Abstract

Sixteen nubian male goats of about 12 months old and initial live weighit of 34,4 kg were kept in metabolical cages lo measure the D M intake. DM, CP, EE, NNE, OM, NDF, ADF and energy digestibility coefficients, TDN content and nitrogen balance of coast cross (Cynodon dactylon (L.) Pers) hay harvested at 45 or 60 days of growth and given as long chopped (3,0 cm) or short chopped (0,35cm) pieces to allow or not the selection of the hay. Blood samples were collected before and 4 hours after feeding, to measure the levels of plasma glucose and urea. It was used a completily randomized design (n= 4) in a 2x2 factorial experiment. The animals fed hay harvested at 45 days consumed better quality food and showed greater DM, CP, OM. ADF, energy digestibility coefficients, plasma glucose and urea levels after feeding and TDN content. The long chopped hay allowed selection by animals and showed an intake of material with greater nutritive value, with greater DM, OM, energy digestibility coefficients and TDN values of the consumed food. There was no difference between time of harvesting and kind of chopping of the hay on the dry matter intake.
