    The aim of this study was to determine and compare the effect of the removal of the spicules of the penis of guinea pig and chemical castration on weight after 12-hour fast pre slaughter and carcass yield. 72 guinea pigs Type I between 35- 45 days of age were used, the same that were distributed in three treatments, T1 whole animals without castration, T2 animals removed spicules glans and T3 chemically castrated animals with iodized alcohol 2% intratesticular; removal and castration was performed in the fifth week of age. Live weight loss by fasting 12 hours pre slaughter, carcass yield relative to live weight at the end of the production process and post-fasting through design covariance initial weight was evaluated. The weight lost by fasting for 12 hours before slaughter showed no REDVET Rev.

This is concluded that the removal of the spicules of the penis in guinea pigs improves performance at the carcass

    The objective of this work was to characterize and establish a typology of Cotopaxi cattle systems in the northern Sierra region of Ecuador. The data were collected through direct surveys of 212 farmers and reflect the main technical, economic and productive aspects of the farms. The typology was established using multivariate analytical techniques. Cluster analysis revealed four groupings. Group I, defined as Small Family Farms (GPF), Group II, as Family Farms Farms (GMF), Group III, as Technified Family Farms Farms (GMFT) and Group IV, as Very Small Family Farms (GMPF). An ANAVA was applied. The evaluation indicated important differences in the group farms, despite the fact that they are developed in the same agroclimatic environment, operate in the same markets and also have similar information. The result is a varied universe of situations with significant variations between medium and small systems. By scale and by reason of their areas dedicated to livestock and crops and their productive and efficiency results measured as income for each activity and level of expenditure.
