Methods of Improving Feed Conversion Efficiency in Bamboo Rat

Abstract

The invention discloses a method for improving the conversion rate of bamboo-rat feed. The method includes the following steps that 1, N male bamboo rats and 3N female bamboo rats are selected, wherein the weight of each male bamboo rat is 1.66-1.70 Kg, the length of each male bamboo rat is 20.5-23.7 cm, each male bamboo rat has a large head, a thick neck and strong constitution and is free of retrorse hair, the weight of each female bamboo rat is 1.38-1.42 K, the length of each female bamboo rat is 17.2-19.5 cm, the jawbone of each female bamboo rat is full, the abdomen of each female bamboorat is mellow and full, four limbs of each female bamboo rat are robust, and N families are built; 2, generation selection is conducted on the built N families, the feed conversion rate of each familyis calculated, the N male bamboo rats and the 3N female bamboo rats in the families with the feed conversion rate ranking in the top 30 are selected, and N families are built; 3, the step 2 is repeated until the feed conversion rate of bamboo rats of the same generation is lower than a set threshold. The method has the advantages that Chinese bamboo rats with high feed conversion rate can be quickly selected within a short period of time.

Description

technical field [0001] The invention relates to the field of raising bamboo rats. More specifically, the present invention relates to a method for improving the feed conversion rate of bamboo rats. Background technique [0002] The bamboo rat has a large body and a lot of meat, delicious taste, rich nutrition, thick and soft fur, and has high economic value and medicinal value. At present, it has been cultivated on a large scale and has become one of the breeding industries with greater economic benefits. Wild bamboo rats feed on the underground stems, roots, and twigs of bamboo, miscanthus, sweet potato, and corn. Under artificial domestication, the roughage of bamboo rats mainly consists of crude fiber rhizomes such as bamboo, sugarcane, miscanthus, and dried cassava. The roughage for raising bamboo rats in small-scale households is generally crop straw, and the concentrated feed is mainly corn, sweet potato, rice, rice bran and other agricultural and sideline products. ...

AI Technical Summary

Problems solved by technology

The roughage for raising bamboo rats in small-scale households is generally crop straw, and the concentrated feed is mainly corn, sweet potato, rice, rice bran and other agricultural and sideline products. For large-scale breeding of bamboo rats, it is necessary to plant pastures and roughage such as bamboo, emperor bamboo grass, and sugar cane. , using corn flour, soybean meal, fish meal, minerals, vitamins, trace elements, etc. to formulate a full-price bamboo rat concentrate feed. However, most of the current Chinese bamboo rats have the characteristics of large feed consumption and low feed conversion rate. Also known as feed remuneration and feed-to-meat ratio, it generally refers to the ratio of the weight of air-dried feed consumed per unit to the weight of animal products obtained. It is an indicator of feed efficiency in animal husbandry. For living organisms, the feed conversion rate can also be expressed as the consumed The ratio of feed amount to increased live weight, the heritability of the feed conversion rate of bamboo rats is low, and it is difficult to improve the feed conversion rate of bamboo rats in a short period of time through phenotypic selection;
