| Sumario: | This study presents the nutritional composition of Macrocystis pyrifera, brown seaweed, from the South Atlantic Ocean. Preliminary, we consider the use of this species as food for ovine cattle during critical situations in the Deseado Department, Santa Cruz province. Protein analysis, lipids, total and insoluble dietary fibers, humidity, and ashes determination were measured following the AOAC (2005) protocols. Besides, the crude protein, ethereal extract, dry material, ashes, potassium and sodium were determined by centesimal analysis. The copper determination, previously acid digestion, was made through flame atomic absorption spectrophotometry. The nutritional values of protein, lipids and carbohydrates were low. The copper was low and there is no risk of toxicity for chronic ingestion of the ovine. These results indicate that this seaweed species would be a food supplement of low energy for the ovine cattle. This preliminary work considers experimental studies about the answer animal of this supplement food ‘consume. We will analyze the contributions to promoting alternative food in a critical context in the north Santa Cruz province behind sustainable practices in the harvest seaweed. |
