Annotation of the output with contextual information concerning the description of creative process and the content of the research/artistic/other activity, etc. | A scientific study analyses the impact of alternative bedding materials (e.g. a combination of ground limestone, straw, water and separated manure) on the hygiene and health of the mammary gland in dairy cows. The results confirm that these materials, thanks to the adjustment of pH and humidity, effectively reduce the occurrence of indicator microorganisms (coliform bacteria, streptococci) in the litter boxes. Lower bacterial pressure directly reduces the level of teat contamination, minimizes the risk of mastitis and improves overall mammary gland health, which leads to a lower number of somatic cells in the milk. |

| OCA16. Annotation of the output in English | The aim of this study was to compare an improved bedding composition with conventional straw bedding under farm conditions, regarding its effects on the influence of indicator microorganisms on the hygiene levels of cubicle floors and the occurrence of mastitis in dairy cows. Dairy cows were housed in newly built stalls divided into two parts, each with four subsections, and bedded cubicles arranged in three rows. Five stall subsections from each 9-bedded cubicle were selected for study, and 30 dairy cows were monitored according to the time intervals of bedding treatment for cubicles. In the first subsection (control), the cows were housed in bedded cubicles layered with straw up to a height of 20 cm. Sections 2–5 had alternative bedding (AB) as follows: fresh AB, AB 1 month old, AB 2 months old, and AB 3 months old, which were bedded one day before (fresh) and 1–3 months before the actual observation period, respectively. The alternative bedding per one cubicle consisted of ground limestone (100 kg), water (80 L), recycled manure solids (RMS; 15 kg), and straw (25 kg). After laying, the bedding was treated with a concrete selector to provide strength and sufficient resistance. A total of 180 bedding and 600 quarter milk samples were taken simultaneously from all five monitored subsections for microbiological determination. Comparing classical straw bedding with the alternate bedding showed a stabilizing effect by keeping the bedding thickness up to the floor barrier level, which had a beneficial effect by reducing the level of fecal contamination in the rear of the cubicle. Fecal coliforms and fecal streptococci were found to be reduced in one-day-old bedding as well as after the first, second, and third months. By evaluating the health status of the mammary glands, a positive effect was noted in reducing the occurrence of subclinical mastitis, which was reflected in a reduced number of infected quarters in the group of cows housed in cubicles for three months after use of improved bedding. |

| OCA18. Characteristics of the output's impact on socio-economic practice | The use of alternative bedding mixtures, such as combinations of ground limestone, straw, water and separated manure, brings significant benefits for socio-economic practice in the dairy farming sector. From an economic point of view, this innovation directly increases the profitability of farms, as healthy dairy cows produce higher quality milk and ensure stable herd performance. At the same time, farmers achieve massive savings on costs associated with mastitis treatment, antibiotic purchases and premature culling of sick animals. In addition, replacing traditional straw or sawdust with recycled separated manure reduces the dependence of companies on the fluctuating prices of purchased input materials. |

| OCA19. Characteristics of the output and related activities' impact on the educational process | Knowledge about the impact of litter on microbiology and mammary gland health brings practical experience to students who learn to work with real data from the operation. Topics such as circular economy (use of separate), animal welfare and reducing antibiotic consumption become an integral part of subjects such as Animal Husbandry, Breeding Hygiene and Agricultural Economics. Education thus directly responds to current trends in European agricultural policy. |
