Problems solved by technology

Through the experiment, the proportion of dermatitis nephropathy syndrome in weaned piglets using high copper is more than 5% higher than that of low copper, suggesting that high copper may be one of the inducements of porcine dermatitis nephropathy syndrome, and can lead to the decline of pig resistance
(2) High copper will affect food safety
Long-term application of high copper will leave excessive residues in animal tissues and organs, affecting food safety
(3) High copper can interfere with the absorption of other nutrients
(4) High copper also causes serious environmental pollution

Embodiment 1

[0025] Application effect of embodiment 1 different doses of copper sulfate calcium in piglet feed

[0026] 160 52-day-old piglets from the nursery with similar body weight were divided into 11 groups, 20 in each group, as shown in Table 2. Each group added different types or doses of copper compounds to the full-price compound feed for piglets without high copper content, and then fed and drank freely. The weight gain and feed remuneration of the test pigs in each test group were counted for 28 days. The results are shown in Table 2. From Table 2, it can be seen that adding copper calcium sulfate (in terms of copper content, the same below) in the feed can increase the weight gain of the test pigs, improve the feed-to-meat ratio, and improve the production performance and additives. The amount is positively correlated, wherein 100ppm copper calcium sulfate can achieve the improvement effect of 200ppm copper sulfate on the production performance of test pigs.

Embodiment 2

[0030] Embodiment 2: the application effect of calcium copper sulfate in medium pig feed

[0031] 80 83-day-old, similar-weight Du Chang Sanyuan mixed lean meat pigs were divided into 4 groups as shown in Table 3, with 20 pigs in each group. Each group added different types or doses of copper compounds or other additives to the full-price compound feed for piglets without high copper content, and then had free access to food and water. The weight gain and feed remuneration of the test pigs in each test group were counted for 28 days. Result is shown in table 3, as can be seen from table 3, during the test, the copper sulfate calcium of 15ppm is obviously better than the copper sulfate and basic copper chloride of equal dosage to the improvement of test pig production performance, and can reach 150ppm copper sulfate the experimental effect. In addition, the production performance of the 150ppm copper calcium sulfate (based on copper content, the same below) test group is much ...

Embodiment 3

[0034] Embodiment 3: the application effect of calcium copper sulfate in broiler feed

[0035] 700 1-day-old fast big yellow feather broilers (mother seedlings) are grouped according to Table 4, 100 in every group. After each group added different types or doses of copper compounds to the full-price compound feed without high copper, the chickens had free access to food and water, and the weight gain and feed remuneration of the test chickens in each test group were counted for 21 days. The result is as shown in table 4, as can be seen from table 4, the copper calcium sulfate (in copper, the same below) of 10-40ppm all can obviously improve the daily gain of test chicken, improve feed-to-meat ratio, and affect production performance The improvement has obvious dose effect. 30ppm calcium copper sulfate can achieve 110ppm copper sulfate pentahydrate to improve the performance of test broilers.

Abstract

The invention discloses an application of copper calcium sulphate as an animal fodder additive, which belongs to the field of animal fodder additives. Through an experiment, it is found that, the copper calcium sulphate can achieve the effect of high dosage copper sulfate in promoting animal growth with a low dosage in animal breeding, and can replace the low dosage copper preparation as an animal basic nutrient copper element to be applied to the culturing of poultry, livestock or aquatic livestock. The copper calcium sulphate can serve as a novel, efficient and safe fodder additive to be applied to fodder machining industry and animal breeding industry, can achieve a same production performance by reducing about 50-70 percent of copper ions dosage, can obviously reduce application of copper in animal husbandry, reduce production cost, reduce toxic and side effects of high copper and reduce environment pollution and is a copper compound with unique advantages.

Description

Technical field: [0001] The invention belongs to the field of animal feed additives, and in particular relates to the application of copper calcium sulfate as an animal feed additive, in particular to the application of copper calcium sulfate as an animal basic nutrient in place of feed low-dose copper preparations and as an animal growth promoter in place of high-dose copper preparations. Background technique: [0002] Copper is one of the essential trace elements for animals, and it participates in activities such as hematopoiesis, metabolism, growth and reproduction, and disease resistance of animals. The nutritional requirement of copper for animals is 5-8mg / kg. High doses of copper up to 250mg / kg have a growth-promoting effect on animals, first discovered from pigs in 1955, and later also observed on growing chickens and laying hens. [0003] Copper is a heavy metal element that has a strong coagulation effect on protein. High-dose copper can be used to prevent mildew...
