초록
현재 한우에서는 영양대사물질 수준에 대한 연구가 미흡한 수준이다. 따라서 본 연구는 한우 번식우에 있어서 임신과 비임신 상태에 있어서혈액내 주요 영양대사물질을 분석하였다. 한우 번식우 54두를 방목을 하였을 경우에는 혈액내 주요대사물질 6개 항목(AST, ALT, Cholesterol, Glucose, BUN, NEFA)을 분석하였다. 사육방법과 관련된 NEFA수준 조사에서 방목우 임신우 평균은 221±105 uEq/L이고, 사사 사육 임신우평균 240±121 uEq/L로 나타났으나 유의적인 차이는 없었다. 콜레스테롤 수준은 사사 사육시 임신우 113.33±17.03 mg/dL이었고, 비임신우는137.25±21.77 mg/dL로 비임신우에서 유의적으로(p<0.05) 높은 결과를 보였다. 사사 사육시 NEFA 수준(임신우 204±119 uEq/L과 비임신우286±215 uEq/L)도 콜레스테롤 수준과 동일한 경향을 보였다. 분만 전ㆍ후 AST 수치는 각각 105.53±24 IU/L와 81.59±12.55 IU/L으로 분석되어분만 후에서 유의적으로(p<0.05) 감소한 결과를 보였다. NEFA 수준에서는 분만 전 122±52 uEq/L, 분만 후 497±239 uEq/L 로서 분만 후에서유의적으로(p<0.05) 높은 결과를 보였다. 이러한 NEFA 수준의 증가는 분만 후 번식우가 필요로 하는 영양대사물질이 증가하였기 때문인 것으로사료된다. 이러한 결과를 종합하면 한우 번식우의 적정한 영양수준 관리는 생산성을 향상 시킬 수 있을 것으로 사료되며 한우 번식우에 대한영양수준 연구는 추가적으로 연구가 이루어져야 할 것으로 사료된다.
Abstract
The purpose of this study was to investigate the appropriate level of NEFA related to pregnancy by analyzing NEFA among the nutritional metabolites in Hanwoo cows. The results of the basic data for the management of breeding specifications were investigated according to the grazing results of appropriate blood nutrition metabolites in Hanwoo cows. The survey items were AST, ALT, Cholesterol, Glucose, BUN, and NEFA. Among these six items, the NEFA level survey, which is related to breeding, showed that the average of pregnant individuals in grazing cows was 221±105 uEq/L and the non-pregnant individuals were 240±121 uEq/L, However, there was no significant difference. The cholesterol of pregnant individuals in non-grazing was 113.33±17.03 mg/dL and the non-pregnant cow was 137.25±21.77 mg/dL, which was significantly higher in non-pregnant cows. Likewise, NEFA levels (pregnant cow 204±119 uEq/L and non-pregnant cow 286±215 uEq/L) were the same. The MPT results of prenatal and postpartum AST 105.53±24 IU/L and 81.59±12.55 IU/L were significantly decreased postpartum in pregnant individuals. NEFA level, postpartum group was significantly (p<0.05) higher (497 uEq/L) than before partum (122 uEq/L). In conclusion, the NEFA level related to breeding without any difference between grazing and non grazing showed significantly higher results than non-pregnant cows in pregnancy, and the NEFA level before and after delivery showed a significant increase after delivery. It is thought that maintaining proper nutrition levels in Hanwoo cows can improve productivity through the improvement of the breeding rate of cows, and various studies should be carried out to improve breeding efficiency through the iimprovement of nutrition levels.
