- The behavior of rooting and digging is highly motivated in the pig. The motivation to perform this exploratory behavior is not reduced even after the dietary requirement has been fulfilled through feeding. The aim of this study was to identify the minimal amounts of straw needed to satisfy pig motivation for manipulation and reduce to a minimum the manipulating behavior of pigs directed toward pen mates. To determine the minimal amount of straw needed for conventional growing-finishing pigs, a study using 168 pigs provided with 7 different amounts of straw (20, 40, 60, 80, 100, 200 or 300 grams/ pig/ day) was performed. The straw was provided either once or four times per day. Behavior observations were made using focal animal sampling and continuous recording for one hour between 9 and 10 am and between 3 and 4 pm. The time spent by the pigs manipulating straw increased over 10% ranging up to 27% in all the pens receiving over 200g of straw per day compared to the range from 4-22% in pens receiving 20-100g of straw. Meanwhile, the time spent in redirected behavior decreased below 5% in all the pens receiving over 200g of straw per day. No significant differences were found when comparing pens provided with straw once or four times per day.

- Halm har tydliga positiva effekter för slaktgrisars välbefinnande. Informationen, om vilken mängd av halm som krävs för att uppnå dessa positiva effekter, är dock bristfällig. Målsättningen med det utförda projektet var att få fram underlag kring vilka halmmängder som bör ges till slaktgrisar i konventionella inhysningssystem. Totalt ingick tre slaktgrisomgångar med 14 boxar per omgång. Sju olika halmmängder (20, 40, 60, 80, 100, 200 och 300 gram/slaktgris/dag), som tilldelades som en (kl. 10.00) alternativt fyra givor (kl. 10.00, 12.00, 14.00 och 16.00), jämfördes. Grisar som fick 200 eller 300 gram halm/gris/dag spenderade mer tid med att manipulera halm än de grisar som fick 20-100 gram halm/gris/dag. Grisar som fick 20 - 100 gram halm/gris/dag visade mer omriktat beteende än grisar som fick 200 eller 300 gram halm/gris/dag. "Gränsgivan", då man minskar de negativa beteendena, tycktes i denna studie ligga vid mellan 100 och 200 gram halm/gris/dag. Vid högre halmgivor registrerades inga extra fördelar avseende de negativa beteendena medan förekomsten av undersökande beteenden ökade. Vid små halmgivor visade de grisar, som fick sin halm uppdelad på fyra tillfällen, mer omriktat beteende än grisar som fick samma mängd vid bara ett tillfälle. Slutsatsen av studien är att mängden halm bör ligga mellan 100 - 200 gram/gris/dag om man enbart tar hänsyn till negativa beteenden hos grisen, men minst 300 g om man tar hänsyn till grisens behov av att undersöka sin omgivning.

Metabolic Syndrome Is Associated With Poor Cognition : A Population-Based Study of 70-Year-Old Adults Without Dementia

- Background: Individual conditions of metabolic syndrome (MetS) have been related to dementia; however, their combined impact on the preclinical stage is unknown. We investigated the associations between MetS and domain-specific cognitive function as well as the role of sociodemographic, cardiovascular, and genetic factors.Methods: Within the Gothenburg H70 Birth Cohort Study-Birth cohort 1944, 1131 dementia-free participants (aged 70 years) were examined during 2014-2016. MetS (central obesity plus at least 2 factors [reduced HD11.-cholesterol, elevated triglycerides, blood pressure, or blood glucose]) was identified according to the International Diabetes Federation criteria. Five cognitive domains (memory, attention/perceptual speed, executive function, verbal fluency, visuospatial abilities) were generated after z-standardizing raw scores from 10 neuropsychological tests. Education, heart disease, claudication (indicating peripheral atherosclerosis), and apolipoprotein genotype were ascertained by trained staff. Data were analyzed with linear regression models.Results: Overall, 618 participants (55%) had MetS. In multiadjusted linear regressions, MetS was related to poorer performance in attention/ perceptual speed (beta -0.14 [95% CI -0.25, -0.02]), executive function (beta -0.12 [95% CI -0.23, -0.01]), and verbal fluency (beta -0.19 [95% CI -0.30, -0.08]). These associations were present only among individuals who did not carry any APOE-epsilon 4 allele or were highly educated. However, among those with MetS, high education was related to better cognitive performance. MetS together with comorbid heart disease or claudication was associated with even worse cognitive performance than each alone.Conclusions: MetS is associated with poor attention/perceptual speed, executive function, and verbal fluency performance. Education, apolipoprotein E-epsilon 4 allele, and comorbid cardiovascular disease influenced the observed associations.
