The reproductive performance of dairy animals is influenced by several factors, and accumulating lines of evidence indicate that mastitis is one of the determinants. Most of the published information relating mastitis with reproduction has evolved based on retrospective approach rather than controlled clinical studies. The complex nature of both mastitis and reproduction could be a limiting factor for understanding their relationship in detail. In this review, we analyzed the available retrospective studies on the effects of clinical mastitis on reproductive function and explained the possible mechanisms by which mastitis affects reproduction in dairy animals.

The objectives of this study were: (i) to evaluate the associations between postpartum health disorders, relative increase in walking activity (RIWA) and expression of behavioral estrus intensity captured by pedometers; (ii) to assess associations between RIWA and pregnancy in cows submitted to timed artificial insemination (TAI). Lactating dairy cows (n = 881) were enrolled in the study. Cows were submitted to a 5d TAI protocol with insertion of a progesterone device.

Th/Th polarisation and suppressor of cytokine signalling-3 (SOCS3) are important indicators of the humoral and cellular immune system activity in cows. The aim of this study was to determine the correlation of postpartum diseases with the levels of Th/Th polarisation and SOCS3 at the time of parturition. The study examined 180 cows (90 with normal parturition [NP] and 90 with dystocia [D]).

Establishing a high-throughput detection technology for amino acid (AA) content in milk using mid-infrared (MIR) spectroscopy has profound implications for enhancing nutritional value of milk, identifying superior milk sources, producing specialty dairy products, and expanding Dairy Herd Improvement (DHI) metrics. The aim of this study was to evaluate the effectiveness of MIR spectroscopy in predicting the content of 15 individual total AA (TAAs) and 16 free AA (FAAs) in bovine milk as well as to investigate the major factors affecting the phenotypic variability of AA content. From March 2023 to March 2024, 513 milk samples were collected from 10 Holstein dairy farms in China and analyzed using Bentley spectrometers for MIR measurements.

Lipoteichoic acid (LTA), an organic acid of Gram-positive bacteria, is closely related to mastitis in dairy cows. This study evaluates the effect of LTA-induced endoplasmic reticulum stress (ER stress) in vitro using MAC-T (mammary epithelial cells) and in dairy cows with mastitis. LTA stimulation significantly increases ER stress and apoptosis-related factors in MAC-T.

Pediococcus pentosaceus is well known for its probiotic properties, including roles in improving health, antimicrobial production, and enhancing fermented food quality. This study aimed to comprehensively analyze the whole genome of P. pentosaceus MBBL6, isolated from healthy cow milk, to assess its probiotic and antimicrobial potentials.
