Cracking down on Poultry Disease with egg yolk

It's not mother's milk, but egg yolk may be the closest remedy for boosting the immune system of newly hatched chickens against infectious diseases such as coccidiosis. A major disease of chickens, coccidiosis is caused by intestinal parasites—single-celled protozoans in the genus Eimeria. Disease-affected birds are unable to absorb feed or gain weight, costing the poultry industry more tha...

Dear Sandra (USDA)

It is a good method to fight against coccidiosis. But the problem will be for vaccines. That there is' a cross-immunity, because there are several Eimeria species. On the other hand it will be the price of these additives based on egg yolk. If they are expensive as vaccines, poultry farmers will refuse their use

Re: Cracking down on Poultry Disease with egg yolk

08/15/2012 | Dear author,
It looks very much acceptable and ideal for controlling intestinal status from the disease angles due to bacterial and protozoan infections. The extent I was happy to know the idea at the same extent thought about the biological cycle of poultry and mechanism of transferring passive immunity to yolk through female parent metabolism and the complex mechanism involved for growth of the ovary and development of ovary and ovulation process, time taken to accumulate the immune- globulin in the egg yolk for specific diseases though portal circulations are few more points need examination. How far it is established that the highly rich immunity inducing proteins from SPF eggs would reach to blood levels to additionally support the inherent passive immunity for the gut disease protections. If I have to add 0.5% in the starter feed or any other special products during the period from 1-10days how the product will maintain the immune-globulin quality ideal for getting absorbed and support for immunity of development when it may come contact with external environments like feed and water etc. Further, if I think I can use this product for feeding to breeder birds to push more immune-globulin in side the female parent then i may expect support the mother to take up the biological translation of moving the items to yolk effectively within biological conditions inside body and body system.Again the SPF egg cost and product developments may impact the breeder feed cost and it can be acceptable only when the costing come through. However for active immunity we have to carry on the vaccinations for viral diseases till alternative to no vaccination situation appear to us.
I would like to add that many broiler and layer production units have some nutritional formula e which contain MBM and fish meal and tallow which are more attracting bacteria to the gut when these get moisture contacts during processing of feed or storing in room temp. So many nutritionist suggest to add antibiotics in the formulations or post feeding time to control these bacteria or feed pro-biotic products without sealing the more chances of allowing bacteria through these sensitive products to reach gut. Thus I feel veg feeding would be ideal for limiting bacterial load and reducing uses of antibiotics and more using pro biotic concepts. Thank you for allowing me to write some thoughts. Dr M.
