1. The role of cobalt chloride in pig breeding

Cobalt chloride is a trace element that plays an important role in the growth and development of piglets. It promotes the synthesis of vitamin B12 in piglets, which is important for the development and growth of piglets. Piglets need a lot of vitamin B12 during the growing season, and if it is deficient, it can lead to problems such as slow growth, loss of appetite, and decreased immunity.

Second, the correct use of cobalt chloride method

Proper use of cobalt chloride can help piglets grow faster, but it requires the right amount and how to use it.

1. Cobalt chloride can be added to the feed, preferably to the newborn milk of piglets. However, it is necessary to master the appropriate dosage, which should generally not exceed 0.5mg per kilogram of feed.

2. When feeding piglets, you should master the appropriate feeding amount and feeding frequency, not too much and not too little.

3. Before adding cobalt chloride, it is necessary to know how much cobalt chloride is already contained in the feed and how much is needed for the growth and development of piglets.

4. It is best to mix the feed well before feeding to ensure that the cobalt chloride can be adequately distributed throughout the feed.

5. In the process of using cobalt chloride, attention should be paid to the growth of piglets, and if there is an abnormal situation, adjust the dosage or stop using it in time.

3. Precautions

In the process of using cobalt chloride, the following issues need to be noted:

1. Do not use cobalt chloride in excessive amounts, otherwise it may cause piglet poisoning and severe symptoms.

2. Choose regular cobalt chloride products to ensure quality and safety.

3. Cobalt chloride is a trace element, can not replace other nutrients, in the feed formula to take into account the overall nutritional balance.

4. During the feeding process, it is necessary to control the amount and frequency of feeding, and not too much or too little piglets.

【Conclusion】 The role of cobalt chloride in pig breeding is to promote the synthesis of vitamin B12 in piglets, which is important for the growth and development of piglets and helps piglets grow faster. However, it is necessary to master the appropriate dosage and use method, and at the same time pay attention to the growth of piglets to avoid abnormal symptoms.

Cobalt is a trace element, the normal content in the sheep is not more than 20,000 parts, but it plays a very important role in maintaining the normal growth and health of the body. Long-term supplementation of sheep with cobalt chloride not only reduces death, but also makes them grow faster.

pathogen

The main reason is that the cobalt content in the soil is too small, so the amount of cobalt in the feed that the sheep eat cannot meet the needs.

According to research, all higher animals need vitamin B12. Under normal circumstances, cobalt is required for the growth and reproduction of microorganisms in the stomach of sheep, and the cobalt is used to synthesize vitamin B12. Vitamin B12 is an essential vitamin not only for ruminants, but also for rumen microorganisms. However, when there is a lack of cobalt in the pasture, the synthesis of vitamin B12 is insufficient, which directly affects the growth and reproduction of rumen microorganisms, thereby affecting the digestion of cellulose. Vitamin B12 is a coenzyme of methylmalonyl-CoA mutase, therefore, when cobalt is deficient, it can cause energy metabolism disorders in ruminants, making animals emaciated and weak. Cobalt also accelerates the activity of iron in the body and promotes hematopoietic function. It can be seen that grazing sheep on cobalt-deficient grassland is susceptible to cobalt deficiency.

Since the discovery that cobalt deficiency is related to the amount of cobalt ingested, many factors have been found to affect the appearance of the disease. For example, in spring and summer, when the amount of cobalt in pasture land decreases, the disease is more likely to occur. When the cobalt content in grassland decreases year by year, the disease also increases year by year. Due to the differences in cobalt content in different plant species, the incidence of sheep grazing on different grasslands varies.

symptoms

It is characterized by progressive emaciation and weakness, followed by anemia and whitish conjunctiva and mucosa of the mouth and nose. Diarrhoea often occurs, watery discharge from the eyes, and hair growth is also affected.

The performance of lambs is worse than that of adult sheep. But as long as cobalt deficiency reaches several months, sheep of any age will die. If the sick sheep is transferred to a normal area of cobalt, it can be cured quickly, and if it returns to the affected area, it will re-emerge.

diagnosis

When cobalt deficiency is suspected, cobalt treatment is tried to see if there is a good response. The most important thing is to get a definite diagnosis first. However, the difficulty is that the symptoms of this disease are the same as those of many diseases, and there are no characteristic changes in the autopsy, so it is often confusing in diagnosis. In order to obtain a correct diagnosis, the cobalt content of soil and pasture is analyzed, and the cobalt content of soil is less than 3 mg/kg, and the cobalt content of forage grass is less than 0.07 mg/kg, which can be considered cobalt deficiency. It is also important to distinguish it from wasting caused by parasites, copper, selenium, and other nutrient deficiencies.

treat

1. When the disease is not very serious, if it can be moved to other areas, it can often recover quickly.

2. Before the rumen is mature, lambs can be injected with vitamin B12 intramuscularly, 100 mg ~ 300 mg each time.

3. Oral cobalt chloride or cobalt sulfate, the usage is 1 mg of cobalt per sheep per day, for 7 days, and repeated after an interval of two weeks, or twice a week, 2 mg each time, or once a week, 7 mg of cobalt each time. It can also be used once a month for 300 mg each time, which not only reduces death, but also makes the animal grow faster.
