A low-copper and antibiotic-free compound premix for pigs

Abstract

The invention relates to a low-copper and antibiotic-free compound premixed feed for pigs. The compound premixed feed includes per kilogram: 3.38-3.63g of compound vitamins, 19-42g of compound trace elements, and 2.5-10.5g of compound enzymes for pigs , choline chloride 4.5‑15.75g, lysine 50‑125g, mold adsorbent 25‑94.5g, rice husk powder 19‑26.25g, ethoxyquinoline 3.95‑4.05g, phytase 1.2‑1.8g , salt 30‑45g, stone powder 50‑70g, calcium hydrogen phosphate 55‑75g, sweetener 3.8‑4.2g, fragrance 0.95‑1.05g, chitosan oligosaccharide 1.5‑2.5g, green tea powder 1.5‑2.5g, yeast selenium 1.5g. No antibiotics are added to this feed, which greatly reduces the amount of copper used, making it easier to degrade or ferment organic matter such as pig farm manure. Under the premise of environmental protection, it produces safe pork without antibiotics, and improves the quality and flavor of pork .

Description

technical field [0001] The invention relates to the technical field of animal husbandry feed, in particular to a low-copper and antibiotic-free compound premix for pigs. Background technique [0002] The modern pig industry is inseparable from the compound premix in the feed. The so-called compound premix is ​​a homogeneous mixture prepared by preparing multiple additives of the same type or different types of additives in a certain proportion. The amount of compound premix in full-price feed is relatively small (0.5% to 10%), mainly to supplement nutrition, promote growth, prevent diseases, and improve breeding benefits. Although the amount is small, it can improve animal production performance. , The improvement of feed conversion ratio has a great effect. [0003] At present, most of the compound premixes for pigs actually used in pig farms contain one or several kinds of antibiotics. At different stages of pig growth and finishing, the compound premixes containing diffe...

Problems solved by technology

However, high-copper feed has many hazards. First, there are residues in pork and pig viscera, which endangers food safety. Second, high-copper pig manure seriously pollutes the environment. The fertilizer made of this kind of pig manure causes metal pollution to the soil after use.

The 1224 document published by the state in 2010 stipulates that the copper in the full-price feed of 30-60kg growing pigs shall not exceed 160ppm, and the copper in the full-price feed of 60kg fattening pigs shall not exceed 35ppm. However, reducing the copper content requires the entire feed formula. Adjustment, because the work of adjusting the formula is a technical research, and the feeding effect is not necessarily good, so in order to pursue the maximum benefit, in the absence of the best substitute, farmers are still willing to choose high-copper feed. In order to meet market demand, the feed The phenomenon of excessive use of copper sulfate in the middle of the country is still very common

[0005] Moreover, due to the excessive pursuit of growth performance in nutrition in the current breeding process, the animal body is therefore faced with excessive oxidative stress. Therefore, slaughterhouses and consumers have reported that the current pork quality is low, the meat color is white or dark, and the flavor is poor. and many more

In order to improve the quality of pork, feed companies and breeding companies have also thought of many ways, but just like the above-mentioned situation of using antibiotic substitutes, since the livestock and poultry body is an organism composed of different cells, it is only necessary to use a certain raw material for a certain problem , is not enough to build a healthy, normal, and active cell organism. Only by eliminating free radicals, the root cause of oxidation, and building healthy cells can truly improve meat quality
