THE PRODUCTIVITY AND ALLOCATION OF RESEARCH: U.S. AGRICULTURAL EXPERIMENT STATIONS

The main purpose of this paper is to present estimates of the marginal products and rates of return to the four major categories of agricultural research conducted by U.S. agricultural experiment stations (cash grains, poultry, dairy, and livestock).Productivity Analysis, Research and Development/Tech Change/Emerging Technologies,

MARKETING OF BIOTECH FUNCTIONAL FOODS IN THE US

To date, most research in Europe and the United States has focused on eliciting consumer WTP for biotech foods without directly addressing strategies for marketing them. We use means-end theory to link consumers' knowledge about functional attributes, to their knowledge about consequences and core values, in order to gain insights into valued attributes for developing potential marketing strategies.Food Consumption/Nutrition/Food Safety, Marketing,

Cows in the Corn Grazing Project

Corn is the most productive grass grown in Iowa with dry matter yields often exceeding 6 t/a. Harvesting corn by grazing can provide abundant pasture in mid- to late-summer when pastures in southern Iowa normally make little growth. This approach eliminates harvesting, drying, storage, and transportation costs associated with marketing the grain and leaves almost all of the surplus or waste nutrients in the field. Objectives of this project were to measure animal performance when standing corn crop was the sole feed source for pregnant diary heifers and to increase our understanding of the management practices necessary to optimize the use of this feed source

The Role of Habit, Childhood Consumption, Familiarity and Attitudes Across Seafood Consumption Segments in Australia

Australian consumers hold very favorable attitudes toward seafood, with key drivers to consumption being taste, convenience, diet variety, and health benefits. Nevertheless, despite these positive attitudes, seafood consumption remains below many other countries. In this article, we investigate the influence of habit including regular childhood consumption, familiarity with seafood, and attitudes toward seafood on seafood consumption and consumption occasions. Habit and lack of familiarity with seafood were found to lead to lower levels of seafood consumption, whereas positive attitudes toward seafood were associated with more regular seafood consumption. People who consumed seafood on a regular basis as a child were more likely to be more familiar with seafood and be in the habit of consuming seafood in adulthood. Patterns of childhood consumption occasions were found to be associated with adult consumption occasions. Based on these findings, we discuss possible strategies and behavioral interventions for further investigation, which are grounded in habit theory and are aimed at changing seafood eating habits, increasing childhood consumption, and reducing the lack of familiarity with seafood

The Use of a Vaginal Conductivity Probe to Influence Calf Sex Ratio via Altered Insemination Time

One hundred eighty-nine mixed breed beef heifers from 13 consignors enrolled in the MACEP heifer development project were utilized in this study. Heifers were synchronized by feeding 0.5 mg melengestrol acetate (MGA) per head per day for 14 days followed by an injection of prostaglandin F2a (PGF2a; 25 mg Lutalyse®) 17 days after the last MGA feeding. Each heifer was fitted with a Heatwatch® transmitter on the morning of PGF2a administration to facilitate detection of estrus. Vaginal conductivity measurements were taken using an Ovatec® probe every 12 hours for 96 hours beginning at the time of PGF2a injection. Heifers randomly assigned to produce a female calf were inseminated near the onset of estrus (as indicated by probe values of £ 55 on the decline). Heifers randomly assigned to produce a male calf were inseminated approximately 24 hours after the onset of estrus (as indicated by probe values of ³ 60 on the incline). All heifers not inseminated by 96 hours after PGF2a were mass inseminated in an attempt to impregnate as many heifers as possible. Heifers that were diagnosed as pregnant as a result of the artificial insemination were subjected to ultrasonography for fetal sex determination. Only 70 of the 189 heifers (37.0%) exhibited estrus according to Heatwatch® and incidence of estrus was influenced by heifer average daily gain, reproductive tract score, and disposition score. Heifers receiving a disposition score of 3 (78.7) had a higher (P\u3c.05) probe reading at AI than those receiving a disposition score of 1 or 2 (70.8 and 72.5, respectively). Heifers with probe readings at insemination of 80 - 84 and \u3e 84 had lower (P\u3c.05) pregnancy rates to AI (13.6 and 0.0%, respectively) than heifers with probe readings in the ranges of \u3c 60, 60 - 64, 65 - 69, 70 - 74, and 75 - 79 (35.7, 40.9, 31.4, 35.3, and 26.9% respectively). Heifers that were bred when probe values were increasing had a lower (P\u3c.05) percentage of male fetuses (34.4%) than those bred during a period of decreasing probe values (69.2% male fetuses). These results demonstrate that a vaginal conductivity probe may be a useful tool to determine an insemination time that could potentially alter calf sex ratio

Bringing Agriculture into the GATT: Negotiating a Framework for Action

An exploratory study into the role and interplay of intrinsic and extrinsic cues in Australian consumers’ evaluations of fish.

This study explores the role and interplay of intrinsic and extrinsic cues when evaluating fish quality and in shaping consumers' attitudes toward fish consumption. A sensory analysis of nine different fish including five variants of barramundi was conducted to determine how consumers evaluated the fish on intrinsic cues. Focus groups were then conducted to explore the impact of extrinsic cues on attitudes and purchase intentions. While the sensory analysis revealed distinct differences between barramundi variants on intrinsic cues (notably taste), the focus groups revealed that, as a brand, barramundi is perceived much more favourably and consistently. Consumers used extrinsic cues, particularly country of origin, as surrogate indicators of quality. Aquaculture producers need to ensure intrinsic product quality and consistency, as while consumers use the extrinsic cue of "Australian grown" as a surrogate indicator of quality, as their familiarity and confidence with seafood grows, this overreliance on extrinsic cues may diminish

Organic consumer choices for nutrient labels on dried strawberries among different health attitude segments in Norway, Romania, and Turkey

Consumer interest towards healthy food is driving the growth of the organic food market because consumers perceive organic food products to improve their personal health. Berries have well-known health benefits and show increasing market shares in European markets. This manuscript investigates for the first time how health attitudes relate to organic consumers’ choices for nutrient labels of organic dried strawberry products. We conducted an online survey with 614 consumers from Norway, Romania, and Turkey. All participants consumed and liked strawberries and purchased organic food at least once a month. Participants filled out attitudinal questionnaires and conducted an experimental choice task featuring paired images of packaged organic dried strawberries varying in nutrients content label and other factors. The pooled sample was split into three groups of varying health attitudes for profiling and choice analysis. The results show that broad variations exist in health attitudes among Norwegian, Romanian, and Turkish organic consumers. A non-linear effect of health attitude is revealed, where a moderate health attitude is more strongly associated with the selection of products with increased nutrients content than either a low or a high health attitude. The results highlight the complexity in targeting nutrition labels to organic consumers. Finally, implications and suggestions for organic food operators are discussed along with future research avenues

Determination of early summer pasture conditions to optimize forage and calf productivity and profitability

Forages can be valuable elements in a sustainable production system. The date when animals are first allowed to graze on pastures can impact the quality and amount of forages available. This study explored various factors that influence successful grazing
