UNAIR NEWS – Faculty of Veterinary Medicine (FKH) UNAIR has been successfully developing frozen semen. Since 2001 the academicians of Faculty of Veterinary Medicine (FKH) Universitas Airlangga has started developing frozen semen from the male cows. But, frozen semen production, certified and standardized, was started two years ago, in 2014.

The expert and lecturer of artificial insemination (IB) FKH UNAIR Dr. Trilas Sardjito, drh., M.Si., explained that the project of frozen semen development was started from its willingness to fulfill request of Animal Husbandry Agency through the Governor of East Java. The lecturer of FKH was requested to supply the frozen semen stock for cows in East Java.

“At that time we were asked to produce three thousand to eight thousand and they were from male cows ex-Tapos,” said Trilas.

Even though at that time there was no laboratory equipments, FKH lecturer said yes. The competent human resources was the only main factor.

During its early development of frozen semen, FKH UNAIR used male cows which the origin has not been identified. Therefore the team used the cows for trials on the production and effectiveness of the semen. Until finally, the team had an opportunity to use the male cows ex-Tapos, the cows then identified and certified by the authority.

“Certified cows showed that they deserve to be male as they have excellent body and with postures, length and all meet the retirement, including their weight at birth and its weight gained,” said Trilas.

Current progress

In 2012, through a collaboration scheme, FKH team led by Trilas bought five various breeds from Australia. They were 2 Simmentals, 2 Limousines and 1 milking cow. All of them were placed in a teaching farm in Gresik.

These cows were used for frozen semen production. In 2013, they were trained to mate. A year after, in 2014, the male cows then used for the frozen semen production. One ejaculation of cow can produce 500 packages of frozen semen but the average is ranged from 200 to 300 packages in one ejaculation.

But the production depends on some factors. One of them is the season. “In an uncertain season, it is difficult to get a lot of semen,” said Trilas.

From some trials of artificial insemination in some regions, the frozen semen produced by UNAIR showed promising result. In 2009, from the program implementation in Kediri, from 100 packages of frozen semen, there were 77 pregnant female cows in the first mating and 11 more in the second mating.

The regions supplied by frozen semen of FKH UNAIR were Banyuwangi, Jember, Nganjuk, Lamongan, Bojonegoro, and Sidoarjo.

The frozen semen innovation by FKH UNAIR is expected to support the government program, SIWAB (cattle obligatory pregnancy). With this excellent results showed by FKH UNAIR, Indonesian Minister of Agriculture has requested UNAIR to produce at least 20,000 frozen semen. (*)
