In the past 10 years, the average demand for meat and milk across the world has significantly increased, especially in developing countries. Therefore, to support the production of animal-derived food products, a huge quantity of feed resources is needed. This paper does not present original research, but rather provides a conceptual strategy to improve primary production in a sustainable way, in relation to forthcoming issues linked to climate change. Increases in meat and milk production could be achieved by formulating balanced diets for ovines based on alfalfa integrated with local agricultural by-products. As the central component of the diet is alfalfa, one goal of the project is increasing the yield of alfalfa in a sustainable way via inoculating seeds with symbiotic rhizobia (i.e., Sinorhizobium meliloti). Seed inoculants are already present on the market but have not been optimized for arid soils. Furthermore, a part of the project is focused on the selection of elite symbiotic strains that show increased resistance to salt stress and competitiveness. The second component of the experimental diets is bio-waste, especially that obtained from olive oil manufacturing (i.e., pomace). The addition of agro-by-products allows us to use such waste as a resource for animal feeding, and possibly, to modulate rumen metabolism, thereby increasing the nutritional quality of milk and meat.

At present the olive oil industry produces large amounts of secondary products once considered waste or by-products. In this paper, we present, for the first time, a new interesting olive by-product named “dried destoned virgin olive pomace” (DDVOP), produced by the pomace oil industry. The production of DDVOP is possible thanks to the use of a new system that differs from the traditional ones by having the dryer set at a lower temperature value, 350 °C instead of 550 °C, and by avoiding the solvent extraction phase. In order to evaluate if DDVOP may be suitable as a new innovative feeding integrator for animal feed, its chemical characteristics were investigated. Results demonstrated that DDVOP is a good source of raw protein and precious fiber; that it is consistent in total phenols (6156 mg/kg); rich in oleic (72.29%), linoleic (8.37%) acids and tocopherols (8.80 mg/kg). A feeding trial was, therefore, carried out on sheep with the scope of investigating the influence of the diet on the quality of milk obtained from sheep fed with DDVOP-enriched feed. The resulting milk was enriched in polyunsaturated (0.21%) and unsaturated (2.42%) fatty acids; and had increased levels of phenols (10.35 mg/kg) and tocopherols (1.03 mg/kg).

A great number of cheese dairies and dairy industries in Greece are disposing their wastes, mainly cheese whey, either on land or in surface receivers, in large quantities creating a major environmental problem. A typical agricultural and pastoral provincial town of 70,000 inhabitants, Trikala, became the starting point of this research. A co-treatment of the urban sewage and the dairy wastes in the municipal treatment plant was recommended. The successful application of the above statement is based primarily on the pretreatment of the cheese dairies wastes. So far for cheese whey the recovery of the lactose serum in the contemporary central unit applying membrane technology has been suggested. As far as the wastewaters of the washing and refrigeration are concerned a pretreatment is required for the defatting in a grease trap, the grating, the adjustment of pH and the equalisation in an appropriate tank. Finally, this research has also focussed on the importance of membrane technology in improving the quality of milk and cheese production.

One third of food produced globally is wasted. Disposal of this waste is costly and is an example of poor resource management in the face of elevated environmental concerns and increasing food demand. Providing this waste as feedstock for black soldier fly (Hermetia illucens) larvae (BSFL) has the potential for bio-conversion and valorisation by production of useful feed materials and fertilisers. We raised BSFL under optimal conditions (28 °C and 70% relative humidity) on seven UK pre-consumer food waste-stream materials: fish trimmings, sugar-beet pulp, bakery waste, fruit and vegetable waste, cheese waste, fish feed waste and brewer’s grains and yeast. The nutritional quality of the resulting BSFL meals and frass fertiliser were then analysed. In all cases, the volume of waste was reduced (37–79%) and meals containing high quality protein and lipid sources (44.1 ± 4.57% and 35.4 ± 4.12%, respectively) and frass with an NPK of 4.9-2.6-1.7 were produced. This shows the potential value of BSFL as a bio-convertor for the effective management of food waste.

The Impact

While there is growing recognition of the positive role played by organic farming in the reduction of the negative externalities due to conventional agriculture, there is uncertainty about the effect of the latter on the economic performance of the farms. In this scenario, the present paper aims at investigating the effect of organic farming on technical efficiency in Italian olive farms. A cross-section dataset was analyzed through the stochastic frontier function, where the adoption of organic farming was explicitly modeled. Then, to obtain an unbiased estimate of the impact of organic farming on technical efficiency, a propensity score matching method was implemented. The findings reveal that organic farming increases technical efficiency in Italian olive farms by approximately 10%. The highest impact of organic farming is observed in small farms. As for the propensity to become organic, we found that the production and the direct sales of a higher quality of gross marketable output, as well as the intensity of labor and machines, increase the probability to adopt organic farming. Conversely, farm localization, the availability of family labor, and financial capital discourage conversion to the organic farming system.

