[0002] At present, most markets have higher requirements for the fullness of color of livestock and poultry products. The livestock and poultry products with bright color are favored by consumers, and the color of the products directly affects the purchasing desire of consumers and the economic value of the livestock and poultry products. The yellow-feathered broiler is a matching system used in the south of China, and is favored by consumers. Consumers require yellow skin, yellow shank and yellow fat when selecting and purchasing yellow-feathered broiler products. However, poultry cannot synthesize pigments by itself and must obtain and deposit pigments in the body from feed, and it is difficult to achieve the coloring requirement by relying on natural pigments in feed raw materials only. Therefore, coloring agents are often added to poultry feed to improve the appearance and commodity value of the products.

[0003] The coloring agents are mainly derived from artificial synthesis and natural extraction. Long-term addition of chemical synthetic pigments can easily cause cancer and teratogenicity, and affect the health of consumers. Natural pigments extracted from medicinal plants, vegetables, fruits and microorganisms are favored by consumers due to their greenness and safety. The addition of such natural pigments in poultry feed not only has a coloring effect, but also has the effects of disease resistance and health care.

[0004] In view of this, the present application is proposed. SUMMARY

[0034] Experimental Example 1 The present experimental example tests the growth performance of yellow-feathered broilers.

[0035] Test design: 180 healthy 1-day-old yellow-feathered broilers were randomly divided into 3 groups, 6 cages per group, 10 broilers per cage (half male and half female). The control group was fed with the basic diet; the test groups were respectively fed with the basic diet + 500 g / t and the basic diet + 1000 g / t of the feed additive. The test period was 56 days, divided into two stages: the brooding period (1-28 d) and the growth period (29-56 d), with feeding at 08:00 and 17:00 every day, and the chickens freely ate and drank water. Each cage of chickens was weighed at 08:00 on the 1st, 29th, and 57th days of the test, and the feed intake of each cage of chickens was recorded throughout the test. The test chickens were raised in three-layer wire cages with free access to feed and water. The basic diet was prepared and the nutritional level was referred to the "Broiler Feeding Standard" (NY 33-2004) (Table 1).

[0036] Table 1 Composition and nutritional level of the basic diet

[0037] Note: The vitamin and mineral premix provides the following per kilogram of basic diet: vitamin A 1200 IU, vitamin D3 500 IU, vitamin B1 3.0 mg, vitamin B2 8.0 mg, vitamin B6 7.0 mg, vitamin B12 0.3 mg, vitamin E 20 mg, vitamin K 0.5 mg, folic acid 0.5 mg, biotin 0.1 mg, calcium 1.5 g, phosphorus 0.8 g, sodium 0.2 g, potassium 0.6 g, magnesium 0.2 g, iron 50 mg, zinc 50 mg, copper 5 mg, manganese 50 mg, iodine 0.5 mg, selenium 0.2 mg, and cobalt 0.2 mg. 120.03 mg, pantothenic acid 20.0 mg, biotin 0.1 mg, folic acid 1.5 mg; ferrous sulfate 96 mg, copper sulfate 25 mg, potassium iodide 0.9 mg, zinc sulfate 98 mg, manganese sulfate 105.4 mg and sodium selenite 0.04 mg.

[0038] Test results: As can be seen from Table 2, at the 1-day-old stage, the average body weight (BW) of the yellow-feathered broilers in the three groups had no difference; compared with the control group, the group with 1000 g / t feed additive added improved the average daily gain (ADG) and average daily feed intake (ADFI) of the yellow-feathered broilers from 1 to 28 days; compared with the control group, the groups with 500 g / t or 1000 g / t feed additive added improved the ADG and ADFI of the yellow-feathered broilers from 29 to 56 days; the groups with 500 g / t or 1000 g / t feed additive added improved the final body weight (BW) and ADG of the yellow-feathered broilers and reduced the feed-meat ratio (F / G).

[0039] In summary, the above results show that adding 500 g or 1000 g of the feed additive per 1000 kg of yellow-feathered broiler feed (i.e. the basic diet) can improve the growth performance of the yellow-feathered broilers.

[0040] Table 2 Growth performance of yellow-feathered broilers

[0041] Experimental Example 2 Test of the yellowness value of the shank diameter, skin and muscle of the yellow-feathered broilers.

[0042] Test design: same as Experimental Example 1. The control group was the basic diet, the lycopene group was the basic diet + 30 g / t lycopene, test group 1 was the basic diet + 500 g / t of the feed additive provided in Example 1, and test group 2 was the basic diet + 1000 g / t of the feed additive provided in Example 1. On the 57th day of the test, one male and one female were selected from each cage for slaughter. The yellowness value (b*) of the skin and meat of the yellow-feathered broilers was measured using a CR-10 colorimeter, and the shank diameter, back skin and chest skin of the yellow-feathered broilers were scored using a Roche color fan (Roche Yolk Colour Fan, RYCF).

[0043] Test results: The yellowness value (b*) of the skin, breast muscle and leg muscle of the yellow-feathered broilers in the groups with 500 g / t or 1000 g / t feed additive added was significantly higher than that of the control group; the beak, shank diameter and skin scores of the yellow-feathered broilers in the groups with 500 g / t or 1000 g / t feed additive added were significantly higher than those of the control group (Table 3, Figure 1 and Figure 2 ).

[0044] In summary, the feed additive was added to 500 g or 1000 g per 1000 kg yellow-feathered broilers, which significantly improved the color of yellow-feathered broilers.

[0045] Table 3 Foot diameter and skin redness (a*) and yellowness (b*) of yellow-feathered broilers

[0046] Experimental Example 3 Test of antioxidant capacity.

[0047] Test design: same as experimental example 1. On the 57th day of the test, one male and one female were selected from each cage, and were slaughtered. The chicken breast was separated, the total protein content of the sample was determined by BCA kit, and the antioxidant indexes in the sample were determined by total superoxide dismutase (T-SOD), glutathione peroxidase (GSH-Px), malondialdehyde (MDA) and total antioxidant capacity (T-AOC) kits. All kits were provided by Nanjing Jiancheng Biological Engineering Institute.

[0048] Test results: as shown in Table 4, the total antioxidant capacity of the breast muscle of yellow-feathered broilers in the group added with 500 g / t or 1000 g / t feed additive was significantly improved; the lipid peroxidation of the breast muscle of yellow-feathered broilers in the group added with 500 g / t or 1000 g / t feed additive was significantly reduced.

[0049] In summary, the feed additive was added to 500 g or 1000 g per 1000 kg yellow-feathered broilers (i.e. the basic daily ration), which improved the antioxidant capacity of yellow-feathered broilers.
