Selling animal products is one of many sources of income, especially, butter, milk, and cheese. I recorded the income obtained from this for many weeks for one of my female respondents. Unfortunately, this income source has been cut off for a few weeks because her cow was sick and I gave her advice to take her cow to the local veterinary clinic and she did.
From a gender point of view, it is common for women to control the income generated from livestock products like milk, butter, cheese, poultry, and eggs i,e, men do not control it, however, in extensive farming systems, they may. Generally, this kind of income source is owned and controlled by the women in the area.
