Resumo: | This study aimed to verify the effects of supplying different energy patterns on ingestive behavior of feedlot-finished cattle. Twenty-seven pure and crossbred Charolais or Nellore steers with an initial average age and weight of 22 months and 252.8 kg, respectively, were used. Three treatments were carried out, two of them with an increasing rate of concentrate in the diet during the finishing period (IT5 and IT10) and one with constant roughage to concentrate ratio (CT). The experimental design was a completely randomized design with three treatments, five periods, and nine replications. Feeding time was higher for CT (4.31 hours) when compared to IT5 (3.85 hours). Steers from the treatment IT10 remained longer in lying leisure (8.14 hours) when compared to the treatment CT (7.24 hours). A superiority of chewing per ruminated bolus was observed in IT10 (58.59 seconds) when compared to IT5 (54.11 seconds) whereas a higher number of ruminated bolus was observed in TC5 (534.68 ruminated bolus day?1) when compared to IT10 (473.77 ruminated bolus day?1). Animals from CT presented a higher dry matter intake (9.54 kg day?1) than those from IT10 (8.63 kg day?1). Steers from CT and IT5 showed a higher NDF intake (3.63 and 3.58 kg NDF day?1, respectively) when compared to IT10 (3.29 kg NDF day?1). The constant energy pattern increases feeding time and dry matter intake. The one of less vigorous growth increases the number of bolus ruminated per day, while the one of more vigorous growth increases idle time and chews per bolus and decreases the intake of neutral detergent fiber. |

Foram utilizados 27 novilhos, puros e cruzados das raças Charolês ou Nelore com idade e peso médios iniciais respectivos de 22 meses e 252,8 kg. Utilizaram-se três tratamentos, sendo dois com taxa crescente da participação do concentrado ao longo do período de terminação (TC5 e TC10) e um com relação volumoso:concentrado constante (TC). O delineamento experimental foi o inteiramente casualizado, com três tratamentos, cinco períodos e nove repetições. O tempo de alimentação foi maior para o TC (4,31 horas) em relação ao TC5 (3,85 horas). Os novilhos do tratamento TC10 permaneceram mais tempo em ócio deitado (8,14 horas) em relação aos do tratamento TC (7,24 horas). Houve superioridade do tempo de mastigadas por bolo ruminado do TC10 (58,59 segundos) em relação ao TC5 (54,11 segundos) e maior número de bolos ruminados do TC5 (534,68 bolos ruminados por dia) em relação ao TC10 (473,77 bolos ruminados por dia). O TC apresentou maior consumo de matéria seca (9,54 kg dia-1) que o TC10 (8,63 Kg dia-1). O TC e TC5 demonstraram maiores consumos de FDN (3,63 e 3,58 kg de FDN dia-1, respectivamente) que o TC10 (3,29 kg de FDN dia-1). O padrão constante de energia aumenta o tempo de alimentação e consumo de matéria seca, o de crescimento menos acentuado aumenta o número de bolos ruminados por dia, enquanto o crescimento mais acentuado aumenta os tempos de ócio deitado e mastigadas por bolo e diminui o consumo de fibra em detergente neutro.UEL2018-11-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3205710.5433/1679-0359.2018v39n6p2703Semina: Ciências Agrárias; Vol. 39 No. 6 (2018); 2703-2716Semina: Ciências Agrárias; v. 39 n. 6 (2018); 2703-27161679-03591676-546Xreponame:Semina.
