Build a "three-dimensional mesh bed" brooding greenhouse to carry out professional scale brooding, and farmers can raise adult chickens with a high survival rate, low risk and easy success (those who can raise broods can start from brooding). The main points to pay attention to in brooding:

1. Room temperature: 35~32 °C at 0~1 week old, 31~24 °C at 2~3 weeks old, 23~20 °C at 4 weeks old, and 0.5 °C per day after 1 week of age.

2. Relative humidity: the relative humidity of the room is kept at 55%~65%, that is, 60%~65% before 10 days, and 55%~60% after 10 days; Keep the air fresh indoors, without pungent and smoky eyes.

3. Supplemental light: 23 hours of light per day for the first 5 days, and 17 hours of light (including natural light) thereafter.

4. Drink water and eat at the right time. Chicks should start eating and drinking as soon as possible, and do not feed and water continuously, and eat ad libitum. Add 5% glucose to the initial drinking water for two days; On the third day, 0.02%~0.03% potassium permanganate was added to the drinking water.

5. High-density brooding. Before 15 days, it was 60~70 chickens/square meter, and each batch of brooding was generally 5000 (depending on the demand of farmers for chicks to determine the brooding scale).

The combination of "net, bed, and scatter".

Farmers should appropriately renovate the chicken coop according to the number of their own breeding, requiring the indoor ground to be cement floor, with windows and floor windows, so that the air circulation and lighting are sufficient, and do a good job of net beds or chicken coops, and three-dimensional three-layer is appropriate. The number of net beds is determined by the number of chickens, which is generally calculated according to 45~20 / square meter (the density is a little higher in the early stage).

The first layer of the mesh bed is 40 cm high from the ground, the mesh bed is 30 cm high, and the distance between the upper and lower layers is 20 cm. The skeleton of the mesh bed is made of wood or white oleander, and the perimeter and bottom of the mesh bed are fixed with a plastic mesh of 1 cm × 1 cm mesh. The drum and drinker are placed in a mesh bed. The courtyard woodland is enclosed with nylon net, a pile is driven every 2~3 meters away, the nylon net is tied to the pile, and the net edge of the ground is compacted with soil. The area of the enclosed site is generally not less than 1.5 square meters per chicken, and the wider the better.

Purchased dewarmed chicks (chicks that have been brooded) are raised in a net bed at the stage of 1 kg body weight, and stocked in the enclosed yard woodland after 1 kg until the slaughter period (not put in rainy and frosty days). In feeding, the feed and water are continuous, and the food is taken freely. Raised in the net bed, the chicken's range of activity is small, the energy consumption of the chicken body is less, and the weight gain is accelerated; Chickens are free-range in the enclosed yard woodland, which can prey on wild weeds and biological insects, change the food structure, and have a high taste of meat quality (maintain the taste of native chicken meat).

Rations matched

Choose the full price pellets of broilers with comprehensive nutrition, good palatability and easy to consume, and then appropriately match other feeds to raise chickens, so as to ensure the normal growth and development of chickens, accelerate the weight gain rate and keep the chicken flavor unchanged, so it is necessary to scientifically match the diet.

During the brooding period, the full price pellets of broilers should be selected, and the feed should be slightly soaked and transformed at the beginning of eating, and a little crushed by hand. During the period of dewarming chicken to 1 kg body weight, medium chicken feed should be selected, and it should be replaced gradually, not all at once, so as not to cause stress reaction. At the same time, 5%~10% whole grains (or wheat) should be added, and 10%~15% green feed should be given.

During the free-range period in the courtyard, the full price pellet of the chicken is selected, and 10%~15% of the whole grain (or wheat) is added to the diet, and 15%~20% of the green feed is added. If you only feed the full price feed, the cost of feeding is high, and the benefits are not calculated; secondly, the chicken has a lot of intermuscular fat, which is not refreshing to eat; The third is the unique flavor of soilless chicken, which consumers don't like. Adding an appropriate amount of green feed can increase the content of vitamins, reduce the cost of breeding, and reduce the intermuscular fat content of chicken.

Disinfect immunization

Doing a good job in chicken immunization, disinfection and epidemic prevention to prevent the occurrence and spread of infectious diseases is the key to the success of large-scale chicken raising. Therefore, it is necessary to do a good job in immunization, disinfection and epidemic prevention, reduce the death of chickens, and increase the survival rate and commodity rate.

The immunization program of local chickens should be combined with the nature of production (commercial broilers), and it is best to refer to the immunization program of broilers, that is, 1-day-old chicks are immunized with Marek's vaccine (unconditionally can also be omitted, which is mainly done in hatcheries); 6~7-day-old chickens were immunized with mixed drinking water such as Newcastle disease IV seedlings (or V.4 seedlings), bursa B87 seedlings, and H120 seedlings; At the age of 24~28 days, the chicken Newcastle disease II seedlings were immunized with drinking water once; At the age of 60 days, it was inoculated once with Newcastle disease I vaccine injection, and no more immunization was given in the future.

