南昌师范学校生物教师马希贤学习苏联先进科学经验,以鹅蛋蛋白替换鸡蛋蛋白进行“动物无性杂交”实验成功,这是我国教师克服困难进行创造性的教学的一个良好的范例.马希贤在去年12月30日用鹅蛋蛋白替换鸡蛋蛋白孵出了“杂交鸡”7只.这种“杂交鸡”劲长腹宽,脚粗?大,有些和鹅相似.这种鸡生活力很强,不怕寒冷,体重增加很快.到今年5月8日,拿同时孵出的一只“杂交鸡”和一只普通鸡比较,“杂交鸡”的体重是31两5钱,普通鸡只有24两.按“杂交鸡”现在生长的??和苏联科学家的实际成就来看,这种“杂交鸡”再生长半年以后,体重可能达到8市斤.马希贤这个实验的成功,使学生对于生物学教材中关于“杂交”和“改变胚胎生活条件可以引起生物变异”等部分有生动深刻的理解,并大大提高了学生学习科学的信心和兴趣.马希贤这个实验的成功,对在现有条件下改良 Ma Xixian, a teacher of biology at Nanchang Normal University, learned from the advanced scientific experience of the Soviet Union and succeeded in experimenting with the replacement of egg protein by goose protein in “animal ansexual hybridization.” This is a good example of our teachers’ creative teaching of overcoming difficulties. On the 30th with egg protein replacement egg protein hatched “hybrid chicken ” 7. This “hybrid chicken ” Jin long belly width, feet thick, some similar to goose .This chicken vitality Strong, not afraid of the cold, weight gain quickly .To May 8 this year, take the same time hatched a “hybrid chicken” and a normal chicken compared to “hybrid chicken” weight is 31 two 5 Money, ordinary chicken only 24. According to “hybrid chicken ” now growing ?? and the Soviet scientists the actual achievements of view, this “hybrid chicken ” growth after six months, the weight may reach 8 kg. The success of this experiment enables students to have a vivid and profound understanding of the biology textbooks such as “hybridization” and “changing the biological condition of the embryo’s living conditions” and greatly enhances students’ confidence and interest in learning science Ma Xixian The success of this experiment is to be improved under the current conditions
