The influence of some factors (season and age of the first caving, paternal origin, duration of economic use) on milk productivity of cows on farms in the Middle Amur Region

Key Points

• Improving cow milk productivity depends significantly on managing calving seasons and reducing the first calving age.
• Data analysis identified that extending cow productivity to five or more calvings can enhance economic efficiency.
• The study focused on two dairy farms in the Khabarovsk region, highlighting effective management strategies for Black-and-White breed cows.
• Optimizing the timing of calvings also plays a crucial role in maximizing milk output per farm.
