  • Optimisation of the weight-reduction plan: enchancment of the Milk Index, or the quantity of milk produced per kilogram of dry matter consumption, is more likely to generate a excessive return on funding contemplating the preliminary feed prices engaged.

  • The management of upkeep charges: some upkeep prices are proportional to the variety of animals current on the farm. These prices embody the next: authorized constraints for the management of manure, animal housing and milking gear wanted to make sure respectable working circumstances, employment prices….
