technical field

The invention belongs to the technical field of feed, and in particular relates to a preparation method of a sugar and physalis-coated soft particle feed.

Background technique

China is a country with a large population and a large country in the breeding of ruminants such as cattle and sheep. In 2018, my country sold 719 million live pigs, including 48 million sows, and pork production reached 54.06 million tons. In 2019, the output of pigs, cattle, mutton and poultry was 76.49 million tons, down 10.2% from the previous year. Among them, the output of pork was 42.55 million tons, a decrease of 21.3%, the output of beef was 6.67 million tons, an increase of 3.6%; the output of mutton was 4.88 million tons, an increase of 2.6%; the output of poultry meat was 22.39 million tons, an increase of 12.3%; the output of poultry eggs was 33.09 million tons, an increase of 2.6%. An increase of 5.8%; milk output was 32.01 million tons, an increase of 4.1%. In 2019, the total output of commercial feed in my country will reach 239 million tons, including 198 million tons of compound feed, 25 million tons of concentrated feed, and 6.35 million tons of additive premixed feed, of which more than 8 million tons of sow feed. It is estimated that by 2025, the national compound feed output will reach more than 300 million tons, of which sow feed will reach more than 10 million tons.

In the past two decades, my country's full-price feed is basically hard pellets. Hard pellets are feeds that refer to pelleted feeds with a moisture content of less than 12% made by crushing, mixing, conditioning and pelleting feed raw materials. As we all know, the following problems commonly exist in pellet feed in the young livestock and poultry breeding industry, especially in piglet breeding: First, for piglets, calves and lambs, hard pellet feeds have high hardness, large dust and poor palatability. , low feed intake, easy diarrhea. Young livestock and poultry, especially suckling piglets, need pellet feed with high water content, high nutrition, good food attraction, soft pellets and no dust. poor and severe diarrhea. Due to severe diarrhea, a large amount of antibiotics must be added to the feed, and the harm of feeding antibiotics to humans is known to women and children, and their use has been gradually banned. Second, when feeding hard pellets, it is easy to generate dust, which can easily cause lung inflammation and discomfort in livestock and poultry, and must be accompanied by a large amount of drinking water. Third, although the liquid feed is very palatable, and livestock and poultry like to eat, but its storage, packaging and transportation costs are high (caused by too high water content, the water content is more than 80%), easy to contaminate bacteria, not resistant to storage, It is easy to cause the problem of animal diarrhea. At present, there are also studies to try to prepare soft pellet feed, which is mainly used in aquatic animals, and there are few studies or reports on soft pellet feed for livestock and poultry. In general, soft pellets also have four major problems: one is that it is easy to stick to form agglomerates during transportation, and it is difficult to transport long distances (it will form agglomerates outside 5 highways); the other is that the water content is 25-50%, It is easy to be mildewed and difficult to store and store; third, it cannot enter the existing pellet feed feeding line, which is very inconvenient to feed; fourth, there is also a patent application for spraying syrup on the soft particles, but the surface of the soft particles coated with syrup is not When sprayed with adsorbed dry powder feed, it will stick together into a group after shaking, and it is impossible to transport and feed it at all. Therefore, since the beginning, the development of soft pellet feed products with high water content (25-50% water content), good palatability, large feed intake, high digestibility, low diarrhea rate, no mildew and easy preservation has been It is the goal pursued by the feed industry and the breeding industry.

Fishmeal is made from the by-products of whole fish processing such as head, fins, bones, tails, viscera, etc. The protein is of good quality and rich in various essential amino acids, such as lysine, tryptophan, methionine, cystine, etc. The content of arginine is relatively low, which is opposite to the amino acid composition of most plant-based feeds. It is synergistic when used in combination with plant-based feed ingredients. Fishmeal also contains vitamin A, vitamin D, vitamin E, etc., but it is easily destroyed when processing and storage conditions are poor. The content of calcium and phosphorus in fish meal is high, and the proportion is appropriate. It is also high in selenium, iodine, zinc, iron, and contains moderate amounts of arsenic. Fishmeal contains unknown growth-promoting factors that stimulate animal growth and development.

Molasses is a kind of high-quality and low-cost liquid feed material. It is the thick liquid left after the sugar cane juice is squeezed out by the sugar industry, after heating, neutralization, precipitation, filtration, concentration, crystallization and other processes. It is moldy, does not stain bacteria, mainly contains sucrose, and the pantothenic acid content in sucrose molasses is high, up to 37mg/kg, and the biotin content is also considerable. Rich in sugar and protein, it can provide energy, vitamins and other substances for animals; it has a sweet taste and improves the palatability of feed; it reduces feed dust and improves the quality of pellet feed. Therefore, it can be used as an auxiliary material or additive for ruminant feed. Efficient and green. Now domestic feed mills have also begun to widely use molasses.

Citric acid is a white crystal like sugar. It is made from corn as the main raw material and is extracted and refined by a series of chemical processes such as fermentation. Its solubility is extremely high, and it can be directly absorbed and metabolized by organisms. A large number of studies at home and abroad have proved that citric acid has the best effect as a feed acidulant. Scipionic et al. compared the addition of citric acid, fumaric acid, and malic acid to feed, and found that citric acid was the most effective in reducing coliform bacteria and anaerobic bacteria. With the standardized development of the anti-antibiotic trend in the feed industry, the application of organic acids in feed is more and more extensive. Citric acid has the advantages of non-toxicity and no residue. It can promote mineral absorption, improve feed utilization, ensure feed quality, and delay feed oxidation. Therefore, it has been widely used in breeding.

Benzoic acid is often used as a drug or preservative to inhibit the growth of fungi, bacteria and molds. Benzoic acid has been registered as a feed additive for many years. After benzoic acid enters the body, it combines with glycine in the liver to form hippuric acid and is excreted in the urine. Due to its special metabolism, the addition of benzoic acid to the diet can effectively reduce the pH of animal urine, help prevent urinary tract infections and endometritis, and be beneficial to the reproductive performance of the body. Adding benzoic acid to the feed can also adjust the intestinal microecological balance and promote growth.

The feed industry develops a feed that has high digestion and utilization rate, saves raw materials, good palatability, high feed intake, is beneficial to animal health, and is not easy to be infected with bacteria and viruses.
