+ | - Dairy cows: Milk yield and slaughter weights for 2021 have been slightly corrected in the official statistics. | ||
+ | - Heifers: 2021 slaughter weights have been slightly corrected | ||
+ | - Male beef cattle: In some years, slaughter ages and slaughter weights have been updated | ||
+ | - Numbers of laying hens, pullets and broilers were corrected in the years before 2013. The numbers are higher than in earlier submissions.. | ||
+ | - Sows: For several federal states, the number of piglets per sow and year was corrected for the year 2021. | ||
+ | - Fattening pigs: for several federal states the growth rates, start weights and final weights for the year 2021 were corrected. For Saxony and Saxony-Anhalt (no more recent data available than 2016 or 2017) the corresponding data from the neighboring federal state of Thuringia was adopted instead of keeping the last known value as was previously the case. | ||
+ | - Broilers: Update of the national gross production of broiler meat in 2021. | ||
+ | - Laying hens and pullets: due to new weight data for laying hens for 2021, the starting and final weights of laying hens have been recalculated for the entire timeseries. Since the initial weight of the laying hens corresponds to the final weight of the pullets, this also has (small) effects on the energy requirements and excretion of the pullets. | ||

+ | - Application of sewage sludge: Replacement of extrapolated activity data in 2021 with data from the Federal Statistical Office and corrections of activity data for years after 2006. | ||
