Animal tissue composition is determinant in the quality of animal products and is influenced by several factors including diet, genetic type, age and sex. Diet effect on Iberian pig's tissue composition is a relevant issue with productive and economic implications, not well understood to date.
Thirty three male tudanca young bulls were used to evaluate 2 production systems (intensive and semiextensive) and 2 slaughter ages (12 and 14 months).
MESMIS methodology (Ridaura et al., 2002) has been tested to assess sustainability of two different commercial flocks within the breeding scheme of the Latxa sheep in the Basque Country.

At present the Race Burguete is regarded as Breed in danger of extinction. The products marketed can be classified in Lechal (the colt once weaned enters the fattener) and Quinceno (foals that once weaned remain several months at grazing and around 15 months of age are fattening).
8 flocks of Ojinegra ewes (n=5634) were studied during a productive cycle (2007-2008) in Teruel (Spain), a low-mountain dry and harsh area. Ojinegra ewes belong to a local breed, of small-medium size, reared under a semi-extensive system of management.
In dairy goat breeds, kids are a subproduct, hence they were weaned as soon as possible. The aim of the present work was to study the influence of lactation system on carcass quality of the two main dairy Spanish goat breeds.
