Effect of In ovo injection with Newcastle Disease Vaccine, Multivitamins AD3E, and Omega-3 on Carcass Characteristics of Broilers

It is hard to appreciate the findings in this study especially when moisture data was not presented. The significant difference in dressing % ( about 10 % between control and treatment with vitamins or omega 3) may just reflected the difference in moisture content. How about antibody titers against NCD of vaccinated broilers? final weights of birds under each treatment and blood cholesterol?

is there any recommendation for vaccination with unsaturated fatty acid and vit AD3E ? Incubation period vaccination perhaps with vitamins and omega3 fatty acids is bit confusing. My worry is do embryo of 19-21days did had deficiency of vitamins and fatty acids. Is the killed ND compatible with 3omega fatty acid and vits? I think such reports also say that we can manipulate the carcase quality, body wt at different ages, hatching % through such technique. This study also let me to find how was mother's nutritional status? Is the hatching eggs suffer from deficiencies so that we have to put more nutrients along with vaccination ND killed. well good references are there to support in ovo treatments for better performance during post hatch period. Let us see how far we can establish such impacts except vaccination alone. Hope such studies need more confirmations all over world for better future. dr m rath
