Abstract
The effects of 6/85-strain M. gallisepticum (6/85MG) inoculation alone or in conjunction with a F-strain M. gallisepticum (FMG) over-lay and its timing on the performance, egg, blood, and visceral characteristics of commercial egg laying hens were investigated. The applied treatments did not affect layer performance, but did affect yolk moisture and fatty acids, liver moisture, and plasma protein. The plasma protein and liver moisture changes may be indicative of the effects of the treatments on the hydration statuses of the birds during lay, whereas alterations in yolk palmitic, oleic, and linolenic acid levels with treatment may have been manifested by disturbances in the desaturation and elongation processes of fatty acid synthesis. Pre-lay 6/85MG inoculations may be a suitable substitute for pre-lay FMG inoculations and FMG overlays during lay on pre-lay 6/85MG inoculations may provide continual protection without eliciting any subsequent suppressive affects on performance.
