Silage Preservation to Detoxify Hagonoy (Chromolaena odorata)
Devil weed (Chromolaena odorata), locally known as ‘hagonoy’ is a problem weed infesting pasture areas and rangelands in the Philippines as well as in other tropical countries but it can be used as a palatable ruminant feed. ‘Cogon’ (Imperata cylindrica), can be ensiled with hagonoy at different proportions (i.e. ‘cogon’ + 5% ‘hagonoy’, ‘cogon’ + 20% ‘hagonoy’, ‘cogon’ + 35% ‘hagonoy’ and ‘cogon’ + 50% ‘hagonoy’). Molasses added to silage treatments provide readily fermentable carbohydrates to improve ensileability and acceptability of the silage to animals. Physical and chemical evaluations showed that cogon-hagonoy silages were well fermented with adequate moisture content (<70%), pH of < 4.0 with the absence of clostridial fermentation. Hagonoy added to cogon at 50% gives the highest value of crude protein, ash and in vitro digestibility.
