Description

Technical Field

[0001] This invention relates to the field of ant chicken farming technology, specifically to a method for improving the growth rate of Wuzhishan ant chickens. Background Technology

[0002] "Wuzhishan Ant Chicken" originates from Wuzhishan, Hainan Province. Locals describe it as being as small as an ant, hence the name. Wuzhishan Ant Chicken is characterized by its glossy plumage, crispy bones and skin, thin skin, tender meat, and a texture similar to bird meat. It is fragrant, sweet, and has an excellent taste, making it a high-quality free-range chicken breed. This breed also possesses medicinal value, including tonifying the kidneys and blood, enhancing immunity, and promoting nutrient circulation in the body.

[0003] The Wuzhishan Ant Chicken is small in size, typically weighing around 2 jin (approximately 1 catties), and usually requires 150-200 days of raising to reach market weight. Traditionally, this breed is fed insects, wild vegetables, grains, and regular chicken feed. However, this traditional method results in slow growth, making it difficult to meet commercial demands. Using high-fat, high-protein feed to promote growth often leads to excessively rapid weight gain without corresponding improvement in body size, resulting in suboptimal development and egg production later on. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention proposes a method to improve the growth rate of Wuzhishan ant chickens.

[0005] The present invention adopts the following technical solution:

[0006] A method for improving the growth rate of Wuzhishan Ant Chicken, divided into free-range and cage-raising stages, includes the following steps:

[0007] (1) Free-range stage: Erect sheds and fences in the free-range area; feed free-range feed;

[0008] The feed formulation for free-range farming includes: 55-86 parts by weight of corn flour, 22-30 parts by weight of wheat bran, 14-25 parts by weight of soybean meal, 12-28 parts by weight of fish oil, 17-25 parts by weight of sweet potato, 12-16 parts by weight of schisandra chinensis, 10-13 parts by weight of pine needles, 9-17 parts by weight of fish meal, and 8-10 parts by weight of pumpkin powder.

[0009] (2) Cage rearing stage: Feed cage rearing feed;

[0010] The cage-rearing feed formula includes: 55-86 parts by weight of corn flour, 17-25 parts by weight of sweet potato, 22-30 parts by weight of wheat bran, 10-16 parts by weight of soapberry thorn, 14-25 parts by weight of soybean meal, 12-17 parts by weight of Litsea cubeba, 12-28 parts by weight of fish oil, 5-11 parts by weight of Acanthopanax senticosus, 10-15 parts by weight of Paeonia lactiflora, 5-9 parts by weight of Spatholobus suberectus, 7-8 parts by weight of soybean, 4-7 parts by weight of Dryopteris crassirhizoma, and 4-6 parts by weight of Polygonum hydropiper.

[0011] Cage management: Set up a blue light source and turn on the light for 2-3 hours every night.

[0012] Different feed formulas are used for free-range and cage-rearing stages. If the chicken feed is changed too early during the free-range stage, it will affect the physiological transformation of the ant chickens, which are not yet fully developed, and thus affect bone development and growth rate.

[0013] Ideally, animals should be free-range until 90 days old, and then caged from 90 days old.

[0014] Preferably, the greenhouse height is 1.7-2m and the light transmittance is 50%-70%.

[0015] Preferably, the feed is given twice a day, with the daily feed amount being 6%-8% of the chicken's body weight.

[0016] Preferably, the cage density is no more than 3 animals per square meter.

[0017] Preferably, the luminous intensity of the light source is 7000-9000 lx.

[0018] Preferably, the light source irradiation time is 2-3 hours, and the light source is turned on to irradiate from 9-10 pm.

[0019] Light can act on the hypothalamus and pineal gland of the ant-like chicken, affecting its hormone secretion and thus influencing the body. The timing and duration of light exposure determine the level of hormone secretion in the body. In this invention, the light source is turned on for 2-3 hours starting at 9-10 PM; the light exposure time should not be too long or too short.

[0020] Preferred free-range feed formulation includes: 70 parts by weight of corn flour, 30 parts by weight of wheat bran, 25 parts by weight of soybean meal, 12 parts by weight of fish oil, 17 parts by weight of sweet potato, 16 parts by weight of schisandra chinensis, 13 parts by weight of pine needles, 9 parts by weight of fish meal, and 8 parts by weight of pumpkin powder.

[0021] Preferred cage-rearing feed formulation includes: 55 parts by weight of corn flour, 22 parts by weight of sweet potato, 22 parts by weight of wheat bran, 16 parts by weight of soapberry thorns, 14 parts by weight of soybean meal, 14 parts by weight of Litsea cubeba, 12 parts by weight of fish oil, 11 parts by weight of Acanthopanax senticosus, 10 parts by weight of Paeonia lactiflora, 9 parts by weight of Spatholobus suberectus, 7 parts by weight of soybean, 4 parts by weight of Dryopteris crassirhizoma, and 4 parts by weight of Polygonum hydropiper.

[0077] Example 6: A method to improve the growth rate of Wuzhishan ant chickens

[0078] Divided into free-range stage and cage stage

[0079] (1) Free-range stage: Healthy and uniformly weighted 30-day-old Wuzhishan Ant Chickens are free-range on grasslands. Before 90 days of age, they are fed free-range feed. The free-range area needs to be equipped with a shed with a height of 2m and a light transmittance of 50%-70%.

[0081] (2) Cage rearing stage: The cage rearing density is 3 birds per square meter. Starting from 90 days of age, the birds are fed cage feed twice a day. The daily feed amount is 6%-8% of the chicken's body weight.

[0082] The cage-rearing feed formula is as follows: 55g corn flour, 22g cooked sweet potato, 22g wheat bran, 16g soapberry thorns, 14g soybean meal, 14g Litsea cubeba, 12g fish oil, 11g Acanthopanax senticosus, 10g Paeonia lactiflora, 9g Spatholobus suberectus, 7g soybean, 4g Dryopteris crassirhizoma, and 4g Polygonum hydropiper.

[0084] Other management methods will be carried out in accordance with conventional methods.

[0085] Comparison of breeding effects in various embodiments:

[0086] Thirty hens aged 120 days and 150 days were randomly selected from each group, and their weight and body size were measured. The results are shown in Table 1.

[0087]

[0088] Body length, keel length, and shank length are important indicators reflecting body development and have a significant impact on egg production performance. In flocks where keel and shank lengths increase but body weight is relatively low, egg weight is small in the early stages of laying and egg production increases slowly. In flocks where keel and shank lengths do not increase significantly but body weight increases too rapidly, premature laying and vent prolapse may occur.

[0089] Compared to Example 1, in Example 2, the amount of soapberry thorns added was replaced with fish oil; in Example 3, the amount of Litsea cubeba added was replaced with fish oil; in Example 4, the blue light source was replaced with red light; in Example 5, a feed formula without added Chinese herbal medicine was used (the amount of added Chinese herbal medicine was supplemented with other raw materials); and in Example 6, the feed from the cage-rearing stage was used directly during the free-range stage. The results of Examples 1-6 show that the ant chickens in Example 1 had the fastest growth rate and balanced weight and body size growth. The weight and body size indicators of Example 1 at 120 days of age were comparable to or significantly higher than those of other examples at 120 days and 150 days of age. These results indicate that using the segmented cultivation method of the present invention, feeding free-range feed and cage-rearing feed separately, and irradiating with blue light during specific time periods at night during the cage-rearing stage, can effectively improve growth rate and promote balanced and rapid growth in weight and body size, thereby increasing the overall commercial value of the ant chickens.

[0090] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
