“…Moreover, Spirulina addition may beneficially alter intestinal microbial population with a reported increase in Lactobacillus sp. and a decrease in E. coli population [ 49 ], as well as improving gut morphology with higher villi length and increasing goblet cells [ 50 ]. The significant increase in relative intestinal weight observed in the present study with Spirulina addition could be involved in the adaptation to low feed intake, which subsequently plays a role in compensating the reduction in feed efficiency of heat-stressed birds [ 51 ].…”

“…However, the present results showed that Spirulina supplementation to heat-stressed broilers at 1% improved carcass composition. Dressing percentage was improved by Spirulina addition at 2 g/kg feed with no effect on abdominal fat pad [ 50 ]. Hajati and Zaghari [ 48 ] supplemented Spirulina at the levels of 2.5 or 5 g/kg diet and reported increases in the relative weight of the breast in quail reared under normal environmental conditions.…”

The modern broiler industry faces huge challenges to keep high production quality and quantity, especially under environmental heat stress conditions. The negative effect of heat stress on broiler productivity is mediated by oxidative stress induction. The blue-green alga (Spirulina platensis) has many applications in poultry nutrition with the high levels of bioactive antioxidant compounds, which can alleviate the oxidative stress damage induced by high ambient temperature. The current study was designed to investigate the effects of dietary Spirulina inclusion at different levels on growth performance, redox status, carcass traits, meat quality, blood hematology, and metabolites profile of broilers subjected to cyclic heat stress. A total of 300 one-day-old Cobb-500 broiler chicks were recruited. Starting from day 21 to 42 of age, birds were randomly divided into five treatment groups with 6 replicates × 10 birds per group, where the first one was provided with the basal diet and reared under normal thermal conditions (23 ± 1 °C) to serve as a negative control. Meanwhile, the other four groups were exposed to cyclic heat stress (34 ± 1 °C for 8 h per day) and were fed a basal diet supplemented with Spirulina at a concentration of 0, 0.5, 1 or 1.5%. Spirulina supplementation to heat-stressed broilers was able to alleviate the negative impacts of heat stress on the final average daily gain, body weight and feed conversion ratio, with the best impact observed among the chickens fed 1% Spirulina. Hematological results indicate increasing hemoglobin and hematocrit levels with Spirulina supplementation compared to the non-supplemented stressed group. Further, Spirulina supplementation significantly influenced blood lipid metabolites marked by reduced serum cholesterol and low-density lipoprotein (LDL), and increased high-density lipoprotein (HDL) levels. The lipid peroxidation level was reduced (p < 0.05), while the antioxidant enzyme activity was increased with Spirulina supplementation to the heat-stressed group. Spirulina supplementation at 0.5 or 1% improved carcass dressing, breast and leg percentages. It can be concluded that dietary Spirulina supplementation at 0.5 or 1% to broiler reared under heat stress conditions can effectively improve broiler production performance and balance the redox status.

“…For that reason, it has been used as a functional feed ingredient in broilers [ 18 ]. In much of the research, it has been used as a growth promoter [ 14 , 19 ], a replacer of AGP [ 20 ], a gut health regulator [ 21 ], and an immunostimulator [ 22 ] in broilers. According to Bonos et al [ 18 ], PUFAs found in spirulina increase the PUFA content of thigh meat in broilers.…”

“…Phenolic, flavonoid, and antioxidant contents have a synergistic effect that improves broiler meat production [ 23 ]. Spirulina is relatively expensive to produce, purchase, and is not as widely available as other feed additives [ 24 ], even though many researchers [ 19 , 22 ] reported Spirulina supplementation to be cost-effective for improving broiler growth and meat quality.…”

“…It was also found that it exerts nutritional properties such as anti-diabetes and anti-obesity activities, while it could be used as an agent against heavy metal toxicity or as anti-microbial agent; Arthrospira contains a relative high content of antioxidants, vitamins, and trace elements and therefore belongs to the category of superfoods with great potential to be used as ingredient for the development of functional foods/feed [30][31][32]. A. platensis has been successfully incorporated in various food products, such as cookies [33], bread [34], pasta [35], cheese [36], etc., or in feed for feeding fish [37], poultry [38], piglets [39], etc. Moreover, A. platensis is a photosynthetic and alkalophilic microorganism which might provide easier cultivation facilities (no sterilization needed, low contamination potentials, etc.)…”

The enzyme alkaline phosphatase (ALP) is gaining interest because it exerts bioactive properties and may be a potentially important therapeutic agent for many disorders and diseases. Microalgae are considered an important novel source for the production of diverse bio-compounds and are gaining momentum as functional foods/feeds supplements. So far, studies for the production of ALP are limited to mammalian and partly to some heterotrophic microbial sources after its extraction and/or purification. Methods: Arthrospira was cultivated under P-limitation bioprocess and the effect of the P-limitation degree on the ALP enrichment was studied. The aim of this work was to optimize the cultivation of the edible and generally-recognized-as-safe (GRAS) cyanobacterium Arthrospira platensis for the production of single-cell (SC) biomass enriched in ALP as a potential novel functional diet supplement. Results: The results revealed that the relationship between intracellular-P and single-cell alkaline phosphatase (SC-ALP) activity was inverse; SC-ALP activity was the highest (around 50 U g−1) when intracellular-P was the lowest possible (around 1.7 mg-P g−1) and decreased gradually as P availability increased reaching around 0.5 U g−1 in the control cultures. Under the strongest P-limited conditions, a more than 100-fold increase in SC-ALP activity was obtained; however, protein content of A. platensis decreased significantly (around 22–23% from 58%). Under a moderate P-limitation degree (at intracellular-P of 3.6 mg-P g−1), there was a relatively high SC-ALP activity (>28 U g−1) while simultaneously, a relative high protein content (46%) was attained, which reflects the possibility to produce A. platensis enriched in ALP retaining though its nutritional value as a protein rich biomass source. The paper presents also results on how several parameters of the ALP activity assay, such as pH, temperature etc., and post-harvest treatment (hydrothermal treatment and biomass drying), influence the SC-ALP activity.
