Calf mortality as a welfare indicator on British cattle farms

The objective of this study was to test calf mortality as an indicator of on-farm welfare and its use for welfare targeted surveillance. Calf mortality data were retrieved for three UK counties to estimate calf mortality rates at holding and county level. A selection criterion based on upper quartiles of calf mortality for the county of concern was defined. Its predictive ability was tested in a field study. The death risk of calves less than 6 months of age in 2002 was 1.76% in Inverness, 5.83% in Cheshire and 4.8% in Norfolk. Fifty-two welfare inspections matched by parish were conducted between October 2004 and January 2005. The positive predictive value was 26.92% and the negative predictive value was 65.38%. The addition of herd type, county and membership to an assurance scheme improved the predictive value. This study shows that calf mortality can be the starting point to design targeted welfare inspections in countries with centralized animal data recording systems.

Origins, phylogenetic relationships and host-parasite interactions of Troglotrematoidea since the cretaceous

In the current study, we raise the issue concerning origins and historical relationships of the trematodes from the families Troglotrematidae and Paragonimidae using phylogenetic analysis and molecular-clock method for estimating evolutionary rates. For the first time we provided 28S rRNA gene fragment (1764 bp) for the type species Troglotrema acutum - zoonotic trematodes that cause cranial lesions (troglotremiasis) in mustelid and canid mammals of the Central Europe, Iberian Peninsula, and North-West Caucasus. Molecular genetic analysis revealed that T. acutum belongs to the monophyletic family Troglotrematidae sister with the family Paragonimidae. The family Troglotrematidae includes five genera: Nanophyetus, Troglotrema, Skrjabinophyetus, Nephrotrema, and Macroorchis; and the family Paragonimidae is monotypic including the only genus Paragonimus. We recover the superfamily Troglotrematoidea for these two families. Divergence of the common ancestor of the superfamily Troglotrematoidea (common troglotrematoid ancestor) likely occurred during the Cretaceous period of the Mesozoic Era and potentially originated in the Asiatic region. The lineage of the family Troglotrematidae is much closer to the common troglotrematoid ancestor than the species of the family Paragonimidae. The radiation time of the common troglotrematoid ancestor (126 Ma, the Early Cretaceous), and formation of the families Troglotrematidae and Paragonimidae (96 Ma and 73 Ma respectively, the Late Cretaceous) corresponds to the time of settling in East Asia by many species of mammaliaforms (about 130-70 Ma
