Disease Monitoring Program For Export Broiler Farms Details of the disease-monitoring program for export broiler farms undertaken by private veterinarian: (A) General Inspection |
|
|
The veterinarian undertakes a general inspection of the farm at least once or twice a week to inspect the condition of the farm, animal husbandary management, bio-security protocols, poultry houses/infrastructures and clinical signs of any disease among the birds |
|
| (B) | Postmortem |
| The veterinarian carries out regular postmortem on culled and dead birds to determine the pathology and cause of death. | |
| (C) | Samples for laboratory diagnosis |
| If however the cause of death cannot be determined, the veterinarian will proceed to obtain organs samples to be sent to private or DVS laboratory | |
| (D) | Anti-microbial Sensitivity Tests |
|
Where applicable, anti microbial sensitivity tests are carried out at the laboratory to determine the most sensitive and suitable antibiotic to be used in cases of bacterial disease. This is to eliminate the need for broad spectrum antibiotics, to stop the unnecessary usage of ineffective antibiotics, to cut medication costs, to reduce cultivation of bacterial resistance towards antibiotics and to ensure the usage of anti-microbial is prudent and minimal. |
|
| (E) | Vaccination Program |
| Comprehensive
and effective vaccination program to prevent outbreak of diseases such as: a. Newcastle Disease b. Infections Bursal Disease c. Infectious Bronchitis d. Pasteurella multicida (Broiler duck) The vaccination schedule and strain type of vaccine used has to be relevant to current findings or isolation of ND/IBD/IB outbreaks in local areas. |
|
| (F) | Serology |
| To collect serum samples from birds to be sent for antibody titre at private laboratory. The serum samples are collected at appropriate schedule to gauge the efficacy of vaccination program and the adequancy of the antibody titre of each flock | |
| (G) | Monitoring of Salmonella enteritidis, Vancomycin-resistant Enterococcus and Campylobacter |
| Every alternate batch/cycle will be monitored. Details of the program are as follows: | |
VANCOMYCIN-RESISTANT ENTEROCOCCUS |

| (H) | Disease monitoring program report |
| The
farm veterinarian is responsible to record all findings and activities
related to the disease monitoring program for every batch/cycle of
production In farms that have quality system in their management, the diseases program must also be included as part of the quality system. The veterinarian is responsible for proper reporting and shall be responsible to present the report to the DVS or AVA officers. Note: (a) Implementation of the Campylobacter monitoring has yet to be stramline due to the need to establish the private laboratory capabilities, specimen handling and cost incurred for each test. (b) The disease program is subjected to changes or improvements whenever required |
