After the cows are delivered, great changes have taken place in the endocrine, nutrient metabolism and physiological conditions. Newly-produced cows are susceptible to disease and do a good job in health care to realize their potential. The purpose of health care for newly-produced dairy cows is to reduce post-partum disease elimination, improve health, and rapidly increase milk production. The common diseases of newly-produced cows are metritis, ketosis, gastrointestinal malaise, and mastitis. They can monitor the health status through body temperature detection, rectal examination, head observation, rumen auscultation, and breasts, and perform postpartum analgesia and postpartum treatment. Rehydration, postpartum management, and ketosis testing and other nursing work.
First, the new post-natal inspection methods for dairy cows
1. Breast filling check. Before the milking in the early morning shift, check the udder filling level of the new cows and press the breasts. The tight and full breasts are healthy. If the breasts are soft and not filling, mark and record on the hind legs, and further in the barn. Check it out. The change in milk production is also one of the measures for judging the health of dairy cows. When the milk production volume drops drastically, the cows may experience a drop in feed intake. Attention should be paid to doing a thorough inspection to find out the reasons.
2. Head observation. Standing in front of the cows, observe the cow's head to understand the health of the cows. When the cow's vision is bleak, unresponsive, or subsidence of edema, etc.; nose lens dry and anhydrous beads, unclean nose, runny nose; ears sagging powerless, ear-lowering ears, cold ears and so on. This is a manifestation of the poor spirit of dairy cows. Most of them are sick cows. Attention should be paid to observation and further diagnosis. Eating appetite is one of the most intuitive ways of judging the health status of dairy cows. Dairy cows rely on flexible tongues to feed on the grass, roll the grass in the mouth, and then hurry to chew and swallow into the stomach. If cows are reluctant to feed on fodder in the trough, or if their appetite is weak, they may be uncomfortable or sick. Further observation and diagnosis are required.
3. Body temperature measurement. Abnormal body temperature is an important clinical feature of dairy cow inflammatory diseases. In the new production monitoring, the body temperature of the cows is measured every morning and evening in the middle 10 days after delivery. When cows are exposed to high temperatures, there may be infections and inflammations, and more attention should be paid to the diagnosis.
4. Auscultation. Cows were auscultated and mainly examined rumen motility and true gastric transposition. When the rumen is auscultated, on the left abdominal wall of the cows, press the earpieces firmly to make them close to the abdominal wall. Healthy cows can hear ruminal peristaltic sounds. When the stomach is auscultated, the eighth to eleventh rib area is auscultated near the left shoulder joint line, and percussive around the stethoscope, a high-profile steel tone can be heard, which may be a true gastric shift.
5. Rectal examination. Rectal examination mainly diagnoses rumen filling, fecal conditions, and uterus. First, pass through the rectum wall of the cow by hand. On the left side, you can touch the rumen and feel its filling level. Filling can be used to judge its feeding and digestion. Second, the feces is removed and the viscidity, quantity, and color are observed to diagnose the health of the digestive system of the cattle. Finally, the uterus is touched to observe the secretion of the uterus of the cow, the color, whether there is odor, and whether the cow can be diagnosed with uterus.
6. Body condition observation. By observing the muscles and subcutaneous fat of the cow, the score of its body condition can be determined. When new cattle are thin, they may be caused by various chronic wasting diseases or insufficient feed intake. If you lose weight quickly in the short term and are more likely to have ketosis, you should pay more attention to it and make a good diagnosis and record.
Second, the new dairy cows nursing methods
1. Postpartum analgesia. Cows have to bear great pain during the delivery process, and often have bowbacks, culprits, tails, and muscle tremors in the hindquarters, which reduce food intake and reduce milk production. Postpartum analgesic care is required after delivery of dairy cows, often using Meidajia subcutaneous injection of 15 milliliters, can play analgesic, antipyretic, anti-inflammatory and neutralizing the effect of body toxicity.
2. Postpartum rehydration. After the cows give birth, dehydration and loss of nutrients often occur. After the cows deliver their food, about 40 liters of them will be fed in a timely manner. Potassium chloride, calcium propionate, sodium chloride, yeasts, water, etc. will be prepared with a certain proportion of nutrient solution, which can serve as a warm belly, hunger, and increase. The role of abdominal pressure is conducive to the recovery of the cow's strength and prevention of true gastric shift.
3. Post-natal management. After the cows have given birth, they should concentrate on a single-row cowshed, and the density should not exceed 80%. Frequently, the placenta of the placenta and the cow's secretions have become the most easily breeding ground for various bacteria. The cleanliness and cleanliness of the cows directly affects the health of new cattle. It is especially important to clean up the pollutants in time and do a good job of cleaning and disinfection.
4. Detection of ketosis. After the cows are born, due to poor appetite intake, milk production gradually increases, which is a process of negative energy balance. Dairy cows are particularly noticeable after 1 to 2 weeks postpartum, which is a high incidence of ketosis. The ketone body content in the blood is a reliable and specific indicator for the detection of ketosis. Ketopathies should be tested on a regular basis every Friday in order to promptly detect ketosis. In the treatment of ketosis, the cause should be eliminated, supplemented with glucose and ketone, and symptomatic treatment. A small number of repeated repeated intravenous glucose injections for ketosis in cattle to maintain blood glucose stability. In the course of large doses of glucose, intramuscular injection of vitamin B1 and vitamin B12 can increase the hepatic glycogen reserves and maintain a constant blood glucose level, reducing the breakdown of fat.
