The present study aimed to investigate the impact of adding two doses of a commercial probiotic on productive performance, ruminal and fecal microbiome in growing lambs. Forty-two Texel or Ile de France crossbred lambs aged 86.9 ± 8.0 days (body weight: 27.4 ± 3.7 kg) were distributed into three groups: basal diet without probiotic supplementation (CG); basal diet + 1 g/animal/day of probiotic (GP1) and basal diet + 5 g/animal/day of probiotic (GP5). The experimental period was 84 days. The weight was evaluated weekly and dry matter intake (DMI) and leftovers were measured daily. At the end of the experiment, lambs were slaughtered. Feces and rumen fluid were collected for microbiome analysis and rumen fragments for histological evaluation. The use of probiotics did not affect weight gain, but GP1 showed a higher silage and DMI intake than CG (p < 0.001). The CG had a greater thickness of keratinized epithelium and stratum corneum (< 0.001) than GP1 and GP5, and greater total papilla width (p = 0.039) than GP1. There was no difference in the general abundance in the rumen and fecal microbiomes. GP5 had a higher proportion of Azoarcus and Dialister taxa in the rumen fluid (p = 0.012 and p = 0.017, respectively) and higher proportion of Treponema and Fibrobacter taxa in the fecal microbiome (p = 0.015 and p = 0.026, respectively), whereas CG had a higher proportion of Anaeroplasma than the other groups (p = 0.032). These results demonstrated the benefits of probiotics for ruminal epithelium protection and microbial diversity. However, there was no effect on performance parameters.

The aim of this work was to quantify the postures and to assess the musculoskeletal disorders (MSDs) risk in physiotherapists repeating a manual lymphatic drainage (MLD) over a three-month period. The underlying hypothesis was that there would be Generic Postures (GP) that would be repeated and could be used to more simply describe repetitive and long-duration complex activities.

The posture of five physiotherapists performing five 20-min MLD at their workplace was captured by two cameras. From the recordings, the adopted postures were extracted every 5 s and quantified through 13 joint angles, that is, 6594 analyzed postures. Rapid Upper Limb (RULA) and Rapid Entire Body Assessment (REBA) were used to assess MSDs risks. A hierarchical analysis was used to define GP.

Seven GP were identified through mean values and standard deviation. GP ergonomic assessment showed a low to moderate MSD risk (RULA between 3 and 6 and REBA between 2 and 7). High neck (&gt;20°) and trunk (&gt;15°) flexion were observed for all GP. High shoulder abduction and flexion (&gt;40°) were evidenced for GP3 to GP5. GP1 was the most used (34%) and presented the lowest ergonomic scores (RULA: 4.46 ± 0.84; REBA: 5.06 ± 1.75). GP3 to GP6 had frequency of between 10 and 20%. GP5, GP6, and GP7 obtained the highest ergonomic scores (RULA&gt;5; REBA&gt;7). All physiotherapists use different GP combinations to perform MLD.

MLD could be described as a combination of GP. Ergonomic analysis showed that MLD exposes physiotherapists to low at moderate MSD risks.
