Second, by assembling a series of variables quantifying the distribution of different pig types in the country and anthropogenic factors, we also aimed to carry out a first investigation of the risk factors most strongly associated with all PRRS occurrences, possibly including HP-PRRS in Thailand.
In Model 1 these variables were: number of pigs, type of production and type of feed.
Although both genotypes of PRRSV can raise similar clinical signs in pigs, type 2 PRRSV has been demonstrated to have significantly greater virulence to induce respiratory disorder than type 1 PRRSV [ 10, 11].
The cold-cathode Penning ion gage (PIG -type ion source is designed for the internal ion source of the comPIG -typeotron.
Dr Roff stated that "it puts the lie to the British government's claim that they never used humans for guinea pig-type experiments in nuclear weapons trials in Australia".
We simulated human-type and pig-type pedigrees with a range of quantitative trait loci (QTL) effects (0.5 3% of phenotypic variance) and heritabilities (0.3−0.8).
Using a simple example with three pedigrees, [ 41] demonstrated that the type 1 error rate of the regression method increased with heritability and family size (from unrelated small nuclear families to a mixture of half- and full-sib families in pig-type pedigrees), while the opposite was observed with the GRAMMAR method, which is fully consistent with our Figures 1a and 1b.
There have been reports about treatment of chondral injuries with bilayer devices of collagen compared with pig collagen type I/III in which the same results were reported with both techniques [18].
To identify predictors of seropositivity, first the association of the potential risk factors (origin, age, sex, management system, presence of domestic cat, presence of dog, way of life of domestic cat, pig feed type, access to dead animal and water source) were analyzed by univariable logistic regression.
The muscles of the crossbred pigs contained type I and IIA myofibers at higher frequency and type IIB at lower frequency than the commercial pigs, except for LT muscle of F2 pigs.
