Allen D. Leman Swine Conference 2024 Summary: Reproduction and production
Antonio Palomo summarizes the swine production and reproduction presentations from the latest Allen D. Leman Swine Conference 2024.
Evaluation of different thawing protocols on Iberian boar sperm preserved for 10 years at different liquid nitrogen levels
Thawing at 70 °C for 8 seconds maximizes post-thaw sperm quality, especially in those samples stored constantly submerged in liquid nitrogen.

In this third installment, Antonio Palomo summarizes the papers presented on reproduction, nutrition, precision livestock farming, and other aspects of swine production.
Low-density lipoproteins, resveratrol and quercetin as alternative additives to improve boar semen cooling
Low-density lipoproteins can improve the motility and kinetics of boar semen during cooling while it could modulate the sperm's mitochondrial activity.

Antonio Palomo summarizes the presentations from the latest AASV, ranging from the future of the veterinary profession to the eradication of diseases, hog prices, and experiences in improving pig survival.
Myo-inositol improves the viability of boar sperm during liquid storage
The addition of myo-inositol to semen extender improved the boar semen quality by decreasing the effects of oxidative stress during liquid preservation.
Practical experience: Ability to detect PRRS infection in boars by sample type
Are we using the best samples and techniques to monitor PRRS absence in boar studs?
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.
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.
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.
Suitability of semen stress tests for predicting fertilizing capacity of boar ejaculates
Cold- and heat-resistance were dependent factors and sperm motility but neither semen stress test can be used as a sole test for predicting the fertilizing capacity of boar ejaculates.
