Management Of Late Summer Planted Annual Forages For Grazing And The Impacts Of Novel Sweet Bran Plus Products On Performance And Carcass Characteristics Of Beef Finishing Steers, Devin Jakub
Department of Animal Science: Dissertations, Theses, and Student Research
Two separate grazing studies were conducted to evaluate: 1) the effects of rapeseed inclusion into late summer planted oats on the performance of growing steers during late fall and winter (Exp. 1) and 2) the effects of forage allocation on forage utilization and performance of steers grazing a late summer planted oat-rapeseed mix (Exp. 2). Variation in the corn wet milling process can result in negative effects on animal performance, nonetheless, there remains interest in further exploration and refinement of corn wet milling byproducts to achieve optimal byproduct compositions and cattle performance. Thus, another experiment was conducted to evaluate the …
Risk Of Nitrate Toxicity When Grazing Annual Forages, Mary Lenz
Risk Of Nitrate Toxicity When Grazing Annual Forages, Mary Lenz
Department of Animal Science: Dissertations, Theses, and Student Research
Annual forages provide a valuable grazing resource for producers; however, annuals are prone to accumulating nitrate and toxicity can be a potential challenge. There are multiple publications regarding nitrate toxicity, but few, if any, address grazing high nitrate forages. There is variability on what amount of nitrate is considered toxic to cattle, and information is not available on the frequency producers experience toxicity when feeding annual forages. To understand the incidence of nitrate toxicity in the North Central Region of the U.S., a survey was distributed through the “UNL BeefWatch” newsletter to producers. Though producers appeared concerned about nitrates in …
Backgrounding Calf Management Strategies Using Corn Residue And Double Cropped Forages, Jordan L. Cox-O'Neill
Backgrounding Calf Management Strategies Using Corn Residue And Double Cropped Forages, Jordan L. Cox-O'Neill
Department of Animal Science: Dissertations, Theses, and Student Research
Approximately 70% of calves in the U.S. are born in the spring and weaned in the fall, this results in a large supply of calves potentially available for backgrounding over the winter. Backgrounding systems positively impact the beef industry by efficiently using forage resources available. These systems also provide production value by enhancing the calf’s frame size, mature BW (increase HCW), and health prior to entering the feedlot. In Nebraska opportunities to integrate both crop and livestock production, by backgrounding calves abound. Approximately 13,100 metric tons of corn residue or 34,000 Animal Unit Months are available for grazing in Nebraska. …
Managing Corn Residue And Double Cropped Forages In Crop And Livestock Systems, Kristen M. Ulmer
Managing Corn Residue And Double Cropped Forages In Crop And Livestock Systems, Kristen M. Ulmer
Department of Animal Science: Dissertations, Theses, and Student Research
Integrating crop and livestock systems leads to opportunities to utilize land resources; however, crop producers focus on grain yields and ground cover, while livestock producers see opportunity to graze corn residue or annual forages. After wheat harvest or corn silage harvest, above ground forage production for brassica mixes and oats is greater than forage oats or oat production after high moisture corn harvest. Grazing steers on forage crops after grain harvest provides moderate gains. While annual forages provide good quality forages, corn residue grazing and utilization is still a cost-effective feedstuff for cattle producers. In the short term, grain yields …
