Effect of applying molasses or inoculants containing homo-fermentative or hetero-fermentative bacteria at two rates on the fermentation and aerobic stability of com silage
(American Dairy Science Association, 2009) Huisden, C. M.; Adesogan, A. T.; Kim, S. C.; Ososanya, T.
This study determined how the fermentation and aerobic stability of corn silage are affected by treatment with molasses or 2 dual-purpose inoculants applied at or above the recommended rate. Corn forage (DeKalb 69–70) was harvested at 39% dry matter (DM) and ensiled after treatment with no additives (control, CON), molasses (MOL), Buchneri 500 inoculant, or Pioneer 11C33 inoculant. Molasses was applied at 3% of forage DM. Buchneri 500 was applied at the recommended rate of 8 mg/kg fresh forage to supply 1 × 10(5) cfu/g of Pediococcus pentosaceus 12455 and 4 × 10(5) cfu/g of Lactobacillus buchneri 40788 (BB) or at twice the recommended rate (DBB). Pioneer 11C33 inoculant was applied at the recommended rate of 1.1 mg/kg fresh forage to supply 1 × 10(5) cfu/g of a mixture of Lactobacillus plantarum, L. buchneri, and Enteroccocus faecium (PN) or at twice the recommended rate (DPN). Each treatment was applied in quadruplicate and the treated forages were ensiled within 20-L mini silos for 135 d at 18 to 35°C. Molasses-treated silages had greater ash and starch concentrations than CON silages and greater lactate and ethanol concentrations than other silages. Like CON silages, MOL silages had high yeast counts (>10(5) cfu/g); consequently, they deteriorated within 30h as shown by temperature increase. Inoculant-treated silages had lower lactate to acetate ratios than CON or MOL silages largely because they had greater acetate concentrations. Consequently, all inoculant-treated silages had fewer yeasts (<10(5) cfu/g) and were more stable (>30 h) than CON and MOL silages. When applied at recommended rates, PN and BB had similar effects on silage chemical composition, fermentation, fungal counts, and aerobic stability, except for a lower lactate concentration in PN silages. Concentrations of VFA, and NH3-N, pH, and extent of aerobic stability were similar for PN, DPN, BB, and DBB silages. However, lactate concentration was greater in DPN than in PN. In conclusion, MOL application increased ethanol and lactate concentration and did not improve aerobic stability. Both dual-purpose inoculants made the fermentation more heterolactic and thereby improved the aerobic stability of corn silage. Doubling the rate of application of either inoculant did not further improve fermentation or aerobic stability.
Haematology of pregnant West African dwarf ewes fed siam weed-based rations
(Animal Science Association of Nigeria, 2004) Anurudu, N. F.; Babayemi, O. J.; Ososanya, T.
There is relatively scanty information on normal blood values for sheep in Nigeria as regards the nature and the level of forage inclusion in the diets. The study was set up to assess the effects of siam weed on blood chemistry of pregnant West African Dwarf (WAD) sheep. Sixteen WAD sheep that have lambed once were allocated in a completely randomized design to four diets with different levels of siam weed leaf meal (SWLM) diets inclusion: 0% (Diet A), 15% (Diet B), 30% (Diet C) and 45% (Diet D). Variations in haematological parameters due to treatments were inconsistently significant except for Erythrocyte/ red blood cell (RBC). The Leukocyte/white blood cell (mm3 xlO3) varied from 5.64 (diet B) to 8.81 (diet A) in the last trimester. The lowest packed cell volume (28%) was obtained for sheep on 30% siam weed leaf meal (SWLM). Erythrocyte values were low ranging between 5.71 and 6.37. White blood cell was normal and ranged from 5.64 in 15% to 8.81 in 0% SWLM. The values for packed cell volume slightly increased in animals on diets 0% and 45% SWLM at the end of pregnancy while those of 15% and 30% remained normal. Mean corpuscular volume (ranged 47.50 - 53.25) was beyond the normal range at late pregnancy. The results showed that pregnant sheep could tolerate the siam weed leaf meal at levels between 15 and 45% dietary inclusion without a significant alteration of the blood constituents.
