A feeding trial was performed on 1400 Big-6 turkey toms divided into experimental groups subject to the use of dietary supplements. The ain of this study was to evaluate the efficacy of the probiotic supplement Bactocell, containing lactic acid bacteria Pediococcus acidilactici, and lactose, administered to turkeys separately or in combination, as well as a formic acid supplement. The addition of the probiotic under test (lactic acid bacteria Pediococcus acidilactici) to diets for turkeys contributed to higher daily gains and lower feed consumption per kg weigh gain only during the first 12 weeks of their life. Diet supplementation with lactic acid bacteria and lactose reduced mortality rates. A slaughter value analysis revealed only a slightly (by approximately 1%) higher content of breast muscle and a lower content of thigh muscle in birds fed diets supplemented with lactic acid bacteria. Turkeys receiving lactic acid bacteria or lactose and a combination of both these supplements were characterized by a higher fat content of meat and slightly lower pH values, whereas meat from turkeys fed lactose-supplemented diets was darker in color. The addition of formic acid Acidum formicum to diets for turkeys contributed only to lower mortality rates.
This research was carried out to determine the effects of bacterial silage inoculant using as silage additives on the fermentation charakteristics, cell wall contents and aerobic stability of maize silages. Maize silage was harvested in the 89 (BBCH) developmental ripening stage. Biological additive was used as additive which contains Enterococcus faecium PCM 1858, Pediococcus acidilactici PAL-34, Lactobacillus plantarum PCM 493, Lactobacillus buchneri DSMZ 5987, Lactobacillus rhamnosus PCM 489, Lactobacillus brevis PCM 488, Lactobacillus lactis PCM 2379. Maize was ensiled in 4 dm3 special PCV laboratory microsilos with a cover permitting gaseous products. The microsilos were stored at 10–15±2şC undr laboratory conditions. Microsilos from each group were sampled for microbiological and chemical analyses on the days 3, 14, 21 and 60 after ensiling, whereas aerobic stability was determined after 7 days. As a result, bacterial silage inoculant improved fermentation, decreased cell wall contents, deoxynivalenol (DON) concenration, do not improved aerobic stability of maize silage after 7 days exposure to air.
