BREEDING.» 
The time of mating depends largely on the time when it is best for 
the kids to come. The period of gestation is from 147 to 155 days, 
and the time of mating is adjusted accordingly. 
BUCKS. 
Bucks to be used for breeding should be over 18 months of age. 
They should be kept in a thrifty, growing condition throughout the 
entire year, but particularly so during the mating season. Before 
breeding, the mohair should be clipped irom the underside of the 
buck. 
The number of does a buck may serve depends largely on the 
methods used. When the bucks are turned loose on the range with 
the herd there should not be more than 40 does to each buck. When 
the bucks are kept up in the daytime and fed grain in addition 
to pasturage, and are placed with the does only for the night, a buck 
ean often serve more than 50 does, especially if it is desired to have 
the kids come well distributed through about 30 or 35 days, as is 
usually the range practice. By careful handling of the bucks some 
growers have had good success using one buck for about 80 does. 
In such cases the bucks are well fed and are placed with the herd 
only at night. With the possible exception of a few nights during 
the breeding season, only half the bucks are ee with the herd 
one cee t and the other half the next night. They are mixed so that 
if there is an exceptionally thrifty one and one that is not thrifty, 
these are placed with the herd on the same night. No two bucks 
that fight are placed with the herd on any one night. 
DOES. 
Does come in heat about the latter part of August or the first of 
September, and, unless mated, have periods of about three days in 
heat at intervals until January. Before breeding the mohair should 
be clipped from the hind parts of the doe etl under the tail. 
The does sheuid be in good condition at the time of breeding. 
They should not be bred until they are 18 months of age. With 
small does it will often prove best to allow them still another year’s 
growth before breeding. This gives them a chance to attain full 
growth, and as dry young does they will furnish a greater amount 
of valuable mohair than if they are nursing kids. When small does 
are bred at 18 months of age and raise a kid during their third year, 
they often fail to have a Ind the next year and are usually per- 
= 
manently stunted, and their kids are generally smaii.
