1、29水產(chǎn)飼料加工工藝學(xué)二、水產(chǎn)飼料的種類(一)水產(chǎn)配合飼料水產(chǎn)配合飼料是水產(chǎn)全價(jià)配合飼料、水產(chǎn)添加劑預(yù)混合飼料、水產(chǎn)濃縮飼料和水產(chǎn)混合飼料的統(tǒng)稱。水產(chǎn)全價(jià)配合飼料按產(chǎn)品形態(tài)和制作方式又可分為:1.硬顆粒飼料2.擠壓顆粒飼料3.軟顆粒飼料4.微囊顆粒飼料5.粉末飼料6.其他形態(tài)飼料第一章水產(chǎn)配合飼料原料第一節(jié)原料的種類與特點(diǎn)一、飼料原料的分類(一)根據(jù)飼料來(lái)源分類1.植物性飼料:青綠飼料、粗飼料、谷類子實(shí)及加工副產(chǎn)品等。2.動(dòng)物性飼料:利用動(dòng)物性產(chǎn)品加工而成,奶粉、魚粉、蠶蛹、肉骨粉、羽毛粉等。3.微生物飼料:利用微生物包括酵母、霉菌、細(xì)菌及藻類等生產(chǎn)的飼料。4.礦物質(zhì)飼料:天然和工業(yè)生產(chǎn)的
2、礦物質(zhì),如石粉、食鹽、硫酸銅等。5.特種飼料:尿素、添加劑等。(二)國(guó)際飼料分類法-由美國(guó)科學(xué)家HarrisL.E.(1963)提出,目前已被世界許多國(guó)家接受。該法以各種飼料干物質(zhì)的主要營(yíng)養(yǎng)特性為基礎(chǔ),將飼料分為八類:1.青干草和粗飼料:粗纖維含量≥18%,青干草、秸稈、秕殼等。2.青飼料:天然含水量≥60%,牧草、蔬菜類、樹葉等。3.青貯飼料:用新鮮的天然植物性飼料調(diào)制而成的青貯飼料,包括水分含量在45%~55%的低水分青貯(半干青貯)料。rationalconcepttoallownetworkmoreinlinewiththeobjectivelawsofthefuturedevel
