Dampak Penggantian Jagung Giling dengan Tepung Kulit Pisang Hasil Fermentasi dalam Pakan Konsentrat dan Imbuhan Zn Biokompleks terhadap Profil Darah Sapi Bali Jantan Penggemukan

This study aimed to analyze the impact of replacing milled corn with fermented banana peel flour (KPF) and Zn-biocomplex supplemented concentrate feed on the blood profile of fattening male Bali cattle. Twelve male Bali cattle aged 2–2.5 years, with a body weight range of 130.5–175.5 kg (coefficient of variation: 7.87%), were used in a completely randomized experimental design. The treatments were as follows: P0 (70% forage + 30% concentrate without KPF substitution), P1 (25% KPF substitution), P2 (50% KPF substitution), and P3 (75% KPF substitution). Results showed erythrocyte levels (10⁶/µl) of P0: 10.06 ± 0.48; P1: 10.37 ± 0.45; P2: 11.06 ± 0.06; P3: 10.26 ± 0.17. Leukocyte levels (10⁴/µl) were P0: 10.68 ± 0.61; P1: 11.56 ± 0.46; P2: 11.14 ± 1.08; P3: 10.75 ± 0.72. Hematocrit levels (%) were P0: 31 ± 2.40; P1: 33.36 ± 1.11; P2: 33.79 ± 1.32; P3: 32.26 ± 1.16. Analysis of variance (ANOVA) indicated no significant differences (P > 0.05) in erythrocyte, leukocyte, or hematocrit levels among treatments. In conclusion, substituting up to 75% of milled corn with KPF in the concentrate feed, combined with Zn-biocomplex supplementation, did not adversely affect the blood profile of fattening male Bali cattle. This suggests that fermented banana peel flour can serve as a viable alternative to corn in cattle feed formulations.
