Semen preservation technique includes chilling at 4-5 oC and cryopreservation at -196 oC. The role of extender enriched with protectant is essential for storing sperm. In order to evaluate the effects of different concentrations of soybean lecithin (SL) in Tris-based extender on quality parameters of chilled canine semen and subsequent potential. The Trisbased extenders with 0.5%, 1.0% or 2.0% SL (w/v) were used to store the sperm of French Bulldog; meanwhile, Tris-based extenders supplemented with 20.0% (v/v) egg yolk (EY) were used as the control group. Sperm samples in each group were stored at 4⁰C for 168 hours period.

Particulate matter (PM) concentrations are significantly higher in urban railway tunnels (178.1 μg/m3) than in metropolitan areas (49 μg/m3). Nitrogen oxide (NOx) concentrations, which are a direct cause of lung disease, have been found to exceed the atmospheric standard of the Ministry of Environment in tunnels in Korea. Dust generated by trains is scattered at high speed along tunnels, making filtration difficult. The development of filters that can be used in tunnels is urgently required. In this study, the results of using an activated carbon filter (ACF) were analyzed and compared with the laboratory-scale PM adsorption using functional activated carbon non-woven fabric filters (Cerebasel, Cerecore) that can be manufactured in Korea. The fine PM concentration, filter depth, and flow rate in the tunnel were the experimental variables. We compared PM concentrations before and after the filter experiments, and calculated the PM removal efficiency to determine the optimal conditions.
Prevention of obstetric trauma from damage to the pelvic floor is not always possible and sacral nerve stimulation (SNS) may be necessary later in life. Sacral nerve stimulation has been a promising innovation in the management of moderate to severe faecal incontinence and following sphincter repair failure. Although the indication spectrum for SNS is expanding, the success of neuromodulation for constipation is limited. Adverse events of SNS requiring reintervention are not common but a long-term successful outcome may depend on interventions for maintenance of the device.
Diverse Feed, Diverse Benefits - The Multiple Roles of Feed Diversity at Pasture on Ruminant Livestock Production - a Review
Several scientists called for a new paradigm in animal nutrition by implementing feed diversity in otherwise homogeneously fed livestock production systems as former was shown to have a notable impact on animal productivity and health and the ecological footprint thereby decrease concerns regarding global food security from a societal perspective. However, there are no specific definitions and no threshold values available, so far, for desired grazed grassland feed diversity levels on pastures that enable envisaged sustainable ruminant livestock production and possibly the production of animal products with particular human health-values. Therefore, we conceptualize grazed grassland feed diversity in multiple layers for the very first time in this review to define its relevance from an animal perspective and implications for human health. The data reviewed reveals a close relationship between grazed grassland feed diversity with regard to plant secondary metabolites and animal characteristics that include animal health, welfare, and behavior as well as product quality with possible human health value.
