The paper summarized the research for the effects of different grazing intensity on grazing behaviour , grazing grass species and productivity of sheep in recent years , the result showed that : there was a negative correlation between the live weight gain per sheep and the grazing intensity , but there was positive correlation between the live weight gain per hectare and the grazing intensity ; feeding intake of sheep decreased when the grazing intensity become heavier ; there was not significant effect of different grazing intensity on sheep breeding indexes ; as long with the grazing intensity become heavier , the feeding time of sheep increased while resting and idling time decreased , but feeding intake per hundred mouths and daily intake reduced while intake velocity increased ; sheep feeding adaptability is relative ; the light grazing was beneficial to promote mutton quality , but mutton quantity and gross economy benefit was low 摘要根据近几十年来放牧强度对绵羊放牧行为、采食植物组成和生产性能的影响进行了综述，得出以下结论：绵羊的个体增重与放牧率之间呈线性负相关，而公顷增重与放牧率之间呈正相关；绵羊的采食量随著放牧强度的加重而降低；放牧强度对母羊繁殖性能各指标影响差异不显著；随著放牧强度的加重，绵羊的采食时间增加，游走、反刍卧息时间减少；每百口采食量和日采食量减少，而采食速度增加；放牧绵羊的嗜食性是相对的；轻牧有利于提高肉的品质，但是产肉量低，总的经济效益不高。
I am a graduating student , i have the very strong self - confidence to own working ability , because in four years university life period ipositively used the idle time to accumulate the work experience foroneself , i had the enough desire to do better , the perseverance and the courage , these helped me to study on the practice path as well as to make up have been very many , i was willing to study , was willing to absorb , was willing to innovate , i should like to work as for me is that one nourishes the process growing up , in this process , i not only couldenrich i , also could diligently the unit which enriched me to holdpublic office 我是一个应届毕业生,我对自己的工作能力有很强的自信,因为在四年的大学生活期间我积极地利用了空闲时间为自己积累工作经验,我有足够的上进心,恒心和勇气,这些帮助了我在实习的道路上学习以及弥补了很多,我愿意学,愿意吸收,更愿意创新,我希望工作对于我来说是一个滋养成长的过程,在这个过程中,我不仅会丰富我自己,也会努力的丰富我所供职的单位
