The Effects of In-Ovo Injected D-Glucose Monohydrate and Ascorbic Acid on Hatchability, Body Weight and Early Post-Hatch Performance of Geese

Abstract

The aim of the current study was to determine the impact of in-ovo injected D-Glucose monohydrate and ascorbic acid on hatchability, body weight and early post-hatch performance of geese. The 360 eggs from a 50-wk-old Embden crossbred breeder flock were set in a single-stage incubator with 4 treatments. The experimental treatments were: (1) non-injected Control, (2) Dextrose 24 mg / 0.5 mL, (3) Vitamin C 10 mg / 0.1 mL (4) Dextrose 24 mg / 0.5 mL + Vitamin C 10 mg / 0.1 mL. At 11 and 18 d of incubation, the eggs were injected into the albumen manually under sterile conditions. At 25 d of incubation, the same amount of the agents was injected into the yolk sac of the fertile eggs with the same procedure. The hatchability of the Control and Dextrose + Vitamin C groups were statistically different (P < 0.05). Although there was a statistically insignificant difference, the highest value was recorded in the Dextrose + Vitamin C group on the 25th-day. The hatchling weights were only influenced by the agents. The 25th-day Dextrose + Vitamin C treatment had the greatest values at body weights at hatch. There were no statistical differences by the injection days, agents and interactions regarding body weights at 7th-day post-hatch. In addition, there was no significant impact of different injection sites on both hatchling weight and, body weights of post-hatch 7th-day. It is suggested that the in-ovo injection should administrate on the 25th day of incubation into the yolk sac in goose eggs with a mixture of D-Glucose monohydrate and ascorbic acid.

Investigation of the effects of in ovo taurine injection on hatching characteristics and stress reduction potential

“…In ovo administration of taurine to broiler breeder eggs in the early embryonic period significantly increased the number of muscle cells and nuclei, muscle fibre diameter and proliferating cell nuclear antigen gene expression in the muscles (Zielinska et al., 2012). Some substrates and their combinations (carbohydrates, vitamin C and vitamin D3) have been tested via the in ovo route to determine how they affect the hatchability of birds (Baykalir et al., 2021; Salmanzadeh, 2012; Zhu et al., 2019). However, in one study, the in ovo administration of corticosteroids on embryonic day 7 resulted in a 35% decline in hatchability (Heiblum et al., 2001).…”

Effects of methionine and/or disaccharide injected in the amnion of geese on post-hatching pectoral muscle and small intestine development, glycogen reserves, jejunum morphology, and digestive enzymes activities

“…The geese are seasonal producers, eggs of geese are mainly used for reproduction and research purposes ( Tserveni-Goussi and Fortomaris, 2011 ). Therefore, the improvement of gosling quality during post-hatching stages in commercial geese farming becomes critical ( Baykalir et al, 2021 ).…”
