A Study Of Exploiting Banana Stems And Leaves Into The Feed Of Ruminant

Bananas are extensively planted in Guangxi province. There leaves banana stems and leaves after the fruit harvested whose yield is almost as many as that of the bananas. And banana stems and leaves are the better feed resource to ruminants. At present, they haven't been widely used for ruminants, because they contain higher tannin. I nth is study, forage was ass i gned to s i x treatments: no add i t i ve (contro I), 1% urea (I), 2% molasses (II), 2% lime (III), 0.5% EB (IV) and 0. 2% tannase crude extract (V). They were ensi led for 60d. The nutritive value after ensiling banana stems and leaves was evaluated, which was based on the results of the si I ages character i st i cs, the content of crude prote i n, Ac i d Detergent Fibre(ADF)and tannin and palatability experiment in lactating cows. The aim of this study was to exploiting the banana stems and leaves into the feed of ruminant. The result showed that the si I age qua Iity of molasses group was better than that of any other groups, with has turquoise, strong acidic and sweet-smelling, the tendentious texture, not adhibit ing hands, and pH3. 92. The content of the crude protein (CP) in every additive groups was all increased, 1.77%(I), 0. 13%(II),0. 160/o(III), 0.33% (IV), and 0.22% (V), respectiveIy,compared with the control. Among these groups, the urea group was significantly higher than any other groups in crude protein content (p<0.05). These additives resulted in a decreased ADF by 3. 37% ( I ), 4. 58% (II), 7. 25% (III), 2. 38% (IV), 0.69% (V), respectively, compared with the control . In ADF content, there was significant difference among these groups only except for tannase group and the control, as we I I as urea group and EB group. In tannin content, additive groups were reduced by 0. 10mg/g ( I ), 0. 37% (II), 0. 15% (IV), and 0. 19mg/g (V), respectively, compared with the control, except that I ime group was 0. 02mg/g higher than control group. The tannin content in molasses group was significantly lower than lime group and control group (p<0. 05). The find ings indicated that a I I these groups improved the qua I ity of the si I age to some extent, that urea group increased obviously the content of crude protein, I ime group decreased the content of ADF, and that molasses group significantly decreased the content of tannin and enhanced the palatability of the silage.
