Dr.Dan Ryan   PhD

Dr.Dan Ryan  

Dr. Dan Ryan is a leading international specialist in reproduction in beef and dairy cattle. He has a wealth of experience, backed up by impeccable credentials and longstanding collaborations with leading universities.

 

In Saudi Arabia, Dr. Ryan developed evaporative cooling systems in conjunction with Arizona State University. This resulted in a 1.8 litre increase in milk production per cow per day among cows with a 9000 litre rolling herd average in a 305 day lactation. Pregnancy rates also increased from 15% to 35% to first insemination.

In Baton Rouge, Louisiana State University, Dr. Ryan developed a system for IVF of pregnant females which increased the opportunity to harvest genetics from superior females during their life-time. Dr. Ryan continued his post doctorate at Texas A&M University where he evaluated the impact of feeding high fat diets on fertility in malnourished cows. The impact of this technology resulted in improved reproductive performance in cows which were compromised by insufficient dry matter intakes in an arid climate.

Dr. Ryan returned to Ireland in 1992 to set up a programme in Reproductive Physiology at the National Dairy Research Centre in Moorepark, Fermoy, Co. Cork. He evaluated various hormonal treatments to enhance pregnancy rates in dairy cows and systems to increase submission rates and to decrease the calving to pregnancy interval.

In 1995, Dr. Ryan set up his own fertility management consultancy firm ‘Reprodoc Ltd’ which has grown into an international service for clients in beef and dairy production. The objective of this service is to offer preventative health management programmes.  These programmes identify stressors in the environment which impact negatively on fertility.

Dr.Dan Ryan has collaborated with a number of research centres such as Teagasc,The National Dairy Research Centre in Moorepark, Fermoy, Co.Cork, Munster A.I.Station, Mallow, Co.Cork, The Department of Veterinary Medicine in U.C.D., and The Biomedical Centre at The University of Ulster in Coleraine, Co. Derry.
