English to Spanish Science Livestock / Animal Husbandry field study - vaccines

Hatchability data will be collected for the birds inoculated via the in ovo route and will be compared to the non-test birds receiving the cooperator's normal vaccine program (the comparison will be done with either within same breeder flock or breeder flock with similar age range; or alternatively compared to the total hatchability for the test day; or hatchability from previous week at the same hatchery).
The final report will summarize the data, including the hen flock(s) number from where the eggs originated.
