Embodiment 1

[0017] A hybrid breeding technology of Yulong Little Black Pig, specifically according to the following operation steps:

[0018] S1: Cultivate the binary male parent and the binary female parent, select the Tibetan pig in estrus as the female parent and the local black pig as the male parent for crossbreeding. After the Tibetan pig female parent gives birth, collect the sows as the binary female parent , reserve, select the Dahechang pig in estrus as the female parent and the wild boar as the male parent for crossbreeding. After the Dahechang pig female parent gives birth, collect the boar piglets as the binary male parent;

[0019] S2: Raise the binary female parent and the binary male parent, stock the binary female parent and the binary male parent separately, and feed corn 35%, wheat bran 15%, rice bran once a day by mass percentage during the stocking period 10%, fish meal 5%, shell meal 5%, salt 3%, potato 10%, weeds 15%, trace elements 2%, until the binary female paren...

Abstract

The invention discloses a hybridization breeding technology for Yulong small black pigs. The hybridization breeding technology includes the following specific steps of S1: breeding a second-generationmale parent and a second-generation female parent; S2: raising the second-generation female parent and the second-generation male parent; S3: cultivating a fourth-generation female parent; S4: cultivating fifth-generation piglets; S5: raising the fifth-generation piglets. Pig snowflake meat of the Yulong small black pigs cultivated with the technology has the remarkable advantage, and the Yulongsmall black pigs are rich in flavor, fine and smooth in meat quality, less in fat and high in nutritive value, and lean meat can be increased by 40% or above; the Yulong small black pigs are robust inphysique, pointed in mouth, long in head, thin in trotter, hard in bone and black and shiny and smooth in pelage, are good at running, have the specially-developed cardio-pulmonary function, and haveextremely-high disease resistance and cold resistance; adult Yulong small black pigs are slightly small in body size, are similar to wild pigs in appearance, and are long and pointed in mouth, suitable for digging and turning, narrow in face, less in wrinkle, thin and small in arms and legs, strong and compact and slightly black in pelage color.

Description

technical field [0001] The invention belongs to the technical field of animal breeding, and in particular relates to a hybrid breeding technology of Yulong Little Black Pig. Background technique [0002] With the development of the economy and the improvement of living standards, people's demand for food is not only satisfied with the abundance of quantity, but more and more people begin to pay attention to the quality and safety of food. Non-polluting and safe eco-labeled food emerges as the times require. In my country, eco-labeled food mainly includes three categories: organic food, green food and pollution-free food. The scale of development of eco-labeled food in my country is still very limited. The eco-labeled food entering the market is not recognized by most consumers, and the market occupies rate is extremely low. Secondly, due to the accelerated process of urbanization, the original original environment of the countryside has been changed. The breeding industry ...
