摘要: The aim of this study was to analyse the losses piglets caused by different factors (due overlaying, biting and/or other reasons) within period from birth weaning, reared with their mothers in types housing technology. experiment involved 90 hybrid sows (Czech Large White x Czech Landrace) housed two farrowing houses Each experimental variant 45 litters and demonstrate effect technology on piglets. One (Technology I) modern originated year 2002 while II) older (1994). Piglets were weaned age 28 days. obtained results indicate that overlaying most significant cause piglet till 7 As far as a concerned, there highly differences between both technologies (P < 0.001) 2nd 3rd litter 4th 5th only 0.05). causes days insignificant. compared first week life, 8th day life weaning very low. It demonstrated lactating influenced weaning. In general, it can be concluded more Technology I parameters sow performance better than II, where analysed higher. This indicates is important modernize installed houses.
