With Al, the cost of using superior sires
can be spread over more sows. With SGI semen, the cost is shared with hog producers
throughout the world. For these reasons superior semen is available at a cost below what a
producer may be presently encountering with natural service. (For the full value of
superior semen see page 5.)
-
More rapid improvement in the traits that result
in greater profits is possible because of the wider boar selection available. By using
EPDS, indexes, and breeding value scores on production, carcass, reproduction and visual
traits, a boar can be selected that is strong in the areas needed to make the most rapid
improvement with a particular group of sows.
-
Al will allow introduction of new genetic
material, with a reduced risk of disease transmission and without the introduction of
internal and external parasites. (See page 8 for a complete description of the health
advancements possible through Al).
-
Al is the most economical method of servicing a
large or small group of females, by reducing the boar power needed. A more uniform pig
crop will result through intensive use of fewer and superior boars.
-
Natural heat synchronization can be achieved by
weaning a group of females at the same time. (See page 26 for methods that can be utilized
to synchronize sows or gilts.) The use of Al will result in the full benefits of this
important management tool, without the added cost of maintaining the extra boar power
needed for an extensive periodic breeding schedule.
-
Use of Al will eliminate many of the problems
encountered in maintaining and utilizing boars such as: isolation and testing of boars
prior to introduction into the herd; special care and facilities to prevent heat stress or
injury; size differences between the boar and sow or gilt; lack of libido or infertility
of boars at critical times, resulting in the disruption of breeding and farrowing
schedules; injuries to boars, sows, and gilts during breeding and danger to workers in
handling boars.
-
Al can be used extensively in the development of
sound and functional rotational or terminal crossbreeding programs. (See page 6) Swine
Genetics' personnel will assist in the development of a breeding program through semen
selection that will blend performance, reproduction and carcass traits into the most
profitable total production program.
