Copper is one of the trace elements necessary for chickens. Copper is mainly distributed in the liver, brain, kidney, heart, eyes and feathers. Copper is a component of various enzymes and activators, such as iron oxidase and tyrosinase. Therefore, copper has many functions. Red blood cell formation, bone formation, feather pigmentation, and brain cell quality require copper. Participation.
Copper is abundant in various feeds, especially in leguminous grasses, soybean cakes, gramineous seeds and their by-products, especially in fishmeal and bean cake. 4 mg of copper per kg of feed can meet the needs of the chicken. Therefore, the content of copper in the general feed can meet the needs of the chicken. However, the content of copper in plant feed is related to the concentration of copper in the soil. The plant-based feed grown in low-copper soil contains very low copper content. If no supplement is added, copper deficiency may occur.
The additive for copper supplementation in feed is generally copper sulfate. Compared with copper carbonate and copper oxide, copper sulfate has the highest biological potency. However, when there is too much zinc, molybdenum and inorganic sulfate in the feed, it will affect the absorption of copper by the chicken, which may lead to copper deficiency.
The role of copper in chicken body
1. Copper is also closely related to maintaining the nerve function of the chicken, promoting bone development and feather pigmentation. When the chicken is deficient in copper, it can cause snoring, heart failure, and fading of colored feathers.
2. Copper is a component and activator of certain enzymes, which plays an important role in maintaining the vascular elasticity of chickens. When copper is deficient, it may cause rupture of chicken arteries.
3. The role of copper in chickens is very broad. Although copper itself is not a component of chicken hemoglobin, it promotes iron into the blood to synthesize heme, and copper is a component of red blood cells and promotes the maturation of red blood cells. Therefore, when copper is deficient in copper, it affects the absorption of iron, and the red blood cells Formation and maturation are limited, resulting in anemia in chickens.
The phenomenon of copper deficiency in chicken body
When the chicken is deficient in copper, it shows anemia, abnormal bone development, deformity, and poor pigmentation of feather pigmentation in colored chicken breeds. When the laying hens are deficient in copper, the egg production is reduced, the egg weight is reduced, and thin shell chickens, shellless eggs, malformed eggs and sable eggs are produced. The eggs often die during the hatching process.
Chicken deficiency copper supplement
When the chickens were found to be deficient in copper, add copper sulfate to the feed at a dose of 90 grams per ton of feed, stir well and use for l-2 weeks. Chickens are more tolerant to copper. When the copper content in the feed exceeds 350 mg/kg, poisoning will occur, which is characterized by muscle erosion and subpetal hemorrhage. However, copper poisoning does not occur under normal conditions.
Scientific Research Special Cyclodextrin Reagent mainly including Oligo Beta Cyclodextrin, Mono-6-Azido-6-Deoxy Beta Cyclodextrin, Mono Hexamethylenediamine Beta Cyclodextrin, Mono-6-Ethanediamine-6-Deoxy Beta Cyclodextrin, Mono-6-p-Toluenesulfonyl Beta Cyclodextrin, Polyethylene Polyamine Modified Beta Cyclodextri,mono azido beta cyclodextrin cas 98169-85-8,Oligo Beta Cyclodextrin cas 98169-85-8.
Oligo (lactic acid) -beta-cyclodextrin (OLA-B-CD) is a new cyclodextrin derivative. Oligo-(lactic acid) group that can be degraded in the human body modified cyclodextrin with the general characteristics of common cyclodextrin derivatives, also has unique properties: 1, excellent biocompatibility. 2, excellent controlled release of specific guest molecular. 3, adjustable water-solubility. 4, capability to form duel interactions with specific drugs .
OLA-Î²-CD can be used to improve the solubility of water insoluble drugs, enhance drug stability and bioavailability, and achieve controlled release system or delayed release system of drugs. OLA-Î²-CD is of immense value in the field of drug development.
Features and use of Mono-6-Ethanediamine-6-Deoxy Beta Cyclodextrin:
Organic amine groups in a neutral or acid conditions can be positively charged which have very good composite ability to guest molecules.
Diamine group can form complex with many metal ions , such as Cu2+,Cr3+,Mg2+ and so on. This provide new approachs to achieve artifical enzyme and highlight supramolecular researches.
Diamine also provide a secondary amine group and a primary amine group which can be linked to many functional group. This make diamine cyclodextrin an important intermediate for cyclodextrin synthsis.
