Division of Animal Resources

 

The major tasks of the Division of Animal Resources include large scale production of experimental animals (pigs) through three units (molecular farm, Cheng-Yu pig farm and Specific Pathogen Free (SPF) farm), providing animal experimental housing, improving key indices of boar performance using genetic methods and supplying fresh boar semen.

The development of Specific Pathogen Free (SPF) pig production is fundamental to vaccine and drug research and animal farming for  producing pharmaceutical proteins.

Furthermore, the Division actively participates in cooperative efforts to improve farm management, segregated early weaning and batch production.

The Lee-Sung pig (5 males, 16 females) was introduced from National Taiwan University for SPF production to supply testing animal demand.

  • Central Performance Test 
    •  
      • Segregated Early Weaning (SEW) system was applied to achieve uniform feed and feeding conditions for assessing the performance of pure bred piglets from breeding farms and selecting genetically superior breeding animals].

            Testing piglets weighing 4-7 kg at 14-17 days of age were transported to the Central Performance Testing Station. The weight of the  animals was increased to 25 kg in a SEW nursery (Fig.21), and they were moved to test pens for performance testing when their weight reached 40-110 kg. The boars were publicly auctioned after passing  index selection and qualifying tests. Index selection was used to assess individual genetic potential, and average daily gain, feed efficiency, and back fat thickness were measured. The qualifying tests included normal bone structure, reproductive organs and semen quality. (Fig.22)

        Testing was conducted on 1,130 boars from 14 breeding farms during 2011. The nursery survival rate was 95.4%. Notably, 93.8% of test boars passed the tests. The performance test results were as follows: average boar age at 110 kg of 151 days, average daily gain of 1.078 kg; feed efficiency of 2.16 kg and back fat thickness of 1.31 cm. Approximately 90% of the pure-bred boars were sold (93.9%), with the average price per head being NT$ 32,000. Top boar with average daily gain of 1.183 kg sold for NT$ 200,000 (Table 6). The highest sale price in 2011 was for a Duroc boar, D502-01 (station ear mark D33454) (Fig. 23). The above results indicated that Central Performance Testing can select boars with superior genetic traits, and SEW can improve overall boar quality in Taiwan.

  • Supply of Fresh Semen
    •  
      • Fresh semen from 75 quality boars (including the breeds Landrace, Yorkshire, Duroc, and Taiwan Black) was purchased from the Central Performance Testing Station for the semen station. Fresh semen was provided to pig producers to accelerate genetic and reproduction improvement and to reduce production costs. A total of 30,689 doses of fresh semen were provided to 301 pig farms in 2011, and each quality boar used for semen production supplied an average of 504 doses of fresh semen for sale. (Fig. 24)The average farrowing rate for each insemination was 82.1 %. Moreover, litter size and average number of live piglets per litter were 11.8 and 10.5, respectively. Customers were highly satisfied with the results achieved by the Division.

  • Supply of Research Animals
    •  
      • In 2011, 752 pigs were made available for animal trials, 60 gilts served as transgenic recipients and 15 pigs were used for xenotransplantation, with all these animals being obtained from Cheng-Yu pig farm in Zao-Ciao town.

        Milk (645kg) from recombinant human Factor IX (rhFIX) transgenic sows was used for protein drug development in molecular farms during 2011 (Fig. 25). In accordance with Good Laboratory Practice (GLP) guidelines, animal feeding condition and animal care system were standardized and improved.

        In 2011, 809 secondary Specific Pathogen Free (SPF) pigs were supplied to academic institutions for research. Furthermore, 100 primary SPF pigs were produced via Cesarean section in the primary SPF pig unit, with a 6 week survival rate of 94.8 %. (Fig. 26)
