Briefly describe feed grade manganese sulfate and its application in animal growth

Abstract: This paper briefly introduces the characteristics, production process and application of feed-grade additive  manganese sulfate  in animal growth.

1. Characteristics of feed-grade additive manganese sulfate

The feed-grade additive manganese sulfate is very soluble in water, and can form 1-7 crystal aquatic products under different conditions . The feed-grade additive manganese sulfate is generally selected as manganese sulfate monohydrate , which is pink crystal with a relative density of about 3.5 and a melting point of 700 ℃ , and is insoluble in ethanol. The trace element manganese exists in animal body tissues, with higher concentrations in liver, bone, pancreas, etc., but in poultry and livestock, only liver, spleen and bone are more abundant. The correlation coefficient between feed-grade manganese and bone manganese was above 0.95 .

The absorption rate of trace element manganese by poultry and livestock is relatively low, generally around 1-4% . The absorption of trace element manganese depends on the absorption of bile salts, and the balance of manganese in the body is mainly achieved by excretion.

2. The function of manganese in animal body

The trace element manganese is involved in the metabolism of three major substances through the action of enzymes in animals. Manganese is involved in the formation of chondroitin sulfate, which constitutes the bone matrix. Chondroitin sulfate is a component of the organic matrix mucopolysaccharide, and the blockage of its synthesis will seriously affect the osteogenesis of cartilage in the body. The lack of trace element manganese in animals will seriously affect bone development, and also show symptoms such as reproductive function. The female estrus is not obvious, the cycle is chaotic, etc., the pregnancy is prone to miscarriage, the embryonic development is abnormal, and the mortality rate is low. Male animals, on the other hand, have abnormally developed sexual organs and poor sperm count and quality. The lack of trace element manganese also has a significant impact on animal growth and development. Manganese deficiency will lead to lower animal feed conversion rate and lower animal growth rate.

3. The production process of feed-grade additive manganese sulfate

With the continuous development of science and technology, our manganese smelting technology has also developed by leaps and bounds, and the demand for manganese is also increasing. my country's manganese resources are very limited, and the manganese products produced are of low grade, so the grade can only be improved by beneficiation, which not only increases the cost but also wastes resources. The current production process mainly includes dry method and wet method. The dry method requires high process temperature, large dust, poor working conditions, high requirements for manganese mining, and relatively stable product quality. The feed-grade additive manganese sulfate mainly adopts the wet method. Compared with the dry method, the wet method is more adaptable to low-grade manganese ore. Due to the gap between the process and production technology, the quality of the products produced by the wet method is also different.

In addition, different technological processes also have a great influence on the appearance of manganese sulfate. It is generally believed that the less crystallization water of manganese sulfate, the greater the temperature rise after manganese sulfate is dissolved in water, that is to say, many manganese content on the market is greater than or equal to 31.8 % manganese sulfate , its substance is high in impurities, and the temperature rises rapidly after being dissolved in water, and other nutrients in the feed lose activity due to its temperature, which has a great impact on the nutritional value of the feed itself.

In general, the current manganese sulfate production process has disadvantages such as low technological level, high energy consumption, high cost, and environmental pollution, so the production process can be further optimized.

4. Application of feed grade additive manganese sulfate in animal production

In general, livestock can obtain sufficient amounts of manganese in plant-based feeds so that no trace element manganese supplementation is required, while poultry must be supplemented with trace element manganese to meet the needs of the animal body, which may be due to the higher amount of impact in poultry , and the lack of manganese content in its feed ingredients. Feed grade additive manganese sulfate is a pink crystalline substance, odorless, soluble in water and glycerol, insoluble in alcohol. According to the national standard, the manganese content is ≥31.8% , and the health indicators such as lead, arsenic, and cadmium are also clearly stipulated. The lack of trace element manganese in animals mainly leads to the reduction of feed intake, slow growth, and poor feed utilization. Experiments have shown that in the process of hatching goose eggs and raising goslings to 15 days of age, those who are fed with the trace element manganese are obviously deficient in manganese. , stubby bones, difficulty walking, etc. There are also reports that feeding chickens with manganese-deficient basal diets has a 56.7% chance of leg disease . In addition, the trace element manganese is also an important part of various enzymes. Therefore, manganese can also participate in the synthesis of various proteins and amino acids through the action of enzymes in animals, and promote the synthesis of sex hormones. The trace element manganese is also closely related to hematopoietic function, and the liver is the most important hematopoietic organ in the embryonic stage. Of course, excessive manganese into the body can easily cause manganese poisoning, and it also has an accumulation effect on the damage to the immune system. Research reports show that by intravenous injection of manganese, it is found that the total number and activity of sperm in mice decrease with the increase of exposure.

1. Application of trace element manganese in poultry

The manganese requirement of poultry is much higher than that of the average mammal. When poultry is deficient in manganese, it is mainly manifested in abnormal bone development, stubby and curved leg bones, and lameness in sick chickens. This disease mostly occurs in 3-6 week old chicks. Underdeveloped, hatching rate is also reduced. Therefore, it is necessary to supply manganese to chickens. Laying hens and breeders are added in the proportion of 8g manganese sulfate added to 100kg of feed , which can meet the needs. Most birds and mammals have a high tolerance to excess manganese in the feed.

2. Application of trace element manganese in pig production

When pigs are deficient in the trace element manganese, the pigs will suffer from growth retardation, poor mammary gland development, prolonged estrus, neonatal piglets, ataxia, weak piglets, slow growth, and shortened tubular bones. However, the absorption rate of manganese in the diet is low, only 3%-4% , and the intake is excreted in the feces.

3. Application of trace element manganese in ruminants

The manganese content in ruminants is low, and the demand for manganese is not high. The general feed ration can basically meet the requirements, and the phenomenon of manganese deficiency is not easy to occur. When the level of manganese in the diet increased to 800ppm , it did not affect the growth and appetite of calves, but excessive manganese would affect the absorption of calcium and phosphorus by animals.
