Dairy cow parasites are one of the most important diseases that affect the health of dairy cows. Infected parasites can cause cows to lose production performance. The deterioration of the disease can lead to the death of cattle, and even bring a high degree of contact with infectious diseases to the entire herd. It can be given to dairy farms. It causes serious damage or even devastating blows, but its symptoms are not obvious and the resulting damage is not easily noticeable. It is easily overlooked by dairy cattle farmers. Therefore, cow deworming is one of the important tasks in disease prevention in dairy cow health systems. Dairy farm veterinarians must Strengthen dairy cows' awareness of deworming and health care, ensure the health of dairy cows, promote the growth and development of back-up cows, prevent the occurrence of cow diseases, and improve the economic benefits of breeding. Dairy cows' parasitic diseases At present, parasites that cause serious damage to dairy cows mainly include helminths (nematodes, aphids, trematodes), arthropods, ectoparasites (cockroaches, itch ticks, cockroaches, leather fly flies, cockroaches, etc.), among which gastrointestinal nematodes, cockroaches The most serious harms are caused by fleas, cockroaches, and cockroaches, causing huge economic losses to farmers, and most parasites can have serious adverse effects on the body after infection. Absorb nutrition Many intestinal parasites can directly absorb the nutrition of dairy cows, cause anaemia, block development, and also secrete digestive enzymes on the tissues, denature and dissolve the tissues into parasite nutrient fluids, thus indirectly competing with the body for nutrition, and reducing the feed conversion rate. Secretion of toxins During the growth and development of dairy cows, parasites continuously excrete metabolites and toxins, which can cause varying degrees of damage to the body. The effects or damage caused by parasites in tissues and blood is even more pronounced. mechanical injury A large number of maggots or worms parasitize and cause intestinal obstruction, which can cause severe rupture of the bowel. Intestinal parasites can cause mucosal damage when attached to the intestinal wall with suction cups. In addition, the migration of worms can also cause mechanical damage to the organs of dairy cows, causing inflammation or damage to the tissues of organs, interference with life activities, and even death. The spread of disease Parasites can cause damage to the skin or mucous membranes of dairy cows. This opens the door for other pathogens to enter the cow's body and can cause complications. At the same time, some of the parasites themselves are the carriers of certain infectious diseases and can cause cows to infect infectious diseases. Group health poses a great threat. In addition, human and livestock parasitic diseases also directly threaten human health, such as cryptosporidiosis. Clinical symptoms of cow parasites In the large-scale and intensive production of dairy farms in China, yak pre- and post-weaning are most susceptible. Parasitic diseases can cause calf malnutrition, stagnation and even death. Its clinical manifestations are neurological symptoms, sputum, and nodules in the body. There are nodules in the subcutaneous joints of the shoulders, ribs, and hind limbs. There are blemishes on the surface of the skin, scabs, and pimple, pimple, etc. Followed by lactating dairy cows, can cause decreased milk production, low milk fat, short peak milk production, miscarriage, infertility and so on. For bred dairy cows, the symptoms are loss of appetite, slow growth, weight loss, long hair, hair shaft, sharpening, hair loss, weight loss, diarrhea, bloody stools, melena, and anemia, which seriously affect growth and development. Cow deworming health program The entire group of insecticides in spring and autumn each year, for poor breeding environments (households), each year in May to June to increase insecticide once. Each field (household) can determine the best deworming program according to the local parasitic infection and epidemic characteristics, and according to the program long-term control; drugs recommended for the use of dairy cow deworming drug Ai Puli, subcutaneous injection of 1 ml per 50 kg body weight. Yak must be protected and dewormed before and after weaning to prevent nutrient stress after weaning and induce parasite infestation. Bulls must be dewormed four times a year to ensure good health. Cows must be dewormed before entering the perinatal to ensure that cows and calves are protected from parasites. Breeding cows should be dewormed prior to breeding to increase conception rates. After entering the field, new cows must be dewormed and quarantined 15 days later. Deworming must be carried out before transition or transfer, reducing pollution to new premises (fields). Dairy Cow Parasitic Disease Control Measures For prevention and control of parasitic diseases in dairy cows, we must adhere to the principle of prevention, prevention and control, and elimination of various pathogenic factors. Specific prevention and control measures are divided into the following points: Implement scientific breeding, strengthen management, maintain drinking water, feed facilities and surrounding environment, and control the way of infection. Planned, purposeful, and organized deworming, regular testing, regular inspection, and treatment one by one. The selection of anthelmintic drugs should be based on the principle of high efficiency, broad spectrum, low toxicity, greenness, no residue, no side effects, and ease of use. Elimination of intermediate hosts and vectors, opening up new channels and applying pesticides to destroy intermediate hosts based on local conditions such as chemical agents, biological agents, and irrigation and water conservancy construction. Do a good job in environmental sanitation, regularly disinfect the sheds, excrement, litter, etc., for stacking fermentation or harmless treatment. Improve the professional quality of veterinary personnel, strengthen the awareness of deworming and health care, and ensure the smooth development of prevention and treatment of parasitic diseases. discuss The establishment of a reasonable regular deworming system can effectively prevent and treat dairy cows from parasitic diseases, indirectly improve the feed conversion rate, promote the growth of reserve dairy cows, increase the resistance to diseases, and increase the immune response level of cows to vaccines while avoiding parasites. Secondary infection caused by migration in dairy cows. Improper deworming procedures and drug selection can cause significant hidden losses. The traditional levamisole, albendazole, avermectin and other drugs have the disadvantages of drug resistance, narrow insect repellent spectrum, long abandonment period, and large toxicity, and can no longer meet the actual needs of dairy farms, and thus can be prevented and The treatment, broad-spectrum, safety, long-term, non-toxic and non-residual anthelmintics have become the new direction of research and development. At present, the most used in the market is the Apily, an anthelmintic drug for dairy cows, which generally reflects better results. It is a national The only anthelmintic drug approved for safe use during lactation of cows, with safety, no residue, no milking period, wide insect-resistance spectrum, one-time use can drive both internal and external parasites, one injection lasts for 42 days, etc. Features. The domestic dairy industry urgently needs to raise awareness of insecticides and health care, strengthen basic feeding management, strengthen the emphasis on preventive drug use, improve cattle quality, increase resistance, reduce the incidence of cows, reduce treatment costs, and increase the economic benefits of breeding.
