The Impact

Automatic milking systems (AMS) are a low-labour alternative to conventional parlours, with previous studies demonstrating that cows vary in their ability to cope with the change to AMS. Cortisol expression can be combined with other measures to assess stress: saliva and hair have the advantage of requiring minimally invasive sampling. No work has investigated the long-term impact of introduction of AMS. The aims of the study were to assess short-term and chronic stress associated with a change in milking system by measuring salivary and hair cortisol levels and to assess the impact on health and production parameters. Cows from one farm changing their milking system were recruited to the study and sampled for saliva (n = 10) and hair (n = 12) before and after installation. Cortisol levels were measured using a salivary cortisol enzyme immunoassay kit. Body condition, lameness and milk parameters of the whole herd were regularly assessed. Salivary cortisol showed no diurnal pattern but was affected by lameness and gestation. Non-lame cows showed a reduction in salivary cortisol after AMS introduction (p < 0.001). Hair cortisol levels increased after AMS, but it was unclear if this change was seasonal. Milk yield increased by 13% and somatic cell count reduced by 28%. Body condition score was consistently good, but lameness remained high throughout the study. Production values alone do not represent high welfare. The high lameness and associated cortisol levels suggest that cow stress requires consideration when changing milking systems.

AbstractThe intensity and the magnitude of saliva cortisol responses were investigated during the first 48 h following birth in newborn dairy calves which underwent normal (eutocic, EUT, n = 88) and difficult (dystocic, DYS, n = 70) calvings. The effects of parity and body condition of the dam, the duration of parturition, the time spent licking the calf, the sex and birth weight of the calf were also analyzed. Neonatal salivary cortisol concentrations were influenced neither by factors related to the dam (parity, body condition) nor the calf (sex, birth weight). The duration of parturition and the time spent licking the calf also had no effect on salivary cortisol levels. Salivary cortisol concentrations increased rapidly after delivery in both groups to reach their peak levels at 45 and 60 min after delivery in EUT and DYS calves, respectively supporting that the birth process means considerable stress for calves and the immediate postnatal period also appears to be stressful for newborn calves. DYS calves exhibited higher salivary cortisol concentrations compared to EUT ones for 0 (P = 0.022), 15 (P = 0.016), 30 (P = 0.007), 45 (P = 0.003), 60 (P = 0.001) and 120 min (P = 0.001), and for 24 h (P = 0.040), respectively. Peak levels of salivary cortisol and the cortisol release into saliva calculated as AUC were higher in DYS than in EUT calves for the 48-h of the sampling period (P = 0.009 and P = 0.003, respectively). The greater magnitude of saliva cortisol levels in DYS calves compared to EUT ones suggest that difficult parturition means severe stress for bovine neonates and salivary cortisol could be an opportunity for non-invasive assessment of stress during the early neonatal period in cattle.

Abstract This research communication describes the relationship between the occurrence of lameness and body condition score (BCS) in a sample of 288 cows from a single farm that were repeatedly scored in the course of 9 months while controlling for confounding variables. The relationship between BCS and lameness was evaluated using generalised linear mixed-effects models. It was found that the proportion of lame cows was higher with decreasing but also with increasing BCS, increased with lactation number and decreased with time since the last claw trimming. This is likely to reflect the importance of sufficient body condition in the prevention of lameness but also raises the question of the impact of overcondition on lameness and the influence of claw trimming events on the assessment of lameness. A stronger focus on BCS might allow improved management of lameness that is still one of the major problems in housed cows.

Although mental disorders are common among university students, the majority of students with mental health issues do not seek out treatment during their academic life. The aim of this study was to evaluate the effects of a novel group approach- choir singing, and its potential impact on stress, via salivary cortisol levels and self-reported stress levels in university students during 4 sessions of choir singing. It was based on a quasi-experimental research conducted with 25 Brazilian university students. Each choir singing session lasted 60 minutes. A question was asked before and after the intervention: what is the level of your stress? Salivary cortisol was collected before and after the intervention. After the choir singing intervention, there was  a statistically significant reduction in self-reported stress (p<0.0001) and salivary cortisol levels (p<0.0001). This research suggests that choir singing can reduce the self-reported stress of university students after 4 weeks of follow-up with ∆= 45.83% and salivary cortisol levels in the first week with ∆= 3.57%.

The objective of this study was to confirm the relationship among body condition score at the time around parturition, milk yield in subsequent lactation, reproductive efficiency and BCS development in Czech Fleckvieh dairy cows. The BCS and milk yield were measured once a month and the cows were divided into groups according to their BCS before and after calving. Next, data from the database of cattle reproduction of the Czech Fleckvieh herd book were used. The dataset was analyzed by multifactorial analysis of variance using procedures COOR and GLM of the statistical program SAS. Cows with lower BCS in the 1<sup>st</sup> month after calving showed an increase in both milk yield and fat and protein corrected milk (FPCM) yield. No significant relationship was found between the BCS level before calving and subsequent milk yield. The body condition level in the last month before parturition influenced its subsequent decrease in the first phase of lactation. The group of cows with the highest BCS level before calving retained a high BCS level in the first five months of lactation. Adequately, the group of cows with the lowest BCS in the first month of lactation had the lowest BCS in the next four months. BCS before calving was not related to reproduction indicators, but the significant effect of BCS in the 1<sup>st</sup> month after calving on the length of calving to the first service interval was confirmed. The group of cows with BCS > 3.5 in the 1<sup>st</sup> month after calving had the most favourable reproduction indicators, also when the milk yield level was taken into account.

