Curva de secagem e composição bromatológica do capim Tifton 85 (Cynodon spp) no sertão paraibano.

Abstract

The Brazilian semiarid region is characterized as irregular rainfall region, and thus the greatest challenge of rancher in the region to produce Food for the herd, can this technique be minimized by storage and preservation of food in the form of hay or silage. The olãective of this research was to evaluate the chemical composition and the drying curve for hay production Tifton 85(Cynodonspp) in Paraiba backcountry conditions. For determination of the drying curve was used to 0,1,2,3,4,5,6,7,8,9,23,25,27 time and 3 1 hours of exposure to the sun with two replicates of TiRon 85 (Cynodon spp.). The collected material was deposited on canvas the sun to dry, on 1 8 and 19 Jure 2015. The average values for temperature and exposure time to the sun were 32 ' C and 1 0 hours on the Hjrst day and 31 ' C and 7 hours in the second day, respectively. The conditions under which the survey was conducted the Tifton 85 graus (Cynodon spp.) Needs 31 hours of exposure to achieve the ideal point of hay, which is 14 hours of such exposure was indoors, observing the average value of 95.3 % MS.
