It was important breeding strategy for dairy farmer by mating simulation system to choose adapted breeding bull and improve dairy production, these genetic information of the candidate dairy bulls from data editing would link the imported frozen semen database, then we could know more imported data. Took the DHI cow NO. of ‘99060201’ for instance, which was the fourth lactation and the latest six tested milk data, the mean of the 305-2X-ME milk yield (305MY) was 8362 ± 194 kg and the somatic cell count score was 5.67 ± 0.94, and the data source from 'Dairy cloud information service in Taiwan' web site (www.tlri.gov.tw). This dairy cow was likely some problem with high production milk yield with subclinical mastitis. If we used mating simulation system to choose 20% bull select intensity grade for the SCS and 50% for the MY, after the computer calculation, there were 15,439 bull were choose and we further assessed the cow with slope rump angle (RA), the ‘007HO08778’ bull of the NAAB code was considerable. We could find the 'Predicted Transmitting Abilities' for Milk yield (PTAM), the 'Predicted Transmitting Abilities' for SCS and the 'Standard Transmitting Abilities' for RA were 352.9 kg, 2.7 and -1.7% for this bull, respectively. That means we could predict the genetic improved volume were increase 352.9 kg, reduced 2.7 score for the SCS and then corrected 1.7% of the RA mean of same period for the offspring dairy cows, respectively. It was favorable for us to take corresponded breeding method for the different performance of dairy cattle by using the mating simulation system.

The aim of this study was to investigate the DNA sequence polymorphism of pituitary specific transcription factor (POU1f1) and Calpastatin (CAST) in Nubian goat. Two groups of primers were designed to amplify DNA fragments of Nubian goat and then applied two groups of appropriate primers to sequence. The sequence of POU1f1 was compared with the sequence of DQ826413 in GenBank. It was found that there were 8 site substitutions between positions 10-446 of the pituitary-specific transcription factor gene in 91 Nubian goats. And CT was replaced with TC at position 18-19. Three positions differed from the alignment sequence between positions 45-370. There were T, G, T/G; G, T, G/T and C, T, C/T nucleotide type at positions 48, 102 and 365, respectively. There were 6 sequence types at positions 437-439. The sequence of the CAST obtained was compared with the sequence of DQ414516, showed that (1) there were 18 site substitutions in the 254 bp fragment of CAST gene of 174 Nubian goats, six nucleotide variations were transition substitution, and position 157 of all goat CAST gene had G-A transition substitution. (2) There were 0-6 repeats of 5'-GT 2 bp after position 60. (3) At position 63, there were T, G and T / G nucleotide types. Based on the above results, it was found that the DNA sequence analysis of POU1f1 and CAST gene in Nubian goat could produce more polymorphism, which would be applied to Nubian goat economic performance related research.

Duroc (D), Yorkshire (Y) and Landrace (L) pigs were tested for growth performance at Hsinhua Station. The off-tested age was on the weight of 110kg (100kg for gilt) or by 160+7 days of age. A total of 4,713 pig blood samples was collected during the sum of 42 classes from class 201101 to class 201604, in which were 2,482 D boars, 201 D gilts, 1,154 L boars, 313 L gilts, 466 Y boars and 97 Y gilts. Genetic marker of SY11 on chromosome X located at 73cM was designated as the skeletal integrity gene. The variation of DNA fragment size of 9 fragments were 161~177bp with a 2bp difference in size. Analysis on allelic variants in various breed and gender by using a higher pig head sold in auction, there were 175+0 and 171+0 genotypes in D boars, 171+4 and 175+0 genotypes in D gilts, 171+0 and 167+0 genotypes in L boars, 167+4 and 171+0 genotypes in L gilts, 171+0 and 169+0 genotypes in Y boars, 171+0 and 169+2 genotypes in Y gilts. Major allelic variants of skeletal integrity gene regardless of gender were 175, 171 and 167bp in D, 171 and 167bp in L, and 171 and 169bp in Y, respectively. Conformation contest was carried out in each class to select objectively a champion of tall pig in each breed and each gender, hence, a total of 204 head of champion pig with a tall conformation was selected. The major allelic genotype for those of tall champion pigs were shown as 175+0, 171+0 and 171+0 in D, L and Y, respectively. Utilization of allelic variants of the skeletal integrity gene on sexual chromosome as gene barcodes with conformation data to select tall pig lines within breed, it could be beneficial to establish genomic databank on gene-linked economic trait for conformation selection of tall pig breeds.
