Answer :
Final answer:
The correct option is b) 'transcervical insemination in the ewe is the easiest route', which is not true due to the complex anatomy of sheep and goats. The correct approach typically involves depositing semen in the vagina, cervix, or uterus, with timing after estrus detection and a higher conception rate when semen is deposited further into the reproductive tract.
Explanation:
The statement about artificial insemination in sheep and goats that is NOT true is that 'transcervical insemination in the ewe is the easiest route'. In fact, transcervical insemination can be challenging due to the anatomy of sheep and goats, which makes it difficult to navigate the cervix. Moreover, semen may indeed be deposited in the vagina, cervix, or uterus. Insemination is most commonly performed around 12 hours after estrus detection, aligning with the optimal timing for fertilization. Additionally, it is generally accepted that the further semen is deposited into the reproductive tract, up to the uterus, the higher the conception rate tends to be.
The procedure of artificial insemination provides several benefits in animal husbandry, including the ability to multiply male genetic contributions and overcome logistical constraints. Enhanced by progress in the viability of cryopreserved semen, artificial insemination techniques help manage the reproductive cycles and insemination timing more effectively.
