Yeast culture in the diet of feedlot steers: performance, carcass traits and feeding behavior

Abstract: This study aimed to evaluate the performance, apparent digestibility of diet, ingestive behavior which occurred in two moments, carcass traits, being evaluated constituent and non-carcass components, and also the effect the yeast culture could promote in the peripheral temperature of rumen, hull and body temperature. The diets consisted of a constant ratio of 50% forage (maize silage) and 50% concentrate. Thirty-six steers, ½ Angus Nelore, with average age of 11 months and average initial body weight of 339.5±… Show more

“…In this study, there was no signi cant effect of AY levels on growth performance of these animals, corroborating with Molist et al (2014) and Jiang et al (2015). The lack of effect of AY supplementation on piglet performance in the current study may have occured because according to some researchers the effect of yeast supplementation is more pronounced in animals subjected to sanitary challenges (Finck et al, 2014;Neumann et al, 2020), which was not the case in the current study. Additionally, although there were no signi cant differences between treatments, it was observed that the AY supply promoted a considerable numerical increase in the gain:feed of the nursery piglets.…”
