Leptin receptor expression and its change in association with the normalization of EGF profile after seminal plasma treatment in repeat breeder dairy cows [PDF]
The Journal of Reproduction and Development, 2022 Factors associated with high milk production levels have been linked to alterations in the endometrial epidermal growth factor (EGF) profile, a cause of reduced fertility in dairy cows.

Embryo transfer as an option to improve fertility in repeat breeder dairy cows [PDF]
Journal of Veterinary Research, 2021 Repeat breeding is a serious reproductive disorder in dairy cattle. The causes of repeat breeding are multifactorial and there are two main mechanisms: failure of fertilisation or early embryo death, mainly due to poor quality of oocytes and an ...

Effect of seminal plasma infusion into the vagina on the normalization of endometrial epidermal growth factor concentrations and fertility in repeat breeder dairy cows [PDF]
The Journal of Reproduction and Development, 2020 Epidermal growth factor (EGF) concentrations in the uterus show two peaks on days 2–4 and 13–14 during the estrous cycle in fertile cows. Loss of the two peaks has been linked to reduced fertility in repeat breeder cows.

Improvement of fertility in repeat breeder dairy cattle by embryo transfer following artificial insemination: possibility of interferon tau replenishment effect [PDF]
The Journal of Reproduction and Development, 2019 Repeat breeder cattle do not become pregnant until after three or more breeding attempts; this represents a critical reproductive disorder. Embryo transfer (ET) following artificial insemination (AI) in repeat breeder cattle reportedly improves pregnancy

Evaluation of the effect of sustained‐release progesterone injection on the expression of interferon‐related genes in repeat‐breeder dairy cows [PDF]
Veterinary Medicine and ScienceBackground Repeat‐breeder cows repeatedly fail to conceive after at least three attempts and return to oestrus at apparently normal intervals. Repeat‐breeder cows cause economic losses in dairy farms in different ways.
