ABSTRACT This study aimed to evaluate the effects of two maturity stages of whole-plant corn at harvest (32.1 or 42.5% dry matter (DM)) and a commercial microbial inoculant composed of L. buchneri and L. plantarum at concentration of 110,000 CFU/g of fresh forage (1.1 × 105 CFU/g FF) on fermentation losses, aerobic stability, chemical composition, and digestibility of starch and neutral detergent fiber (NDF). A factorial and randomized design was used (two DM contents, both with or without inoculant), with […]

The objective of this trial was to evaluate chemical additives and a bacterial inoculant on the inhibition of alcoholic fermentation and reduction of losses in sugarcane silages. Treatments were (doses on a fresh forage basis): without additive (control); urea (10 g/kg); urea (5 g/kg) + sodium benzoate (0.5 g/kg); sodium benzoate (1 g/kg); urea + ammonium sulfate in a 9:1 relation (10 g/kg); Lactobacillus buchneri (5 × 104 cfu/g). Silages were produced in 10.16- × 30-cm PVC tubes, provided with […]

The objective of this work was to compare losses, microbiological dynamics and nutritional and fermentative alterations in silages of fresh or burned sugar cane treated or not with Lactobacillus buchneri during storage period. Treatments were fresh sugar cane or treated with L. buchneri and sugar cane burned or treated with L. buchneri, evaluated with 0, 1, 4, 7, 14, 28 and 56 days of fermentation, in three replicates per treatment. Only before ensiling it was observed significant difference in the […]

The objectives of this experiment were to evaluate the performance of young bulls fed total rations prepared with additive treated or untreated sugarcane silages and evaluate the additive effects on silages fermentation. Thirty young Canchim bulls averaging 312 kg were allotted to a completely randomized experimental design to evaluate three types of isoproteic and isoenergetic rations (roughage:concentrate ratio of 35:65): ration with silage without additive (control), ration with silage treated with urea (5 g/kg of fresh forage – FF) + […]

An experiment was performed aiming at evaluating the performance of dairy cows fed sugarcane silages treated with additives compared to cows fed fresh forage. Twenty-four Holstein cows were grouped in blocks of three cows, according to parity order and milk production level, in multiple 3 x 3 Latin Square design to evaluate three types of ration (63% roughage and 37% concentrate in dry matter – DM): ration with silage treated with urea (5.0 g/kg of fresh forage – FF) + […]

The experiment was carried out to evaluate the performance of high produce animals fed rations with different sources of forage, what resulted in the treatment: fresh sugarcane (SC), sugarcane silage inoculated with L. buchneri (SCS), corn silage (CS) and mixture of fresh sugarcane and corn silage (SCCS). The experiment was carried out in a 4×4 latin square design with periods of 21 days, and the last 7 days, of each period was used for sample collections. Besides the performance evaluation, […]

The objective of this trial was to evaluate chemical and bacterial additives on inhibition of ethanol production, reduction of DM losses and on in vitro digestibility improvement of sugar cane silages. Treatments were (wet basis): without additive – control; urea – UR – (0.5; 1.0; 1.5%), NaOH (1; 2; 3%), calcium propionate – PROP – (0.05; 0.1; 0.2%), sodium benzoate – BENZ – (0.05; 0.1; 0.2%), potassium sorbate – SORB – (0.015; 0.03; 0.045%), Lactobacillus plantarum – PLA – (1 […]
