What are the benefits of sand mating in the chicken coop and the benefits of padding sand in broiler

Commonly used bedding raw materials are shavings, wheat straw, straw, sawdust, sand, all kinds of bedding raw materials have different advantages and disadvantages, the best is to choose different bedding mixed use.

Shavings have good moisture absorption and degradability. However, it is susceptible to pesticide contamination, resulting in broiler poisoning. At the same time, chloramines are easy to form, causing the litter to deteriorate quickly. In fact, due to the fact that shavings** are more expensive and scarce, they are rarely used.

Wheat straw and straw, generally used after cutting, are soft and hygroscopic. However, it is susceptible to contamination by pesticides, molds and their toxins, which is harmful to the health of broilers. The degradation rate is slower than that of shavings, and it is easy to ferment and produce heat, so it is not suitable for use alone. It is best mixed with 50% shavings.

Rice husks, loose and easy to use. However, it is slightly less hygroscopic and susceptible to pesticide contamination, so it is best to mix it with other litter. Rice husks are easily digested and absorbed by chickens.

Because the rice husk is easy to spread, easy to turn after use, and easy to remove and clean after slaughter, it is currently commonly used.

Sawdust is not easy to use alone, has high dust, and can be digested and absorbed.

Sand, usually used on cement floors in arid or desert areas. The effect is good, but the thickness is higher due to the fact that new sand must be added frequently, and the movement of the chickens is difficult.

Chicken farmers often put sand in the chicken coop, and there are many benefits to doing so!

Advantage 1, can increase production.

The egg production of sand in the house was higher than that without sand in the house. Caged laying hens can increase the egg production rate, increase the egg production, and improve the feed utilization rate after feeding the sand grains with a diameter of millimeters.

Benefit 2: Aid digestion.

Chickens like to eat sand, and after the sand is laid in the house, the chickens can eat the sand they need at any time, which can promote the digestion of food by the stomach and improve the utilization rate of feed.

Advantage 3: It can absorb moisture.

Sand has the effect of absorbing water, so the coop can keep the house dry and prevent moisture after sand is matted. The optimum relative humidity for laying hens is 50-55%. When the humidity is lower than 45%, the dust in the house is flying, and the chickens are prone to respiratory diseases; When the humidity is higher than 72%, it is easy to make the feathers dirty and sticky, leading to some diseases.

Benefit 4: Epidemic prevention disease.

Paving the chicken coop and activity field with sand grains can keep the chicken coop and activity field dry, keep the air fresh, and after the sand is exposed to the sun, it can make many pathogenic bacteria lose their pathogenic vitality, thereby reducing the occurrence of diseases. After the sand bath of chickens, it can also kill ectoparasites, so that nutrition can be fully used for health and production.

Extended information: Three precautions for sand mating in the chicken coop:

1. The sand used for paving the chicken coop should be clean and hygienic and replaced in time. Moist sand with chicken manure should be cleared out in a timely manner, exposed to the sun, and removed chicken manure and other dirt after drying, before it can be reused.

2. The thickness of the sand should be 3 5 cm.

3. Conditionally you can build a bath in a corner of the chicken coop or activity venue, the size of the pool can be determined by the number of chickens, and the sand of the sand bath is better to choose fine-grained sand.

Many chicken farms will spread a layer of sand in the broiler cage, as if they had laid a thick layer of "mattresses" in the broiler cage. Especially in some chicken farms in the south or during the rainy season in the north, many breeders will provide sand for the chicken coop. So what are the benefits of putting sand on top of a broiler cage?

Second, it can cool down. In summer, the weather is hot, and chickens have no sweat glands. They like to lie on the sand and play in the sand. Through the contact between the sand and the **, it can achieve the effects of heat dissipation, cooling and heat prevention.

3. The sand absorbs water, and various germs are easy to multiply in a humid environment, affecting the growth and health of chickens and reducing egg production. The sand can absorb water, keep the broiler cage chicken house environment dry and hygienic, and is conducive to the health of the chickens.

Fourth, it can help digestion. Chickens have no teeth and rely on eating some grains of sand to help grind food; Therefore, the lack of sand can lead to indigestion, so broiler cages, chicken houses and sports fields must be filled with sand.

