| 摘要: |
| 科威418是作者通过特殊工艺研制而成的牛羊高蛋白复合添加剂，其中含有尿素、营养保护剂、酶及多种微量元素等。体外试验表明，以豆饼、尿素及科威418作为氮素饲料时，培养3h的培养液中NH3N浓度依次为14.5,25.7及22.3mg·(100mL)-1 (P<0.01);知,培养12h的NH3N浓度依次为7.3,11.4及13.3mg·(100mL)-1(P<0.05);真蛋白氮浓度依次为38.6.29.8及35.4mg·(100mL)-1(P<0.05),基质风干物消化率依次为54.97%,61.44%及64.91%(P<0.01)。 |

| Abstract: |
| Kewei-418 was a compound feed additive with high protein contents developed by the authors with special technology for cattle/sheep/goats,which contains
urea,nutritive preservative,enzymes,trace elements and carrier.When soybean meal,
urea or Kewei-418 was sole protein feed in the iso-nitrogen culture media,the contents
of ammonia nitrogen of formentation liquid in in vitro system were 14.5.28.7 and 22.3
mg·(100mL)-1 at the 3rd hour (P<0.01),and 7.3:11.4 and 13.3mg·(100mL)-1 at
the 12 th hour (P<0.05),and the true protein nitrogen contents of fermentation liquid
at the 12th hour were 38.6,29.8 and 35.4mg·(100mL)-1media were 54.97,61.44
and 64.91% (P<0.01),respeetively. |
