The effect of storage and cooling time (0, 1, 3, 7 and 28 days) on the nutritional quality of guinea fowl (Numida meleagris) was assessed in terms of crude protein, moisture, ash, fat, carbohydrate, minerals (calcium, zinc, iron and potassium) and microbial content. Crude protein was determined using Kjedahl method, moisture, ash and fat content were determined using AOAC methods, carbohydrate was estimated by difference and the minerals using AAS methods (for Calcium, Zinc and Iron) and AES (for Potassium). The result of crude protein, moisture and fat content were observed to decrease as storage time increases. Moisture content ranged from 67.70 to 66.50%, ash content from 0.98 to 1.01%, fat content from 2.31 to 2.19%, crude protein content from 20.20 to 19.13% and carbohydrate content from 8.79 to 11.17%. The ash content fluctuates between the same ranges while the carbohydrate content increases with increased in storage time. The minerals content decreases with increase in storage time and the microbial analysis shows freezing inhibited the growth of bacteria which is the main cause of meat spoilage. The study showed that the meat samples could be kept in a frozen state without spoiling but the nutritional content where altered as storage time increased.
