The present thesis provides a review of the different therapies for the treatment of Repeat Breeder Syndrome (RBS) in dairy cows and an article on the bactericidal effect of Ozone for the treatment of subclinical endometritis (SCE), one of the determinant factors of the above-mentioned syndrome. Chapter 1 includes a review of the literature on the etiopathogenetic causes and currently used therapies, both classic and innovative, for the treatment of Repeat Breeder Syndrome. Based on an in vitro study in which the microbicidal effect of an Oxygen/Ozone gas mixture was evaluated, the research discussed in Chapter 2 was developed. In this chapter, the in vivo bactericidal activity of ozone, by administering an O3/O2 gas mixture via intrauterine route, in Repeat Breeder cows affected with subclinical endometritis (SCE) at the time of heat, was evaluated. Finally, the ‘General Discussion and Conclusions’ section analyses the possible use of the ozone therapy as an alternative to antibiotics treatments of subclinical uterine pathologies, which determine the Repeat Breeder syndrome. This new information is particularly relevant in the buiatric field in the treatment of this pathology, which has a negative impact on the farm's economic balance. Moreover, the use of ozone would make it possible to reduce the use of antimicrobials in livestock, bringing both economic benefits and a reduction in the worldwide phenomenon of antibiotic resistance.
La presente tesi fornisce una rassegna sulle diverse terapie per il trattamento della Sindrome Repeat Breeder (RBS) nelle vacche da latte e un articolo sull’effetto battericida dell’Ozono per il trattamento dell’endometrite subclinica (SCE), determinante la sopracitata sindrome. Il Capitolo 1 comprende la revisione della letteratura sulle cause eziopatogenetiche e sulle terapie attualmente utilizzate, classiche ed innovative, per il trattamento della Sindrome Repeat Breeder. Sulla base di uno studio in vitro in cui è stato valutato l’effetto microbicida di una miscela di gas Ossigeno/Ozono, è stata sviluppata la ricerca trattata nel capitolo 2. In tale capitolo è stata valutata l’attività battericida dell’Ozono, somministrato per via intrauterina, sottoforma di miscela gassosa O3/O2, in bovine Repeat Breeder con endometrite subclinica (SCE) al momento del calore. Infine, la sezione “Discussione generale e conclusioni” evidenzia come l'ozono-terapia sia una valida ed efficace alternativa agli antibiotici nel trattamento di patologie uterine subcliniche, determinanti la sindrome Repeat Breeder. Queste nuove informazioni sono particolarmente rilevanti in ambito buiatrico nel trattamento di questa patologia che impatta in maniera negativa sul bilancio economico aziendale. Inoltre, l’utilizzo dell’Ozono permetterebbe di ridurre l’uso degli antimicrobici negli animali da reddito, apportando benefici sia economici che sulla riduzione del fenomeno mondiale dell’antibiotico resistenza.

Abstract
The present thesis provides a review of the different therapies for the treatment of Repeat Breeder Syndrome (RBS) in dairy cows and an article on the bactericidal effect of Ozone for the treatment of subclinical endometritis (SCE), one of the determinant factors of the above-mentioned syndrome. Chapter 1 includes a review of the literature on the etiopathogenetic causes and currently used therapies, both classic and innovative, for the treatment of Repeat Breeder Syndrome. Based on an in vitro study in which the microbicidal effect of an Oxygen/Ozone gas mixture was evaluated, the research discussed in Chapter 2 was developed. In this chapter, the in vivo bactericidal activity of ozone, by administering an O3/O2 gas mixture via intrauterine route, in Repeat Breeder cows affected with subclinical endometritis (SCE) at the time of heat, was evaluated. Finally, the ‘General Discussion and Conclusions’ section analyses the possible use of the ozone therapy as an alternative to antibiotics treatments of subclinical uterine pathologies, which determine the Repeat Breeder syndrome. This new information is particularly relevant in the buiatric field in the treatment of this pathology, which has a negative impact on the farm's economic balance. Moreover, the use of ozone would make it possible to reduce the use of antimicrobials in livestock, bringing both economic benefits and a reduction in the worldwide phenomenon of antibiotic resistance.File | Dimensione | Formato | |
