Valor nutritivo y estabilidad aeróbica de ensilaje del pasto (Brachiaria brizantha) cv. Marandú fertilizado con quelatantes de zinc, boro y magnesio.

Abstract

The research work was carried out in the previous Atty. Luciano Marquinez, located 800 meters from the Chone road in the El Chontillal sector, left bank, in El Carmen Canton, Manabí Province, with the objective of evaluating the nutritional value and aerobic stability of B. brizantha cv. Marandú fertilized with zinc, boron and magnesium chelators; a completely randomized block design (DBCA) was used, with a factorial arrangement (4*4) with 4 repetitions. Factor A being the chelating agents (without chelating agents, zinc chelate, boron chelate and magnesium chelate) and Factor A B cutting ages (20, 25, 30 and 35 days) treatments were analyzed using Tukey's test at 5%. The content of protein, ethereal extract, fiber, nitrogen-free extract, ash did present statistical differences (p > 0.01) in the boron, magnesium and zinc chelate variables. In the chemical composition of Maradú grass silage, simple effects and interactions were highlighted when using ages and chelators, thus demonstrating that age and boron, magnesium and zinc chelators did have a statistical influence, improving biomolecular components and nutritional values. In the aerobic stability both in pH and temperature, simple effects and interactions were highlighted when using ages and chelating agents, thus demonstrating that age and boron, magnesium and zinc chelating agents did have a statistical influence, improving conservation and lengthening the durability of grass silage.
