Syngenta Enogen Feed Corn Silage Containing an Alpha Amylase Expression Trait Improves Feed Efficiency in Growing Calf Diets

Abstract: Objective Objective: To determine the growing calf response when fed Enogen Feed corn silage containing an alpha amylase expression trait. Study DescriptionStudy Description: Crossbred steers of Tennessee origin (n = 352) were used to determine the effects on performance when fed Enogen Feed corn silage with either Enogen Feed corn or control corn at ad libitum intake.The Bottom Line The Bottom Line: When fed in an ad libitum fashion to growing calves, Enogen Feed corn silage improves the efficiency of feed co… Show more

“…The lack of response in this experiment to silage expressing the alpha-amylase trait contrasts with the positive effects observed when Enogen Feed corn silage was fed to growing steers ( Johnson et al, 2019 ) or finishing yearling steers ( Baker et al, 2019 ). In the growing cattle study by Johnson et al (2019) , feeding Enogen silage at 40% of diet DM without a corn processing coproduct increased ADG and tended to increase DMI, resulting in greater G:F. Feeding Enogen silage at 8% of diet DM combined with corn gluten feed in finishing diets reduced DMI with no effect on ADG, resulting in greater G:F compared with conventional silage ( Baker et al, 2019 ). In contrast to the present experiment, neither of these studies utilized distillers grains as a source of supplemental protein.…”

“…Both experiments also examined the effects of Enogen Feed corn as starch sources in the diets in a 2 × 2 factorial arrangement of treatments. Johnson et al (2019) fed dry-rolled corn at 38.5% of diet DM, while Baker et al (2019) used steam-flaked corn at 74.5% of diet DM. Including Enogen Feed corn as grain either resulted in no effect on cattle performance ( Johnson et al, 2019 ) or reduced G:F ( Baker et al, 2019 ) compared with conventional corn sources.…”

“…To the best of our knowledge, the only other study to date that has investigated the effects of ECS in dairy cattle is that of Rebelo et al (2020), who reported increased DMI and MY but no effect on ECM when ECS was included in the diet of lactating dairy cows, in a replicated 3 × 3 Latin square experiment, at a rate of 48% of dietary DM. However, improved feed efficiency in response to ECS inclusion at 40% of diet DM was previously reported by Johnson et al (2019) in growing steers, in which an increase in ADG and a tendency for increased DMI were also observed. The production responses from the latter experiment are in line with research with beef steers when Enogen was fed in the diet as either grain or silage, or both (Baker et al, 2019;Johnson et al, 2020).…”

“…Feeding experiments with Enogen corn in growing steers and finishing beef cattle have been inconclusive in terms of production responses. Some have reported improved feed efficiency when feeding Enogen corn as silage or grain source or both (Baker et al, 2019;Johnson et al, 2019), whereas similar studies have reported only marginal responses (Schoonmaker et al, 2014;Brinton et al, 2020a,b). To the best of our knowledge, the current experiment and that of Rebelo et al (2020) are the only studies that have investigated the effect of Enogen fed either as grain or as silage in dairy cattle diets.…”
