Valor nutricional y degradabilidad ruminal in situ del banco forrajero mixto cuba 22 (Pennisetum sp) y KUDZU (Pueraria phaseoloides)

In order to determine the nutritional value and ruminal degradability of the Cuba 22 (Pennisetum sp) and Kudzu (Pueraria phaseoloides) mixed forage bank, a study with four treatments was proposed: T1 (75% Cuba 22 + 25% Kudzu), T2 ( 50% Cuba 22 + 50% Kudzu), T3 (25% Cuba 22 + 75% Kudzu) and T4 (100% Cuba 22) distributed using a completely randomized block design (DBCA), the biomass production variables were estimated, by weighing the legumes in the field, nutritional parameters of dry, organic and inorganic matter, protein, and total fibers. The dynamics and in situ rumen degradability parameters of dry matter were evaluated in association with Cuba 22 and Kudzu. The results showed that treatment T4 (Cuba 22) produced the highest amount of biomass with 14.55 kg/m². In dry matter, T3 was the most nutritious due to its low content of inorganic matter (10.89%) and high organic matter (89.11%). In protein, T1 presented a better percentage (15.21%); while, in fiber, Q4 had the highest level (33.29%). In the rumen degradability, the digestibility values at 12 hours showed that T3 had a better average (46.46%). Consequently, the high digestibility of Cuba 22 and Kudzu facilitates degradation and helps microorganisms in the digestive tract; therefore, the hypothesis that this association improves the nutritional composition of the grass as feed for cattle is accepted.
