Appropriate Insemination Time The main factor of determining

Appropriate Insemination Time • The main factor of determining appropriate time for insemination is detection of ovulation time. • Other than that; fertile lifespan of ovum and spermatozoon, semen storing contidions and quality are also criteria that should be kept in mind.

Appropriate Insemination Time • Cow Estrus duration 12 -18 hours Ovulation time 10 -12 hours after estrus ending Sperm fertile viability 24 -36 hours Ovum fertile viability 20 -24 hours Appropriate insemination time Last half or third of estrus Insemination method Recto-Vaginal method Place of semen deposition Corpus Uteri

Appropriate Insemination Time ‘Morning/Afternoon’ Insemination Method If estrus is detected in the morning, they are inseminated in the afternoon. If estrus is detected in the afternoon, they are inseminated the following morning.

Appropriate Insemination Time ‘Once in the morning’ or ‘ 8 -11 One insemination’ Method In this method, regardless of when the estrus is detected, the insemination is done the following morning from 8. 00 to 11. 00 a. m.
