The volume is another issue to consider. In-ovo vaccination entiles microliters whereas in-ovo feeding entiles milliliters. Equipment has to be adjusted to handle such difference in volume and the time to process the same number of eggs might increase. Some breeds are already growing at such fast pace that even the slightest boost in growth rate may increase the incidence of leg problems.
Not so long in ovo vaccination had been an onerus task , today it becomes a reality and an easy business but it is not hetherto somthing that is generalized .By the same token in ovo feeding may be tomorrow a reality but cost-effectiveness analysis should precede its introduction !!!
IT IS A VERY GOOD METHOD,BECAUSE DUE TO INITIAL STRESSCHICKS ARE EXPOSED TO VARIOUS DISESAES,WHICH FURTHER AVOID THE EARLY CHICK MORTALITY.IN THE BEGINNG PERIOD ONLY CHICKS ARE HAVING MORE VACCINATION SCHEDULE,WHICH INTUR DEVELOP THE BETTER IMMUNITY.
It is difficult to implement when customers are having more number of satellite hatcheries at different parts of the country.The cost is the main criteria and the successs of this technique is based on Cost Benefit Ratio. If Return on investment can be shown what could be the minimum size of the chicks produced from hatchery?.
What matters is whether the process, using mechanised in- ovo equipment actually delivers improved weight/yield/marketable mass through the plant!So far it has not. We do not market 7-day broilers and poults and we do not sell intestines. One of the equipment manufacturers funded extensive research which led nowhere. Simon Shane
After the invention of in-ovovaccination technoloy,the idea of what about In-Ovo feeding came into scientific mind. experimental studies revealed very promising results.Global applicability of the technology will depend on: Benefits against costs. User friendly technology. Impect not only on growth but also on natural defence mechnism of the bird, Safety ofPouring/injecting exoginous materials into chick still inside egg(animal welfare).

The technique will touch two main points ,technical point of application methods which practically can not be done 100% on the field.and ecnomical point covering the out come of the technique considering the cost of nutrients ,and application. Bi-technique norshing &immunizing may be of potential.
The global pratical application is my main concern.If tested, how reproduceable and how would the technology be affordable.In-ovo applications are burdensome on chicks already. Would there not be incompactibility even if sites of action are different.We may have to look into these. Meanwhile,the 'super benefits' can not be ignored.
this technology is very expensive. using the higH quality food after hatching is more better than in ovov feeding. i am not agree with injecting day old chicken and using liquid feed after hatching is more friendly and better for animal. i think less injection for all animal and respect to them is accordant to animal right.
The practical of this approach for the poultry industry on a global basis will depends on the their results in the filed, development of easy instruments for the injection, education to mimic losses of eggs at this stage, the most important may be if the this approach could be developed to improve immunity at this stage. Cost-benefit analyses should be done to compare the cost against the benefits. Improving immunity may be a potential factor, besides improve gut ecology, and early pancreatic functions.
