Effect of housing on rubber slat mats during pregnancy on the behaviour and welfare of sows in farrowing crates

peer-reviewedThe aim of this study was to evaluate the effect of flooring type during gestation, lameness and limb lesion scores on welfare and behaviour of sows in farrowing crates. Sixty sows group-housed during gestation in pens with solid concrete floored feeding stalls and a concrete, fully slatted group area either uncovered (CON; n = 30) or covered with 10 mm thick rubber slat mats (RUB; n = 30) were transferred to the farrowing crate at 110d of gestation (-5d). Lameness was scored on -5d and at weaning (28 d postfarrowing). Limb lesions were scored on -5d, 24 h later (-4d), 3 to 5 days post farrowing and at weaning (i.e., day 28 post farrowing). Sows were video recorded for 24 h on -5d, after the last piglet was born (FARROW) and prior to weaning. Videos were sampled every 10 min and an index of the proportion of time spent in different postures (standing [S], ventral [VL] and lateral lying [LL] and total lying) and number of postural changes was calculated. Median scores were calculated for limb lesions and classified as ≤ median or > median. Postural data were tested for normality and analysed using mixed model equations methodology. Flooring during gestation did not affect any of the variables recorded in this study. However, RUB sows tended to make more postural changes than CON sows (P = 0.10). Sows with swelling scores > median spent more time LL (68.9 vs. 63.1 ± 2.19%; P < 0.05) and less time VL (19.9 vs. 25.8 ± 2.27%; P < 0.05) than sows with swelling scores ≤ median. Time spent S and VL decreased and LL increased at FARROW compared to -5d and prior to weaning (P < 0.01). We found no effect of flooring type during gestation on welfare and behaviour in the farrowing crate. Factors such as limb lesions and adaptation to confinement (i.e., time spent inside the farrowing crate) appeared to have a greater influence on sow welfare and behaviour in farrowing crates than the flooring on which they were housed during gestation.This work was administered by Teagasc’s Walsh Fellowship Scheme via funding from Enterprise Ireland and EasyFix™ Rubber Products

International Obligation to Prosecute Human Rights Violators: Spain\u27s Jurisdiction over Argentine Dirty War Participants

Many nations view the obligation of protecting human rights as worthy of relaxing the traditional deference to State sovereignty. They believe interference is necessary to prevent and punish human rights violators. In the 1970s and 8 b. Argentina was subject to an intense military rule. Disappearances, torture and extra-legal executions were the regime\u27s tools of oppression, and despite Argentina\u27s claim that those guilty of human rights violations were properly dealt with, the new democracy\u27s measures were insufficient to conform to Argentina\u27s legal obligations. Argentina\u27s inaction constitutes a violation of Argentine and international law. Hundreds of Spanish nationals were victims of the military regime in Argentina. This note argues that under Spanish, international treaty and customary law, Spain is justified, and in fact compelled, to try the Argentine war criminals in its national courts

The Relationship Between Insomnia, Sleep Continuity Disturbance, Sleep-related Daytime Dysfunction, Problem Endorsement, and Aging in a Community-based Sample

Although older adults experience greater difficulty initiating sleep, maintaining sleep, or waking up earlier than intended, they are less likely to report that they perceive this to be a problem. The discordance between sleep disorder symptoms and the reported perception that they are troubling is unusually prevalent among older adults. This may be problematic, in that individuals who do not perceive their sleep continuity disturbances (SCDs; difficulty falling asleep, staying asleep, or waking up earlier than intended) to be problems are less likely to seek treatment. Untreated SCD has been shown to be a risk factor for the development or exacerbation of multiple medical and psychiatric disorders such as cardiovascular disease, stroke, dementia, and depression. This study aimed to identify the relationship between age, SCD, sleep-related daytime dysfunction, and the perception that these symptoms are problematic. The study utilized a cross-sectional group comparison approach to assess for age differences in relation to SCD, sleep-related daytime dysfunction, and percent problem endorsement in an archival, community dataset comprised of individuals between 18 and 89 years of age, with sleep complaints. The results indicated that, as expected, SCD worsens with age (except sleep latency); sleep-related daytime dysfunction did not worsen with age except for concentration; and, contrary to expectation, problem endorsement increased with age (except for sleep latency). Findings illustrate the importance of comprehensive sleep assessments, preferably with the inclusion of the question: Is this a problem

University Policies on the Dangers of Spyware Apps

Despite the comprehensive nature of many universities’ cyberstalking policies, the rapid rate of technological growth has created legal loopholes. The growing popularity of unregulated spyware apps--typically marketed towards employers and parents, has fallen into the hands of abusers, creating an innovative outlet to easily stalk victims. Domestic violence shelters are increasingly receiving young victims who have been stalked by spyware apps. Thus, by analyzing the cyberstalking policies of three top universities, this study will seek to discover the effectiveness of fighting against those perpetuating violence through spyware apps. Finally, in comparison with the three schools, Northern Illinois University’s policy will be analyzed.B.A. (Bachelor of Arts

