Pure Breed Registration of Swine in
Taiwan
Yung - Yi Sung
Department of Animal Science
National Taiwan University
The pure breed swine registry
system is establised in 1975. ht the same time the Central Testing Station (
GTS ) is opened for performance testing of boars in Taiwan Hereby elite herd
evaluation and national nuclear herds scheme are proceed by steps and stages
to form the four parts of swine improvement in Taiwan (Chyr, 1987). Pure breed
swine registration in Taiwan is not only performing to keep the pure strain
type but for record its lifetime levels of production as it is closly associated
with breeding. In 1983, the registration system has been tremendous change as
it is involve in machinery by computer. Other hand, pedigrees of stock list,
collection stocks data in who or whos' herds codifying its performance records
and search for family selection to advanced registration and award are all
computerized to do it at once.
The flow chart of proaedure and its
brief is shown in Fig.1. The mating data is input, checking their farrowing
record and pedigree than output the registration diploma are all computerized.
The number of registration pigs and of herds changed in decade and registration
of each breed numbers are shown in Fig.2 and Fig.3 respectively.
Reproductive Performance
Registration
The perforoanoe testing is the most
important for providing aoourarte information in practiae. To encou- ragement
eaoh herd to take over the littering ability teat on farm, the repreduetive
performanae registry is put in practioe.
l. Sow: be passed the test of
littering ability. Its litter size are over 10 head in uncolor breeds and 8 head
in color breads, and pigling survival rate at 3 weeks of age are net less than
80%. The litter weight and its variation at 3 weeks of age are Judged.
2. Boar: on boars 5 progeny from 3
different sows have possessed reproductive performance registration will acquire
the boar's reproductive performance registration.
Neat Productive Performance
Registration
There are boar's CTS of Pig
Research Institute in chunan ~ Progeny Testing Station (PTS) of Provinoial
Livestock Research Institute in Shinhua and also encourage of on farm testing to
take over the performance testing for meat productivity registration since the
CTS and PTS can provide a uniform environment for growing and it is possible to
improvement estimation of its genotype (Sung et al., 1990). So only the results
of CTS and PTS are registried by Counoil of Registration, Swine Improvement
Foundation of Taiwan. The reproductive performance registration and meat
productive performance registration are twin star regulation of pig
registration.
1. Mew boar, which passed the CTS
or PTS individual testing (direct), or 3 progeny of sow/boar each breed from 3
different boars/sows are passed CTS or PTS testing, which sow/boar can acquire
meat productive performance registration (progeny test, indirect).
Super Reproductive Performance
Registration
i. e. Silver Medal Pig
There are two categories to
estimate the genotype of the reproductive performance on sows either the
productive ability is proven by its progeny or can produce more pigling in a
short peroid. The sow which passed the teat of littering ability seguential over
3 times within 15 months or 5 progeny breed from different 3 boars are possesed
the reproductive performance registration, and on boar, over 20 offspring from 5
different sows are possesed reproductive performance registration which also
wi1l award the super reproductive performance registry i. e. silver medal pig.
The number of silver meda1 pigs registried in decade are in Table 1.
Super Meat Productive Performance
Registration
i. e. Golden Modal Pig
There are a lot of herds possession
the super meat productive performance registration i. e. golden medal pigs, mean
that the boar or/and sow acguire both reproduction and meat productive
performance registrations and. while it have been proven by progeny are award
the golden medal pig price. The accumulation of super meat productive
performance registry pigs number and it owner herds number are shown in Table 2.
Mei - hua Prize Accompanied with
Golden Medal Pig
In 1985, the Mei-hua prize is lst
award accompanied with golden medal pigs which its all grand - parents and both
parents are registered in Taiwan herdbook. This honor prize is award to
encourage the elite breeder who breed golden medal pig on self - absorption and
make a contribution to splay their good gene all around in Taiwan. The number of
Mei - hua prize pigs and its owner's herd numbers are in Table 3. It shows that
the numbers of prize pigs are increase year by year and a new prize "Twin Mei -
hua" is establised in 199l to encourage that which grand - grand parents of Mei
- hua pig are all registered in Taiwan herdbook.
