The effect of Mycoplasma meleagridis infection and egg dipping on the weight-gain performance of turkey poults.
Turkey poults were observed throughout their first 7 weeks of life to evaluate the effects of embryonic infection with Mycoplasma meleagridis (MM) and the effects of a control measure, egg dipping with tylosin and gentamycin. Fifty-thousand poults from four sister flocks were divided among eight groups according to MM-infection status [MM (+) or MM (-)] , sex, and egg-dipping status (dipped or nondipped). These birds were raised under natural field conditions in the Central Valley of California. The MM (+) poults had significantly (P less than 0.05) greater weights during the first part of the trial and, although usually not significantly (P greater than 0.05), consistently during the later part.
