Journal ArticleDOI
Defining postpartum uterine disease in cattle.
TL;DR: Suggestions for common postpartum uterine diseases are suggested, which can be readily adopted by researchers and veterinarians.
Journal ArticleDOI
Steroidal regulation of uterine resistance to bacterial infection in livestock
TL;DR: It is hypothesized that eicosanoids can override the negative effects of progesterone and that the up-regulatory effects of exogenous prostaglandin F2 alpha allow the uterus to resolve an infection, regardless of progestersone concentrations.
Journal ArticleDOI
Oestrus detection in cattle: recent developments
TL;DR: A review of recent studies on improvement of oestrus detection aids and development of methods for determining the proper insemination time, without the need to detect the behavioural manifestation of Oestrus is presented in this paper.
Journal ArticleDOI
Shedding of ovine herpesvirus 2 in sheep nasal secretions: the predominant mode for transmission.
TL;DR: The data herein show that nasal shedding is the major mode of OvHV-2 transmission among domestic sheep and that adolescents represent the highest risk group for transmission.
Journal ArticleDOI
Spontaneous uterine infections are associated with elevated prostaglandin F2α metabolite concentrations in postpartum dairy cows
TL;DR: Data indicate that plasma PGFM concentrations are greater in postpartum cows with spontaneous uterine infections then in herdmates free of infection.
