Embodiment Construction

[0014] 1. Preparation of sodium selenite nutrient solution

[0015] Dissolve 12.5g sodium selenite (concentration 250ppm, the consumption of one mu of land) in 50kg water, add the tensio-active agent of 0.1~1% simultaneously, its effect is to make sodium selenite nutrient solution have good effect on ryegrass leaf surface Excellent wettability and adhesion to facilitate leaf absorption.

[0016] 2. Production of selenium-enriched ryegrass

[0017] When the ryegrass breaks through the soil and grows to 3-5cm, spray once on the leaves, and then spray again when it grows to 15-20cm, harvest when it reaches 30-40cm, apply fertilizer after harvesting, and spray when it regenerates to 3-5cm Once, spray again when it grows to 15-20cm, and harvest again when it reaches 30-40cm, until mature ryegrass is harvested. The green fresh ryegrass and mature ryegrass are dried for later use. Pay attention to the detection of selenium content in ryegrass. The selenium content in the selenium...

Abstract

The invention relates to a production method of selenium-enriched pork. A feed fed when live pigs are bred is a selenium-enriched nutritional feed processed by corn, wheat bran, soybean meal, fish meal, feed grade calcium hydrophosphate, mountain flour, trace elements and selenium-enriched ryegrass hay, wherein the content of the hay in the feed is not lower than 15wt%, and the selenium content in the hay is not less than 1,000mug / kg. The selenium-enriched ryegrass hay is obtained by drying ryegrass the reaped or harvested leaf surfaces of which are sprayed and applied with a sodium selenite nutrient solution the concentration of which is not lower than 200ppm. In the invention, the selenium-enriched pork is obtained by the two-time biotransformation of inorganic selenium and has ruddy meat color, tender quality, fragrant taste and no any fishy smell of a pigpen, the selenium content in each kilogram of pork is not less than 80mug, and the lowest selenium demand of a human body can bemet as long as an adult eats more than 100g of selenium-enriched pork every day.

Description

1. Technical field [0001] The invention relates to a production method of selenium-enriched nutritional poultry and livestock products, in particular to a production method of selenium-enriched pork. 2. Background technology [0002] In 1973, the World Health Organization (WHO) announced that selenium is an essential trace element in animal life. In 1994, my country promulgated the national standard GB14880-1994, allowing the addition of selenium in food as a food nutrition fortifier. In 2003, the U.S. Food and Drug Administration ( FDA) approved selenium as a tumor suppressor, allowing selenium nutritional products to label the tumor suppressor properties of human selenium. In recent years, people have become more and more aware of the important role of selenium in maintaining human life activities. Selenium is an important part of glutathione peroxidase, and at the same time it is an antioxidant, which can eliminate excessive free energy in the body. Selenium supplementati...
