摘 要:人工输精是蛋种鸡场的核心技术,尤其是现在养鸡业处于微利的时代,维持种蛋高受精率就显得非常重要。一般种鸡场受精率都能达到90%以上。但持续高指标却非常不易,其中有许多细微零星的因素影响着,使受精率常出现或高或低不稳定情况。所以维持高受精率,须从细微处着手,持之以恒。文章介绍了持续维持笼养蛋种鸡高受精率的技术措施。Srtificial insemination is the core technology of egg chicken farm, especially the chicken industry now are in small profit era, to maintain the high fertilization rate of caged egg chicken is very important. General chicken fertilization rate could reach more than 90%, but the continuous high index is very not easy, there are many small sporadic influencing factors, the fertilization rate often appear unstable situation. So to maintain the high fertility rate must start from scratch and keep persistent. This paper introduced the technical measures of continuous maintain the high fertilization rate of caged egg chicken.
