Embodiment 1

[0026] A selenium-enriched feed for broiler chicks in the late stage of fattening, comprising the following components in parts by weight: 30 parts of corn, 10 parts of bran, 6 parts of barley germ, 20 parts of sweet potato sprouts, 8 parts of lotus root starch, 3 parts of medical stone, fried 6 parts of soybean powder, 8 parts of watermelon seeds, 4 parts of foxtail seeds, 4 parts of duck egg shell powder, 0.3 parts of salt, 0.4 parts of allicin, 0.3 parts of sesame oil;

[0027] Wherein, the sweet potato sprouts are obtained by cutting and planting sweet potato stems. The specific operation steps are: wash the sweet potato stems and soak them in water at 45-50°C for 15-20 minutes, take them out and put them into a medical stone for frying. Soak in the cooking liquid for 50-60 minutes, then plant cuttings in the greenhouse, spray the sodium selenite aqueous solution with a concentration of 22-25μg / m to moisturize, keep the temperature in the greenhouse at 25-28°C, and the ligh...

Embodiment 2

[0037] A selenium-enriched feed for broiler chicks in the later stage of fattening, comprising the following components by weight: 25 parts of corn, 14 parts of bran, 7 parts of barley germ, 12 parts of sweet potato sprouts, 8 parts of lotus root starch, 5 parts of medical stone, fried 5 parts of soybean powder, 15 parts of watermelon seeds, 4 parts of foxtail seeds, 4 parts of duck egg shell powder, 0.2 parts of salt, 0.4 parts of allicin, 0.4 parts of sesame oil;

[0038] Wherein, the sweet potato sprouts are obtained by cutting the top tender stems of sweet potatoes, and the specific operation steps are: wash the top tender stems of sweet potatoes, soak them in 45-50°C water for 15-20 minutes, take them out and put them into wheat rice Soak in the stone decoction for 50-60 minutes, then plant cuttings in the greenhouse, spray the sodium selenite aqueous solution with a concentration of 22-25 μg / m to moisturize, keep the temperature in the greenhouse at 25-28°C, and the light...

Abstract

The present invention discloses a selenium enriched feed of young broiler chickens in late fattening period and a preparation method thereof. The selenium enriched feed comprises the following components: corn, wheat bran, barley germs, sweet potato buds and seedlings, lotus root starch, medical stones, stir-fried soybean flour, watermelon seeds, setaria viridis seeds, duck eggshell powder, edible salt, allicin, and sesame seed oil. Compared with the prior art, the feed has the following advantages: by a reasonable proportion of the raw materials, metabolizable energy in the feed is appropriately increased, protein contents are reduced, nutrition is balanced, feed cost is reduced, the weight gains of the young broiler chickens are ensured, and the improvements of the contents of selenium and other nutrients in the feed by adding expensive selenium-enriched coarse cereals are avoided. The sweet potato stem segments or top end tender buds are used to conduct biotransformation of inorganic selenium in the medical stone and sodium selenite solution, so that the available selenium content in the feed is improved, the selenium content in the chicken meat is about 0.4 mg / kg, the young chickens are better in tastes, and the feed has efficacies of enhancing strength and preventing diseases in a long-term consumption.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to a selenium-enriched feed for broiler chicks in the later stage of fattening and a preparation method thereof. Background technique [0002] my country's broiler chicken industry is the fastest growing emerging industry in animal husbandry. The nutritional content of young chicken meat is high, and its protein content is much higher than that of old chicken meat. Young chicken meat contains less elastic connective tissue and is easily eaten Absorbed by the digestive organs of the human body. Since most areas of our country belong to selenium-deficient areas, it is a huge project to supplement selenium to the human body. Since chickens are easily absorbed and utilized by the human body, the three-stage feeding method of broiler chickens can be adjusted according to each During the different growth stages, feeds are formulated according to different growth re...
