Embodiment 1

[0083] When caged laying hens are raised to the age of 72 weeks, stop feeding the feed for laying hens and change to feed the feed described in the present invention. In parts by weight, the composition of the feed is as follows: 65 jin of corn, 25 jin of rice distiller's grains, pineapple residue 5 catties, sugar palm pith powder 3 catties, yeast hydrolyzate 2 catties, squid powder 3 catties, oregano oil 0.05 catties, salt 0.2 catties, yeast selenium (selenium content 2000mg / kg) 0.02 catties, Bacillus subtilis ( ≥20 billion pieces / gram) 0.05 catties. Routine management in the original cage, free access to food, and then feeding for 3 weeks, that is, nutrition-enhanced selenium-enriched chicken.

Embodiment 2

[0085] When the caged laying hen is raised to 74 weeks of age, stop feeding the laying hen feed, and change to feed the feed of the present invention. In kg by weight, the composition of the feed is as follows: 70kg of corn, 30kg of rice distiller's grains, 3kg of pineapple residue, Sugar palm pith powder 2kg, yeast hydrolyzate 1.2kg, squid powder 2kg, oregano oil 0.01kg, salt 0.1kg, yeast selenium (selenium content 2000mg / kg) 0.01kg, Bacillus subtilis (≥20 billion / gram ) 0.02kg. Change from cage breeding to free-range breeding in mountainous areas with a density of 400-500 per mu of land, increase the amount of exercise, routine management, free feeding, and then rearing for 4 weeks, that is, nutrition-enhanced selenium-enriched competition native chicken.

Embodiment 3

[0087] When the caged laying hen is raised to the age of 74 weeks, stop feeding the laying hen feed, and change to feed the feed of the present invention. In kg by weight, the composition of the feed is as follows: 60 kg of corn, 10 kg of rice distiller's grains, 10 kg of pineapple residue, Sugar palm pith powder 1kg, yeast hydrolyzate 0.5kg, squid powder 5kg, oregano oil 0.1kg, salt 0.3kg, yeast selenium (selenium content 2000mg / kg) 0.05kg, Bacillus subtilis (≥20 billion / gram ) 0.03kg. Changed from cage breeding to 400-500 free-range chickens per mu of land, increasing the amount of exercise, routine management, free feeding, and then feeding for 5 weeks, that is, nutritionally enriched selenium-enriched competition native chickens.

Abstract

The invention relates to a breeding method of nutritionally fortified selenium-enriched chickens. The breeding method of the nutritionally fortified selenium-enriched chickens comprises the steps thatspent chickens of laying hens are selected to continue to breed; in the process of continually breeding, the chickens are fed nutritious feed, and the continual breeding time is 3-5 weeks; the nutritious feed comprises energy feed, crude fiber feed, protein feed, traditional Chinese medicine feed, selenium-rich feed, microecological preparation and mineral feed; and each feed is prepared from thespecific components as follows(by weight): the energy feed is prepared from 1-3 parts of sugar plum pith powder and 60-70 parts of corn; the crude fiber feed is prepared from 20-30 parts of rice vinasse and 5-10 parts of pineapple dregs; the protein feed is prepared from 0.5-2 parts of yeast hydrolysate and 2-5 parts of squid powder; the traditional Chinese medicine feed is prepared from 0.01-0.1part of oregano oil; the selenium-rich feed is prepared from 0.01-0.05 part of selenium yeast; the microecoligical preparation is prepared from 0.02-0.05 part of bacillus subtilis; and the mineral feed is prepared from 0.1-0.3 part of salt. The breeding method of the nutritionally fortified selenium-enriched chickens can reduce the loss of nutrition, is convenient for the blending of the feed, and is especially suitable for large-scale and standardized automatic production and use of farms.

Description

technical field [0001] The invention relates to nutritional edible poultry, in particular to a breeding method for nutritionally fortified selenium-enriched chicken. Background technique [0002] Chicken has high protein content, rich amino acids, high digestibility, easy to be absorbed and utilized by the human body, low fat content, and contains more unsaturated fatty acids and phospholipids, collagen, vitamins, and calcium, phosphorus, iron, copper , zinc and other minerals. Every 100 g of chicken contains 19.3g of protein and 9.40g of lipid, which belongs to low-fat and high-protein food. [0003] At present, the chickens sold in the market are mainly white-feathered broilers, which are characterized by fast growth and low food consumption. The average weight of 6-week-old chickens is about 2.75 kg. Due to the short breeding time and high breeding density, although the price is low, the quality of chicken meat is difficult to meet the needs of high-end consumers. With...
