Feeding and management of suckling deer

1 The milk secreted by a colostrum-fed female within 7 days after delivery is called colostrum. Aunts should eat colostrum for several hours after they are born. It is best to eat within 1-2 hours and no more than 8-10 hours at the latest. Colostrum is dark yellow and thick, more than the total dry matter of regular milk. In addition to less lactose in the total dry matter, other contents are more than regular milk, especially rich in protein, vitamin A, lipase, Ash, antibodies, phosphates, magnesium salts, etc. The protein contains a large number of immunoglobulins and plays an important role in enhancing the disease resistance of the deer. The magnesium in colostrum can help the deer out of the fetus. The primary absorption rate of colostrum immunoglobulin is highest in Aberdeen deer, which is about 50%. After 20 hours, it can only absorb 12%. After 36 hours, it can only absorb a small amount or not. Therefore, the sooner the deer feeds a sufficient amount of colostrum, the more immunoglobulins are in the blood, and the amount of immunoglobulin in the blood is related to the mortality of the deer. If a deer does not eat the deer's colostrum, the cow's colostrum will also have a certain effect. The amount of colostrum fed daily should be higher than that of regular milk, which can feed 1/6 of body weight. The number of times a day is not less than 4 times. The extruded colostrum should be fed immediately. If the milk temperature drops, the water bath should be heated to 36-38°C. If the temperature is too high, the colostrum will coagulate. If it is too low, it will cause the deer to squat. Whether deer can eat colostrum is an important indicator of the strength of life. If you do not eat colostrum 6-8 hours after birth, you will become weak and even die.
2 Adolescent deer Artificial lactation deer can eat breast milk on their own after birth. No manual feeding is required. Artificial breast-feeding is performed only under the following conditions: the mother deer of the deer is not strong, and the deer is not breast-feeding; the deer milk is insufficient or unable to lactate; Frailty can not stand after birth; doe died after delivery, can not find the deer doe; in order to carry out the necessary artificial domestication of the deer; the newborn deer captured from the wild and so on.
Artificial nursing mainly uses milk, goat milk, etc. to feed directly to the deer. Artificial nursing can be divided into short-term artificial nursing and long-term manual nursing. The short-term manual nursing is to train the deer to suck breast milk on their own; long-term manual nursing is to perform artificial breastfeeding for the whole lactation period when the deer cannot obtain the deer's milk. In artificial nursing, the supply of colostrum is still a major link. To ensure the supply of colostrum, the deer can grow strong, develop well, and have a high survival rate. On the contrary, it is prone to morbidity and death.
The specific method of artificial breastfeeding for Aberdeen deer is to put the sterilized milk (colostrum or regular milk) into a clean bottle, put on a pacifier, adjust the temperature to 36-38°C, hold the head of the deer by hand, and fix it. The pacifier is inserted into the mouth of the deer, and the bottle is pressed so that the milk slowly flows in. Do not rush. Breastfeeders can be used when large groups of artificial breastfeeding are used to save manpower. When you are breast-feeding, use a warm, damp cloth to wipe around the anus or pull the deer tail to promote excretion of meconium. The deer will die if they do not excrete feces and urine.
Before deer 3-5 days old, 480-960 grams of bovine colostrum is fed on the day (each time while feeding, the anus is wiped with warm and wet gauze to promote defecation); after 6 days of age, cow milk is fed 960-1080 grams per day. Adjust the amount of feeding once a day for 5 days, feeding 4 times per day and night, feeding every 7 hours during the day and every 7 hours at night; enter the maximum amount (1200 g) at 21-30 days; gradually increase the feed intake at 31 days. Increase, at this time began to reduce the amount of milk; 41 days of age, fed three times a day (720 grams); 61 days of age, fed twice a day (600 grams); to 80 days after the day, fed once (300 grams ); Weaning at 90 days. During this period, the green feed such as fresh quail should always be kept on the straw stand for the deer to eat freely.
The time, frequency and amount of breast-feeding should be determined based on the day of birth, birth weight and development of the deer.
3 Feeding of deer suckling deer should be supplemented early on feeding deer. This is due to the fact that the growth of lactation after deer delivery is slower than that of deer growth. If it is not supplemented, its nutrient cannot meet the needs of growth and development of deer. Supplementary feeding is not only to supplement nutrient deficiencies, but also to allow early exercise of digestive organs and physiological functions of the deer, and can quickly adapt to new feed conditions after weaning. After feeding on deer, the growth of the rumen and large intestine is faster than that of the real stomach and the small intestine, which is determined by the hereditary nature of the digestive tract of ruminants in the fiber. Therefore, in the lactation period, by supplementing feed, especially feeding some vegetable feeds and succulent feeds, to stimulate the digestive system of the pups, it can promote the expansion of gastrointestinal volume and increase the digestive capacity. It is of great significance to breed deers that are resistant to roughage and adaptability.
After 15-20 days of birth, the deer can feed a small amount of roughage and concentrate feed with the deer. At this time, small troughs can be placed in the protective enclosures of the deer to vote for some nutritious mixed concentrates. The proportion of mixed concentrate is generally: 50% of soybean cake, 10% of soybean, 30% of sorghum, and 10% of wheat bran. At the same time, add a small amount of salt, calcium carbonate and feed additives for puppies. Mix the concentrate with warm water and mix well. It has a porridge-like shape and is supplemented once a day in the initial period. The amount of supplement should not be too large to prevent leftovers. At the age of 20 days, each spotted deer replenished 50-100 grams of concentrated feed daily. As the age of the deer grows, the amount of supplementation should gradually increase. When we are weaning, the deer can feed 300-400 grams, and the deer can be more than 1 times more than the deer.
It is not necessary to supply roughage for suckling deer alone, but it can be eaten freely along with the deer, but the roughage for supply to the deer should be soft dry green feed and grass branches and leaves. After the deer harvested the roughage, the moisture of breast milk alone could not meet their physiological needs. At this time, a deer drinking device was added to enable the deer to drink water.

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.
