Potato, the subterranean stem of corn, root, spray is eat, and the bamboo rat roughage under the conditions of artificial domestication is mainly with bamboo, sugarcane, Chinese silvergrass, wood
Potato is dry to be waited based on crude fibre class rhizome.It is typically mostly agricultural crop straw that family raises bamboo rat roughage on a small scale, and concentrated feed is main
Based on some agricultural byproducts such as corn, sweet potato, rice, rice bran, large-scale cultivation bamboo rat, it is necessary to plant bamboo, hybrid giant napier, sweet
The herbages such as sugarcane and roughage, coordinate full price bamboo rat smart with corn flour, dregs of beans, fish meal, mineral matter, vitamin, trace element etc.
There is the characteristics of feed consumption is big, feed conversion rate is low more in feed, still, current Rhizomys sinesis, feed conversion rate is also referred to as
For the price of deed, feedstuff-meat ratio, refer to the ratio of consumption unit air-dry feeds weight and resulting animal product weight, be herding
The index of feed efficiency is represented in industry, feed conversion rate is also referred to as the forage volume consumed and increased work for live body
The ratio of weight, the genetic force of the feed conversion rate of Rhizomys sinesis are relatively low, it is difficult to are improved in the short period of time by Phenotypic Selection
The feed conversion rate of Rhizomys sinesis；
Whether family-raise or large-scale cultivation, the cost shared by feed be can not ignore, as feed is former
The continuous growth that material adds, how there is at seed selection the Rhizomys sinesis of high food conversion, fundamentally strengthen Rhizomys sinesis
Raise benefit, it is current urgent problem.
The content of the invention
It is an object of the invention to solve at least the above, and provide the advantages of at least will be described later.
It is a still further object of the present invention to provide a kind of method for improving bamboo rat feed conversion rate, it can be in a short time
Quick breeding has the Rhizomys sinesis of high feed conversion rate.
In order to realize according to object of the present invention and further advantage, there is provided a kind of raising bamboo rat feed conversion rate
Method, comprise the following steps：
Step 1: choosing N number of male bamboo rat and 3N female bamboo rats, include 1 male bamboo rat and 3 according to each family
Only female bamboo rat establishes N number of family, wherein, N >=60；
Step 2: carrying out the seed selection of a generation respectively to N number of family of foundation, the feed conversion rate of each family is counted,
And sorted according to feed conversion rate size for each family, choose N of the feed conversion rate ranking in the family of first 30 only males
Bamboo rat and 3N only female bamboo rat, establish N number of family；
Step 3: repeat step two, until the feed conversion rate of the bamboo rat of same generation is less than given threshold；
Wherein, between the male bamboo rat of each family and female bamboo rat within 3 generations without blood ties.
Preferably, the selection standard of male bamboo rat is in step 1：Body weight 1.66Kg-1.70Kg, the long 20.5cm- of body
23.7cm, the big neck of head is thick, and constitution is solid without inverse hair；
The selection standard of female bamboo rat is in step 1：Body weight 1.38Kg-1.42Kg, the long 17.2cm-19.5cm of body, jawbone
Full, belly is mellow and full, and four limbs are sane.
Preferably, total weight X when each family bamboo rat offspring wean is counted in step 21It is total when Kg, bamboo rat offspring adult
Body weight X2Kg and bamboo rat offspring wean to total feed intake X during bamboo rat offspring adult3Kg, then each family feed conversion rate
Preferably, ranking is counted in step 2 and each grows up bamboo rat for weaning weight in each family of first 30
X4Kg, each bamboo rat body weight X that grows up5Kg, each family are always searched for food number of days n, daily ingestion amount WiKg, daily feeding bamboo rat offspring's
Number Ji, calculate the feed conversion rate of each adult offspring of each family
The selection standard of male bamboo rat is in step 2：Food conversions of its feed conversion rate Z not less than family where it
Rate Y, and the big neck of head is thick, constitution is solid without inverse hair；
The selection standard of female bamboo rat is in step 2：Its feed conversion rate Z turns not less than the feed of family where it
Rate Y, and jawbone is full, belly is mellow and full, and four limbs are sane.
