The goal of the trial was testing effects a blend organic acids and essential oils dietary supplementation on growth performance gut healthiness in broiler chickens. In total, 420 male Ross 308 chicks (1-day old) were randomly assigned to two treatments: basal (BD) (OA&EO) diets (three replicates/treatment; 70 broilers/replicate). BD group received commercial whereas OA&EO + 5 g/kg microencapsulated oils. treatment improved average daily gain (p < 0.01) feed conversion ratio at...
Background:Staphylococcus aureus is one of the most prevalent pathogens causing mastitis in dairy animals and represents a serious issue public health concern due to its resistance against multiple antimicrobials. Objectives: This study assessed 101 S. isolates obtained from quarter milk with subclinical Ragusa area (Sicily, Italy). Methods: Antibiotic nine antibiotics was evaluated using Kirby-Bauer method, Minimum Inhibitory Concentration (MIC) values were measured for oxacillin (OXA)...
Staphylococcus aureus is the major cause of foodborne diseases worldwide. In this retrospective study, 84 S. strains were characterized. The collection comprises 78 isolated during 1998 and 2014 from dairy products tissue samples livestock bred for production in Sicily. One isolate was obtained a pet (dog), one an exotic animal (a circus elephant), four human isolates severe food poisoning outbreak that occurred Sicily 2015. All characterized by pulsed-field gel electrophoresis (PFGE),...
The objective of this preliminary study was to evaluate the levels selected heavy metals in hair samples Holstein dairy cows reared on agricultural soils characterized by grassland subjected anthropogenic impacts. Ninety Holstein-Friesian were enrolled and divided into six groups according farm origin. From each animal, collected order determine content aluminum, chromium, iron, copper, zinc, arsenic, cadmium, lead. One-way analysis variance applied assess statistically significant...
Clinical and subclinical ketosis (SCK) in dairy cows occurs during the lactation period frequently many herds, causing a reduction milk yield alterations quality with significant economic losses for farmers. SCK is defined as preclinical stage of characterized by an elevated ketone body level without clinical signs. Often develop first weeks even though it never goes up to critical point This study aimed evaluate prevalence Sicily assess effect treatment propylene glycol (PG) control SCK,...
Influenza D virus (IDV) is a novel orthomyxovirus initially isolated from pigs exhibiting influenza-like disease in the USA. Since then, IDV has been detected worldwide several host species, including livestock animals, whilst specific antibodies have identified humans, raising concerns about interspecies transmission and zoonotic risks. Few data regarding seroprevalence of small ruminants available to date. In this study, we assessed prevalence against ovine serum samples Sicily, Southern...
Mycoplasmas are recognized as avian pathogens, which may cause both respiratory disease and synovial infections in poultry, resulting severe economic losses. Our study aims to determine the occurrence of Mycoplasma gallisepticum (MG) synoviae (MS) among commercial rural laying hens located Ragusa province (South Italy), using a duplex real time PCR. Four hundred tracheal swabs were collected from seven (200 swabs) 25 farms without any clinical history. Out 400 collected, 50 (12.5%) 93...
Marek's disease is widely controlled by vaccination programs; however, chickens are not totally protected, especially immediately after the when a strong challenge could interfere with effectiveness of in absence proper biosecurity practice. This case report describes occurrence (MD) observed breeder chicken flock reared southeast Sicily. MD outbreak occurred from 32 to 47 weeks an increase weekly mortality rate (+0.4-0.6%). Overall, related was about 6% at end cycle. Carcasses found during...
The present study assessed dairy cow welfare through the application of Italian National Animal Welfare Reference Center (CReNBA) checklist in 36 farms located Ragusa (Italy) subjected to two different management conditions, housing with free access pasture (Group 1, n = 17) and indoor 2, 19). Five areas investigation were considered: Area A, “Farm personnel”; B, “Facilities equipment”; C, “Animal-based measures”; D, “Inspection microclimatic environmental conditions alarm systems”; E,...
