Objective: This study was conducted to evaluate the chemical composition of Yoghurt manufactured by different whey levels during the different storage periods.

Methods: Yogurt samples were manufactured (day one) from five different levels of whey (A, B, C, D, and E), transported to the laboratory in an ice box, and stored at 7°C for 14 days. Samples were analyzed for total solids, moisture, ash, curd protein, fat, pH and acidity at 1, 7 and 14 days.

Results: The results showed that fat, protein, total solids, ash, and pH were high in A and low in E, except for acidity which was increased in E low in C. During storage fat, protein, ash contents, and pH decreased to a minimum at day 14, except for total solids and acidity increased to a maximum at day 14. Towards the end of storage, the fat content slightly decreased in E and increased in A. The protein content reduced somewhat towards the end in E and increased in A. The total solids and ash contents somewhat reduced in all treatments at the end of storage, while acidity increased towards the end of storage in all treatments.
