| 摘 要： | 利用蜡熟期全株玉米青贮和完熟期去穗玉米秸秆青贮,分别饲喂肉牛,进行育肥增重试验。30头供试肉牛平均分为两组,通过对比试验,其结果为:喂全株玉米青贮组头均日增重1891g,喂去穗秸秆青贮组头均日增重 997 g,经分析差异极显著(P<0.01)。将两组所耗精料、粗料及所增毛重按当时市场价分析,60 d试验结束,喂全株青贮组和去穗青贮组,平均每头获利分别为291.90元和97.02元;每千克增重费用分别为4.69元和5.28元。用全株玉米青贮饲喂肉牛效果优于去穗秸秆青贮,且适口性强,消化利用率高,增重效果明显,在平原农区应大力推广。

| Abstract: | Finishing trials were carried out with 30 beef cattle fed with silage of whole wax-ripening corn stalk with ear and full-ripening corn stalk without ear. Results showed average daily gains of two groups were 1891g and 997 g, respectively, the first was significantly higher than that of the second group (P<0. 01). Analysis on the present prices of concentrate and forage and gross weight gains of cattle showed average profits and costs per kilogram of weight gain in groups two groups were ?91. 9 and ?97. 02, ?4. 69 and ?5. 28,respectively. It was showed that whole corn silage with ear was better than corn silage without ear and for its higher feed efficiency, which could be widely extended agrarian areas. |
