A plasmid encoding a fusion protein interlinked by thrombin recognition sequence between glutathione S-transferase and Japanese quail ovalbumin (without 40 amino acid residues from the 5'-end of the ORF) has been constructed, employing the expression system pGEX-2T. The deglycosylated fusion protein (64 kDa) was purified by affinity chromatography on glutathione agarose beads, analyzed by SDS-polyacrylamide gel electrophoresis, immunochemically detected with antiserum raised against Japanese quail ovalbumin and tested for its stability.

Pseudomonas aeruginosa (P. aeruginosa) is a major pathogen associated conditions like septicaemia, respiratory disorders, and diarrhoea in poultry, particularly in Japanese quail (Coturnix japonica). The infection causes huge economical losses due to its high transmissibility, mortality and zoonotic potential.

A triad of enzymatic antioxidants viz., catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx) constitutes a first line of defence against any redox imbalances in the semen. Cryopreservation enabling long term storage of semen also prompts generation of surplus reactive oxygen species (ROS) in the cells with waned antioxidants, hampering the full exploitation of this process.

Japanese quails () are sensitive to zinc (Zn) deficiency, a mineral essential for growth, development, and bone health. This study evaluated the effects of different levels of Zn in the diet on zootechnical performance, organ and carcass weight, and tibial breakage resistance in quails from 1 to 42 days of age. A 5 × 2 factorial design was used, consisting of five Zn levels (30, 60, 90, 120, and 150 mg/kg) and two thermal environments (thermal comfort and heat stress), with five replicates of 10 birds per treatment.

This study evaluated the impact of replacing inorganic mineral sources of Cu, Zn, and Se with chelated organic minerals (OM) on performance, nutrient and mineral utilization rates, and intestinal morphometry in growing Japanese quails (). A total of 150 nine-day-old quails were randomly assigned to receive one of the following diets over 4 weeks: CTRL (100% inorganic minerals), OM33 (replacement of 33% inorganic minerals), OM67 (replacement of 67% inorganic minerals), and OM100 (100% organic minerals). Quails fed the OM67 diet exhibited higher ( < 0.

The aim of the study was to identify polymorphisms in the ovalbumin gene - SERPINB14 gene and evaluate their effect on hatchability traits and egg quality changes during storage in two strains of Japanese quails: meat-type (F33) and laying-type (S22). To individually determine hatchability traits for each female, eggs were collected and incubated. To determine egg quality traits, 10 eggs were collected from each female and stored for 14 weeks.
