The current study aimed to evaluate the application effects of the preactivated Lactobacillus buchneri and urea on the fermentative characteristics, chemical composition and aerobic stability in corn silages. The design was completely randomized, in a 6 × 5 factorial arrangement, with six types of additive and five opening times. The treatments consisted of corn silage; corn silage with freeze-dried inoculant; corn silage with freeze-dried inoculant +1.0% urea; corn silage with activated inoculant; corn silage with activated inoculant +1.0% urea, and corn silage with 1.0% urea. Populations of lactic acid bacteria stabilized at the 70th day, with average values of 8.91 and 9.15 log cfu/g for corn silage with freeze-dried inoculant +1.0% urea and corn silage with freeze-dried inoculant, respectively. In contrast, the silages without additives showed significantly lower values of 7.52 log cfu/g forage at the 70th day. The silages with urea (isolated or associated with the inoculant) increased the total nitrogen content. The maximum temperature values were highest in the corn silages without additives, indicating that these silages were more prone to deterioration. The use of Lactobacillus buchneri activated proved to be more efficient in improving the fermentative profile of corn silages than the freeze-dried inoculant. The use of urea as an additive reduced the losses and improved the nutritional value and aerobic stability of corn silages. Additionally, the combination of Lactobacillus buchneri activated and urea may be used as a technique to improve the fermentative profile, chemical composition and aerobic stability of corn silages.

Abstract We evaluated the effects of applying a combination inoculant to 4 corn hybrids harvested at high moisture on their nutritive value and microbial populations. The treatment design was the factorial combination of corn hybrids ensiled with (INO) and without (CON) inoculant. The hybrids were TMF2R737 (MCN), F2F817 (MBR), P2089YHR (PCN), and PI144XR (PBR), ensiled at dry matter (DM) concentrations of 30.5, 26.3, 31.1, and 31.5%, respectively; MBR and PBR were brown midrib mutants (BMR). The inoculant contained Lactobacillus buchneri and Pediococcus pentosaceus (4 × 10 5 and 1 × 10 5 cfu/g of fresh corn). The experiment had a complete randomized design with treatments replicated 6 times. Corn was treated or not with inoculant, packed into 7.6L bucket silos, and stored for 100 d. At d 0, the relative abundance (RA, %) of Enterobacteriaceae was lower in PBR vs. the other hybrids [51.3 vs x= (average of) 58.4] and in the case of fungi, incertae sedis (i.s.) Tremellales and Mucoraceae were more and less abundant, respectively, in conventional hybrids vs. BMRs (x= 25.8 vs. x= 13.9 and x= 3.64 vs. x= 7.52; P < 0.04). After ensiling, INO had higher LAB (9.3 vs. 7.1 log cfu/g of fresh corn) and acetic acid (3.44 vs. 1.32% of DM) and lower yeast (3.1 vs. 4.6) and molds (1.5 vs. 3.0), and also extended the aerobic stability (582 vs. 111h) but decreased DM recovery (95.6 vs. 97.4%) vs. CON (P < 0.02). Inoculation reduced bacterial phylogenetic diversity (6.75 vs. 14.4) but increased fungal observed taxonomical units (46 vs. 20) vs. CON (P < 0.01). Also, a higher relative abundance (RA) for Lactobacillaceae (99.2 vs. 75.7%) and lower for Enterobacteriaceae (0.28 vs. 9.93) was observed due to inoculation (P < 0.001). For fungi, INO had a lower RA compared to CON for Monascaceae (12.6 vs. 44.7) and increased i.s. Tremellales (8.0 vs. 1.2) and i.s. Saccharomycetales (6.4 vs. 0.3%; P < 0.006). Inoculation changed the diverse bacterial community found in the phyllosphere across hybrids to a taxonomically uneven one dominated by Lactobacillaceae. In the case of fungi, INO application increased the fungal diversity at d 100 mainly by reducing the dominance of Monascaceae vs. CON. In conclusion, the INO treatment overwhelmed the disparate microbial populations found across BMR and conventional hybrids ensiled at low DM concentrations and ensured a significant concentration of acetic acid that modified fungal populations and in turn extended the aerobic stability of all hybrids.

This study was conducted in Nutrition Lab. to investigate the effect of the type and level of substitution of urea with ruminant manure, M (sheep, cow and buffalo) on basis of nitrogen (N) content on the nutritive value of rice straw silage (RSS). Accordingly silages were nominated as, S-RSS, C-RSS and B-RSS. Urea (U) was substituted with dried manure at 6 combinations, 100:0, 90:10, 80:20, 70:30, 60:40 and 50:50 of U:M. Silage samples were prepared by treating chopped straw with pre-treated solution contained 10% low quality debis and 2% urea. Results showed that lower (P˂0.01) DM loss (11.4%) was observed in S-RSS, and with addition of urea only (3.6%).        Samples of S-RSS and C-RSS recorded higher (P˂0.01) Fleig points (Fp) as compared with those prepared by the addition of B-RSS, 60.42, 55.58 and 49.59 respectively. Reduction (P˂0.01) in this parameter was noticed in samples prepared with a combination of 100:0. Aerobic stability (AS) was a reduced (P˂0.01) in samples prepared by addition of S-RSS by 15 and 13 hours in comparison with samples of C-RSS and B-RSS respectively. Samples prepared with combination of 100:0 were prior (P˂0.01) as compared with other samples.        Results also showed an increase (P˂0.01) in in vitro digestibility of organic matter (IVOMD) in samples of S-RSS in comparison with samples prepared by addition of C-RSS and B-RSS, 49.99, 44.59 and 42.77% respectively. Samples prepared with combination of 100:0 recorded lower (P˂0.05) in vitro digestibility of dry matter (IVDMD) as compared with combinations of 70:30 and 60:40 of U: M, 40.52, 45.36 and 45.94% respectively.
