Abstract
Description
Technical Field
[0001] This invention relates to the field of chicken farming, and in particular to a method for fattening Wuzhishan Ant Chicken. Background Technology
[0002] Wuzhishan Ant Chicken (hereinafter referred to as Ant Chicken) is a small breed of chicken raised in the wild by the local ethnic minorities (Li and Miao) in Wuzhishan City, Hainan Province. Because of its ant-like size, it is aptly named "Ant Chicken" by the locals. It has not been hybridized with other breeds, resulting in relatively consistent physical characteristics and stable genetic inheritance of its main economic traits. Ant Chicken meat is firm and fragrant, with thin yet chewy skin that is crisp and refreshing, and it is also highly nutritious. Ant Chicken farming has expanded from Wuzhishan City to other cities and counties such as Lingshui, Baoting, and Sanya.
[0003] Ant-feather chickens are small in size, and their meat is dry and lacks fat after slaughter, resulting in a tough texture and a lack of tenderness and juiciness. Furthermore, they are quite aggressive, and during the breeding process, they are prone to pecking and fighting, further diminishing the quality of their meat. Summary of the Invention
[0004] Therefore, the purpose of this invention is to propose a fattening method for Wuzhishan ant chickens to solve the above-mentioned problems.
[0005] The technical solution of this invention is implemented as follows:
[0006] A fattening method for Wuzhishan Ant Chicken includes the following steps:
[0007] An activity area was set up in the orchard, and a straw shed was built above the activity area. The chicken coop was connected to the activity area. Fluorescent LED lights were added to the chicken coop in sequence, and fluorescent LED lights and blue LED lights were added to both the chicken coop and the straw shed at the same time to obtain the target Wuzhishan Ant Chicken.
[0008] The fluorescent LED lamp uses phosphors prepared from magnesium carbonate, strontium carbonate, yttrium oxide, silicon oxide, and aluminum oxide.
[0009] To further explain, the preparation method of the phosphor includes: mixing magnesium carbonate, strontium carbonate, yttrium oxide, silicon oxide and aluminum oxide, grinding, adding boric acid and calcium fluoride, ball milling, calcining under an inert gas atmosphere, sieving, and obtaining phosphor.
[0010] Furthermore, the molar ratio of magnesium carbonate, strontium carbonate, yttrium oxide, silicon oxide, and aluminum oxide is 0.4–0.5:0.2–0.3:1–1.2:0.5–0.6:0.3–0.4, and the amount of boric acid and calcium fluoride added is 1–1.5 wt% of the total mass of the phosphor.
[0011] To further clarify, the calcination temperature is 800–900°C, and the calcination time is 6–8 hours.
[0012] To further explain, when adding fluorescent LED lights to the chicken coop for breeding, the chicken coop is closed, the chickens are not allowed to roam freely, the illumination time of the fluorescent LED lights is 10-12 hours / day, and the feeding under fluorescent light lasts for 30-35 days.
[0013] To further explain, when both fluorescent LED lights and blue LED lights are added to the chicken coop and straw shed for breeding, the chicken coop is opened for free-range grazing, and the ratio of fluorescent to blue light is 2-3:1-2.
[0014] To further explain, the illumination time of fluorescent LED lamps is 10-12 hours / day, and the rearing period is 40-55 days under fluorescent light. The illumination time of blue LED lamps is 6-12 hours / day, and the rearing period is 60-85 days under blue light.
[0015] To further explain, the blue LED lamp includes two stages of blue LED lamp illumination and rearing: 40-55 days and 20-30 days. The 40-55 day blue LED lamp illumination and rearing involves using blue LED lamps for 6-8 hours / day for 40-55 days. The 20-30 day blue LED lamp illumination and rearing involves using blue LED lamps for 10-12 hours / day for 20-30 days.
[0016] To further clarify, the fruit tree in question is either a pomegranate tree or a jujube tree.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0018] This invention involves constructing a free-range activity area in an orchard and sequentially adding fluorescent LED lights to the chicken coop, as well as fluorescent LED lights and blue LED lights to the straw sheds in both the chicken coop and the free-range area. This method helps to reduce the metabolic level of the ant chickens and promotes rapid fat deposition. After 100 days of raising, the crude fat content of the ant chickens reaches more than 10%, thus achieving the goal of rapidly fattening ant chickens.
[0019] The breeding method of this invention is simple. It uses a combination of fluorescent LED lights and blue LED lights to create a comfortable light environment, promote the growth and development of ant chickens, and at the same time, can quickly bring ant chickens to the level of high-quality chickens with good slaughter performance.
[0020] This invention reduces pecking and fighting among ant chickens during their breeding process. After 100 days of breeding, the crude fat content of the ant chickens reaches more than 10%, and after 130 days of breeding, the slaughter weight and slaughter rate of the ant chickens meet the requirements, resulting in ant chickens with good taste. Detailed Implementation
[0021] To better understand the technical content of this invention, specific embodiments are provided below to further illustrate the invention.
[0022] Unless otherwise specified, the experimental methods used in the embodiments of this invention are all conventional methods.
