Inbreeding
by Paul Maywald

 

RULE:     SELECTION & ELIMINATION

BREEDING:   FATHER-DAUGHTER    MOTHER-SON   1/2 SISTER-BROTHER    SISTER-BROTHER

HEN:    THE HEN IS THE FOUNDATION FOR THE EGG THUS THE YOUNG CAN BE NO BETTER THAN THE HEN. PAIR, YOUNG HEN TO OLD COCK OR YOUNG TO YOUNG OR OLD HEN TO YOUNG COCK KEEP GENES HEALTHY.

INBREEDING:   CONTRIBUTES NOTHING NEW TO THE LINE. IT RESULTS IN A LINE BECOMING MORE HOMOZYGOUS OR PURE FOR CERTAIN QUALITIES WHICH MAY OR MAY NOT BE DESIRABLE TO THE BREEDER, DEPENDING ON BOTH CHANCE ARRANGEMENTS OF THE GENES AND THE GENETIC BASIS OF THE ORIGINAL STOCK.

OUTBREEDING:  TENDS TO HIDE DEFECTS, BUT IT DOES NOT ELIMINATE THEM. INBREEDING DISCLOSES THEM AS THE LINE BECOMES MORE HOMOZYGOUS, BUT IS NOT THE CAUSE OF THE DEFECT.

SELECTION:   IN AN INBRED LINE OF THE MOST DESIRABLE  INDIVIDUALS, IT ENABLES THE BREEDER MORE QUICKLY TO ELIMINATE DEFECTS.

OUTCROSSING:   IS A RISKY BUSINESS, BUT THE RISK CAN BE REDUCED IF THE BIRD COMES FROM A STUD, THE MEMBERS OF WHICH ARE (DISTANTLY OR CLOSELY RELATED TO ONE'S OWN STUD), BUT HAVE BEEN REARED IN A DIFFERENT PART OF THE COUNTRY. THIS OUTCROSS IS ESPECIALLY HELPFUL IN PROMOTING WHAT IS KNOWN AS "HYBRID VIGOR".

GOAL:    OF INBREEDING SHOULD BE THE ELIMINATION OF UNDESIRABLE TRAITS AND THE DOUBLING-UP OF DESIRABLE ONES THROUGH STRICT SELECTION AND RUTHLESS ELIMINATION.
