- Abstract
The objective in this research was to evaluate the phenology, production and to determine nutritional chemistry composition and in vivo digestibility of A. pintoi and, to establish standards for determining the nutritional value and production based according to the chemistry composition of the plant. The phenological evaluations were carried out at ranch ESPE and in vivo digestibility was executed in Animal Science Faculty from ESPOCH. In the first phase were used experimental plots 10 by 15 m. in four replications. In the second phase the experimental unit was an ovine (n=4). In both tests were used at random experimental designs with a linear additive standard applying a significance level of 5%. It was executed an correlation analysis and linear regression among phonological variables, chemistry composition, digestibility and energy. The whole analysis were carried out with SPSS 10 Statistical package. The greatest productions of green fodder and dry matter (DM) per hectare were obtained at cutting to 75 days with 47,730 and 12,480 kg ha-1, respectively. On the other hand, in chemistry composition of grass protein and in vivo digestibility of dry Matter (DM), the clipped forage to 30 days obtained the greatest values with 24.50 and 66.42%, respectively. The maximum value of net energy for lactation (NEL) was achieved at 30 days cutting reaching 1.51 for decreasing to 1.24 Mcal NEL kg-1 to 75 days.
