J.M. Huzzey's research while affiliated with California Polytechnic State University, San Luis Obispo and other places

... A previous research showed that high UREA reflects the high decomposition rates of proteins and amino acids and indicates the levels of fatigue in the body . High levels of NEFA in the blood are often used as a sign of negative energy balance or fat mobilization (Hendriks et al., 2022). Compared with WCS without FPPR, the partially replaced feeds contained more energy that can be provided to goats and were more beneficial to goat fat deposition during production. ...

... Lying laterality in dairy cows has been addressed by Gibbons et al. (2012) and Forsberg et al. (2008). The relationship between movement activity and the lying frequency of grazing cows was also discussed by Hendriks et al. (2020). ...

... Most primary research on cattle sickness behavior has been studied in dairy cows with common dairy production diseases, such as hypocalcemia, ketosis, metritis, mastitis, and lameness. Sick dairy cows displayed increased resting/ lying duration (57)(58)(59), decreased activity (60, 61), and decreased feeding behaviors [e.g., time at feeder, number of feeder visits, feed intake (59,(62)(63)(64)(65)]. Sick dairy cows also expressed decreased duration ruminating (60,61). ...

... A total of 30 cows were used during the studies. These cows were not inseminated and with no signs of genital disease or microbial infection based on cytologic examination and the presence of foul smell, characteristic visual appearance and vaginal discharge [78]. Clinical diseases other than metritis or endometritis, such as milk fever, mastitis, clinical ketosis, and displacement of the abomasum were diagnosed according to farm protocol by experienced farm staff or the herd veterinarian. ...

... Serum ceruloplasmin molecules contain more than 95% of serum Cu, so the increase of serum Cu values was attributed to ceruloplasmin increase (Spears and Weiss 2008). Ceruloplasmin is a positive acute phase protein (APP) that enhances in parallel to other APPs such as Hp during metabolic and oxidative stress after parturition (Huzzey et al. 2015;Batistel et al. 2016). In the present study, the highest Cu concentrations were seen concurrently with the reduction of BCS and sharp increase of Hp, FRAP, MDA and reduction of PON1 activities. ...

... Hepatocytes were collected at different time points after adding different concentrations of BHBA to evaluate oxidative stress and the activity and expression of some antioxidant biomarkers in hepatocytes. Negative energy balance is known to occur in dairy cows following parturition because in a situation of low dry matter intake and increased energy requirements to support milk production (25), lipids are mobilised to release nonesterified fatty acids (NEFA) into the bloodstream and serve as an energy source. Excess lipid mobilisation causes ketosis in cows (47), and increased blood NEFA concentrations affect postpartum cow health. ...

... Investigation of fine-scale animal behaviour can improve the understanding of animals' functional response to the environment [2] and provide an important indicator of animal welfare [3]. Initial responses to stressors related to changes in animal management or environment are often behavioural and can provide the first indications of stress or impaired health of an individual [4,5]. Triaxial acceleration sensors have been frequently used to study fine-scale animal behaviours in both wild [6,7] and domesticated species [8,9]. ...

... Another study did not detect differences in the number of successful replacements per day [extrapolated from RIC data of Huzzey et al. (35)] as stocking density increased from 1:1 to 3:2 and 3:1 cows per bin (36); however, they did not evaluate displacement or replacement attempts, which require video analysis. More studies are needed to evaluate whether our nonlinear response pattern in direct competition across stocking densities would be replicated in other settings. ...

... In nature, goats rely on social information to determine patch quality, but when foraging alone, they must rely on direct sampling of food patches to identify differences in quality (40). Previous experimental work in goats has also shown goats will change between food sources when faced with low quality feed; when goats were presented with low-or high-quality feed in the arms of a T maze, they would often switch to the other arm if they initially chose the low-quality arm (41). Similarly, in cattle, Huzzey et al. (42) reported that heifers fed a diet with lower energy density compared to that of a previous period increased their changes between feeding stations. ...
