ABSTRACT
The inclusion of Papaya peel silage (PPS) is believed to improve the nutritional quality of dietary paddy straw silage (PSS) in sheep, showcasing its potential as an anthelmintic. A total of 18 naturally Strongylus-infected Priangan male lambs (initially with an average mean of 120 ± 31.8 eggs/g feces) were allocated using a completely randomized design. The objective was to compare three different as-fed doses of PPS inclusion, comprising 0% (PPS-0), 50% (PPS-50), and 75% (PPS-75) in a PSS-based diet. This comparison aimed to evaluate lamb performances both before (Phase 1, a 30-day trial) and after (Phase 2, a 42-day trial) an anthelmintic treatment, with each phase having six replicates (n = 6). Before the anthelmintic treatment, PPS inclusion showed no significant impact (P > 0.05) on the average daily gain (ADG, g/head/day) of the infected sheep. However, the total dry matter intake (DMI, g/head/day) was reduced (P < 0.001). The inclusion of dietary PPS-50 and PPS-75 effectively maintained fecal egg counts (FEC, eggs/g feces) of Strongylus sp. within the mild infection category. Additionally, fecal oocyte counts (FOC, eggs/g feces) of Coccidia were consistently lower for PPS-50 and PPS-75 compared to PPS-0. After the anthelmintic treatment, dietary PPS-75 significantly increased (P < 0.05) the ADG of sheep without adversely affecting the total DMI compared to the control group. This suggested that PPS had the potential to serve as both a feed supplement and an anthelmintic agent.
