What is a good AI conception rate?
During the past 50 years that AI has been practiced in the U.S. the fertility of virgin heifers has remained relatively constant at approximately 65% first service conception; whereas, the first service conception rate for lactating cows has decreased approximately 33% from 60 to 40%.
What is fixed time artificial insemination?
FTAI allows artificial insemination (AI) of your herd without the need for heat detection. To enable FTAI, a series of treatments are given to the females according to a protocol that will synchronise the time of their ovulation.
Is artificial insemination more efficient?
The multiple delivery rate was 13.3% in the IUI/COH group compared to 10.1% in the IVF group (P = 0.55). One set of triplets and one set of quadruplets followed IUI/COH treatment. Conclusions: One IVF treatment programme was more effective, but costlier than an intended course of two cycles of IUI/COH.
What is a good AI rate in cattle?
The success rates of AI programs vary widely dependent on a number of contributing factors. As a basic guide we would suggest that 50-60% pregnant would be satisfactory, 60-70% would be a good result and above 70% would be an excellent result.
Is ICI or IUI better for home insemination?
An older 1988 study showed no statistical difference in pregnancy rates between 53 infertile women trying artificial insemination at home versus a clinic. A 2001 study of 62 women over 189 cycles found that IUI had higher monthly success rates than ICI (15 percent versus 9 percent).
Which animals have the highest conception rate using AI?
The average conception rate of AI was 69.5% in first-born cows, 61.8% in second-born cows, and 48.2% in third-born cows when conventional frozen semen was used, whereas it was 64.2%, 58.8%, and 46.2%, respectively, when sexed frozen semen was used.
When should a bull be placed after AI?
To distinguish between AI and bull bred pregnancies at pregnancy diagnosis, wait approximately 10 days to turn in clean up bulls after AI. Pregnancy check by 75 days after AI via ultrasound or 80–90 days after AI via rectal palpation to distinguish AI from bull bred pregnancies.
Which specie use the highest percentage of artificial insemination?
Despite cattle making up the largest portion of the AI industry in value [7], the U.S. swine industry is close behind and actually conducts the highest percentage of AI out of any livestock species, with more than 95% of all pig litters in the U.S. being sired through AI [18].
What is the success rate of ICI?
ICI can be conducted at home or a medical center. The success rate ranges from about 5% to 30% per cycle – and it may be more efficient if the woman places a sponge cap over the cervix for several hours afterwards to hold semen in place. Washing the sperm may also increase effectiveness.
Which sperm is better for at home insemination?
The recommended amount of sperm you should purchase for your home insemination is 2 x ICI or IUI MOT10 straws. ICI-ready sperm is typically used for home insemination, and IUI-ready sperm is usually used for clinic insemination, but both can absolutely be used in a home insemination.
How do you heat a cow for artificial intelligence?
To get the needed overlap for conception, the best rule of thumb for AI breeding is to inseminate 12 hours after first observing the cow in standing heat. Furthermore, if/when cows are still standing after the first AI breeding, follow up again with another AI service 12 hours later.
What is the success rate of AI in sheep?
The insemination is carried out on synchronized estrus and the pregnancy rate is around 60% (Naim et al., 2009) -70% (Prieto et al., 2011), using sperm concentrations ranging between 60 and 100 total million sperm per ewe.
How can I increase my chances with ICI?
To increase the chances of pregnancy, the insemination procedure is usually performed two times during each cycle. Sperm washing may also increase the chances of pregnancy with ICI.
Which is more successful IUI or ICI?
IUI may result in higher clinical pregnancy rates than ICI (OR 2.83, 95% CI 1.38 to 5.78; 2 RCTs, 131 women; I² = 0%; very low-quality evidence). IUI may be associated with higher multiple pregnancy rates than ICI (OR 2.77, 95% CI 1.00 to 7.69; 2 RCTs, 131 women; I² = 0%; very low-quality evidence).
Do you inseminate on ovulation day?
Because you can’t predict exactly when ovulation is taking place, it’s a good idea to inseminate two days in a row, twelve-hours or twenty-four hours apart. This way you increase your chance of having live sperm waiting in the fallopian tube as the egg begins traveling down the tube after ovulation.
Fixed Time Artificial Insemination (FTAI) is popular, cost effective and relatively simple reproductive technology, ideal for increasing the overall genetic merit of your herd and, importantly, adding significantly increased profitability to your beef operation.
What is the high conception rate program?
Our High Conception Rate (HCR) program, paired with Fixed Time Artificial Insemination (FTAI) will deliver big genetic gain in shorter mating and calving periods, improving efficiency and profitability for producers. An article written especially for ABS by Dr Cliff Lamb, following his 12 day seminar tour to Australia in April 2016.
Is the five-day IVF protocol more labor intensive?
Unfortunately, the five-day protocol is more labor intensive, which may offset the observed fertility advantages.
