Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention allows the movement of pigs into two groups: a breeding group and a fattening group.
This invention relates to an intensive pig farming system that divides the line into flow lines and arranges pigpens along the flow lines.

[Conventional technology]

Pork is widely consumed as a popular protein source, and pig farming is actively conducted to reflect the demand environment.

Pig farming can be broadly divided into breeding and fattening, and when breeding parent pigs are raised and piglets are born, the piglets are raised and fattened until they reach a shipping weight. Traditionally, when piglets are born and reach the weaning period, they are separated from their parent pigs and moved to another pigpen for rearing and fattening. Because they are different, careful feeding and other rearing conditions and environmental adjustments are required to increase productivity.

[Problem that the invention seeks to solve]

Pigs can be broadly divided into mother pigs, breeding pigs, fattening pigs, early pregnancy pigs, and stud pigs, and each pig has its own suitable temperature. Generally, the larger the pig, the lower the ambient temperature is desirable, and the ambient temperature has a large effect on the weight gain of the pig. For example, high temperatures increase vascular nerve movement, hormones, and respiratory rate, adding heat stress. As a result, appetite decreases and the amount of heat generated decreases. As a result, feed intake decreases and weight gain also decreases, resulting in so-called hyperthermia. In addition, when the temperature is low, not only does the body maintain its body temperature by dissipating the heat obtained from the feed, but growth and productivity are stopped and energy is used to maintain physical strength, resulting in a decrease in weight gain and loss of weight. to cause

In addition, in pigpens, manure and urine emit a strange odor, and the humidity increases, causing many sanitary problems.

However, in conventional pig farming facilities, it has been difficult to provide optimal breeding and environmental conditions that meet the above requirements.

The present invention solves the above-mentioned problems, and aims to provide a pig farming system that can raise pigs under optimal environmental conditions according to their growth process and improve productivity.

[Means for solving problems]

To this end, the pig farming system of the present invention divides the movement of pigs into two lines of movement, one for the breeding group and the other for the fattening group, centering around the farrowing pigsty, with the stall pigsty and group/boar pigsty placed adjacent to each other on one side, and on the other side. It is characterized by having a rearing pigsty and a fattening pigsty adjacent to each other, as well as rationalizing feeding facilities, optimum environment facilities, manure processing facilities, etc.

[Effect]

In the pig farming system of the present invention, the pig pens are arranged along each flow line of the breeding group and the fattening group, so each pig pen can be structured according to the pig breeding process, which saves labor in moving and managing pigs. It is possible to aim for Furthermore, since the feed and manure treatment facilities are centrally located, the structure of the pigpen can be simplified and a good environment can be maintained.

In FIG. 1, a group housing/male pigpen 5 is a pigpen for breeding, and is equipped with a ventilation fan 20 on the roof and has a double ceiling structure to adopt an open forced ventilation system. The group housing for sows is installed in a location where the sows can be reared in groups and males can be seen, as shown in Figure 2. The pig stall is
Manure is scraped off into a feces removal pit 25 from a central drainboard on a concrete flat floor.

Stall pigpen 4 is a pigpen in which pregnant sows are managed, and stall shelves are used to make it easier to manage the sows and raise a large number of pigs in a small area, and the floor structure is , raise the floor of the pig stall to a level higher than the aisle. Therefore, spilled water and urine can be easily drained, making the pig stall always sanitary.

The farrowing pigpen 3 is designed to protect small pigs with weak resistance from rapidly changing external weather conditions, prevent pathogens from entering from the outside, and enable setting of an optimal environment for the piglets.
As shown in the figure, the structure will adopt a windless negative pressure ventilation system equipped with 27 automatic air vents and 2 ventilation fans. The super farrowing pig pen 28 has an expanded metal core with an uneven floor surface and is coated with a special resin.

By doing this, it is possible to give a moderate amount of pine surge stimulation to the pig's body, increasing the heat retention effect, and the processed surface is highly elastic, which prevents scratches on the feet and knees, and prevents diseases caused by this. You can shut it out. In addition, the synergistic effect of moderate unevenness and mesoche allows it to firmly support the pigs' feet. Furthermore, compared to metal or concrete, there is no risk of slipping and getting tripped, so accidents such as sows getting their piglets trapped under them can still be reduced.

In particular, by using a mesh with a rounded and smooth finish, the excrement will fall off better, making it more sanitary and reducing the work involved in disposing of the excrement.

The breeding pigpen 2 uses a cage type floor material coated with resin (orange bat). Such a structure is effective in preventing pig accidents and reducing stress during the breeding stage. The breeding cage allows the piglets to lie down comfortably on the floor, and also allows them to get up easily and avoids the coldness of metal materials. Also,
By providing appropriate elasticity and heat retention, it relieves stress in pigs and increases efficiency in raising piglets.

The fattening pigpen 1 is divided into a sleeping area and a toilet area, with the sleeping area separated by a concrete panel and the toilet area separated by an iron fence so that excrement can be carried out in the toilet.

In addition, feeding is carried out for each pigpen from the feed store/hanger 10 through each feed tank 11, and fecal removal is carried out using the outside bit 7.
．． 8 to the excrement processing work 6. These processes can be labor-saving by timer control. Also,
For water supply, use a nipple so that you always have access to fresh water.

