Abstract
A Bargur cattle is an endangered cattle breed present in Anthiyur Taluk of Erode district. It is known
for its suitability in the hilly agricultural operations. Population of these cattle breed downturn drastically in
the past decades due to mechanisation of agriculture and indiscriminate breeding of these animals. Ex situ
Conservation of the Bargur cattle through the preservationof male gametes was proposed to increase the
population size of these breed. For this operation twenty numbers of Bargur calves were procured from the
Bargur cattle breeding tract based on the phenotypes and dams yield. All the selected calves were screened
for Karyological screening to rule out the chromosomal abnormality. Genetically transmitted diseases and
infectious diseases were screened as per the approved protocol recommended by the Central Monitoring Unit,
Government of India. The average age of bull calves at the time of selection was about 1 to 1.5 years, these
animals reared under the organised farm till the semen donation was started. The bulls were shifted fromBargur cattle research station to Semen Bank, VC & RI, Namakkal for semen collection and preservation.
The average body weight of breeding bulls at the time of semen collection was 183.133 2.14 kgs.The normal
seminal parameters such as volume (ml), colour, consistency, mass activity (scale 0-5) and sperm concentration
(million/ml) was recorded.The mean volume of the semen samples were 3.708 0.125 ml.The colour of all
the samples was creamy white. The mass activity of Bargur semen was 3.93 0.118 and the concentration
1221.01± 56.09.This is the first time the semen was collected from the endangered Bargur bulls and values
may be used as referral values for Bargur breed. The semen was diluted according to their concentration and
proceeds for further processing.
