Problems solved by technology

[0003] In the existing production technology, potassium iodide is usually used as an iodine additive in feed, but the stability of potassium iodide is relatively poor, and the feed is affected by various environmental factors during transportation and storage, and potassium iodide is easily converted into elemental form and volatilizes.

Embodiment 1

[0027] Randomly select 40 broiler chickens as the test subjects, 20 in the test group and 20 in the control group, both groups are fed with broiler feed made by the test base of Guangdong Xilong Chemical Co., Ltd. Substance 0.1 kg. The contents of each component in the compound minerals are (g / kg) calcium hydrogen phosphate 570, sodium chloride 80, potassium citrate 250, potassium sulfate 60, magnesium sulfate 30, manganese carbonate 3, ferric ammonium citrate 5, zinc carbonate 1.5, copper carbonate 0.42, potassium iodate 0.01, sodium selenite 0.01, chromium potassium sulfate 0.06. The test lasted for 30 days, and the test results are shown in Table 1. It can be seen from Table 1 that each chicken in the test group gained 9.6g more weight per day than the control group, and the growth rate was 30.9% higher than that of the control group.

Embodiment 2

[0031] Randomly select 40 laying hens as the test object, each of the test group and the control group has 20, and both groups are fed with the laying hen feed made by Guangdong Xilong Chemical Co., Ltd. test base. Complex minerals 0.15kg. The contents of each component in the compound minerals are (g / kg) calcium hydrogen phosphate 550, sodium chloride 80, potassium citrate 260, potassium sulfate 70, magnesium sulfate 30, manganese carbonate 3, ferric ammonium citrate 5, zinc carbonate 1.5, copper carbonate 0.42, potassium iodate 0.01, sodium selenite 0.01, chromium potassium sulfate 0.06. The test lasted for 30 days, and the test results are shown in Table 2. It can be seen from the table that the content of mineral elements in the eggs of the test group is much higher than that of the eggs of the control group.

Abstract

The invention discloses a method for preparing a poultry feed additive compound mineral substance, and belongs to the technical field of poultry feed additives. The mineral substance comprises the flowing elements: calcium hydrophosphate, sodium chloride, potassium citrate, potassium sulfate, magnesium sulfate, manganese carbonate, ammonium ferric citrate, zinc carbonate, copper carbonate, potassium iodate, sodium selenite and potassium chromium sulfate. In the compound mineral substance, the potassium iodate replaces the conventionally added potassium iodide to serve as the source of iodine element, the iodine element loss caused by decomposition and volatilization of the potassium iodide is prevented, the function of keeping the iodine element for a long time can be realized, and the production, processing, sales and feeding are facilitated. The addition amount of the mineral substance in the conventional poultry feed is 1/1,000-2/1,000; and experiments show that the mineral substance can stimulate the appetite of livestock and promote growth.

Description

technical field [0001] The invention relates to a poultry feed additive, in particular to a preparation method of a poultry feed additive compound mineral, belonging to the technical field of poultry feed additives. Background technique [0002] Mineral elements are distributed in various parts of the animal body and play an important role: form bones and teeth; exist in blood, lymph or cell fluid in the form of ions, and play a role in adjusting pH and osmotic pressure; interact with proteins Combined with fat, it exists in amino acids, nucleic acids and most coenzymes, and participates in energy metabolism and enzyme activities. In feed additives, mineral elements are nutritional additives, and their role is extremely important. The amount of various elements in the poultry diet will not only affect the feed utilization rate, but also cause poultry due to the imbalance of various elements. various nutritional disorders. In the same feed produced in different regions, the...
