Background: Dairy productivity can be improved by controlling metabolic diseases in dairy cows such as milk fever. The aim of this study was to estimate the cumulative incidence of milk fever during four years (2019 to 2022) at an anonymous dairy farm in the Emirate of Abu Dhabi. For this study, the records of the diagnosis of milk fever in 7540 parturient cows during four years was used.

The purpose of the paper was to apply an Artificial Neural Networks with Radial Basis Function to develop an application model for diagnosing a subclinical ketosis type I and II in dairy cattle. While building the neural network model, applied methodology was compatible to the procedures used in Data Mining processes. The data set was created based on the composition of milk samples of 1520 Polish Holstein-Friesian cows.

Article Synopsis
- The incidence of metabolic diseases in dairy cows peaks around parturition due to hormonal and physiological changes, making reliable monitoring essential.
- Blood tests are costly and stressful for cows, leading to the exploration of mid-infrared spectroscopy (MIR) as a non-invasive alternative to assess nutritional and metabolic health.
- The study conducted on 349 Holstein cows revealed that while MIR can predict certain blood traits like BHB and NEFA, its accuracy isn't perfect, yet it can still help identify cows at risk for negative energy balance and assist in herd management and decision-making.
M1 polarization of hepatic macrophages in cows with subclinical ketosis is an important cause of liver injury.

Subclinical ketosis (SCK) is highly prevalent and easily overlooked, with insidious and slow progression of hepatic injury, often characterized by an imbalance in immune homeostasis. In nonruminants, macrophage polarization plays an important regulatory role in hepatic lipid accumulation, fibrosis and inflammatory processes. Thus, we aimed to investigate the status of hepatic macrophage polarization in SCK cows and to corroborate its association with liver injury and inflammation.

Article Synopsis
- * Out of 145 cows tested, 42 were found to be BLV-seropositive, with many experiencing health issues, but there was no significant difference in milk production between infected and non-infected cows.
- * Metabolomic analysis showed notable differences in cow metabolism linked to BLV, identifying specific disrupted metabolites related to energy metabolism, immune function, and potential early cancer indicators, which could help in detecting infected cows and understanding the disease better.
