摘　　要：为了研究杂交野猪的生长性能、繁育水平与养殖环境、运动量、饲料配制的关系,根据野猪生活习性,对杂交野猪放养区内生活环境进行模拟(包括野猪巢穴、生态环境、植被),使杂交野猪能够有更多的运动范围和获取野外食物的机会。结果表明,放养模式下的杂交野猪产仔率(P<0.05)、仔猪存活率(P<0.01)均高于圈养模式杂交野猪,但增重速度显著(P<0.05)低于圈养模式下饲养杂交野猪。由试验结果可以得出,圈养模式下杂交育肥野猪增重速度显著高于放养杂交野猪,饲养管理难度较低,适合集约化大规模饲养。This study aimed to investigate the relationship between growth performance,reproductive performance of hybrid wild boar and their rearing environment,movement intensity and feed preparation.With consideration of the habits of wild boar,the rearing environment in the stocking area,including wild boar nest,ecological environment and vegetation was simulated to provide a more extensive movement environment and more access to wild food.The results showed that the number of litter and survival piglets were found significantly higher in the free-ranging hybrid wild boars compared to the confined ones (P<0.05 or P<0.01),whereas the weight gain rate was observed significantly lower in free-ranging ones (P<0.05).It can be concluded that the weight gain rate of the fattening hybrid wild boar reared in confined condition is significantly higher than the ones reared in a free-ranging condition,and the feeding management in confined condition is less difficult.Accordingly,the hybrid wild boars were suitable for intensive large-scale breeding.