The purpose of this retrospective study was to evaluate the relationship between occlusal and clinical parameters and the need for incisor shortening in horses. It was based on the retrospective analysis of the dental charts of 75 confined horses. Body condition score, shape of incisors, presence of dysmastication, excursion to molar contact (EMC) distance before and after cheek teeth occlusal adjustment were evaluated. History of difficult to riding, dysmastication and digestive problems was also considered. The initial measurement of lateral excursion to molar contact (EMC) revealed incisor occlusal surface abnormalities in 45 (60%) horses and long incisors (EMC>15mm) in five (6.6%) horses. Considering clinical examination and history data the need for reduction of incisor length was significant when EMC exceeded 15mm (P<0.0001) and when based on dental shape, clinical history of dysmastication and/or digestive problems or body condition score was also significant (P<0.05). In confined horses, the decision to shorten and align the incisor teeth should be based on observation and history of dysmastication and digestive problems, body condition score, incisors shape and EMC distance. The need for incisor reduction should be determined before dental intervention and reassessed following cheek teeth oclusal adjustment

Management and production characteristics impact conception rate to first service (CR1S) in small-scale dairy farms, but the impact of body condition score (BCS) and milk production levels on cows’ fertility is unknown. Our objective is to determine the effect of BCS and milk production on CR1S in small-scale dairy farms of western Mexico. Logistic regression models are used to determine the effect of BCS (at calving and first service), 60-d and 305-d milk production, protein and fat production, lactation number, and days at first service on CR1S. BCS at calving does not affect CR1S in cows with three or more lactations (39.5%; p > 0.1). However, first-lactation cows with BCS < 3.0 at calving and second lactation cows with BCS ≤ 2.5 at calving have higher CR1S (63.2 and 67.9%, respectively; p < 0.1). This result is perhaps due to reduced milk production, which leads to lower metabolic stress. BCS ≤ 2.5 at calving is associated (p < 0.05) with a reduced milk yield, explaining partially the observed higher CR1S in these groups. Cows with BCS ≤ 2.5 at first service in the higher quartile of 60-d milk production (≥ 28kg/day) show lower CR1S (23.9 and 51.1%, respectively; p < 0.01). In conclusion, BCS at calving and at first service, 60-d milk production, and lactation number are factors associated with CR1S.

Immediately before and after participation in a written final examination, 11 graduate students rated their self-perceived stress and provided saliva samples for cortisol assay. Students rated stress higher before the examination, and these ratings were associated with increased salivary cortisol. Students who reported higher stress and had higher cortisol levels before the examination tended to have significantly lower examination scores.

ObjectiveThe aim of the study was to assess the impact of several psychological and/or biological variables in the recovery from surgery.MethodsThe selected sample was composed of 42 patients (age range: 25–70) admited for surgical treatment to a University Hospital. The patients who presented impaired cognitive functioning were excluded from the study. Prior to surgical intervention (48 to 72 hours), patients were administered the Family Adaptability and Cohesion Evaluation Scale (FACES-II). Salivary cortisol was measured 24 hours before surgery. Following surgical intervention, recovery was coded as “good” or “poor” accordingly to Moix et al.’s criteria (1995). Dietary intake, resting and sleeping time, fever, perceived pain and surgery-related complications were assessed on a daily basis.ResultsSignificant relationships between better recovery, family cohesion and salivary cortisol level were found. The patients with lower scores in the cohesion dimension of the FACES-II and higher cortisol levels had more complications during the recovery phase (F = 10.96, p = 0.006).ConclusionsOur results suggest that social support (family cohesion) and the activity of the hypothalamus-pituitary-adrenal axis (cortisol levels) can have a significant influence on postoperatory recovery. Taking these data into account, it would be suitable to assess psychopathology and social support in patients waiting for surgically interventions.

Objectives: The objective of the study was to assess the behavioral effects and the changes in the anxiety level of children after intranasal and sublingual midazolam sedation using Venham's clinical anxiety scale and salivary cortisol level. Study Design: Twenty children aged 3 to 7 years were randomly assigned to Group A (n=10) intranasal or Group B (n=10) sublingual midazolam (0.2mg/kg) sedation. The anxiety levels at various time periods were assessed using Venham clinical anxiety scale and corresponding changes in salivary cortisol levels were assessed before and after the drug administration. The anxiety levels were assessed independently by two pediatric dentists from recorded videos. Wilcoxon signed rank test and Mann Whitney U test were used for statistical analysis using SPSS version 19.0.Results: There was a significant decrease in anxiety level from baseline to 20 minutes after drug administration in group A (p=0.004) and group B (p=0.003). There was no significant change in salivary cortisol levels before and after the drug administration in group A (p=0.07) and group B (p=0.38). Conclusions: Both intranasal and sublingual administration of midazolam was equally effective in reducing the child's anxiety. However, there was no significant difference in the salivary cortisol levels in both groups.

The Impact

The self-help industry generates billions of dollars yearly in North America. Despite the popularity of this movement, there has been surprisingly little research assessing the characteristics of self-help books consumers, and whether this consumption is associated with physiological and/or psychological markers of stress. The goal of this pilot study was to perform the first psychoneuroendocrine analysis of consumers of self-help books in comparison to nonconsumers. We tested diurnal and reactive salivary cortisol levels, personality, and depressive symptoms in 32 consumers and nonconsumers of self-help books. In an explorative secondary analysis, we also split consumers of self-help books as a function of their preference for problem-focusedversusgrowth-oriented self-help books. The results showed that while consumers of growth-oriented self-help books presented increased cortisol reactivity to a psychosocial stressor compared to other groups, consumers of problem-focused self-help books presented higher depressive symptomatology. The results of this pilot study show that consumers with preference for either problem-focused or growth-oriented self-help books present different physiological and psychological markers of stress when compared to nonconsumers of self-help books. This preliminary study underlines the need for additional research on this issue in order to determine the impact the self-help book industry may have on consumers’ stress.
