AIMS To evaluate the persistence of Mycobacterium avium subsp paratuberculosis (Myco. paratuberculosis), Salmonella enterica serotype Typhimurium (Salm.Typhimurium) and a commensal Escherichia coli (E. coli) isolate under the low pH and high organic acid (OA) conditions of ensiling of forages. METHODS AND RESULTS Decay rates and the time required to obtain a 90% reduction in cell concentratio...

A study was carried out to investigate the effect of restricting silage feeding on time of calving and calving performance in Holstein-Friesian cows. In the treatment group (n = 1,248 cows, 12 herds) silage feeding commenced in the evening (17:00 to 20:00 h), after a period of restricted access (2 to 10 h) while in the control group ad-libitum access to silage was provided over the 24 h period ...

The effect of replacing wilted grass silage (GS) with pea-barley intercrop silage (PBS) on feed intake, diet digestibility and milk production was studied with 8 multiparous Ayrshire-cows in a replicated 4 × 4 Latin square experiment. Proportion of PBS was 0 (PBS0), 33 (PBS33), 67 (PBS67) or 100 (PBS100) % of silage dry matter (DM). The DM content was 559 and 255 g kg-1 for GS and PBS. Crude pr...

This study examined the effects of two L. plantarum starters that are physicochemically different on Panicum maximum silage fermentation. The grass was inoculated with approximately 10 cfu/g of the starter 6 culture. Aerobic stability, chemical composition and acceptability of the silage produced by ruminant were monitored at 15 days intervals for 60 days. The studies observed rapid drop in the...

Bu çalışmada mısır silajına katkı maddesi olarak yemlik keçiboynuzu kırığı kullanılmıştır. 60 günlük silolama sonucunda oluşan silajların besin madde kompozisyonu, fermantasyon parametreleri ve in vitro değerleri aerobik stabilitesi incelenmiştir. Oluşan kuru içerikleri %23.66 ile 25.73 arasında bulunmuştur. Ham kül %11.01 14.77 ham protein %7.29-8.09 Silajların ADF NDF sırasıyla %12.97-14.82 2...

INTRODUCTION At the Forage Conservation in the ‘80s Conference, Zimmer (1980) concluded that the gaps between “proven technology” and “real efficiency” of silage programs on the farm too often were too wide. Almost 30 years later, the silage industry is still faced with the challenges of implementing silage technologies, both old and new. A large segment of this industry is described as the “Si...

The methane potential of nine varieties of fresh maize harvested at three different times and of maize silage was experimentally determined in batch assays. The ultimate methane productivity in terms of volatile solids (VS) was determined as 213.94-313.63, 195.88-334.81 mL/g VS from several fresh and silage maize in three stages, respectively. The average specific methane yield of wax ripeness ...
