However, there is little metabolic profile data available about Korean Hanwoo cows. Therefore, this study aimed to determine the reference intervals of metabolic profile for Korean Hanwoo cows. Methods： Healthy animals （2,205） were selected and divided into early （day 1 to 95）, middle （day 96 to 190） and late （day 191 to 285） period according to their gestating period. Metabolic profile including total protein （TP）, albumin （AIb）, urea （UREA）, glucose （Glu）, total cholesterol （T-Cho）, long-chain fatty acid （LCFA）, aspartate aminotransferase （AST）, gamma-glutamyl transpeptidase （GGT）, creatinine （Crea）, calcium （Ca）, inorganic phosphorous （iP） and magnesium （Mg） were analyzed using a TBA-4OFR automatic biochemical analyzer. The data of Korean Hanwoo cows were then compared to those of the Japanese Wagyu cows. Results： Most of the data of the Korean Hanwoo cows were relatively higher than those of Japanese Wagyu cows, with the exception of Glu and GGT. This may indicate that the nutritional level of feed for the Korean Hanwoo cows was higher than that of the Japanese Wagyu cows because of the different feeding system. In particular, relatively higher levels of UREA and LCFA were observed in the Korean Hanwoo cows, and this may also contribute to the low reproduction efficiency. Conclusions： These findings may provide some theoretical basis for understanding the reproductive and feeding situation of Korean Hanwoo cows.展开更多

Characteristics of each cow were analyzed using ultrasound evaluation and trace of reproductive potential. A comparison of live carcass traits classified by parity was analyzed in all characteristics. The results of the comparison showed all characteristic increased rapidly after the 2nd parity, and decreased after the 4th parity （P 〈 0.01）. The result of comparison classified by the group showed a tendency, whereas Back Fat Thickness Ultrasound （BFTU） and P8 Fat Thickness Ultrasound （P8-FTU） were significant （P 〈 0.01） thinnest in Pedigree group and using a lot of reproduction in advanced group. Also, we made comparisons of the cow＇s calves on the carcass traits among the group. High quality calves of the pedigree group showed 30.77%. These are the highest carcass traits in meat quality grade above 1＋ and yield grade above A. Frequency of fertilization failure per rump fat thickness showed a significantly （P 〈 0.0｜） higher difference. The average frequency of fertilization failure demonstrated 1.11 times of experimental Hanwoo cows. In the analysis, frequency of fertilization failure appeared 0.9 times at rump fat thickness below 5 mm. However, it is higher than average above 5 mm. The result of the study will be used to improve cows, select optimum semen, as well as contribute to the improvement of farms income.展开更多
