The aims of this study were firstly to evaluate the pathogenicity an Italian isolate QX strain infectious bronchitis (IB) virus using 1-day-old female specific pathogen free chicks (layer type) and commercial broiler type chickens, secondly assess level protection induced in these birds by a vaccination programme including IB Massachusetts 4/91 serotype live attenuated vaccines. Unvaccinated showed clinical signs varying severity, predominantly affecting upper respiratory tract. Vaccinated...
The aim of this study was to investigate the effects two feed supplements on rumen bacterial communities heifers fed a high grain diet. Six Holstein-Friesian received one following dietary treatments according Latin square design: no supplement (control, C), 60 g/day fumarate-malate (organic acid, O) and 100 polyphenol-essential oil (P). Rumen fluid analyzed assess microbial population using Illumina sequencing quantitative real time PCR. P treatment had highest number observed species (P <...
Following the avian influenza epidemics that occurred in Italy between 1997 and 2003, Italian Ministry of Health collaboration with veterinary authorities promoted, funded implemented a national surveillance programme. The main objectives effort were to identify viruses circulating wild birds investigate role backyard poultry flocks dynamics infection densely populated area. Over 2 years (2004 2006), 164 4083 (mainly migratory Anseriformes Charadriiformes) sampled three regions North Italy....
From October 2021 to January 2022, different incursions of clade 2.3.4.4b H5N1 HPAIV (Highly Pathogenic Avian Influenza Virus) occurred in several Italian regions with its main diffusion Densely Poultry Populated Areas (DPPAs) north-eastern Italy. Monitoring and control activities applied the affected area clearly evidenced that turkeys broilers were most species, although flocks at times resulted infected absence increased mortality and/or clinical signs. Thus, an approach based on sampling...
Abstract Background Ruminal acidosis is responsible for the onset of different pathologies in dairy and feedlot cattle, but there are major difficulties diagnosis. This study modelled data obtained from various blood variables to identify those that could indicate severity ruminal acidosis. Six heifers were fed three experimental rations throughout periods. The diets characterised by starch levels: high (HS), medium (MS) low starch, as control diet (CT). pH values continuously measured using...
The aim of this study was to determine the ability two feed additives, a fumarate-malate (FM) and polyphenol-essential oil mixture (PM), in attenuating drop ruminal pH metabolic immune response resulting from an excessively high grain diet. Six heifers were used 3 × Latin square experiment fed low starch (LS) diet for 14 d, followed by (HS) 8 d (NDF 33.6%, 30.0% DM). In last 5 days each period, barley meal added decrease rumen pH. During HS feeding all animals randomly assigned one following...
The aim of this study was to compare a fully slatted concrete floor (concrete (CS)) with the same on which synthetic rubber slats were placed (rubber (RS)) as housing solution for finishing beef cattle. present involved five commercial cattle farms in at least three pens kept slatted, and an equal number cover floor, tightly matching gap profile allow drainage manure. A total 326 bulls used (153 CS 173 RS), regardless treatment animals housed groups 6 12 bulls/pen space allowance 3.1±0.2...

Twelve olstein‐ F riesian cows were assigned one two experimental groups fed according a cross‐over design. Diets isoenergetic isonitrogenous characterised by same ADF ,...
ABSTRACT: Horseweed (Conyza spp.) is a weed with considerable presence and frequency throughout Brazilian crops, as well presenting difficult chemical control. The objective of this study was to evaluate the efficiency herbicide management, through single sequential applications, in controlling Conyza spp., at two development stages 4 6 leaves (3 5 cm) 20 (15-20 cm). analyzed variables were: control percentage (7, 14, 21, 28 days after application), dry matter content (28 application)...
Highly pathogenic avian influenza (HPAI) viruses cause viraemia and systemic infections with virus replication in internal organs muscles; contrast, low pathogenicity (LPAI) produce mild mortality rates local replication. There is little available information on the ability of LPAI to or presence general muscles infected turkeys. The aim present study was determine HPAI H7N1 reach muscle tissues following experimental infection efficacy vaccination preventing meat localization. potential...
Following the avian influenza (AI) epidemics occurring in different areas of world, a surveillance program funded by Italian Ministry Health was implemented. In framework this program, an investigation wild birds carried out to assess circulation AI viruses their natural reservoir. More than 3000 samples, mainly cloacal swabs, were collected from migratory belonging orders Anseriformes and Charadriiformes. Samples screened means real-time reverse transcriptase polymerase chain reaction...
We performed an experimental infection of 21- and 70-day-old meat turkeys with early human isolate the 2009 pandemic H1N1 influenza virus exhibiting alpha-2,3 receptor binding profile. Virus was not recovered by molecular or conventional methods from blood, tracheal cloacal swabs, lungs, intestine muscle tissue. Seroconversion detected in a limited number birds homologous antigen only. Our findings suggest that its present form, is likely to be transmitted does therefore represent animal...
Avian influenza represents one of the greatest concerns for public health that has emerged in recent times. Highly pathogenic avian viruses belonging to H5N1 subtype are endemic Asia and spreading Europe Africa. Vaccination is now considered a tool support eradication efforts, provided it appropriately managed. This study was carried out establish degree clinical protection reduction viral shedding induced by high-specification, commercially available vaccine different lineage containing...
The study aimed at evaluating the effect of a daily dose 14 g choline administrated by using soy lecithins (LC group), by-product biodiesel production process, compared to 25 chloride microencapsulated with hydrogenated vegetable oils (RPC group) on performance and milk quality dairy cows. A total 12 mid-lactating Holstein Friesian cows were assigned one two experimental groups fed according cross-over design (2 diets × 2 periods) isoenergetic, isofibrous isonitrogenous diets, characterized...
ABSTRACT: This study aimed at evaluating the agronomic performance of Intacta RR2 soybean submitted to application glyphosate doses in post-emergence. For this, two experiments were conducted locations (Palotina and Marechal Cândido Rondon - Paraná state). Applications carried out with increasing rates (0, 720, 1,440, 2,160, 2,880, 3,600, 4,320 g a.e. ha-1), constituting seven treatments an experimental design randomized blocks four replications, totaling 28 plots for each location.
