Laying Quail

This study aimed to evaluate the administration of Lactobacillus plantarum AKK-30 and Saccharomyces cerevisiae B-18 as probiotics in reducing cholesterol of blood, egg, and meat and also the production performance of laying quail (Coturnix coturnix Japonica). A number of 600 birds of the twenty one-day-old quails were distributed in a completely randomized design with 5 treatments and 6 replications (initial BW= 101.35 ± 1.64 g). Treatments were as follows: A = negative control (basal diet without probiotic), B = 1% of L. plantarum AKK-30 (107 cfu/g), C = 1% of S. cerevisiae B-18 (106 cfu/g), D = 1% of a probiotic consortium, E = positive control (commercial probiotic). Parameters observed were blood biochemistry profiles, product quality, and production performance. The results revealed that administration of 1% S. cerevisiae (C) resulted the lowest cholesterol in blood (101.75 mg/dL) and egg (9.44 mg/g) and while administration of 1% L. plantarum(B) increased meat protein and decreased fat content (P<0.05). Level of blood triglycerides, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) were not different among treatments. Probiotic treatments did not affect the growth performance, quail day production (QDP), feed conversion ratio (FCR) and egg uniformity. However, probiotic increased diameter of egg yolk (P<0.05). It was concluded that administration of single probiotic L. plantarum AKK-30 or S. cerevisiae B-18 improves the quality of laying quail products.

Salinity Levels

The objective of this study was to evaluate the influence of water salinity and ambient temperature on the physiological variables and the quality of Japanese quail eggs (Coturnix coturnix japonica) in the laying phase. The quails received water with increasing levels of salinity (1.5, 3.0, 4.5 and 6.0 dS m-1) and were kept in climatic chambers under two different temperatures (24ºC and 32ºC). The design used was completely randomised, with a 2 x 4 factorial arrangement (temperatures and salinity levels), with six replicates of eight birds each. Data were submitted for analysis of variance and the means were compared by the Tukey test at 5%. There was no influence (P > 0.05) of water salinity levels on the physiological variables nor on the quality of the birds’ eggs. At 32oC there was an increase (P < 0.05) in respiratory rate, cloacal and body surface temperature of the birds, and a slight reduction (P < 0.05) in the weight of eggs, shells, and percentage of shell. For laying quails, water with salinity levels of up to 6.0 dSm-1 can be used and the birds can be raised in an environment with temperatures up to 32ºC.

Purpose: The aim is to study the effects of stocking density on the performance characteristics, egg quality, and nutrient composition of the eggs of Japanese quails (Coturnix coturnix japonica). Study Design: Completely Randomized Design (CRD). Subjects and Methods: Two hundred and ninety-six (296) day-old sexed Japanese quails assigned to four different stocking densities (treatments) with four replicates conducted in the rainy season. The groups (I to IV) contained 11, 16, 21, and 26 quails in the approximate sex ratio of 1:1 (male: female) with stock densities 252.20 cm2, 173.43 cm2, 132.10 cm2, and 106.73 cm2/quail respectively. Standard procedures were adopted in data generation, collation and analyses. Results: The results showed significant differences (p < 0.05) in weight gain, hen-day production, hen-housed production, total egg /hen, external and internal egg parameters across the treatments. The lowest feed conversion ratio (FCR) of 2.38 % and lowest mortality (2.27 %) were obtained from group one and compared with those in groups two and three. The highest mortality rate was observed in group IV (12.50 %). The proximate analysis and mineral composition of the eggs recorded the highest values from group I which was also compared with the rest of the groups. Conclusion: It was concluded that 173.43 cm2 and 132.10 cm2/quail bird compared well with the standard (252.20 cm2/quail bird) and hence could still be adopted in quail farming without compromising their welfare and performance.

This study aims to determine the effect of laser puncture shooting on the reproductive acupuncture points of Japanese quail (Coturnix coturnix japonica) egg quantity (egg production) and internal egg quality (Haugh unit, yolk index, and yolk colour). This research was conducted for 30 days using a sample of Japanese quail aged 4 weeks because for the first 2 weeks, the quail did not produce and it was in production in the last 2 weeks. There were 4 treatments and 25 replications each. So, there were a total of 100 quails. Laser puncture shooting was carried out at 3-day intervals at the Ova point and 6-day intervals at Hu Men, Bei Ji, and Wei Gen points. So, on the first day, laser puncture shooting was carried out at 4 points, on the 4th day, only at 1 point, and then, on the 7th day, it returned to 4 points. And so, it was carried out for 4 weeks. T0 (−) was considered as a negative control because quails are not given laser puncture shooting; T0 (+) was considered as a positive control because quails are treated with laser puncture shooting which is deactivated or a dose of 0 Joule; T1 was a group treated with laser puncture shooting at a dose of 0.2 Joule, and T2 was a group treated with laser puncture shooting at a dose of 0.5 Joule. Then, the research results were analyzed using Analysis of Variance and followed by Duncan’s Multiple Range Test. Laser puncture shooting at the reproductive acupuncture point of Japanese quail (Coturnix coturnix japonica) can increase the quantity of eggs ( p < 0.05 ). While the results of the egg internal quality in the form of the Haugh unit value and the yolk index increased ( p < 0.05 ), the value of the yolk colour did not change compared to the control ( p > 0.05 ). Laser puncture shooting at the reproductive acupuncture point of Japanese quail (Coturnix coturnix japonica) can increase egg quantity (egg production) and internal egg quality (Haugh unit and yolk index) with the best dose of 0.5 Joule.
