The dose is fixed by the manufacturer. no point in doubling it.Slips in vaccination is a problem associated with large flock size and hurrying man power. repeating the vaccination will be better.

I came across a problem due to improper grinding of feed. The feed was balanced but consumption was irregular. The problem was resolved after changing the feed lot with same formula but ground uniformly.

India has not gone to rispense yet. SB1+HVT is doing well.
Proper handling of vaccine maintaining cold chain is very important.
Marek's vaccine virus has to reach the cell receptors before the field virus reaches. If the brooder houses are contaminated, the field virus moves faster. If the brooder house had an earlier incidence of Marek's cases, better delay the placement of chicks by over night ...

There are calculations in the literature to calculate the energy requirement per given weight. Brody formula is body weight raised to the power of 0.65. the feed for added growth is calculated at 1.5 FCR. an other way we tried is full feeding of broilers with pre starter and starter. the approximate feed consumption on 22nd day is around 80gms. we found that the daily feed on ad libitum feed at 40 ...

Adding salt to water 0.5gm pet liter or up to 4kg per ton (total not additional) will help reduce picking. Debeaking at this stage will reduce production but picking will be controlled. The aggres ...

Generally, the pfu available in Marek's vaccine are more than prescribed. most important is the brooder house. it the house had earlier incidence and not properly cleaned and rested, the chicks are exposed to field virus which reaches the receptors of the cell surface faster th ...
