Abstract

In a random block design with six replicates, the influence of the regrowth age (30 to 75 d) and the climatic factors were evaluated in the nutritive quality of the pasture Panicum maximum cv Mombasa. The experiment was conducted in the trimesters January-February-March (dry season) and May-June-July (rainy season), on soil of the brown type with carbonate, without irrigation or fertilization. The highest
correlations were between the indicators quality and age, mean temperature, maximum relative humidity and rainfall. The equations of linear regression during the rainy season had R2 that varied between 0.97 and 0.99. DM, NDF, cellulose, hemicellulose, and in situ digestibility were outstanding. The lowest standard errors of estimation were obtained in NDF, cellulose, and hemicellulose. It is concluded that the regrowth age and the climatic conditions had marked effect on the nutritive value. Further studies on these indicators are recommended in different types of soils, in the edaphoclimatic conditions of the Cauto Valley, with the aim of having more information available.
Key words: Panicum maximum, nutritive quality, climatic factors.