Cura Personalis as Institutional Practice

Founded by Loyola University Chicago in 2015, Arrupe College is a two-year program that continues the Jesuit tradition of offering a rigorous liberal arts education to a diverse population, many of whom are the first in their families to pursue higher education. Using an innovative model that ensures affordability while providing care for the whole person—intellectually, morally, and spiritually—Arrupe prepares its graduates to continue on to a bachelor’s program or move into meaningful employment. From the beginning, cura personalis has been a priority at this new institution. In this article, drawing on their experience as faculty members and administrators at Arrupe College, Julia Bninski and Jennifer Boyle argue for expanding the definition of cura personalis to include not only individual decisions and behavior, but also institutional policies and procedures

Do weaner pigs need in-feed antibiotics to ensure good health and welfare?

peer-reviewedThis study was part of the WELPIG project which was funded from internal Teagasc funds. During the writing of this paper JACD’s position was funded by the Department of Agriculture Food and the Marine under the Research Stimulus Fund (PathSurvPigs 14/S/832) as part of the National Development PlanAntibiotics (AB) are used in intensive pig production systems to control infectious diseases and they are suspected to be a major source of antibiotic resistance. Following the ban on AB use as growth promoters in the EU, their prophylactic use in-feed is now under review. The aim of this study was to evaluate the effect of removing prophylactic in-feed AB on pig health and welfare indicators. Every Monday for six weeks, a subset of 70 pigs were weaned, tagged and sorted into two groups of 35 pigs according to weight (9.2 ± 0.6 kg). AB were removed from the diet of one group (NO, n=6) and maintained in the other group (AB, n=6) for nine weeks. Ten focal pigs were chosen per group. After c. five weeks each group was split into two pens of c.17 pigs for the following 4 weeks. Data were recorded weekly. Skin, tail, ear, flank and limb lesions of focal pigs were scored according to severity. The number of animals per group affected by health deviations was also recorded. The number of fights and harmful behaviours (ear, tail bites) per group was counted during 3×5min observations once per week. Data were analysed using mixed model equations and binomial logistic regression. At group level, AB pigs were more likely to have tail (OR=1.70; P=0.05) but less likely to have ear lesions than NO pigs (OR=0.46; P<0.05). The number of ear bites (21.4±2.15 vs. 17.3±1.61; P<0.05) and fights (6.91±0.91 vs. 5.58±0.72; P=0.09) was higher in AB than in NO pigs. There was no effect of treatment on health deviations and the frequency of these was low. Removing AB from the feed of weaner pigs had minimal effects on health and welfare indicators

Influence of High Energy Diet and Polygenic Predisposition for Obesity on Postpartum Health in Rat Dams

It is estimated that 30% of pregnant women worldwide are overweight or obese, leading to adverse health effects for both mother and child. Women with obesity during pregnancy are at higher risk for developing both metabolic and mental disorders, such as diabetes and depression. Numerous studies have used rodent models of maternal obesity to understand its consequences on the offspring, yet characterization of changes in the dams is rare, and most rodent models rely solely on a high fat diet to induce maternal obesity, without regarding genetic propensity for obesity. Here we present the influence of both peripartum high energy diet (HE) and obesity-proneness on maternal health using selectively bred diet-resistant (DR) and diet-induced obese (DIO) rat dams. Outbred Sprague-Dawley rats were challenged with HE diet prior to mating and bred according to their propensity to gain weight. The original outbred breeding dams (F0) were maintained on low-fat chow during pregnancy and lactation. By comparison, the F1 dams consuming HE diet during pregnancy and lactation displayed higher gestational body weight gain (P &lt; 0.01), and HE diet caused increased meal size and reduced meal frequency (P &lt; 0.001). Sensitivity to the hormone amylin was preserved during pregnancy, regardless of diet. After several rounds of selective breeding, DIO and DR dams from generation F3 were provided chow or HE during pregnancy and lactation and assessed for their postpartum physiology and behaviors. We observed strong diet and phenotype effects on gestational weight gain, with DIO-HE dams gaining 119% more weight than DR-chow (P &lt; 0.001). A high-resolution analysis of maternal behaviors did not detect main effects of diet or phenotype, but a subset of DIO dams showed delayed nursing behavior (P &lt; 0.05). In generation F6/F7 dams, effects on gestational weight gain persisted (P &lt; 0.01), and we observed a main effect of phenotype during a sucrose preference test (P &lt; 0.05), with DIO-chow dams showing lower sucrose preference than DR controls (P &lt; 0.05). Both DIO and DR dams consuming HE diet had hepatic steatosis (P &lt; 0.001) and exhibited reduced leptin sensitivity in the arcuate nucleus (P &lt; 0.001). These data demonstrate that both diet and genetic obesity-proneness have consequences on maternal health

