What animal is the trace element manganese suitable for?

There are very few trace elements in all living things that you can't change, but they're one of the most important sources of energy and there are many kinds of trace elements, manganese is one of them but, although trace elements are important, they're not very good.Not all organisms need to supplement trace element manganese. This article will explore the trace element manganese.

The main points of this paper are as

  • Introduction of trace element manganese

  • What animal is suitable for?

  • Matters needing attention


1. Introduction of trace element manganese

The manganese source currently used most is manganese oxide, in addition to manganese sulfate, manganese carbonate, manganese methionine, manganese protein salt and the like.

Manganese is distributed in all tissues of aquatic objects with the highest content in bones. Trace element manganese is mainly concentrated in mitochondria and is an activator of many enzymes; it is also a component of arginine, pyruvate decarboxylase and superoxide dismutase, and plays an important role in the tricarboxylic acid cycle.

Trace element manganese has a good effect on animal growth, development, reproduction, and certain secretory functions. Manganese deficiency in manganese is characterized by slow growth, infertility, short bones and so on. Manganese sulfate is often added to the feed to supplement manganese.

The physiological function of trace element manganese is very extensive and is essential for the normal growth of bone. Manganese is related to the activity of polysaccharide polymerase. Polysaccharide polymerase can catalyze uridine diphosphate-N-acetyl-galactosamine and uridine diphosphate- Glucuronic acid is combined into a polysaccharide, and mucopolysaccharide is an important component of cartilage and cartilage tissue, so bone deficiency can be caused in the absence of manganese. Manganese is a component of many enzymes in the body and plays an important role in the metabolism of proteins, carbohydrates and lipids. Manganese has a promoting effect on weight gain. Adding 40 mg/kg of manganese to the feed can increase the daily gain and feed utilization rate of growing pigs. Manganese can promote the development of gonads, stimulate the synthesis of cholesterol in the body, thereby improving the reproductive performance of breeding pigs. In addition, manganese is also involved in hematopoiesis. The mechanism may be that manganese improves the body's utilization of copper, while copper regulates the body's use of iron. Copper and iron promote red blood cell production, maturation and release, thereby indirectly participating in hematopoiesis. .


2. What animal is suitable for?

  • Pig

At present, manganese is often used as an additive for growing pigs and breeding sows to increase lean meat rate and reduce body thickness, increase sow conception rate, piglet birth weight and piglet weaning survival rate. Christianson (1990) et al reported that piglets fed the 10-20 mg/kg diet manganese group were significantly more likely to have a significant difference than the 5 mg/kg diet manganese group, and helped to improve sow estrus.

  • Fish

If the manganese content in the feed is insufficient, the growth is poor, the tail of the rainbow trout is shortened, and the enzyme activity is decreased. The requirement for manganese in rainbow trout is 12-13 mg/kg. When the feed contains 2.4mg/kg of manganese, it can meet the needs of the channel catfish. Low-manganese broodstock with high mortality and low hatching rate. The utilization rate of manganese in fish meal is very high, and it is not affected by the content of tricalcium phosphate. However, manganese in fish meal can not meet the nutritional needs of carp. Adding 13mg/kg of manganese to carp feed can improve Growth rate to prevent bone formation from being blocked. The optimum requirement for grass carp for manganese is 15 mg/kg feed. In the semi-intensive system, tilapia feed does not have to be added separately due to sufficient manganese obtained from natural foods and water. Shrimp does not require manganese, and 3 mg/kg of manganese in the feed inhibits the growth of the shrimp. The requirement for manganese in feed for general cultured fish is 13 mg/kg.


3. Matters needing attention

The demand for manganese in growing and finishing pigs varies from country to country. It is generally believed that there is no deficiency in the feed containing 3-4 mg/kg of manganese. However, in the case of chronic manganese deficiency, it will lead to stagnant growth of pigs, skeletal deformities, and sow reproductive disorders. Pigs are not tolerant to manganese.

The maximum limit of manganese in pig feed is 400 mg/kg. If the amount of manganese reaches 500mg/kg, it will cause symptoms of poisoning. If it contains 2000mg/kg, it will cause hemoglobin to drop or even die.

The optimum requirement for grass carp for manganese is 15 mg/kg feed.

Semi-intensive tilapia, which is generally available in natural foods and water, is not necessarily added to the tilapia feed.

Shrimp does not require manganese, and if the daily intake of manganese in the shrimp is higher than 3 mg/kg in the bait ratio, the growth of the shrimp is inhibited.

Excessive manganese can cause fish movement disorders

The information on trace element manganese is as described above. If you understand the above knowledge, you can have more knowledge about manganese. It is more convenient to use, avoiding the loss caused by mistakes, and let the trace element manganese bring the greatest benefit to your farm.
