Selenium is an important mineral, required for many functions within animals, where it interacts with vitamin E, maximizing the efficiency of as antioxidant. In chickens, adequate intake organic forms Se may be linked to reduced drip loss in final meat and improved feather production. The present trial was conducted examine impact feeding (Sel-Plex, Alltech Inc., Nicholasville, KY) broilers on their productive performance, growth, characteristics. Birds fed 0.3 ppm had decreased from breast...

Subsequent to banning of use antibiotics as growth promoter sin poultry nutrition, numerous studies turned finding alternative solutions, i.e. other, natural substances, which would have positive effect on chicken and feed conversion. Today, several groups these additives are in use, most often probiotics, prebiotics, enzymes, acidifiers, antioxidants phytogene additives. Considering that each the stated has its own specificities, objective this work was present main mechanism their action...

Radiotherapy-induced toxicity is a major dose-limiting factor in anti-cancer treatment. Ionizing radiation leads to the formation of reactive oxygen and nitrogen species (ROS/RNS) that are associated with radiation-induced cell death. Investigations biological effects fullerenol have provided evidence for its ROS/RNS scavenger properties vitro radioprotective efficiency vivo. Therefore we were interested evaluate human erythroleukemia line. Pre-treatment irradiated cells by exerted...

Abstract. The trial involved 684 Cobb 500 broiler chicks in order to investigate the effects of probiotics and phytogenic additives on performance, gut morphology cecal microbial concentrations. Birds were assigned three treatments: control feed, treatment with addition feed water blend feed. results showed a significant improvement (P<0.01) body weight gain numerical, but non (P>0.05) conversion ratio by adding both phytogenics There no statistically differences among treatments...

Abstract The effects of short‐term genistein exposure on ovarian folliculogenesis in immature rats were examined stereologically. To determine whether acts as an estrogen agonist or antagonist, the results compared with 17α‐ethynylestradiol. Immature female received 50 mg/kg/bw dimethyl sulfoxide subcutaneously daily for three consecutive days from 18 to 20 days. second group was injected 1 μg/kg/bw 17α‐ethynylestradiol olive oil same schedule. Each had a corresponding control. Genistein...

A trial was conducted to investigate whether, and if so what extent, the combined supplementation of vitamin E, C, selenium superior their sole concerning oxidative stress induced by a high n-3 dietary polyunsaturated fatty acids (PUFA) intake in broilers. Four hundred 21-day-old Ross 308 male broilers were allocated 5 experimental groups fed following linseed oil (5%)-enriched finisher diets: Cont (no supplement), +E (200 IU E/kg feed), +C (250 mg C/kg +Se (0.2 selenium/kg or +ECSe...

Enzyme supplementation of diets enhances broiler performance by improving some the basic production parameters such as average feed intake, conversion ratio, or weight gain. The enzyme NSPase is commonly used in containing high levels viscous cereals barley, oat, wheat, sorghum. use with different sunflower meal has been not extensively explored. experiment was carried out to evaluate effects inclusion grower and finisher supplemented enzymes (cellulase, β-glucanase, xylanase) on...

This study was conducted to evaluate the impact of litter type and treatment with enzymatic-bacterial production incidence severity footpad dermatitis consequently on behavior broiler chickens. A total 1,200 one day-old Ross 308 broilers were randomly allocated 4 treatments replicates in 2 x factorial design. The first factor physical form straw (chopped approximately cm or un-chopped) second addition product applied directly straw. Each replicate consisted 75 as-hatched birds per pen....

Abstract. This study was conducted to evaluate the impact of litter amendment (microbiological product – Micropan complex) and straw size (unchopped chopped straw) on pH, moisture level, ammonia emission, footpad dermatitis in broilers. A total 1200 1-day-old Ross 308 broilers were randomly allocated four treatments (2 × 2 factorial arrangement), with replicates per treatment. Each replicate consisted 75 as-hatched birds pen. The first factor wheat (C) or unchopped (U) second (WM) without...

Cardioprotective effects of fullerenol C60(OH)24 nanoparticles (FNP) were investigated in pigs after a single treatment with doxorubicin (DOX). Semithin and ultrathin sections myocardial tissue routinely prepared for transmission electron microscopy analyzed. Extensive intracellular damage was confirmed cardiomyocytes DOX-treated animals. By means ultrastructural analysis, certain degree parenchymal degeneration even animals treated FNP alone, including both the oral intraperitoneal...

Stocking density is considered one of the most important factors for welfare broilers. This paper continuation study in order to obtain full evaluation impact different broiler stocking densities on production performance, condition legs and body feathering, as indicators but also productivity quality produced chickens. The effect three (20, 15 10 birds/m2) was investigated 4 repetitions broilers genotype Hubbard at age 3 6 weeks. At weeks 20 birds/m2 resulted significantly lower growth...

Evaluation of neuroprotective effects hypothermia, erythropoietin and their simultaneous use after perinatal asphyxia in newborn rats.Hysterectomy was performed to Wistar female rats on the last day gestation. Perinatal induced by submersion uterus containing pups saline for 15 min. After resuscitation, were randomized into 4 groups, animals each: G1 - asphyxia; G2 + hypothermia (rectal temperature 33 °C 1 h); G3 (Darbepoetin-α 2.5 μg, intraperitoneally) G4 hypothermia. Pups sacrificed 7th...

In modern poultry production, foot pad dermatitis (FPD) represents one of the main problems on broiler chicken legs with significant affect animal welfare and performance. This problem is not solved by using straw as litter. Different treatments are needed to eliminate adverse effects this material The most widely used method improve quality litter chopping application microbial products that. These procedures can decrease moisture in reduce population microorganisms whose activity produces...

The aim of this paper is to examine the effect different sound stress duration on adrenal gland broiler chickens age. experiments were conducted 90 HYBRO chickens, divided into nine groups (each group consisting 10 birds) by age and lenght duration. exposed in attenuated building using a fire alarm bell (95 dB) for sessions lasted 120 min every day. histological structure was analyzed light microscopy. results indicate that sensitive kind as stressor could introduce organism reaction....
