摘要: 
本試驗之目的,在以新蛋白質系統觀念下,重新評估啤酒 粕
及豆腐渣兩種副產物單獨或混合以取代日糧部份精料時,對 泌乳牛隻
生產性能及瘤胃性狀之影響(副產物佔日糧乾基之10 %),藉以評估本
省副產物於乳牛之飼養價值,以提供酪農依副 產物之生產季節,來擬定
全年各個時期乳牛飼養計畫之參考。 選用32頭荷蘭牛逢機分成四組:
一、對照組 ;二、啤酒粕組; 三、豆腐渣組; 四、混合副產物組(啤
酒粕及豆腐渣各半)。試 驗日糧(乾基)均含35%玉米青貯料、20%苜蓿
乾草及45%精 料,並依NRC(1989)乳牛飼養標準配成等能量等蛋白質
之混合日 糧。經預備試驗一週後進行荷蘭牛飼養試驗八週。另外,以拉
丁方格設計將四頭裝置瘤胃廔管之荷蘭種乾乳牛,分配於四組 試驗飼
糧飼養之,每十日為一期,收集瘤胃液分析之。
試驗結果顯示乳量方面,豆腐渣組顯著高於其他三組 (P<0.05),
而啤酒粕組及混合副產物組又顯著高於對照組 (P<0.05)。採食量
方面對照組及啤酒粕組顯著高於豆腐渣組及 混合副產物組(P<0.05)。
在乳成分方面;乳脂肪、乳固形物、 乳蛋白質及乳糖含量(%)以對照
組、啤酒粕組及豆腐渣組顯著 高於混合副產物組(P<0.05)。而乳糖含
量(%)方面,豆腐渣組 又顯著高於啤酒粕組(P<0.05)。乳組成產量方
面,乳脂肪、乳 固形物、乳蛋白質及乳糖之產量(kg/d),豆腐渣組顯
著高於其 他三組(P<0.05),而餵飼混合副產物組牛隻之乳脂肪、乳固
形 物、蛋白質產量(kg/d)則顯著低於對照組及啤酒粕組
(P<0.05)。各日糧處理組間之瘤胃pH值,體重變化均無顯著差 異(
P>0.05)。

The aim of this study was to evaluate the effects of brewers
grains and bean curd pomance supplementation on the
performance of lactating cows and the characteristics of their
rumen (by-products accounting for 10% of TMR, DM basis), so
as to create a way to solve the problem of waste and pollution
from these by-products. Thirty-two Holstein lactating cows
were alloted radomly into four groups for treatment. The
treatments were control; brewers grains group; bean curd
pomance group and mixed by-products group(containing the same
amount of brewers grains and bean curd pomance), respectively.
The mixed rations of treatments were formulated to be iso-
energetic and iso-nitrogenous according to the nutrient
commendation of NRC(1989); and containing 35% corn silage、
20% alfalfa hay and 45% concentrate(DM basis). The
experimental period lasted for 8 weeks after a week of
acclaimation period. In addition, four dry Holstein cows fitted
with rumen cannula were used in a 4×4 Latin square with 10-d
periods for collecting rumen liquid samples for analysis.
Results showed that cows fed the bean curd pomance diet
produced significantly more milk than the others(P<0.05), and
cows fed the brewers grains and mixed by-products diet produced
significantly more milk than the control group(P<0.05). Both
the control and brewers grains groups took in more feed than
those in the bean curd pomance and mixed by-products
groups(P<0.05). The cows fed the mixed by-products diet produced
a significantly lower percentage of milk fat, total solids, milk
protein and milk lactose than the others(P<0.05). The milk
lactose percentage was significantly more high for cows fed the
bean curd pomance diet than those fed the brewers grains
diet(P<0.05). Regarding the amount of milk fat, total solids,
milk protein and milk lactose produced by cows; Cows fed a bean
curd pomance diet produced significantly more than the
others(P<0.05). Cows fed the mixed by-products diet produced
significantly lower amounts of milk fat, total solids and milk
protein than the control and brewers grains groups(P<0.05).
This diet did not significantly influence the body weight of
the cows or the ruminal pH values(P>0.05).
