Substitution of Bread Waste in Rations on Digestibility of Dry Matter and Organic Matter in Ettawa Crossbreed Goats

Abstract Feed is the highest operational cost in raising livestock, the price of concentrate which is increasing to Rp. 4.800/kg (0.29 USD/kg) adds to the burden of farmers. Therefore, farmers are looking for alternative feed ingredients that can replace concentrates as a source of energy, one of which is by utilizing food waste in the bread waste. Bread waste is a by-product of the bread industry that has expired and is not suitable for human consumption and has been withdrawn from the market. The purpose of this study is to investigate how the consumption and digestibility of Dry Matter (DM), Organic Matter (OM) and Crude Protein (CP) are affected when bread waste is substituted in the diets of Ettawa Crossbreed goats. Fifteen second-lactation Ettawa Crossbreed goats were employed in this investigation. Three treatments, each with five replicates, were employed in the completely randomized design (CRD) undirectional pattern study. P1 = Corn silages 20% + Concentrates 64% + 16% bread waste; P2 = Corn silages 20% + Concentrates 56% + bread trash 24%; and P3 = Corn silages 20% + 48% concentrates + 32% bread waste were the ration treatments that were administered. The ration treatment comprised a 20:80 composition of forages and concentrates. The consumption and digestibility of DM, OM and CP were among the variables examined in this investigation. According to the study, the consumption and digestibility of DM, OM and CP were not significantly impacted by the usage of bread waste (P>0.05). The conclusion of this research are bread waste can be substituted for concentrates in rations up to a 32% level in terms
