Comportamento ingestivo de cordeiros terminados em campo nativo diferentes suplementos energéticos

Abstract

This work aimed to evaluate the behavior of ingestivo sheep kept in native field, receiving different energy sources. The experiment was conducted on private property in the municipality of Dom Pedrito-RS in the period from May 15 to July 30, 2014. We used 18 lambs castrated without race set, with age and approximate average weight of 7 months and 25 kg. The animals were divided into three groups, arranged in six pickets of 0.2 hectares, with forage offer of 4.5 kg DM/100 kg PV, getting three different dietary treatments: SP-animals kept exclusively in native field, without receiving supplemental; CS-native field + supplementation with bark based ration of soybeans, and M-native field + supplementation with corn-based feed broken. Six evaluations were undertaken of ingestivo behavior, noting the activities carried out by the animals (grazing, rumination, idleness, bit rate, rate of displacement, merícicas Chews and other activities). Animals not supplemented remain longer (P < 0.05) in grazing. Already those who received supplementation ruminaram more time on foot and had higher rate of displacement. The number of bit per day was lower for those who consumed soy hulls, which, along with those who consumed corn ingested more water, being that the latter did not differ from animals that did not receive supplements. Energy supplementation caused differences in behavior of ingestivo lambs.
