まとめ
トウモロコシのシラージは発酵係数 (FC) と消化能力が最も高い. トウモロコシが手に入らない場合は,BRS Zuriと比較して優れている発酵のためにBRS Capiaçuのような多年草が推奨されます.
科学分野:
- 動物と栄養科学
- 飼料の品質と保存
- 農業科学
背景:
- シラージの生産は,特に熱帯地域では,家畜の飼料に不可欠です.
- 動物の栄養を最適化するために,熱帯の飼料の品質を評価することが不可欠です.
- 発酵係数 (FC) と分解性 (degradability) は,シロージの栄養価の重要な指標である.
研究 の 目的:
- 熱帯の飼料の発酵率 (FC) を決定する.
- シラージの発酵性プロファイル,化学組成,およびin vitro分解性を分析する.
- 選定された多年生熱帯草と全植物トウモロコシのシロージの質を比較する.
主な方法:
- 5つの処理 (飼料種) と4つの繰り返しのランダム化ブロック設計が採用されました.
- 飼料種には,全植物トウモロコシ (Zea mays),Cenchrus purpureus cv が含まれていた. BRS カピアス,ウロクロア・ブリザンタ BRS Piatã, U. decumbens cv. バイト・アルバイト・アルバイト バジリスクとメガティルス・マクシマス BRS チューリ
- 測定された主なパラメータは,FC,化学組成,pH,アンモニア含量,in vitro乾物消化性 (IVDMD),および中性洗剤繊維 (NDF) の分数であった.
主要な成果:
- 全植物のトウモロコシは最も高いFC (P < 0.001) を示し,次にBRS Capiaçu; BRS Piatã,Basilisk,そしてBRS Zuriは最も低いFCを示した.
- トウモロコシのシロージは,最も効果的なDM消化率 (P < 0. 001) を有していたが,BRS Capiaçuのシロージは,より高い消化不可能なNDF分子を有していた (P = 0. 009).
- トウモロコシとBRS Capiaçuのシラージは,BRS Zuriのシラージと比較して,pHとアンモニア含有量が低い (P < 0.001).
結論:
- フルプラントのトウモロコシは,FCと消化性の点でシロージの生産に優れている.
- トウモロコシが実現できない場合は,BRS Capiaçu,BRS Piatã,Basiliskがインシリングのための多年草として推奨されます.
- BRS Zuriは,他の評価された熱帯の飼料に比べて,シロージに適していません.
