3. Rule of testing
3.1 Each year, the frequency of Pig Performance Testing held by the Foundation will be based on the facility capacity. All pig herds registered for testing are allowed to send piglets for testing. Piglets for testing shall be aged 13 to 17 days and weighing 4.0 to 7.0 kg..
3.2 Each testing unit shall be three to five male piglets of the same litter. The testing boars from the same litter shall be judged as disqualified littermates when the verification of their genotypes were not the same full siblings of parentage. The disqualified boars from the verificated litter shall be castrated with medicine and not be returned to the owners.
3.3 If, among same litter, there is any piglet with defects, such as hereditary hernia or atresia ani or if there are less than 6 surviving piglets in one litter, the pigs are not qualified for testing. No acceptance on Landrace and Yorkshire piglets with 6 teats or less on either side. No acceptance on Duroc piglets with 5 teats or less on either side.
3.4 If no Pedigree Registration Certificate of tested pigs is provided within two months, the pigs shall be sent back to the farm. Meantime, a testing fee shall be charged according to the duration the pigs have stayed in the test station of the Foundation.
3.5 The genotype of Porcine Stress Syndrome (PSS) shall be normal AA in Landrace, Yorkshire, Duroc, Berkshire, TLRI Black Nm. 1, Meishan and KHAPS Black. Any pig with PSS genotypes not AA shall be disqualified and a testing fee shall be charged.
3.6 The genotype of Heart Fatty Acid Binding Protein (HFABP) shall be HH6, HL5, HL4 and HL3 in Duroc. Any pig with HFABP genotypes not listed shall be disqualified and a testing fee shall be charged.
4. The testing procedure and evaluation
4.1 Every pig in the test station shall be kept individually and will be offered 10 kg of preparatory ration. Afterwards, the standardized ration for performance test will substitute the original ration. The formula of standardized ration and preparatory ration can be seen in Appendix 1.
4.2 After quarantine observation, individual pig weighing 40 + 2 kg (gilts 30 + 2 kg) will start the test till 150 days old to finish the test. Those pigs weighing 107 kg or less (gilts 97 kg) shall be continuously tested till they are 107 kg (gilts 97 kg) for the growth performance test. The testing period for Berkshire, TLRI Black No.1 and Meishan breed is from 80 to 180 days of age.
4.3 If the breeding pigs are still under 107 kg (gilts 97 kg) at 168 days of age, the test is considered finished and the pigs shall be judged as disqualified. (Boars shall be castrated with medicine and not be returned to the owners.) The income from selling the culled pigs shall be returned to the owner.
4.4 Test pigs are fed ad libitum with pellet ration and the cumulatively consumed feed is computed.
4.5 At the end of test, the backfat thickness shall be calculated by the adjusting formula at the fifth rib, last rib and the last lumbar vertebra.
4.6 At the end of test, a Performance Index shall be calculated according to three traits, average daily gain, average feed efficiency and average backfat thickness. All the calculation formulae and the evaluation methods of Performance Testing can be seen in Appendix 2.
5. Disease prevention and hygiene
5.1 Before the test, the pigs shall not be vaccinated against hog cholera or foot-and-mouth disease. Other vaccination records should be kept and handed in by the farm veterinarian.
5.2 All pigs shall be dipped and sprayed with disinfectant before entering the test station. No persons, vehicles, objects or equipment are allowed to enter the test farm without permission.
5.3 Health Certificate for Tested Pigs (T/5) shall be handed in at the same time when tested pigs arrive at the station. The farm veterinarian should complete the form with a signature for the provided data.
5.4 If a farm has been in the period of reportable animal diseases, farm owners should not send the pigs for testing. If there is any suspicious case, the test station is authorized to refuse the application of any testing pigs.
5.5 When any pig is found out to carry a reportable animal disease, the station staff should notify the owner and the local disease prevention station immediately and follow the instruction of animal disease prevention specialist.
6.1 At the end of test, the total expenses of ration consumption shall be apportioned among the pig units. One unit is one pig. The Foundation shall approve the cost according to the test unit and notify the owner individually. Pigs dismissed from the performance test due to particular reasons shall be handled in accordance with the following:
6.1.1 No fee shall be charged if the pig dies before the auction.
6.1.2 If the boar is disqualified, the owner shall pay (i) the total fee: if the pig has stayed in the station for more than 3 months; (ii) 3/4 of the total fee: if the pig has stayed in the station for more than 2 months but less than 90 days; (iii) 1/2 of the total fee: if the pig has stayed in the station for less than 60 days.
6.2 When an auction is completed, the base price shall go to the owner. The 70% of the exceeded price shall go to the owner and the owner is expected to donate the remaining 30% to the Foundation to help the development of this program.