During a 6 week trial in summer, 3 homogeneous groups, each consisting of 5 Comisana ewes and Rossa Mediterranea goats, grazed watered forage resources during day (D) or night (N), were housed indoor supplied with mowed (H). Maximum THI peaked at 94 the end July, herbage was almost constantly higher 80. Milk yield N than D H whereas produced more milk group, but their only period highest values. The lower urea goat milk, casein ewe seem to indicate better efficiency dietary nitrogen...
Summary A quantitative risk assessment ( RA ) was developed to estimate haemolytic‐uremic syndrome HUS cases in paediatric population associated with the consumption of raw milk sold vending machines Italy. The historical national evolution phenomenon since 2008, when consumer interest started grow, and after 7 years marketing adjustment, is outlined. Exposure based on official Shiga toxin‐producing Escherichia coli O157:H7 STEC microbiological records samples from monitored by regional...
In the present study, we aimed at assessing influence of breed and feeding system on bovine milk profile betaines carnitines capacity in counteracting inflammatory endothelial cell (EC) damage induced by interleukin (IL)-6. first experimental design, two breeds were chosen (Holstein vs. Modicana) to investigate biomolecule content antioxidant dairy products. second systems (pasture total mixed ratio) tested only Holstein evaluate possible effect functional Finally, bulk from designs was used...
Bovine besnoitiosis is a parasitic disease caused by the protozoan Besnoitia besnoiti, leading to infertility in bulls and abortions cows. In Italy, it considered an emerging disease, recently introduced importation of animals from Spain France. last decade, many outbreaks have been reported confirmed native cattle, mostly northern central Italy. This study reports on autochthonous outbreak bovine two nearby farms located northwestern Sicily. A 15-month-old Limousine bull born farm showed...
The spread of multidrug resistant (MDR) Salmonella strains, along the poultry supply chain, can represent a relevant threat to human health. This study aimed evaluate prevalence and antimicrobial resistance spp. isolated from meat for consumption. Between 2019 2021, 145 samples were analyzed according ISO 6579-1:2017. strains identified by using biochemical-enzymatic assays serotyping, Kauffmann-White-Le Minor scheme. antibiotic susceptibility tests determined Kirby-Bauer method. Forty...
The emergence of multidrug resistance among Enterobacteriaceae in livestock poses a serious public health threat. Escherichia coli, usual host intestinal microbiota, is recognized also as etiological agent numerous infections widespread both humans and animals. colibacillosis one the most reported zoonoses worldwide, typically treated with antibiotics primary stages. This strategy has promoted onset antibiotic-resistant serotypes E. reducing effectiveness therapeutic treatments contributing...
The values for basal serum cortisol concentrations of horses are available in many studies. However, there limited data about donkeys. present study aimed to determine the baseline cortisol, evaluate influence age and pregnancy on its levels, correlate with leucocyte profile, cholesterol, triglycerides. Serum samples were collected from 97 healthy Cortisol was analyzed by chemo-luminescent assay. median 2.5th 97.5th percentiles measured calculated all donkeys 5.64, 3.40, 10.54 µg/dL,...
Abstract Introduction The aim of the study was to investigate relationship between biosecurity as scored on Italian National Animal Welfare Reference Centre (Centro di Referenza Nazionale per il Benessere Animale – CReNBA) checklist and prevalence Mycobacterium avium subsp. paratuberculosis , Chlamydophila abortus Neospora caninum dairy farms located in Ragusa, Italy. Material Methods used assign an animal welfare score 31 farms. Twenty-one with a moderate (>33%, <66%) formed group 1,...
Abstract Background The standard exercise stress test (ET) provides direct measurement of the load tolerated by subject, but cardiopulmonary (CPET) in addition to work also corresponding oxygen consumption. Objective aim present study was estimate differences between estimated consumption based on and one directly measured with CPET, highlight quantify inaccuracies indirect its consequences rational prescription physical activity. Material method tests performed 7544 males from January 2007...