Abstract Background/Aims  Fatigue has been reported by young people and professionals alike as a major challenge for people living with juvenile idiopathic arthritis (JIA) . It remains unclear as to how therapeutic interventions impacts on this major symptom. The aim of this review was to determine the current evidence for the effectiveness of therapeutic interventions, non- pharmacological and pharmacological, on improving fatigue in adolescents with JIA. Methods  Three electronic databases (MEDLINE, EMBASE, PsycINFO) were searched from 2000 to Feb 2020; in addition to manual searches. Articles were eligible for inclusion if they (i) were original research papers, (ii) had fatigue as a primary outcome measure (iii) included adolescents (10-25 years) and (iv) were available in the English language. Results  Of the 3,142 records identified, 31 underwent full text assessment and 4 studies were included in the qualitative synthesis including 2 from the Netherlands, 1 Germany, and 1 from Canada. The total number of participants across the 4 studies was 824. Three were randomised controlled trials of nonpharmacological interventions and one was a cohort study from a national drug registry including older adolescents JIA (mean: 19-years). Measurement tools included the Paediatric Quality of life multidimensional fatigue scale, (2 studies), the Checklist for Individual Strength CIS-20 (1 study), a numeric rating scale (1 study). In one study a visual analogue scale for energy level was also utilised. In 2 studies baseline prevalence of fatigue was reported as 60% and 76% respectively. Significant reduction in fatigue was observed in all three nonpharmacological studies. In the registry study, fatigue was noted to be prevalent in spite of the disease being in inactive or minimally active on biologic therapy. In 3 studies the relationship between health-related quality of life and fatigue was highlighted and showed a decreased quality of life in fatigued young people. Conclusion  Fatigue is a significant problem in JIA during adolescence and influences quality of life. Improvements in fatigue with non-pharmacological interventions have been reported. However, at present, data is insufficient to conclusively decide which treatment intervention is most efficacious in treating fatigue in young people with JIA. Fatigue should be considered as an important outcome measure for the management of JIA in future evaluations of interventions. Disclosure  S. Moshtael: None. S. Khanom: None. J.E. McDonagh: None.

Environmental heterogeneity is a central component influencing the virulence and epidemiology of infectious diseases. The number and distribution of susceptible hosts determines disease transmission opportunities, shifting the epidemiological threshold between the spread and fadeout of a disease. Similarly, the presence and diversity of other hosts, pathogens and environmental microbes, may inhibit or accelerate an epidemic. This has important applied implications in farming environments, where high numbers of susceptible hosts are maintained in conditions of minimal environmental heterogeneity. We investigated how the quantity and quality of aquaculture enrichments (few vs. many stones; clean stones vs. stones conditioned in lake water) influenced the severity of infection of a pathogenic bacterium, Flavobacterium columnare, in salmonid fishes. We found that the conditioning of the stones significantly increased host survival in rearing tanks with few stones. A similar effect of increased host survival was also observed with a higher number of unconditioned stones. These results suggest that a simple increase in the heterogeneity of aquaculture environment can significantly reduce the impact of diseases, most likely operating through a reduction in pathogen transmission (stone quantity) and the formation of beneficial microbial communities (stone quality). This supports enriched rearing as an ecological and economic way to prevent bacterial infections with the minimal use of antimicrobials.

Means Of Transmission

The presence of yeasts in milk may cause physical and chemical changes limiting the durability and compromising the quality of the product. Moreover, milk and dairy products contaminated by yeasts may be a potential means of transmission of these microorganisms to man and animals causing several kinds of infections. This study aimed to determine whether different species of yeasts isolated from bovine raw milk had the ability to develop at 37°C and/or under refrigeration temperature. Proteinase and phospholipase activities resulting from these yeasts were also monitored at different temperatures. Five genera of yeasts (Aureobasidium sp., Candida spp., Geotrichum spp., Trichosporon spp. and Rhodotorula spp.) isolated from bovine raw milk samples were evaluated. All strains showed one or a combination of characteristics: growth at 37°C (99·09% of the strains), psychrotrophic behaviour (50·9%), proteinase production (16·81% of the strains at 37°C and 4·09% under refrigeration) and phospholipase production (36·36% of the isolates at 37°C and 10·9% under refrigeration), and all these factors may compromise the quality of the product. Proteinase production was similar for strains incubated at 37°C (16·81% of the isolates) and room temperature (17·27%) but there was less amount of phospholipase-producing strains at room temperature (15·45% of the isolates were positive) when compared with incubation at 37°C (36·36%). Enzymes production at 37°C by yeasts isolated from milk confirmed their pathogenic potential. The refrigeration temperature was found to be most efficient to inhibit enzymes production and consequently ensure better quality of milk. The viability of yeasts and the activity of their enzymes at different temperatures are worrying because this can compromise the quality of dairy products at all stages of production and/or storage, and represent a risk to the consumer.
