The effects of <i>in ovo</i> injected with sodium borate on hatching performance and small intestine morphology in broiler chicks

Abstract The objective of this study was to investigate the effects in ovo injection sodium borate on hatching power, chick weight, length fertile broiler eggs. A total 256 eggs were incubated study. On Day 18 incubation, two groups injected with 0.1 mL 0.5 mg and 1 dissolved saline, used as sham control (injected saline) uninjected control. Hatching power apparently increased ( P ≤ 0.05) by (0.5 mg) rather than (1 group. While there no significant difference between terms weights, a found group B other experimental &lt; 0.05). In had positive effect villus length, crypt width, absorption surface (HASA), number proliferating cell nuclear antigen cells.
