    Semen was collected from 10 Black Castellana roosters and the classic sperm variables (ejaculate volume, sperm concentration and sperm motility) examined. In addition, the hypo-osmotic swelling test was used to investigate sperm cell membrane integrity, and acidic aniline blue staining used to screen for morphological abnormalities (including acrosome integrity) and to examine the condensation status of the chromatin. The latter was also examined by Gram staining. Large and small semen volumes were associated high and low sperm concentrations respectively (R2=0.04, P>0.05).

    Multivariate Classification models to classify real farm conditions Iberian pigs, according to the feeding regime were developed by using fatty acids composition or NIR spectral data of liquid fat samples. A total of 121 subcutaneous fat samples were taken from Iberian pigs carcasses belonging to 5 batches reared under different feeding systems. Once the liquid sample was extracted from each subcutaneous fat sample, it was determined the percentage of 11 fatty acids (C14:0, C16:0, C16:1, C17:0, C17:1, C18:0, C18:1, C18:2, C18:3, C20:0 and C20:1).

    Data from the 1990-1994 period presented in the "Brazil's Initial National Communication" document indicated that the country is one of the top world greenhouse gas (GHG) emitters. A large majority of Brazil's GHG emissions come from deforestation mainly of the Amazon biome for agriculture and livestock land uses. This unique inventory is now out of date.

    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. Present work is part of a large Project whose objective is the characterisation of the carcass and meat from 7 Spanish goat breeds. Thirty kids, 15 per breed, were slaughtered at 4,5 kg, including head and offal. Half of them were fed with natural milk, the other half with artificial milk.

    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. Throughout three seasons (autumn, winter and spring) weight and BCS of 5634 ewes at lambing and weaning were recorded and 5786 lambs were weighed fortnightly form birth to weaning. Season had a significant (p>0.01) effect on weight and BCS of ewes and on lambs average daily gain.

    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). The aim of this work is to characterize both systems of production and to obtain data on the behaviour of the race in order to advise farmers belonging to the association. A total of 22 Burguete colts, 12 lechales and 10 quincenos, were slaughtered. Both cases included males and females.

    Among the autochthonous breeds in Spain, the Ripollesa sheep breed is the most common in Catalonia. It is rustic, with a convex profile, white wood of entrefine type and a characteristic pigmentation. Following the recommendations of the FAO, the morphologic characterization of the Ripollesa ewe has been carried out, as well as the analysis of its variability. A quantitative study from twelve zoometric measures and weight was carried out in a total of 224 females.

    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. The evaluation is based on technical, economical, environmental and social indicators derived from a SWOT analysis of the system. The assessment has been made by the comparison of two commercial flocks managed under different environmental conditions by means of specific nutrition and reproduction practices.
