Abstract

Abstract. Sugiharto S, Atmaja BM, Widiastuti E, Hadiyanto H. 2021. Combined use of Spirulina platensis and Saccharomyces cerevisiae: Implication on growth, blood profile and intestinal morphology and bacteria of the Indonesian crossbred chickens. Biodiversitas 23: 160-165. The effects of Spirulina platensis and Saccharomyces cerevisiae on poultry growth and health have long been known. However, no research has been conducted on the combined use of these substances on the Indonesian crossbred chicken (ICC). This study evaluated how the combined use of S. platensis and S. cerevisiae affected ICC growth, blood profile, and intestinal ecology. A total of 288 ICC were separated into three groups, including CONT (basic diet), SP (diet with 0.3% S. platensis), and SPSC (diet with 0.3% S. platensis and 0.2% S. cerevisiae). Blood and intestinal content and segments were taken at week 9, while growth was determined weekly. SP had greater (p<0.05) body weight than CONT, but did not differ from SPSC. In SP, ileal coliform counts were lower (p=0.07) than in CONT. SPSC had lower (p=0.07) caecal Enterobacteriaceae counts than other groups. Blood profile, intestinal morphology, organ weight, and carcass traits did not vary (p>0.05) across the ICC. In conclusion, dietary supplementation of S. platensis improved growth performance and bacterial population of the ICC.

Dietary supplementation of Spirulina platensis and Saccharomyces cerevisiae on egg quality, physiological condition and ammonia emission of hens at the late laying period

“…In the current study, feeding S. cerevisiae and combining it with S. platensis reduced the population of LAB and LNE in the caecum digesta of laying hens. With regard particularly to S. cerevisiae, such probiotic yeast has reportedly been shown to possess antimicrobial characteristics, hence lowering the number of dangerous bacteria, such as LNE, in the intestine of (Sugiharto et al, 2022). Different from Erya et al (2020) showing no effect of S. cerevisiae on the caecal LAB population, results in this present study showed reduced caecal LAB counts due to S. cerevisiae treatment.…”

“…Overall, several parameters showed better results with single administration of S. platensis or S. cerevisiae, when compared to the combined administration of S. platensis and S. cerevisiae. This may be because the combination of S. platensis and S. cerevisiae does not always have a synergistic effect on poultry conditions (Sugiharto et al, 2022). The results of this study indicate that single administration of S. platensis or S. cerevisiae will be more efficient in improving egg quality and health of laying hens in the period after peak production.…”

“…The determination of intestinal bacterial population of the ileum and caecum was conducted according to Sugiharto et al (2022). After euthanasia, the digesta of ileum and caecum were transferred into 15 mL containers and immediately analysed for the number of lactic acid bacteria (LAB), coliform and lactose-negative bacteria (LNE).…”

“…Saccharomyces cerevisiae has been widely used as an additive and an alternative to AGP for poultry (Ogbuewu et al, 2018;Morales-Lopez and Brufau, 2013). S. cerevisiae contains vita-mins, amino acids, and enzymes like mannases, glucanases, amylases, lipases, and proteases (Sugiharto, 2022;Ahiwe et al, 2021). The cell wall of S. cerevisiae is primarily composed of αmannan (31% dry mass), mannoprotein, which accounts for approximately 40% dry mass, βglucan (approximately 60% dry mass), and chitin (approximately 2% dry mass) (Ahiwe et al, 2021).…”
