Prevention and treatment of mastitis in dairy cows in 1.

In the process of dairy farming, mastitis disease is the most common. In general, clinical mastitis often leads to a rapid decline in milk production, and the milk produced by the affected cow during this period is inedible. Once there is invisible mastitis, not only the milk production and milk quality of cows will decline sharply, but also the diseased cows may even gradually be unable to lactate. According to relevant statistics, the proportion of dairy industry losses caused by mastitis is extremely high, so it is listed as a key control object.

The survey shows that the emergence of mastitis in dairy cows is often caused by bacterial infection, so the prevention and management in this area is very important.

First of all, the cow body, cattle house cleaning must be put in place to ensure that the breeding area timely ventilation, often replace the mat and manure timely cleaning, etc;

Secondly, in daily milking work, both machine milking and manual milking must do a good job of breast scrubbing and cleaning, and the cleaning and maintenance of equipment must be put in place simultaneously;

Finally, the allocation of diets must ensure balanced nutrition and feeding standards, and try to avoid breast scratches caused by cattle fighting, and timely isolation of diseased cattle suffering from mastitis to avoid further deterioration or infection.

At present, many cattle farms give cows a medicated bath and regularly soak the nipples of cows for 10 to 30 seconds each time, which can effectively prevent bacteria from entering the milk tube.

1. Inoculation of mastitis vaccine mastitis vaccine is a kind of special vaccine to prevent mastitis, can effectively prevent mastitis, especially the occurrence of recessive mastitis. The specific method used is as follows: subcutaneous injection of 5 ml at the shoulder for 3 times, injection of 1 needle at the time of dry cow milk for the first time, injection of the second needle after 30 days, and injection of the third needle within 72 hours after delivery. Can effectively prevent the occurrence of mastitis. 2. Nipple medicated bath starts 10 days before stopping milk or going into labor, 1-2 times a day, and once after each milking of lactating cows. The main medicated bath drugs are 4% sodium aminate, 0.30-0.50 chlorhexidine, 0.20 peroxyacetic acid and 0.50-1% iodophor, etc. 3. Treatment in the traditional antibiotic therapy combined with traditional Chinese medicine therapy, the effect is obvious. Yunmoss can be taken orally at a dose of 250-300g according to the shape of the cow, with one dose every other day and three doses as a course of treatment. Chitosan can also be taken orally, 15 grams a day, twice a day, mixed into the concentrate, after eating, add coarse material, feed for 6-8 days.

2. cowslimb and hoof diseaseThe prevention and control programme

In cows prone to several diseases, limb hoof disease is also a greater impact. It is reported that the incidence of arthropod and hoof disease is high in summer and autumn, which is easily caused by uneven nutrition of dairy cows or improper feeding environment. And when the breeders are negligent in the health care of the limbs and hooves of dairy cows, the limbs and hooves are also easy to take advantage of the deficiency. When the disease occurs, the walking of dairy cows will be greatly affected. If not treated, the deterioration of the disease will also lead to serious paralysis of the lower limbs of dairy cows, which will gradually affect the production performance of dairy cows and cause huge economic losses to farms (households).

Since the occurrence of limb and hoof diseases is often closely related to the feeding environment, environmental management should be the first step. On the one hand, the inspection of the exposed nails of the cow bed must be detailed and thorough to prevent the cattle from scratching their limbs and hooves in daily feeding. At the same time, anti-skid measures should also be taken for the laying of the cow travel passage. On the other hand, the cleaning and cleaning of the cattle farm should be carried out regularly, and the sterilization and disinfection work must be thorough. Secondly, when collecting sperm in winter, attention should be paid to the way of rein pulling cattle, and post-Rafa must be taken to prevent limb and hoof breaking injuries. Finally, in the care of the cow's limb hoof, the high incidence of the disease must be regularly repaired hoof, when necessary, the hoof should also be a certain degree of medicine bath. Breeders should regularly clean up the dirt between the legs and toes of dairy cows, and add appropriate additives to the feed at regular intervals to ensure the balanced growth of the legs and hooves.

Prevention of limb and hoof disease in dairy cows

1. Prevent regular trimming and cleaning of cattle hooves, pour 10% copper sulfate solution into a sprayer with a nozzle, and spray directly into the hoof fork once every other day.

2. Treat and fix the affected cow in the six-column column column, clean the affected hoof with 1% potassium permanganate solution, repair the bottom of the hoof, expand the rotten cavity into a reverse funnel shape, let it flow out blood, and fill the wound with potassium permanganate to stop bleeding. Then wash and dry with 3%-5% potassium permanganate, pour the ground of dragon's blood into the wound cavity after debridement, and then bake it with red-hot axe-shaped soldering iron to melt dragon's blood and combine it with cutin. If the wound cavity is deep, it is better to melt it in layers, bind and fix it with bandages, and check once every 5-7 days. If the bandage does not fall off, it does not need to be treated, otherwise, it can be repaired once, it. If there are more pus and blood secretions in the lesion, it will be closed after regular treatment, and then the lesion will be dehydrated and regenerated.

Prevention and Treatment of Infertility in 3. Dairy Cows

Cow infertility is more common in China's dairy industry, and it is relatively difficult to cure. At present, it seems that the impact of infertility on the dairy industry is huge, and its incidence is basically above 25%. In terms of disease, infertility is often dominated by bovine ovarian disease and bovine uterine disease, among which the incidence of bovine uterine disease is relatively high, which is also the focus and difficulty of prevention and treatment of cow infertility in recent years.

The prevention and treatment of cow infertility should pay attention to four aspects. First of all, when the estrus stage is about to enter, the breeder must make close observation of the estrus period, and find the estrus cow in time and determine its estrus period. Secondly, in the delivery stage of dairy cows, the implementation of maternity care can also effectively prevent the occurrence of infertility. At the same time, for most cows in labor, natural childbirth should be the first choice, and artificial midwifery must not be rushed. Finally, in terms of feeding management, feed feeding and environmental control should not be negligent. It is necessary to ensure sufficient exercise for dairy cows while ensuring the full price of feed and balanced nutrition.

4. Other

In addition to the above diseases, the common diseases of dairy cows include calf diarrhea, abomasum displacement and fetal retention. Although these diseases are more common than other diseases, their harm to dairy farming is not to be underestimated. Moreover, as the number of dairy cows continues to increase, the impact of these diseases may grow, which in turn will cause problems for work. In the current situation of rapid development, the prevention and treatment of common diseases in dairy cows is obviously inseparable from drug treatment. With the impact of various diseases on the production of dairy cows is more and more bad, the corresponding disease prevention and control vaccine also came into being. In the daily feeding management, cows are regularly vaccinated to improve the resistance of the herd. At the same time, when there is inflammation in the cattle body, in addition to making adjustments to the feeding management, the necessary drug injection and drug coordination must also be used rationally. Moreover, it is feasible and desirable to prevent and treat diseases by adding corresponding drugs to dairy cow feed, which not only ensures the nutritional balance of the body, but also reduces the work of disease prevention and control to a certain extent.
