Sulfate organic microelement-free special feed additive for suckling piglets and preparation method for special feed additive

Abstract

The invention relates to the technical field of feed additives, in particular to a sulfate organic microelement-free special feed additive for suckling piglets and a preparation method for the specialfeed additive. The special feed additive comprises the following raw materials in parts by weight: 30-80 parts of ferrous fumarate, 10-40 parts of zinc fumarate, 5-15 parts of manganese methionine, 5-15 parts of copper mothionine, 1-5 parts of pantothenic acid, 0.002-0.03 parts of calcium iodate, 0.001-0.03 parts of sodium selenite, 0.001-0.03 parts of cobalt methionine and 0.01-0.05 parts of compound vitamin. The special feed additive, prepared by employing the method, for the suckling piglets employs all-organic microelements, is free of sulfate ions, is also free of inorganic anions, is not bitter and astringent, has high product purity and good palatability, can maintain the balance of electrolytes of the piglets, effectively reduces the diarrhea rate of the piglets and meets the needs of growth of the piglets; and the feed additive is used in special feed for the piglets, and thus, the prepared feed has good palatability and a high absorption rate, effectively maintains the balance of electrolytes in intestinal tracts of the piglets, and can obviously increase average daily gain and reduce a feed conversion ratio.

Description

technical field [0001] The invention relates to the technical field of feed additive production, in particular to a special feed additive for suckling piglets containing no sulfate radical organic trace elements and a preparation method thereof. Background technique [0002] The health of piglets has been an important issue affecting the efficiency of pig farming for many years. Among all the factors that affect the health of piglets, piglet diarrhea can rank first. Diarrhea will lead to low feed remuneration, slow growth of piglets, stagnation of growth and development, severe Or even die, causing huge economic losses. Piglets have weak self-resistance, are sensitive to external stimuli, and are susceptible to pathogenic microorganisms and various stresses due to physiological characteristics such as imperfect development of the digestive tract, imperfect digestive enzyme system, insufficient gastric acid secretion, and variable intestinal microbial flora. Influenced by fa...

Problems solved by technology

If the electrolyte is unbalanced, it is very easy to cause a large loss of body fluids and electrolytes in the piglet, which will seep from the body and return to the intestinal tract, causing changes in the environment in the digestive tract, which will not only damage the fragile intestinal mucosa of suckling piglets, but also increase the risk of virus infection. It will also cause the water in the feces to increase, soften the feces, and cause diarrhea in piglets

Moreover, adding large doses of SO to the basic diet of piglets 4 2- , because sulfate has a bitter taste and is also pouring salt, which affects the palatability of suckling piglets, reduces feed intake and daily gain of piglets, and increases the use of sweeteners and lactose in the basic diet, thereby increasing feed costs

high doses of SO 4 2- It will also cause the activity of digestive enzymes in piglets to decrease, which will affect the digestibility of nutrients, which will reduce the weight gain and feed utilization rate of piglets, and it will have a destructive effect on vitamins in the diet, and it will also oxidize fat.

[0004] At present, in order to prevent and control diarrhea in suckling piglets, adding high-dose zinc oxide is a common behavior, but long-term use of high-dose zinc oxide has also caused widespread controversy in the industry, and the addition of zinc oxide to piglet feed is generally as high as 3000mg / kg The level of zinc has far exceeded the normal zinc requirement of piglets by nearly 30 times, indicating that it has nothing to do with its nutritional function, but it is used as an astringent, but its effect on the cause of diarrhea—intestinal damage and nutrient digestion The decline of absorption function and electrolyte imbalance have not solved the problem. Its use is a measure to treat the symptoms, not the root cause, with a certain degree of blindness.

Adding high doses of zinc oxide to piglet diets has also produced a series of problems: long-term use will cause severe dehydration of piglet intestinal mucosal epithelial cells, decreased nutrient digestion and absorption functions, and decreased body immunity, resulting in growth inhibition in the later stage

But this patent has the following defects: glycine products cannot remove inorganic anions brought in raw materials such as SO4 2- 、CI - etc., the product purity is poor, which affects the palatability of the feed, and also causes the metabolism of Na+ ions in the animal body to be vigorous, resulting in a low deviation of the electrolyte balance (dEB) in the animal body, and low biological potency of inorganic trace elements, requiring a large amount of addition
