Effect of banana stems (Musa sapientum L) fermented with molasses, biochar and with or without vinasse on weight growth of muscovy duck (Cairina moschata)
The experiment was carried out on 72 healthy muscovy ducks starting at 28 days old to assess the effect of banana stems (Musa sapientum L) fermented with molasses, biochar and with or without vinasse on weight growth of muscovy duck (Cairina moschata). Four treatments and three replications made up a completely randomized design (CRD) of the experiment. Each batch is an experimental unit, each experimental unit consists of 6 muscovy ducks.
Four treatments correspond to 4 different diets: Treatment 1: 30% mixed banana with molasses + 70% mixed feed; Treatment 2: 30% mixed banana with molasses and 1% Biochar + 70% mixed feed; Treatment 3: 30% mixed bananas fermented with molasses + 55% mixed feed +15% vinasse; Treatment 4: 30% mixed banana with molasses and 1% Biochar + 55% mixed feed + 15% vinasse.
Experimental results: Treatment 4 had the lowest feed conversion ratio (5.87), followed by Treatment 3 (6.85), Treatment 1(6.99), and the highest belonged to Treatment 2 (7.12). However, these variations were not statistically significant (P>0.05). In 4 experimental treatments, Treatment 3: 30% mixed banana fermented with molasses + 55% mixed feed +15% vinasse was more effective than other treatments in terms of weight gain and feed consumption.
It was concluded that vinasse and banana stems can be used for silage with molasses as a good feeding source for muscovy ducks. The addition of Biochar or the absence of Biochar in the diet did not significantly affect the weight gain of ducks at the end of the experiment.