In short, sand is very good for broiler cage chickens, not only chicken farms can provide chicken cage miles of sand on a large scale, but we can also take such measures when raising chickens at home, which is conducive to the healthy growth of chickens.

Under natural light, the chickens that hatch in the spring gradually shorten the sunshine time and egg production gradually decrease in autumn and winter. In the Beijing area, which is located at 40° north latitude, the time from sunrise to sunrise is as long as 15 hours a day at the summer solstice, and shortens to only 11 and a half hours a day at the time of cold dew. Although egg production is so low in autumn and winter, the main reasons are:

With the shortening of the sunshine time in the season, the effect of light on the chicken body decreases, and the secretion of gonadotropins in the anterior pituitary gland of chickens decreases, resulting in a decrease in egg production. This is not due to a drop in temperature, nor is it due to a decrease in the amount of sunlight and therefore a lack of nutrients for the chickens to feed intake. The appropriate lighting system is one of the important technical measures to detect the timely production of chickens and improve the egg production, which must be used properly and strictly implemented.

Laying flocks raised in closed chicken houses, rearing period: 1-3 days old 23 hours of light, 4-2 weeks old 16 hours of light, 3-18 weeks old 9 or 8 hours; The illumination is 20 lux at 1-2 weeks of age and 5-10 lux at 3-13 weeks of age. 10 hours of light per day from 19 weeks of age, then half an hour per week to 16 hours at 31 weeks of age, and then on.

The illuminance is about 20 lux, the light meter, every 3 meters set up a 40-60 watt bulb, 2-3 watts can not change the light time at will, the principle of light is that the breeding period can only reduce and can not increase the light time, the laying period can only gradually increase can not reduce the light time. It is most convenient to manage the lighting time with a time switch. For flocks kept in open coops, follow the local conditions:

Different light methods are adopted for latitude and brooding season, for example, the rearing period in northern China is: (1) 23 hours of light for the first 3 days of brooding, and 16 hours of light for 4 days to 2 weeks of age. (2) Chicks hatched between April 1 and September 15 are recalcitrant from 3 weeks old to 20 weeks old.

3) Chicks hatched between September 16 and March 31 should be supplemented with light from the age of 3 weeks at the age of 3 weeks to the longest light day at the age of 3-20 weeks during the rearing period, and according to the natural light after the longest light day. Laying period: (1):

If there is less than 12 hours of natural light at 2 weeks of age, the light should be supplemented to 12 hours at 2 weeks of age, and then increased by half an hour per week until 16 hours. (2) If natural light reaches or exceeds 12 hours at 20 weeks of age, add 15 minutes per week until 17 hours. (3) Illumination, set up a 40-watt bulb every 3 meters, and hang it above the passage between the cages.

2-3 watts per square meter. When supplementing the light, the power supply should be stable, the bulb should have a lampshade to gather light, and all parts of the house should be evenly irradiated by the light when leveling, and the trough and drinker should be placed under the bulb. When turning off the lights at night every day, you should leave a small bulb unturned off, or use a voltage regulating transformer to reduce the voltage to dim the light, and then turn off all the lights on time after the chickens are perched.

In order to prevent the flock from being frightened, or to prevent the chest from coming into contact with the hard ground that can cause a disease such as a chest cyst, the house must be covered with soft bedding. The bedding should be dry, loose, absorbent, and suitable for fertilizer. Commonly used are straw, wheat straw, wild hay, rice husks, sawdust, sawdust, shavings, leaves and plant vines.

Mouldy bedding should never be used to avoid inducing aspergillosis.

Laying method: first shovel the dirt on the upper layer of the ground, and spread a very thin layer of quicklime and dry furnace ash; Cover with a layer of dry sand with a thickness of 8 to 10 cm; The third layer is 10 15 cm thick bedding, which should not be cut too much. With the increase of age, the degree of pollution of the mat grass is gradually increased, and it is not necessary to replace it completely.

Usually, it is necessary to turn and rake loosely so that the feces fall into the bottom layer and keep the surface soft and dry. In the case of imperfect ventilation in the house, depending on the pollution of the bedding, dig and change frequently, and dry it for later use. After 20 days of age, gradually move to soft sand for rearing, and remove feces with a broom and a fine-toothed rake every day.
