Gene copy number variation is frequent in plant genomes of various species, but the impact of such gene dosage variation on morphological traits is poorly understood. We used a large population of Pop...
Soil salinization and alkalization are among the major agricultural threats that affect crop productivity worldwide, which are increasing day by day with an alarming rate. In recent years, several hal...
Water stress is one of the most important environmental stresses which can adversely affect soil fertility and plant growth in arid and semiarid regions. In this study, biochar was used as a type of s...
In this study, we investigate seedlings of Quercus castaneifolia C.A. Mey, from five different provenances for the research on leaf and crown morphological variations in relation to a light gradient ...
The effects of dietary chitosan-copper chelate (CS-Cu) on growth performance, diarrhea, intestinal morphology and epithelial cell apoptosis in weaned piglets was investigated. One hundred and sixty Du...
In the present study, role of increasing levels of Ecklonia cava (seaweed) supplementation in diets was investigated on growth performance, coefficient of total tract apparent digestibility (CTTAD) of...
The aim of this in vitro study was to determine the effect of lead chloride (PbCl2) on rabbit spermatozoa motility and morphology. Lead concentrations in the medium ranged between 0.45 and 11.17 μg/ml...
Spermatozoa morphology, ultrastructure, and spermatozoa motility traits were studied in pikeperch (Sander lucioperca) after activation in various media (AM 1 ?45mM NaCl, 5mM KCl, 20mM Tris, pH 8.5; AM...
The influence of different levels of extruded full-fat soybean (EFFSB) in the diet on growth performance, apparent ileal amino acids digestibility (AIAAD), intestinal morphology, and trypsin activity ...
In this study 120 piglets were allotted to 3 dietary treatments, negative control group, one group receiving a blend of essential oils (EO) derived from oregano, anise and citrus peels (40 mg/kg diet)...
Udder morphology traits were measured and subjectively assessed by the use of linear scores in 266 ewes of Tsigai (T), Improved Walachian (IW) and Lacaune (LC) dairy breeds. Animals were recorded repe...
The present study was conducted to evaluate the effect of the dietary supplementation of Bacillus amyloliquefaciens-based direct-fed microbial (DFM) on growth performance, nutrient utilization, intest...
Secretion of adequate levels of progesterone from a proper corpus luteum (CL), which develops out of the cells of a healthy preovulatory follicle, is a key-factor for establishment of a pregnancy. The...
In this study, the aim was to investigate the anatomy of the aortic arch arteries in mole-rats (Spalax leucodon). Six adult mole-rats were used for this purpose. Coloured latex was injected into the l...
The morphology and quality of oocytes is set during oo- and folliculo-genesis, and is completed during final maturation. Early embryonic development is associated with the morphology of the cumulus-oo...
