Cultivar evaluation and mega‐environment identification are the most important objectives of multienvironment trials (MET). The objective this study was to explore effect genotype × environment interaction on grain yield 19 barley ( Hordeum vulgare L.) genotypes via GGE (genotype plus environment) biplot methodology. Experiments were conducted using a randomized complete block design with four replications for 3 yr at 10 locations. analysis identified three mega‐environments in Iran. first...

Fertility has a great impact on economic outcome in poultry sector. However, several physiological stressors such as aging adversely affected fertilization capacity and hatching quantity quality. This study investigated the effect of dietary supplementation different sources levels inorganic organic selenium semen quality reproductive performance aged broiler breeder roosters. A total thirty-six 50-wk-old Ross 308 roosters were randomly allocated to 6 groups fed with selenium. Treatments...

Newcastle disease virus (NDV) strains, while falling under a single serotype, are classified into distinct genotypes. Genotype VII virulent NDVs pose significant threat to poultry due their association with high mortality rates and economic losses. This study aimed evaluate the efficacy of three commercial live vaccines based on genotype II against NDV (vNDV) in specific pathogen-free (SPF) chickens, Forty one-day-old chickens were randomly divided four groups (n=10) inoculated one dose each...

1. Deleterious effects from the freeze-thawing process on post-thawed sperm quality attributes are main limiting factors in cryopreservation. The current study was conducted to determine effect of semen extender containing zinc oxide (ZnO) post-thaw rooster indices.2. Semen samples six, 60-week-old broiler breeder roosters were collected weekly during five successive weeks. mixed and divided into three equal parts diluted with different levels ZnO; 0 (ZnO-0), 1 (ZnO-1) or 2 (ZnO-2) µg/ml....

1. Decreased semen quality is an underlying contributor to age-related subfertility in broiler breeder roosters. This study investigated the effects of dietary curcumin (derived from turmeric) supplementation as antioxidant source on and fertility 2. Twenty-eight Ross 308 roosters were randomly allotted four groups with seven birds each fed a standard diet supplemented different levels at 0 (C0), 10 (C10), 20 (C20) 30 (C30) mg/bird per day 48 through 61 weeks age. Body weight traits...

This experiment was conducted to study variations of serum testosterone and seminal characteristics Markhoz male goats. Blood samples were obtained via jugular vein, semen collected by using an artificial vagina from 14 fertile goats (2-3 years age), at 15-day intervals starting on 15 July ending 30 October 2010 (during breeding non-breeding season). Semen volume, total sperm (volume×concentration), live (%), abnormal (%) pH significantly superior during the late summer early autumn...

ABSTRACT BACKGROUND: Celiac disease is an enteropathy caused by dietary gluten. The combination of serologic, genetic and histologic data has led to description other categories this disease. OBJECTIVE: There are a number patients with iron deficiency anemia (IDA) that do not respond treatment may be repeated for many times, Therefore, we aimed investigate celiac in group. METHODS: In cross sectional transverse prospective study from August 2011 February 2013, Pediatric care clinic...

Saffron (Crocus sativus L.) is among the world's most expensive crops; nevertheless, it struggles to compete with weeds. Non-chemical farming practices, such as intercropping and reduced irrigation, can help decrease weed problems. Therefore, this study aimed evaluate changes in density, biomass diversity under saffron-chickpea system two irrigation regimes. The study's treatments included regimes, namely one-time conventional (carried out four times from October through May), six planting...

Objective:Programmed cell death protein 1 (PD-1) gene encodes an inhibitory surface receptor involved in the regulation of T-cell function during immunity and tolerance. This study investigates PD-1 polymorphism patients with colorectal cancer (CRC).

Japanese quail is an increasingly important bird of economic importance for commercial egg and meat production, particularly in developing countries. There a need research aimed at improving efficiency these birds during stressful challenges, such as oxidative stress. Coenzyme Q10 (CoQ10), highly functional antioxidant, protects cells against This study was conducted to determine the effects CoQ10 on reproductive performance under cadmium (Cd) challenge. A total 216 six-wk-old were randomly...

Abstract The demand for quail eggs has been increased over the last decade due to its beneficial nutritional quality characteristics; however, different and environmental stressors adversely impact of produced eggs. This study was conducted investigate whether dietary supplementation coenzyme Q10 (CoQ10) could mitigate negative cadmium (Cd) administration on egg liver histopathology. A total 162 six‐week‐old laying Japanese ( Coturnix japonica ) were randomly allotted into three experimental...

Abstract Background Acidifier are substances with antibacterial, antifungal, antimicrobial, performance and health benefits that frequently employed in feed acidification, especially poultry diet. Meanwhile, the most important factor for acidifier efficiency is proportion of different acids final product. Objectives This study aimed to investigate effect dietary supplementation a commercial on egg production histology small intestine laying Japanese quail. Methods One‐hundred sixty female...

Abstract Background Due to the more stability and a better homogenecity in immune response, use of thermoresistant vaccines different chicken types has been increased. Objective This study aimed evaluate efficacy newly developed Newcastle disease vaccine (ND.TR.IR) originating from I‐2 strain specific pathogen‐free (SPF) native broiler chickens. Methods Following determination pathogenicity indices on candidate seed, three examinations were conducted. In first experiment, 120 1‐day‐old SPF...
