Providing Supplemental Milk during Lactation:Effects on Sowsand PigletsHealth and Performance

  One way to handle large litter sizes and to raise as many piglets as possible is to offer ad libitum supplemental milk in addition to sows milk in the farrowing crate.One aspect of this management practice is the reduction of cross fostering,which contributes to an increased level of animal hygiene.Another aspect is the improvement of animal health and welfare.The aim of this study was to investigate the influence of supplemental milk on health and performance of the sow and her litter.In the supplemented group (SUPP),piglets had free access to the supplemental milk,provided by special cups,from the 2nd day of life on.Both groups,SUPP and the control group(CONT).received Prestarter from the 7th day of life.Because of animal welfare aspects and the experimental design SUPP sows retained as many piglets as they had functional teats,whereas CONT sows retained one piglet less than they had functional teats.In SUPP,13.5 pigs,and in CONT,12.4 pigs per sow were weaned after 27 suckling days.The total litter weight was higher in the SUPP group(SUPP:104.9kg; CONT: 96.7kg; P<0.05 ).The average piglet weight was similar in both groups(SUPP/CONT: 7.8 kg; P>0.05).No significant difference was noted between piglets of CONT and SUPP in terms of piglet mortality and occurrence of diarrhea.With respect to the sow,no significant differences were detected for the body-condition-score,the body weight and the backfat thickness between the groups in the period between housing in and out.Via clinical examination,no significant difference was assessed regarding the occurrence of Postpartum Dysgalactia Syndrome in the first three days of life in both groups(SUPP: 8.3% ; CONT: 5.0% ; P=0.7).Ten sows of SUPP,and 14 sows of CONT had mastitis during a later time point of lactation.
