The antimicrobial effect of the ZnO nanoparticles dispersed in polyurethane varnishes was investigated. Antimicrobial activity was evaluated against three bacteria (Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa) and one strain fungi (Sacharomyces cerevisiae) by the 'pour-plate' test. It was shown that the ZnO nanoparticles efficiently inhibit growth of the colonies of Staphylococcus aureus, Pseudomonas aeruginosa and Saccharomyces cerevisiae, but their activity against Escherichia coli was found to be questionable suggesting more detailed research.
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. Keywords: Immunomodulators, Mortality, Growth performance, Preweaning period, Newborn piglets Yeni Doğan Domuz Yavrularında Oral 'Hokovit' Immunomodulatör Uygulamasının, Sütten Kesim Öncesi Parametrelere Etkisi ÖzetYeni doğan domuz yavrularında, doğal immunomodülatör uygulamasının, sütten kesim öncesi parametrelerine (mortalite oranı, sütten kesim oranı, canlı ağırlık artışı, sütten kesim ağırlığı) etkisi, Sırbistan'da ticari bir işletmede araştırıldı. 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.
