Use of heterospermic inseminations in boar fertility
Sperm motility, morphology and three seminal plasma proteins were positively associated with heterospermic boar fertility.

Control points in the preparation of semen doses: temperature control and quality parameters (1/2)
The impact of semen used for post-cervical AI is 2-3 times bigger than that used to produce cervical insemination doses; therefore, preparation of the doses should follow an even stricter control program.
Practical tips to induce heat in gilts and sows
Boar exposure time, duration and frequency, proper boar: gilt or sow ratio, exposure methods, hormones, …
The dependence of the growth rate and meat content of young boars on semen parameters and conception rate
The objective of the research was to conduct semen parameter and conception rate analyses on the basis of growth rate and meat content.
Never miss a heat: Build a better boar bachelor pad
Automated heat detection identifies open sows safely and accurately.
Magapor establishes in the USA and expands its factory in Spain
This new stage in the North American market reinforces the bet and work done in the last 10 years in the United States.
Optimization of post-cervical artificial insemination in gilts: Effect of cervical relaxation procedures and catheter type
Post-cervical (pC) artificial insemination (AI) has been successfully developed for application in multiparous sows, although it has proved problematic in gilts. This study analyzes the use of pC-AI in gilts by two experiments.
NPD: An invisible component for herd productivity
We recommend that producers pay more attention to gilts and sows that are at risk of increasing NPD. Situations of increased risk are described.
Strategic value of boar studs in production systems
Production of a minimum number of doses to maintain profitability and the increase in post-cervical insemination leads to an increase of the doses produced per boar and, therefore, their share of responsibility in the production process.
Use of altrenogest on pig farm
The shorter and lower dose regime saves money but there is an increased risk of follicular cyst development, which may occur at doses below 13mg/day.
Economic impact of post-cervical insemination on a farm
Introduction of post-cervical insemination has a very significant economic impact on the whole of the pork industry, and is a challenge of parallel magnitude to that raised by the transition from natural service to artificial insemination.
Control of oestrus in problem gilts and sows
Meeting batch breeding targets requires availability of enough service-ready weaned sows and gilts.
Optimization of post-cervical insemination in pigs: critical points
This article lists the critical points that must be considered for a successful post-cervical insemination in sows.
Improving the sows perception of the boar
The idea is to modify the doors of the pen where sows are housed in groups to increase the contact with the boar.
Current state of post-cervical insemination in multiparous, primiparous and nulliparous sows
It is necessary to find alternatives to definitely implement this technique in primiparous sows and start its use in gilts.
Morphological study of boar sperm during their passage through the female genital tract
Almost all the sperm that colonize the uterotubal junction had a normal morphology, with part of the abnormal sperm having been discarded in the backflow and part selected/modified on their way to the oviduct.
