Consumer acceptance of dairy products with a saturated fatty acid-reduced, monounsaturated fatty acid-enriched content
Agriculture-based reformulation initiatives, including oleic acid-rich lipid supplementation of the dairy cow diet, provide a novel means for reducing intake of saturated fatty acids (SFA) at a population level. In a blinded manner, this study evaluated the consumer acceptance of SFA-reduced, monounsaturated fatty acid-enriched (modified) milk, Cheddar cheese, and butter when compared with control and commercially available comparative samples. The effect of providing nutritional information about the modified cheese was also evaluated. Consumers (n = 115) rated samples for overall liking (appearance, flavor, and texture) using 9-point hedonic scales. Although no significant differences were found between the milk samples, the modified cheese was liked significantly less than a regular-fat commercial alternative for overall liking and liking of specific modalities and had a lower liking of texture score compared with the control cheese. The provision of health information significantly increased the overall liking of the modified cheese compared with tasting the same sample in a blinded manner. Significant differences were evident between the butter samples for overall liking and modalities of liking; all of the samples were significantly more liked than the commercial butter and sunflower oil spread. In conclusion, this study illustrated that consumer acceptance of SFA-reduced, monounsaturated fatty acid-enriched dairy products was dependent on product type. Future research should consider how optimization of the textural properties of fatty acid-modified (and fat-reduced) cheese might enhance consumer acceptance of this product
Broken biosecurity?: veterinariansâ framing of biosecurity on dairy farms in England
There is seen to be a need for better biosecurity â the control of disease spread on and off farm â in the dairy sector. Veterinarians play a key role in communicating and implementing biosecurity measures on farm, and little research has been carried out on how veterinarians see their own and farmersâ roles in improving biosecurity. In order to help address this gap, qualitative interviews were carried out with 28 veterinarians from Royal College of Veterinary Surgeon farm accredited practices in England. The results were analysed using a social ecology framework and frame analysis to explore not only what barriers vets identified, but also how vets saw the problem of inadequate biosecurity as being located.
Veterinariansâ frames of biosecurity were analysed at the individual, interpersonal and contextual scales, following the social ecology framework, which see the problem in different ways with different solutions. Farmers and veterinarians were both framed by veterinarians as individualised groups lacking consistency. This means that best practice is not spread and veterinarians are finding it difficult to work as a group to move towards a âpredict and preventâ model of veterinary intervention. But diversity and individualism were also framed as positive and necessary among veterinarians to the extent that they can tailor advice to individual farmers.
Veterinarians saw their role in educating the farmer as not only being about giving advice to farmers, but trying to convince the farmer of their perspective and values on disease problems. Vets felt they were meeting with limited success because vets and farmers may be emphasising different framings of biosecurity. Vets emphasise the individual and interpersonal frames that disease problems are a problem on farm that can and should be controlled by individual farmers working with vets. According to vets, farmers may emphasise the contextual frame that biosecurity is largely outside of their control on dairy farms because of logistical, economic and geographical factors, and so some level of disease on dairy farms is not entirely unexpected or controllable. There needs to be a step back within the vet-farmer relationship to realise that there may be different perspectives at play, and within the wider debate to explore the question of what a biosecure dairy sector would look like within a rapidly changing agricultural landscape
