摘要
液态发酵饲料是指固体饲料与水按照比例(1∶1.5~1∶4.0)混合,经过微生物发酵制成的适口性好、易消化、营养价值高的液体饲料。在现代集约化生猪养殖中,为提高母猪繁殖效率、降低生产成本,养殖场通常推行仔猪低日龄断奶技术。但早期断奶的仔猪由于面临消化道机能发育不全、饲料抗营养因子多等诸多应激因素,易患上断奶应激综合征,导致其采食量下降、生长缓慢、腹泻率升高,严重危害养殖场的经济效益。液态发酵饲料具有物理形态与母乳相似、饲料营养价值高等特点,能够改善仔猪肠道菌群,提高仔猪消化能力,在仔猪生产中具有广阔的应用前景。本文通过介绍液态发酵饲料的定义、特点、生产方式及对仔猪生产性能影响,以期为液态发酵饲料在仔猪生产中的合理应用提供理论依据。
Liquid fermented feed refers to the liquid feed with good palatability,easy digestion and high nutritional value,which is mixed with solid feed and water in proportion(1∶1.5-1∶4.0)and fermented by bacteria.In todays intensive pig breeding,in order to improve the reproduction efficiency of sows and reduce the production cost,farms usually implement the weaning technology of piglets at low age.However,early weaned piglets are susceptible to weaning stress syndrome due to digestive tract dysfunction,feed anti-nutrient factors and many other stress factors.This leads to decreased feed intake,slow growth,and increased diarrhea rate of the piglets,which seriously endan⁃gers the economic benefits of the farm.Liquid fermented feed has the characteristics of similar physical form to breast milk and high nutrition⁃al value of feed.It can improve the intestinal flora of piglets,enhance their digestive ability,and eventually has broad application prospects in the production of piglets.This paper introduces the definition of liquid fermented feed,its characteristics,its production methods and its effects on piglet performance,hopefully to provide theoretical basis for appropriate application of liquid fermented feed in piglet production.
