<b>Feeding behavior of categories of feedlot-finished beef cattle

Abstract

ABSTRACT. An experiment was conducted to evaluate the feeding behavior of feedlot-finished bulls and cull cows in the Cerrado region of Piauí State, Brazil. Forty Zebu cattle were used, of which 20 steers averaging 283.0 ± 20.82 kg initial body weight and 30 months of age; and 20 cull cows averaging 296.1 ± 17.80 kg initial body weight and 100 months of age. Animals were grouped according to the following treatments: bulls and cull cows, using a completely randomized design. Feeding behavior was evaluated by means of visual observations every five minutes during 24h. Results were subjected to analysis of variance by the F test (p < 0.05) using the System for Statistical and Genetic Analysis -SAEG (version 9.1). The feeding behavior was expected not to affect the feed intake of cull cows and bulls, so that feed management can be the same for both categories. For all variables, there were differences between the categories (p > 0.05), showing that feeding behavior is influenced by the cattle category.

Ingestive behavior of lambs fed relocated and inoculated whole-plant corn silage

“…The fact that the animals in the present study spent more time feeding in the periods 8:00-11:00am and 5:00-8:00pm, in relation to rumination and idling activities, was due to the silage supply at these intervals, stimulating silage intake. In feedlot systems, the feeding time is an important variable that has be managed in the production systems, as it is highly related to diet intake, and consequently, animal performance (Santos et al, 2018).…”

“…In this context, analyzing the feeding behavior allows the adjustment of dietary management in order to achieve better production performance in beef cattle ( 40 ). The particle sorting affects the individual nutrient intake, since there are indications that this sorting of the diet is associated with an increased risk of metabolic diseases ( 41 ).…”

Implicaciones que influyen en el desempeño productivo, características de la canal y de la carne de ganado bovino engordado en corral

“…La edad favorable para iniciar la engorda en confinamiento va de 12 a 26 meses, debiéndose elegir animales que sean compatibles en raza, sexo, talla y peso para lograr una adecuada lotificación y programar el tiempo de confinamiento (Martínez y Matadamas, 1994). La lotificación en el inicio de la engorda en corral es importante por la diferencia en el comportamiento ingestivo y predominancia de jerarquías de las diferentes categorías del ganado (Santos et al, 2018). Esto, además, ofrece ventajas de uniformidad para la comercialización del ganado engordado (Comerford et al, 2014).…”
