This study aim was to evaluate the effect of different quality of dry complete feed and mineral (Zn-Se) supplementation on feed efficiency and income over feed cost of Ettawa crossbred goats. Sixteen weaned female goats aged 4-month-old were used in this study. The experiment was conducted in factorial 2x2 in a completely randomized design with 4 replications and 2 factors. The first factor was different levels of energy and protein in the diets: 14% CP + 63% TDN (T1); and 16% CP + 67% TDN (T2). The second factor was the Zn-Se supplementation (treatment and control). The concentration of Zn and Se in the supplement were 20 mg/kg and 0.2 mg/kg, respectively. Results showed that goats in T1 group lost the body weight (BW) by 11.07 g, whereas T2 group gained 10.48 g of BW within 6 weeks of experimental period. Supplementation of Zn-Se in the T2 diets prevented the BW lost and resulted in the highest BW gain (7.15 kg) within 14 weeks. Moreover, the T2 diets plus Zn-Se supplement also resulted in the highest feed efficiency (11.82%) as well as income over feed cost (IDR. 1,722 head/d). It is concluded that dry complete feed containing 16%CP and 67% TDN with Zn-Se supplementation (Zn 20 mg/kg + Se 0.2 mg/kg). It is recommended for female weaned-goat for the optimal growth and increase the income over feed cost. It is recommended for female kid goat at the growth phase.
