    ABSTRACT: Identification of genetic polymorphisms in the genes related to plumage color and elucidation of their associations with plumage phenotypes are important for the selection of desirable plumage colors. The aim of this study is to identify candidate genetic polymorphisms conferring white plumage color to select ducks with desirable plumage colors. Single nucleotide polymorphism (SNPs) in 4 candidate genes, namely the Agouti signaling protein gene (ASIP), Dopachrome tautomerase gene (DCT), Melanocortin 1 receptor gene (MC1R), and Microphthalmia-associated transcription factor gene (MITF), were investigated in forty birds, of which 20 were colored Korean native ducks and 20 were white-colored commercial ducks. Twenty-one primer pairs were designed to amplify entire exons along with partial introns of the 4 genes, and the PCR products were sequenced. A total of 83 polymorphisms were identified in these genes. We identified 8 and 36 SNPs in the ASIP and MITF genes, respectively. Thirty polymorphisms, comprising of 4 non-synonymous SNPs, were identified in the DCT gene. Two non-synonymous SNPs were identified in the MC1R gene. Two genetic variations [(c.726C>T and g.10585-88→AATC (4-bp indel)] in the DCT gene revealed significant associations with the 2 different colored breeds (P<0.001). The results of this study, after further verifications of the candidate SNPs, can be helpful for the selection of Korean native ducks with desirable plumage colors.

    ABSTRACT: The melanocortin-4 receptor (MC4R) gene is known to encode a membrane-bound receptor protein and is a member of the melanocortin receptor family of genes. In mammals, these genes are involved in energy homeostasis and in regulating feeding behavior and body weight. The objective of the present study was to examine if there were any associations between variations in the MC4R gene with meat quality traits in a commercial pig population in Korea. Among the total of 593 commercial pigs, sire information was retrieved from 232 pigs. These animals were successfully genotyped for the c.892A>G (p. Asp298Asn) single nucleotide polymorphism (SNP) by using ThqI PCR-RFLP methods. Association analyses between this SNP and meat quality traits were performed using a general linear model (GLM) including sire effect. This SNP was significantly associated with backfat thickness (P<0.05), marbling (P<0.01). Interestingly, this SNP marker was also associated with volatile basic nitrogen after 14 days of storage (P<0.05). To our knowledge, it is the first results observed for the MC4R genotypes with volatile basic nitrogen after 14 days of storage in the commercial pig population. Therefore, these results suggest that the MC4R gene can be targeted in marker-assisted breeding for selecting pigs with good meat quality.

    ABSTRACT: Optimal drying condition of brown rice was discussed for the low-moisture-content storage. A 100 g of brown rice samples with 15.5% moisture content wet basis (m.c.) was dried to 10.0% m.c. at 40, 50, 60, and 70℃ by thin-layer drying. The germination rate of the brown rice dried at 70℃ decreased, and drying operation did not affect the germination rate of the rice dried at 40-60℃. In addition, we discussed changes in cracking rate of brown rice after drying. Regardless of drying temperature, the cracking rate was less than 1% soon after drying. The cracking rate, however, changed with the passage of time, and depends on drying temperature; the rice dried at 30℃ has less than 1% of cracking rate after 72 hours, the cracking rate of the rice dried at 50 and 60℃ increased until after 48 hours, and that of the rice dried at 70℃ continued to increase for 72 hours. Finally, the Effect of drying condition on cracking rate was researched by drying samples at a combination of 30, 40, 50℃ and 5-10, 15-20, 25-30% of relative humidity (RH). From the results, it was suggested that drying temperature more affected the cracking rate than relative humidity in drying brown rice with 15.5% m.c. This suggestion was confirmed by multiple linear regression analysis. The optimal condition for drying brown rice from 15 to 10% m.c. was 40℃ and 5-20% RH from the viewing point of keeping rice quality and decreasing drying time.
