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.
Thrust Spherical Roller Bearing
A spherical roller thrust bearing is a rolling-element bearing of thrust type that permits rotation with low friction, and permits angular misalignment. The bearing is designed to take radial loads, and heavy axial loads in one direction.
Spherical roller thrust bearings are of separable construction, The shaft washer is assembled with the cage and a number of asymmetrical spherical rollers and has to be used along with a housing washer having sphered raceway. During mounting, the rings are to be fixed on to their respective seats – shaft washer on the shaft and housing washer on to the housing and then they have to be put together carefully They are manufactured in multiple series.
The raceway of the housing washer is at an angle with it`s ais of rotation, so as to be able to allow the rollers to remain in touch with it. As a result, a spherical roller thrust bearing is capable of carrying both a radial as well as an axial load. Spherical roller thrust bearings – because of their internal geometry – are capable of accommodating certain amount of misalignment. However, they can take axial loads only from one direction, and may need to be used in pairs in Back-to-Back or Face-to-Face arrangement, if thrust load from both the directions are to be carried.
Spherical roller thrust bearings are capable of compensating misalignment and shaft deflection.
The bearings are manufactured in normal accuracy. However, bearings with higher running accuracy can also be supplied.
