Comportamento alimentar durante a suplementação diurna de cabritos F1 (Boer x SRD) criados em pastagem nativa.

Abstract

It was aimed at with this work to evaluate the alimentary behavior during the supplementation of kid goats Fl (Boer x SRD) finished in native pasture, 24 were used bovid, no castrated, with weight alive (PV) initial of 15 kg and 120 days of age. The experimental diets were constituted by pasture native "ad libitum" and growing levels of concentrated (0,5; 1,0 and 1,5% PV). The concentrate went to the base corn ground, bran, soy crumb, cotton pie, limestone, bovid mineral nucleus and soy oil, seeking to assist a daily earnings of 200 g for the largest supplementation level. Three evaluations were accomplished, in which eight animals were observed every ten minutes, repeated the months of June, July and August. There was not effect of the supplementation in the time of leisure. It was observed that the time of solid ingestion increased with the increase of the supplementation level, the animals that you/they received 1,5% of the concentrate weight reflected that increase in the reduction of the time spend with rumination. The period in that the pasture had his/her reduced (August) quality provided larger time of solid ingestion and smaller time of rumination. In percentile terms the month of July was what presented larger consumption of concentrated and larger leisure, they put the time spend with rumination for the animals didn't differ of August. The animals that received 1,0 and 1,5% of his/her concentrate weight were similar amongst themselves in the ingestion of dry matter in grams per minute. The animals, independently of the level of appraised supplementation, they spent more time with concentrate consumption as if it characterized the drought period.
