the semen is collected mainly for two reasons, firstly for breeding soundness evaluation (fertility) and secondly to be of use for artificial insemination (A.I, When being collected sperm preferably early in the morning time. tell me why please?
Dear Gaci,
in my opinion, Dr. Ahmed Ali response is true. Besides, the laboratory needs time for the sperm processing.

Is important to determine ever the species of which are you talking about. For bulls, that are in big AI Centres, semen is obtained at different time. Seems as "semen doses factories". But if you consider the hormone cycle in the male, morning would be the better time. In the case of boars, is useful the morning, before feeding them.
There is no specific time. Most laboratories require samples to be collected on-site as the semen needs to be examined within 60 minutes after ejaculation in order to maintain the quality of the specimen. Semen is collected in a private area by self-stimulation. Some men, for religious or other reasons, might want to collect semen during the act of intercourse, using a condom. If this is the case, the health care provider should provide the condom or sheath because lubricated condoms can affect test results.
Sperm are very temperature-sensitive. If collection is done at home, the sample should be kept at body temperature (98.6oF/37oC) by keeping it next to the body during transportation. It should not be left at room temperature for an extended period of time and should not be refrigerated. Sperm motility decreases after ejaculation; thus, timing and temperature are critical to obtaining accurate information. Poor sampling may require repeat testing.
dears,
Thank you for your interest, but I'm talking about the animal semen...Sorry if my question is not clear.
