Performance and Economic Efficiency of Young Anglo-Nubian Goat Fed Different Protein and Energy

Abstract

The aimed of this study was to assess the economic ef ciency as well as the performance of young Anglo-Nubian goat fed different protein and energy on its concentrate. Twelve young female Anglo-Nubian goats weighing on average (± SE), 35.03 ± 3.91 kg, were divided into three groups (R1, R2 and R3), and received different levels of crude protein (CP) and energy (as total digestible nutrient-TDN) in concentrate diets for 12 weeks trial. R1=16% CP, 62%TDN; R2= 15% CP, 65%TDN and R3= 14% CP, 68%TDN. All animal also offered King- grass ad-libitum and 1kg of mixed forages. Feed intakes measured daily but live weights weekly. The experiment conducted in a completely randomized design. Input and output analysis applied in order to assess the economic ef ciency. The result showed that The concentrate diets had signi cant effects on CP and TDN intakes (p<0.05) but had not signi cantly (p>0.05) in uenced the DMI, ADG and FCR. The DMIs were 1338, 1358 and 1369 g/d for R1, R2 and R3, respectively. The CP and TDN intakes for R1, R2 and R3 were 230 and 961 g/d, 228 and 1000 g/d, 223 and 1036 g/d. The ADGs for R1, R2 and R3 were 150.9, 134.5 and 112.3 g/d with the FCR values were 8.87, 10.09 and 12.20, respectively. Economic analysis from the use of higher protein concentrate was having most pro table with an average of income over feed cost (IOFC) of IDR 2000/head/day. Therefore, it can be concluded that the concentrate (R1) can be used for growing young Anglo- Nubian goats.
