“…Regarding other livestock species, a serological study in dairy cows carried out in two neighboring Northern Italian regions (Lombardy and Veneto) that account for over 50% of the Italian dairy cattle population reported a herd-level apparent prevalence of 48 and 65%, respectively ( 39 ). Similar results was obtained in a large-scale survey in water buffaloes ( Bubalus bubalis ) in Campania reporting an apparent prevalence of infection of 54.7% ( 40 ). Our results support previous studies and confirm the high prevalence of MAP infection in Italian livestock.…”

IntroductionParatuberculosis (PTB) is a worldwide chronic, contagious enteric disease caused by Mycobacterium avium subsp. paratuberculosis (MAP) mainly affecting ruminant species. PTB is a WOAH-listed disease with direct and indirect economic losses in the livestock sector, negative impact on animal welfare and significant public health concerns. In spite of this, MAP prevalence in small ruminants is still unknown and the prevalence appears to be underestimated in many countries. The aim of this study is providing a first large-scale serological survey on MAP infection in small ruminants in Sicily, a region of Southern Italy with the 11.3 and 8.9% Italian national heritage of sheep and goats, respectively.MethodsFor this purpose, we analyzed a total of 48,643 animals reared in 439 flocks throughout Sicily. MAP seroprevalence was estimated both at herd-level and animal-level within breeds reared in all the nine sampled provinces.ResultsOur results revealed a high overall apparent prevalence at herd-level of 71.8% in sheep and 60.8% in goat farms with an animal-level prevalence of 4.5 and 5.1% in sheep and goats, respectively. Significant statistical differences were found between the provinces and within the breeds both in sheep and goats.DiscussionOur study provides the first large-scale serological survey on PTB infection in small ruminants in Sicily and showed a high prevalence of disease depending to the species, breed and province. This study represents the first step to better understand the MAP epidemiology in a typical Mediterranean breeding context, suggesting the need of in-depth study on the herds risk factors, including the eventual presence of candidate genes for resistance/susceptibility to PTB in native breeds.

“…Therefore, it is not possible to exclude a consistent risk of exposure in cases of faecal contamination of goat milk given the high variability of MAP excretion levels with faeces in ruminants. For these reasons, the only way to reduce the risk of goat milk contaminated by MAP seems to be the adoption of control plans aimed at reducing the intra-herd prevalence of paratuberculosis, as recently suggested for the managing and breeding of other species [39].…”

Goat Paratuberculosis: Experimental Model for the Evaluation of Mycobacterium Persistence in Raw Milk Cheese

Mycobacterium avium subsp. paratuberculosis (MAP) is the causative agent of chronic proliferative enteritis found in ruminants, known as paratuberculosis (PTB). The spread of PTB is increasing in countries with advanced animal husbandry practices, leading to significant economic losses. Moreover, a supposed zoonotic role of MAP in Crohn’s disease (CD) in humans has been discussed by the scientific community; however, although the association between MAP and CD has generally been accepted, it is still up for debate if MAP is the main cause of CD, a contributing factor, or merely a commensal organism for the development of CD. The aim of this study was to assess the survival of MAP during the entire production process of a traditional Italian goat’s raw milk fresh cheese, the “Robiola di Roccaverano”, assessing the survival rate and persistence of MAP in the final product. A mix of MAP field isolates from goats of the Roccaverano area and a reference ATCC strain were used to carry out milk in experimental inoculation. Samples of milk, curd and cheese were taken in two consecutive batches of production. Microbiological challenge tests, evaluated by f57-qPCR, showed a significant decrease in MAP charge during the cheesemaking process for both batches, suggesting the productive process has an impact on MAP survival.

“…The growing demand for buffalo mozzarella in the last few decades has driven a rapid intensification of the sector in terms of increased use of off-farm inputs and implementation of genetic improvement techniques [5,6]. The shift from extensive to intensive modes of production has increased the stocking rate and then the environmental impact of buffalo farming in terms of worsening air and water quality, as well as animal welfare and health, even facilitating occasional animal disease outbreaks [7][8][9][10]. Moving buffalo farming from the traditional coastal plains to inland hilly zones could mitigate the issues related to buffalo farming along with revitalizing the economy and contrasting the depopulation of more marginal zones [11][12][13].…”

Moving Buffalo Farming beyond Traditional Areas: Performances of Animals, and Quality of Mozzarella and Forages

An observational case study was designed to highlight issues associated with a possible expansion of dairy buffalo (Bubalus bubalis) farming outside the traditional coastal plains of southern Italy. Twenty pregnant buffaloes were transferred to a hilly inland farm. After calving, production and reproduction data were collected monthly throughout lactation. From 4 to 6 months of lactation, buffaloes were enrolled in a feeding trial to evaluate the effects of locally grown forages (maize silage vs. hay) on milk production and in vivo digestibility. Sensory properties of mozzarella cheese produced at a local dairy were also evaluated. No obvious effects of diet were found. Compared to the data recorded in the previous lactation completed in the farm of origin, milk yield was reduced by 37.2%, and milk protein by 6.1%, whereas milk fat improved (+4.5%). A lower pregnancy rate (−13.3%), increased days open (+122%), and a prolonged intercalving period (+26.9%) were also observed. Lactation length was shorter than the standard value of 270 d. The results showed that peculiar reproductive characteristics, lower environmental temperatures, and the specificity of the mozzarella production process are the main problems to be addressed in an expansion of buffalo farming outside traditional areas.
