Machine learning prediction of sleep stages in dairy cows from heart rate and muscle activity measures.

Sleep is important for cow health and shows promise as a tool for assessing welfare, but methods to accurately distinguish between important sleep stages are difficult and impractical to use with cattle in typical farm environments. The objective of this study was to determine if data from more easily applied non-invasive devices assessing neck muscle activity and heart rate (HR) alone could be used to differentiate between sleep stages. We developed, trained, and compared two machine learning models using neural networks and random forest algorithms to predict sleep stages from 15 variables (features) of the muscle activity and HR data collected from 12 cows in two environments.

Fungal Genomic Resources for Strain Identification and Diversity Analysis of 1900 Fungal Species.

Identification and diversity analysis of fungi is greatly challenging. Though internal transcribed spacer (ITS), region-based DNA fingerprinting works as a "gold standard" for most of the fungal species group, it cannot differentiate between all the groups and cryptic species. Therefore, it is of paramount importance to find an alternative approach for strain differentiation.

Meat eating and nutritional quality of lambs sired by high and low muscle density rams.

Intramuscular fat (IMF) content affects eating and nutritional quality of lamb meat. Muscle density measured by computer tomography is an in vivo proxy measure of IMF content that affects eating and nutritional quality of lamb meat. Lambs sired by high muscle density (HMD) or low muscle density (LMD) rams, selected for slaughter on commercial criteria were measured for meat quality and nutritional traits.

Further evaluation and validation of HybridoMed Diff 1000 and its comparison to Basch medium for the cell-free culture of Schistosoma mansoni juvenile worm stages.

Schistosomules of the human parasite Schistosoma mansoni are vital for research focusing on the fundamental functional/developmental biology of schistosomes and many anti-schistosomal drug discovery programmes. Through the further evaluation and validation of a recently tested media, HybridoMed Diff 1000 (HM), for the cell-free culture of juvenile schistosomules, we show that while Basch medium was superior to HM for the survival/development of schistosomules, HM represents a viable and attractive alternative for somule culture, particularly to the early liver stage. Adoption of HM for schistosomule culture could facilitate more standardised approaches, which for drug screening should enable improved multi-centre target-hit evaluation.