In general, pigs are strong against cold and weak against heat. It is well known that they are particularly sensitive to high temperatures and lose weight because they cannot breathe through their skin. Therefore, in livestock barns that are exposed to direct sunlight, the roof and walls are at high temperatures, and the radiant heat tends to keep the barns at high temperatures until nighttime, resulting in strong odors. In such cases, simply opening windows to let in fresh air through natural ventilation is insufficient. Forced ventilation is therefore necessary.

This forced ventilation causes the air around the livestock to flow, increasing the amount of evaporation and lowering body temperature by releasing latent heat, which is extremely effective as a countermeasure against high temperatures. In other words, in order to increase pig productivity, it is necessary to control the environment in the pigpen to match natural conditions.

Each pigpen in the pig farming system of the present invention has a double ceiling as a whole, and air is constantly allowed to flow between the two to prevent temperature rise in the house due to roof heating, that is, radiant heat. FIG. 4 shows an example of this. In this example, a ventilation fan 32 is installed on the roof, and a fan controller 33 for controlling the operation of the ventilation fan 32 and a temperature sensor 1-34 are installed inside the building. The ventilation fan 32 is operated to constantly monitor the temperature of the pig and keep it at the optimum temperature for the pig.

The environment inside a pigsty is affected not only by changes in the outside air, but also by the heat generated by the pigs and the loss of moisture.Ventilation adjusts environmental factors such as temperature, humidity, odor, floating bacteria, and fine dust inside the pigsty. This is the most effective means of doing so. Therefore, appropriate environmental balance can be maintained in terms of temperature and humidity within the pigpen by appropriate ventilation control. For example, temperature equilibrium is related to sensible heat generation, heat loss from the building, and ventilation rate.

The pig farming system according to the present invention is an open type pigsty and has a structure in which no cooling device is installed, so that the rise in temperature in the pigsty is reduced as much as possible, and the temperature is lowered by constant ventilation, so that the sensible temperature is as cool as possible.

As described above, the pig farming system according to the present invention has a farrowing pigpen 3.
The movement of pigs can be divided into two lines of movement: breeding groups and fattening groups. FIG. 5(a) shows the movement cycle of pigs in the breeding group, and FIG. 5(b) shows the movement of pigs in the fattening group. According to this flow line, approximately 1/2 of each pigsty facility
Secure a route for the manager and a flow line for breeding and fattening groups in the center of 2.

Next, an example of management of each pigpen will be explained.

In the group housing/male pigpen 5, the pig stall into which the mother pig is introduced is thoroughly cleaned and disinfected at least the day before, and the floor surface is dried. Pigs have a habit of using damp places as latrines,
Immediately before introducing the dog, spray water on the area where you want it to poop to moisten it so it remembers the toilet.

Mother pig pens that are determined to be pregnant are transferred to stall pig pen 4, which is easy to manage and has a structure that allows for raising a large number of pigs in a small area, and care is taken not to let the bellies get cold, and to prevent and detect diseases such as colds. , consider treatment. Then, the feed amount is adjusted according to the season.

One week before the scheduled farrowing date, the sow is moved to farrowing pigpen 3, but before that, the sow's body is thoroughly cleaned and disinfected using a washer. Newborn pigs are extremely sensitive to temperature, so their environment must be adjusted to maintain the appropriate temperature. After the piglet reaches 21 days of age, it grows to about 4 to 5 times its original weight, so at this time the mother pig is moved, raised here for several days, weaned, and moved to the breeding pigpen 2.

Moved to breeding pigpen 2, over 80 days old and weighing 40~
When the pigs reach around 50 kg, they are moved to fattening pigpen 1. The pigs moved to the fattening pigpen 1 reach their shipping weight around 180 days of age.

As described above, the pig farming system according to the present invention has a farrowing pigpen 3.
The movement of pigs is divided into two lines of movement, one for the breeding group and one for the fattening group, and each pigpen is placed adjacent to the other along this line of movement, along with a feces fermentation processing facility 6, a native heat treatment facility 9, and a feed store/hanger. 10 etc., feed and water supply facilities, and excrement processing facilities will be centrally located. Therefore, even when the pigs enter each facility, the movement of the pigs only takes half the length of the total length of the pigpen, and it is possible to save labor in moving the pigs, which requires the most labor. In addition, the bulk disinfection that must be performed when moving pigs to each facility can be provided in the central management passageway of each facility, so that cleaning and disinfection must be performed before entering the pigpen. In addition, in order to easily adjust the pigpen environment, all pigpens except farrowing pigpen 3 adopt an open forced ventilation system. Windless negative pressure ventilation method 2 will be adopted due to the need for high humidity.

C Effects of the Invention] As is clear from the above explanation, according to the present invention, pigsty corresponding to the breeding environment is arranged in two lines for the breeding group and the fattening group, so the pigsty can be arranged according to the breeding process. Simplification of the structure, which can be made into a suitable structure
In addition to reducing construction costs, pigs can be raised in an optimal environment and productivity can be increased. Furthermore, since the waste and excrement treatment is separated from the pigsty and processed outside the pigsty, the problem of unpleasant odors inside the pigsty can be solved, and the environment inside the pigsty can be maintained in a good condition.
