Abstract The objective of the present study was to characterize maize silage according to chemical composition, maize silage yield, as well as their predicted milk production. A search was made on studies related to maize silage yield, density, chemical composition (DM, CP, NDF, starch), and dry matter digestibility (DMD). In this study, 41 maize varieties from temperate regions and 101 maize varieties from tropical origin were analyzed. The net energy of lactation (NEL Mcal/kg DM), kilograms of milk per t of silage (kg of milk/t DM), and kilograms of milk per hectare of silage (kg of milk/ha) were determined. A cluster (CL) analysis was performed, and six CL of maize silage were obtained. The CL1 included digestibility for dry matter, crude protein,...

Determinaram-se a degradabilidade ruminal da matéria seca (MS) e a fibra em detergente neutro (FDN) e a eficiência de síntese de proteína microbiana em animais que consomem dietas contendo silagem de sorgo com diferentes teores de tanino. A degradação in situ foi avaliada por meio da incubação ruminal de silagens de sorgo contendo nível 1 (N1) e nível 2 (N2) de tanino por 0, 6, 24, 48 e 96h. O delineamento experimental utilizado foi o quadrado latino 4 x 4 duplicado. Os valores de degradabilidade potencial (DP) da MS foram semelhantes entre as silagens, enquanto a degradabilidade efetiva (DE) nas silagens foi reduzida ao adicionar concentrado à dieta. O fluxo de nitrogênio microbiano e a eficiência de síntese de proteína microbiana não foram afetados pela...

Different additives evaluation can contribute fof improving quality and yield of silage production. Therefore, the objective of this study was to evaluate the effects of adding alkalis or urea on fractionation losses due to fermentation and on aerobic stability of sugarcane silage. The experimental design was completely randomized with 13 treatments (6x2) +1: 6 additives (1 or 2 %) plus a control group, and four repetitions per treatment. Data were analyzed by polynomial regression analysis using GLM procedure. The tested additives were sodium hydroxide (NaOH), limestone (CaCO3), urea (CO(NH2)2), sodium bicarbonate (NaHCO3), quicklime (CaO) and hydrated lime (Ca(OH)2). The material was ensiled in 52 laboratory silos (plastic buckets; 12 L capacity) and...

Due to the seasonal cycle of forage, the use of silage to feed animals provides nutrients throughout the year. However, its quality can be improved with the inclusion of additives and other products. Glycerol is a rich source of energy and present a high efficiency of utilization by animals. The purpose of this work was to evaluate the effect of glycerol inclusion on the chemical and fermentation characteristics of corn and sunflower silages. Two silage sources (maize and sunflower) were used and four levels of glycerol inclusion (0, 15, 30 and 45%) based on dry matter were carried out. The experimental design was completely randomized in a 2 x 4 factorial arrangement with five replications. The pH values and chemical composition of corn and sunflower...
