Aim of the paper was graphical presentation of family farms reproduction results over longer period of time. Besides results of a breeder, graphs contain also results of the most suddessful pig farm in Slovenia which are used as a standard and the averages of family farms for comparison reasons and easier interpretation. Fertility traits were considered separately for gilts and sows, while replacemnet rate was discussed for both categories together. Three family farms as examples were used: with good and bad results and one with inappropriate age structure of sow herd. The results were interpreted, used to search for potential mistakes and possible improvements were shown. We tried to stimulate breeders to self-controlled interpretation of their own results.
F.04 Increase of the technological level
COBISS.SI-ID: 2961800Porcine reproductive and respiratory syndrome (PRRS) is viral infection that plagued to swine industry worldwide and is considered the most economically devastating disease of modern swine production. The disease is most commonly spread between the farms by the introduction of positive pigs, with infected semen and with other routes. Infected animals shed virus in saliva, nasal secretion, urine, semen and feces. The only completely consistent clinical feature of PRRS is that there are no consistent features. The reproductive failure and respiratory problems were noticed as well as decrease of production results.
F.01 Acquisition of new practical knowledge, information and skills
COBISS.SI-ID: 3463546Porcine reproductive and respiratory syndrome (PRRS) is economically significant disease. The inability to successfully control PRRS on the farm by traditional methods such as vaccination and “all in all out” sistem has led to a growing interest for eradication. A variety of strategies has been described for eradication: natural spread, total depopulation/repopulation, mass vaccination, serumization, test and removal. The proper model of eradication depends on herd size and prevalence of the disease. For successful eradication, the herd closure and strict biosecurity protocols should be followed.
