this study was conducted to investigate the effects of the medicinal plant yarrow (achillea millefolium l.), a probiotic (primalac) and an antibiotic (virginiamycin) on gastrointestinal tract (git) characteristics, microbial populations, immune response, serum lipids and growth performance of broiler chickens. a total of 250 one-day old male broilers (ross 308) were randomly allocated to 5 trea...

Effect of ethanolic extract of propolis, royal jelly, honey and bee pollen in comparison with virginiamycin (as growth promoter antibiotic) as regards the performance and immune system of Japanese quail were assessed. We used 256 mixed-sex quail chicks in a completely randomized design by eight treatments, including control, ethanolic extract of propolis 1000 (PE1) and 5000 (PE2) mg kg-1</...

DOI: 10.21276/sjams.2017.5.9.49 Abstract: Evolvulus alsinoides Linn. Is a medicinal plant that belongs to the family convolvulaceae. This study seeks to evaluate the effects of the aqueous extract of Evolvulus alsinoides Linn. on sperm parameters and the testis. A total of fifty (50) Wistar albino rats weighing 135-150g were used in this research. The rats were divided into five (I-V) Groups of...

ABSTRACT: Gingivitis is an infectious inflammatory process that generates local and systemic conditions, compromising the masticatory capacity of animals. Virginiamycin controls prevents gingivitis necrotizing in cattle. However, interaction effect with different sera salivary elements remain unknown. The present 6-month longitudinal study evaluated hematological, metabolic, buffering profiles ...

The effects of increasing aflatoxin B1 concentration (0, 0.75, 1.5 mg/kg) on broilers with or without necrotic enteritis or virginiamycin were determined. In the 23-d study, 22 male Cobb 500 chicks per pen were allotted to 12 treatments (3 × 2 × 2 factorial arrangement) with 8 replications. Intestines of 5 birds per pen were examined for lesions on d 21. Birds were allowed to consume feed and w...

in order to investigate effects of addition of salvia mirzayanii essence and comparison with antibiotic an experiment was conducted as dietary a completely of the randomized design with 5 treatments, and 5 replicates with 12 chickens per replicate for 42 days with treatments control, virginiamycin antibiotic 10% (100 ppm) and three levels of s. mirzayanii essence (200, 400 and 600 ppm). weight ...

In spite of a global concern on the transfer of antibiotic resistances (AR) via the food chain, limited information exists on this issue in species of Leuconostoc and Weissella, adjunct cultures used as aroma producers in fermented foods. In this work, the minimum inhibitory concentration was determined for 16 antibiotics in 34 strains of dairy origin, belonging to Leuconostoc mesenteroides (18...

A research study was conducted to evaluate the effects of three herbal extracts and an antibiotic –virginiamycinon growth performance, immune system, blood factors and selected intestinal bacterial populations in broiler chickens. A total of four hundred and eighty 1-day old male broiler chicks were assigned to the basal diet (control) , basal diet supplemented with 15 ppm of virginiamycin, bas...

to evaluate the efficiency of nanocid as growth promoter in comparison antibiotics and with organic acids on performance and intestinal morphometric characteristics of broiler chickens, 240 male broiler chicks of one dayage (ross 308) were utilized in an experiment of a completely randomized design of 4 treatments and 4 replicates. the experimental treatments included: 1) control (no additives)...
