Biodisponibility of inorganic material of mombaza paste under complementary fertilization with zinc metalosate

Abstract:

The present research was carried out in two sites. The first one corresponded to the agronomic phase in the province of Orellana, in the Joya de los Sachas canton, and the second phase consisted in determining the rumen degradability (bioavailability) of the inorganic matter by developing it in the laboratory Of Rumiology and Nutritional Metabolism of the Quevedo State Technical University, Faculty of Animal Sciences, located at Km. 7 via Quevedo - El Empalme, Los Ríos Province. The objective of this study was to evaluate the effect of three levels of zinc metalosate on the bioavailability of inorganic matter in Mombaza grass. A randomized complete block design with a 3 x 3 factorial arrangement was used. A total of 9 treatments were used that were distributed in 3 random blocks (fistulated Brahman bulls). The factors under study were zinc metalosate (0, 1 and 2 liters ha-1) and age cut or regrowth (28, 35 and 42 days) and the variables under study Ash bioavailability (inorganic matter degradability) Ruminal incubation times (0, 3, 6, 12, 24, 48 and 72 hours). The bioavailability of the inorganic matter of Mombaza grass at all times of ruminal incubation was positively influenced by the use of zinc metalosate, with a level of 2 lts ha-1. In addition, the same trend was achieved at 42 days from the regrowth cut of Mombaza grass and in the interaction effect was highlighted 2 lts ha-1 x 42 days of cut.
