홍삼 부산물의 급여는 거세돈 등심육의 일반성분에 아무런 영향을 나타내지 않았다. 홍삼 부산물의 급여는 거세돈 등심육의 육질 특성에 유의적인 차이를 나타내지 않았으나, pH와 보수력은 T4 처리구에서 다소 높았고, 육즙 손실은 T3 처리구에서 다소 낮았다. 홍삼 부산물의 급여는 등심육의 주관적 판정 항목에서 대조구와 비교하여 T3와 T4처리구에서 높은 수치를 나타내어 바람직한 경향이었으며, 육색에서는 a값(적색도)의 경우 대조구와 비교하여 T3와 T5 처리구에서 유의적으로 높은 수치를 나타내어 적색의 바람직한 외관을 나타냈다. 관능 특성에서는 대조구와 비교하여 T2와 T4 처리구에서 다즙성과 전체 기호도가 다소 높은 경향이었고, 풍미의 경우 T2와 T4 처리구에서 대조구보다 유의적으로 높은 수치를 나타내어 바람직한 경향을 나타냈다. 이상의 결과에서 홍삼 부산물의 급여는 거세돈 등심육의 육질 특성을 향상시켜 브랜드육으로서의 가능성이 높은 것으로 사료되었다.

3원교잡종의 지육지방축척과 육질에 대한 종료종모돈(두록종:D, 버크셔종:B, 매산돈:M)의 영향을 보기 위해, 랜드레이스종과 대요크셔종의 F1(LW) 종빈돈에 D, B 또는 M종의 3품종의 종모돈을 교배시켜 얻은 3원교 잡종(LWD, LWB, LWM)에 대해서 지육의 지방 축적량, 로스육의 물리적 특성과 화학적 조성 또는 근육섬유의 특성, 근육과 피하지방의 지방산 조성을 비교 검토했다. 시험돈은 3원교잡종 각각에 대해서 거세돈 수컷과 암컷을 각각 6두씩, 합계 36두를 공시했다. 단사(單飼), 무제한 급여 하에서 체중이 30kg에서 105kg가 될 때까지 사육했다. 도살한 돼지의 지육우반환(枝肉右半丸)의 제5-6, 8-9, 11-12, 13-14 흉추(胸椎) 간, 제16흉추-제1요추(腰推) 또는 최후요추-제1선추(仙推)간의 횡단면지방의 면적비율은 어떠한 부분에도 LMW이 LWD, LWB보다 통계적으로 유의가 많았다. 로스육의 물리적 특성치인 Tenderness는 $LWM961.3Kgw/cm^2)$ of $LWD(84.13KgW/cm^2)$와 $LWD(87.22KgW/cm^2)$보다 유의적으로 부드럽고, Pliability는 역으로 LWM이 LWD, LWB보다 유의 있게 낮았다. 또 로스육의 근육내 지방함량은 $LWM(3.23\%)$이 $LWD(2.32\%)$과 $LWB(2.35\%)$보다 유의성 있게 많았고, 가열 손실율(加熱損失率)은 LWM이 LWD, LWB보다 유의성 있게 높았다. 근섬유경(筋纖維經)은 LWD가 LWB, LWM보다 큰 경향으로 인정되어 지고, 근속(筋束)의 횡단면적은 LWD가 LWB 또는 LWM보다 유의 있게 조밀했다. LWM은 근육 내 지방산인 오레인산이 LWD, LWB보다 훨씬 높았고, 불포화 지방산의 비율이 높았다. 이상의 결과 종료종모돈이 3원교잡종의 육질에 영향을 미친다는 것이 명확하게 되었다.

This study was carried out to investigate carcass grade of pigs according to gender, feed intake, backfat thickness, carcass weight, etc. Data from a total of 26,983 heads in 5 farms were collected. The results obtained were as follows; The difference was significantly found in carcass quality grade between barrows and gilts (p<0.001). The meat grade $1^+$ was high in gilts, but meat grade 1 was high in barrows, respectively. The carcass weight of 85.8 kg was lightly shown significantly (p<0.05) in group I taken little quantity of feed consumption. However, that of 89.5 kg was heavily shown in group IV taken plenty of feed consumption. Meat grade 2 was significantly (p<0.001) high ratio in group of backfat thickness with less than 15 mm (67.5%). However, the ratio for the grade 1 was high in group of 15~19 mm. The ratio for the meat grade 2 was highly shown in group of carcass weight with more than 85 kg (54.3%). On the other hand, that of grade 1 was highly shown in group of 78~84 kg. In conclusion, pigs for marketing to enhance high quality have been appropriately raised with the optimum system in consideration of feed intake, carcass weight, backfat thickness, etc.

The Jeju native pigs of 168 heads (116 barrows and 52 gilts) were examined to investigate the carcass characteristics related to gender, meat quality grades and yield grades. The averages of carcass characteristics for Jeju native pigs were 72.94 kg for carcass weight, 20.98 mm for backfat thickness, 38.14 for Hunter L*, 4.68 for a*, 6.04 for b*, 5.61 for pH, 3.61 for visual plate meat color, 3.36 for marbling scores, 1.83 for meat quality grades and 2.08 for yield grades, respectively. The carcass weight of gilts was significantly higher than that of barrows (p<0.05). There were no significant differences between barrows and gilts in carcass percent, backfat thickness, and meat color. The pH of barrows was significantly higher than that of gilts (p<0.05). The differences between gender groups were significantly noticed in carcass quality grades, and yield grades (p<0.05). The carcass weight, carcass percent, backfat thickness, and marbling scores for pigs with high grades(1 and 2 grades) were significantly higher than those for pigs with low grades (p<0.05). However, there was no significant difference among 4 carcass grades. The carcass weight, carcass percent, backfat thickness, pH, and meat color for carcass with high yield grades were significantly higher than those for carcass with low grades (p<0.05). The meat colors for Hunter L*, a* and b* were not significantly shown in carcass yield grades.

The feeding group, composed of weaning pigs fed 3 mL of glucosamine derivatives, was compared for the carcass and quality characteristics with the unfeeding control group for 25∼70 days since they were born. The results were as follows; There were no significant differences in carcass weight and back-fat thickness between the feeding group and the unfeeding group although the feeding group had low ranges of standard error when compared to the control. Feeding group had higher incidence frequencies of A grade (42.7%) than the control (29.2%). The feeding group and unfeeding group had no significant differences in meat color, cooking loss, WBS, pH, WHC and purge loss. Results from this study showed that feeding GD had effect on the decrease the market weight and production of consist carcass weight, however, the feeding GD had no effect on pork quality during rearing times after weaning.
