Resumo: | This study aimed to evaluate the ingestive behavior and physiological responses of steers under different grazing conditions. Five Nellore steers, weighing an average of 390.78 ± 14 kg BW, were assigned to five experimental treatments: clean pasture without concentrate supplementation (PLSC), dirty pasture without concentrate supplementation (PSSC), clean pasture with concentrate supplementation (PLCC), dirty pasture with concentrate supplementation (PSCC) and free access to pasture without concentrate supplementation (LAPSC). The experimental design was a 5 x 5 Latin Square. The grazing behavior was measured through visual observation at the end of each trial in ten-minute intervals for 24 hours, and the physiological variables comprised rectal temperature, respiratory rate and heart rate. The physiological responses of animals were not affected by treatments. The number of steps performed by the animals kept in treatments PLSC (6.08 steps/min) and PLCC (5.62 steps/min) were significantly lower than those in treatments PSSC (16.84 steps/min) and PSCC (14.58 steps/min), showing increased activity of locomotion in animals in paddocks with weeds.KEYWORDS: heart rate; locomotion; pasture; weeds. |

Foram utilizados cinco novilhos da raça Nelore pesando em média 390,78 ± 14 kg de PV, distribuídos em cinco tratamentos experimentais: pasto limpo sem fornecimento de suplemento concentrado (PLSC), pasto sujo sem fornecimento de suplemento concentrado (PSSC), pasto limpo com fornecimento de suplemento concentrado (PLCC), pasto sujo com fornecimento de suplemento concentrado (PSCC) e livre acesso aos pastos sem fornecimento de suplemento concentrado (LAPSC). Utilizou-se delineamento experimental em quadrado latino 5 x 5. O comportamento ingestivo dos animais foi mensurado por meio de observação visual no final de cada período experimental em intervalos de dez minutos, durante 24 horas, e as variáveis fisiológicas avaliadas foram temperatura retal, frequência respiratória e frequência cardíaca. As respostas fisiológicas dos animais não foram influenciadas pelos tratamentos. O número de passos realizados pelos animais mantidos nos tratamentos PLSC (6,08 passos/min) e PLCC (5,62 passos/min) foram significativamente menores que nos tratamentos PSSC (16,84 passos/min) e PSCC (14,58 passos/min), demonstrando maior atividade de locomoção nos animais nos piquetes com invasoras.PALAVRAS-CHAVE: frequência cardíaca; invasoras; locomoção; pastagens.Universidade Federal de Goiás2012-09-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa Científicaapplication/pdftext/htmlapplication/pdfhttps://revistas.ufg.br/vet/article/view/713210.5216/cab.v13i3.7132Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 13 No. 3 (2012); 282-289Ciência Animal Brasileira / Brazilian Animal Science; v. 13 n. 3 (2012); 282-2891809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/7132/11949https://revistas.ufg.br/vet/article/view/7132/11950https://revistas.ufg.br/vet/article/view/7132/15425Tonello, Cleiton LuizRibeiro, Leonir BuenoBarbosa, Orlando RusHöring, Carla FrancieleZanella, Eisler BernardFurtado, Carlos Eduardoinfo:eu-repo/semantics/openAccess2012-09-29T02:15:59Zoai:ojs.revistas.ufg.br:article/7132Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:26.332083Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
