The main aim of this work is preservation of Animal and bird product through cryodesiccation. Freeze drying, also known as lyophilisation or cryodessication, is a low temperature dehydration process which involves freezing the product, lowering pressure, then removing the ice by sublimation. This is in contrast to dehydration by most conventional methods that evaporate water using heat. Freeze drying results in a high quality product because of the low temperature used in processing. The original shape of the product is maintained and quality of the rehydrated product is excellent. Primary applications of freeze drying include biological (e.g. birds, animals, bacteria and yeasts), biomedical (e.g. surgical transplants), and food processing (e.g. coffee). The average weight of the pigeon used in this work was 370g; the albino rat has average weight of 302g, while hawks average weight was 497g. The moisture content of pigeon A dropped from 65.75 – 8.03%wb, albino rat moisture content decreased from 65.53 – 9.67%wb and the hawk moisture content also declined in the range of 89.62 – 11.20%wb. The proximate analysis of the crude protein content of the animal indicated pigeon has the highest value in the range of 53.23 – 55.87; hawk crude protein content was slightly higher than the albino rat in the range of 49.87 – 50.25, the crude protein content of the albino rat was in the range of 45.34 – 50.01.
