Agronomy, Horticulture and Plant Science Faculty Publications

Ethiopian mustard (Brassica carinata A. Braun) is a non-food oilseed crop that has received attention for its potential as a low-input biofuel feedstock suitable for production in the semiarid regions of the Northern Great Plains (NGP). Because B. carinata is a new crop to the NGP, the best management practices have yet to be developed. The objective of the study was to evaluate the effects of N fertilizer rate on seed yield, seed oil concentration, and oil yield of B. carinata and to determine the economic optimum N fertilizer rates. Field studies were conducted at two locations in South …

How Good Is Our Kentucky Haylage? A Summary Of 2017-18 Farm Results, Jimmy C. Henning, Jeff Lehmkuhler, Levi Berg, April Wilhoit, Corinne Belton, Tommy R. Yankey

Kentucky Alfalfa and Stored Forage Conference

The ability to harvest moist forage as hay gives Kentucky producers many advantages, including timely harvest, higher forage quality, and less weathering loss over hay systems. The baleage system allows producers to utilize commonly available forage equipment (mowers, rakes, balers) rather than requiring choppers and silo structures or bags. Making high quality baleage requires timely access to bale wrappers.

Hay Prices And Trends, David Knopf

Kentucky Alfalfa and Stored Forage Conference

Kentucky’s large cattle and horse populations require considerable forage, and hay is one of the primary feed sources. The state ranks eighth nationally in the production of dry hay. This paper will look at this important sector of Kentucky’s agriculture production, specifically at the available sources of hay prices and recent price trends.

Three Key Factors To Balance When Choosing A Calving Season Based On Profitability, Matthew Stockton, Devin Broadhead

Cornhusker Economics

Cow producers base major decisions such as calving season on expected economic outcomes which include productivity, input costs, personal capability, individual preferences, markets, and so on. Calving systems are generally categorized into three seasons, spring, summer and fall. Many producers select the spring calving season to maximize the weaned calf weight at the end of the summer grass season. Unfortunately this increases feeding costs since extra nutrition is needed in the spring, prior to pastures being opened. Also due to the widespread adoption of this early spring calving, the mass marketing in late fall often results in depressed calf prices …

Next-Generation Sequencing Identifies Polyunsaturated Fatty Acid Responsive Genes In The Juvenile Rat Cerebellum, Aaron A. Mehus, Aaron M. Dickey, Timothy P. L. Smith, Kathleen M. Yeater, Matthew Picklo

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Dietary n-3 polyunsaturated fatty acids (PUFA) influence postnatal brain growth and development. However, little data exist regarding the impacts of dietary n-3 PUFA in juvenile animals post weaning, which is a time of rapid growth. We tested the hypothesis that depleting dietary n-3 PUFA would result in modifications to the cerebellar transcriptome of juvenile rats. To test this hypothesis, three week old male rats (an age that roughly corresponds to an 11 month old child in brain development) were fed diets containing either soybean oil (SO) providing 1.1% energy from α-linolenic acid (ALA; 18:3n-3; ALA-sufficient) or corn oil (CO) providing …

Per-Ingredient Calorie Information Reduces Calories Ordered More In A Food-Away-From-Home Setting Than Information Provided Per, Christopher Gustafson, Eliana Zeballos

Cornhusker Economics

Obesity rates in the United States have risen dramatically over the past five decades, reaching what many public health officials have referred to as epidemic proportions. A common policy response to this obesity epidemic—which is often attributed to overconsumption of highly caloric, unhealthy foods—has been to increase consumers’ access to nutrition information to help them to make healthier choices. Recently, the increasing frequency of food consumption at restaurants led to the development of nutrition labeling requirements for restaurants with 20 or more locations. The rule, requiring food retailers to post calorie amounts and to make available information about other nutrients …
