The effect of a postpartum treatment with ceftiofur sodium (Naxcel~(TM) sterile powder) and prostaglandex F_2 alpha (Lutalyse~(TM) sterile solution) on a pig farm in the republic of Korea

摘要

The benefits of using proslaglandin F_2 alpha (Lutalyse~(TM) Stenle Solution) for farrowing induction have been recognized by swine producers for years. Recently, it has also been indicated that early post-farrowing use of Lutalyse improves productivity. In Korea, sows with low fertility rate and aberrant vaginal discharge are commonly observed. Therapy with systemic or intrautenne use of antibiotics are used, but has not been proved effective. The objective of this study was to evaluate an intramuscular treatment regime of ceftiofur sodium (Naxcel~(TM) Sterile Powder) and Lutalyse on total piglets bom, days from farrowing to estrus and vaginal discharges post-farrowing. The study was conducted on a Korean farm with a history of poor reproductiveperformance. This farm experienced problems of moderate endometritis in its sow herd (vaginal discharges), and frequent colibacillosis in its piglets pre-weaning. A total of 300 sows were randomly allocated to two groups at parturition. The treatment group were given (IM) 8 ml of Naxcel (400 mg ceftiofur) immediately post-partum and 2 ml of Lutalyse (10 mg of dinoprost) 24-48 hours posipartum. Sows in the control group were not given any treatment. Computerized systems were used to keep records for thepig performance during the study.
