UB Faculty of Animal Science Lecturers Together with PT. Nestle Indonesia Provides Training on Frozen Semen Quality Test

Lecturers of the Faculty of Animal Science Universitas Brawijaya (Fapet UB) through the Independent Campus Competition Program (PKKM) animal husbandry study program held training on skills to test the quality of frozen spermatozoa (semen), Wednesday (7/9/2022). Activities in collaboration with PT. Nestle Indonesia is intended for Cooperatives inseminators and suppliers of PT. Nestle.

Located in the senate meeting room, 6th floor of Gd.V, the event was opened by the Dean, Prof. Suyadi. In his speech he said Artificial Insemination (AI) is the main key to increase population and genetic quality in livestock. 

“The spearhead of the success of this IB method also depends on the expertise and skills of the inseminators who attended today’s training.” said Suyadi

So that it is necessary to upgrade the insight and knowledge of the inseminator from time to time to increase the ability. In order to encourage the success of pregnancy in livestock.

Furthermore, the professor of livestock reproduction expert, Prof. Trinil Susilawati provides an explanation of the theory regarding the factors that cause reproductive failure. According to her, reproductive failure is caused by the wrong timing of estrus in female cattle, feeding of low quality, improper selection of seeds, and damage to semen.

“Semen damage can be caused by the cryopreservation process before AI. Namely, temperature reduction, cell dehydration, freezing, storage, and then thawing.” said Trinil

“Spermatozoa damage can be in the form of damage to the plasma membrane, acrosomal membrane, and biochemical damage in cells. The cause can occur during the freezing process, due to cold stress and the formation of ice crystals.” clarity

Assessment of frozen semen quality can be done microscopically through motility, concentration, viability (percentage of life) tests, and morphological tests (spermatozoa abnormalities). These activities are presented to participants directly in the livestock reproduction laboratory. So that they can witness and practice cement quality testing techniques.  

“We hope that through this activity, the inseminators can test the quality of frozen semen. So that in the future it will minimize the failure of the IB method caused by the lack of knowledge of the inseminator officers.” concluded Trinil (dta)
