AVIAGEN has released its 2019 broiler performance objectives that highlight genetic progress made by its Ross 308 in the past five years.

The updated guidelines now suggest a target FCR for birds grown to 2.5kg of 1.53, down from 1.62 in its previous performance objectives.

Breastmeat yield is also up 2.08% to 23.68%.

Aviagen said the targets reflected “continued genetic improvement” and could be achieved in the field under good management conditions.

The firm also issued a new nutrition guideline, but recommendations  remained unaltered.
