The Effect of High-Level Dietary Supplementation with Different Zinc Sources on Performance, Eggshell Quality and Bone Characteristics in Layer Quails

Abstract

The aim of this study was to investigate the effects of dietary supplementation with high levels of inorganic, organic or nano sources of two high-level zinc diets (200 and 300 mg/kg) on performance, eggshell quality and mineral content of bone in layer quails. The experiment had a 2×3 factorial arrangement of treatments. Egg production and the zinc content of tibia were significantly increased in the present experiment. Compared with zinc oxide supplementation, zinc-glycine supplementation increased zinc concentration in the tibia. The interactions between the sources and levels of zinc were a significant effect on egg production, eggshell breaking strength, eggshell weight and tibia zinc level. The highest eggshell breaking strength and eggshell weight were observed in the group was fed with diet including zinc-glycine at 300 mg/kg. These results suggested that zinc-glycine supplementation positively effects eggshell quality parameters and tibia zinc concentration when compared with other sources used in this experiment. Additionally, the supplementation layer quail diets with zinc-glycine rather than nanoparticulate sources of zinc could be recommended for optimum performance.

Applications of nanoparticles of zinc oxide on productive performance of laying hens

“…Moreover, zinc can play an important role for the poultry in many aspects such as antioxidant, growth performance, protein synthesis and nutrient metabolism (Salim et al, 2008). Zinc is also necessary for bone development, production, enzyme structure and egg shell formation (Tüzün et al, 2018). Furthermore, Nano-ZnO reduced yolk lipids by decreasing biosynthesis and increasing lipid degradation (Zhao et al, 2016).…”

“…Moreover, zinc can play an important role for the animals in many aspects such as antioxidant, growth performance, glandular development, protein synthesis, carbohydrate metabolism, nutrition, production performance and function as a cofactor in more than 300 metalloenzymes (Salim et al 2008). It is also necessary for bone development, growth, enzyme structure and egg shell formation (Tüzün et al, 2018).

Influence of the Zinc and Fibre Addition in the Diet on Biomechanical Bone Properties in Weaned Piglets

“…Świąkiewicz and Koreleski [ 25 ] found that bone biomechanical properties were not affected by organic zinc supplementation in laying hens. Tüzün et al [ 24 ] found no significant differences in bone strength, stiffness, or mineralisation in quails fed inorganic, organic, and nano zinc sources. Similarly, studies presented by Tomaszewska et al [ 22 , 35 ] demonstrated that the source of Zn (ZnO vs. ZnGly) in the diet did not affect the femoral mechanical parameter, cross-sectional area, and wall thickness in broilers.…”

“…Since Zn is located at sites of tissue calcification, including osteons and calcified cartilage, the bone tissue zinc levels increase as bone mineralisation increases [ 22 ]. Results of a recent study have shown that dietary supplementation of Zn increased the bone biomechanical properties [ 23 , 24 ]. Contrarily, Świątkiewicz and Koreleski [ 25 ] indicated that supplementation of Zn had no effect on the mechanical characteristics of bone.…”
