abomasum n.皺胃〔反芻動物的第四胃〕。

abominable
This experiment is to probe the factors , such as the effect of the kid ' s suckling , the butchering age and the ay of the abomasums treatment on the chymosin activity ; the activation of the prochymosin ; the purification and separation of chymosin and the characterization of chymosin and pepsin , using cuan zhong dairy kid ' s abomasums as material , which would provide the theoretic base for the exploitation of the kid chymosin and its application to the cheese production 本實驗以關中奶山羊皺胃為原料，對羔羊哺乳狀況、屠宰年齡、皺胃處理方式和不同提取方法對凝乳酶活性的影響，凝乳酶原的激活，凝乳酶純化與分離以及凝乳酶和胃蛋白酶特性進行了系統的研究，為羔羊凝乳酶開發以及在干酪生產中的應用提供理論基礎。
To clarify epidemiologic characteristic of abomasum diseases in dairy cow of daqing regions , 14210 dairy cows from zhaoyuan county , lindian county , dumeng county and honggang district of daqing were investigated to identify status of abomasitis , abomasum impaction , abomasum ulcer and abomasum displacement 摘要為了闡明奶牛真胃疾病在大慶周邊地區的流行病學特點，對肇源縣、林甸縣、杜蒙縣、大慶紅崗區等地的14210頭奶牛的四種真胃疾病（真可炎、真胃阻塞、真胃潰瘍和真胃變位）進行了調查。
The research on the condition of kid ' s suckling indicates that the highest milk - dotting activity ( 26108su / g ) was obtained for the whole suckling section , whereas proteolytic activity were no significant different between the whole suckling and random section ( p > 0 . 05 ) , but proteolytic activity ( 1925u / g ) was highest for the complete grass - feeding , which demonstrated suckling could stimulate the continuous secretion of chymosin in the abomasum 羔羊哺乳狀況研究表明，全哺乳組凝乳活性最高( 26108su g ) ，蛋白水解活性與隨機哺乳組無明顯差別( p 0 . 05 ) ，而全喂草料組蛋白水解活性最高( 1925u g ) ，這表明哺乳能夠刺激皺胃中凝乳酶的持續分泌。
The training course on livestock production diseases control is lectured mainly on biosecurity epidemic disease prevention and treatment of dairy cattle in livestock farms , fine quality dairy production , biosecurity measures for prevention of dairy udder diseases , mastitis , artificial insemination technology , abomasums displacement , caesarean section technology on the standing cows , dairy reproduction failures , etc . the training course is instructed by the combination of lectures with practices 動物疾病防治培訓班講授內容包括牧場奶牛的生物安全疫病防治優質牛奶生產預防奶牛乳房疾病的生物安全措施奶牛的乳房炎牛人工授精技術皺胃移位站立牛的剖腹產術奶牛繁殖障礙等。培訓班采用講授與實習相結合的方法。
With the increasing salt concentration , milk - clotting activity became higher and higher , then reached its peak , and then decreased gradually ; in the early extraction , the speed was quick , the milk - clotting activity was increased obviously . after it amounted to the maximum , the activity became steadily lower steadily ; the increasing temperature in extracting could improve the extraction activity , but too high temperature could result in the denaturation and inactivation ; the greater the ratio of abomasums and butter and was , the quicker speed was when the enzymes was drawn out , and after extracting for twice , most of the enzymes in the abomasums could be drawn out 隨著食鹽濃度增大，凝乳活性逐漸提高，當達到一定濃度后，凝乳活性又逐漸降低；在提取初期，提取速度較快，凝乳活性明顯提高，當提取達到最大值后，凝乳活性又逐漸下降；隨著提取溫度的升高，凝乳活性逐漸增大，但溫度過高時，會導致酶變性失活；隨著提取液與皺胃比例的增大，酶溶出速度加快，提取次數越多，皺胃中酶提取越充分，提取2次后，皺胃中絕大部分酶被提出。
Three steps were involved : ? ) estimation of the ileum volume of the animal using single compartment model . ? ) measurement of the flex of each compartment . ? ) determination of the amino acid content of chymus of abomasums and ileum , and calculation of the amino acid digestibility 試驗分為3步：一是測定回腸體積，二是測定各分域的流率，三是測定真胃和回腸食糜中氨基酸含量和計算小腸氨基酸消化率。
As the kid chymosin was extracted by the traditional way and the buffering way at different ph values , its activity mainly depended on the salt concentration , extraction time and temperature , the ratio of buffer and abomasums and extraction times 用傳統方法和不同ph緩沖液方法提取羔羊凝乳酶時，食鹽濃度、提取時間、提取溫度、提取液與皺胃比例、提取次數對凝乳活性有重要的影響。
It was very slow at 5 but become higher above 25 . the enzyme from abomasums used in cheese production was rough extracts containing chymosin and pepsin . through the gel filtration chromatography and ion exchange chromatogra 羔羊胃蛋白酶最適凝乳溫度為45 ’ c ；在45處理30inin ，酶活性開始下降， 60c處理30lliln ，酶活性完全喪失；酶的最適ph為1
The methods of the abomasums treatment suggested that the freezing method had least influence on milk - clotting activity , while the salting air - drying and natural air - drying went to another extreme 皺胃處理方式研究結果表明，冷凍處理對酶活性影響最小，鹽漬風干處理影響較大，自然風干處理酶活性損失最多。
The greatest activity could be obtained on the condition of 8 % salt concentration , 1 : 20 ratio of abomasums and butter , 30w / cm2 supersonic strength and 40min extraction time 在食鹽濃度8 ，皺胃與提取液比例1 ： 15時，用30w cm2超聲強度提取40min ，可獲得最大的凝乳活性。
Results showed that there were an obvious relationship among abomasum diseases with raising management , parities , milk yield , and onset period 調查結果表明：飼養管理、胎次、泌乳量、發病時期與真胃疾病有較大關系。
The process of amino acid digestion and absorption in goat digestive tract could he described as three compartments : abomasums , jejunum and ileum 將山羊消化道消化吸收氨基酸的過程分為3個分域：真胃、空腸和回腸。
Meanwhile , the partial proenzyme from the abomasums would be activated automatically by the latter two methods 同時還發現鹽漬風干處理和自然風干處理可使皺胃中一部分酶原自動激活。
While causes of abomasum diseases were analyzed , and strategies were suggested for prevention and cure 同時進行了病因分析和討論，并提出了建設性的防治對策。