[0023] Unless otherwise specified, all materials and reagents used in the embodiments of this invention are commercially available.
[0024] The breeding base of this invention was selected in Hongya Village, Tongshi Town, Wuzhishan City, Hainan Province. Each embodiment set up 50 chicks (all of which were hens) for the experiment.
[0025] Example 1 - A fattening method for Wuzhishan ant chickens
[0026] The chicken coop was built near the pomegranate orchard, and an activity area about three times the size of the chicken coop was enclosed within the orchard. A straw shed was built above the activity area, allowing only a few rays of sunlight to pass through. The newly hatched ant chicks, averaging 5 days old, were first raised in the chicken coop and were not allowed to roam freely. The temperature in the chicken coop was 22-25℃, with good ventilation. Fluorescent LED lights were added to the chicken coop for 30 days, with the fluorescent LED lights providing 12 hours of light per day.
[0027] After feeding the chickens with fluorescent LED lights for 30 days, the chicken coop was opened to allow the ant chickens to roam freely. At the same time, fluorescent LED lights and blue LED lights were added to the straw shed, with a ratio of 3:2 between fluorescent LED lights and blue LED lights. The fluorescent LED lights in the chicken coop were then removed. When the ant chickens were released to the activity area, both fluorescent LED lights and blue LED lights were turned on. The illumination time for the fluorescent LED lights was 12 hours / day, and the illumination time for the blue LED lights was 8 hours / day.
[0028] After feeding the chickens for 40 days with a mixture of fluorescent and blue light, the fluorescent LED lights were removed, and the chickens were fed with blue LED lights for another 30 days. The blue LED lights were used for 12 hours per day until the target Wuzhishan Ant Chicken was harvested.
[0029] The preparation method of the phosphor for the above-mentioned fluorescent LED lamp is as follows: magnesium carbonate, strontium carbonate, yttrium oxide, silicon oxide and aluminum oxide are mixed in a molar ratio of 0.4:0.2:1:0.5:0.3, and after thorough grinding, 1.5 wt% of boric acid and calcium fluoride (mass ratio of boric acid and calcium fluoride is 2:1) of the total system are added. After thorough grinding, the mixture is ball-milled at 6000 rpm for 8 hours. The uniformly ground material is placed in a corundum crucible and placed in a tube furnace. Under a nitrogen atmosphere, it is calcined at 850℃ for 7 hours, cooled, and sieved to obtain the phosphor.
[0030] Example 2 - A fattening method for Wuzhishan ant chickens
[0031] The chicken coop was built near the pomegranate orchard, and an activity area about three times the size of the chicken coop was enclosed within the orchard. A straw shed was built above the activity area, allowing only a few rays of sunlight to pass through. The newly hatched ant chicks, averaging 5 days old, were placed in the chicken coop for rearing and were not allowed to roam freely. The temperature in the chicken coop was 22-25℃, with good ventilation. Fluorescent LED lights were added to the chicken coop for rearing for 35 days, with the fluorescent LED lights providing 10 hours of light per day.
[0032] After feeding the chickens with fluorescent LED lights for 30 days, the chicken coop was opened to allow the ant chickens to roam freely. At the same time, fluorescent LED lights and blue LED lights were added to the straw shed, with a ratio of 2:2 between fluorescent LED lights and blue LED lights. The fluorescent LED lights in the chicken coop were then removed. When the ant chickens were released to the activity area, both fluorescent LED lights and blue LED lights were turned on. The illumination time for the fluorescent LED lights was 10 hours / day, and the illumination time for the blue LED lights was 6 hours / day.
[0033] After feeding with a mixture of fluorescent and blue light for 40 days, the fluorescent LED lights were removed, and the blue LED lights were used to continue feeding for 25 days. The blue LED light duration was 10 hours / day until the target Wuzhishan Ant Chicken was harvested.
[0034] The preparation method of the phosphor for the above-mentioned fluorescent LED lamp is as follows: magnesium carbonate, strontium carbonate, yttrium oxide, silicon oxide and aluminum oxide are mixed in a molar ratio of 0.4:0.2:1:0.5:0.3, and after thorough grinding, 1.5 wt% of boric acid and calcium fluoride (mass ratio of boric acid and calcium fluoride is 2:1) of the total system are added. After thorough grinding, the mixture is ball-milled at 6000 rpm for 8 hours. The uniformly ground material is placed in a corundum crucible and placed in a tube furnace. Under a nitrogen atmosphere, it is calcined at 850℃ for 7 hours, cooled, and sieved to obtain the phosphor.
[0035] Comparative Example 1 - A fattening method for Wuzhishan ant chickens
[0036] The chicken coop was built near the pomegranate orchard, and an activity area about three times the size of the chicken coop was enclosed within the orchard. A straw shed was built above the activity area, allowing only intermittent sunlight to pass through. The newly hatched ant chicks, averaging 5 days old, were first raised in the chicken coop and were not allowed to roam freely. The temperature in the chicken coop was 22-25℃, with good ventilation. White LED lights were added to the chicken coop for 35 days, with the white LED lights illuminating the chickens for 10 hours per day.
