那西肽
發布時間: 2015/8/17 17:21:11

1.那西肽是一種含硫多肽類動物專用抗生素,屬于環保型飼料添加劑
  Nosiheptide is a kind of special sulfur-polypeptide antibiotic for animal, environmentally feed additives.
?明顯促進畜禽生長,改善飼料利用率
  Significantly promote the growth of livestock and poultry, improve the feed efficiency.
?不產生耐藥性,與其他抗生素無交叉耐藥性
  No resistance, no cross resistance with other antibiotics.
?在動物腸道內不被吸收,無藥物殘留
  Not to be absorbed in animal intestinal tract,no drug residue.
?對人、畜安全,對環境環保
  It’s safe to human and livestock, environmental protection to the environment.
2.那西肽是20世紀60年代有法國科學家從阿根廷土壤中分離出來的一種抗生素,是一優良的非吸收型飼料添加劑,添加在飼料中不影響適口性,對豬、雞、鴨、蝦和淡水魚等水產動物都有促生長增重作用,提高飼料轉化率的效果。法國和日本已正式將它作為飼料添加劑投放到市場,也是我國近年批準使用的獸用抗生素,作為飼料添加劑在畜牧業屆得到了越來越多的廣泛使用。
  In the 1960s,Nosiheptide is separated from the Argentina soil by French scientists, is a good type of non-absorptive feed additives.It doesn’t affect the palatability of feed, it promotes the growth and weight of pig、chicken、duck、shrimp、freshwater fish and other aquatic animals, it also improves the feed efficiency. France and Japan have officially put it to the market as feed additives, it is the antibiotic approved by Agriculture Ministry of China in recent years,it’s used more and more times in animal husbandry.
3.理化性質
  那西肽為黃綠色物質,呈粉末狀或細針狀結晶,熔點為310-320℃(伴隨分解)。那西肽可溶于氯仿、二甲基酰胺、二甲基亞砜,微溶于甲醇、乙醇、乙酸乙酯和苯,不溶于水和石油醚。
Physicochemical property:
Yellow-green material, powder or fine needle crystal,its melting point is 310-320℃(with decomposition ).It’s soluble in chloroform, dimethylformamide, dimethyl sulfoxide,lightly soluble in carbinol, ethanol, acetidin and benzene,not soluble in water and petroleum ether.
4.作用機制
那西肽對革蘭氏陽性菌具有較高的活性,尤其是葡萄球菌。同時對一些革蘭氏陰性菌也有效,如出血敗血性巴斯德氏菌和卡他奈必瑟氏菌。作用機制是阻礙細菌蛋白質合成,在低濃度時抑菌作用,在高濃度時呈殺菌作用。由于那西肽阻抑了腸道內有害菌的繁殖,使腸道管壁吸收機能正常,因為促進了動物生長,提高了飼料利用率,不易產生耐藥性,與其他抗生素無交叉耐藥性。毒性小,對人、畜安全。由于該抗生素能明顯促進動物生長,而且在動物體內無殘留,是優良的非吸收型飼料添加劑。
Mechanism of action:
Nosiheptide has strong activity on against G- bacterium and G+ bacterium,especially staphylococcus. The mechanism of action is restraining the protein synthesis. Control the bacteria in the low concentration,kill the bacteria in the high concentration. Nosiheptide resist the breeding of harmful bacterium in the intestinal tract, so it promotes the growth of livestock and poultry, improves the feed efficiency. No resistance, no cross resistance with other antibiotics. Small toxicity, safe to human and livestock. No drug residue, is a good type of non-absorptive feed additives.
5.耐藥性   Resistance
a)用葡萄球菌和鏈球菌對那西肽作恒量傳代試驗,結果顯示,這兩株菌對那西肽沒有耐藥性。
The test to Nosiheptide using staphylococcus and streptococcus shows,these two strains has no resistance.
b)用對各種抗生素耐藥的金黃色葡萄球菌做那西肽的敏感性試驗,結果顯示,那西肽和其他抗生素之間沒有交叉影響,這說明那西肽不會引起交叉耐藥性。
The Sensitivity test to Nosiheptide using golden staphylococcus shows, Nosiheptide has no cross resistance with other antibiotics. It shows that Nosiheptide won't cause cross resistance.
6.對環境的影響
被排出的那西肽在豬和雞的糞中的半衰期分別為一個月和20天,將這些糞作為配料施于植物方面,發現那西肽在植物組織內無殘留,且對高等植物除草劑活性以及殺蟲劑的活性都沒有抑制作用。對部分藻類及部分土壤細菌有抑制作用。對活性污泥微生物沒有阻礙活性,而且沒有副作用。因此那西肽對于環境的影響可以認為是極小的。
The impact on the environment:
The half-life of discharged Nosiheptide in dejecta of pig and chicken is one month and 20 days, applied these dejecta as ingredients to plants,found that Nosiheptide has no drug residues in plant, and no inhibitory action on higher plan herbicide activity and insecticide activity.It has inhibitory action on part of some algae and soil bacteria. No hindered activity on the active sludge microbial, and no side effects. Therefore the impact on the environment of Nosiheptide is minuteness.
7.殘留性
?給雞飼喂那西肽0-250mg/kg,連續8周,給豬飼喂那西肽0-500mg/kg,連續90天,在給藥中間以及停止給藥后的0-7天屠宰,檢測結果顯示,肝、肌肉、脾、心臟等的殘留量均小于0.025mg/kg(臨界值以下)。
Residual property:
Feed the chicken 0-250mg/kg Nosiheptide for 8 weeks, 
feed the pig 0-500mg/kg Nosiheptide for 90days, slaughter them in medicine time or after the treatment of 0-7 days,the result shows, the residual quantity of liver、 muscle、spleen、heart is lower than 0.025mg/kg.( below the critical value ).
?用C14標記的那西肽進行了跟蹤給藥試驗,發現大部分那西肽排入糞便之中,這說明其在腸道內發揮了作用,但沒被分解和吸收,排泄于動物糞便中,即在動物的臟器和組織內無殘留。
Do test using C14 Nosiheptide,the test shows,most of Nosiheptide are discharged to dejecta,this proves that Nosiheptide plays a role in the intestinal but not broken down and absorbed, no drug residue in animal visceras.
