The method of improving the reproduction rate of bamboo rodents

Secondary seed selection and repeated mating

First of all, try to choose good individuals when buying seeds. Then, through self-breeding and self-breeding, we select those offspring who give birth to more than four babies a year, each with more than four offspring, and leave 30 murmurs-35-day-old weaned weight of more than 250g to breed. Through the second selection, the reproduction rate and litter size of female rats can be increased by more than 80%. There are two best mating times for mother rats after giving birth and after weaning. The first time is called "blood matching". Unskilled ones are often difficult to match, so beginners should firmly seize this opportunity after weaning. Immediately after weaning, the female rat is caught to breed with the male beaver, and the male and female are separated about an hour after mating, and half a day later, it is called repeated breeding, which can increase the number of offspring by more than 50%.

The proportion of male and female rats should be appropriate.

Theoretically, it is inferred that one male belt, two females or three females is the most suitable. However, practice has proved that this conjecture is wrong under the current technical conditions. As the gregarious work of most breeders is not done well, males and females often do not combine temporarily until they are adults. Because bamboo rats have a strong memory and are not original spouses, they often live together for 3 months before they adapt to each other and mate. After giving birth, the male and female are separated, and it takes a period of time for the male and female to get used to it after weaning. Therefore, 1 male multi-female breed has a long adaptation period and low reproduction rate, 1 male and 1 female can guarantee 4 murmurs 5 births a year, while 1 male multiple females can only get 2 Murray 3 births a year.

Carefully protect the fetus and wean at the right time

Miscarriage after pregnancy or eating after 20 days of lactation is caused by lack of water in feed. After 1 month of pregnancy, bamboo rats should be fed with succulent fresh and tender green fodder, 10 days before delivery to postpartum to weaning, and 20 Mel 30 grams of sweet potatoes and horseshoes every day. At the same time, bone meal and multi-vitamins were added to the concentrate, and the bamboo rats were weaned for 35 days after delivery.

Meticulous ingredients to ensure nutrition

Every day, we have to supply 150ml / 200g, variety 2muri / 200g / day, three kinds of raw materials. Concentrate (generally using full-price chicken feed for meat) 20MUE 40g. Concentrate porridge with salt and mineral feed. 80% of the raw material is required to be fresh. The growth, development and reproduction of bamboo rats will stop if they are fed with coarse or moldy and deteriorated concentrate.

The raw material is sufficient, the fresh and tender surface material can not be interrupted.

Bamboo rats are plant-eating animals, hiding in caves during the day and looking for food at night. There is little coarse material, and the beaver is often hungry, even if the concentrate is enough, it will affect reproduction. Generally speaking, the green coarse material is thrown before leaving work in the afternoon, and when the nest room is cleaned the next morning, there is still a lot of fresh green coarse material that can not be finished, so the supply is reasonable; if there are only some unfinished old bamboo poles in the pond (which are for bamboo rats to grind their teeth, the nutritional value is very low), it means that the coarse material is insufficient. Fresh and green coarse materials are interrupted, the living conditions of bamboo rats are not satisfied, and reproduction will stop.

Clean and hygienic, comfortable life

When raising bamboo rats in this professional household, the quantity of fine roughage is large and the quality is good, but they do not pay attention to cleanliness and hygiene. The nest of bamboo rats is damp and cold, and bamboo rats can hardly find a dry place to sleep. If it goes on like this, no matter how good the feed is, it will not breed.

The environment is quiet and the temperature is suitable.

Moving, noise, bright light and noise stimulation, man-made worry, bamboo rats will stop 2murmuri for 3 months not to breed, even if it is difficult to match. The suitable temperature for bamboo rat reproduction is 10 Mel 28 degrees, and the nutritional condition is good. Take appropriate cooling protection measures, otherwise the mother rat will be thirsty to eat offspring or die. When the temperature is below 5 degrees, the room should be heated by a long fire, or a double-layer plastic film should be covered above the nest pool to keep warm, and the nest grass should be thickened to give birth in winter in order to survive.
