Abstract

A 60 days feeding trial was conducted to study the effects of dietary alginic acid (AA) on growth and haemato-immunological responses in Cirrhinus mrigala fingerlings. One hundred eighty fingerlings were randomly distributed into five treatments in triplicates. Five diets were prepared with graded level of alginic acid and were designated as: control (Basal feed + 0% AA), T1 (Basal feed + 0.2% AA), T2 (Basal feed + 0.4% AA), T3 (Basal feed + 0.6% AA) and T4 (Basal feed + 0.8% AA). Higher weight gain % and specific growth rate (SGR) were observed in T2 group. Feed conversion ratio (FCR) value was found significantly lower in T2 group. Total leucocytes and erythrocytes counts were significantly (P<0.05) increased in T2 group. Highest (P<0.05) haemoglobin content was observed in T2. Higher (P<0.05) serum protein, albumin and globulin were manifested in T2. Albumin/globulin ratio was lowest in T2 group. Higher respiratory burst activity (NBT) was observed in T3. Highest activity of catalase and super oxide dismutase (SOD) were manifested in T2. Lowest lactate dehydrogenase (LDH) and malate dehydrogenase (MDH) activities reported in T2. Overall findings suggested that alginic acid at 0.4% dietary level augments growth and haemato-immunological responses in C. mrigala fingerlings.

Effects of Alginic Acid on the Porcine Granulosa Cells and Maturation of Porcine Oocytes

“…[4] There is extensive use of AA in the food industry and healthcare, including food DOI: 10.1002/mnfr.202300130 additives, thickeners, and excipients in medicines, suggesting a high probability of AA exposure. [5] Previous studies reported that AA has biological activities such as anti-allergic effects mediated by inhibiting mast cell-mediated allergic reactions and histamine release, [6,7] immunomodulatory effects mediated by increasing serum complement and lysozyme concentrations, [8,9] and anti-inflammatory effects mediated by reducing tissue edema and inhibiting the release of proinflammatory cytokines. [10][11][12] Although numerous studies showed the positive effects of AA, relatively little research has been carried out on the reproduction of female mammals, even less in sows.…”

Brown Seaweed‐Derived Alginic Acid: An Efficient and Reusable Catalyst for Pictet‐Spengler Reaction to Access Tetrahydro‐β‐Carboline and Tetrahydroisoquinoline Frameworks

“…[25][26][27][28] Alginic acid have widespread applications in the food / chemical industries, medical sector, water treatment plants, packaging materials and cell immobilization. [29][30][31][32][33] In the chemical industry, alginic acid is primarily used as a heterogeneous Brønsted acid promoter. [34,35] The manipulated alginate materials like alginic acid supported organometallic catalysts or metal ions or nanoparticles can perform significant catalysis in various chemical transformations.…”
