The application of injectable zinc, copper, manganese and selenium (trace minerals - ITMs) at the arrival can be a strategy to boost antioxidant defences immune function, with positive effects on production performances, in fattening beef cattle. administration ITMs were tested 576 Charolaise bulls, randomly allocated, arrival, into two groups, i) control (CON); ii) Multimin (MM-Multimin®). growth performance, feed intake (FI), conversion ratio (FCR), health status evaluated. oxidative was...

Clearly, the future of beef cattle industry in United States depends on quality product. The majority calves are born spring; therefore, to have a consistent supply feeders entering feedlots and take advantage forages, variety stocker programs exist. Cattle enter feedlot at varying weights ages from different nutritional backgrounds, this variation could produce differences carcass quality. economically important measures yield grade grade. They directly related: as fatten feedlot, both...

Sixty-three bulls were distributed over 3 treatments fed SS, SY, or OH-SeMet at 0.2 mg kg−1 dry matter (DM) for 60 d. None Se sources affected growth performance carcass characteristics. showed a higher transfer than SS SY (p < 0.01). reduced shear force 0.0001), improved pH 0.001), drip losses 0.001) lipid...

Neonatal calf diarrhoea (NCD) poses a significant health challenge in cattle herds, resulting considerable economic losses and antimicrobial use. In response to the escalating threat of resistance, viable alternatives are imperative, aligning with European policies. This study evaluated in-milk supplementation chestnut quebracho tannin extract preweaning calves on performance, occurrence,

Neonatal calf diarrhoea is one of the most important health challenges in cattle herds causing substantial economic losses and antimicrobial use. Due to raising problem resistance, effective alternatives are urgently required, line with European policies. The aim this study was evaluate effect tributyrin supplementation milk replacer on diarrhoea, performance metabolic status preweaning Holstein calves. Twelve newborn calves, after colostrum administration, were randomly allotted two...

This study evaluated the functional components of hazelnut waste products (cuticles and shells) for potential use in circular economy. HPLC-HRMS ABTS assay were used to determine molecules with properties antioxidant capacity, respectively. The capacity cuticles shells was tested using two different methods extraction (EtOH 50/50 acetone 40/70) by radical cation decolorization assay. growth inhibition effect extracts against porcine O138 E. coli F18+ microdilution bacterial method confirmed...

The effects of heated drinking water on growth performance and rumen functionality in fattening beef cattle during winter were evaluated. Newly received Charolaise bulls (n = 224) allocated to two experimental groups: (i) at room temperature (RTW) (weight 408 ± 34 kg); (ii) constantly (25 °C) (HW) 405 38 kg). Growth performances, feed intake, conversion rate, intake carcass characteristics Internal reticuloruminal wireless boluses used collect pH values every 10 min. Bodyweight was not...

Conflicting findings regarding the boldenone content of bovine faeces suggest it may be synthesized de novo in emitted faeces. We tested this hypothesis by analysing uncontaminated urine, fresh and various forms dried from 10 calves (not given boldenone) liquid chromatography/tandem mass spectrometry for 17alpha- 17beta-boldenone (alpha beta BOL); 1,4-androstadiene-3,17-dione (ADD); 4-androstene-3,17-dione (AED), testosterone (T) epitestosterone (ET). Urine contained no alpha BOL, BOL or...

The effects of the partial substitution corn and soybean meals with bakery former foodstuffs (BFF) wheat wet distiller’s grains (WDGs) on environmental sustainability, production performance, health status were evaluated in beef cattle. Newly arrived Limousine heifers (n = 408) housed an intensive farm Campagnatico (Grosseto, Italy) balanced for initial weight body conformation then randomly divided two groups: (i) Traditional corn–soybean meal diet; (ii) Circular diet average as-fed 1.5 kg...

The effects of partially replacing soybean meal (SBM) with a slow-release urea source (SRU) on production performance, feed efficiency, digestibility, and environmental sustainability dairy cows were evaluated. A total 140 lactating Holstein Frisian allocated into two study groups: (i) control (diet entirely based SBM), (ii) treatment 0.22% dry matter basis (d.m.)) SRU. Milk yield, intake (DMI), conversion rate (FCR), body condition score (BCS), reproductive parameters, milk quality chemical...

The effect of a nutraceutical mixture, based on live yeast (LY), mannan oligosaccharides (MOS) and organic selenium (Se) health status, as well immune functionality growth performance in the fattening newly received beef cattle, was evaluated. A total 1036 Charolaise heifers were allocated into two experimental groups: (i) control group, without any support (n = 487; initial weight 325 ± 21 kg); (ii) treatment supplementation during first 30 days, with LY (5 g/head/day), Se (3 mg/head/day),...

European Directive 96/22/EC, which controls veterinary residues in animals, does not permit the presence of synthetic growth promoters products animal origin or livestock. Boldenone is categorized class A3 (growth -- steroids) and thus a banned substance. Testing veal urine for substances part Union statutory programme animals going into food chain. In relation to this monitoring, three studies were conducted investigate apparent promoter boldenone urine, was suspected as being caused by...

Lactobacilli the predominant microbial population (about 6 log cfu/cm 2...

Context European beef production is facing fresh challenges on various fronts: increasing public concern animal welfare; declining EU meat consumption; and, conversely, expected growth in global demand for meat. The Italian National Reference Centre Animal Welfare (CReNBA) has developed an assessment protocol collecting information about cattle welfare and biosecurity conditions, with the intention of better understanding needs disseminating best practices. Aims was applied Irish farms,...

The goal of calf feeding systems is to provide calves with optimum nutrition promote growth, health, and future milk production reduce antibiotic use which leads a need for alternatives that illness growth in dairy calves. We hypothesized live yeast would improve gastrointestinal health performance aim this study was then evaluate the effects supplementing probiotic
