As such, artificial A study was conducted to compare conception rates in 71 Tuli and 86 Afrikander beef cattle bred using either artificial insemination (AI) or the bull. The Abstract This research was motivated by the exponential increase in embryo transfer (ET) use with >5 times as many ET calves born in the U. Understanding Artificial insemination was the first reproductive technology applied to cattle, initially in Russia and Denmark during the early 1900s (Ivanoff, 1922; Perry, 1945). The research method used was a field experiment with three The conception rate (CR) represents the proportion of cows that became pregnant after the first insemination (Souames and Berrama, 2020). Due to this low The highest conception rates among cows intensively observed may have been the result of a more appropriate time of artificial insemination relative Results will be provided in future publications. Service Timed artificial insemination (TAI) is a technology widely used in cattle production based on the recent understanding of the main factors controlling ovarian follicular growth (Bó et al. Due to its many advantages, artificial insemination has inevitably Comprehensive comparison of natural vs artificial insemination in cattle. , 2002); however it faced a major challenge of low The success of artificial insemination followed by pregnancy depends on the reproductive health of the cow, the accuracy of estrus detection, The objective of this study was to evaluate the factors that may affect conception rates (CR) following artificial insemination (AI) or embryo transfer (ET) in lactating Holstein cows. Estrus synchronization protocols have virtually eliminated the need for estrus (heat) Proper Artificial Insemination Technique in Cattle for Optimum Conception and Pregnancy Artificial insemination (AI) has revolutionized the Rate of conception was affected by estrous behavior at 12 h, site of semen placement in the reproductive tract, sire, and environmental temperature the day after insemination. Increasingly, Artificial insemination is an effective management strategy to improve the reproductive performance and genetics of a herd (Foote, 2002). It is expressed as a percentage and calculated by dividing the number of pregnant cows by the total number of inseminations in the herd This study analyzed risk factors influencing the conception rate at the first artificial insemination (CR1) in dairy cows reared in the plain of Mitidja, which is considered a major dairy region in North Algeria. Service number, time of day at which insemination occurred, inseminator, and timing of insemination in relation to the onset of estrus had no effect on fertility. This parameter was used to assess the success of Key factors influencing conception rates during artificial insemination (AI) in cows are explored, focusing on enhancing AI success rates In conclusion, data collected suggests acceptable pregnancy rates may be achieved within a fixed-time artificial insemination protocol using sexed semen regardless of age, weight, Here, it is pertinent to note that the current average conception rate in dairy cattle when inseminated with 20 million spermatozoa is around 35% in India, which may further go down when 2 million This study analyzed risk factors influencing the conception rate at the first artificial insemination (CR1) in dairy cows reared in the plain of Mitidja, which is considered a major dairy region in North Algeria.
