The last weeks of pregnancy and the first weeks of lactation are a critical period, especially in high-yielding cows. During this time, the body’s need for nutrients increases rapidly, which can lead to the occurrence of serious diseases.
The perinatal period includes the last 3 weeks of drying off and the first 3-4 weeks of lactation. From a physiological point of view, cows undergo intense changes during this time (preparation of the mammary gland for the lactation period, doubling of the fetal body weight, increased demand for nutrients), which may contribute to lowering the immune status of the body. The diseases observed in the perinatal period can basically be divided into two groups.
The first are caused by vitamin and mineral deficiencies, while the second are caused by an incorrect energy balance with protein. The most frequently observed disorders of the first group include hypocalcemia and deposition, the symptoms of which may occur not only in the first 12-72. hours after calving, but also several days before the termination of pregnancy. In the case of hypocalcemia, there are three stages. In the first, the cow takes a standing position but walks shakily when moving. In the second stage, there is a problem with standing up, and in the third, flaccid paralysis is observed, which is manifested by the grated ability to support the weight of the head and the sternum position (lying flat). According to many scientists, the symptoms described above are the result of a disturbance in the body’s calcium-phosphate balance. In addition to the high intake of calcium (Ca), the main cause is an excess of sodium (Na) and potassium (K) in the daily ration during the dry period. This condition leads to an increase in the concentration of cations that raise the blood pH value. The alkaline pH of the body fluid reduces the secretion of parathyroid hormone, and thus blocks the function of protein receptors on the bone surface. In this situation, the Ca mobilization mechanism from the bone is blocked, and the reservoir circulating in the blood is quickly used for colostrum production. The birthing action is not without significance, as large amounts of Ca are spent on the contraction of smooth muscles (labor pressure).
The main diseases resulting from an incorrect balance of the basic components of the ration are milk fever, ketosis and acidosis.
Theoretically, it is assumed that a well-balanced dietary dose supplements nutrient deficiencies and protects against perinatal disorders. Unfortunately, the increase in the concentration of estrogens, both before and after giving birth, causes the cow to consume less fodder than it requires, especially in the first 2-3 days after calving. During this period, a significant amount of colostrum is also produced, which is characterized by a high content of nutrients, minerals and vitamins. In order to prevent hypocalcemia, retention and retention of the placenta, good results are achieved by adjusting the preparations in the form of post-calving. One of them is Maxdrink. The special composition of the ingredients of the preparation accelerates the regeneration of the body, and, importantly, supports the activation of metabolic functions. In addition, the high content of minerals and easily digestible calcium quickly restores the electrolyte balance, and the presence of vitamins improves the immune system and prevents placental arrest and mastitis. An additional advantage of this company’s postpartum formula is the presence of yeast, which stimulates the appetite, stabilizes the composition of the rumen microflora and the pre-gastric motility. The taste is also an important criterion. The recipe of Maxdrink has been adapted to the taste preferences of cows, thanks to which the preparation is readily taken. Importantly, the use of it in the early period after calving allows for effective rumen filling, and thus protects the cow against a dangerous metabolic disorder – abomasum displacement.
