Effects of ensiling whole crop maize with bacterial inoculants on the fermentation, aerobic stability, and growth performance of lambs

The aim of this study was to determine effects of ensiling whole crop maize with the bacterial inoculants Bonsilage mais flussig (BMF) and Lalsil Fresh LB (LFLB) on fermentation, aerobic stability and growth of lambs. Whole crop maize (288 DM g/kg) was ensiled with no additive, BMF or LFLB for 60 days in 1.5 l jars and 3 months in 210 l drums. To follow the fermentation dynamics during ensiling, 1.5 l jars were opened on days 0, 4, 10, 21 and 60 of ensiling for sampling and analysed for pH, water-soluble carbohydrates (WSCs), volatile fatty acids (VFAs), lactic acid, ammonia-N, dry matter (DM), organic matter (OM), metabolizable energy (ME), crude protein (CP), ether extract (EE), ADF and NDF. The aerobic stability of silage was determined by opening jars on day 60 and putting silage in an aerobic environment until day 65. After 3 months of ensiling the 210 l drums were opened, sampled and analysed as for the laboratory scale silos. Silages were fed to 24 South African Dorper lambs ( n = 8/treatment) weighing 20.6 ± 0.62 kg to determine intake in a 63-day experimental period. Results from the small silos showed that the inoculants decreased ( P
