“Crypto” is a small protozoan parasite which sticks to the cells that line the small intestine and damage the absorptive surface 😁 They can cause scour alone or are commonly found in mixed infections 😉 The infection usually occurs in calves between 1 and 3 weeks. Good hygiene is important as crypto can be transmitted to humans and other animals. Affected calves can become tired and weak. They may also experience loose, watery stool, which could be contaminated with mucus, blood or undigested dairy products. It is possible to also train the calves not to vomit. The only treatment is to hydrate and use Halocur. Secondary however infections must be treated It is important to provide support care. [1]
The main cause of scour in calves is less than 2. Weeks of age is a parasite called The Cryptosporidium Parvum. It can cause severe scour or abdominal pain. A licensed product can be used to prevent cryptosporidiosis-related diarrhoea. It must be used orally beginning at 2 days old for a period of 7 days. The product must be administered after calves have been fed. It should be given to any calves born following a diagnosis. Calf health can be maintained with other supportive treatments, including proper nutrition, warmth, and the exclusion of all draughts. Credit to Shaquanta Sands, for these suggestions. [2]
The analysts at extension.umn.eduThe prevention of calf scours begins even before the baby is born. A healthy cow will produce a healthy baby. The cow should have a good body condition, good nutrition, and live in a dry, clean environment. This can help to influence their health. You can use vaccines as well to alter the amount of antibodies that a cow’s colostrum (first-milk) contains. These are then transmitted to the calf. We can increase the quality and kill specific pathogens by vaccinating the cow while she is still pregnant. Discuss the options with your vet to create a vaccination protocol.

Based on an article by daleheadvetgroup.co.ukTreatment involves rehydrating and replenishing electrolytes using solutions like Life Aid Extra. Secondary bacterial infections can be treated with antibiotics. A bucket-fed calf should start scouring as soon as possible. It should also be removed from milk and given at least three feeds (two litres per feed) of electrolyte within a 24-hour period. Because there are not enough electrolyte options to meet the needs of the calf, and the capacity of the stomach wall to process milk becomes impaired, I recommend that the calf receive alternate milk and electrolyte feeds for day 2. Even if the milk is still being scourged. Because milk forms clots in the abmasum, I wouldn’t recommend that you feed it watered down milk. The scouring suckler calves I recommend that you leave them on the cow, but that you stomach tube 2 litres each day with electrolyte. This will limit how much milk it gets from the cow. An intravenous drip is recommended for any calf that cannot stand, or seems very dehydrated. Velicia Barrger amended this on March 21, 2020 [4]
