　　【農機網 科技創新】 根據最新的氣象資料顯示，我市將迎入冬以來首場大范圍雨雪天氣，雪災會影響飼草料供應，飼草料是牲畜生長、發育、繁殖的必需物質，是冬季牲畜攝取營養的主要來源。為減少飼草料短缺對牲畜越冬造成影響，通遼市農牧業發展中心提醒廣大養殖戶要做好以下措施：
 
　　一、加固和修繕草棚等建筑設施‍
 
　　立即對干草棚、精料庫等建筑設施進行全面巡查，對存在隱患設施做好加固。雪后及時清理積雪，減少承重，防止發生坍塌造成損失。高危棚舍立即停止使用，盡快轉出草料。對嚴重積雪的屋頂，降雪后，及時組織人員進行清理。危險建筑區域設置臨時安全警示牌，同時通知相關人員。
 
　　二、做好飼草料儲備工作
 
　　雪后由于交通運輸不便，容易造成飼草料短缺和價格上漲，因此有組織、有規模、有計劃、有機制的粗飼料儲備能有效提高養殖場(戶)抵御自然災害的能力。根據畜群數量，暴雪嚴寒來臨前至少儲備一個月的飼料飼草，牛羊建議粗飼料以青貯為主，精飼料為玉米、豆粕為主，同時保證礦物質的添加。在飼草料儲備期間，要按照相關要求做好飼草料防水、防潮工作，以防發霉變質，對養殖場造成嚴重的經濟損失。
 
　　三、含水量較高的粗飼料的管理‍
 
　　在青貯玉米的制作過程中，采用夾層封窖技術，即青貯封窖時，先覆蓋一層青貯專用膜，中間夾層覆蓋草簾和毛氈，最后覆蓋一層塑料膜，杜絕或減少凍層，飼料取用要做到現取、現喂，以防結冰。
 
　　四、保障牲畜的營養需求和飼料質量
 
　　暴雪等極端天氣發生后，要及時調整日糧營養成分和采食量，適當增加精料供給量，同時增加礦物質和維生素的供給。寒冷季節牲畜易缺乏維生素A和維生素E，要重視這兩種維生素的添加，也可以通過補喂胡蘿卜和優質豆科牧草的方式來補充維生素的不足。采用TMR飼喂技術的養殖場，建議適當下調TMR日糧的含水量，并要做到少添、勤添，以防凍結，避免牲畜消化系統疾病及流產的發生。
