Effect of Dietary Spirulina Platensis Supplementation on Blood Biochemical Attributes and Metabolic Health in Osmanabadi Goats.

The study evaluated the effect of dietary Spirulina platensis supplementation on blood biochemical parameters in Osmanabadi goats. A total of eighteen healthy Osmanabadi kids aged 3–4 months with an average body weight of 9–10 kg were selected for the experiment. All animals were ear-tagged for identification and housed in a well-ventilated shed under hygienic conditions with provision for individual feeding. Prior to the start of the trial, kids were dewormed with albendazole suspension at the recommended dose. These 18 kids were divided into three groups as control (T0), Spirulina at 0.25% DMI (T1), and Spirulina at 0.50% DMI (T2). Blood samples were collected at 0, 45, and 90 days and analyzed for serum proteins, lipid profile, and renal markers. Spirulina-fed goats showed a numerical increase in total protein and globulin concentrations, while albumin remained stable and albumin:globulin ratio slightly declined, indicating enhanced immune competence. Serum cholesterol and triglyceride levels were reduced in supplemented groups, particularly at 0.50% inclusion, reflecting hypolipidemic effects. Creatinine and urea values remained within normal physiological ranges across treatments, confirming no adverse impact on renal function. Overall, Spirulina supplementation improved serum protein fractions and lipid profile without affecting renal markers, supporting better nutrient utilization and metabolic efficiency. The findings highlight Spirulina’s potential as a safe functional feed additive for enhancing biochemical health and productivity in indigenous goats.
