Abstract [en]

The currently most widespread stunning method for pigs is high concentration of carbon dioxide (CO2), but this method is under scrutiny due to animal welfare deficits. One alternative method currently under development with potential to replace CO2 is nitrogen (N2) filled high expansion foam. While N2 does not elicit the same aversive behaviour as CO2, it is currently not known if the high expansion foam itself may be frightening to the pigs. Means to alleviate fear reactions to foam could consist of diverting pigs’ attention using aromas (an odour in combination with taste) of interest to them. The current study aimed to investigate if an added aroma (vanilla aroma) affected pigs’ avoidance and exploratory behaviour when exposed to air-filled high expansion foam in a foam box. The study included 50 pigs (30 females, 20 males) of 14–16 weeks of age, of different crosses between Yorkshire, Hampshire and Duroc. The pigs were randomly assigned to either the treatment with air-filled foam with added aroma or the control treatment with no added aroma, which they were exposed to in a foam box. The results showed that pigs with the aromatised foam expressed significantly more exploration behaviour directed towards the foam and box walls, but not towards the floor or the lid. The aromatised foam also resulted in a higher activity level of the pigs. In contrast to the hypotheses, pigs with aromatised foam expressed more avoidance behaviour, and escape attempts were exclusively observed when pigs were exposed to aromatised foam. Slipping events and frequency of vocalisations did not differ between pigs with and without aroma added to the foam. This study shows that an added aroma (taste and odour in combination) increased pigs’ exploration behaviour towards the foam, and thus could serve as a distraction for the pigs when inside a confined foam box. The results emphasise the importance of taking foam aroma into consideration in the further development of the N2-filled high expansion as a stunning method. The potential anxiety- or stress-reducing effect of any added aroma needs further investigation, and future studies should focus on assessing various types of aromas, and/or odours, as well as different concentrations of the compounds to determine which solution is most efficient in alleviating pig stress and anxiety.

Abstract [sv]

Inledning Fysisk belastning är en av de vanligaste arbetsrelaterade orsakerna till besvär i rörelseorganen, funktionsnedsättningar, och sjukskrivningar. I Sverige beräknas kostnaderna för arbetsrelaterade sjukdomar och olycksfall uppgå till cirka 164 miljarder kronor årligen. Arbetsrelaterade besvär och belastningsskador i övre extremiteten kan uppkomma då kroppen utsätts för repetitiva rörelser, tunga lyft, obekväma arbetsställningar och/eller vibrationer. Trots att riskfaktorerna är kända, arbetar fortfarande alltför många på ett sätt som medför risk för belastningssjukdom. Arbete i häststall kännetecknas av tungt och ensidigt arbete, besvärliga arbetsställningar som ofta utförs i slitna anläggningar med låg mekaniseringsgrad. Studier har visat på hög förekomst av belastningsbesvär hos anställda på ridskolor. Besvären är främst lokaliserade till axlarna, nedre delen av ryggen och nacken. För att kunna identifiera och prioritera relevanta åtgärder, i syfte att minska risken för belastningsskador hos anställda, krävs en riskbedömning av den fysiska belastningen. Metoder för riskbedömning av belastning baseras vanligtvis på självrapportering och observationer. Dessa metoder har dock stora begränsningar. Exempelvis har tillförlitligheten av observationer och andra former av expertbedömningar visat sig vara låg även då de görs av erfarna ergonomer. Att objektivt och kvantitativt kunna mäta belastningen har tidigare varit praktiskt svårt att genomföra, men har nu möjliggjorts med modern teknik. Med en personbunden mätutrustning kan man enkelt mäta den fysiska belastningen under hela arbetsdagar ute på arbetsplatserna. Syfte Syftet med den här pågående studien är dels att öka kunskapen om arbetsställningar och belastning samt relaterade riskfaktorer inom hästsektorn, dels att utvärdera användbarheten av en ny metod med en smart tröja för att mäta arbetsställningar. Med kunskap om arbetsbelastning och arbetets organisering kan effektiva åtgärder, för att minska eller eliminera ohälsosam fysisk exponering, identifieras och implementeras. Detta för att på sikt kunna främja hållbara arbetsmiljöer. Metod Studien är explorativ och genomförs i nära samarbete med den svenska hästnäringen. 8–10 ridskolor, med olika organisering av arbetet och olika mekaniseringsgrad, kommer att ingå i studien. Datainsamlingen, som förväntas pågå under 2024, kommer inkludera objektiva mätningar av arbetsställningar och rörelsehastighet för bål och arm samt av puls, i kombination med observationer av arbetsmoment, intervjuer samt enkäten COPSOQ III, och skattningsskalorna Borgs RPE-skala och Stress-energiformulär. Mätningarna av arbetsställningar och rörelsehastighet kommer att genomföras med hjälp av en smart tröja (Wergonic), en funktionströja med integrerade sensorer som är trådlöst kopplade till en smartphone. Systemet kan med hjälp av algoritmer och vetenskapligt framtagna rekommendationer ge en riskbedömning för en hel arbetsdag. Resultat Projektet förväntas öka kunskapen om riskerna för belastning, hur exponeringen ser ut över arbetsdagen samt vilka arbetsmoment som innebär högst risk för ridskoleanställda. Vidare väntas belastningen kunna relateras till de anställdas upplevda arbetsförmåga, arbetstempo och fysiska ansträngning. Resultatet bör därmed kunna ge indikationer på samband mellan den organisatoriska och sociala arbetsmiljön och den fysiska arbetsmiljön. Utifrån resultaten kan åtgärder för att förbättra arbetsmiljön identifieras och på sikt bidra till bättre hälsa och hållbarhet inom hästrelaterade yrken.

