The twenty studied genotypes of sorghum were cultivated and ensiled at 104 days of age, at dough grain phase, using “PVC” lab silos, presenting 10 cm diameter and 40 cm length. The silos were opened at 150 days after ensiling. A completely randomized experimental design was used. In the studied material (fresh and ensiled) the values of neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose, cellulose, lignin, total ash, dry matter (DM), crude protein (CP) and alcool soluble carbohydrates […]

The objective of this experiment was to evaluate the forage potential of new selected clones of elephantgrass. The evaluation was conducted at the Dairy Cattle Research Centre – EMBRAPA, Coronel Pacheco, Minas Gerais, for two consecutive years. Twenty selected clones obtained by the elephantgrass breeding program were evaluated, and two traditional cultivars Cameroon and Taiwan A -146 were used as control. The experimental procedure was a randomized block design with four replicates. The fertilization for both establishment and maintenance was […]

The production and quality of forage of annual temperate grasses mixtures under continuous grazing condition were evaluated. The mixtures used were: T1 – Triticale (X Triticosecale) plus ryegrass, T2 – Oat (Avena strigosa) plus ryegrass, and T3 – Triticale plus oat plus ryegrass. Broadrast sowing occurred at 04/21/95, being the area fertilized with 200 kg/ha (05-30-15). The broadcast fertilization was of 175 kg/ha of nitrogen in urea form and it was subdivided in four applications. The establishment of the pasture […]

The objective of this experiment was to evaluate the fermentative quality of sorghum silage of small, medium and high size with different stem+leafs/head proportions (100:00, 80:20, 60:40, 40:60, 20:80, 00:100), by means of lab analysis. The whole plant was used as control. The hybrids were cultivated and ensiled at 104 days of age in PVC lab silos measuring 10-cm of diameter by 40-cm of length (three replications per treatment). Silos were opened 56 days after the ensilage. The contents of […]
