IMPROVEMENT OF CARBON-TO-NITROGEN (C/N) RATIO BY MAKING CASSAVA LEAF SILAGE AND ITS IMPLICATIONS IN DIGESTIBILITY IN GOAT

Abstract

The study has been conducted in the laboratory and goats pen of the Department of Animal Husbandry, State Polytechnic of Lampung, Indonesia. The study lasted for six months with complete randomized design four treatments and six replications.  A total of 24 local goats were used in this study. Treatment applied P1 = Silase with C / N ratio 17.88; P3 = Silage with C / N ratio 19.88; P2 = Silage with C / N ratio 18.88; and P4 = Silage with C / N ratio of 20.88. The observed variables of physical quality, nutrition, and nutrient apparent digestibility of cassava leaves silage. The result was material composition with C / N = 18,88 yielding physical characteristic of cassava leaves silage and the best nutrient apparent digestibility.
