The main clinical characteristics of diseased cattle are intermittent fever, body thinning, edema of lower limbs, anemia, dry tail tip, ear tip, necrosis and even shedding. The old epidemic area usually undergoes a recessive […]
Foot and limb are the important supporting organs of cattle, which can support the weight of cattle. Foot and limb disease is a common disease in dairy cow production. Dairy cows are prone to foot and limb diseases, such as hoof deformity, fissure, and lameness. Once symptoms are presented, it is difficult to cure them, […]
True gastric torsion, also known as the right transposition of the true stomach, refers to the torsion of the true stomach around its longitudinal axis of 180-270 degrees, which is clockwise torsion of the true stomach (the right direction of the true stomach) between the liver and the right abdominal wall.

There are two factors of dystocia: narrow pelvic orifice and birth canal, the incomplete opening of the birth canal, weak contraction of the uterus and abdominal wall in cows; excessive fetal size, abnormal fetal position, stillbirth, fetal malformation, and twins. For captive cattle, especially pregnant cows who lack exercise, dystocia is more likely to occur. […]
1. Importance of selective feeding To maintain rumen stability, animals are fed most of the day, especially with a relatively slow intake of grass and straw. If selective feeding is required, cows must be guaranteed to have feed most of the time. In pastures, the maximum forage intake can be achieved only when the forage […]
During the perinatal period, cows are affected by the stress of childbirth, which results in a decrease of body resistance and the occurrence of diseases closely related to childbirth. The occurrence of these diseases often results in the decline of reproductive performance and milk production of dairy cows, even forced to be eliminated, causing serious […]
1. Adjusting Feed Formula and Feeding TimeIn summer, to alleviate heat stress, feed formulation can be adjusted appropriately. Firstly, the proportion of roughage and concentrate should be controlled at 1:1 to reduce the proportion of high-fiber feed which produces more heat in digestion and metabolism, and the proportion of concentrate should be increased by 10%. […]
Vaginal prolapse of dairy cows is an obstetric disease, which is caused by age, menstruation, physical weakness, poor feeding and lack of exercise, resulting in the decrease of tissue tension in the whole body. It causes excessive exertion of blame during childbirth, or fetal volume is too large and dystocia. Suddenly, it pulls the calf […]
Feeding environmentThe purpose of disinfection is to kill pathogenic microorganisms on the media, to make them harmless, to eliminate pathogenic microorganisms in livestock and poultry, and to cut off the transmission of infectious diseases. Personnel disinfection. Breeders should change their clothes in time when they enter the production area. Ultraviolet disinfection lasts for 3-5 minutes. Workwear […]
Dairy cows need a lot of calcium to maintain their lives and produce. Calcium is closely related to cow diseases. Calcium has the following main functions in dairy cows: it constitutes bone and teeth together with phosphorus; regulates nerve excitability; is related to a muscle contraction; participates in hemagglutination process and has hemostatic effect; is […]
The production of dairy cows is closely related to the environment. Cold, hot, temperature, humidity, wind and so on will have an impact on the production performance and health of dairy cows. Due to improper feeding and management in winter, it will lead to breast frostbite, limb disease, calf diarrhea, pneumonia and so on, which […]
