Complex additive for boars and preparation method and using method thereof

Abstract

The invention relates to a complex additive for boars and a preparation method and a using method thereof. The additive is prepared from the following components in percentage by weight: 1.00 to 5.00 percent of N-carbamylglutamic acid, 1.00 to 5.00 percent of vitamin E, 0.10 to 0.30 percent of vitamin B2, 0.10 to 0.30 percent of vitamin C, 1.00 to 2.00 percent of organic zinc, 0.03 to 0.50 percent of organic chromium, 0.04 to 0.60 percent of organic selenium, 0.04 to 0.50 percent of carnitine 50, 0.001 to 80.00 percent of functional protein, 0.03 to 0.50 percent of antioxidant, 0.001 to 0.40 percent of anti-mildew agent and the balance of carrier. The preparation method comprises the following steps of: 1) weighing the N-carbamylglutamic acid, the vitamins, organic trace elements, the functional protein, the antioxidant, the anti-mildew agent and the carrier according to a proportion in percentage by weight respectively; and 2) fully mixing the raw materials weighed in the step 1) in a mixer uniformly to obtain the product. The using method comprises that the complex additive is added into daily ration of the boars, wherein the adding amount is 200 to 400 grams very day. The additive can promote the synthesis of source arginine in the bodies of animals and further enhance the synthesis of carbon monoxide (NO) and polyamine.

Description

technical field [0001] The invention relates to an additive, in particular to a compound additive for boars and a method for preparing and using the same. Background technique [0002] In the pig production system, the ratio of sows to boars in advanced pig farms using artificial insemination technology is usually controlled above 80:1. Due to the small number and difficult control, the nutritional needs of breeding boars have not attracted enough attention, and there are relatively few corresponding experimental studies. The nutritional supply of breeding boars has always been in a subordinate position in pig production. The reproductive performance of boars directly affects the quantity, quality and production efficiency of offspring. The nutritional imbalance is the main factor causing the low reproductive performance of boars. Excellent semen is an important index to measure the reproductive performance of breeding boars. However, only by meeting the necessary special...

Problems solved by technology

However, arginine is unstable in nature and is prone to change during storage. Even if the property is stable, it will have a significant effect when the addition amount reaches 1%, so the addition cost is too high

Arginine dipeptide has better stability and can release NO, but the cost of addition is also too high

In addition, arginine will antagonize lysine and tryptophan when added to the diet and absorbed by animals, affecting the utilization of these essential amino acids

All of these limit the application of arginine-based NO sources in boar feed
