A study was conducted to evaluate the influence of automated injections on poult viability after hatching. The study was completed as a replica of previous large-scale commercial investigations, wherein eggs were injected at 25 days of incubation with D-biotin in saline solution and saline solution alone in order to compare hatchability with that of uninjected eggs. Each of the three treatments utilized 240 embryonated eggs. After hatching, 100 female poults from each treatment were place in cartons and shipped 350 miles to the location of the viability study. Researchers placed poults in each treatment in separate floor pens and gave them free access to a 28% protein diet and water. At 2 wk of age, poults in each treatment were assigned of four replicate pens, with twenty-four poults of equal average body weight per pen. Poult livability and growth did not differ at 9 to 2 wk of age and 2 to 9 wk of age between injected and uninjected eggs.

Key Words: Automated egg injections • embryonated eggs • hatched turkey poults • viability
