in this research 400 ross 308 breeder fertile eggs were weighed at day 16 of incubation and evenly distributed into 4 treatments with 4 replicates per treatment and 25 eggs per replicate in a crd design. on day 18 of incubation, 1 ml of an in ovo feed solution including: i) carbohydrate (cho), ii) amino acid (aa), and iii) butyric acid solution in 0.5% saline was injected into amniotic fluid of...

We evaluated the fects of different levels dietary silver nanoparticle (AgNP) powder on performance, intestinal microflora, carcass traits and blood parameters broiler chickens. Three hundred seven-day-old Ross chicks were randomly divided into five groups, each group replicated three times with 20 birds per replication. Chickens fed basal diet 2.5, 5, 10 mg AgNPs kg feed. Dietary inclusion imp...

BACKGROUND Acute rejection (AR) remains a life-threatening complication after orthotopic liver transplantation (OLT) and there are few available diagnostic biomarkers clinically for AR. This study aims to identify intestinal microbial profile and explore potential application of microbial profile as a biomarker for AR after OLT. METHODS The OLT models in rats were established. Hepatic graft h...

The current study investigated the efficacy of a probiotic mixture on ameliorating heat stress-induced impairment of intestinal microflora, morphology, and barrier integrity in broilers. The probiotic mixture contained Bacillus licheniformis, Bacillus subtilis, and Lactobacillus plantarum. Three hundred sixty 21-d-old Ross 308 male broilers were allocated in 4 experimental treatments, each of w...

this experiment was carried out to study effect of supplementary multi enzyme (0, 4 gr per 100 kg of diet) to corn-soybean meal based diets with different levels of tomato pomace (tp, 0, 2, 4, 6 and 8 %, respectively) on chick performance and carcass traits. four hundred and eighty 480 day-old chicks (ross-308) were employed [four replicates (n=20)] in a completely randomized experimental desig...

this study was carried out to evaluate the effect of onion extract on growth performance, carcass characteristics and some blood metabolites in ross and cobb broiler chickens. one hundred sixty, 1-d-old broiler chickens (mean initial weight: 36.5 ± 1 g) of male sex (ross-308 and cobb) were randomly conducted as randomized complete design with 4 treatment and 4 replication. the experimental grou...

This experiment was conducted to evaluate the supplemental effects of a novel protease produced from Bacillus subtilis in low crude protein (CP) corn distiller dried grain with solubles (cDDGS) based diets on growth performance, carcass attributes, nutrients digestibility, blood chemistry, and intestinal histomorphometry broiler chickens. One hundred sixty, one-day-old chicks were randomly allo...

In this study, 180 aut of 986 primary school children of Absard were evaluated for the presence of intestinal parasitic infections. Direct smears of one stool sample for each public were used in this study. The samples were selected from one urban and two rural areas. Afghan immigrants were also included in the study. Among study population, 69 % were infected by intestinal parasites. The most...

lactobacilli, like the other gut commensal bacteria, are well known for their use in poultry nutrition and for their probiotic properties. however, little is known about their interaction with the gastro-intestinal tract when administered in vivo. to specifically monitor the passage of lactobacilli after administered in hatchery, lactobacillus plantarum was transformed with the recombinant vect...
