Cow skin, often known as cowhide, is the outer covering removed when cows are slaughtered for meat processing. This skin is a versatile by- product used not only in the leather industry but also as a culinary ingredient in various parts of the world. In Nigeria, it is popularly referred to as " Ponmo, " while it goes by names like " wele" in Ghana and " kanda" in Cameroon. Though initially tough and requiring meticulous preparation, cow skin has become a beloved delicacy in West African countries, Caribbean regions, and particularly among Nigerians.

Cow skin, or " Ponmo, " is nutritionally unique, though opinions differ regarding its health benefits. Per 100 grams of thick, boiled cowhide, it contains approximately 224. 65 kcal of energy, 6. 80 grams of carbohydrates, 43. 9 grams of water, 46. 9 grams of protein, 1. 09 grams of fat, and 0. 02 grams of fiber. This composition reflects a food item low in fat and calories, with a high protein content. However, its protein profile is notably low in essential amino acids, categorizing it as low- quality protein with minimal biological value.

Cow skin' s popularity in Nigeria and other West African countries goes beyond its taste. Nigerians enjoy Ponmo for its unique texture, which adds variety to stews and soups. In Ijebu- Igbo, a region in Nigeria, Ponmo has become a thriving business, with local producers supplying the skin to consumers across the country.