[0037] After feeding the chickens with white LED lights for 30 days, the chicken coop was opened to allow the ant chickens to roam freely. At the same time, white LED lights were added to the straw shed, and the fluorescent LED lights in the chicken coop were removed. The white LED lights in the straw shed were used for 10 hours / day until the target Wuzhishan ant chickens were harvested.
[0038] Experiment 1
[0039] The thickness of the skin at the corners of the cut skin along the midline of the back, obtained from the Wuzhishan Ant Chicken, was measured using vernier calipers and recorded as subcutaneous fat thickness. The crude fat content of the leg muscles was determined according to the "Determination of Fat in Food" (GB 5009.6-2016). The results are shown in Table 1 below.
[0040] Table 1. Subcutaneous fat thickness and crude fat content of Wuzhishan Ant Chicken
[0041] project Subcutaneous fat thickness / mm Crude fat content / % Example 1 8.78±0.42 10.33±0.96 Example 2 8.26±0.56 10.01±0.84 Comparative Example 1 6.35±0.81 7.72±1.02
[0042] As shown in Table 1 above, the subcutaneous fat thickness of the ant chickens in Examples 1 and 2 was higher than that in Comparative Example 1, and the crude fat content was also higher. By sequentially adding fluorescent LED lights in the chicken coop, and then simultaneously adding fluorescent LED lights and blue LED lights in the chicken coop and hay shed, it is helpful to reduce the metabolic level of the ant chickens and promote rapid fat deposition. Fluorescent powder prepared from magnesium carbonate, strontium carbonate, yttrium oxide, silicon oxide, and aluminum oxide was used to feed the ant chickens. This, together with the blue LED lights, created a comfortable light environment, avoiding the visual impairment caused by the cold white fluorescent lights under blue light and reducing the ant chickens' sensitivity to light sources. At the same time, the combination of the two light sources during the free-range stage helps to reduce the ant chickens' aggressive and ambitious emotions, allowing them to move independently in the orchard activity area without external interference, which can further promote their growth and development. Blue light also helps to soothe and regulate the mood of the ant chickens. In subsequent feeding, the fluorescent LED lights can be turned off, and only blue LED lights can be used for feeding to improve the fattening effect.
[0043] Example 3 - A fattening method for Wuzhishan ant chickens
[0044] The chicken coop was built near the pomegranate orchard, and an activity area about three times the size of the chicken coop was enclosed within the orchard. A straw shed was built above the activity area, allowing only a few rays of sunlight to pass through. The newly hatched ant chicks, averaging 5 days old, were first raised in the chicken coop and were not allowed to roam freely. The temperature in the chicken coop was 22-25℃, with good ventilation. Fluorescent LED lights were added to the chicken coop for 30 days, with the fluorescent LED lights providing 12 hours of light per day.
[0045] After feeding the chickens with fluorescent LED lights in the chicken house for 30 days, the chicken house was opened to allow the ant chickens to roam freely. Fluorescent LED lights were added to the straw shed, and the fluorescent LED lights in the chicken house were removed. When the ant chickens were released into the activity area, the fluorescent LED lights were turned on. The illumination time of the fluorescent LED lights was 12 hours / day until the target Wuzhishan ant chickens were harvested.
[0046] The preparation method of the phosphor for the above-mentioned fluorescent LED lamp is as follows: magnesium carbonate, strontium carbonate, yttrium oxide, silicon oxide and aluminum oxide are mixed in a molar ratio of 0.4:0.2:1:0.5:0.3, and after thorough grinding, 1.5 wt% of boric acid and calcium fluoride (mass ratio of boric acid and calcium fluoride is 2:1) of the total system are added. After thorough grinding, the mixture is ball-milled at 6000 rpm for 8 hours. The uniformly ground material is placed in a corundum crucible and placed in a tube furnace. Under a nitrogen atmosphere, it is calcined at 850℃ for 7 hours, cooled, and sieved to obtain the phosphor.
[0047] The pecking and fighting among the ant chickens in Example 3 during the breeding process was more severe compared to Example 1.
[0048] Experiment 2
[0049] After removing the blue light in the above embodiments, the animals were raised for another 30 days. The slaughter performance was then measured in accordance with the relevant provisions of the "Operation Manual for the Third National Survey of Livestock and Poultry Genetic Resources". The results are shown in Table 2 below.
[0050] Table 2 Slaughter Indicators for Wuzhishan Ant Chicken
[0051] project Slaughter weight / % Slaughter rate / % Example 1 1032±124 93.2±1.1 Comparative Example 1 823±106 87.0±1.6
[0052] As shown in Table 2 above, compared with Comparative Example 1, the ant chickens of Example 1 have higher slaughter weight and slaughter rate. This indicates that by constructing a free-range activity area in the orchard and successively adding fluorescent LED lights in the chicken house and simultaneously adding fluorescent LED lights and blue LED lights in the straw sheds of the chicken house and free-range area, the ant chickens raised in this invention can quickly reach the level of high-quality chickens with good slaughter performance.
[0053] 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.
