This book was released on 2019. Available in PDF, EPUB and Kindle. Book excerpt: Two growth performance studies and two digestibility trials were conducted to evaluate the effects of feeding Enogen feed Corn silage and corn grain to growing cattle. In Experiment 1, there were a total of four diets offered for ad libitum intake. The four diets consisted of two varieties of corn (Enogen Feed Corn (EFC) vs. negative isoline control corn (CON)) with two different methods of corn processing (dry-rolled corn (DRC) vs. whole-shelled corn (WC)) and were formulated to provide 1.13 Mcal NEg/kg DM. ADG and final BW tended to be greater for calves fed EFC (P 0.10). Feed efficiency was greater for calves fed EFC (P 0.01), improving by 5.50% over calves fed CON corn. In Experiment 2, a digestibility trial was conducted using 7 cannulated Holstein steers fed the same diets from Experiment 1. Ruminal pH was not affected by corn variety (P 0.82). Liquid passage rate was greater for CON-fed calves, which resulted in decreased digestibility. Total tract organic matter (OM) and dry matter (DM) digestibility was greater for EFC-fed calves (P 0.04). In Experiment 3, there were a total of four diets offered for ad libitum intake. Diets consisted of two varieties of corn silage (EFC vs. CON) and two varieties of DRC (EFC vs. CON) and were formulated to provide 1.11 Mcal NEg/kg DM. ADG was greater (P 0.01) for calves fed EFC silage and feed efficiency tended to be greater for calves fed EFC silage (P

Download or read book Evaluation of Alpha Amylase Containing Corn on Finishing Cattle Performance and Digestibilty written by Melissa L. Jolly-Breithaupt. This book was released on 2018. Available in PDF, EPUB and Kindle. Book excerpt: One digestion and four finishing trials were conducted to evaluate the effect of a new corn hybrid containing an alpha-amylase trait, Syngenta Enogen Feed Corn (SYT-EFC) on site and extent of digestion, ruminal fermentation parameters, and feedlot performance. Experiments utilized corn containing the enzymatic gene compared to controls, the near isoline parental corn (NEG) or commercially available corn grain (CON), processed as dry-rolled corn (DRC) or high moisture corn (HMC) in diets with dry [distillers grains plus solubles (DGS)] or wet (Sweet Bran) milling byproducts. The corn grain of the experimental diets were fed as the sole grain source, comprising 100% of the concentrate in the diet. Cattle fed SYT-EFC, processed as DRC with Sweet Bran had increased G:F resulting in feeding values ranging from 103 to 116% of CON or NEG. Steers fed SYT-EFC, processed as DRC with DGS had increased G:F resulting in feeding values ranging from 101 to 107% of CON or 105% of NEG. However, when processed as HMC, feeding SYT-EFC resulted in 96 and 102% that of NEG when fed with Sweet Bran or DGS, respectively. Marbling and 12th rib fat thickness data were mixed among trials with being increased in cattle fed SYT-EFC or observing no detectable difference among treatments. Cattle fed SYT-EFC had greater postruminal starch digestibility compared to NEG resulting in a 2.2 and 6.3% increase in total tract starch digestibility in DGS and Sweet Bran diets, respectively. Overall, feeding corn containing an alpha-amylase trait as DRC would suggest a slight improvement in feed efficiency.

Book excerpt: Three studies evaluated effects of high-amylase corn (Enogen® Feed Corn, EFC) on ruminal digestive characteristics using different processing methods; a 4th study evaluated performance of finishing cattle fed steam-flaked EFC. In study 1, mill-run corn (CON) and EFC were ground through 9-, 6-, or 4 -mm screens, blended to contain 0, 33.3, 66.7, or 100% EFC, and heated to 50, 75, or 1000C (plus a non-heated control). No 2- or 3-way interactions occurred (P > 0.05). Increasing EFC in blends linearly improved in situ dry matter disappearance (ISDMD; P

Book Synopsis Effects of Limit Feeding Cold Stressed Growing Calves in the Morning Versus the Evening, as Well as Bunk Line Sharing on Performance by : Charles A. Sasscer (III)

Download or read book Effects of Limit Feeding Cold Stressed Growing Calves in the Morning Versus the Evening, as Well as Bunk Line Sharing on Performance written by Charles A. Sasscer (III). This book was released on 2021. Available in PDF, EPUB and Kindle. Book excerpt: Two growth performance studies and two digestibility trials were conducted to evaluate limit feeding cold stressed growing calves in the morning versus the evening, as well as bunk line sharing and a study to evaluate the effects of limit feeding corn grain containing an alpha-amylase gene to growing cattle. In the first trial, there was one diet offered at 2.0% of body weight on a DM basis. Diets were formulated to provide 1.32 Mcal NEg/kg DM. The experiment consisted of one treatment fed in the morning (AM), one in the evening (PM), one fed half of their feed in the morning and half in the evening (AM/PM), and two additional groups of cattle (Shuttle AM, Shuttle PM) that were fed in the same pen yet were rotated twice daily utilizing an adjacent holding pen. ADG for calves fed in the evening and/or assigned to share a bunk line was not significantly different (P>0.9) compared to calves fed in the morning and not rotated daily. Feed efficiency was not improved in calves fed in the evening nor shuffled between pens (P>0.98). A digestibility trial was conducted concurrently to the first trial using 6 cannulated Holstein steers receiving the same treatments, less the bunkline sharing. Ruminal pH did not differ between treatments (P > 0.35), and ruminal VFA concentrations of propionate and valerate were higher for PM fed calves while concentrations of isobutyrate and isovalerate were lower for PM fed calves (P0.03). Altering time of feed delivery during times of cold stress and cattle housing management changes digestibility characteristics of the rumen but does not result in any cattle growth performance advantages. In the second experiment, there were a total of four diets offered at 2.2% of body weight on a dry matter (DM) basis. The four diets consisted of two varieties of corn (Enogen Feed Corn (EFC) vs. negative isoline control corn (CON)) with two different methods of corn processing (dry-rolled corn (DRC) vs. whole-shelled corn (WC)) and were formulated to provide 1.32 Mcal NEg/kg DM. ADG and final BW were not significantly different for calves fed EFC (P 0.56). Feed efficiency was not different for calves fed EFC (P > 0.94), or for calves fed DRC (P>0.26). A digestibility trial was conducted concurrently using 8 cannulated beef steers fed the same 4 diets as the second experiment. Ruminal pH was not affected by corn hybrid (P > 0.34). EFC fed cattle produced greater concentrations of ammonia and isovalerate (P
