[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for raising poultry chicks.

[0002]

2. Description of the Related Art Conventionally, for example, when a large number of broiler chickens are bred in a large-scale business, the floor surface of a large breeding house (hereinafter referred to simply as the floor surface) is made of tin strips. The tic guard (see FIGS. 8 and 9) is divided into several rings, and 1000 to 2000 birds are placed in each ring to keep the whole building bright. Then, as shown in FIG.
In the case of chicks at the beginning of breeding, that is, in the case of chicks that are new to life, the ring of the tic guard 20 has a small diameter, and as shown in FIG.

[0003]

However, in large-scale management, the number of tic guards is large, it is troublesome to adjust the wheel diameter, and it is necessary to clean the tic guards. There was a problem that the use of the tic guard was troublesome because it had to be stored in.

Therefore, an object of the present invention is to solve the above-mentioned problems of the tic guard, and by effectively utilizing the illumination without using the tic guard, as in the conventional case in a large breeding house. , For example, 1000-2
It is intended to provide a method capable of breeding poultry chicks on each floor of a breeding house by dividing them into 000 birds.

Another object of the present invention is to provide a method capable of satisfactorily raising a predetermined number of poultry broods in a large breeding house without using a tic guard.

[0006]

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a method for raising poultry chicks in a large breeding house by darkening the inside of the breeding house and illuminating the floor with a light source. The present invention is characterized in that a bright part having a predetermined diameter corresponding to the number of chicks is kept and bred for a predetermined number of days, and the chicks are grown and the diameter of the bright part is gradually increased to raise the chicks.

The poultry brood can be applied to poultry chicks such as chicken, quail, duck, sardine and ginkgo.

[0008]

[Action] Poultry chicks stay in the light area of the floor and do not go to dark areas due to their habits. The light floor is enlarged according to the growth of the chicks to make the breeding floor surface of the chicks wider.

[0009]

EXAMPLE An example of the present invention will be described below with reference to FIGS. The breeding house 1 shown in FIG. 6 has a frontage W of 9 m, a depth L of 50.4 m, and a ceiling height H of 2.5 m. The case of breeding the first broiler chicks in this breeding house 1 will be described. To do.

In FIG. 6, eight light sources, a 100 W incandescent light bulb (hereinafter, simply referred to as a light bulb) 3 in this example, are provided on the ceiling 2 in the breeding house 1 at approximately predetermined intervals through a sliderac (not shown). It is arranged so that it can be turned on. Each light bulb 3 is covered with a conical umbrella body 4 that can be opened and closed, and the diameter of the bright portion 6 with which the floor surface 5 is irradiated can be changed by the opening degree of the umbrella body 4. In addition, as shown in FIG. 5, the umbrella body 4 of this example is
An opaque fan-shaped plate 4A made of metal or the like having an appropriate rigidity is overlapped at both end edges 7A and 7B on the radius side thereof, and the light bulb 3 is covered with a large-diameter conical shape at the lower side and can be detached by an appropriate means. It is formed by holding and wearing it, and in the initial stage of breeding, the umbrella body 4 in which the end edge 7A of the fan-shaped plate 4A of FIG. 5 is overlapped to the position of the radius 8A is provided, and the small-diameter bright portion 6 shown in FIG. Board 4A
When the umbrella portion 4 in which the end edge 7A is overlapped at the position of the radius 8B is reduced by reducing the overlapped portion, the large-diameter bright portion 6 shown in FIG. 3 can be provided, and a predetermined size is provided between the radii 8A and 8B. The bright portion 6 of the can is formed.

Further, an electric heating type bruder (heat retaining device) 9 is hung from the ceiling below the light bulbs 3.
The bruder 9 may be a gas heating type.
An auxiliary light bulb 10 is attached to the lower surface side of the bruder 9 via a slidac (not shown), and the light bulb 3 of the ceiling 2 is attached.
The light is blocked so that it is blocked by the bruder 9.

The window 1 (not shown) of the breeding house 1 is closed by a light-shielding curtain (not shown), and the inside of the house is made a dark part 11 which does not allow external light to enter.

