Abstract

A study was conducted to evaluate the reserve extent, composition nutritive value of sugar cane leaves and top.  Sugar cane leaves were ensiled with molasses (3%, LM3), urea (4%, LM4) and 4% urea plus 3% molasses (LMU43).  Sugar cane top was treated with molasses (3%, NM3), urea (4%, NU4) and non-additive, both materials were done in triplicates.  The pH, dry matter (DM), crude prtoein (CP), neutral detergent fibre (NDF), acid detergent fibre (ADF) and in sacco dry matter degradation were determined at 0, 7, 7, 14, 30, 45, 60 days after ensiling. All treatments could be well stored after 60 ensiling days.  Protein content was of ensiled cane top increased while NDF and ADF was reduced and in sacco dry matter degradation was improved as compared to the fresh top at 48 and 72h, however those did not changed in sugar cane leaves.  Ensiling methods of sugar can top can be applied to store and improve nutritive value of sugar cane top as feed for cattle.

Tóm tắt

Thí nghiệm xác định khả năng dự trữ, hàm lượng dưỡng chất và mức phân giải vật chất khô bằng phương pháp in sacco được tiến hành trên lá mía và ngọn mía. Lá mía được ủ với 3% mật đường (LM3), 4% urea (LM4) và 4% urea 3% mật đường (LMU43) và ngọn mía ủ với 3% mật đường (NM3); 4% urea (NU4) và không có chất phụ gia, lặp lại 3 lần để đánh giá nồng độ pH, hàm lượng vật chất khô (DM), protein thô (CP), xơ trung tính (NDF), xơ acid (ADF)  và mức phân giải in sacco của vật chất khô qua các thời điểm 0, 7, 14, 30, 45, 60 ngày.
