Livestock Gender Regulation

What is Livestock Gender Regulation

Principles of
Sperm Coagulation

The gender-regulating protein for livestocks selectively binds to and coagulates sperms.
The mobility of coagulated sperms is inhibited, thereby hindering the insemination of eggs.
The non-coagulated sperms move normally and fertilize eggs to produce livestocks of desired gender.

Principles of
Producing Females

The gender-regulating protein only binds to and coagulates male-producing Y-sperms.
The X-sperms fertilize eggs inside uterus after artificial insemination and produce female livestocks.

Principles of
Producing Males

The protein bound to Y-sperms enhances the mobility of Y-sperms.
The male-producing Y-sperms meet with eggs quicker than X-sperms and fertilize.

Necessity of Livestock
Gender Regulation

  • Cow Farms
    • Rapid increase in farm breeding population through cow production
    • Maintain a consistent breeding population through stable production of excellent cow candidate livestocks
    • Milk production through high-producing cow breeding and high-producing beef cattle production
    • Reduction of feeding and management cost through breeding and raising high-producing cows
    • Maximization of management efficiency and profit through planned reproduction and breeding
    • Enhancement of livestock improvement speed through mass breeding of excellent cows
    • Secure large number of high-producing cattle in a short period of time using inseminated egg transplantation technology (OPU/IVF)
  • Pig Farms
    • Breeding pig farms maximize profits by reducing feed and management costs through high-producing sow roduction
    • General pig farms produce profit through pork carcass prices and selective production of highly preferred sows
    • Castration cost from boar production is reduced
  • Goat and Sheep Farms
    • Expansion of farm breeding scale through mass breeding of milk goats
    • Retain large quantities of excellent milk goats through improvement of milk goat breeds
    • Commercialization and profit gain through mass production of goat milk
  • Horse Farms
    • Safe mass breeding and population retain of mares for riding horses
    • Quick expansion of horse breeding population using frozen semen and artificial insemination technology

Importance of Livestock Gender Regulation

  • Importance of Gender Regulation (Cows)
    • Breed improvement period is reduced by over 50%
    • Breeding farms can produce high profits through planned cow production
    • Breeding cost is reduced and productivity is maximized through systemized breeding
    • Excellent gene pool is procured through mass-breeding of excellent cows
    • Costs including undesired feeding are reduced through planned cow production
  • Crises of Livestock Industry and Strategies
    Categories Crises Measures
    International
    Factor    		 FTA
    Agreement
    • Secure mass-production technology for high-producing cows
    • Obtain qualitative competency in beef through cow improvement
    • Fortify price competency through production of high-quality beef
    • Differentiating strategies through branding and functional meat production
    Domestic
    Factor    		 Cost
    Increase
    • Cost-saving through exclusion of cows with low-quantitative traits
    • Cost-saving through development of novel feed formulation
    • Cost-saving through scale enhancement of breeding
    • Cost-saving through digitalization of specification management
    • Development of breeding technology for mass-producing cows with excellent traits
    • Development of technologies for breeding and pregnancy rate improvement

Features of Livestock Improvement Determining Genetic Traits

  • The key objectives of livestock profit, quantitative traits (milk quantity and body weight), are regulated with various genes
  • Environmental factors are highly influential
  • Excellent seeds and fertile land are key to the production of excellent livestocks
  • Excellent qualitative traits can be secured by breeding bulls and cows of excellent genes
