Manganese deficiency in newborn calves The sick calf has obvious loss of appetite, dry and discolored hair, deformed legs, ball joints on the ground, swollen tarsal joints and twisted legs, joint paralysis, movement disorders, and difficulty in standing up. Some calves occur before birth to limb and leg bending-based rickets. There are many cattle in manganese deficiency areas who have paralysis, moo, muscle tremor and even spasmodic contraction from time to time, physical weakness, weight loss, obvious movement disorders, dry and dull hair. The weight, length and fracture resistance of the humerus were significantly reduced.
Causes of manganese deficiency in cattle
(1) Primary manganese deficiency
Due to the low manganese content in the diet. Plants growing in low manganese soil also have low manganese content, and dairy cows are prone to disease when fed with forage grown on such land for a long time.
(2) Secondary manganese deficiency
It occurs in the presence of factors that affect the absorption and utilization of manganese, such as calcium, phosphorus and phytate content in forage, which can block the absorption of manganese and reduce the utilization rate, thus inducing manganese deficiency. Suffering from chronic gastrointestinal diseases, can also hinder the absorption of manganese, utilization.

(2) Manganese deficiency in adult cows
In addition to some of the same symptoms and calves, there are sexual cycle disorders, estrus is slow or not estrus, ovarian atrophy, ovulation stagnation, not easy to conception or conception rate decreased, early occurrence of unexplained recessive abortion, weak fetus or stillbirth. Reduced milk volume, severe absence of milk.
(3) Breeding bull manganese deficiency
Testicular atrophy, poor semen quality, loss of libido, severe loss of mating power, while periarthritis, lameness, etc.
(4) Determination of manganese content in blood, milk and hair
Less than 18-19 μg/100 ml for adult cows and 20 μg/100 ml for calves. The content of manganese in milk is less than 30-40 micrograms/100 ml, and that in colostrum is less than 130 -160 micrograms/100 ml, which can be regarded as manganese deficiency. The manganese content in the coat decreased to less than 8 mg/100g for suspected manganese deficiency disease cattle.
(1) Improve feeding and supply manganese-rich green fodder.
(2) Supplementation of mineralsLick brick.
