The aggregate index for female fertility was introduced into the national Holstein cattle breeding objectives in 2005, and included five selection criteria, namely days from calving to first service (DTFS), non-return rate at 56 d from first insemina

A new breeding value estimation for mastitis resistance has been implemented in the Italian Holstein dairy genetic evaluation. This breeding value uses indicators derived from test-day somatic cell counts (SCC) in order to predict the breeding value

Feed efficiency in lactating cows is one of the major aspects in modern dairy farm management. Purpose of the present study was to identify sources of variation of body live weight (LW) and feed efficiency traits in a population of 8,516 primiparous

A total of 19.207 test-days, collected on 4 farms from 1999-2006 and belonging to 1109 Valle del Belice dairy sheep were analyzed with a repeatability model. After strict outlier analysis 17.747 records were retained. Animals were reared in an extens

Goat milk, cheese and yoghurt offer an alternative to cow milk products. In Sicily one of the important goat breeds reared is the Girgentana. Traditionally the milk from Girgentana goats was used for nourishment of infants and elderly. Recently, the

La filogenesi della razza Girgentana ancora oggi rimane più o meno sconosciuta sebbene l’ipotesi più valida sembrerebbe quella che la ricollega alla capra Falconeri o Markor (Himalaya). La consistenza numerica della razza nell’ultimi anni ha su

A repeatability test-day animal model was used to investigate heritabilities of somatic cell score (SCS) and milk production traits in Valle del Belice sheep. The heritability estimate for SCS falls within the range reported in literature (0.14±0.03
