Pre vaccination care

Pre vaccination care Vaccinate healthy birds, if birds are sick postpone vaccination Handle the birds gently Vaccinate in cool hours of the day Avoid over crowding Maintain cold chain. Store vaccine at 4o C Keep record of all vaccinations, including batch no, brand, manufacturer etc. Prepare vaccine in suitable diluents, preferably one supplied by manufacturer. Use sterile glassware, syringe, needles, vaccine guns.

Provide 1 week interval between two vaccinations. Destroy left over vaccine, empty vials, neeedls etc. Use reconstituted vaccine with in 2 hours.

Pre vaccination care

Pre vaccination care Do not vaccinate the birds in disease. Avoid nasal vaccination in birds of respiratory problems. Store vaccine always in deep freeze. Vaccinate all birds at one time in a house. Increase the level of antibiotics in water/feed 3-4 days before vaccination. never mix two vaccines together to save time and labour. Use only distilled water for reconstitution of vaccine.

Vaccinate birds in the evening so that birds may rest over night. Provide birds with mycotoxin free diets.

Post vaccination care

Post vaccination care To reduce stress of vaccination anti stress medicines are used (3 days). Anti stress medicines: vit-A & E, probiotics, antibiotics, liver tonics and glucose. They are given through water. In case of vaccine failure give immunostimulants, vit A & E, selenium preparations and probiotics.

Factors that govern vaccination schedule

Factors that govern vaccination schedule Expired vaccines: never use Storage and transport: stored at 2-8 c. never store above 8 c. and transport in ice cubes or ice water is good. Avoid direct sunshine on mixed vaccines Do not vaccinate under high temperature: above 30 c may affect vaccine potency. Vaccinate during cooler periods of the day. Do not vaccinate sick birds: immune system of sick is weak.

Vaccines administered via drinking water: should be opened under the water into which it is to be mixed. b/s vaccines are vaccum sealed.

Factors that govern vaccination schedule

Factors that govern vaccination schedule 7) Health status of flock: should be done on healthy flock only. Postpone vaccination in event of any disease like coccidiosis. 8) nutrition: malnutrition like deficiency of protein in ration and high concentration of aflatoxins reduces response of birds to a particular disease. 9) stress: reduces production of antibodies in the body.

Aspergillosis

Aspergillosis Aspergillus fumigatus Mostly Effects lungs Occurs in brooding stage, so called as brooder pneumonia Transmitted by contaminated litter Deep litter system High moisture content in litter Respiratory distress, gasping, huddling prostration (reluctant to move)
