Q and A: Management of Newcastle & Viral Diseases

by

Question: A friend’s birds started laying and have reached 50%. She was advised not to vaccinate Newcastle till they peak. Now she has noticed 2 that developed twisted necks. What should she do?

Dr. David Omoding – Quality Chemicals: The long-term health of the birds cannot be compromised for production performance. If vaccination is due, it should be done regardless of production level

Dr. Sewagudde Samuel – Genesis East Africa Ltd: Some birds can react post vaccination, 10- 14 days later, and show signs of disease, but with use of antibiotics, you can help them fend off the associated infections

Background to Answers:
Viral diseases like NewCastle and Gumboro normally destroy or weaken the immune system, just like the Humman Immuno-Deficency Virus (HIV) for humans. This then allows bacteria to take advantage of the reduced of immunity to cause further havoc through secondary intestinal, respiratory and other infections which further reduce productivity and potentially cause mortality.

Therefore treat such situations with antibiotics and vitamins to kill the bacterial and boast the immunity. Common antibiotics trade names include Keprocoeryl, Tetracycline 20% or 25%, Enrosol, etc. The vitamins combos include Amino vital, Aminovit, Cholivit, Vitalyte, etc

Quality Chemicals Uganda Limited also has vaccines of all kinds for poultry and larger animals. The latest on their list is the thermal stable Newcastle vaccine which does not need to be maintained under cold conditions, and soon the injectable Newcastle given prior to laying reducing the need for continous boosting during laying.

Vaccination Schedule up to Week 12

by

Well today the chicks make 3 weeks, and we are going ahead with our regular vaccination schedule. I decided to share our schedule for others to learn and comment on. The vaccination is done every Thursday (Day 0) so every week mentioned below is based on the day the chicks were delivered 

  • Day 7 (Week 1) – IB via drop in eye
  • Day 10 – Mareks via injection under the wing 
  • Week 2 – Newcastle via drop in eye
  • Week 3 – Gumboro via drop in eye
  • Week 4 – Newcastle
  • Week 5 – Gumboro
  • Week 6 – Newcastle
  • Week 7 – Gumboro
  • Week 8 – Fowl Pox  
  • Week 9 – Fowl Typhoid 
  • Week 10 – Newcastle
  • Week 11 – Gumboro 
  • Week 12 – Debeaking 

After Week 12, I will update the schedule accordingly when the time comes  

Vaccination – Preparations and Setup

by

Yes, we had a tough first week, but we lived through it although the losses were up to 10% of what we received, this is pretty high, but being inexperienced we can put it to the costs of learning on the job.

The vaccination schedule is every week for the next 12 weeks, with Newcastle and Gumoboro being alternated, I will post our vaccination schedule once I get round to typing it up. 

Here I explain how we setup for vaccination for those who like me are learning on the job. Pre-vaccination checklist:

  1. No vitamins or other medication in the water for the day before
  2. No water provided to the chicks for 2 hours before the vaccination, apparently to assist in ingestion especially the ocular ones which are administered one drop in each eye

First we created two separate areas within the brooder using plywood 

Brooder with separator for chicks vaccinated and those that are not

The vaccination operation was manned by 3 people – two vaccinating and one picking up the chicks and passing them to the other two. The reason for this is efficiency (due to split roles), but also to ensure that the operation is done quickly so that the vaccine remains chilled.

And once the vaccination is done the plywood is removed and the chicks are back to using the whole room as their playground. Also there is countinous monitoring for any changes in the behavior and feeding habits
