Chemical composition and fermentative losses of mixed sugarcane and pigeon pea silage

Abstract

Adding legumes to sugarcane silage is a strategy used to improve silage quality and reduce losses. This study's objective was to evaluate the chemical composition and fermentation profile of silages sugarcane and pigeon pea. A completely randomized design was used, with five treatments and four replications. The treatments consisted of sugarcane silage with increasing pigeon pea proportions (0, 25, 50, 75 and 100%). The forages were ensiled in experimental microsilos that remained closed for 60 days. Their chemical compositions were evaluated by determining the pH value and dry matter, crude protein, neutral detergent fiber, acid detergent fiber, hemicellulose, cellulose and lignin content. Fermentation profiles were evaluated by determining the effluent, gas, and total dry matter losses and dry matter recovery of the silage. Including pigeon pea in sugarcane silage decreases the hemicellulose content and increases the crude protein, acid detergent fiber and lignin content. Fermentation losses are reduced by adding pigeon pea to sugarcane silage with reduced effluent and gas losses and increased dry matter.

Perfil fermentativo, calidad nutricional y estabilidad aerobia de ensilajes mezclados de hierba elefante (Pennisetum purpureum Schum) y maní forrajero (Arachis pintoi)

“…Este efecto era esperado debido a la capacidad llenadora de las leguminosas, que presentan altos niveles de ortofosfato y sales de ácidos orgánicos y alta concentración proteica, fatores responsables por la capacidad llenadora de una planta forrajera (23). La inclusión de maní forrajero a partir del 40% proporcionó a los ensilajes valores de pH dentro de la faja considerada adecuada para ensilajes debidamente fermentadas (3.8 a 4.2) (24). Ese resultado difiere de los hallazgos de Gomes et al (25) que observaron que niveles a partir del 25% de maní forrajero en ensilajes de hierbamarandu proporcionaron a los ensilajes valores de pH dentro de los límites establecidos.…”

Mixed silages of sugarcane and forage peanut treated with Lactobacillus buchneri

“…The pH value obtained for exclusive sugarcane silage (3.44) (Table 3) was similar to the values reported by Cardoso et al (20) and Jesus et al (21) of 3.41 and 3.39, respectively, and indicated a good fermentation quality of silages, mainly due to the relatively low contents of butyric acid and acetic and propionic acids in inoculated silages. Sugarcane silages with the addition of legumes generally have higher pH values, as observed by Pereira et al (22) in analyses of sugarcane and pigeon pea mixed silages, which were also fitted by a quadratic equation.…”

Fermentation profile and nutritional quality of silages composed of cactus pear and maniçoba for goat feeding

“…The total dry weight loss during the ensiling period was determined by the difference between the weight of the initial (FMop – forage mass at opening, in kg) and final mass (FMcl – forage mass at closing, in kg) in the silos. The dry matter recovery (DMR) of the silage was estimated using the equation DMR = (DMop × 100)/DMcl, where DMop = DM content at opening; and DMcl = forage DM content at closing (Pereira et al ., 2019). Samples were taken at all silos opening times to determine the chemical composition and fermentation profile of the silages.…”
