Genetic variation of the japanese quail (Coturnix Coturnix Japonica) based on biochemical polymorphism

The study aimed at characterizing the Japanese quail using biochemical markers. Blood protein polymorphism of one hundred and sixty-six (166) Japanese quails of both sexes comprising of 83 each of mottled brown and white quails were analysed using cellulose acetate paper electrophoresis. Six loci which includes hemoglobin (Hb), transferrin (Tf), albumin (Alb), carbonic anhydrase (CA), alkaline phosphatase (Alp) and esterase-1 (Es-1) were tested. All the loci tested were polymorphic with each locus having two co-dominant alleles controlling three genotypes. Allele B was predominant at Hb, Tf and Es-1 locus with frequencies 0.90, 0.55, and 0.77, respectively while Allele A was predominant at Alb and Alp locus with frequencies 0.83 and 0.58 respectively. The Allele A had generally lower frequencies than B at the CA loci having values of 0.43 - Brown, 0.38 - White and 0.40 - overall. The mean observed heterozygosity (Ho) was 0.48 with brown and white quails having Ho values of 0.47 and 0.49 respectively, and the expected heterozygosity was observed to be higher in white quails (0.39) than in the mottled brown (0.31). The genetic distance (0.0534) between white and brown quails in this study showed little genetic differentiation between the brown and the white quails. Dendogram generated from the genetic distance values indicated that the two strains had common origin.

Dietary Treatments

One hundred and eighty (180) unsexed twenty-one day-old growing Japanese quails (Coturnix coturnix japonica) were fed for 28 days with diets in which maize was replaced with cassava grit at 0, 25 and 50% with or without β-glucanase supplementation. The birds were randomly grouped into six treatments in three replicates of ten birds per replicate. Diet 1 was the control without cassava grit while diets 2 and 3 had 25 and 50% of their maize contents replaced with cassava grit respectively. Diets 4, 5 and 6 were the same as diets 1, 2 and 3 respectively but for the inclusion of β-glucanase at 100mg/kg. Feed and water were supplied ad libitum throughout the period of study. Feed intake (590.98g), weight gain (93.77g) and FCR (6.35) were significantly (p<0.05) affected by the dietary treatments. 6 Among the haematological parameters monitored RBC (4.46x10 /UI) and WBC 3 (26.52x10 /UI) were significantly (p<0.05) affected by dietary treatments. Thiocynate (2.57 mg/ml), AST (290.6 U.I/L) and ALT (33.6 U.I/L) were also significantly (p<0.05) influenced by the experimental diets. Replacement of 25 or 50% maize with cassava grit in diets of the Japanese quail diets did not have negative effect on haematology and serum biochemistry of the birds. There were however significant differences (p< 0.05) affected by the treatments while caeca length and the lungs weight were statistically similar across the treatments. Replacement of maize with cassava grit at 25 and 50% in Japanese quail diets had no negative effect on haematology, serum biochemistry and carcass characteristics of the birds.

Abstract The objective was to evaluate the use of guava extract (Psidium guajava L.) as an antioxidant additive in the diets of Japanese quails (Coturnix coturnix japonica) in laying phase and to verify the incubation parameters of eggs stored at different periods pre-incubation. The experiment was conduced at Federal University of Goias. The extract contained 2.13% ellagic acid. A four hundred and thirty-two (432) eggs of Japanese quails fed with guava extract in the diet were incubated in a completely randomized design, in a single-stage incubator. Temperature of 37°C and humidity of 65% was manteined. The eggs were distributed in 4x2 factorial design (levels of guava extract and stored pre-incubation period) with 54 replicates, each egg being considered an experimental unit. Four levels of guava extract were added in diets of the breeders (0.0%, 0.3%, 0.6% and 0.9%) and two stored pre-incubation period (three and nine days) were studied. The results were submitted to analysis of variance and Tukey test at 5% probability. To embryo diagnostic was used Fisher exact test. The eclosion percentage was not influenced by factors studied. There was a significant interaction (P < 0.05) between effects of levels of guava extract in diet and stored pre-incubation period on hatch window. The hatch window was shorter for quails from egg storage for nine days and breeders fed a 0.0% guava extract. The lower level of guava extract supplementation in diets (0.3%) of breeder promotes padronizing hatcheries time. The neonates quails from eggs storaged for nine days hatched in shorter period time in relation to quails from the eggs stored for three days. Values of the embryo diagnostic were not different (P > 0.05). It is concluded that the use of 0.3% inclusion of guava extract containing ellagic acid in layer quail diets promotes standardization of hatchery window of neonate quails.

Abstract. Sujana E, Anang A, Setiawan I, Widjastuti. 2020. The egg characteristics of malon broiler, Japanese quails and their cross. Biodiversitas 21: 889-895. Research on evaluation of the characteristics of Malon broiler and Japanese quails (Coturnix coturnix japonica) eggs and on the crossbreeding between the two has been implemented in the Quail Breeding Center, Universitas Padjadjaran, Jatinangor, Indonesia. The purpose of this research is to know and evaluate the characteristics of Malon broiler and Japanese quails eggs and the crossbreeding between the two. The research used experimental method with complete random draft consisting of 4 treatments with six repeats, with each replay unit consisting of 10 grains so that the total of incubator eggs used are 240 grains. The treatment used was the breeding or marriage of Malon broiler quail ♂ x Malon broiler quail ♀ (MM), selected Japanese quail ♂ x selected Japanese quail ♀ (JJ), Malon broiler quail ♂ x selected Japanese quail ♀ (MJ), and Japanese selected quail ♂ x Malon broiler quail ♀ (JM). Statistical analysis was conducted using GLM (General Linear Model) with test Duncan using SAS application programs. The observed parts are egg weight, egg shape or Shape Index (SI), specific gravity (SG), and eggshell thickness. The results showed a noticeable difference in those parts. Further research results showed that the best quality of egg incubator comes from the crossbreeding of Malon broiler quail ♂ x selected Japanese quail ♀(MJ), which is good for breeding quails.

The Impact

The study aims to determine the impact of dietary crude protein levels on the hematological parameters of Japanese quail from growth to ovipositor. To this end, five feeds with different crude protein levels (18, 20, 22, 24 and 26%) were supplied to 700 quails of three weeks of age. These were subdivided into six batches, including three batches of females and three batches of males for each feed group. After subjecting the quails to diets containing the different protein levels, four samples were taken at the fourth, fifth, sixth and seventh week of age. The samples taken were analyzed using an SYSMEX XN 350 automated hematological analyzer. The results of this investigation indicated that non-significant differences (P > 0.05) were observed in hematological parameters in both female and male quails. This study showed that dietary crude protein levels had no impact on the health status of Japanese quails. Keywords: Japanese quails, Crude protein, Hematological parameters.
