Early weaners are more susceptible to becoming sick than other animals. Here are some conditions to watch out for.

Coccidiosis

Young weaners are particularly prone to a scouring condition called coccidiosis. The condition causes ill-thrift, scours and in acute cases, death.

Blood stained faeces (scours), straining and dehydration are typical signs of the disease. If calves survive the 5–6 days of the disease, they do become immune, but severely affected calves will remain poor doers. Prevention of coccidiosis through adequate hygiene, nutrition and the use of Rumensin (active ingredient monensin sodium) is always the best approach.

While Rumensin has many favourable attributes, it can be toxic if not mixed evenly. There are some other rumen modifiers on the market which will serve the same purpose (i.e. as a coccidiostat).

Dehydration

Scours can also be caused by other microorganisms and digestive upsets. It is important to provide adequate hygiene and to treat affected animals promptly. Dehydration is common and can be managed through the use of an electrolyte replacer. Treatment for non-digestive upset scours usually consists of a program of oral treatments and perhaps antibiotics.

Respiratory and pink-eye issues

Young stressed weaners may also be more susceptible to other sicknesses such as respiratory problems and pink-eye. As for scours, these should be observed closely and treated appropriately.

Vaccinations

It would be a good idea to vaccinate with the first shot of 5-in-1 at the time of weaning (if the calves have not already been vaccinated). This will provide some early protection from both pulpy kidney (potential risk going onto the grain mix), and tetanus (tends to be more prevalent in yards), as the higher risk pathogens at this stage.

Consult your veterinarian if in doubt about the prevention and treatment of health problems in early weaned calves.
