Vaginal and vestibular electrical resistance as an alternative marker for optimum timing of artificial insemination
Change in electrical resistance in the vagina has the potential to accurately predict ovulation timing, but more work is required.
Tip: Book to record weekly matings
In this logbook, each page corresponds to a week of the year in which all the matings during the week are recorded.
Analysis of artificial insemination center management factors that contribute to sperm parameters and boar longevity
The results reveal better sperm quality for untreated boars than for PGF2α-treated boars, which might indicate that the underlying fertility of boars necessitating treatment is inferior compared to boars that can be collected without further treatment.
Differences of semen microbiota among breeding boars with different reproductive ages
The semen of older boars contained a higher abundance of harmful bacteria, which contributes to the observed reduction in semen anti-oxidant capacity and overall semen quality in this group.
Reproductive performance of gilts and weaned sows grouped at different days after insemination
Group housing gestating sows 2 days after breeding compromised litter size; however, mixing gilts on days 1 to 4 after breeding did not impair reproductive performance.
Update on the methods for semen quality evaluation in swine from farm to the lab
This work aims to summarise the methods utilised in farms and research laboratories to evaluate sperm quality in pigs.
Tip: Waist bag for farrowing assistance
Use a waist bag to always have the supplies you need for farrowing assistance at hand.
Hypor dam lines: Key management aspects
In this article, we focus on the key aspects of management to optimize performance from this genetic line of sows. We talked with Carlos Martins.
Intrauterine immunization as an industry-friendly route of vaccination in pigs
What if this novel vaccination route could easily be incorporated into current animal husbandry practices and protect animals against disease?
New genes available from Breeders of Denmark A/S - Danish Genetics Partner with Semen Cardona in Mexico
Our genetics will take Mexican farmers to new levels of production and better economical benefits.
Dynamic group gestation with weight monitoring
Continuous monitoring of sow weight has significantly improved feed use efficiency and sow longevity.
"Why Pig Artificial Insemination" webinar
The recording of the webinar is available for viewing.
Polyamines protect boar sperm from oxidative stress in vitro
Spermine and spermidine alleviate oxidative stress via the antioxidant capacity, thereby improving the efficacy of boar semen preservation.
Intrauterine immunizations trigger antigen-specific mucosal and systemic immunity in pigs and passive protection in suckling piglets
The study assessed whether vaccines administered to the uterus at breeding can lead to sufficient colostral antibodies to protect suckling piglets against PEDV.
What fractions of the ejaculate should I include when preparing artificial insemination doses?
Currently, only the sperm-rich fraction is used. This article analyzes the possible use of the other fractions.
