The annual value of beef and veal production was calculated using provided separately the annual average price of bone-in beef (for soup) per 1 kg and veal per 1 kg in the dataset Annual Average Retail Prices of Food in Latvia, 1913-1939. In order to calculate the value of production of beef and veal, the annual average price of bone-in beef (for soup) and veal was calculated per 1 tonne and multiplied by the annual volume of beef and veal.
The publications provide data on total annual volumes of sheepmeat. The annual value of sheepmeat production was calculated using provided the annual average price of sheepmeat per 1 kg and lamb meat per 1 kg in the dataset Annual Average Retail Prices of Food in Latvia, 1913-1939. In order to calculate the value of production of sheepmeat, the annual average price of sheepmeat and lamb meat was calculated per 1 tonne and multiplied by the annual volume of sheepmeat.
The annual value of milk was calculated using the annual average price of milk (non-skimmed) per 1 litre in the dataset Annual Average Retail Prices of Food in Latvia, 1913-1939. In order to calculate the value of production of milk, the price of 1 litre of milk (non-skimmed) was converted into a price per kg (density of milk is approximately 1,033 kg/m3, therefore 1 litre of milk weighs 1,03 kilogram), then it was calculated per 1 tonne and multiplied by the annual volume of milk.
The publications provide data on total annual volumes of butter.

The annual value of eggs was calculated using the annual average price of eggs per 10 pieces in the dataset Annual Average Retail Prices of Food in Latvia, 1913-1939. In order to calculate the value of production of eggs, the price of eggs was calculated per 1 egg and multiplied by the annual volume of eggs.
