Slow-cooled stallion spermatozoa, with and without seminal plasma removed by centrifugation, were diluted in Kenney's extender (KE) containing nonfat dry skim milk with glucose and antibiotics or in KE supplemented by adding a modified high-potassium Tyrode's medium (KMT). Four ejaculates from each of four stallions were collected and divided factorially across these four treatments. Percentage...

Gas-phase singly protonated organic molecules of mass 410 Da (Alexa Fluor 350) have been cooled from ambient temperature to the hundred millikelvin range by Coulomb interaction with laser-cooled barium ions. The molecules were generated by an electrospray ionization source, transferred to and stored in a radio-frequency trap together with the atomic ions. Observations are well described by mole...

Bangladesh possesses a tropical goat breed popularly known as Black Bengal goat. They are dwarf in size and noted to be famous for their adaptability, fertility, prolificacy, delicacy of meat and superior skin quality (Husain et al. 1996). It is well adapted to hot and humid climate and usually produces twins and triplets. However, it has been observed that there exists sizeable genetic variati...

The aim of this study was to investigate the effects of storage of semen in different commercial extenders on the pre-freezing and post-thawing quality of boar spermatozoa. Semen was diluted in BTS, Androhep (AH) and Gedil (GD), stored for 24 h at 17°C, and then frozen in accordance with the cryopreservation protocol. Analyses of the quality of spermatozoa included: motility, normal apical ridg...

Semen extenders based on egg yolk and milk have been widely used in seminal preservation. However, they present health risks due to the transmission of pathogens. Therefore, new studies emerged seeking for a diluent vegetable origin, capable guaranteeing sperm quality eliminating risk contamination. In light above, meta-analytical review was conducted determine effect coconut water as extender ...

in this research, effect of bovine serum albumin (bsa) on motility and fertility of indigenous rooster spermatozoa was evaluated using 20 and 48 indigenous roosters and hens, respectively. semen was collected and pooled. in the first experiment, the pooled semen was diluted and divided into four aliquots.the treatments were included the diluted semen without bsa and with 1% bsa; in each group, ...

This study was carried out to identify the suitable buffer for cryopreservation of buffalo semen. Semen was collected with artificial vagina (42 degrees C) from four buffalo bulls. Split pooled ejaculates (n=5), possessing more than 60% visual sperm motility, were extended at 37 degrees C either in tri-sodium citrate (CITRATE), Tris-citric acid (TCA), Tris-Tes (TEST) or Tris-Hepes (HEPEST). Sem...
