Detailed Technical Analysis & Market Intelligence
Minimizing vaccination and procedure-related stress is vital for brown pullet development. Administering vaccinations against yolk sac infection and early chick mortality during the early brooding phase allows the bird to recover quickly without affecting its feed intake. Combining these procedures with adding oyster shell or coarse limestone grit in afternoon feed and stable pullet vaccination schedule (recombinant Gumboro, ND, IB) is the standard protocol.
