A pilot study about on-farm assessment of health and welfare in rabbits kept in different housing systems.

This pilot study tested an on-farm protocol based on resource, management, and animal-based measures to evaluate the on-farm health and welfare of rabbits kept in four different housing systems. In detail, the four housing systems were (1) standard breeding cages for reproducing does (3,300 cm) with their litters associated with bicellular cages for growing rabbits (1,200 cm); (2) dual-purpose cages for both reproducing does and growing rabbits (3,655 cm); (3) enriched cages (4,739 cm) for both reproducing does and growing rabbits equipped with a wire-mesh elevated platform (1,015 cm); (4) parks (30,977 cm) made up of four modules (7,744 cm each) joined by removing the wire net walls between them with growing rabbits kept in collective parks and reproducing does individually in the single modules. A total of 12 commercial farms (three farms/four housing systems) were visited during three seasons (summer, autumn, and winter) on two occasions each: (1) a pre-weaning visit for recordings on reproducing does and litters and (2) a pre-slaughtering visit for recordings on growing rabbits.

Antibiotic Use in Alpine Dairy Farms and Its Relation to Biosecurity and Animal Welfare.

The quantification of antimicrobial usage (AMU) in food-producing animals can help identify AMU risk factors, thereby enhancing appropriate stewardship policies and strategies for a more rational use. AMU in a sample of 34 farms in the Province of Trento (north-eastern Italy) from 2018 to 2020 was expressed as defined daily doses for animals per population correction unit according to European Surveillance of Veterinary Antimicrobial Consumption guidelines (DDDvet) and according to Italian guidelines (DDDAit). A retrospective analysis was carried out to test the effects of several husbandry practices on AMU.

Short-term and long-term effects of antimicrobial use on antimicrobial resistance in broiler and turkey farms.

RESEARCH HIGHLIGHTSSulfamethoxazole and ampicillin resistance are the highest in isolates of both broilers and turkeys.Short-term effects of antibiotic use on resistance are seen more often than long-term effects.Historical penicillin use is associated with penicillin resistance in broilers.

Antimicrobial Use in Broilers Reared at Different Stocking Densities: A Retrospective Study.

According to the Directive 2007/43/EC, broiler farms can house animals up to 39 kg/m, provided that specific environmental requirements are met. However, limited information is available about the effects of stocking density (SD) on broiler health and welfare, including the need for antimicrobial use. In this study, annual data on mortality, feed conversion rate, and antimicrobial use (AMU) are compared between broiler farms with stocking densities of 39 kg/m (N = 257) and 33 kg/m (N = 87).

Unrevealed genetic diversity of GII Norovirus in the swine population of North East Italy.

Noroviruses (NoVs) are one of the major causative agents of non-bacterial gastroenteritis in humans worldwide. NoVs, belonging to Caliciviridae, are classified into ten genogroups (G) and eight P-groups based on major capsid protein (VP1) and of the RNA-dependent-RNA-polymerase (RdRp), respectively. In swine, the main genogroup and P-group identified are GII and GII.

Identification of two divergent swine Noroviruses detected at the slaughterhouse in North East Italy.

Norovirus (NoV) has emerged as one of the major causative agents of non-bacterial, food- and water-borne gastroenteritis in humans, with the main genogroup involved in human outbreaks (GII), which has been detected worldwide in different animal species including swine. A four-month investigation at the slaughterhouse aiming to examine the presence of NoV in the swine in North-Eastern Italy, enabled the detection of two divergent Noroviruses (NoVs) (GII.P11) in two swine farms.

Antimicrobial use on Italian Pig Farms and its Relationship with Husbandry Practices.

The analysis of antimicrobial use (AMU) data in livestock allows for the identification of risk factors for AMU, thereby favoring the application of responsible AMU policies on-farm. Herewith, AMU in 36 finishing pig farms in northern Italy from 2015-2017 was expressed as defined daily doses for Italian pigs (DDDita) per population correction unit (DDDita/100kg). A retrospective analysis was then conducted to determine the effects of several husbandry practices on AMU.

Identification of a zoonotic genotype 3 hepatitis E subtype in wildlife in north-eastern Italy.

Hepatitis E virus (HEV) is an emerging zoonosis caused by a positive RNA single stranded virus of the Hepeviridae family. In developed countries, pigs and wild boars are the main reservoir for zoonotic genotypes 3 and 4. In spring 2017, for the first time HEV was detected in wild boars captured in the Regional Park of the Euganean Hills, in north-eastern Italy.

Integration of genetic and epidemiological data to infer H5N8 HPAI virus transmission dynamics during the 2016-2017 epidemic in Italy.

Between October 2016 and December 2017, several European Countries had been involved in a massive Highly Pathogenic Avian Influenza (HPAI) epidemic sustained by H5N8 subtype virus. Starting on December 2016, also Italy was affected by H5N8 HPAI virus, with cases occurring in two epidemic waves: the first between December 2016 and May 2017, and the second in July-December 2017. Eighty-three outbreaks were recorded in poultry, 67 of which (80.
