A logistic regression analysis revealed that the location (province), the number of slaughtered cattle, the flooding of pastures, free access of cattle to surface water and the proximity of wastewater effluent were significant explanatory variables for bovine cysticercosis to be recorded in a herd.
The monthly number of slaughtered finishing pigs was about 15000.
These slaughter houses covered 65% of the total number of slaughtered lambs in Sweden during the most intense slaughter period (August to October) in 2008.
Prevalence per species, for each country, was applied to the estimated number of slaughtered animals per year, with 2004 livestock numbers obtained from the FAOSTAT database (18 ).
Condemnation rates were calculated by dividing the total number of pairs of lungs condemned under the pneumonic lung classification each month by the total number of slaughtered bovines for each animal class (e.g., calves, cows, heifers and steers).
A sampling strategy for monitoring antimicrobial resistance was developed in 2008, which considered the geographical distribution and size of the slaughterhouses, and the number of slaughtered pigs in Switzerland [ 23].
Of the total number of slaughtered cattle, 403,290 organs/portions were condemned for various reasons with the top four reasons being evidence of pneumonia, liver abscesses, nephritis and "parasitic livers".
The offset of the negative binomial model was the natural log of the total number of slaughtered cattle for the abattoirs included for each sentinel site selection approach for each animal class and month-year period during the study period.
Because we were unable to identify the number of breeding pigs in China, we used an estimate based on the ratio of breeding pigs to number of slaughtered pigs provided in Mellon et al. For poultry, our estimates suggest that slightly more than 4.5 million kg [9.9 million lbs] of antimicrobials were used in production for 2012 (Table 3).
Given that the limited replicate number of slaughtered animals in the present study may be not enough to generate a definitive conclusion, further investigation with more number of samples is required to determine the appropriate fish oil supplementation level, duration, and the precise mechanisms by which long chain (n-3) PUFA affect piglets' immunity and growth.
