경남 김해시 생림면은 김해시의 명산인 무척산 아래 산수가 좋고 넓은 평야지대와 낙동강을 끼고 있는 전통적으로 한우 사육을 많이 하는 곳으로 유명하다. 부산경남은 한우 암소 거래가 많은 지역으로 현재도 도매시장 2곳에서 전국의 한우암소 시장을 주도하고 있는 곳으로 '생림 맛보우' 브랜드는 암소 브랜드로서 한우의 상징성을 가지고 있기도 하다. 이런 환경 속에서 조차환 대표는 1980년도에 현 부지인 경남 김해시 생림면 생철리에서 한우에 대한 애착과 사랑으로 한우사육을 시작하게 되었다.

The aim of this study was to evaluate combination of each of g.15532 C>A, g.17924 G>A SNP of FASN gene and beef quality grade of progeny in Hanwoo cow. In order to analyze the SNPs, genomic DNA was obtained from 270 Hanwoo cow and their progeny steer and g.15532 C>A and g.17924 G>A SNP was genotyped using single-based extension. Employing GLM as a statistical model. g.15532 C>A and g.17924 G>A SNP have a significant effect in Hanwoo steer but no significant effect in Hanwoo cow. Combination of each of g.15532 C>A, g.17924 G>A SNP and beef quality grade of progeny have a significant effect on marbling score in Hanwoo cow. Therefore, we suggest that g.15532 C>A and g.17924 G>A SNP contribute to genetic improvement on marbling score in Hanwoo cow.

This study was conducted to compare among bull, steer and heifer on growth performance, blood composition and carcass traits according to fattening phase in Hanwoo. 12 month of aged 4 bulls ($339.8{\pm}18.5kg$), 4 steers ($309.8{\pm}13.2kg$), and 3 heifers ($290.0{\pm}16.7kg$) were allocated in the stalls with individual feeding system during 20 months. Average daily gain was not different among the treatment groups during early fattening phase, but higher in the bulls and lower in the heifers after mid-fattening phase (p<0.05). The difference of body size by animal groups appeared from 24 month of age, and wither height and body length of Hanwoo heifer were the smallest (p<0.05) among treatment group. But wither height was not difference among treatment groups at 32 month of age. At 12 month of age, concentrations of serum cholesterol, triglyceride, glucose and total protein were higher in the heifers compared to other groups, and serum GPT (Glutamic pyruvic transaminase) was the highest (p<0.05) in the bulls, and serum GOT (Glutamic oxaloacetic transaminase) was the highest (p<0.05) at late fattening phase in the bulls. Meat yield index was similar between the bulls and the heifers, and the lowest (p<0.05) in the steers. Marbling score was significantly higher (p<0.05) in the steers and the heifers than in the bulls, and meat quality was the best in the steers among treatment groups. The results of this experiment might be used as a basal data on difference between gender in revision of Korean feeding standard for Hanwoo.

The purposes of the study were to examine the changes in carcass traits and surface meat color, and cortisol concentration by different altitudes and shipping distances for steer and cow. The experimental animals were shipped from Kangwondo, Kyunggido, Choongchungdo, and Kyungsangdo to Wonju LPC. The animals were examined for yield traits, quality traits, carcass grade, lightness, redness, yellowness, croma value, and cortisol concentration by different altitudes and shipping distances. The results showed that the carcass traits of steer like back fat thickness were not different by shipping distances of 100 km, 150 km, and 200 km. However, the fat thickness was higher in steers shipped from 250 km than 100 km, 150 km, and 200 km distance. Ribeye area was reduced significantly in 200 km and 250 km than 50 km. Yield index and yield grade were significantly low in 250 km than 50-200 km. However, meat color, fat color, texture, mature, and quality grade had no differences between shipping distances. Marbling score was not different in 50-200 km. However, the marbling score in 250 km was significantly lower than that of 50 km. In case of surface meat color by shipping distance, redness, yellowness, chroma value, and hue-angle were not different in shipping distance of 250 km. The lightness had similar result in 50-200 km. However, in case of 250 km the lightness was significantly low. The REA of cow carcass by shipping distance had no differences by shipping distance. The BET had similar results in 50-150 km. However, it had significantly thick in 200 km. The yield index and yield grade had no differences in 50-150 km. However, yield index and grade were significantly low in 200 km. The carcass trait of cow had no differences in all items by shipping distance. Although the carcass traits and the BET for steer by altitude had no differences between 100, 200, 300 and 500 m, but those were significantly thick in 400 m. And the yield index and the yield grade at altitude 400 m were lower than that of other altitudes. The quality traits and the quality grade had no differences between 100, 200, 300, 400, and 500 m altitudes. The yield traits, quality traits, yield grade, and quality grade had no significant differences by altitudes. In case of yield index of cow for 300 m was low than the cases of 100 m and 200 m. The surface meat color for steer and cow had no differences by altitudes. However, the lightness of cow had positive result in 100 m than 200 m and 300 m. In case of steer and cow the cortisol concentration by shipping distance was high as the shipping distances were longer. However, the cortisol concentrations of steer and cow by altitudes were decreased as the altitudes were increased. From the above results carcass traits and carcass grade were decreased and the cortisol concentration was increased as the altitudes were decreased for steer and cow.

This study was conducted to estimate genetic effects on economically important traits for genetic improvement in Hanwoo by using the real-time ultrasound measurements for longissimus dorsi muscle area (LMA), backfat thickness (BFT), and marbling score (Marb). The phenotypic data were obtained from 1,648 pedigreed cows, and general linear models were applied to test the effects of age, region, and body condition socre. The cows between 50 and 60 months of age had the greatest scores for LMA and BFT, and Marb (P<0.05). The cows in region C had the greatest scores for body condition socre, LMA and BFT, while in region J Marb was the lowest (P<0.05). There was positive relation with LMA, BFT, and Marb according to increase body condition socre. Heritabilities for LMA, BFT, and Marb were estimated as 0.136, 0.351, and 0.236, respectively. These results would provide primary information for the efficient implementation of genetic improvement schemes in Hanwoo.
