KEEP BROILER PRODUCTION EFFICIENT
Optimize the processes
Ease the processes
Safeguard performance
Do as much as possible in the hatchery
hatchery vaccination- (s/c, in ovo)
•Equipment to standardize, less labor• Minimum and early reaction• No disturbance during growing period
MOVE VACCINATION AS
MUCH AS POSSIBLE INTO

• Fewer hatcheries than farms ( Hatchery Vs Farms )
• Easier to control standardized procedures (SOP )
-Preparation and administration
• (semi) automatic equipment
-standardize, uniform application, reduce human factor
• Create uniform conditions
Easier to control temperature, relative humidity and light
• Introduction of new Hatchery vaccines

Recombinant vaccines
• Recombinant vaccines are based on new technologies of molecular engineering
• It is all based on the technology of the recombination of the DNA (genetic engineering)
![Page 16: Recombinant Technology for ND and MD Vaccine strains€¦ · Day-old Sub-cutaneous injection In ovo Recombinant Hatchery vaccination. Perfect fit in: Innovating with Science First](https://reader034.fdocuments.us/reader034/viewer/2022042208/5eab41f862092c0dad439ffa/html5/thumbnails/16.jpg)
Recombinant vaccineswe have single construct and dual construct vaccine on the market
• Consists of a vector (virus or bacteria) expressing foreign antigens
• Genes that codify for 1 or more antigens (proteins) are introduced in the vector’s genome
• The immune response (cellular & humoral) is against the vector, including the inserted antigen(s), without the need of using the causative agent

The HVT part will still induce marek protection up
to the level of related to HVT
The F-protein will induce F-antibodies and
The F antibodies will neutralize the F protein of
ND virus “blocks” (prevents) the infection of the
chicken after a NDV field exposure.

Advantages of a recombinant vaccine
• Absence of post vaccination reaction
• No interference with ND MDA or other vaccines
• No dissemination of vaccine virus
• Convenient and homogenous administration (in-ovo or day-old hatchery)
• Act as a marker vaccine (DIVA: Differentiate Infected from Vaccinated Animals )
• Ease vaccination program 2 in 1
![Page 29: Recombinant Technology for ND and MD Vaccine strains€¦ · Day-old Sub-cutaneous injection In ovo Recombinant Hatchery vaccination. Perfect fit in: Innovating with Science First](https://reader034.fdocuments.us/reader034/viewer/2022042208/5eab41f862092c0dad439ffa/html5/thumbnails/29.jpg)
Recombinant Vaccines: Characteristics
• Development of immunity depends of the replication of the vector
• Need of priming with conventional ND vaccines in high challenge areas
• Serological monitoring is different
