Effects of In-Ovo Injection of Manganese on Some Organ Weights and Lengths in Quail Hatching Eggs

Abstract

This study investigated the effects of in-ovo injection of manganese on some organ weights and length in quail hatching (Coturnix coturnix japonica) eggs. In total, 400 quail hatching eggs were randomly divided into four treatment groups of 100 eggs per treatment with four replicates of 25 eggs each. On the 14th day of incubation, eggs from group 1 were not injected (control(C)), group 2 was injected with Mn-bioplex at 20 µg per egg (Mn20), group 3 was injected with Mn-bioplex at 40 µg per egg (Mn40), and group 4 was injected with Mn-bioplex at 80 µg per egg (Mn80). There were no significant differences among treatments for chick weight, yolk sac weight, liver weight, and heart weight. The highest chick length was obtained from the C treatment. No significant differences were found in chick length among Mn treatment groups. The beak length of C treatment were lower compares with that of the Mn80 treatment group (P<0.05). But no significant differences were observed in beak length among Mn treatments groups. The leg length in C group was significantly lower than Mn40 and Mn80 treatments groups, except Mn20 treatment group (P<0.01). As a result, it can be said that injection of Mn into the hatching quail eggs causes the chick and leg lengths to decrease, and beak length to increase without affecting the weight parameters examined.

Broiler intestine DMT1 gene expression and bone characteristics, as affected by in ovo injection of different forms of manganese

“…Usind in ovo injection of Mn at different concentration (20, 40 and 80 lg per egg) in quail hatching eggs, Yıldız et al (2018), reported that compared to control (not injected), eggs treated with 40 and 80 lg of Mn, significantly increased the leg length, which is in agreement with that found on P7 of present experiment . In contrast, in ovo injection of mineral mixtures with different levels of Mn (from 0.013 to 0.039 mg per egg), did not affect tibia length in broilers (Oliveira et al 2015b;Yair et al 2015).…”
