Feeding technique of bamboo rat

Bamboo rats like to be in a quiet, clean, dry environment with proper light and fresh air, and they are more active at night. Its activity law can be divided into activity cycle and rest cycle. Its sex likes to be warm, the living temperature is-8 Murray 35 ℃, and the optimum temperature is 8-28 ℃. Like to hide in the corner of the weak light, if placed in the sun, it will run incessantly, looking uneasy. When people blow into it, they immediately show their sharp, thick incisors and demonstrate with the sound of "whoo-hoo -".

Under the condition of artificial feeding, at the age of 4-5 months, the body weight above lkg began to mature, and then propagated after 6 months of age. Generally, more than 10 animals were bred every year. The body weight of young mice reached 0.5kg in 3 months, more than 1kg in 5 months, and the largest 2-3kg.

I. enclosure

Empty houses, cellars and air-raid shelters can be farmed, or 1.2X1.0x0.8m enclosures are made of bricks, separated into two houses with bricks, with a hole on the wall, one as an inner room and the other as a breeding ground. Group breeding 5 pairs / square meter, can also be caged.

1.2 Young mice

Refers to bamboo rats within 3 months of age after weaning. Feed with fresh, digestible and nutritious feed. Such as carrots, sweet potatoes, bamboo shoots. Succulent feed such as melon peel, as well as corn, wheat bran, dried steamed bread and other concentrate. At the same time, fish meal, bone meal, salt, vitamin and auxin were added to the diet to improve feed digestibility and promote the growth and development of young rats. The type of food must be relatively stable, and if there is any change, there should be a transitional period. The young rats were fed 14-17g a day, fed twice a day, less in the morning and more in the afternoon. The young rats were raised in pools according to their body weight and physical strength, with 4-5 rats in each cage. The weak ones should be raised separately to promote the physical recovery of young rats.

1.3 Adult mice

The adult mouse has strong disease resistance, rapid growth and development, and has a body weight of 1.2-1.5kg. It should be fed regularly and quantitatively, once in the morning and evening, 150-200g straw and 15-20g concentrate per day. The basic diet does not need to be changed all the year round, and there should be a transitional period if the change is made. Adult rats have fast-growing teeth and need to place a bamboo or hardwood stick in the cage to grind their teeth. Check every day whether the feces of bamboo rats are smooth and granular, like medicinal capsules. Pay attention to whether the coat color is bright, whether the activity is lively, if there is an accident should be dealt with in time.

Male mice are required to develop well and have a body weight above 1.3kg. Straight back, strong, prominent testicles, strong libido, tolerance to rough feeding, no fighting. The mating action is fast and the semen quality is good.

The quantity and quality of semen of male mice are related to nutrition, but can not be fed overfat. Green roughage is bamboo leaves, bamboo stalks, bamboo shoots, corn stalks, Reed stalks, sugarcane, carrots and so on. The matching diet is 55% corn meal, 20% wheat bran, 15% peanut bran, 3% bone meal and 7% fish meal.

Breeding rats were mated once or twice a day. The temperature is suitable in spring and autumn, the male rat is full of sexual desire and the semen quality is good. Estrus for 1-3 days at a time, and mating at night. The male-female mating ratio is 1:2-3, and the best one is 1-1.

The mother mouse requires high litter rate, strong motherhood, strong feeding ability and body weight above 1.2kg. Due to the growth and development of young mice, adult female mice still need to raise their young, so the diets of young and adult female rats are as follows: ① corn 55%, wheat bran 20%, peanut bran 15%, bone meal 3%, fish meal 7%. Add 0.5% salt and auxin to the total amount. ② bamboo meal 20%, flour 35%, corn meal 10%, soybean meal 13%, wheat bran 17%, fish meal 2%, bone meal 2%, salt 0.2%, sugar 0.8%. In addition, folic acid 1mg, nicotinic acid 20mg, zinc oxide 75mg, Dmurl methionine 400mg, potassium iodide 0.5mg, manganese sulfate 60mg, VA1500IU, VD31500IU, VB12 20mg, VB2 6mg, VE30mg were added per kilogram of feed. The above feed is mixed, kneaded into steamed bread or granulated with water, then dried or dried, and fed to bamboo rats.

The gestation period of maternal rats is 60 days, during which the feed should be clean, fresh, diversified and relatively stable. Mother rats should be raised separately after pregnancy, always keep the house clean, with dry and soft bedding grass. The delivery time is 2-4 hours, and the fastest delivery is 1-2 hours. 6-7 days before delivery, the nipple of the mother rat was exposed, the activity decreased and the movement was slow. Before giving birth, there is a "goo-goo -" sound from time to time. During delivery, the newborn mice are born together with the placenta and placenta. The mother rat eats the placenta and placenta while giving birth, and finally bites off the umbilical cord and purifies the amniotic fluid from the offspring. At this time, you can hear the squeak of the young mouse. 12 hours after the mother gave birth, she began to breast-feed her offspring.
