The Use of Cassava Peel as a Source of Energy for Substituting Rice Bran in Ration Containing Gliricidia maculata Leaves in Dairy Cows

Abstract

The objectives of this research are (1) to obtain an alternative feed; (2) to determine the best level of using cassava peel in ruminant ration to substitute rice bran in term of nutrients intake, digestibility of nutrients, and milk yield; (3) to obtain ration formulation for lactating dairy cows using cassava peel. The cattle used in this study were 4 Frisian Holstein dairy cows aged 5 years with a body weight of 400 kg. This research was conducted using the Latin Square Design 4x4 consisted of 4 treatments (rations). The ration was prepared with a ratio of forage and concentrate 55:45. The treatments were the use of cassava peel as follows: T1=0% Cassava peel; T2=3% Cassava peel; T3=6%Cassava peel; T4=9% Cassava peel. The result showed that there is no significantly different (P>0.05) on nutrient intake, nutrient digestibility, and milk yield. It can be concluded that the cassava peel can be used in dairy cattle ration up to 9% with the value of dry matter intake 13.29 kg day-, organic matter intake 12.59 kgday-, crude protein intake 1.97 kg day-, digestibility of dry matter, organic matter and crude protein were 71.75%, 73.62%, and 73.67%, respectively. Milk yield was 8.64 kg.
