Description

Technical Field

[0001] The invention relates to the technical field of breeding, and in particular to a method for feeding Chinese native pigs with chicory as a staple food and corn as a supplementary food. Background Art

[0002] Native pigs are a native pig breed in my country, formed through long-term natural selection and artificial breeding. They have a long history of breeding and have gradually adapted and evolved in a specific geographical environment.

[0003] Although the feed conversion rate of native pigs is not as good as that of hybrid breeds, the taste of native pork is tender and juicy, and the meat is firm and chewy. This is because native pigs have a long growth cycle, thicker muscle fibers, and accumulate more flavor substances during the growth process. With the improvement of living standards, more people are pursuing native pigs with better meat quality, and the price of native pigs is also higher, which has brought a better high-end market.

[0004] Traditional feeding mainly relies on feed and corn, but in order to further improve meat quality and reduce breeding costs, the applicant has developed a method for feeding Chinese native pigs with chicory as the main food and corn as the supplementary food.

[0005] Chicory has strong regeneration ability, strong stress resistance, heat resistance and cold resistance. When the temperature reaches minus 3-5℃, the leaves are still dark green, and it can survive the winter at minus 30℃. It is not demanding on soil and grows well in fertile soil with a pH of 5-8, which is suitable for planting in most parts of my country. Its leaves are tender and juicy, rich in nutrients, and high in crude protein, making it a high-quality natural feed. It also has the functions of clearing away heat and detoxification, diuresis and swelling, clearing the liver and gallbladder, and strengthening the stomach and digestion, which can promote the digestion and absorption of native pigs and enhance disease resistance. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a method for feeding Chinese native pigs with chicory as the main food and corn as the supplementary food, so as to solve the technical problems in the above-mentioned background technology.

[0007] The technical solution of the present invention is:

[0008] A method for feeding Chinese native pigs with chicory as the main food and corn as the supplementary food, comprising the following steps:

[0009] (1) The Chinese native pig breeds selected by the farms are purebred Wujin pigs, Xiangxi black pigs or Luodai black pigs;

[0010] (2) crushing the harvested chicory with a green fodder crusher for later use;

[0011] (3) Purchase corn of reliable quality, crush it into powder, and use feed pelleting equipment to mature it at a high temperature of 135-140 degrees Celsius to make pellets for use. No additives are added during the maturation process;

[0012] (4) chicory and cooked corn are mixed in the following proportions according to the weight stages of Chinese native pigs: when the pig weighs 30-40 catties, chicory is 20% and cooked corn is 80%; when the pig weighs 40-60 catties, chicory is 40% and cooked corn is 60%; when the pig weighs 60-100 catties, chicory is 60% and cooked corn is 40%; when the pig weighs 100-150 catties, chicory is 70% and cooked corn is 30%; when the pig weighs more than 150 catties until it is ready for slaughter, chicory is 85% and cooked corn is 15%;

[0013] (5) Pour the cooked corn into a blender, then add 100-degree Celsius boiling water to blend the cooked corn into a slurry. Then pour the crushed fresh chicory into the blender and add an appropriate amount of cold water to mix evenly. Cook the chicory to 30-40%. After blending, put it in a cart and pull it into the pen for feeding.

[0014] Furthermore, in step 5, the feeding temperature is 40-50 degrees Celsius.

[0015] Furthermore, it also includes temperature control, which controls the temperature of the pig house between 18-25℃. When the temperature is too high in summer, water curtains and fans are installed to cool down and ventilation is strengthened. In winter, the temperature in the pig house is maintained by increasing the thickness of the bedding and closing the doors and windows of the pig house.

[0016] Furthermore, it also includes humidity control, controlling the relative humidity of the pig house at 65%-75%. When the humidity is too high, the humidity can be reduced by increasing ventilation. When the humidity is too low, the humidity can be increased by placing a water basin or water curtain in the pig house.

[0017] Furthermore, it also includes group feeding;

[0018] a. Grouping by age and weight: raising pigs of similar age and weight together to avoid problems such as uneven feeding and mutual squeezing caused by large individual differences, and to facilitate the uniform proportion and feeding of chicory and corn cooked food;

[0019] b. During the fattening stage, boars and sows are raised separately to facilitate targeted management.

