The supplementation of antimicrobial growth promoters (AGPs) has been banned in many countries because the emergence antimicrobial-resistant pathogens poultry products and environment. Probiotics have broadly studied demonstrated as a promising AGP substitute. Our study is centred on effects multi-strain Bacillus-based probiotic product broiler production performance gut microbial profile dexamethasone-induced leaky challenge. Two hundred fifty-six chicks were hatched randomly assigned into...

Prophylactic use of antibiotics in poultry diets has been identified as a problematic practice because its potential to exacerbate the spread antibiotic resistance human pathogens. A range countries have opted completely ban animal feed. The production industries are looking for alternative ways effectively control pathogens while providing performance benefits previously secured by Here, we present evidence that oregano (Origanum vulgare) could be pathogen industry. Broiler were...

This study characterised and evaluated the phenolic composition antioxidant activity of red wine grape Vranac (Vitis vinifera L.) from southern Serbian vineyard region during ripening.Polyphenol at different harvest dates was determined by HPLC-DAD analysis.Antioxidant estimated DPPH assay.The demonstrates that variety represents important sources dietary antioxidants.The results show (+)-catechin, (-)-epicatechin procyanidin dimer B2 were most prevalent in seeds, quercetin malvidin...

The aim of the present study was to assess effects medium-chain fatty acid (MCFA) diet supplementation on growth performance, intestinal histomorphology, serum biochemistry and microflora broiler chickens. performed 180 one-day-old broilers same origin (Cobb 500 hybrid), over a 42-day period. They were fed diets supplemented with three treatments: control group (basal without supplementation); MCFA supplementation; coccidiostat supplementation. Broiler chickens MCFAs had significantly...

Abstract In the dynamic world of animal production, many challenges arise in disease control, welfare and need to meet antibiotic‐free demands. Emerging diseases have a significant impact on poultry industry. Managing gut microbiota is an important determinant health performance. Introducing precision glycans as feed additives adds another dimension this complex environment. The play pivotal roles supporting immunological processes are likely limit antibiotic usage while enhancing intestinal...

Abstract A study is reported which aims to identify the optimum contents of wood flour (WF) be introduced into styrene butadiene/chlorosulphonated polyethylene (SBR/CSM) rubber blend compounded with carbon black. range composite properties are considered including cure characteristics and mechanical properties, as well adhesion strength (rubber‐to‐metal bonding) behavior. Processing characteristic such maximum torque increases increasing concentration WF up 40 phr in SBR/CSM blend, whereas...

The purpose of this study was to evaluate the tissue response induced by bioceramical materials (BCM) implanted in rat subcutaneous tissue. Thirty two rats were assigned 6 groups, as following: control group i.e. not treated; dental ceramic (DC) implants; alfa tricalcium phosphate synthetised at 22 MPa (αTCP22) and 45 (αTCP45); hydroxyapatite (HAP22) (HAP45). Contra lateral sides all test animals represented blank surgically incisied paravertebral sockets. experimental groups received...

The objective of this study was to examine the effect dietary energy supplementation on hormones that are considered be main signals a shift in balance around parturition. Sixty dry cows, 15 days before calving, were chosen and divided into two eaqual groups: control experimental (GLY). Both groups fed standard ration balanced accordance stage productivereproductive cycle. Additionally, each cow GLY group given glycerol based (250 mL daily during 300 lactation period), which provided...

Background/Aim. The last decade has been profoundly marked by persistent attempts to use ex vivo expanded and manipulated mesenchymal stem cells (MSCs), as a tool in different types of regenerative therapy. In the present study we described immunophenotype proliferative differentiation potential isolated from pulp remnants exfoliated deciduous teeth final phase root resorption. Methods. initial adherent cell population five donors was obtained outgrowth method. Colony forming unit-fibroblast...

The effects of propylthyouracil (PTU) induced hypothyroidism rats during pregnancy and lactation on offspring ovarian development maturation were studied. Thyroid hormones thyroid stimulating hormone (TSH) concentrations determined using the radioimmunoassay method in order to verify hypothyroid status treated mothers their two months old pups. ovaries processed for light microscopy analysis day first estrus after 60th age. Histological including follicle count was performed serial sections...

Herbs and spices have been used throughout human history for their medicinal qualities. The advent of cheap readily available medicines lessened the need herbs as traditional medicines, however, they are rapidly regaining popularity with rising interest general population in health, natural products nutrition. alternative antimicrobial properties, such spices, has also come to forefront light recent bans antibiotic use livestock industry, including poultry industry. This large scale presents...

Polyphenols are widely distributed in the plant kingdom, including grape (Vitis vinifera L.), and extracted during winemaking. Because of their potential beneficial health, free radical scavenging antibacterial activities some red wines from Zupa viticulture winemaking region Serbia produced old autochthonous cultivars: Vranac, Kratosija, Prokupac, Merlot, Pinot Noir, Gamay cultivars originated France. The results showed that antioxidant activity was highly correlated with content total...

Pathogen control is re-emerging as a significant challenge to the health of both humans and animals. The livestock industry in process massively replacing in-feed antibiotics with organic production friendly plant-based products. Nutrigenomics science effects food constituents on gene expression shedding more light benefits detrimental side-effects feed additive prolonged consumption host, indicating need understand feed-host interactions their influence host disease profile. In this study,...

The concept of designer microbiota in chicken is focused on early exposure the hatchlings to pathogen-free inoculum, limiting access harmful and pathogenic microorganisms, thus promoting colonisation gut with beneficial natural poultry microbiota. In this study, we controlled intestine broiler chickens a large-scale industrial setting via at-hatch administration commercial product containing highly diverse originating from caecum. treatment significantly transformed membership crop,...

Abstract Induced prenatal hypothyroidism in rat pups leads to accelerated primordial follicle assembly and premature follicular atresia with ovary failure. This work investigates the influence of maternal induced 6-n-propyl-2-thyouracil (PTU) on number morphology oogonia/oocytes newborn light transmission electron microscopy. Expression apoptosis autophagy markers were examined using immunohistochemistry. Hypothyroid had a decreased mitotic resting oogonia, while altered was increased....

Abstract Maternal hypothyroidism in its overt form affects skeletal development of the offspring, but these data are not available for subclinical which is becoming very frequent among pregnant women. We hypothesized that rat dams, infl uences process offspring endochondral ossifi cation affecting proliferation and differentiation chondrocytes, osteoclasts osteoblasts pups. Seven-day-old male pups (n=18) derived from control dams treated with a low dose (1.5 mg/L) or high (150...

Abstract This study aimed to measure the total arsenic content deposited in ovaries of three consecutive generations mice. The animals were treated with two different concentrations determine whether histological changes caused ovaries. control group mice received tap water, whereas experimental groups given dissolved (III)-oxide. both increased each generation. highest was recorded third generation second group. Between generation, significant differences average number corpora lutea and...

Abstract Osteoarthritis (OA) in horses often affects the metacarpal/metatarsophalangeal (MCP/MTP) joints and its detection early stages is crucial for effective management.
