Growth and Body Conditions Score of Thin-Tailed Sheep Supplemented with Citrus Peel Powder

Abstract

The research aims to examine the effect of citrus peel powder supplementation in feed on dry matter intake (DMI) and organic matter intake (OMI), dry matter (DMD) and organic matter digestibility (OMD), average daily gain (ADG) and body condition score (BCS) in sheep. The material used was 21 male thin-tailed sheep. The feed was 4% dry matter (DM) of body weight. The treatment consisted of 70% dried kale (Ipomoea spp), 30% concentrate, citrus peel powder 2.25% DM of basal feed, and citrus peel powder 4.5% of basal feed. The research design used was CRD with 3 treatments; each treatment was repeated 7 times. The treatment composition consisted of R0: dry kale 70% + 30% concentrate, R1: R0 Feed + citrus peel powder 2.25% basal feed, R2: R0 Feed + citrus peel powder 4.5% DM of basal feed. The results of this study showed a significant effect on DMI and OMI. The average DMI was R0 = 0.96 ± 0.07 kg/head/day, R1 = 1.05±0.08 kg/head/day, and R2 = 1.07±0.06 kg/head/ day. The average OMI obtained was R0 = 0.82 ± 0.06 kg/head/day, R1 = 1.90 ± 0.07 kg/head/day, R2 = 0.92±0.05 kg/head/ day. The average DMD obtained in treatments was R0 = 47.36±6%, R1 = 50.91±3%, and R2 = 62.32±6%. The results showed that supplementation with citrus peel powder had a very significant effect (P < 0.01) on ADG, namely R0 (89.65 ± 7.67 g), R1 (117.37 ± 10.25 g), and R2 (95.59 ± 8.05 g ), and had no significant effect P > 0.01 on BCS, namely the final BCS value at R0 (2.93 ± 0.19), R1 (2.93 ± 0.40) and R2 (2.82 ± 0.45). This research concludes that supplementing citrus peel powder at a 2.25% DM of basal feed significantly increases ADG, although it has not impacted the increasing BCS.
