Fertility management during the breeding period

The time from the splitting of the fox weaning to the removal of the skin is referred to as the breeding period. The following feeding and management work should be done during this period.

1. Breeding in the rearing period

The young fox grows rapidly during the period of 2 to 5 months. It must supply enough nutrients to meet its needs. Until the fox enters 6 months of age, its energy needs decrease.

Insufficient energy supply can cause growth retardation, and a severe lack will lead to weight loss and dull coat color. The fat in the feed is fresh, and the oxidation of the fat reduces the nutrient use of essential fatty acids. Breeding animals are prone to yellow-lipid disease. If fats in the feed are found to be oxidized or yellow follicles develop in young foxes, oxidized fat should be stopped or the vitamin E supply in the diet should be increased. 8 For a 25-week old fox, in order to obtain maximum nitrogen storage, it is necessary to provide a protein that accounts for more than 41% of the dry matter quality of the feed. When the content of digestible protein in the adult fox diet was less than 30% of the metabolizable energy, the young fox had a normal body weight but the growth rate of body length slowed down. About 5 to 6 months of age will grow to adult fox size.

The young fox has a strong metabolism and high feed utilization rate. It requires full nutrition for the diet, clean, easy to digest, fresh, and good feed quality. The amount of feed should be sufficient to eat without food. In the breeding period, the occurrence of anti-nutrition deficiency diseases should be supplemented with inorganic salts, various vitamins, trace elements, yeast powder, vitamin A, vitamin B1, B2, vitamin C, and sodium selenite E powder. Recharge to meet nutritional needs.

Within 100 to 150 days after the birth of the young fox, the growth and development are particularly fast. It is the period during which the bones and muscles grow rapidly. Especially around the age of 2 months after weaning, it is a crucial period for determining the size of the body. Therefore, we must pay attention to increase the amount of feed in a timely manner, and we must not be hungry and full. The supply of protein in this summer diet must be kept above 45g per day. Later, as the growth rate slows, the protein supply can gradually decrease, but each day can still not be less than 35g. If the protein supply is insufficient or nutrition is not sufficient, the future height and height of the young fox will be directly affected. Missed this period, feed no matter how good it grows, it can only grow into a rough, grow into a short thick fat.

Intestinal localization was administered to reduce adverse effects.

Targeted site-specific release:


Two hours in gastric juice will not disintegrate or crack, dissolve within thirty minutes of disintegrating juice, providing a perfect solution for protein and peptide drugs and probiotics.


Enteric coated gelatin hollow capsule is made of gelatin and enteric coating material in gastric juice it will not collapse, but will release in the intestines as a collapse of a target product . It is often used for special packaging of drugs and health cae products which are irritating to the stomach or unstable under acid, or dissolved and effected in the intestine.

Intestinal location administration can improve the efficacy of drugs, reduce the dose and the adverse reaction, brings the convenience to patients. Moreover , it can avoid the degradation of gral protein, polypeptide or health care products and provide the best absorption sites for them.
