Answer to Some Questions and Comments On Our Work.
1 - that presented in the page of Engormix and in that of Animal Production, it is not a complete work. It is the Poster of a Summary presented to a Congress. Anyway, the main conclusion is that the weight average of the pigs to the weaning is bigger in the paridera of field type UNRC, comparing with the other two parideras types: This bigger weight to the weaning is important if we accept that the compensatory growth doesn't exist or it is very low in the pigs postdeste (what is endorsed by our own experience and for numerous scientific publications). Also, in general, the three types of evaluated parideras allow performances or reasonably good productive indexes outdoors for a system. Regrettably we have not still arrived, to a definitive conclusion about the value or real utility of the thermal insulation in this parideras type. It can consult himself a similar complete work with a discussion and more extensive conclusions (Another rehearsal) in the page Web of In Vet (Veterinary Investigation). Buenos Aires. Argentina: URL: http://www.fvet.uba.ar/invet/index.htm
2 - the main dimensions of the parideras (Long, wide and high) they are in the text of the Poster (Material and Methods). We could send for e-mail, to who requires it, the constructive planes of the paridera type UNRC and a listing of the necessary materials. It is necessary to clarify that the paridera type UNRC has bigger cost in manpower and in materials that the conventional parideras type arch (Also well-known as Arch English Type). The durability, for the type of materials and construction of the paridera UNRC is bigger than in the type Arch, being bigger the weight of the pigs to the weaning.
3 - in the complete work mentioned previously (InVet) it was included, like one of the treatments, Parideras of Front Open with cement floor and bed (it could take as a semiconfinamiento). Without place to doubts, the two types of evaluated field parideras (Arches and type UNRC), they had very superior results.
4 - thanking the interest for our work, we send to all you an affectionate greeting. |
