摘要

Background:Among various feed additives currently used in poultry nutrition,an important role is played by bioactive substances,including prebiotics.The beneficial effect of these bioactive substances on the gastrointestinal tract and immune system give rise to improvements in broiler health and performance nutrition,thus increasing the productivity of these birds.An innovative method for introducing bioactive substances into chickens is the in ovo injection into eggs intended for hatching.The aim of the study was to evaluate the development of histomorphological parameters of the duodenum and productivity in chickens injected in ovo with the prebiotic DiNovo(R) (extract of Laminaria species of seaweed,BioAtlantis Ltd.,Ireland) on d 12 of incubation,under large-scale,high density poultry production conditions.Results:There was no significant impact of the injection of DiNovo(R) prebiotic on the production parameters of broiler chickens (body weight,FCR,EBI and mortality) obtained on d 42 of rearing.No significant impact of the DiNovo(R) injection on the duodenum weight and length was observed,as well as on the CSA,diameter and muscular layer thickness of the duodenum.The in ovo injection of DiNovo(R) significantly increased the width of the duodenal villi (P ＜ 0.05) and crypt depth (P ＜ 0.01) of chickens on d 21 of rearing.Other histomorphological parameters of duodenal villi at d 42 of chickens rearing such as:the height,width,and cross section area of villi were significantly greater in chickens from the control group compared to those from the DiNovo(R) group (P ＜ 0.05 and P ＜ 0.01).Conclusions:In conclusion,this study demonstrates that injection of DiNovo(R) prebiotic into the air chamber of egg significantly influences the histomorphological parameters on d 21 of rearing without negatively affecting productivity in chickens at the end of rearing.
