When pig production is in a deficit period, every effort should be made to reduce costs. The rational addition of some inexpensive mineral additives in pig feed can promote growth and prevent pig diseases, and can save food, reduce costs, and greatly increase the economic benefits of pig production. Now introduce several commonly used pig feed additives for pig farms and pig farmers reference selection.
Coal ash
Coal ash slag not only contains the mineral elements required by pigs such as phosphorus, potassium, copper, iron, magnesium, zinc, and manganese, but also contains a new porcine growth regulator, humic acid. Feeding pigs with it can directly enhance the vitality of various enzymes, promote metabolism, and increase the accumulation of organic matter in the body. Adding 3% to 5% coal ash residue to pig diets can regulate salt and alkali in pigs, increase growth rate, reduce disease, and effectively prevent pig diarrhea, constipation, and asthma, and significantly reduce mortality.
Bentonite
Bentonite, commonly known as "white clay," contains not only the large amount of silicon and aluminum compounds, but also the mineral elements needed by more than 20 kinds of pigs such as phosphorus, potassium, copper, iron, magnesium, zinc, manganese, cobalt, chromium, calcium, barium, and titanium. . These elements are components of enzymes, hormones, and biologically active substances that can significantly alter the activity or immune performance of enzymes and hormones. First, bentonite has a good palatability and adsorption, can delay the speed of feed through the digestive tract, so that pigs can effectively use nutrients, improve the digestibility of the nutrients; Second, there are many special physical and chemical properties of bentonite, can be adsorbed pigs The harmful substances in the body inhibit the growth of pathogenic bacteria in the gastrointestinal tract, increase resistance, and promote growth and development. The third is to replace grain as a carrier of various trace elements to prevent the imbalance of calcium and phosphorus, participate in the metabolism and immune response of the body, and improve the survival of pigs. rate. Bentonite is generally good at adding 2% to 4% to pig diets.
Zeolite
Zeolite is a kind of natural silicate minerals. It contains the major elements and most of trace elements needed for the growth and development of 18 kinds of pigs such as calcium, phosphorus, iron and copper. It is an ideal natural mineral feed additive, and it is inexpensive. The interior of the hole has a crystal structure of multi-hole porous holes. The volume of pores (holes) accounts for more than 50% of the total volume of zeolite. It has strong adsorption force and can adsorb harmful gases such as methane, ethane and E. coli and Salmonella toxins in the intestine. , And can inhibit the growth and reproduction of harmful bacteria. If 3%~5% zeolite powder is added to the pig diet, the average weight gain of the pig can be increased by 10%; it can prevent diarrhea, contagious gastroenteritis, bronchitis and rickets in pigs, such as feeding sows can accelerate fetal growth Speed, prevent stillbirth, improve survival rate, save 70% of medical expenses, reduce odor, improve feeding environment. The water content of the pig's stool is reduced, and the column is clean and dry, which fully improves the hygiene of the pig farm and is beneficial to the growth and development of the pig.
Maifan Stone
Maifan Stone is a kind of natural health medicine stone with biological activity. It is a kind of rock with specific structure and trace element combination formed by weathering granite stone. One is that the metal elements contained in it are easily soluble in dilute acid. When it passes through the pig's stomach, it can release the contained elements and is directly used by pigs. Especially, the trace elements such as nickel, titanium and selenium are enzymes in the pig's body. The activating substances can increase the activity of enzymes and the utilization of feed nutrients. The second is that Maifanshi has good adsorption and ion exchange, and it can selectively adsorb bacteria in the digestive tract of pigs and play a role in disease prevention. It is advisable to add 1% to 3% of maifan stone in pig diets.
other
The yellow clay below one meter deep in yellow clay mountain areas and hilly areas contains not only a large amount of iron and copper compounds but also more than 20 kinds of mineral elements required by pigs. Adding 2% to 4% of yellow clay in pig diets has a significant effect on increasing appetite, increasing weight gain and preventing disease.
Nitrate in the pig's feed by adding 0.5% to 0.6% of niobium nitrate, daily gain increased by 20%, feed utilization increased by 15%, and the pig health and disease, fur light, strong appetite, normal urine.
The addition of 0.25% copper sulphate to copper sulphate in pig feed can increase pigs' daily weight gain by 16%, feed utilization rate by 5%, and feed cost by about 4%.
Zinc sulfate added 10 mg to 20 mg per piglet per day, and 30 mg to 50 mg for big pigs, so that pigs have good appetite, smooth fur, less incidence, and faster growth.

Companies registered capital of 35 million yuan, the end of 2014 the total assets of 48.69 million yuan, including fixed assets of 37.52 million yuan. The company's existing cooperation Orange cultivation base 7043.5 acres, the company production base is located in Jiangxi County Tech Industrial Park Chu Tan industrial area, covers an area of 120 acres, it has built a standard plant 9,000 square meters, Nissan 6000 kg Orange enzymes and other liquid enzyme products. Enzyme, known as enzyme, refers to a polymer substance having biocatalytic functionality. In the catalytic reaction system an enzyme, the reactant molecules are known as substrates, enzyme substrates by catalytic conversion to another molecule. Almost all cellular activity of enzymes involved in the process are required to improve efficiency. Similar to other non-biological catalysts, enzymes chemical reactions by lowering the activation energy to accelerate the rate of the reaction, most of the enzyme catalyzed reaction rate can be increased a million times; in fact, the enzyme is to provide an activation energy needs than another low way, so that more particles to have less than the activation energy of the reaction kinetic energy, thus speeding up the reaction rate. Enzyme as a catalyst, in itself is not consumed during the reaction, it does not affect the chemical equilibrium reactions. Positive enzyme catalysis, but also a negative catalytic effect, not only to accelerate the reaction rate, but also to reduce the reaction rate. And other non-living catalysts is different, having a high degree of specificity of enzyme, only a catalytic reaction or produce a particular specific configuration.
