The ratio of fox feed

The digestive tract of the fox is shorter than that of the mackerel, the chewy surface of the teeth is not as well developed, and the large colon and cecum of the fox are not as well developed. the time for the food to pass through the digestive tract is only 25-30 hours for the fox, and about 40-50 hours for the fodder. Therefore, the ability of foxes to digest and absorb nutrients in feed is weaker than that of oysters. Foxes have higher requirements for animal feed and vitamins than oysters. Foxes have the most exuberant requirements for feed in summer and weaken in winter. The nutrition needed in different biological periods is different, the general breeding season is higher than the non-breeding season, the diet should be based on animal feed, mixed with some plant feed. When matching diets, we should first determine the amount of diet according to the nutritional needs of foxes in different biological periods, feeding standards and the physical condition and appetite of foxes. In general, the average daily feed of adult foxes is 600 grams, and the protein should reach 80 grams 100 grams. Animal feed should account for more than 60% of the diet, and the rest are plant feed. During the breeding season, vegetables should account for 10% to 20% of the total feed, mainly to ensure the source of vitamins.

Foxes have different physiological changes throughout the year, so there are different requirements in feed and feeding.

(1) before November, all kinds of foxes are required to maintain normal physical condition, not to be too fat or too thin, and to be fed in limited quantities.

(2) from November to January of the following year, is the preparation period for breeding of foxes, and the dietary standards should be properly prepared. During this period, the feed intake of foxes is reduced and can be fed once a day, but the quality of feed should be guaranteed and the nutritional level should be in the upper and middle grades.

(3) the breeding period for foxes is from late January to mid-March. due to sexual impulse, appetite is generally decreased, the diet should be easy to digest, palatable, and nutritious feed, it is best to feed fresh animal feed.

(4) the pregnancy period of female foxes is from late March to the end of May, so high quality feed must be given, especially in the middle and later stages of pregnancy. Due to the needs of fetal growth and development and maternal metabolism, the feed quality should be improved and the feed quantity should be increased. To the end of pregnancy, a few days before giving birth, the feed concentration should be diluted, and the feed amount should be reduced by 1 minute, 3 pounds, 1 pound, 4.

(5) the lactation period of female foxes is from the end of May to June. Due to the need of lactation, the matching amount of diet of female foxes must consider the litter size and the age of young foxes. The growth and development of young foxes is related to the quantity and quality of breast milk within 3 weeks.
