Economics young stock rearing (in Dutch)

Notas do Editor

  1. The 1% to 99% percentiles is €0 to €186² The 1% to 99% percentiles is €28 to €55³ The 1% to 99% percentiles is €0 to €274 The average loss per successful reared heifer was calculated as the sum of average loss of dead young stock (€8/successful reared heifer) and culled heifer (€26/successful reared heifer). The calculation for the losses can be referred to equation 2. 5The average total costs of successful reared heifer’s 5% to 95% percentile were not possible to be determined because it was summed up with the average loss per successful reared heifer. The 5% to 95% percentiles of average subtotal costs per successful reared heifer varied from €1423 to €1689
