“…However, Bursa% difference was non-significant among the birds of genetic lines as well as generations. Similar findings were reported by Kankova et al (2019) who reported no differences among low weight gain line (LG) and High weight gain line (HG) regarding the relative weight of Bursa of Fabricius in Japanese quail. Similarly, in chicken Cheema et al (2003) also suggest no line and age differences in the relative weight of bursa among commercial broiler chicken and random breed control line.…”

“…These findings are in harmony with the findings of El-Nagar et al ( 2016) who reported decreasing antibody titer against ND vaccine in respective 3 generations of Japanese quails selected for higher 4 th -week bodyweight resulting in lower resistance to Newcastle disease. Similarly, in another study (Kankova et al 2019) lower concentration of plasma antibodies was in higher weight gain (HG) lines as compared to low weight gain (LG) lines of Japanese quail. Koenen et al (2002) also observed weaker long-term IgG response in broiler chickens as compared to layer types.…”

The present study was aimed to evaluate the growth performance and immune response of three genetic lines of Japanese quails. These lines i.e., selected for 4-week body-weight group (WBS), selected for egg number (EBS), and random-bred control (RBC), were selected for three consecutive generations from a base population of 1125 quails. In total, 2700 four-week-old quails from three selected groups were slaughtered in total of four generations (G0 to G3). Effects of selection and generations as well as their interactions were assessed for growth performance and immune response by applying a two-way analysis of variance. Significant means were compared with Duncan's Multiple Range Test. The statistical analysis showed a significant effect of selection and generations on most of the growth and immune response parameters. WBS in G3 presented significantly higher values of body weight, weight gain, and FCR than RBC and EBS. FCR was better in WBS during G3 than those of EBS and RBC. However, Livability% was highest in RBC while the lowest was noted in G3 of WBS line. Thymus% and spleen% were higher in EBS as compared to RBC and WBS. RBC presented a better B/S ratio and ND titer than those of EBS and WBS. The decreasing trend of ND titer in both lines of WBS and EBS as compared to RBC suggested a decrease in New Castle disease resistance in progressive generations of selection. It was concluded that selection for body weight and egg number has a positive impact on respective traits but negatively affects the immunity in later generations.

Our work is devoted to the study of the immune response of the quail to two strains of antigens. We used gram-negative Escherichia coli and gram-positive Staphylococcus aureus. The choice of these types of pathogens is dictated by several reasons. Pathogenic strains of these microorganisms often cause poultry diseases, they are widespread in the environment, are representatives of the normal microflora of animals, belong to two different microorganism groups according to the Gram staining.The state of the immune system (immune status) changes under the influence of many factors, including during immunization. There are various methods for the study of humoral factors of immunity. When studying non-specific immunity factors, they use the method of determining the bactericidal activity of blood plasma. The main specific humoral factor is antibodies of various classes. There are methods to detect and determin the amount of antibodies in plasma or serum. These are agglutination, precipitation, neutralization and other serological reactions. The detection of antibodies is the most informative method of assessing immunity. Therefore, serological reactions are widely used to assess the quality of the immune response to vaccines.The objective of the study was to carry out hyperimmunization of quail with two types of bacteria (E. coli and S. aureus) and to study the nature of changes in humoral immunity factors. A suspension of inactivated bacteria was administered intramuscularly four times with an interval of 7 days. To study the immune response, we used the agglutination reaction on glass, which allowed us to identify antibodies and determine their titer. The second indicator is the change in the bactericidal properties of blood plasma as a result of immunization of quail. Most often, the agglutination reaction on glass is used only to detect antibodies. According to the results of our studies, this reaction also allows you to determine the amount of immunoglobulins. The number of antibodies in non-immune birds did not exceed 3log2. After hyperimmunization, the number of antibodies increased. In reaction with Escherichia coli, antibody titers reached to 8 log2, and with staphylococcus -9 log2. Studies of the bactericidal activity of quail blood plasma gave similar results. We incubated the studied blood plasma and culture of microorganisms at a temperature of + 37° C, and then the mixture was ulated on solid nutrient media. The result was taken into account by the presence of bacterial growth on the agar surface. The blood plasma of a non-immune bird did not cause the destruction of bacteria. Blood plasma obtained from an immunized bird completely lysed Staphylococcus aureus and E. coli almost completely. Our results indicate a intensive immune response of the quail organism to bacterial antigens.
