this experiment was carried to find out the effects of foliar fertilization and growing media on some of vegetative and reproductive traits of the new vegetable pepino (solanum muricatum) in a pot culture in outdoor space during five month period in mashhad. foliar fertilization treatments were used in this study including foliar fertilization once every three weeks, once a week and control (no...

The effects of K. africana fruit (Lam. Benth), family bignoniaceae, were investigated on the sperm quality of C. gariepinus, (mean body weight, 396.05±7.04). Five diets with crude protein of 40% were formulated with different inclusion levels of K. africana powder. D1 (control) has 0 g/kg of the powder, while D2, D3, D4 and D5 has 50, 100, 150 and 200 g/kg of the K. africana powder. A total of ...

In this study, the benefits of using the first Iranian made GnRHa[D-Ala6 des Gly10] mGnRH ethylamide, to induce spermiation in male rainbow trout, Oncorhynchus mykiss, were evaluated, In addition, its effect on acceleration and synchronization, quality and quantity of milt and the plasma Testosterone (T) fluctuations were examined. For these purposes, 40 non-spermiating male rainbow trouts wer...

The study aimed to evaluate the effect of inorganic mercury (iHg) on sperm quality, embryos, and larvae Prochilodus magdalenae. Two experiments were carried out. In experiment 1, semen was activated with contaminated water at different iHg concentrations (0.0, 25, 50, 100 µg/L) kinetics analyzed a computer-assisted analysis (CASA) system. second trial, 2 g oocytes fertilized 50 µL milt, µg/L), ...

Ž . In three separate experiments, non-spermiating male Atlantic salmon Salmo salar were Ž . injected with a commercial salmon gonadotropin releasing hormone analog GnRHa preparation Ž . or vehicle propylene glycol . After 6 days, fish were also injected with 17a-hydroxyprogesterone Ž . Ž . 17P , 17a ,20b-dihydroxy-4-pregnen-3-one 17,20bP or vehicle. Injections were repeated on day 7, and after...

Quality of fresh milt of grey mullet Mugil cephalus Linnaeus, 1758 was assessed based on motility grade, motility duration, sperm count and seminal plasma osmolality. Freshly collected milt from live males (n=17) were examined individually for motility assessment. Motility grade was four in fifteen samples whereas three in other two samples analysed. Other sperm quality parameters such as motil...

To examine how territorial males counter reproductive parasites, we examined the paternity of broods guarded by territorial males using 5 microsatellite loci and factors that determine siring success in a wild population of the Lake Tanganyika cichlid Lamprologus lemairii. Females enter rock holes (nests) and spawn inside, and territorial males release milt over the nest openings. Sneakers atte...

To assess the risk posed by vertical transmission of viral haemorrhagic septicaemia virus, VHSV, in rainbow trout ova, an experimental challenge study was conducted. Prior to the fertilisation process samples of milt and/or ova were infected with VHSV. Virus was not detected from either the fertilised ova or hatched fry. These results indicate that the risk associated with VHSV vertical transmi...

Background: Although in vitro fertilization (IVF) has been found to bypass the inhibitory effect of high levels of antisperm antibodies on sperm motility, fertilization rates are reduced in approximately 40% of the attempts. In this study, we investigated the relationship between antisperm antibodies measured by the direct mixed agglutination reaction (MAR) and the fertilization rate in inferti...
