Abstract

Artificial insemination has been a landmark procedure in improving animal agriculture over the past 150 years. The utility of artificial insemination has facilitated a rapid improvement in animal genetics across agricultural species, leading to improvements of growth, health and productivity in...

Abstract

The present study was conducted to analyse the factors influencing the success of artificial insemination (AI) in pigs using extended fresh semen in rural smallholder pig farms. One hundred female pigs from Rulindo and Gicumbi districts in Northern Region of Rwanda were artificially inseminated...

AbstractFull Text

The objective of this study was to evaluate the reproductive performance of gilts subjected to post-cervical artificial insemination (PCAI) compared to traditional artificial insemination (TAI). We also evaluated the degree of difficulty in bypassing the cervix, time required to perform the ...

Abstract

Artificial insemination with frozen-thawed semen in pigs is not a routine technique; its use is restricted to specific cases, such as preservation of valuable genetic material (germplasm banks), safety strategies in case of natural disasters, long-distance transport of sperm, and in combination...

Abstract

This study was conducted to assess the factors that affect pig litter size, proportion of live pigs at birth, number of inseminations per conception, and efficiency of artificial insemination. The main factors assessed were sow breed (n=2), sire breed (n=3), sow parity (n=7) and insemination method ...

Abstract

Seminal plasma has conventionally been viewed as a transport and survival medium for mammalian sperm; however, its role now extends beyond this process to actively targeting female tissues. Studies in rodents, swine, and humans demonstrate that seminal plasma induces molecular and cellular changes...

Abstract

180 White pigs of Dan lines with more than 2 parities were divided into 2 groups and inseminated with 10 cm deep intra-uterine insemination and artificial insemination at doses of 30, 15×108/80 mL and 15×108/40 mL, respectively, to investigate the effects on reproductive performance. The conception ...

Abstract

Fixed-time post-cervical artificial insemination (FTAI) drastically reduces labour requirements and increases the use of boars with higher genetic merit. This study evaluated the efficiency of eCG administration combined with/without the GnRH agonist buserelin for the induction and synchronization...

Abstract

The preservation of chilled boar semen for artificial insemination is the most performed worldwide. For this, the sperm are extended in medium that provides substrates to nourish and protect these cells. However, the storage temperature range of chilled semen is not able to completely stop the...

Abstract

Boar exposure is used to stimulate follicle development and estrus in sows after weaning and also to improve semen uptake and sperm transport with insemination. However, the need and value of boar exposure is uncertain when ovulation induction is used. These studies were designed to determine the...
