| 摘 要： | 研究了精饲料和精青配合饲料饲养下育肥猪排污量和主要污染物含量的差异.结果表明,与饲喂精饲料相比,饲喂精青配合饲料的生猪产粪量降低18.97%,产尿量降低38.56%.精饲料饲养50d后,生猪体质量仅比精青配合饲料饲养平均增加1.5kg,采用精青配合饲料饲养的生猪体质量每增加lkg饲料成本投入比精饲料饲养减少21.68%.精青配合饲料喂养生猪不仅可减少污染物的排放量,还可节约饲料投入成本,提高养猪效益.

| Abstract: | Study was performed on effect of type of feed on excretion of fattening pigs and major pollutants it contains.Results show that compared with pigs fed with concentrate feed,pigs fed with concentrate-green combined feed excreted 18.97% less dung,and 38.56% less urine.After 50 d of feeding,pigs fed with concentrate feed gained on average only 1.5 kg more in weight than those fed with concentrate-green feed.The use of concentrate-green feed,however,saved cost of feeding by 21.68% per kilogram weight gain.It is... |
