Ky Pohler, Ph.D.
Dr. Ky Pohler is an Assistant Professor and a member of the graduate faculty in the Department of Animal Science. He grew up in Shiner, TX and received a B.S. in Animal Science from Texas A&M University in 2009. He then received a M.S. and Ph.D. from the University of Missouri. Prior to returning to Texas A&M, Dr. Pohler was on faculty at the University of Tennessee in the Department of Animal Science.
Dr. Pohler’s research
interest focus on understanding the physiological and molecular mechanisms
that control reproductive efficiency in cattle. More specifically his lab
is interested in the mechanisms that lead to embryonic and fetal mortality
in cattle and development of management strategies to overcome these
losses. Embryonic mortality can be classified into early (< d 28 of
gestation) or late (> d 28 of gestation) depending on the exact timing
at which it occurs during gestation. Reports of high fertilization rates
after a single insemination (~90%), followed by pregnancy rates of 60 to
70% on d 28 in cows indicate that early embryonic mortality may be 20 to
30% in beef cows. Documented causes of early embryonic mortality range
from genetic abnormalities to uterine-embryo asynchrony to failure of
maternal recognition of pregnancy and this has been an area of intense
investigation. Late embryonic mortality (> d 28 of gestation) has been
reported in both beef/dairy cattle and may vary from 3.2 to 42.7%.
Currently, there is very little known about the causes of late embryonic
mortality. However, the economic consequences of each unit of late
embryonic mortality are greater than that of early mortality. Along with
the increased economic consequences, late embryonic mortality is becoming
more evident in both the beef and dairy industries based on the shift to
early pregnancy diagnosis (~d28-35 of gestation).
