Spanish Journal of Agricultural Research, 2014 A deterministic simulation was conducted to assess the effects of sexed semen utilization strategies on age at first calving (AFC). Four different strategies were implemented on dairy heifers: continuous use of conventional semen only (CC), continuous ...

Productive life in buffalo cows and effect of some factors on it
Italian Journal of Animal Science, 2010 Subject of investigation were 3989 buffaloes from the Bulgarian Murrah breed during the period 1976 – 2003. The productive life (PL) is determined as the period between date of first calving to the date of last milking, before culling.

Advanced Science, EarlyView.Porcine deltacoronavirus (PDCoV) infection induces severe intestinal inflammation and acute diarrhea in piglets, yet the molecular mechanism remains incompletely understood. The M protein activates NLRP3 inflammasome through dual mechanisms: direct binding to the NLRP3 LRR domain and disruption of TRIM31‐mediated K48‐linked ubiquitination.

Accounting for animal health in efficiency analysis: An application to Swedish dairy farms
American Journal of Agricultural Economics, EarlyView.Abstract Poor animal health is a central concern in modern livestock production. Despite the necessity to incorporate animal health in efficiency analysis, the theoretical and empirical developments are limited on this subject. This article appropriately characterizes the axiomatic properties of animal health within a production framework.
