Yellow and white dysentery of calves is an acute infectious disease of newborn calves caused by pathogenic Escherichia coli, mainly through the digestive tract infection. Spring is the peak period of calves and the peak period of yellow and white dysentery of calves. Clinically, it is characterized by enteritis sepsis, enterotoxemia or structural organ inflammation, which causes the disease and death of calves or the growth and development of calves, which is extremely harmful to the cattle industry.
According to the symptoms of the disease can be divided into sepsis, intestinal toxin blood type, enteritis type three.
1, defeat blood type.It often develops within 3 days after birth, showing an acute process, and often dies within a few hours or 1 day after the onset, with the death rate reaching more than 80%. Most of them have diarrhea, feces like protein soup, pale gray, occasionally accompanied by elevated body temperature, lack of energy and other symptoms. Calves that have been resistant to sepsis can develop arthritis, meningitis or omphalitis after 1 week.
2. Enterotoxic blood type.The acute person suddenly perishes. If the course of disease is long, typical toxic neurological symptoms can be seen, first happy, then bored, until coma, and then death.
3, enteritis type.Characterized by the onset of diarrhea symptoms. At first, the excrement is pale yellow, porridge-like and foul-smelling, followed by watery, white light gray, contaminated hindquarters and legs, and often abdominal pain. Late high dehydration, failure and lying on the ground, occasional spasms. If not treated in time, often due to collapse or secondary pneumonia and death. General cases can be self-healing, but later stunted.

Physical reasons
Affected by climate, season, temperature and environmental factors, if the litter is too thin or no litter, the temperature of the cow's udder of calves and cows lying on the light ground will decrease, and the temperature of the milk will decrease accordingly. Calves eating such milk will easily cause intestinal spasm, which is also easy to cause intestinal spasm. Similarly, if the temperature of artificial breast-feeding milk is too low, it can also cause this disease.
Feeding management reasons
Calves do not eat clean colostrum in time, drinking water is unclean, calves have the habit of licking the ground, walls and articles contaminated with bacteria, too much or too little concentrate during lactation or too much acidity of feed is also easy to cause the disease, premature intake of silage, or cold and humid pens are also easy to cause the disease.
