Effect of in ovo feeding of butyric acid on hatchability,performance and small intestinal morphology of Turkey poults [In ovo bütirik asit beslemesinin hindilerde yumurtadan çıkma,performans ve ince barsak morfolojisi üzerine etkileri]

The aim of present study was to investigate effect of in ovo administration of butyric acid on hatchability,performance,and small intestinal morphology of turkey poults. fertilized eggs were subjected to injections with butyric acid (10 mg,20 mg and 30mg dissolved in 0.5 ml of deionized water) on the d 7 of incubation. hatching traits,body weight gain (bwg),feed intake,and feed conversion ratio (fcr) were determined during experiment.small intestinal morphology included villus height (vh),crypt depth (cd),and villus width (vw) were measured at hatch and the end of each rearing periods. finally,the results of the present study indicate that the weight of newly-hatched poults was significantly greater when butyric acid were administrated,in comparison with control groups.but,in ovo feeding (iof) caused lower hatchability than in control group (not-injection eggs) (p<0.01). poults from iof showed better weight gain and fcr (0-42 day of age),when compared to poults hatched from control (p<0.01). the iofb significantly increased vh for duodenum,jejunum and ileum at both hatch and starter period. it was concluded that iofb may affect vh of intestine at hatch and starter (post-hatch) period in turkeys. also,iofb can improve performances. © 2015,veteriner fakultesi dergisi. all rights reserved.
