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

Abstract

Objective Objective: To evaluate the digestibility parameters of growing cattle when fed Enogen Feed corn. Study Description Study Description: Seven cannulated Holstein steers were used to determine the effects on digestibility when fed Enogen Feed corn (Syngenta) as whole-corn or processed as dry-rolled at ad libitum intake. The Bottom Line The Bottom Line: When Enogen Feed corn was fed in an ad libitum fashion to growing calves, dry matter and organic matter are digested to a greater extent relative to yellow corn.

“…Research in steers reported linear increases in in situ DM degradability with increasing proportions of Enogen corn in a dry-rolled corn blend (Horton and Drouillard, 2018). These observations agree with a previous report in which Enogen corn grain was fed to beef cattle (Johnson et al, 2020). As discussed earlier, ECS had a greater estimated OMDI (resulting from greater starch content and 30-h NDF digestibility and lower ADF and lignin compared with CON), which is in line with the observed trend for greater DMD of the ECS diet.…”

“…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). Johnson et al (2020) reported that increases in feed efficiency could be a result of improved dry and organic matter digestibility when feeding Enogen corn to growing calves.…”

Johnson et al (2020) reported that increases in feed efficiency could be a result of improved dry and organic matter digestibility when feeding Enogen corn to growing calves. In other studies, however, few to no production effects were reported when ECS was included at 12, 24, or 80% of dietary DM or when included as grain in both steer and finishing beef cattle diets (Schoonmaker et al, 2014;Brinton et al, 2020a;Rusche et al, 2020).…”
