UNASSIGNED: This trial was conducted to investigate the effect of @entity369 ( @entity534 ), @entity1889 ( @entity27653 ) and @entity534  +  @entity27653 administered in ovo on growth performance, digestive organs and intestinal morphology in broiler @entity1573 . On day 14 of incubation, 400 fertile eggs were randomly allotted to five experimental treatments through injection in the amniotic fluid including: (i) control (none injected), (ii) sham (0.5  ml of 0.5% saline), (iii) @entity534 (35  mg/egg), (iv) @entity27653 (25  mg/egg) and (v) @entity534  +  @entity27653 (35  +  25  mg/egg). After hatching, chicks were given a commercial @entity4336 -soya bean diet up to 42  days of age. Daily feed intake (FI) and body weight (BW) of chicks were measured during different periods of the trial. Digestive organs were measured for their relative weight and intestinal length on days 11 and 42 of age. Intestinal morphometric traits were evaluated on day 11 of the experiment. Supplementing @entity3534 affected the performance of broiler chicks as @entity27653 significantly increased FI and BW across starter, grower and finisher periods compared with sham and control (p  <  0.05). Furthermore, @entity534  +  @entity27653 injection increased jejunal weight compared with control on day 42 (p  <  0.05). Moreover, @entity534 inclusion led to the greatest villus height and crypt depth among treatments in duodenum (p  >  0.05); however, @entity3689 supplemented groups had lower villus height than control in jejunum (p  <  0.05). Negative correlations found between digestive organs related to day 11 of age containing pancreas (r  =  -0.484; p  =  0.030), duodenal (r  =  -0.577; p  =  0.007) as well as ileal lengths (r  =  -0.471; p  =  0.035) and FI of entire period. Otherwise, positive relationships were observed between duodenum (r  =  0.580; p  =  0.007) and ileum (r  =  0.582; p  =  0.007) weights on day 42 and FI of @entity1573 across the entire phase. In conclusion, @entity534 and particularly @entity27653 injection into amnion can improve FI and post-hatch growth performance of @entity1573 which may be mediated by the development of digestive organs.

Effect of XXXX and @entity1889 administered in ovo on digestive organ developments and subsequent growth performance of broiler @entity1573 .
