Abstract

The invention relates to a Nubia-Longlin crossbred goat breeding and cultivating method. Through introducing the good genes of Nubia goats which are large in size, high in reproductive rate and quick in growth, the method enables a new strain (cultivated Longlin black goats) to be high in adaptability and disease resistance and be fully black in hair. The method overcomes the defects of a single type of crossbred black goats, and greatly improves the survival rate of lambs. Meanwhile, the crossbred goats are large in size, are quick in early growth, are high in breading rate, are high in meat productivity, are fresh and tender in meat, and are high in nutritive value of meat.

Description

technical field [0001] The invention relates to the field of hybrid breeding of goats, in particular to a Nubian-Longlin hybrid goat and a breeding method thereof.
