Breeding method of low-cost high-quality stress-resistant meat rabbit complete set line suitable for early marketing

Abstract

The invention discloses a breeding method of a low-cost high-quality stress-resistant meat rabbit complete set line suitable for early marketing, and belongs to the technical field of livestock breeding. The breeding method comprises the following steps of: S1, constructing the breeding base groups of a European white rabbit S86 line, a Zika large New Zealand rabbit F86 line and a Qixing meat rabbit D99 line, and carrying out subculture breeding; S2, carrying out longitude and latitude hybridization among the groups in the S1, and determining a matching mode; S3, according to the matching mode determined in S2, taking the European white rabbit S86 line as a first male parent and the Zika large New Zealand rabbit F86 as a first female parent, and carrying out hybridization to obtain a matching line parent generation male parent SF; and S4, hybridizing the Qixing meat rabbit D99 serving as a terminal female parent with the parent generation male parent SF to obtain a high-quality commercial rabbit. The complete set line cultivated by the method has the consistent body shape and appearance, and has a good body structure, developed leg and hip muscles, a low breed production cost, high stress resistance, low material consumption during early marketing, a high meat yield and excellent meat quality.

Description

technical field [0001] The invention relates to a method for cultivating low-cost, high-quality and stress-resistant meat rabbit matching lines suitable for early marketing, and belongs to the technical field of livestock breeding. Background technique [0002] my country is the largest country in the world for raising rabbits. Since 1996, the amount of rabbits slaughtered and the output of rabbit meat have ranked first in the world. The southwest region is the most important meat rabbit production and consumption area in my country, and the annual slaughter volume and consumption account for more than 60% and 70% of the national total respectively. Southwest China is located in the subtropical monsoon climate zone, most of which have the climate characteristics of high temperature and high humidity in summer and low temperature and high humidity in winter. In terms of breeding scale, the development presents a pattern of moderate scale as the main body, slow development of...

AI Technical Summary

Problems solved by technology

Since the imported matching lines are all selected and bred under the conditions of environmental control rabbit house combined with artificial insemination and periodic breeding mode, the nutritional level of feed is high, and the feed consumption is large. The adaptability to the environment and feeding methods is poor, and the excellent production performance has not been fully utilized. The carcasses of commercial rabbits are not plump, especially when the slaughter rate is only about 46% to 47% when the 2kg body weight is on the market, and the hydraulic power is low at this time. , the meat quality is poor, far from meeting consumer demand