Adding some drugs to feed drinking water can prevent the occurrence of diseases. At the age of 2~7 days, add 0.02% dysentery and 0.01% oxytetracycline or penicillin, gentamicin, etc., and repeat the above drugs at the age of 13~17 days. At the age of 19~90 days, add chlorobenzene, anti-ball king and other anticoccidial drugs to the feed for deworming, and the chicken house should be cleaned every day, and the ground and manure bearing board should be disinfected with quicklime. Spray and disinfect the outside of the house with compound phenol mixed with water every half month, and disinfect the chickens in the chicken coop with 100 poisons. After slaughtering, the site should be thoroughly cleaned, washed and disinfected; The disinfection pool at the door of the chicken coop should always have lime or disinfectant, and pay attention to changing it frequently.

A reference for the design of the pig barn

Pigs have evolved to be quite adaptable to the environment, but in intensive pig farms, pigs will be significantly less adaptable, so it is necessary to create good environmental conditions for them. The planning of pig houses is not only related to the efficiency of pig farm management, but also inseparable from the control of pig diseases and pollution prevention. The following introduces the design methods of pig barns in Taiwan for the reference of colleagues.

1 boar barn

When designing the boar house, it should be considered that it can maintain the health of the boar's feet and meet the requirements of the boar's ** for ambient temperature, so as to ensure that it has normal breeding ability and good ** quality.

1.1 Maintain the normal reproductive performance of boars

The goal of raising boars in pig farms is to breed good mating performance and breeding body condition, and normal mating and reproduction. Therefore, it is necessary to avoid facilities in the boar pen that harm the reproductive performance of the boar. For example, it should not be allowed to climb up and develop the paralysis of masturbation, otherwise it will hurt the genitals of the male animal, and the phenomenon of immature sperm often appears; For example, the boar pen is too narrow, which will lead to friction and trauma, which will affect reproductive performance.

1.2 Avoid high temperature environment on the boar will seriously affect the reproductive performance of the boar, so the boar house must take into account the heatstroke prevention and cooling facilities. For example, the roof is insulated, sprinkled with water or a shower bath, ventilation facilities and even air-conditioning equipment are installed in the club, and the fence behind the boar pen is fenced off by a railing to facilitate ventilation.

1.3 Prevent the design of the pig pen from injuring the hooves and feet

When breeding boars, whether they are naturally bred or artificially harvested, the most important part to support their weight is the hind feet. In order to prevent damage to the boar's feet and hooves, the following points should be noted:

a) All floor coverings should be considered for those that remain non-slippery after washing or urinating.

b) The ground should not be too rough to avoid abrasion to the trotters.

c) Avoid using strip floors in boar pens, and use cement floors that are not too slippery or too rough and high-pressure cement brick floors (strong and non-slip) are advisable; If there are boars with poor footsteps, some sandy ground can be mined, which will be conducive to the health of the pig's feet.

d) The bar should not be too low, so as not to climb up and down the boar, and the height of the bar should be 130cm.

1.4 The boar pen should be designed with the sow pen to be mated

The fact that the sow can see or smell the boar every day, or that the head touches each other can help to stimulate the sow's anger. Generally, the boar pen is set opposite the sow pen, next to the sow pen to be in estrus or several boar pens are set in the middle of the sow pen.

1.5 Easy to manage

a) Set up a semen collection room in the boar barn, and set up a laboratory next to it to test the quality of the best.

b) The public body is strong, and the equipment should be strong c) The boar pen should not accumulate water in the sand and rain in rainy days, otherwise it is easy to have mosquitoes and cause the boar to be restless.

d) The drainage is good, and the ground slope should be 1/30.

1.6 Plenty of room to exercise

Boars should have moderate exercise every day to enhance boar physique, improve quality, and maintain their normal reproductive performance. Generally, the sports field is a sandy ground or concrete floor, built outside the house next to the fence, and the size is equivalent to the size of the fence.

2 Sows to be mated (gestation house)

The definition of sow refers to the period from weaning to the next reproduction, the period of time when the sow does not produce milk is called the dry milk period, which includes the waiting period from weaning to remating and the gestation period from mating to production, during which the design of the pig house should pay attention to the following six principles.

2.1 Make weaned sows come into heat as soon as possible

There are many ways to promote weaned sows to come into heat as soon as possible, including merging, driving pigs, boar stimulation, hormone therapy, chasing sows that have not been in heat for a long time with boars and raising sows in a group and other methods, among which the pen and sows can be fed in the pig pen design to achieve the effect, and the general group breeding is better than 3~4 heads per group. It is also possible to place the boar pen near the sow pen or drive the boar to the sow pen every day to stimulate the sow to come into heat.

2.2 It is easy to control the amount of food that the sow eats

The fat and thinness of the sow can be controlled by the amount of food to avoid too much or too little feed intake due to competition. Over-fattening can easily cause ovarian fat infiltration, affecting egg maturation and normal estrus; Too thin, endocrine disorders, follicles do not develop properly, delayed or no estrus. Generally, it is advisable to reach 80% fat.

2.3 Prevent embryonic or fetal death after mating

a) The high temperature environment can lead to a decrease in the sow's appetite, as well as the death of non-implanted embryos within 21 days of mating and the death of the fetus between 80 days of mating and farrowing.

b) The height of the pen is appropriate to avoid the possibility of the sow turning out of the pen or next door and causing a fight and abortion.

C) The device is equipped with an automatic synchronous feeding system, which is quiet for the sow during feeding, has a high safety for the feet and fetus, and gives appropriate treatment to those who are too fat and too thin.
