    Advances in livestock systems are associated with the implementation of technologies in production and improvment of their income. The aim of this research was to examine the identification and implementation of technological packages and their relationship with the variability of the production in the dual purpose cattle of Manabi - Ecuador. Two climatic zones are distinguished: 1) Tropical dry forest and 2) Tropical rain forest. Twenty five (25) technologies grouped into six technological packages (TP) were selected by using qualitative and participatory methods. Interviews were conducted in a sample of 41 farms to assess the implementation of technological packages, using descriptive statistics, Sperman correlations and multiple regressions. The higher degrees of implementation correspond to animal health (76.2 %), equipment (55.6 %) and feeding (55.5 %). Correlations (P<0.01) between TP of feeding, with equipment (0.711) and reproduction (0.774) were evidenced. The variability in milk production (30 %) is explained by the TP of land use in the Tropical dry Forest and by the TP animal health in Tropical rain forest. This research facilitates preliminary results about the identification of a number of technologies that are implemented in the dual purpose cattle of Manabi - Ecuador. Moreover, all animal production systems being seeking a dynamic balance of technologies that allows farms migrate to more efficient processes without losing the main attributes, in this case of the dual purpose cattle systems.

    Technical, social and commercial profile of the Manchega dairy sheep farms in South-Central Spain
    (2014) Rivas, Jose; Garcia, Anton; Toro-Mujica, Paula; Angon, Elena; Perea, Jose; Morantes, Martina; Dios-Palomares, Rafaela
    Manchega sheep farms are characterized by technical, social and commercial aspects of the protected designation of origin "Queso Manchego". The data was obtained through surveys with stratified random sampling and proportional allocation, representing 17.25 % of the population. The characterization was obtained by analysis of descriptive statistics. Groups were formed based on the size and use of technology and compared using a multivariate ANOVAC. The typical farm responds to a mixed crop-livestock extensive system of pastoral type (85 %), with 888 sheep and 1,124 ha total area, 18 % of this area is used in agriculture, mainly grain and forage, the rest of the ST is natural grass, fallow land and wastelands which are used by grazing. The farmer is 48 yr old, married, with one child; there is hope for continuity in the activity (91 %), and generational handover (74 %). The marketing is done by 91 % for long or traditional commercial channels and only 9 % for short or alternative channels (9 %). The greater challenge is associated with high input prices and low product prices. The competitive advantages of the farms are on the one hand the low level of investment and the realization of low-yield farming, aspects that give it flexibility. From the groups by size and technology use different production models emphasizing small and large farms with low use of technologies and large with high use of established technology.
