ABSTRACT
This study was designed to determine the effects of in-ovo sugarcane vinegar (SV) solution to Sudani duck’s eggs with different concentrations on body weight at hatch, hemato-biochemical changes and subsequent performance of newly-hatched ducklings. A total of 1560 fertile eggs used in the current experiment were obtained from Sudani ducks flocks of 33 weeks of age. The eggs were randomly distributed into of five different SV solution concentrates; the first (1st) group without any treatment and served as a control (C), the 2nd group was dipped into distilled water as a vehicle or positive control (SV1). The 3rd group (SV2), the 4th group (SV3) and the 5th (SV4) group were dipped in 0.05, 0.10 and 0.15% of SV solutions for 3 minutes, respectively, at four-time of eggs dipping: at day 10th (T10), day 17th (T17), day 24th (T24) and day 31st of incubation (T31) totaling twenty groups with three replicates of (26 eggs of each). The results showed that ducklings from eggs dipped at SV had significant (P<0.05) better body weight than ducklings hatched from the control and sham groups. The heterophil to lymphocytes ratio (H/L) was significantly (P≤0.01) lower for Sudani ducklings in SV4- group × T24th than those of the other experimental groups. Furthermore, concentrations of serum total protein and their fractions (albumin and globulin) and all lipid profile were insignificant affects by in-ovo different SV solutions, times of eggs dipping and their interaction. The best values of body weight gain, feed conversion ratio and performance index were recorded in that group dipping eggs at 0.05% SV followed by groups dipping at 0.15 or 0.10 % SV throughout the experimental period. According to the results, it can be concluded that in-ovo dipping in 0.0.5% of SV solution, especially on day 10th of incubation has a positive effect on the subsequent performance of newly-hatched ducklings during initial rearing phase.
