The Effect of Resveratrol Antioxidant in Nano Liposome and NLC Forms Rooster Semen Extender During Storage at 4˚C

The reproductive characteristics and seminal carnitine and acetylcarnitine content as well as carnitine acetyltransferase activity of young Maremmano stallions (n=25) are reported. The stallions were subjected to semen collection in November and January; in each trial two ejaculates were collected 1h apart. The total motile morphologically normal spermatozoa (TMMNS) and the progressively motile...

Artificial insemination (AI) is the preferred method for reproduction in the majority of the intensive pig production systems Worldwide. To this end, fresh extended ready-to-use semen doses are either purchased from AI-centres or produced by boars kept on-farm. For profitable semen production, it is necessary to obtain a maximum amount of high quality semen from each boar. This paper reviews cu...

A calcium-free Krebs Ringer solution, supplemented with 1 mg/ml glucose, with or without 0.025% formalin, was used to dilute freshly collected ram semen on a 1:l basis. The treated semen was inseminated into the cervix of Merino ewes either within 60 minutes of collection or after storage at 5OC for 24 h. Although the Ringer-formalin diluent always caused complete immobilisation of the spermato...

Background: Semen cryopreservation is the most important section of artificial insemination programs; it allows preservation of semen fertility for a long time. Materials and Methods: The aim of the present study was to detect the effect of in vitro supplementation of 4-hydroxy Tempo on fresh and frozen spermatozoa quality of buffalo bulls. Five healthy buffalo bulls (5 ejaculates from each bul...

The purpose of this study was to evaluate the probable effects of the vitamin E addition in different levels to the extender of chicken semen on spermatozoa quality during storage of semen at 4°C for 0, 3, 6, 10 and 24 hours. Eight young Ross broiler breeder strain 308 roosters were used in this experiment. The collected semen from all roosters was mixed together and diluted with modified a Rin...

The study describes the standardization of a suitable semen cryopreservation protocol for the first time in mithun (Bos frontalis) and birth of the first mithun calf through artificial insemination. The semen samples were collected from adult bulls through the rectal massage method and cryopreserved in liquid nitrogen using tris-egg yolk-glycerol diluent. The diluted semen samples were packaged...
