The 49th annual Incubation and Fertility Research Group meeting was held at the Limak Limra Hotel & Resort in Antalya, Türkiye, on October 3rd and 4th.
This is one of the most important meetings related to avian reproduction and incubation worldwide.
The group that organizes it is the Working Group Six (WG6) and is part of the European Federation of the World’s Poultry Science Association (WPSA).
This year, 87 participants from 26 countries attended this meeting.
Thirty presentations covered topics amongst others about fertility, egg production, egg treatments during storage, incubation conditions, and data analysis. We recommend you to attend next year in Berlin.
FERTILITY
Rooster Fertility
Dr. Anais Vitorino Carvalho from INRAE presented a new strategy to diagnose sperm fertility based on proteomic methods using Intact Cell MALDI-TOF Mass Spectrometry (ICM-MS) to an isolated cell population to describe peptides and proteins that can be better correlated to male fertility.
Dr. Carvalho also presented a new solution to remove glycerol from post-thawed chicken semen to help with the success of cryopreservation.
This new method can be processed at room temperature to restore sperm fertility, reducing 44% of the time required with the classical glycerol removal procedure.
Fertility Biomarker
Dr. Ophélie Bernard from INRAE discussed the value of chemerin protein as a biomarker to improve reproduction rates.
Chemerin in albumen is positively correlated (r = 0.26) with fertility rates for layer hens and negatively correlated with laying (r = -0.51), fertility (r = – 0.31), and hatchability (r = -0.29) rates for broiler hens.
Expression of this protein is higher in layer hens than in broiler hens. Chemerin was correlated with some reproductive parameters and with embryo development.
Pesticides on Semen Parameters
Pesticides used as fungicides (Ebuconazole), insecticides (Imidacloprid), and herbicides (glyphosate) can contaminate corn and soybeans.
The toxicity of these products is a concern in the entire animal industry.
Skarlet Napierkowska from Wroclaw University evaluated the effects of these pesticides and their mixtures below the minimum risk level for feed grains on Greenlegged Partridge rooster’s semen parameters and hormone levels during exposure and after a four-week break.
Exposure to all pesticides ca...
