Establishment of a hydroponic green forage bank as feed supplement for bovine cattle of Casanare in drought age Establecimiento de banco de forraje hidropónico como suplemento alimenticio para ganado bovino del Casanare en época de sequía

Abstract

Cattle ranching in Casanare has been affected by adverse climatic conditions such as prolonged droughts and floods that have caused; low availability of food, nutritional shortage of forages and pastures on farms. Therefore, in this research a strategy was established to mitigate the lack of food by means of a hydroponic forage bank in order to optimize and stabilize the production of cattle feed in Casanare. In this way, the objective of this study was to evaluate and compare, through the T student test, a Zea Maiz variety of Guacavia plant in two types of fertilizers; "Chemical fertilization T1 and organic fertilization T2", was analyzed; Height, gain of fresh biomass and conversion efficiency, for this daily measurements were made in height where 5 seedlings per tray were taken and in biomass the daily weight to the forage mat, in turn to know the nutritional value was sent 500 gr of sample of each treatment for its later bromatological analysis. In both treatments there was no significant effect (p> 0.05) on the variables, on the other hand, 2 kg of seed was planted per tray and on the eleventh day it was obtained in the treatment T2 9.1kg of biomass, 38.7 cm of height and 11.5% of protein based dry, while in treatment T 1 achieved better results, 11.2 kg of biomass, 45 cm in height and 19.1% of protein based dry.
