  • Recently, the consumption of duck meat has been gradually increased in Korea. However, most of the duck breeds in Korea were imported from overseas. Based on the large demands for the breeding stocks of native ducks, a new project for the commercial use of the Korean native ducks has been launched. For the initial investigation of the relationships between Korean native duck (KND) with other duck breeds, the sequences from D-loop control region in mitochondrial DNA (mtDNA) was used. The results from phylogenetic analysis indicated that both KND and White Commercial Duck (WCD) breeds were classified well with wild duck breeds. However, mallard duck was not discriminated well with KND. The haplotype analysis indicated that KND and WCD have eight different haplotypes with eleven SNPs. Three haplotypes (haplotype 1, 3, 4) were shared both in KND and WCD. On the other hand, haplotype 1 was appeared only KND and haplotype 5, 6, 7, 8 were identified only in WCD population. With further verifications, the results presented here can be used for the conservation and commercialization of the Korean native ducks.

  • This work was carried out to improve the performance and the carcass yield of Korea native duck (KND) according to crossbreeding KND and broiler duck (BD). Two hundred forty out of crossbred ducks were divided into 4 strains and selected as 120 ducks separated by sex, respectively. Crossbred ducks were native ducks (female)${\times}$native ducks (male), native ducks (female)${\times}$broiler ducks (male), broiler ducks (female)${\times}$native ducks (male), and broiler ducks (female)${\times}$broiler ducks(male) as A, B, C and D, respectively. Broiler duck diet was fed as experimental diet for 0~3 weeks (CP 22.0%, ME 2,900 kcal/kg) and 3~8 weeks (CP 18.0%, ME 3,000 kcal/kg). Body weight of male was high compared to female, and that of B and C was high compared to A and low compared to D at 3 and 8 week (P<0.05). Body weight gain of male was high compared to female at 3~8 weeks and 0~8 weeks, and it was shown as D>C>B>A on body weight gain (P<0.05). In case of feed intake, there was no difference between male and female, and B and C were high compared to A and low compared to D (P<0.05). Male feed requirement was high at 3~8 weeks, and there was significant difference between A and B, C and between B and D. Carcass yield of 4 strains was shown as 70.1%, 70.8%, 73.1% and 71.2%, respectively. Finally, Crossbreeding of KND and BD may improve the performance and the carcass yield of KND.

  • This work was carried out to investigate on the retail cut yield and the meat quality of crossbred ducks. A total of 360 pullets that were produced from 4 mating methods used in this work. Four mating method were A) native ducks (female) $\times$ native ducks (male), B) meat-type ducks (female) $\times$ native ducks (male), C) native ducks (female) $\times$ meat-type ducks (male), and D) meat-type ducks (female) $\times$ meat-type ducks (male). Ducks were bred at the flat house, and selected nine ducks with similar weights from each treatment at the certain weeks (A, B, C 8 weeks; D 6 weeks). Selected ducks were slaughtered, calculated the retail cut yield(wing, back, neck, breast, leg), analyzed the physico-chemical compositions, and tested the sensory evaluation. Wing and neck meat ratios of D treatment were lowest (P<0.05), and breast meat ratio of B treatment was high (P<0.05) compared to other treatments. pH of duck meat was no difference among treatments, fat and protein contents of B treatment was highest, and collagen contents of D treatment was highest among all treatments. Meat color and physical compositions was no difference among treatments. Juiciness of D treatment meats was highest, and there was no difference between B and D treatments. Finally, mating method of native duck and meat-type duck affected on the retail cut yield, but did not improve on the physico-chemical compositions and sensory evaluation.

  • 본 시험은 냉동 및 해동 방식에 따른 토종오리 고기의 이화학적 특성을 조사하기 위해 수행하였다. 처리구는 8주령 오리육을 대조구(Control)로 하고 처리구는 냉동방식 2가지(급냉, $-50^{\circ}C$; 완냉, $-20^{\circ}C$)과 해동방식 2가지(완해동, $4^{\circ}C$ 냉장해동; 급해동, $13^{\circ}C$ 유수해동;의 $2{\times}2$ 복합요인으로 하여 총 5처리구, 처리구당 3반복, 반복당 3점(2수/점)으로 나누었다. 공시재료는 각 처리구에서 발생된 8주령 토종오리 수컷을 처리구당 18수씩 선별하여 도압하고 1개월간 저장 후 분석에 이용하였다. 명도는 완냉시키거나 완해동할 때에 대조구와 유의적인 차이가 있었으나(P<0.05), 적색도와 황색도는 처리구간 유의차가 없었다. 가열감량과 보수력은 급냉시키거나 급해동시킬 때 대조구에 비해 유의적으로 높게 나타났으나(P<0.05), 전단력은 대조구에 비해 낮게 나타났다(P<0.05). 가열감량, 전단력, 보수력은 냉동 처리구 사이에서는 유의적인 차이를 보이지 않았으나, 가열감량은 급해동과 완해동 사이에 유의차가 나타났다(P<0.05). 수분, 지방, 단백질, 조회분의 함량은 냉동 처리구와 대조구 사이에서 유의차가 없었으나, 수분함량은 급해동 처리구에서 완해동 처리구에 비해 유의적으로 높게 나타났으며(P<0.05), 단백질 함량은 완해동 처리구에서 대조구에 비해 높게 나타났으나(P<0.05) 해동 처리구간에는 유의적인 차이가 없었다. 지방과 단백질 함량은 해동 처리구 사이에서 유의적인 차이를 보이지 않았다. 결론적으로, 본 시험에서는 냉동과 해동 방식에 따른 오리고기의 특징을 보여주고 있으며, 이런 결과들은 토종오리 산업과 오리육 생산 산업에 큰 도움이 될 것이라 사료된다.

  • The objective of present research is to evaluate the effect of breed and sex on flavor-related compounds of duck meat in Korea. Breast meat of each different breed [Korean native duck (KND) and commercial duck, Cherry Valley (CD)] and sex (male and female) were analyzed for chemical composition, nucleotide, fatty acid composition, and free amino acid. In comparison within the different breed and sex, CD and female duck were higher in moisture composition compared to KND and male duck. The meat from female duck had higher inosine monophosphate (IMP) contents while the meat from KND had higher inosine contents (P<0.05). Mostly, male duck had higher contents of free amino acid, including alanine, aspartic acid, glycine, histidine, leucine, serine, valine, glutamic acid and cysteine (P<0.05), even though no significance in the sum of taste-related free amino acid was observed with respect to breed and sex. From the results, it was found that breed has no significant impact while sex has influenced the flavor-related compounds, especially, IMP and most of the free amino acids. In order to get breed-specific advantages, KND should be developed based on flavor aspect and further studies using KND with known genetic confirmation should be conducted for the extrinsic and intrinsic flavor influencing factors.
