More brown hens were on lower-tier wire floors in the dark, while more white hens occupied top tiers. Brown hens laid more eggs outside nests, showed lower incidence of keel fractures, and had better plumage quality than white hens. White hens had higher odds of keel fractures (4.2) than brown hens. Odds of keel fractures were 3.7 and 5.7 times higher at 54 and 72 wk than at 28 wk in all strains (P ≤ 0.05). Occupying the upper tier at night increased odds of keel fractures by 5.4 times. Occupying perches was associated with lower odds of foot lesions and poor plumage quality in all strains across the lay cycle (P ≤ 0.05). Finally, white hens were associated with lower odds of non-nest laying (0.76), whereas higher nest use by brown hens resulted in higher odds of non-nest egg laying (1.56) across the lay cycle (P ≤ 0.05). Distinct strain differences in resource use in an aviary were associated with different risks to hens' production, health, and welfare.In on-farm hatching systems, eggs that have been incubated for 18 D are transported to the broiler farm. After hatching around day 21, the chicks have immediate access to feed and water. Tetrazolium Red in vivo By contrast, traditionally hatched chicks are in early life exposed to dust and pathogens in the hatcher, handling procedures, and transport and remain without feed and water until they have arrived on the farm 1 to 3 D after hatching. We compared welfare and performance of on-farm hatched (OH) and traditionally hatched control (C) Ross 308 broiler chickens from day 0 to 40, housed under semicommercial conditions. The experiment included 3 production cycles in 4 rooms, with each room containing 1 OH and 1 C pen with 1,150 chickens in each pen. Per cycle, C and OH chicks were from the same batch of eggs of 1 parent stock flock. Day-old chick quality was worse for OH than C chickens (hock and navel score; P less then 0.05). On-farm hatched chickens were heavier than C chickens until day 21 of age (P less then 0.05). Total mortality was significantly lower in OH compared with C pens (P less then 0.05). A tendency for lower footpad dermatitis scores was found in OH pens compared with C pens (P less then 0.10), probably because of the dryer litter in OH than C pens (P less then 0.05). No differences between treatments were found in gait, hock burn, cleanliness, and injury scores, and no or only minor, short lasting differences were found in pathology and intestinal histology. In conclusion, the present study showed that on-farm hatching may be beneficial for broiler welfare, as it reduced total mortality and resulted in dryer litter which is known to be beneficial for reducing footpad dermatitis.The objective of present study was to investigate the effects of alpha-lipoic acid (ALA) dietary supplementation on the behavior, physiological and oxidant stress indicators, and bone quality in broilers under high stocking density (HSD) stress. A total of one thousand eight hundred 22-day-old Arbor Acres male broiler chicks were randomly allocated to 18 pens (2.97 × 2.03 m) in 3 groups 14 birds/m2 (NSD, normal stocking density) or 18 birds/m2 (HSD) or 18 birds/m2 plus 300 mg/kg ALA dietary supplement (HSD + ALA, high stocking density + alpha-lipoic acid). Each treatment had 6 replicates, and the experiment lasted 3 wk. The HSD group was significantly lower than the NSD group (P 0.05) in the standing and preening behavior, alkaline phosphatase activity, PTH concentration, H/L ratio, CAT, T-AOC, MDA, SOD, and GSH-Px. These results indicate that the increase of stocking density lowered the bone quality, increased the physiological and oxidative stress indicators, and modified the behavior of broilers, whereas ALA dietary supplementation could counteract the reduction in the performance and physiological responses of broilers under high-density environmental stress.A significant proportion of elderly people suffering from neurodegenerative pathologies are cared for by an informal caregiver. From the earliest stages of the disease, the psychological and behavioural disorders of patients constitute stress and anxiety factors for their caregivers. Mindfulness meditation has proven its usefulness in the management of anxiety. A study proposes caregiver management based on a mindfulness meditation program.The malaise in the gerontology sector can be accounted for and new explanations for caregiver burnout can be proposed. Through a review of the literature, an overview of the issue can be drawn up and a theoretical and clinical reflection can be initiated. After having contextualized the extent of the phenomenon, we will present the plural conceptions of burn out and its origin. A new look will be taken at this syndrome by raising a set of factors potentially involved in the exhaustion of caregivers.Geriatric caregivers are subjected to physically and psychologically demanding situations. A geriatric short-stay service has implemented measures with a unique, creative and dynamic approach. These include participatory management, benevolence and the enhancement of the quality of work.The health emergency linked to Covid-19 has been stressful for staff working in nursing home, and doubly painful for residents faced with the risk of infection and the reality of family separation. We explore in this article some psychological consequences resulting from their experience in the waning health crisis, hoping that the experience gained will allow greater efficiency in the event of a resumption of the pandemic.The hand, a vector of knowledge and understanding of the surrounding world, promotes relationships. For all medico-social professionals, taking care of the hand involves touch, benevolent accompaniment to encourage movement and involvement in the activities of daily life. Touch in the relationship with the elderly person places the occupational therapist in the dynamics of rehabilitation in an interprofessional team. Three facets of touch are described.Compared with other sensory modalities, age-related alterations in taste and smell are less known and less investigated in clinical practice. In fact, the elderly with a loss of smell or taste may not always report it or be aware of it. In addition, the clinical evaluation of taste and smell by specific tests is rarely performed.
