Evaluación del rendimiento forrajero y contenido proteico de tres pastos, en diferentes épocas de corte en la Finca Lanzaca, parroquia Gonzanamá, cantón Gonzanamá

Grass is the most complete and economical food for animal feeding, therefore, it is a priority to apply management practices to ensure the availability of forage; the cutting season is an activity that ensures the efficiency of the pasture reflected in multiple factors, such as the quality and quantity of forage. The objective of this research was to evaluate the forage yield and protein content of three species of grasses in different cutting seasons in Lanzaca Farm, Gonzanamá parish, Gonzanamá canton. A Block Design Completely Randomized (DBCA) was established, with 9 treatments and 3 replications; T1 Rhodes grass cut 40 days, T2 Cuba 22 grass cut 40 days, T3 King Grass Green grass cut 40 days, T4 Rhodes grass cut 55 days, T5 Cuba 22 grass cut 55 days, T6 King Grass Green grass cut 55 days, T7 Rhodes grass cut 75 days, T8 Cuba 22 grass cut 75 days and T9 King Grass Green grass cut 75 days. The variables evaluated were: plant height, number of leaves, stem diameter, leaf length and width, leaf area, biomass production, moisture, dry matter, ash and protein. According to the results obtained, King Grass Verde at 75 DDS achieved the highest yield with a height of 1.61 m, number of stems 16.4, stem diameter of 1.60 cm, number of leaves 13.73 leaves/plant, leaf length of 0.94 m, leaf width of 4.23 cm, leaf area of 2.97 cm2 and biomass production of 4.08 kg/FV/m2. The bromatological analysis showed that for humidity the Rhodes grass at 40 DDS presented the highest value with 86.33%; the Green King Grass at 55 DDS obtained the highest value of dry matter with 23.20%; the Cuba 22 at 40 days presented the highest ash content with 17.97% and protein with 17.38%; concluding that the 40 DDS in the three species of cut grasses obtained the highest nutritional value in protein content, becoming an alternative for feeding cattle in the Canton Gonzanamá. Key words: Grasses, forage potential, days of cutting, nutritional quality.
