Semen quail-

The effect of quail semen dilution with three extenders : Lake's, Ringer's and Tyrod's on morphology and fertility trials of unstored spermatozoa was evaluated. Semen was collected twice a week by male stimulation by female method, from 60 quail males randomly divided into four groups I-IV. Semen dilution did not affect the number of live spermatozoa in total, but the number of live, morphologically normal spermatozoa depended on the diluent. The highest number of morphologically normal spermatozoa Egg fertility

Roosters and tom turkeys need to be routinely Semen quail for semen collection for several days prior to the actual AI procedure to guarantee each bird is fertile with a microscopic examination of the sperm. Because poultry semen Semne viability within 1 hour, hen insemination should begin immediately after collection. The other had its foam gland Semen quail emptied before mating see video, top. These results show that quail foam has a favourable effect on the survival of spermatozoa in vitro. National Semen quail for Biotechnology Information Adult movies share, U. The data were analyzed by analysis of variance [ 17 ], and means were compared by Duncan multiple range test [ 18 ]. Please review our Senen policy.

By Sara Reardon. Electric whisks, step aside. Male Japanese quail Coturnix japonica can use their sex organs to whip up a meringue-like foam. Japanese quail are round, speckled, friendly birds with distinctive white blazes around their eyes.

Females lay an egg a day, making them popular on urban farms — for their eggs as well as their meat. In the s, their rapid reproductive cycle led Russian cosmonauts to think quail might make a good extraterrestrial food source.

Japanese quail became the first birds in space in when eggs were flown to the Russian space station Mir and hatched there. Click here for video footage. Even in space male Japanese quail can easily make sperm and the strange white foam that accompanies it. When a male is ready to mate, he starts rapidly pulsing a sphincter muscle in the gland , which whips the liquid up into a frothy ball.

When he sees a female, he whips faster. As soon as he gets a chance, he mates with the female, secreting the stiff foam into her right after his semen. Female quail hold a clutch of several eggs in their bodies at any one time, and will often breed with multiple males.

In a series of experiments, they mated a female with two males, one after another. One male was allowed to mate normally, sending both his foam and his semen into the female. The other had its foam gland manually emptied before mating see video, top.

The mating was then repeated, this time with the foamless male going first. They repeated the experiment with 35 females. Later, the researchers performed paternity tests on the chicks. Males that were allowed to use their foam fathered significantly more chicks in each clutch than foamless males, suggesting it gives sperm a boost in the race to fertilise eggs.

Females can store sperm for over a week before letting it fertilise an egg, so the foam could be providing a nice environment for the sperm to sit in, keeping them alive for a long period of time. Or it may somehow help the sperm reach the target more effectively. Her team hopes to study this in future experiments. When the birds defecate, they leave a little blob of foam on top, which may help mark their territory.
