What is the pedigree of miniature dairy goats?
Mini dairy goats are new breeds created by breeding a
full-size dairy doe to a Nigerian Dwarf buck. The goal is to
produce a mid-size dairy goat that, other than the smaller
size, looks like the standard-sized breed.
Many people have been confused by the percentages listed on
These percentages show
the ratio of standard to Nigerian genetics in the mini dairy
Another common misunderstanding is the meaning of the
“generation” of a mini dairy goat.
Below is an attempt to explain where
these percentages and terms
Understanding Generations: A
first generation (F1) is either a cross between a Nigerian
Dwarf (ND) and a standard-sized doe (one of the recognized
dairy breeds) OR a cross between a miniature dairy goat and
a standard-sized goat, or Nigerian Dwarf. Any of these
crosses result in a first-generation miniature dairy goat.
Breeding an F1 to another F1
creates a second generation (F2). F2 x F2 = F3, and so on.
or standard breed]
are considered 0 generation in the mini
The generation of the kid is always one generation higher
than the lowest generation of a parent. For example, if you
breed an F3 to an F1, the kid is an F2. Even if you breed an
F6 to an F1, the kid will only be an F2.
Let’s say you’re breeding a 75/25 mini buck to a 62.50/37.50
Take the “standard” part of the percentage from
both parents (75 and 62.50),
add them together (75 + 62.50
= 137.50), and divide the result by 2. That gives you 68.75,
which is the percentage of standard genetics for the
offspring. This is the first number shown in a percentage.
Next, to calculate the percentage of “Nigerian” genetics for
subtract 100 from 68.75 (the standard percentage you
calculated earlier), which equals -31.25. This is the
percentage of Nigerian genetics for the offspring, which is
the second number shown in a percentage.
standard/Nigerian genetic percentages for kids of those
parents will be 68.75/31.25.
Here is a pattern to follow for calculating percentages:
Sire: 75/25, Dam: 62.50/37.50
+ 62.50 = 137.50
137.50 ÷ 2 = 68.75
68.75 - 100 = -31.25
Final result = 68.75/31.25
