【實(shí)用技術(shù)】燕麥飼料化加工利用

導(dǎo)讀：燕麥不僅是較好的飼草，而且其籽粒亦為能量飼料，燕麥籽粒作為飼料的優(yōu)點(diǎn)主要是蛋白質(zhì)、粗纖維、粗脂肪以及鈣和磷的含量在禾谷類作物中是比較高的。

　　【農(nóng)機(jī)網(wǎng) 科技創(chuàng)新】 燕麥在家畜飼養(yǎng)業(yè)上是高級(jí)飼草和飼料。燕麥作為飼草的種類有青飼料、干草(青干草)、青貯飼料、藁秕飼料。我國各地奶牛場多以燕麥作青飼料和青貯飼料。燕麥不僅是較好的飼草，而且其籽粒亦為能量飼料，燕麥籽粒作為飼料的優(yōu)點(diǎn)主要是蛋白質(zhì)、粗纖維、粗脂肪以及鈣和磷的含量在禾谷類作物中是比較高的。
 
　　一、調(diào)制干草
 
　　刈割后避免淋雨，在割茬上晾曬，減少與地面直接接觸。在燕麥含水量低于35%時(shí)，將燕麥摟集成草壟，待水分<20%時(shí)進(jìn)行打捆，用圓草捆機(jī)或者方草捆機(jī)進(jìn)行打捆，繩捆密度應(yīng)=150kg/m3，再將干草打捆運(yùn)至干草棚存放。存放條件應(yīng)通風(fēng)，避免雨淋。貯存燕麥干草水分含量臆14%，應(yīng)有芳香味、無異味；顏色呈綠色、淺綠色或者黃綠色；莖葉均勻一致，無霉變、無結(jié)塊現(xiàn)象。
 
　　二、青貯
 
　　普通青貯含水量65%-70%；半干青貯含水量45%-50%。切碎長度3-5cm左右。裝填青貯窖時(shí)，用大型機(jī)械進(jìn)行逐層壓實(shí)，壓窖密度為700kg/m3，為保證青貯料質(zhì)量，可噴灑青貯添加劑。采用黑白膜進(jìn)行嚴(yán)密封窖，最后用重物壓實(shí)，使青貯料在密封厭氧的環(huán)境下正常發(fā)酵。1個(gè)月之后可取用。如果進(jìn)行裹包青貯，需先進(jìn)行打捆，再采用拉伸膜進(jìn)行裹包，通常需要包裹5-6層，以保證嚴(yán)格密封發(fā)酵。
