乳牛繁殖性能的低下, 在各國都造成重大的損失; 在台灣, 每年可能因此
一原因損失兩億新台幣, 所以必須針對乳牛繁殖效能低下的原因加以研
究, 以期減少酪農的損失。本實驗的目的在於了解乳牛血清生化輪廓與飼
養管理、季節及繁殖性能之關係。本實驗分析自四個不同牧場採集不同季
節, 不同狀況之牛群, 共計414個樣品。其結果如下:一、懷孕牛群在鎂、
三甘油脂濃度及鹼磷鋂活性三項高於空胎牛群。產後40天內之空胎牛比空
胎90天以上者有較高的總蛋白與球蛋白濃度, 而膽固醇濃度則相反。正常
空胎牛較胎衣滯留者有較高之鈣、鎂及膽固醇濃度及鈣磷比, 而總膽紅素
濃度與鹼磷■活性則呈較低的情形。二、在季節方面則氣溫多變季節有最
高的總蛋白、尿素氮、鈣濃度及鈣磷比, 然而有最低的磷、三甘油脂濃
度; 冷季則有較高的三甘油脂濃度及鹼磷■活性; 而熱季則具有低的膽固
醇濃度, 而有最高總膽紅素濃度。三、不同的牧場間, 其乳牛血清生化輪
廓除了總膽紅素外, 其他血清生化物質的濃度均有顯著的差異存在。四、
在單一牧場, 繁殖性能改善的同時, 乳牛群的血清生化輪廓也會有改變。
綜合以上的結果, 各牧場間血清生化輪廓間多有差異; 且季節的影響除了
冷熱季的影響外, 在冷熱季轉換之間的氣溫多變季節也會對乳牛血清生化
輪廓有所影響; 繁殖性能改變時, 乳牛群的血清生化輪廓也會有所改善。

For realizing the relationship of diary cows' serum biochemical
profile with management, season, and reproductive performance
in Taiwan, 414 blood samples were collected from 4 different
farms. The samples were grouped by the farms, pregnancy,
seasons and the health condition of the cows. After analyzed
the serum samples with Hitachi 7050 automatic analyzer, the
results were analyzed by GLM procedure in SAS. The results were
shown as followed: 1)Pregnant cows had higher magnesium (Mg),
triglyceride (Tg) con- cerntration and alkaline phosphatase
(ALP) activity. The cowsorn in 40 days had higher total protein
(TP) and globumin (Glob) concentration and lower cholesterol
(Chol) concentration than the cows open more than 90 days.
Normal open cows have higher calcium (Ca), Mg and Chol
concentration and ratio of Ca and phosphate (P) and lower total
bilirubin (Tbil) concentration than the cows with retained
placenta. 2)In seasons, cold one had the highest Tg
concentration and ALP activity, hot one had lowest Chol
concentration and highest Tbil concentration, and the one with
fickle temperatures had highest TP, blood urea nitrogen (BUN)
and Ca concentration and ratio of Ca and P, and lowest P and Tg
concentration. 3)Expect of Tbil, there were noticable
differences in the serum biochemial profile between farms.
4)When the reproductive performance was improved, the serum
bio- chemical profile would change. According the results, the
different management would affect the serum biochemical
profile, and seasonal variations affected the concentration of
most serum constituents, and when the reproductive performance
was improved, the serum biochemicalrofile would change.
