Effect of three types of pig house’s floors (deep bed, solid floor and slat floor) for finishing pigs in farm

摘要

As a result of the investigation and experience in pig′s production, at the moment, there are greater knowledge and conscience with respect to the pig′s welfare and its effect on the indicators of productivity and quality for the market. With the purpose of evaluating, from the technical point of view and from the building costs, the effect of 3 physical structures of houses, deep bed floor, solid floor and floor "slat", for bristles in finishing phase; an experiment with the respective structures was designed, in commercial farm conditions. It has been used the facilities (sheds) of 3 located pigs and poultry farms in the Carabobo State. It was made in a first level of analysis, a bi dimensional of variables analysis through the ANOVA method, to determine in preliminarily the effect between groups of (EFC) on the pool of response indicators (R), then, in a second phase we applied the linear regression equation model. Where physical structure variable of corral (EFC) is located in the right hand side of the equation, as controlled factor, whose effects are wanted to measure. The results show that effectively the group effect is significantly different, that mean, there is variability on most of the IR given the EFC, where animals locate. On the other hand, regression analysis allow to confirm that as much it is going towards no conventional physical structures of floor, like the one of deep bed, a significantly positive effect is observed on the following R: gaining life, exit to slaughter house, conversion index, discard, and daily gain in the phase. The most economic structure, if all the costs of the investment for the construction of EFC are taken into account, which includes the structures for cleaning of excretes, like oxidation lagoons, etc., it is the structure of corral of deep bed type.
