All indices are Italian indices calculated using the BLUP Animal Model. All indices are expressed in the same scale with 100 as the average.Muscularity and weight increase are measured during the performance test carried out on young bulls at Anaborapi Genetic Station, located in Carru, Italy, where young bulls are reared under similar conditions from 50 days of age to 12 months.

Breeding Index:

Use this index to select sires of potential replacement dams.

Meat Index:

Use this index to select terminal sires.

Muscularity:

Muscularity indexes are calculated using muscular development evaluation and fineness of bone of bulls at 12 months of age using linear scoring.

Weight increase:

Better known as Growth Rate in Ireland, it is calculated on the basis of monthly weights of bulls taken during their performance test. 11 weights are used for each animal.

Birth Ease:

The genetic value of an animal according to it's aptitude to generate easy calving. In Ireland this would be similar to Direct Calving Difficulty, i.e. use a bull with a high figure for Birth Ease on heifers/young cows.

Calving Ease:

The genetic value of an animal according to it's aptitude to generate dams with good calving ability. This would be similar to Maternal Calving Difficulty, i.e. use a bull with a high figure for Calving Ease if you want good replacement heifers with good maternal calving ability.
