What is scoring ?

Scoring is a photo of an animal the D-day.this photo is constituted by 19 posts which describe muscular development (5), skeletal development (5), state of fleshing, functional aptitudes, and other stages.

Notation :for each post on the animal, the scorer as to use the note 1 to 10

Use :Global DM et DS are used for indexation and qualification with the same level than birth weight (ease of calving) and weight at weaning (growth potential) in to purpose to have an genetic evaluation with BLUP (Best Linear Unbiased Prediction) system.Hereditary of these characters is high (0,3 à 0.4)
