Pregnancy and fetal protection of foxes

Under normal circumstances, after mating, the female fox sperm and egg combine to form a zygote, that is, enter the pregnancy period. The average gestation period of foxes is 52 days. In the early stage of pregnancy, the embryo develops slowly and rapidly in the later stage. After 30 days, the abdominal circumference increased and the intercourse sagged slightly, which became more obvious in the later stage. During pregnancy, due to the development of the fetus, the metabolism of the female fox is exuberant, and the desire to eat not tired of essence increases sharply, the weight of the fox increases accordingly, and the coat color also appears bright. The female fox is docile, timid, sensitive to surrounding foreign bodies and abnormal sound, and is slow to move, and likes to lie down and rest and bask in the sun.

In order to ensure the normal pregnancy of the female fox, in addition to providing nutrition to outsiders according to the standard, it is necessary to ensure the quiet of the fox farm from time to time and put an end to visits and motor vehicles. Beverage personnel should take good care of them and it is strictly forbidden to run foxes. Disinfect the production box and cage 5-10 days before the due date, if possible, use flame disinfection, or disinfect with 3% fire lye at the same time, keep the incubator warm. For the weak side of high latitude, the four corners of the production box should be compacted with soft miscellaneous strokes, and the nests should be built artificially, and the gaps of the production box should be pasted with paper to prevent cold wind from invading. Low-latitude Hebei, Shandong areas due to the arrival of the litter season, the weather has become warmer, heat preservation requirements are not so strict, but there should also be bedding grass to prevent a sudden cold snap.

The female fox has 4-6 pairs of nipples, and the breast area develops rapidly from front to back in the late pregnancy. During the parturient period, due to the stimulation of high breast development, most of the female foxes can depilate their mouths by themselves, and the female foxes with good nipples and milk can be seen with milk secretion.
