How to observe and diagnose sheep diseases? These six methods you need to know
Inspection is the direct observation of the sheep's mental state and the various abnormal changes it presents. Healthy sheep generally compete for feed, move at the same speed, and react quickly; sick sheep often lag behind the flock, stop eating, stand still, or lie down. Posture: healthy sheep have bright, spirited eyes and move lively and steadily; when sheep are sick they often show unsteady movement or are unwilling to walk, and some infectious diseases also present special postures, such as tetanus manifesting as stiff limbs, and sheep with coenurosis (brain tapeworm cysts) or sheep nasal bot fly turning in circles, and lameness.

The seeds are very small, averaging 0.69 mm in length and 0.14 mm in width, with the embryo averaging 187 micrometers in length. When sown in early June, half a month later the embryo cells begin to differentiate, the embryo diameter increases noticeably, the middle of the seed swells, the suspensor is dark in color, and the newly differentiated cells at the apex of the embryo are light in color; then the seed coat ruptures at this end, and the embryo breaks through the seed coat. July happens to be the rainy season in the production areas, with soil temperature around 25°C and soil moisture around 60%.
