Abstract

The study was conducted to investigate the effect of dietary energy and protein levels on milk production in Saanen (Capra hircus) dairy goats fed the diets with the different ratio of forage and concentrate. Four lactating goats in mid lactation ($57.5{\pm}10.8\;kg$ BW) were used in a $4{\times}4$ Latin square with 21-d periods. Animals were randomly allocated to one of the four groups; 10.59 MJ ME/kg and 11.90% CP (TJ), 10.14 MJ ME/kg and 12.73% CP (T2), 9.45 MJ ME/kg and 15.19% CP (T3), 8.75 MJ ME/kg and 16.60% CP DM (T4). Also ratio of forage to concentrate was 49: 51 (Tl), 59: 41 (T2), 74: 26 (T3) and 90: 10 (T4). Intakes of forage and concentrate were linearly increased (p<0.05) with their increasing energy levels in the diets. No significant differences were found in total dry matter intake and body weight between treatments. Milk yield in T3 was the highest among treatments (p<0.05). Relative to other treatments, T4 significantly (p

본 시험은 산양유 생산을 위해 유기사료를 이용하여 유산양의 적정 에너지 및 단백질 공급 수준과 조농비율을 결정하기 위하여 비유중기 Saanen종 유산양 4두($57.5{\pm}10.8\;kg$ BW)를 이용하여 $4{\times}4$ 라틴방각법으로 실시하였다. 대사에너지 공급수준과 단백질 공급수준을 10.59 (T1), 10.14 (T2), 9.45 (T3) 및 8.75 (T4) MJ/kg과 11.90 (T1), 12.73 (T2), 15.19 (T3) 및 16.60% (T4)로 달리하였으며, 조농비율은 49:51 (T1), 59:41 (T2), 74:26 (T3) 및 90:10 (T4)의 네 처리구로 나누었다. 사료 섭취량 및 체중은 모든 처리구 사이의 유의한 차이가 없었다. 유량은 T3구에서 가장 높았으며, T2 및 T4구와 비교하여 유의하게 높게 나타났다 (p<0.05). 유지방함량과 생산량은 T4구에서 다른 처리구와 비교하여 가장 낮았다 (p<0.05). 유단백질과 유당 생산량은 T1 (61.29 및 70.95 g/일)과 T3 (60.52 및 75.82 g/일)구에서 T2 (50.49 및 59.64 g/일)와 T4 (52.49 및 59.82 g/일)구와 비교하여 유의하게 높게 나타났다. 결과적으로 유산양의 유생산성을 극대화시키기 위해서 에너지 공급수준은 최소 9 MJ/kg 이상과 단백질 공급수준은 최소 15% 이상을 공급해 주어야할 것으로 기대된다.
