Abstract

Providing standard feed to support and improve the growth, productivity, health, and digestibility of livestock still requires feed additives, one of which is the natural feed additive spirulina flour. Spirulina flour was one of the natural feed additives chosen because it contained bioactive compounds, had no side effects on livestock, and substitute for antibiotics for livestock, so it could increase the growth, productivity, health, and digestibility of Peking ducks. The aim of this study was to analyze the effect of spirulina flour feed additive on Peking duck liver histomorphometry. This research used a Completely Randomized Design (CRD) with 5 types of spirulina flour concentration treatments (0%, 2.5%, 5%, 7.5%, and 10%) and 5 replications including 5 ducks in each replication. The treatment groups included P0, P1, P2, P3, and P4. Measurement variables included liver weight, hepatosomatic index, hepatocyte and central vein diameter, and sinusoid width. The data obtained were analyzed by the Analysis of Variance (ANOVA) test with a confidence level of 95%. The results showed that the addition of spirulina flour as a feed additive had no effect on liver weight, hepatosomatic index, hepatocyte diameter, central vein diameter, and sinusoid width. The conclusion of this research was that added spirulina flour (Spirulina sp.) feed additive potentially maintained the histomorphometry of the Peking duck liver organ.

Abstract

Diabetes mellitus (DM) is a degenerative disease that can lead to complications such as testicular atrophy. As DM requires lifelong treatment, natural and safe therapeutic alternatives are needed. Durian peel, as a natural material, has potential. This study investigated the effects of ethanol extract of durian peel (EEDP) on testicular histology in diabetic rats. A total of 25 male Sprague-Dawley rats, aged 2 months and weight ±200 g, were randomly assigned to five groups: healthy (K0), diabetic (K1), and diabetic+EEDP at doses of 500 (K2), 750 (K3), and 1,000 mg/kgBW (K4), given orally for 28 days. After treatment, the rats were euthanized, and their testes were removed, weighed, and examined using hematoxylin-eosin staining. Observed variables included testis weight, seminiferous tubule diameter, epithelial thickness, and spermatogenesis stages. Statistical analysis ANOVA (α=0,05) showed significant improvements (p < 0,05) in the EEDP-treated groups. It is concluded that EEDP at doses of 500-1,000 mg/kgBW improved testicular structure in diabetic rats.. The novelty of this study lies in the utilization of durian peel ethanol extract at varying doses of 500–1,000 mg/kgBW as a natural therapy to improve testicular histological damage caused by diabetes. This study serves as a basis for the development of herbal antidiabetic drugs with protective effects on the reproductive system. The findings are expected to contribute to biomedical science and provide opportunities for utilizing durian peel waste as a value-added material for public health.
