In the course of raising cattle, the breeder can determine whether the cow is healthy from the cow's body temperature. Therefore, it is very important to use disposable temperature probe measure the temperature of cattle regularly.
It is important to note that after intense activity, sun exposure and plenty of water, the cow should rest half an hour before the measured the temperature.
A healthy cow’s temperature within a day will be a slight change, in general, higher in the morning, afternoon is low, temperature difference within a difference of 1 ℃.
It should be measured from 8 am to 9 am and 4 pm to 5 pm, and observe the difference in temperature.
Cattle normal temperature is 38.5 ℃ ~ 39.5 ℃, young cows temp is 38.0 ℃ to 39.50 ℃, adult cattle temp is 38.0 ℃ to 39.0 ℃.
Sick calf has a lower body temperature than normal, usually with a large loss of blood, a rupture of the internal organs, a toxic illness, or a death.
If the calf body temperature is higher than normal and with other febrile symptoms, it can be judged that the cow is fever.
Cattle temperature within 1 ℃ is slight fever, increase within 2 ℃ is medium heat, increase more than 2 ℃ is high heat.
There are three fever types that are significant for the diagnosis of cattle:
1. Continuous Fever
High heat for more than 3 consecutive days, and the daily temperature difference is within 1 degree. The sick calf may suffer from infectious pleural pneumonia, calf paratyphoid, etc.
2. Remittent Fever
Calf’s daily temperature difference in more than 1 ℃, and can’t fall under normal temperature, this cattle may have purulent disease, sepsis or bronchopneumonia, etc.
3. Intermittent Fever
If fever and non-febrile occur alternately, the sick cow may suffer from Chronic TB, Piroplasmosis, or Trypanosomiasis
