THE ROLE OF PROBIOTICS IN IMPROVING GUT HEALTH AND IMMUNE FUNCTION IN DAIRY COWS

Abstract

The objective of this study was to investigate the effects of probiotic supplementation on gut health, immune function, and milk production in dairy cows. A total of 60 dairy cows were randomly assigned to a treatment group receiving daily probiotics (Lactobacillus and Bifidobacterium) and a control group that did not receive probiotics. Baseline data on microbial composition, immune parameters, and milk yield were collected before the supplementation period. After 60 days of probiotic supplementation, significant changes were observed in the treatment group compared to the control. Microbial analysis revealed a marked increase in beneficial bacteria, such as Lactobacillus and Bifidobacterium, and a significant reduction in harmful bacteria, including Escherichia coli. Immune function was notably enhanced in the treatment group, with increased white blood cell counts and improved cytokine profiles. Probiotic treatment enhanced milk production of nursing mothers while simultaneously improving the milk quality by raising fat and protein concentrations.  Participants in the therapy group recorded lower frequencies of gastrointestinal problems together with reduced mastitis occurrence.  Probiotic supplements enable dairy cows to generate additional milk quantity alongside immune system strengthening effects and enhanced gastrointestinal well-being based on test result data.  The research results confirm extensive scientific evidence about using probiotics over prolonged time periods to boost cattle health and agricultural production capabilities.  Greater research into dairy cow health treatments must be conducted to determine the best probiotic strains and dosage methods.
