Effect of Dietary L-ascorbic Acid (L-AA) on Production Performance, Egg Quality Traits and Fertility in Japanese Quail (Coturnix japonica) at Low Ambient Temperature

Five weeks old layer Japanese quail (Coturnix coturnix japonica) birds (180 nos) were randomly distributed into 4 dietary groups with 3 replicates each for 98 days to study the effect of dietary inclusion of acid ensiled fish waste silage on the production performance, egg quality, feed cost, and serum biochemical profile. Fish meal in control diet was replaced by supplementing fish silage at 3%, 6% and 12% of the diet. Significant increase in egg production (p>0.05) and the lowest feed conversion ratio were recorded when birds were fed with 3% silage. But the egg production or feed conversion ratio was not adversely affected by 6% or 12% inclusion of fish silage. Egg quality attributes like weight, shape index, Haugh score, albumen index or yolk index did not differ significantly with the increasing content of silage in the feed. The yolk concentration increased significantly (p>0.05) with increase in fish silage in the diet. The concentration of serum biochemical constituents (total protein, albumen, globulin, cholesterol, triglyceride, alkaline phosphatase, urea and creatinine concentration) did not vary significantly (p>0.05) among the treatments. Serum glucose concentration was the highest in birds fed with 3% fish silage. Lowest cost of feed/kg egg mass was obtained by inclusion of 3% of fish silage in the diet. It was concluded that acid ensilage from freshwater fish waste can replace fishmeal in layer Japanese quail diets without affecting the production of birds besides resulting in reduction of feed cost.

Quality Traits

In the last years Japanese quail (Conturnix coturnix japonica) is becoming more popular as a source of meat and eggs. Information on egg quality characteristics has been limited mostly to chicken eggs. The aim of this paper is to enhance the knowledge on the quality of quail eggs. In this study external and internal quality traits of quail eggs from three different commercial farms will be presented. For egg mass, shape index, shell thickness, shell mass no significant difference was found between farms. For yolk colour, yolk and albumen mass, statistically significant differences were found between the three farms. The difference in shell breaking strength between farms A and B was not significant and significant differences were found between eggs from farm C. Yolk, albumen and shell percentage were in the same relation as the mass of these parameters. The worst albumen quality was recorded in eggs from farm A. The parameters yolk colour, Haugh Unit and egg proportions (albumen, yolk and shell) do not differ between chicken and quail eggs. On the other hand, parameters which differ are egg mass (about five times smaller at quail eggs), shape index, shell breaking strength and shell thickness, which was to be expected. The external and internal egg quality traits of quail eggs from three farms in Serbia do not differ from the results of quality traits from other countries. On the other hand, this investigation contributes the development of science, because it includes some parameters, which have so far not been published in literature by other researchers from this area.

Egg Number

Background: Egg production efficiency is typically measured through age and body weight at sexual maturity, egg number and egg weight during certain production periods. Increased egg weight and number of eggs are the primary purpose of the laying bird breeding programmes. Partial period analysis enhances selection process as the variations occurring throughout the bird’s productive life are identified and helps in the selection decisions. The current study aimed to study the genetic parameters such as heritability, phenotypic and genetic correlations to improve egg production performance and egg quality traits in Japanese quail reared at the Central Avian Research Institute (CARI).Methods: In present investigation, data recording was carried out from the Japanese quail population at experimental quail farm, CARI during 2019-2020. The individual mating was conducted between 180 sires and 180 dams of three varieties of Japanese quails were randomly selected from the base populations to develop first generation of experimental population. The hatched chicks were wing banded and the pedigree details recorded. For economic traits such as egg production and egg quality estimation, 40 sires and 40 dams were selected and parameters were evaluated. Result: In this present investigation, egg number from 10-16th week of age exhibited moderate to high heritable values. Egg weight was estimated moderate heritability traits. In egg quality traits, all values were moderate to high heritable values except yolk density in all the three varieties.
