Abstract:

A study was conducted in order to estimate the sodium requirements of Japanese laying quail (Coturnix coturnix japonica). In this study, we used 280 Japanese quails at 128 days of age, with an average weight of 9 ± 5.2 g, and an egg production rate of 82.3 ± 0.94%. An experimental design methodology was employed, completely randomized with five treatments and seven replications. Each replicate consisted of eight quails, with a total of thirty-five experimental units. The experimental diets were based on corn and soybean meal, and contained five different levels of sodium (0.08%, 0.12%, 0.16%,

Abstract:

Egg quality traits in quail breeders depend on various factors which may influence embryo survival during incubation, affecting the chicks' production and quality. The current study aimed to determine the effect of the laying period on the external and internal quality of the egg, the chemical composition of albumen, yolk, and eggshell as well as the reproductive parameters of quail breeders. A total of 450 quails (Coturnix japonica) obtained from the same hatchery, were reared in a battery cage with a sex ratio of 1 male to 3 females.

Abstract:

Japanese quail are resilient birds that thrive in compact cages and are relatively affordable to raise. They are small, with adult quails weighing between 150 to 200 grams. They reach maturity in about six weeks and begin laying eggs at around 50 days of age. Under optimal care, hens can produce up to 200 eggs during their first year. Though they are susceptible to common poultry diseases, they are generally resistant to most. The lifespan of a quail is typically around 2 to 2.5 years. Female quails have light tan feathers with black speckles on the throat and upper chest, while males are char

ABSTRACT This study aims to evaluate effects of inclusion of moringa in Japanese quail diets on laying performance, egg quality, blood parameters, serum biochemical profile, and behavior. One hundred and forty-four Japanese quails, approximately 35-d-old, were distributed in a completely randomized design with four treatments and six replications. Treatments were diet inclusion of 0, 2, 4 and 6% of dried and ground moringa leaves. The inclusion of moringa in diets reduces the quadratic feed intake up to the level of 1.20%, increases weight of eggs with a quadratic behavior up to 3.80%, and lin

Fertility of cryopreserved ovarian tissue from immature chickens and Japanese quail has been recovered by transplantation. This is of special importance for non-mammalian vertebrates in which cryopreservation and in vitro maturation of oocytes are challenging because their oogenesis is characterised by vitellogenesis. This study tested whether fertility of adult quail ovarian tissue could be recovered by transplantation. Ovaries were isolated from mature Japanese quail hens, trimmed, cut into 3- to 4-mm2 pieces and transplanted into ovariectomised, week-old chicks. Recipients were administered

Abstract:

The primary cause of injuries and inflammation of the reproductive system in female quails in industrial quail farming is the process of egg formation and its passage through the oviduct. With technological injuries females aged from 42 to 55 days are involved into the risk zone, whose weight of laid eggs ranges from 11,6 to 13,7 g. In previous morphological and histological studies, the following patterns of development of the organs of the reproductive system of quails under conditions of intensive technology have been established.

Abstract:

In Côte d’Ivoire, the quail breeding is confronted with the lack of food specific to the species. Thus, in the south-east of this country, an experimental study was conducted at the ISMOREL farm in the sub-prefecture of Adiaké. This study, which aims to improve the productivity of day-to-day farms, focused on the grain size of the feed. From grower (GD) and layer (LD) diets, 5 experimental diets have been manufactured. There are: LD 5 with a particle size of 5 mm, LD 3 and GD 3 with a particle size of 3 mm as well as LD 2 and GD 2 with a particle size of 2 mm. The growth par

Abstract:

The article presents the results of studies on the performance of Japanese quails when using different technological equipment in the JSC “Soligorskaya poultry factory” of the Soligorsky district. It was found that the use of KVI – 4N and OKP – 6 cage equipment contributed to the high performance of quails while reducing feed costs. When using the KVI – 4N and OKP – 6 cage equipment, the profitability of 14.5 – 16.1% was obtained within the trial. Based on this, it can be concluded that rearing quails in KVI – 4N and OKP – 6 cage batteries is economically profitable. This approves using this b

Using additives can reduce the negative effects of aging on factors affecting profitability, such as the availability of nutrients, production, and egg quality. Maca is an herbaceous plant rich in protein, crude oil, essential acids, and pharmacological compounds. Maca has positive effects on different health parameters. In this study, the effect of adding Maca powder to the diets of young and old laying quails at the end of the 10-week trial was investigated.
