The objective of this study was to quantify the efficacy a second intrauterine cephapirin treatment administered 14 d after initial one on subsequent reproductive performance postpartum dairy cows affected by purulent vaginal discharge (PVD) or endometritis (ENDO). In total, 4,140 Holstein from 30 commercial herds were enrolled in randomized clinical trial. At 36 (±7) milk, examined using Metri...

The aim of the study was to compare the effect of two acute puerperal metritis (APM) treatment protocols on uterine condition during the late puerperal period (5th to 7th week). Late gestation healthy cows (n = 21) were divided randomly in three equal groups. Parturitions were induced. Treatments of APM were started on the third day postpartum (PP). Group A was treated with an oxytocin analogue...

We analyze dynastic repeated games. These are repeated games in which the stage game is played by successive generations of finitely-lived players with dynastic preferences. Each individual has preferences that replicate those of the infinitelylived players of a standard discounted infinitely-repeated game. Individuals live one period and do not observe the history of play that takes place befo...

We analyze government interventions to recapitalize a banking sector that restricts lending to firms because of debt overhang. We find that the efficient recapitalization program injects capital against preferred stock plus warrants and conditions implementation on sufficient bank participation. Preferred stock plus warrants reduces opportunistic participation by banks that do not require recap...

The duration of a supply relationship depends on two types of costs: (i) the transaction cost of switching suppliers and (ii) the cost of being matched to an inefficient supplier when the relationship lasts too long. I develop a model of optimal contract duration that captures this tradeoff, and I provide conditions that identify the underlying cost structure. Latent transaction costs are ident...

Three laboratories participated with their laboratory-specific microbiologic growth assays (MA) in the NHANES 2007-2008 to assess whether the distributions of serum (n = 2645) and RBC folate (n = 2613) for the same one-third sample of participants were comparable among laboratories. Laboratory (L) 2 produced the highest and L1 the lowest serum and RBC folate geometric means (nmol/L) in the NHAN...
