Problems solved by technology

[0003] In the existing animal feed, copper sulfate is generally used as a conventional copper source additive, but because copper sulfate is an acidic compound, it is not only easy to corrode processing and production equipment, but also has high water solubility and easy moisture absorption, which is easy to cause agglomeration; copper sulfate also It can promote oxidation reaction, accelerate the destruction of feed nutrients (such as vitamins) and oil rancidity, making the biological utilization low; it is easy to form copper molybdate complex in the rumen and excreted with feces, which is very destructive to the environment

Embodiment 1

[0018] Biological potency and feeding experiment of weaned piglets were carried out on basic copper sulfate. Select 144 healthy disease-free weaned piglets of the same breed (Du×Long×Da) and close in age at birth, and randomly divide them into a control group and three test groups, with 6 replicates in each group and 6 pigs in each replicate. Basic copper sulfate was added, copper sulfate pentahydrate was added to the control group, 250g of basic copper sulfate was added to the test group (if no special instructions, the following additions were calculated according to the addition amount per ton of full-price feed), and the test group two Add 300g, test three groups add 350g; control group add copper sulfate pentahydrate 250g. The test results are shown in Table 1 and Table 2 below:

[0027] Broiler chicken feeding experiment on basic copper sulfate. Select 600 hatched AA broilers from the same batch and randomly divide them into 4 groups (three test groups and one control group), with 3 replicates in each group and 50 broilers in each replicate (half male and half female). The test group added 250g of copper sulfate, the test group 2 added 150g of basic copper sulfate, the test group 3 added 250g of basic copper sulfate, and the control group did not add any copper source.

Abstract

The invention discloses application of basic copper sulfate as a trace element copper source additive in an animal feed. Animals which are fed by the feed comprises pigs, poultry or aquatic livestock and the like, preferred addition amount of the basic copper sulfate is 250-350g for piglets, 150-300g for finishing pigs, 20-100g for brood sows, 20-250g for the poultry, and 20-100g for the aquatic livestock, which are added to each ton of a complete feed. The basic copper sulfate is taken as a novel copper source additive in the animal feed, and has the advantages of simple production process, lower cost, stable product quality, low addition level, small dosage, good palatability, high biological value and the like.

Description

technical field [0001] The invention relates to the application of a basic sulfate in animal feed, in particular to the application of a basic sulfate in animal feed as a trace element additive. Background technique [0002] Basic copper sulfate, also known as copper tribasic acid, is a good protective broad-spectrum fungicide in the prior art, and is suitable for all diseases that can be prevented and controlled by Bordeaux mixture, mainly including pear scab, anthracnose, Apple anthracnose, ring spot, citrus canker, resinous disease, grape downy mildew, black rot, banana leaf spot, cucumber downy mildew, bacterial angular spot, tomato (potato, eggplant, pepper) blight and Rice smut, etc. Existing basic copper sulfate preparations include wettable powders containing 80% (mass fraction) basic copper sulfate, and also suspending agents containing 30% or 35% (mass fraction) basic copper sulfate. [0003] In the existing animal feed, copper sulfate is generally used as a conv...
