“…Mastitis is a common disease of dairy cows, accompanied by physical, chemical, pathological, and bacteriological changes in milk and glandular tissue (Tezera and Ali 2021;El-Demerdash et al 2023). Mastitis reduces the milk output of cows by 20-30%, significantly affecting livestock productivity, especially subclinical and clinical forms of mastitis (Bekuma and Galmessa 2019;Nguyen et al 2020;Mohsin et al 2022;Nguyen et al 2023). If the mastitis disease in cows continues to exist without prompt and timely treatment, the udder leaves will undergo atrophy, resulting in the inability to produce milk.…”

A total of 20,823 Holstein × Lai Sind crossbred dairy cows from three farms in Central and East-Southern Vietnam were examined to clarify the prevalence of clinical mastitis and evaluate its effects from July to October 2022. The results indicated that clinical mastitis in cows was present at a relatively low rate (7.05%), and the high-density farms had a higher rate of clinical mastitis in cows than in other farms. In a hot, humid month, the incidence of clinical mastitis in cows (7.78%) was higher than in other months in this study, especially in the high-density farm. Cows at the first parity were clinical mastitis (32.58%) higher than at other parities, followed by cows at the second parity. As indicated, farm scale, months, and parity affected the incidence of clinical mastitis in cows in those survey farms. Clinical mastitis caused the fluctuation in milk yield, which was determined at 15.45±8.67 to 18.44±0.72 kg/cow/day; moreover, the milk yield of clinical mastitis cows in the large-scale farm showed a significant fluctuation. Among examined bacterial pathogens, Streptococcus agalactia (34.65%) was the most detected from milk samples of clinical mastitis cows, followed by Klebsiella (14.47%) and Escherichia coli (10.09%), but Staphylococcus spp. was present at the lowest rate (0.88%). The treatment followed the veterinarian's guidelines and was adequate for clinical mastitis cows in this study within five days (79.15%). Thus, mastitis management in dairy farms is significantly required to prevent disease spreading in farms, especially in high-density herds.

“…During infections of mammary glands, neutrophils are the first immune cells that migrate from the circulation to the inflammatory area. Furthermore, neutrophils require energy for their activity, and cows with a negative energy balance (NEB) have a predisposition for the occurrence of mastitis [10].…”

Mastitis is one of the most important diseases in dairy cows, leading to substantial economic losses associated with decreased milk production and quality. Early detection of changes in metabolic and milk parameters is crucial for maintaining animal welfare and milk quality. This study aimed to detect patterns in metabolic and milk composition parameters in Serbian dairy cows affected by mastitis. It also examined the relationship between these factors in cows with clinical and subclinical mastitis, as well as in healthy cows. This study included 60 Holstein-Friesian cows with the same body score condition that were in the same lactation phase. They were divided into three groups of 20: clinical and subclinical mastitis and a control group of healthy cows. The categorization was based on clinical udder health and the California mastitis test. Blood serum metabolic profiles were measured using a Rayto spectrophotometer (Shenzhen, China), and milk composition was determined using MilcoScanTM (Foss, Hilleroed, Denmark) and FossomaticTM (Foss, Hilleroed, Denmark) instruments. Significant increases in non-esterified fatty acids (NEFAs), beta-hydroxybutyrate (BHB), total protein, globulin, urea, total bilirubin, magnesium, and enzyme activity were noted in mastitis-affected cows compared to healthy ones. Additionally, mastitis-affected cows had higher total protein and globulin levels and increased somatic cell counts (SCCs), while albumin concentrations were decreased. Furthermore, a negative correlation between total protein and lactose suggested inflammation leading to reduced lactose levels due to cell damage, infection, and lactose use by mastitis pathogens. Hence, indicators of the energy and protein status of the metabolic profile, together with the chemical composition of milk, may be significant diagnostic tools for detecting, monitoring, and predicting the outcome of mastitis in cows.
