiotic treatment), no antibiotics (oxytetracycline, ciprofloxacin and amoxicillin) residue was detected in raw milk of antibiotic treated cows. In contrast, on day 2 (during antibiotic treatment), 100% raw milk samples showed positive for antibiotics residue. After boiling, all milk samples showed positive for such specific antibiotics residue. On the other hand, no antibiotics residues were detected on day 9, which indicates the completion of the withdrawal period of the respective antibiotic. The intensities of bands for antibiotic on thin-layer chromatography plate of antibiotic residues in milk samples (oxytetracycline, amoxicillin, and ciprofloxacin) expressed that the respective antibiotic residual status was higher in the boiled milk compare to the raw milk. Conclusion: Proper maintenance of withdrawal period after antibiotic treatment would minimize the risk of antibiotic residues in milk, and boiling does not change these specific antibiotics residual status in milk. Therefore, awareness regarding the proper maintenance of withdrawal period after antibiotic treatment in lactating cows is one of the best strategies that may positively reduce the risk of antimicrobial drugs residue in milk.

This study was designed with the aim to investigate the effects of residual antibiotics on hematological parameters of broiler following discriminate and indiscriminate use. Broiler chicks were reared accordingly upto 30 days and on day 14 the chicks were randomly divided into 3 groups (n=6) namely control (group A), discriminate (group B) and indiscriminate (group C). At the age of day 16, amoxicillin treatment was started and continued for seven (7) days for in discriminate group (Group B) and fifteen (15) days for indiscriminate group. In case of discriminate group withdrawal period was properly maintained as nomenclature (Seven days) whereas, there was no withdrawal period in case of indiscriminate group. The hemoglobin (gm%) of control, discriminate, and indiscriminate group was 7.07±0.099, 6.97±0.095, and 6.90±0.124; Total erythrocyte count (TEC) 2.55±0.044 million/mm3, 2.53±0....

Farm generally used acaricides to treat tick infestation; however finding new, cheap and alternative source of acaricides is a prime concern. Here, we investigated the in-vitro efficacy of verenda (Ricinus communis) leaves extracts to treat tick infestation. We prepared aqueous, methanolic and ethanolic extract of verenda leaves to apply on ticks. A total of 90 ticks (both hard ticks and soft ticks) was collected from cattle in local area of Mymensingh region and divided into 3 treatment groups: A (aqueous), B (ethanol), C (methanol) and D (control). All groups were sub-divided into 3 sub-groups on the basis of concentration of 1%, 2% and 3% treatments. Ticks were treated with different concentration of extract and observation of tick was performed 12, 24 and 36 hours interval. The whole experiment was repeated thrice. Our data suggests 3% methanolic extract confer highest efficacy aga...

According to the case record, a total of 5036 sick animals were examined and 103 types of diseases were identified during this period. The commonly found various diseases were parasitic disease (33.86%), myiasis (5.96%), PPR (5.16%), pneumonia and pneumonitis (4.11%), repeat breeding (2.88%) and rest of the diseases had lower percentage than 2.5%. Out of the 5036, 1759 cases (35%) were male and 3277 cases (65%) were female. Animals aged between 1-3 years had high occurrence (45.23%) followed by 0-1 year (25.11%). Diseases in digestive system were mostly affected (33.79%) and lowest in cardiovascular system (0.65%). Occurrence of diseases was highest (36.81%) in rainy season (June-October) followed b...
