高压生物静电场对雏鸡增重的影响

为研究高压生物静电场对肉蛋两用雏鸡生长发育状况的影响,采用不同强度的高压静电场和不同作用时间处理雏鸡,结果表明:施加的电场场强相对低时(+21.4 kV/m),无论作用时间长短,均未见统计学差异(P＞0.05)；28日龄时,电场场强+35.7kV/m作用30 min/(次·日)较作用15 min/(次·日)的雏鸡体重增加显著(P＜0.01)；电场场强±28.6 kV/m,作用30 min/(次·日),负电场高于正电场的作用效果,平均体重增长率分别为59.59％和23.46％；而电场场强增到±71.4 kV/m,作用效果明显降低.结果显示,适宜的电场强度和作用时间有促进雏鸡体重增加的作用,在一定范围内的不同场强和不同作用时间对雏鸡体重增加的影响有所差异.

Effects of the high voltage biological electrostatic field on the weight increases of the chicks

To study the effect of the high voltage biological electrostatic field on the growth of the chicks,different electrical filed strengths and working times are applied to chicks.The results show that when the applied electric field strength is low(+21.4 kV/m),there is no statistical difference(P >0.05).In the 28th day,under the electrical field of +35.7 kV/m,the chicks'' weight increases are more significant when the applying time is 30 min/(T·d) compared with 15 min/(T·d) (P<0.01).Under the electrical field of ±28.6 kV/m and the applying time of 30 min/(T·d),the chicks weight increases achieved by the negative field are higher than those by the positive field and the average increase rates of the negative and positive field are 59.59% and 23.46% respectively.When the electrical field strengths increase to ±71.4 kV/m,the effect is decreased.The results show that the proper field strengths and working times can promote the chicks'' weight increases and different chicks'' weight increases are achieved by different electrostatic field strengths and working times within a certain range.
