The aim of this study was to investigate the eff ect of sows gestating or lactating diets supplemented with a commercial probiotic preparation (liveyeast culture - Saccharomyces cerevisiae, “Actisaf Sc47®”) on their health status, as well as the health status and productivity of their piglets during lactation. A total of 120 sows were divided into three groups: fi rst (G, n=40) and second (L, n=40) group was fed diets with probiotic during pregnancy (G) or lactation (L), respectively. Th e third group (C, n = 40) was the control, which was fed without probiotic. Uterus and/or the udder diseases were manifested in the smaller (p<0.01) proportion in treated group (G=7.5%, L=12.5%) compared to control group (22.5%). Th e incidence of piglets diarrhea was lower (p<0.05) in the treated litters (12.5%) compared to the control litters (27.5 %). The average weaned piglets per litter (p/l) and weaning litter weight (lw) (G=11.6 p/l and 103.6 kg/lw; L=11.1 p/l and 102.8 kg/lw, C=10 p/l and 79 kg/lw) were higher (p<0.01 and p<0.05, respectively) in treated, compared to the control sows. Th ese results show that the use of probiotic signifi cantly improves the health status of lactating sows and piglets, as well as the piglets productivity within lactation.

Numerous studies show significantly reduced sows fertility in the warm period of the year. The aim of this study was to investigate the effect of sows treatment with eCG preparation, 24h after weaning, on the estrous reaction level in the cool and warm season of the year. A significantly (p

SummaryLitter parameters (piglets mortality, weaned piglets per litter, piglet daily gain and body weight at weaning), after peroral treatment of newborn piglets with natural immunomodulator preparations, were investigated at one commercial pig farm in Serbia. Each piglet in 30 litters were peroral treated with 2.5 mL of One Shot immunomodulator preparation within 2 h to 6 h after farrowing, and 1.2 mL Coloron Forte Plus immunomodulator preparation 24 h after One Shot treatment. Starting at day 7 after farrowing up to weaning, piglets were fed the diet for suckling piglets, supplemented with Piggy Guard Forte Plus immunomodulator preparation (15 kg of preparation/t of diet). In the control group (n=30), piglets were not treated with probiotics. Piglets mortality were significantly (P<0.05) lower in the probiotics treated group than in the untreated (control) group (av. 0.27 vs. 0.53 dead piglets per litter, resp.). Average number of weaned piglets per litter was significantly (P<0.05) higher in the treated group (9.16), compared with the control group (8.97). Piglet body weight (av. 8.60 kg vs. 7.53 kg) and daily gain (av. 228 g vs. 193.8 g) from farrowing to weaning, were significantly (P<0.01) higher in the treated group. The results showed that newborn piglets treatment with immunomodulator preparations can decrease piglets mortality rate and increase their growth performance during suckling period.

Deneme grubundaki yavrulara (n=30), oral yolla, doğum sonrası 2 ila 6 saat içerisinde 2.5 mL One Shot immunomodulatör preparatı 24 saat sonrasında ise 1.2 mL Coloron Forte Plus immunomodulatör preparatı uygulandı. Doğum sonrası 7. günden, sütten kesime kadar olan dönemde yavrular, Piggy Guard Forte Plus immunomodulatör içeren başlangıç yemi (15 kgpreparat/ton) ile beslendiler. Kontrol grubundaki yavrulara (n=30) probiyotik uygulaması yapılmadı. Probiyotik uygulanan grupta, kontrol grubuna göre,yavrularda mortalite oranıdaha düşük seviyede tespit edildi (0.27 ve 0.53), (P<0.05).Sütten kesimdeki yavru sayısı, deneme grubunda (9.16) kontrol grubuna göre (8.97) istatistiksel olarak daha yüksek bulundu (P<0.05). Yavruların vücut ağırlığı (8.60 kg ve 7.53 kg) iledoğum sütten kesim arası günlük canlı ağırlık artışı (228 g ve 193.8 g) da muamele grubunda daha yüksek seviyede belirlendi (P<0.01).Bu araştırmanın bulgularına göre, yeni doğan domuz yavrularında, besin yoluyla alınan immunomodülatör katkı maddelerinin, mortalite oranını azaltabileceği ve sütten kesim öncesi büyüme performansını artırabileceği kanaatine varıldı.

Pyometra is one of the most frequent and very grave diseases of the reproductive system in bitches. It occurs around 30 to 60 days following the latest oestrus in bitches that are not pregnant. Bitches older than 5 years have a significantly higher predisposition for this disease than younger bitches. There are also differences between certain breeds in the age at which this disease is manifested in a bitch. The objective of this work was to establish whether the seasons of the year also affect the incidence of pyometra in bitches in the territory of Vojvodina. The occurrence of pyometra was examined in a total of 318 bitches over a course of two years and during the different seasons of the year. It was established that a statistically significantly higher number of bitches (P,05) fall ill with this disease during the seasons September-November (31%) and December-February (28%) than during the seasons March-May (19%) and June-August (22%). The obtained data can serve to secure better prevention and timely diagnoses of pyometra in bitches
