As you mention that egg weight is more than 79 gm. I think the breeder age may be above 70 wk. The early growth of feather is mainly due to nutrition and genetic
I agree with Mr. Mahmoud Refaat Mahmoud when he asks the unit of measurement of titres (11.2) because all other interpretations shall carry a meaning only if units are defined. For example 11.2 ( log2) HI titres are very high and could mean a recent…
Is your area endemic for ND ?
How is the MG status of the flock ?
I presume you are referring to a HI titer, though I prefer ELISA. What is the uniformity of the titer ? A mean titer could mean an average of very low and very high titers ?
Dear Dr,
ND titres 11.12 mean is definitely not " protective ".Please check with last 10 days production,hatchability as well as health condition of flock,also keep a keenwatch for next 10 days.If possible,retest the titres in this period, to reconf…
Hello!
Titre very low means birds are not exposed now - no problem of ND. However this level of titre no way near protective. If ND comes, it would affect that flock greatly. Revaccinate with live followed by killed immediately. Good level of ND HI…
How is the overall performance of the flock in terms of egg production, egg quality, and hatchability?
You mention "the last ND titers become mean11.12". When is "the last" exactly?
I have a broiler breeder flock of 30000 female at the age of 40 weeks. the last ND titers become mean11.12 . Now what I do either I revaccinate or not with ND live.
you can use the same male for both batches at their appropriate age of mixing. usually male mixed at the age of 22nd wk of female. You can use most mature male for first batch and less mature for second batch.
