More closing pressure - and then you tell them again - not this time, and a bit later - for the 3rd time - not this time, and hey - I have graciously stayed past the hour and a half and now we have to get to......................... Adios Amigos.
The normal temperature of an adult cow is around 38.5Â°C (approx 101.5Â°F. A temperature over 39.5Â°C (103Â°F) may indicate an infectious or inflammatory process.
After the first heat, about 25 to 30% of cows have a short cycle. A normal cycle lasts 19 to 23 days in beef cattle. However, short cycles last only 12 to 15 days. During short cycles progesterone, the hormone that supports pregnancy, does not stay elevated for enough days to allow implantation to occur. In 70 to 80% of beef cows, there is a brief (2 to 8 day) increase in progesterone that occurs before the first heat (Figure 1).
