This study aimed to determine the efficacy of lactic acid bacteria probiotics containing Lactobacillus acidophilus and Lactococcus lactis on nutrient consumption and egg weight of Japanese quail. A total of 120 females Japanese quails comprised four treatments and six replications. T0, T1, T2, and T3 treatment groups were administered L. acidophilus and L. lactis with concentrations of 0, 1, 2, and 3 mL/liter of drinking water. Consumption data were collected weekly, and egg weight data were collected daily during treatment. The data obtained were then analyzed statistically using analysis of variance (ANOVA) and continued with the Duncan multiple range test (p < 0.05). The results of this study showed that probiotics in drinking water reported significant differences (p < 0.05) compared between treatments (T1, T2, and T3) to reduce nutrient intake of organic matter, crude protein, crude fat, crude fiber and increase egg weight of quail. It can be concluded that the combination of L. acidophilus and L. lactis can reduce nutrient consumption but can increase the egg weight of Japanese quail.

Sex identification of Sun Conures (Aratinga solstitialis) is crucial for breeding and preservation, as well as increasing sun conure populations. These birds are sexually monomorphic. Therefore, Determination between male and female carried out by their morphology examination. The Polymerase Chain Reaction (PCR) method, utilizing molecular-based technology, was employed to determine the sex of Aratinga solstitialis in this study. The P2 and P8 primers were utilized in this method, which has been deemed suitable and accurate for sex identification through calamus samples. The research focused on two 28-month-old Aratinga solstitialis birds. Calamus samples were collected and subjected to PCR amplification using the extracted calamus. The resulting PCR products were then visualized using electrophoresis with a 1% agarose gel. In the electrophoresis photo, the presence of two bands indicated a female specimen, whereas a single band indicated a male specimen. The result of the gel electrophoresis research showed that both of the Aratinga solstitialis were male with one band of each bird on ranged from 300-400 base pairs. The result show that the Polymerase Chain Reaction method in terms for sex identification on monomorphic birds, especially Aratinga solstitialis birds is very effective to differentiate the sex of young birds and the adults.

This study aimed to determine the effect of Bifidobacterium sp. and Guazuma ulmifolia leaf extract on Japanese quail egg production, including egg mass, haugh unit (HU), and egg yolk colour. A total of 96 quails were in the early stages of production, which were randomized into four treatments and six replications. The treatments were (T0) without Bifidobacterium sp. and G. ulmifolia leaf extract, (T1) 0.2% Bifidobacterium sp., (T2) 0.2% G. ulmifolia leaf extract, and (T3) 0.2% Bifidobacterium sp. + 0.2% G. ulmifolia leaf extract. Egg mass data was collected in the third and fourth week of the treatment period, while the HU data and egg yolk colour were carried out on the last week of the treatment period. The treatment groups showed significant differences in egg mass. Groups T2 and T3 showed significant differences in egg yolk colour. The combination of feed additives can increase the value of HU but not significantly (p>0.05). In conclusion, the combination of 0.2% Bifidobacterium sp. and 0.2% G. ulmifolia leaf extract in drinking water can produce the highest egg quality.

The purpose of this study was to determine the effect of adding the concentration of turmeric flour and fish oil to the quail formula feed. This research is an experimental study using the factorial method. This experiment used 96 quail (Cortunix cortunix japonica), which were randomized into 6 treatments with 4 replications. Quails were divided into 6 groups and treated with different concentrations of turmeric flour and fish oil in each feed formula. The effects of different formula feeds were observed on changes in egg production and organoleptic changes. Egg production data were taken every day from week 3 to week 4 during the treatment period. The data taken is called Quail Day Production (QDP%). The organoleptic data of eggs were taken at the 3rd week of treatment and the preference test was carried out by 40 panelists on the aroma, taste and level of preference of quail eggs after being boiled. The addition of 0.3% turmeric flour significantly affected egg production but its combination with fish oil did not affect egg production. The combination of the concentration of turmeric flour and fish oil does not change the aroma of the eggs, but changes the taste of the eggs.
