Decision Support Systems (DSS) streamline dairy farm management by addressing challenges in productivity, animal welfare, sustainability, and economics. Yet, their precise impact on dairy cattle farm operations remains unclear. This scoping review systematically analyses DSS applications in dairy farming using studies from Scopus and Web of Science published between 2005 and June 2025, following PRISMA-ScR guidelines. From 1 112 identified records, 84 studies were included, after deduplication and screening, and classified into four mutually exclusive primary categories, namely data-, model- and knowledge-driven and other specialised DSS. The...

In this study, different strains were used to ferment single/mixed cottonseed meal (cottonseed meal, corn flour, bran ratio of 7 : 2 : 1) substrates, and their feeding value was evaluated by an in vitro fermentation trial, to select suitable fermentation strains for cottonseed meal. For this purpose, two experiments (Exp.) were conducted. Exp. 1: Evaluation of the effect of fermentation of single cottonseed meal by different strains, which consisted of ten treatment groups: control (CON), Saccharomyces No. 1 (T1), Saccharomyces Fubon (T2), Saccharomyces Lallemand (T3), Lactobacillus (T4), Bacillus...

The aim of the study was to compare the muscle protein quality in the m. longissimus, pars thoracis of bulls of the Aberdeen Angus (AA) and Czech Fleckvieh (CF) breeds reared under identical conditions within an extensive pasture-based system. The CF breed exhibited a higher crude protein content (887 ± 87.4 g/kg of dry matter) compared to AA (812 ± 59.3 g/kg of dry matter); P ≤ 0.05. A higher content of non-essential amino acids was recorded in CF (390 ± 37.9 g/kg of dry matter) compared to AA (364 ± 44.5 g/kg of dry matter); P ≤ 0.05, as well as higher contents of essential amino...

This study examines methods for detecting illegal manipulation of raw cow’s milk aimed at artificially reducing the somatic cell count (SCC) through centrifugation. This practice, motivated by economic gain, compromises the authenticity of the raw material and masks the true health status of the mammary gland. An experimental analysis of 68 samples demonstrated that centrifugation reduces somatic cell count by an average of 45.9 ± 11.6%. The MALDI-TOF MS method was used to identify changes in the peptide profile in the 500–4 000 Da range. Although no unique peaks specific to adulterated samples were detected, Pearson’s...