Prevalence of welfare outcomes in the weaner and finisher stages of the production cycle on 31 Irish pig farms

peer-reviewedBackground Knowledge on the most prevalent welfare problems for pigs in different production stages is required to improve herd management plans. Thirty-one farrow-to-finish pig farms were visited between July and November 2015 to assess the welfare of pigs using the multicriteria approach of the Welfare Quality® protocol. On each farm, 6 pens were selected using proportionate stratified sampling in the first weaner (S1, 4 to 8 wks), second weaner (S2, 8 to 13 wks) and finisher stage (S3, 13 to 23 wks), excluding hospital pens. Each pen was observed for 10 min and the number of pigs affected by different welfare outcomes was recorded. The percentage of pigs affected was calculated and ranked to identify the most prevalent outcomes within each production stage. Differences between production stages were analysed using generalised linear mixed models for binomial data with pen within stage and farm as a random effect. Results Tail and ear lesions showed the highest prevalence; however, large variation was observed between farms. In S1 the most prevalent welfare outcomes (presented as median prevalence) were poor body condition (4.4%), lethargic pigs (1.5%), scouring (20.3% of pens) and huddling (3.7%). In S2 and S3 outcomes related to injurious behaviour (tail lesions: 5.9% [S2] and 10.5% [S3], ear lesions: 9.1% [S2] and 3.3% [S3], and flank lesions: 0.4% [S2] and 1.3% [S3]), lameness (0.8% [S2] and 1.1% [S3]), bursitis (3.9% [S2] and 7.5% [S3]) and hernias (1.6% [S2] and 1.8% [S3]) were more prevalent. Conclusions A large variation was observed for the recorded welfare outcomes corresponding to the different challenges pigs experience during the different stages of production on commercial pig farms. The prevalence of pigs affected by lesions caused by injurious behavior is a cause for concern and requires a collaborative approach to identify appropriate intervention strategies. This information could be used to further investigate appropriate benchmark values for different welfare outcomes that would assist the pig industry to develop appropriate health and welfare management plans to minimise welfare problems. At herd level such plans should include information on aspects of intervention, treatment, and the management of hospital pens as well as euthanasia.This study was part of the PIGWELFIND project funded by the Research Stimulus Fund (11/S/107) of the Irish Department of Agriculture, Food and Marine under the National Development Plan (2007–2013).

Ear, tail and skin lesions vary according to different production flows in a farrow-to-finish pig farm

peer-reviewedBackground Pig performance and risk of disease are associated with production flow. Given the link between health and welfare, it is likely that animal welfare indicators are also associated with production flow. This study investigated the association between production flow and tail, ear and skin lesions on a farm with a purported ‘all-in/all-out’ policy. This was an observational study whereby pigs were managed according to routine farm practice. A total of 1,016 pigs born within 1 week from the same batch were followed through the production stages and the presence or absence of welfare indicators was recorded at 4, 7, 9, 12, 16 and 24 weeks of age. Three production flows were retrospectively identified: flow 1 = ‘normal’ pigs that advanced through the production stages together ‘on time’, flow 2 = pigs delayed from advancing from the 1st to the 2nd nursery stage by 1 week and flow 3 = pigs delayed from advancing through the production stages by > 1 week. A nested case control design was applied by matching pigs by sow parity, number of born alive and birth weight. Results The presence of ear lesions was 4.5 less likely in pigs in flow 2 and 2.9 times less likely in pigs in flow 3 (P < 0.001) compared to pigs in flow 1. Pigs in flow 3 were 2.2 more likely to have tail and 1.6 times more likely to have ear lesions (P < 0.001) compared to pigs in flow 2. Pigs in flow 2 were less likely to have tail lesions compared with pigs in flow 1 (P < 0.05). Differences between production flows for the risk of skin lesions varied according to age (P < 0.05). Conclusion All production flows were associated with a high risk of lesions which raises concerns for pig welfare. However, risks for ear, tail and skin lesions varied according to each production flow likely due to the specific management practices inherent to each flow. Results from this study could be used to modify existing management practices, thus leading to improvements in animal welfare and possibly performance in intensive pig systems

The BTC40 Survey for Quasars at 4.8 < z < 6

The BTC40 Survey for high-redshift quasars is a multicolor search using images obtained with the Big Throughput Camera (BTC) on the CTIO 4-m telescope in V, I, and z filters to search for quasars at redshifts of 4.8 < z < 6. The survey covers 40 sq. deg. in B, V, & I and 36 sq. deg. in z. Limiting magnitudes (3 sigma) reach to V = 24.6, I = 22.9 and z = 22.9. We used the (V-I) vs. (I-z) two-color diagram to select high-redshift quasar candidates from the objects classified as point sources in the imaging data. Follow-up spectroscopy with the AAT and CTIO 4-m telescopes of candidates having I < 21.5 has yielded two quasars with redshifts of z = 4.6 and z = 4.8 as well as four emission line galaxies with z = 0.6. Fainter candidates have been identified down to I = 22 for future spectroscopy on 8-m class telescopes.Comment: 27 pages, 8 figures; Accepted for publication in the Astronomical Journa
