Trace element and boar reproductive performance

Modern studies have found that the lack of trace elements in the body of boars can lead to loss of libido in boars, reduced semen volume and quality, and affect breeding and breeding. Zinc is an essential trace element in animal organisms. It is involved in the physiological activities of various enzymes in animal organisms, and has a very important influence on the synthesis of proteins, nucleic acids, and gonads. Zinc helps to improve the body's resistance to disease, can ensure the sexual ability of boars, and treat impotence. Since the inclusion of phytic acid oxalic acid in plant-based diets impedes the absorption of zinc, the hot weather in summer can cause the appetite of boars to decline, resulting in a decrease in zinc intake. Zinc deficiency in diets can hinder the development of testicles in boars. Adding 70-80mg/kg zinc to the general diet can meet the growing needs of the pig. Manganese has important nutritional and physiological functions for animals. Manganese deficiency can cause animal bone abnormalities, claudication, posterior joint swelling. Manganese deficiency in diets reduces boar libido and sperm production. Selenium has affinity for boar testis, epididymis, prostate and seminal vesicles, and there is a significant positive correlation between selenium content and sperm density in epididymis. Selenium deficiency can cause anemia, boar semen quality decline, epithelial cells blocked and cause testicular function degradation. In selenium-deficient areas, attention should be paid to the addition of vitamins, and pay attention to the supply of vitamin E, because selenium and vitamins are closely related to the role of the body's enzymes have a synergistic effect. The main function of iodine is to participate in the composition of the thyroid gland, regulate metabolism in the body and maintain heat balance in the body, and play a regulatory role in reproduction, growth and development, erythropoiesis, and blood circulation. The typical symptom of iodine deficiency is goiter. Excessively low thyroid activity reduces boar libido, and seaweeds are rich in essential substances that iodine is protecting thyroid vitality. The lack of iron not only causes anemia, but also makes the boar mentally sleepy and powerless, which is bound to affect boar participation in breeding. Chromium helps to promote the metabolism of cholesterol and enhance the body's endurance. At the same time, under certain conditions, it can promote the production of muscle, avoid excessive fat deposition, and prevent boar obesity.

Blood System:
Blood system is also called circulatory system.
For the treatment of diseases of the circulatory system:
According to the American Heart Association, cardiovascular disease is the leading cause of death in the United States. Because of its vastness and critical nature, it is one of the systems of the body most prone to disease.

One of the most common diseases of the circulatory system is arteriosclerosis, in which the fatty deposits in the arteries causes the walls to stiffen and thicken the walls. According to the Mayo Clinic, the causes are a buildup of fat, cholesterol and other material in the artery walls. This can restrict blood flow or in severe cases stop it all together, resulting in a heart attack or stroke.

Stroke involves blockage of the blood vessels to the brain and is another major condition of the circulatory system, according to Mitchell Weinberg of the North Shore-LIJ Health System. [Risk factors include smoking, diabetes and high cholesterol," he noted.

Another circulatory disease, hypertension - commonly called high blood pressure - causes the heart to work harder and can lead to such complications as a heart attack, a stroke, or kidney failure, the NLM noted.

An aortic aneurysm occurs when the aorta is damaged and starts to bulge or eventually tear, which can cause severe internal bleeding. This weakness can be present at birth or the result of atherosclerosis, obesity, high blood pressure or a combination of these conditions, according to Weinberg.

Peripheral arterial disease (also known as PAD) typically involves areas of narrowing or blockage within an artery, according to Jay Radhakrishnan, an interventional radiologist in Houston, Texas. In addition, chronic venous insufficiency (also known as CVI) involves areas reflux (or backward flow) within the superficial veins of the lower extremities.

PAD is diagnosed with noninvasive testing including ultrasound, CT scan, and/or MRI. Ultrasound is the least expensive of these methods, but also gives the least amount of detail, as CT and MRI show a much higher degree of anatomic detail when identifying areas of narrowing/blockage within an artery. CVI is diagnosed with ultrasound as the venous reflux can be measured accurately by ultrasound, which ultimately guides treatment.
