PROPERTIES

BIO-VAC LS-H120 is prepared using the attenuated La Sota strain of Newcastle disease virus and the attenuated Massachusetts H120 strain of Infectious Bronchitis virus, cultured on embryonated SPF eggs to ensure the highest safety, freeze-dried and vacuum-sealed.
The immunity provided by this vaccine reaches peak levels at 10-15 days after administration; however chickens benefit from a good protection against both infections already a few days after administration, on account of the phenomenon of interference.

INDICATIONS

Prophylaxis of Newcastle disease and Infectious Bronchitis.

ADMINISTRATION

This vaccine may be administered:

Oculo-nasal route:
Dissolve the contents of the vial in appropriate diluent; using appropriate dropping nosel, pour one drop in the eye and in the nostril of each subject.

Drinking water route:
Dissolve the contents of the vial in a small quantity of water, then pour it into the quantity of drinking water deemed necessary for administration. Rinse the vial and carefully mix the vaccinal water before distribution. The quantity of water necessary for even vaccination varies according to the age of the subject, the season and environment temperature.

The following scheme shows the minimum and maximum volumes of water for every subject:

Chicken age	Quantity of water (in ml)
0-2 weeks	7-10
3-5 weeks	10-20
6-12 weeks	20-60
over 12 weeks	50-80

In order to obtain good results from the vaccination in drinking water, the following instructions should be followed:

1) make sure that no antiseptic or disinfectant substances are contained in the drinking water or in the troughs. Even traces of these substances might inactivate the vaccinal virus;

2) if possible, utilize enamelled, plastic or glass troughs;

3) make the animals thirsty by cutting water administration for at least 3 hours;

4) distribute the water containing the vaccine in a number of troughs to permit all animals access to the vaccine within 2-3 hours.

DOSAGE

BIO-VAC LS-H120 can be used with animals of any age, after verifying their good general condition of health.
For broilers, it is advisable to perform a previous vaccination at 4-8 days with BIO-VAC ND-IB and a second one (a booster dose) with BIO-VAC LS-H120, 3 weeks after the first administration.
In case of future layers, besides the two vaccinations at the same age advised for the broilers, a third vaccination is necessary, before the beginning of the laying period, i.e. between the 15^th and the 20^th week; then an interval of about 4 months.
