1. Dry matter intake was significantly increased above the 30% red clover plant composition (p<0.05) as compared with 100% orchardgrass plant composition. However, there was a significant positive correlation (p<0.05) between the content of CP and dry mat

산양의 발정주기의 생리와 조절에 관한 최근 연구 보고들과 한국 재래산양의 대한 이들 연구 결과를 모아 고찰하였다. 온대지역에서 산양의 번식계절은 분명하나 한국재래산양의 경우는 비번식계절이 비교적 짧거나 계절적 무발정율이 낮은 편이며, 비번식계절에는 기능적 황체가 유지되지 않는다. 한국재래산양의 발정주기와 발정지속기간은 타품종과 비슷하며, 발정지속기간의 반복력은 매우 낮으며, 발정주기중의 progesterone과 estradiol-17의 소장을 규명하였다

The aim of the present study was to determine the effect of dietary cultured wild ginseng root (CWGR) supplementation on goat milk composition and ginsenoside profiles. Sixteen Saanen dairy goats were allocated to two balanced groups based on lactation period, body weight (38.6 ± 3.2 kg), and dairy milk yield (2.85 ± 1.2 kg), and were kept in separate pens. Goats were fed a total mixed ration (TMR) feed (2.3 kg/d, dry matter basis) and 1.5 g of CWGR powder was supplemented in the experimental diet. The total feeding period was 3 weeks, and milk and blood samples were collected on the last three days of the experimental period. There was no effect of CWGR on daily milk yield and milk composition (fat, protein, lactose, and solid-not-fat). However, the CWGR-treatment group had significantly higher plasma IgG and protein contents than the control group (P < 0.05). Significant amounts of ginsenosides were observed in the milk of the CWGR-treatment group, whereas ginsenosides were not detected in the milk of the control group. In conclusion, dietary CWGR was a useful regimen to produce functional goat milk enriched in ginsenosides.
