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 conversion by 4.4% and average daily gain by 6.0%. AbstractIn 2017, a growing calf study conducted at the Kansas State University Beef Stocker Unit determined that feeding Enogen Feed corn as either dry-rolled or whole-shelled yielded a positive feed efficiency response of 5.50%. It is not known what the extent of the feed efficiency response is when the alpha amylase enzyme trait is present in either grain and/or silage. In order to determine the growing calf response to Enogen Feed corn silage when fed with Enogen Feed corn or control corn, 352 crossbred steers of Tennessee origin that were used on a previous study at the Kansas State University Beef Stocker Unit were reallocated to pens based on weight. Steers were fed a total mixed ration once daily for 90 days. The four treatment diets were formulated to provide 50 Mcal net energy for gain/100 lb. Cattle off-test weights tended to be greater for calves fed Enogen Feed corn silage. Overall, feed efficiency improved by 4.40% and average daily gain improved by 6.00% for calves fed Enogen Feed corn silage.

Objective Objective: : To determine the response of growing calves when fed Enogen Feed (Syngenta) corn, containing an alpha amylase expression trait.Description Description: : A total of 384 English crossbred steers having an average weight of 538 lb and originating from Texas were used to determine the effects on performance when fed Enogen Feed corn as either whole shelled or processed as dry-rolled at ad libitum intake.The Bottom Line: The Bottom Line: When fed in an ad libitum fashion to growing calves, Enogen Feed corn improves feed efficiency of growing calves by 5.50%.

Horn flies (Haematobia irritans (L.)) are considered the most important external parasite that negatively affects pasture-based beef systems with losses estimated to exceed $1 billion annually to the U.S. beef industry. Control strategies have relied heavily on insecticide applications to control horn flies and are implemented when the economic threshold of 200 flies/animal have been exceeded. When horn fly populations are maintained below 200 flies/animal by treating them with insecticides then the level of stress annoyance behaviors such as leg stomping, head throwing, and skin twitching decreases while grazing increases. While most stocker operators utilize some type of fly control these are rarely used as a single pharmaceutical technology to aid in performance of the animals. Additional pharmaceutical technologies are utilized in combination of others, with the use of de-wormers and implants showing the largest impact with performance of stockers. The objective of this study was to compare a commercial injectable insecticide, LongRange, to an insecticidal ear tag for horn fly control and determine the impact of weight performance on stockers when fly control technologies were used in combination with implants versus no implants.

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.