Under each light bulb 3, 1,000 chicks of the first generation are bred, but since the breeding condition is the same,
The following will be described under one light bulb 3.

Therefore, as shown in FIG. 1, the light bulb 3 and the auxiliary light bulb 10 are turned on, the floor 5 is provided with a small-diameter bright portion 6, and the brewer 9 is energized to lower the temperature inside the house from 28 ° C. Insulation is controlled so that it does not exist. In addition, as shown in FIG. 2, a proper number of feeders 12 and drinkers 13 are arranged on the floor surface 5 of the bright portion 6 in FIG. 1, and food and water are appropriately supplied to each of them.

As shown in FIG. 2, the brightness of the floor surface 5 of the bright portion 6 in FIG. 1 was 17 lux in the LA portion, 28 lux in the LB portion, 70 lux in the LC portion, and 18 lux in the LD portion. . Beginning Bina gathered in areas brighter than 18 lux and never went to the dark area 11 where no light was emitted.

The larvae of the first generation are kept up to the age of 2 days while keeping the size of the light portion 6 in FIG. 2, and the diameter of the light portion 6 of the floor 5 is R for 3 to 5 days.
Is set to 3.0 m (not shown) and the brightness of the light bulb 3 and the auxiliary light bulb 10 is adjusted with a sliderac so that the outer end of the bright portion 6 is 18 m.
I tried not to get darker than it looks.

Next, from 6 to 10 days of age, the conical shape of the umbrella body 4 is enlarged as shown in FIG. 3, and the diameter R of the bright portion 6 of the floor surface 5 is set to 6.0 m as shown in FIG. The chicks of the day gathered in the bright part 6 which is brighter than 10 lux, so that the outer edge of the bright part 6 was adjusted so as not to be darker than 10 lux. The positions of the feeding device 12 and the eating and drinking device 13 are, as shown in FIG.
Placed a little outward than the case. Floor 5 of bright part 6 in FIG.
As shown in FIG. 4, the brightness of each of the LA parts was 22 lux, the LB part was 30 lux, the LC part was 24 lux, and the LD part was 10 lux.

Thus, even a 10-day-old chick could be bred satisfactorily. As shown in Table 1, the growth status (body weight) of the chicks in this example was the same as that in the conventional breeding method (when using ticguard).

[0019]

The chicks aged 10 days were then placed in the breeding house 1
The inside of the plant was dimly adjusted to about 10 lux and bred until it was shipped for 55 to 60 days, but no trouble was found in the growth thereafter.

In the above-mentioned embodiment, the diameter of the bright portion 6 of the floor surface 5 is adjusted by adjusting the spreading condition of the umbrella body 4 covering the light bulb 3. The adjustment of the diameter of the bright portion 6 is shown in FIG. Cover the light bulb 3 with the umbrella body 15 having a predetermined spread, and adjust the height of the light bulb 3 to the ceiling 2
It is also possible that the bright portion 6 of the floor surface 5 is illuminated with a large diameter by sequentially raising it together with the umbrella body 15 from a predetermined low position via the raising and lowering means 16. Even in this case, it is desirable to adjust the brightness of the light bulb 3 with a slider or the like.

Further, in the above-mentioned embodiment, the bladder 9 is used to keep the heat, but the bladder 9 can be omitted when air conditioning heating or floor heating is performed, or in a season or area where the heat is not required.

[0023]

EFFECTS OF THE INVENTION Since the present invention takes advantage of the fact that chicks hate the dark areas and stay in the light areas, the chicks can be bred on a floor area of a predetermined diameter illuminated in a dark and wide breeding house. . Then, since the diameter of the bright part is gradually increased along with the growth of the chicks, the required space can be secured and the animals can be bred satisfactorily. In the present invention, when a large number of chicks are bred on a large scale in a large breeding house, it can be carried out by providing a predetermined number of light portions at predetermined intervals in the breeding house, and
When the number of chicks is small, it is possible to place a bright part in one large breeding house for breeding. Since the present invention utilizes the illumination by the light source, the conventional tick guard is not necessary, and the conventional problems of handling due to the tick guard are solved.