[0020] Furthermore, it also includes regular feeding, feeding twice a day, at 08:30 in the morning and 16:30 in the afternoon respectively.

[0021] The present invention is beneficial in that:

[0022] The invention adopts chicory as the staple food and corn as the supplementary food to feed the Chinese native pigs, thereby reducing the feeding amount of corn and not adopting industrial feed for feeding. The feeding cost of the native pigs is low and the meat quality can be greatly improved. The medicinal property of chicory can enhance the disease resistance of the native pigs and help the native pigs digest and absorb nutrients, thereby improving the absorption rate of feed. The corn is crushed and then cooked and granulated, and then stirred and gelatinized with boiling water, and then mixed with chopped chicory for feeding, thereby greatly reducing the preparation time of feed, and feeding is more convenient and quick. In addition, chicory has strong growth adaptability, so that the method can be applied to most areas of my country. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 It is a schematic diagram of the process of the present invention. DETAILED DESCRIPTION

[0024] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figure 1 As shown:

[0026] A method for feeding Chinese native pigs with chicory as the main food and corn as the supplementary food, comprising the following steps:

[0027] (1) The Chinese native pig breeds selected by the farms are purebred Wujin pigs, Xiangxi black pigs, Luodai black pigs, etc.;

[0028] (2) transporting the harvested chicory from the chicory planting base to a special chicory processing workshop on a breeding farm by a tricycle, and crushing it with a green fodder crusher for later use;

[0029] (3) Purchase corn of reliable quality, crush it into powder, and use feed pelleting equipment to mature it at a high temperature of 135-140 degrees Celsius to make pellets for use. No additives are added during the maturation process;

[0030] (4) chicory and cooked corn are mixed in the following proportions according to the weight stages of Chinese native pigs: when the pig weighs 30-40 catties, chicory is 20% and cooked corn is 80%; when the pig weighs 40-60 catties, chicory is 40% and cooked corn is 60%; when the pig weighs 60-100 catties, chicory is 60% and cooked corn is 40%; when the pig weighs 100-150 catties, chicory is 70% and cooked corn is 30%; when the pig weighs more than 150 catties until it is ready for slaughter, chicory is 85% and cooked corn is 15%;

[0031] (5) Operational procedures for feeding cooked food to Chinese native pigs: Chinese native pig farms are equipped with a set of 100-degree boiling water equipment and a feed mixer. First, pour the cooked corn into the mixer, then add 100-degree boiling water to stir the cooked corn into a slurry, then pour the crushed fresh chicory into the mixer and add an appropriate amount of cold water to mix evenly. The chicory should be cooked to 3-4 degrees to avoid excessive cooking and loss of chicory nutrients. After mixing, put it in a cart and pull it into the pen for feeding (the cooked feed temperature should be 40-50 degrees). It also includes regular feeding, feeding twice a day, at 08:30 in the morning and 16:30 in the afternoon.

[0032] The following points should be noted during feeding:

[0033] The first is temperature control. The suitable growth temperature for Chinese native pigs is generally between 18-25℃, which needs to be controlled in this range. In summer, when the temperature is too high, cooling measures should be taken, such as installing water curtains and fans. Water curtains can take away heat through the evaporation of water and reduce the temperature in the pig house. Fans can enhance air circulation and play a role in ventilation and cooling. In winter, attention should be paid to keeping the pig house warm. The temperature in the pig house can be maintained by increasing the thickness of the bedding, closing the doors and windows of the pig house, etc.

[0034] The second is humidity control. It is ideal to keep the relative humidity in the pig house at 65%-75%. If the humidity is too high, it is easy for bacteria and mold to grow in the pig house, causing diseases. At this time, the humidity can be reduced by increasing ventilation. If the humidity is too low, it is easy to cause the pig's respiratory mucosa to dry out and reduce the respiratory defense ability. The humidity can be increased by placing a water basin in the pig house.

[0035] There is also group feeding to facilitate feed proportioning, feeding and management.

[0036] a. Grouping by age and weight: raising pigs of similar age and weight together to avoid problems such as uneven feeding and mutual squeezing caused by large individual differences, and to facilitate the uniform proportion and feeding of chicory and corn cooked food;

[0037] b. During the fattening stage, boars and sows are raised separately to facilitate targeted management.

[0038] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
