Quality of forage oat silage (Avena sativa L.) preserved in three different types of artisan silos

Abstract

This research work was carried out in the "Uywa Illa" cattle ranch of the Huancollo Community of the Tiahuanacu Municipality, with the objective of evaluating the conservation in three types of silos (trench, heap and bag) on the quality of oat silage (Avena sativa L.) at 90 days of conservation. The response variables were: organoleptic characteristics, chemical composition, and nutrient conservation efficiency. The organoleptic analysis indicates 96% good quality silage for trench, bag and 85% silos in heap type silo, while 4% was considered poor quality silage in trench, bag and 15% silos for heap type silo. For analysis of chemical composition data and nutrient conservation efficiency, the completely randomized design was used. The analysis of variance (ANVA) for the content of crude protein, calcium, phosphorus, metabolizable energy and lactic acid, was not significant, the conservation efficiency of crude protein and metabolizable energy the ANVA was not significant.
