本試驗之目的在探討胎次與泌乳期對羊乳品質之影響。本試驗共使用母羊23頭,自母羊分娩後至泌乳期4個月期間,每週分別記錄個別母羊的乳量,並採集上、下午的分房乳樣一次,以分析乳樣的乳清乳酸去氫活性、體細胞數、導電度、pH值、乳脂肪、乳蛋白質、乳糖與乳無脂固形物含量。試驗結果顯示,(1)乳量:泌乳母羊之每日平均乳量為2.928±0.052 kg,其中以第3週至第8週之乳量較其他週次為高,惟各週間之差異不顯著。另外,上午之乳量顯著較下午多44%,而且隨母羊胎次之增加,乳量呈極顯著增加(P<0.001)。(2)乳清乳酸去氫活性:平均為78.29±1.95 U/l,其中以母羊在分娩後第1週之羊乳乳清乳酸去氫活性顯著較其他各週為高(P<0.05),而其後則逐漸降低,至第8週以後則維持於穩定之低值。另外,羊乳之乳清乳酸去氫活性以下午顯著較上午為高(P<0.05),並隨胎次之增加而降低,且各胎次間亦呈極顯著差異(P<0.001)。 (3)羊乳之體細胞數:平均為43.7±3.7 ×104 cell/ml,其中以泌乳期之第1週及第15週以後之羊乳體細胞數較高,而其他時間則較低。另外,羊乳之體細胞數以下午顯著較上午為高(P<0.05),且隨胎次增加而呈增加之趨勢。 (4)羊乳之導電度:平均為6.75±0.03 mS/cm,其中以第1週之羊乳導電度顯著較其他週次為低(P<0.05)。此外,羊乳之導電度以上午顯著較下午為高(P<0.05),且以第1胎顯著較第2胎以上為低(P<0.05),並隨胎次之增加而呈增加之趨勢。 (5)羊乳之pH值:平均為6.60±0.01,並以下午之乳樣顯著較上午為高(P<0.05),而第1週之羊乳pH值顯著較其他週次為低(P<0.05)。另外,第1胎之羊乳pH值較第3胎及以上為低。(6)羊乳之脂肪含量:平均含量為2.70±0.06%,並以下午之乳樣顯著較上午為高(P<0.05),且以第1胎之羊乳脂肪含量顯著較其他胎次為高(P<0.05)。另外,泌乳第1週之羊乳脂肪含量較其他週次為高,但各週次間差異並不顯著。(7)羊乳之蛋白質含量:平均為3.08±0.03%,且上、下午之乳樣間無顯著差異,而以第1胎之羊乳蛋白質含量顯著較其他胎次為高(P<0.05)。另外,泌乳第1週之羊乳蛋白質含量顯著較其他週次為高(P<0.05),但在第3週時其含量明顯下降,而其後則維持穩定之數值。(8)羊乳之乳糖含量:平均為4.43±0.02%,而上、下午乳樣間並無顯著差異,且以第1胎之羊乳乳糖含量顯著較其他胎次為高(P<0.05)。另外,泌乳第1週之羊乳乳糖含量顯著較其他週次為高(P<0.05),而其後則隨泌乳週數之增加而降低。(9)羊乳之無脂固形物含量:平均為8.09±0.05%,而上、下午之乳樣間並無顯著差異,並以第1胎之羊乳無脂固形物含量顯著較其他胎次為高(P<0.05)。另外,泌乳第1週之羊乳無脂固形物含量顯著較其他各週為高(P<0.05),其後則隨泌乳週數之增加而呈下降趨勢。

The purpose of this study was to evaluate the effects of parity and lactation stage on the quality of goat milk. Milk samples of morning and evening were collected weekly. During the experimental period, milk yield was recorded weekly, lactate dehydrogenase(LDH) activities, somatic cell counts(SCC), electrical conductivities(EC) and pH of milk were analyzed weekly, and milk fat, protein, lactose and solid-not-fat(SNF) contents were analyzed biweekly. The result showed that (1)Milk yield: The average milk yield was 2.928 kg per day. Milk yield of the morning was 44% higher than those of the evening. Milk yield was significantly increased with parity number. Milk yield of 3rd to 8th week of lactating stage were higher than those of the other weeks. (2)LDH activity: The average milk serum LDH activity was 78.29±1.95 U/l. Milk serum LDH activities of the evening samples were significantly higher than those of the morning. Milk serum LDH activities were significantly declined with parity number. The LDH activities of first lactating week was significantly higher than those of the other weeks, and it declined at the 8th week, then there were no significant change. (3)SCC: The average milk SCC was 437±37 ×103 cell/ml. Milk SCC of the morning samples were significantly higher than those of the evening. Milk SCC were increased with parity number. Milk SCC of 1st, 15th and above weeks of lactating stage were higher than those of the other weeks. (4)EC: The average milk EC was 6.75±0.03 mS/cm. Milk EC of the morning samples were significantly higher than those of the evening. Milk EC of first parity were significantly higher than those of the other parities. Milk EC of first lactating week were significantly lower than those of the other weeks. (5)pH: The average milk pH was 6.60±0.01. Milk pH of the evening samples were significantly higher than those of the morning. The milk pH of first parity were lower than those of the third parity. Milk pH of 1st lactating week were significantly lower than those of the other weeks. (6)Fat content: The average milk fat content was 2.70±0.06%. Milk fat contents of evening samples were significantly higher than those of the morning. Milk fat contents of first parity was significantly higher than those of the other parities. Milk fat contents of 1st lactating week were significantly higher than those of the other weeks. (7)Protein content: The average milk protein content was 3.08±0.03%. There were no significantly differences between the milk protein contents of morning and evening samples. Milk protein contents of first parity was significantly higher than those of the other parities. Milk protein contents of 1st lactating week were significantly higher than those of the other weeks, then it declined and kept constant after the 3rd lactating week. (8)Lactose content: The average milk lactose content was 4.43±0.02%. There were no differences between the milk lactose contents of morning and evening samples. Milk lactose contents of the first parity were significantly higher than those of the other parities. Milk lactose contents of 1st lactating week was significantly higher than those of the other weeks, then it declined thereafter. (9)SNF content: The average milk SNF content was 8.09±0.05%. There were no differences between the milk SNF contents of morning and evening samples. Milk SNF contents of first parity were significantly higher than those of the other parities. Milk SNF contents of 1st lactating week were significantly higher than those of the other weeks, then it slightly declined thereafter.
