Abstract: Performance, carcass characteristics and ingestive behaviorof steers fed with silages of different maize hybrids  [Desempenho, características da carcaça e comportamento ingestivo de novilhos alimentados com silagens de diferentes híbridos de milho] ABSTRACTThe objective of this study was to evaluate the performance, carcass characteristics and ingestive behavior of feedlot steers fed with three maize hybrids: Maximus VIP3, Defender VIP and Feroz VIP. The experiment lasted 112 days, weighing animals four time… Show more

“…Vials containing only inoculum were used for blank correction. Once filled, the vials were sealed with rubber stoppers and aluminum caps, shaken and placed in an incubator (Shel Lab, Sheldon Manufacturing, Inc., Cornelius, OR, USA) at 39 ± 0.5 • C. The gas pressure in the headspace was measured manually by inserting a sterile needle connected to the pressure transducer at 3,6,9,12,15,18,21,24,30,36,48,60,72,96, and 144 h after inoculation. The volume of gas produced was estimated from the pressure values as proposed by López et al [13].…”

“…The silage resulting from harvesting maize whole-plant at the dent grain stage (R5) was different among the hybrids in terms of chemical composition, with a relatively low NDF content and high starch concentration for the Maximus hybrid [21].…”

“…where ADCG = average daily carcass gain; ACG = average carcass gain (kg) during the feedlot period, and FP = feedlot period (days). The efficiency of transformation of the dry matter intake into carcass (ECC) was also calculated, expressed in kg DM kg carcass -1 , calculations performed as proposed by Horst et al (2019).…”

“…Based on the period of 70 days of feedlot, the average daily carcass gain (ADCG) in kg day -1 and calculated as following: = average daily carcass gain; ACG = average carcass gain (kg) during the feedlot period, and eriod (days). The efficiency of transformation of the dry matter intake into carcass (ECC) was , expressed in kg DM kg carcass -1 , calculations performed as proposed by Horst et al (2019). obtained for each variable were tested for normality by the Shapiro-Wilk test (PROC ) and for homogeneity by the Bartlett test (PROC GLM).…”
