Early embryonic death

Lethal recessive variation can cause prenatal death of homozygous offspring. Although usually present at low-frequency in populations, the impact on individual fitness can be substantial. Until recently, the presence of recessive embryonic lethal variation could only be measured indirectly through reduced fertility. In this study, we estimate the presence of genetic loci associated with both early and late termination of development during gestation in pigs from the wealth of genome data routinely generated by a commercial breeding company.

Cattle and buffalo are major livestock species for milk production contributing significantly to the economy of our country. High conception rates are crucial in a successful dairy farm to obtain a calf a year and sustained milk production. However, Repeat breeding continues to pose a major threat to economy of a successful farm. The main causes that convert high milk yielding dairy cattle and buffaloes into repeaters are mainly conception failure and early fetal death which may further have varying infectious and non-infectious etiologies, thereby severely disrupting the income.
