Feed additive for livestock and poultry and preparation method thereof

Abstract

The present invention discloses a feed additive for livestock and poultry. The feed additive is characterized by being prepared from the following raw materials in parts by weight: 5-15 parts of rareearth, 40-60 parts of lysine, 40-60 parts of white vinegar at 9 degrees of acidity, 110-310 parts of biochemical fulvic acid potassium and 80-100 parts of a filler. The product enables broiler chickens to conduct slaughtering at seven weeks by a feeding experiment; average body weight is 2.42 kg; a feed conversion ratio is 2.05:1; weight gain is increased by 6.8%; a feed utilization rate is increased by 6.5%; a daily weight gain of pigs is increased by 22.5%; and the feed conversion ratio is reduced by 20.3%.

Description

technical field [0001] The invention relates to the field of feed, in particular to a livestock and poultry feed additive and a preparation method thereof. Background technique [0002] With the progress of society, people's living standards are improving day by day, and the livestock and poultry industry has also developed and grown, and higher requirements have been put forward for livestock and poultry feed. Studies have shown that antibiotics can promote the growth of livestock and poultry and prevent diseases, so some feed manufacturers In order to one-sidedly pursue the feed effect and meet the needs of some farmers, a large amount of antibiotics are added to the feed. Some manufacturers even add some high-residue antibiotics to the feed in order to improve the growth rate of livestock and poultry and prevent diseases. , chemical elements that may cause toxic and side effects to humans, livestock and poultry, and prohibited drugs such as β-adrenaline and diazepam.

[0002] With the progress of society, people's living standards are improving day by day, and the livestock and poultry industry has also developed and grown, and higher requirements have been put forward for livestock and poultry feed. Studies have shown that antibiotics can promote the growth of livestock and poultry and prevent diseases, so some feed manufacturers In order to one-sidedly pursue the feed effect and meet the needs of some farmers, a large amount of antibiotics are added to the feed. Some manufacturers even add some high-residue antibiotics to the feed in order to improve the growth rate of livestock and poultry and prevent diseases. , chemical elements that may cause toxic and side effects to humans, livestock and poultry, and prohibited drugs such as β-adrenaline and diazepam. Long-term use of antibiotics in feed destroys the normal microbial flora in the gastrointestinal tract on the one hand and leads to drug-resistant strains The increase of the drug effect decreases, on the other hand, it is harmful to human health

In recent years, people have not given up the research and development of alternatives that can replace antibiotic feed additives for livestock and poultry, such as probiotics, oligosaccharide preparations, enzyme preparations, and saponins. However, due to poor stability or inconsistent effects, antibiotics have not been completely replaced. For this reason, the patent application number is CN201110202715.1, which discloses a pig feed additive. 10-30 parts of lanthanum acid, 10-30 parts of cerium citrate, 10-50 parts of potassium fulvic acid, 0.1-5 parts of EDTA, and 0.1-5 parts of citric acid. problem, but the cost of separation and purification of lanthanum and cerium is high, lanthanum citrate and cerium citrate are easy to deteriorate during storage and produce some substances that cannot or are difficult to absorb by the body, the palatability of traditional Chinese medicine formula is poor, the content of fulvic acid is low, and potassium fulvic acid complex The synthesizing ability is weak, and the high content of rare earth elements inhibits the activity of beneficial microorganisms and related enzymes, so its effect is limited