Abstract [en]

The changing climate, with higher temperatures, is challenging pigs’ abilities to lose metabolic heat.This study was conducted during two summers (2022 and 2023) on a commercial pig farm in Sweden,latitude 59.7°N, using a change over design. In one pig unit the solid floorings, in partly slatted pens(8.96 m2, solid lying area 71% and slatted dunging area 29%), were cooled whilst the solid flooringsin the adjacent pig unit had no cooling. Each pig unit had 38 pens with 9-10 pigs/pen (LYxH, mixedsexes, ~35-115 kg, undocked). Cooling was conducted by circulating chilled water (~11℃) in thewaterborne pipes casted in the concrete. Concentrations of ammonia (NH3) and carbon dioxide(CO2) were measured with a photoacoustic gas monitor 1512 and a multipoint sampler 1409(Lumasense Technologies A/S, Denmark) above four focal pens/pig unit, in addition to samplingpoints by one air inlet and by one exhaust fan in each unit. Temperature and relative humidity werecontinuously registered with loggers (Gemini Data Loggers Ltd., UK) mounted next to the samplingpoints of NH3 and CO2, and close to the lying area in the focal pens. Pig hygiene was assessedaccording to a protocol developed based on literature. Statistical analyses were performed usingPROC GLM in SAS version 9.4. Preliminary results show that the proportion of pigs with the mildesthygiene score (<20 % of the body dirty) were higher in cooled compared to control pens (on average44.6±1.30 vs. 28.8±1.03 % of pigs in the pen (LSM±SE), p<0.001). In accordance, the correspondingproportion of pigs with the most severe hygiene score (>50 % of the body dirty) were lower in cooledpens compared to control (on average 31.8±1.37 vs. 47.9±1.37 % of pigs in the pen (LSM±SE),p<0.001). In addition, the results show lower levels of both NH3 and CO2 with floor coolingcompared to the control (2.9±0.03 vs 4.0±0.03 ppm NH3 and 1345±3.9 vs 1376±3.9 ppm CO2(LSM±SE), p<0.001 for both). The average temperature was lower in the unit with cooled floortreatment compared to control, both in the sample points above the pen (20.7±0.03 vs. 21.2±0.03 ºC(LSM±SE), p<0.001) and closer to the floor in the lying area (26.3±0.06 vs. 27.7±0.07 ºC (LSM±SE),p<0.001) while there were no significant differences in relative humidity between treatments. Theresults indicate a favourable effect of floor cooling on pig hygiene, thermal and gaseousenvironment.

Abstract [en]

A well-functioning systematic occupational safety and health management is beneficial for both individuals and organizations, and employee motivation seems to be crucial for positive outcomes. Occupational safety and health issues are a major concern for the Swedish equine sector since the work environment in horse stables is known to be characterized by low mechanization, high physical workloads, and high injury risks. The purpose of this study was to gain an increased understanding of how systematic occupational safety and health management is performed and which factors that influence motivation for occupational safety and health improvements in the Swedish equine sector. An explanatory sequential mixed-methods study, based on quantitative data from questionnaires and qualitative data from semi-structured interviews, was conducted. Various statistical analyses were performed to obtain quantitative data and an abductive applied thematic analysis was applied for the qualitative data. The results indicate that both intrinsic motivators, i.e. attitudes, values, and influence, as well as contextual factors such as motivational management, occupational culture, and workplace resources, influence compliance in systematic occupational safety and health management and participation in occupational safety and health improvements, which in turn affect workplace outcomes regarding safety and health. The positive relationship found between an implemented and functioning systematic occupational safety and health management and employee motivation for occupational safety and health improvements indicate the importance of employee involvement and participation. Understanding the motivational factors for occupational safety and health improvements from an employee perspective is an important step to creating healthy and sustainable workplaces.

Abstract [en]

The common method of stunning pigs using high concentration carbon dioxide prior to slaughter poses an animal welfare issue, as the gas is aversive. Proof of concept for using nitrogen gas encapsulated in high-expansion foam as an alternative non-aversive method for stunning pigs has recently been presented. However, the individually tested pigs showed distress-related responses to foam exposure, regardless of whether it was nitrogen- or air-filled. This study examined the effect of companionship from a familiar or unfamiliar pig on behaviours in 72 nine-weeks old pigs during exposure to air-filled foam. Escape attempts were observed by 75% of solitary pigs, 42% of pigs with unfamiliar conspecifics, and 33% of pigs with familiar conspecifics. Familiar pig pairs clearly preferred social contact during foam exposure, whereas this was not as clear in unfamiliar pig pairs, and their motivation for social contact could have multiple explanations. The results from this study highlight the importance of contact with conspecifics when studying animal welfare and suggest that familiarity between pigs is important for social support, thus emphasizing the importance of maintaining social groups to reduce distress in pigs at slaughter. © 2023 by the authors.
