Abstract
The potential of in ovo boron (B) or Na aluminosilicate (SA) administration to alter embryonic development and mineralization in the turkey was evaluated. At 15 d of embryogenesis, 150 μl of B (500 or 1000 ppm), SA (500 or 1000 ppm) or vehicle (8500 ppm NaCl) was injected into the air space of fertile turkey eggs (n=60/trt). At 26 d of embryogenesis and at hatch, random samples of blood and tibiae were obtained. In ovo administration of B or SA increased (P≤0.05) embryonic weights, tibial length, and bone ash. Histological analysis of embryonic tibiae revealed a decrease (P≤0.05) in growth plate length associated with B or SA administration. These data suggest that a single in ovo administration of boron or SA significantly influences embryonic growth and mineralization in the turkey.
