example 1

[0070] Get 6 100 ml capacity beakers, wash them, dry them and divide them into two groups, each group has 3 beakers, and take 20 ml of hydrochloric acid solution filled with pH 4.0 in each beaker. The three cups of one group respectively measure the unshielded microelement nutrient source premix prepared according to the above-mentioned three (1) formula, and the measured amount is calculated as 150 mg based on copper, and is marked as the control group. The three cups in the other group measured the microelement nutrient source premix completely prepared by the patented technology respectively, and the measured amount was also calculated as 150 mg based on copper, and was marked as the experimental group. Finally put into a water bath at 37 degrees Celsius for 2 hours. Then take samples and analyze the ratio of ionic state trace elements to total trace element compounds, the results are as follows:

[0071] control group test group iron(%) 88.5±2.75 44....

example 2

[0074] With 4 DLY weaned piglets weighing 8±1.01 kg, 30 minutes after eating, anesthetize and open the bottom of the stomach to collect gastric digestive juice, and collect 40 ml of each pig for later use. Then take 6 beakers with a capacity of 100 ml, wash and dry them and divide them into two groups, with 3 beakers in each group, and fill each beaker with 20 ml of collected gastric digestive juice. The three cups of one group respectively measure the unshielded microelement nutrient source premix prepared according to the above-mentioned three (1) formula, and the measured amount is calculated as 150 mg based on copper, and is marked as the control group. The three cups in the other group measured the microelement nutrient source premix completely prepared by the patented technology respectively, and the measured amount was also calculated as 150 mg based on copper, and was marked as the experimental group.

Abstract

The invention discloses a trace element and nutrient source premix and belongs to the field of a forage premix and its preparation method. The premix comprises a trace element nutrient source nucleus material as well as a composite screener. The composite screener formula is composed of potato starch, ethyl cellulose, anhydrous ethanol and magnesium stearate. The invention also discloses a preparation method of the above premix, comprising several steps of pre-preparation, nucleus material pre-shielding, nucleus material re-shielding and shielded product drying. According to the technology and method provided by the invention, trace elements in stomach and small intestine environments of monogastric animals, especially pigling release trace element ions according to nutritional and physical needs so as to minimize nutrient waste; and the trace elements can be fully utilized by microflora in the rear portion of alimentary canal so as to stabilize and balance the micro-ecological environment. By the utilization of the product prepared by the technology and the method provided by the invention, ionization degree can be reduced by more than 30%.

Description

technical field [0001] The invention belongs to the field of a feed premix and a preparation method thereof, and in particular relates to a trace element nutrient source premix. Background technique [0002] Trace elements are an important part of animal nutrition and a core component in the production of feed premixes. The commonly used trace element nutrient sources are generally inorganic salts or oxides. Their strong pro-oxidation effect seriously affects the storage life and nutritional quality of feed compound premixes and compound feeds, especially seriously reducing vitamins and fat nutrients. The nutritional effectiveness of the feed has always been a long-standing and difficult problem that the feed industry and aquaculture production are very worried about. [0003] The research on animal nutrition and physiology also proves that trace element sources, especially high-zinc and high-copper trace element sources, have a high degree of dissociation under the gastric...
