Working in semen station. Facing problem in the semen processing of some bulls. HF pure bred is not performing well after processing/freezing. Freezing protocol is same as for other bulls and as per recommendation of MSP. Some of bulls donating semen with more dead sperms. One bull semen is exhibiting much more number of mid piece deflection abnormality. Bulls are reared in hilly area where temperature is around 13-24 degree centigrade.
Try changing the déluant or change feeding bulls especially Omega 3 type. Flax seeds crushed give good results. Good luck.
Try giving pre-collection stimulation to the bull, e.g. short exposure to new female cows and even change the location might help.
Try to use low concentration of royal jelly to the feeding ,good luck
Hi. I experienced similar problem and the reason of pure sperm quality was the quality of water. Of course you need to feed the bulls properly. I would not expose the bull to female, try it with males instead. Good luck
