Supply Chain to Industrialization of Pig Excrete by Biotransformation to Increase Corn Performance

Abstract

Abstract:The objective of this work is evaluate manure of Mexican Hairless Pig (MHP) from the three energy levels: high 3.5, medium 2.5 and under 1.5 of metabolizable energy for maintenance (MEM) kg body weight -1 processed as fertilizer in shape in dry, mature and fresh for corn yield. In this work was established a design completely randomized with factorial arrangement 3 x 3 with 3 replications. The excreta of pigs fed with medium and low levels promoted (p ≤ 0.05 y p <0.01) higher content of forage in dry matter (DM) and excreta from high levels increased (p ≤ 0.05 y p <0.01) the content of nitrogen retained in the plant. The manure dry and mature increased 12.5% diameter and 15% leaf area in corn plants, with respect to fresh excreta. The dry manure promoted 6.1% the number of leafs with respect to mature and fresh excreta. The manure dry and mature increased 21.2% content DM in plant, 18.8% cob, and 26% grain with respect to fresh excreta. The dry excrete high level, excelled in most of the variables evaluated, followed by excrete dry from the medium and excrete mature from the level medium and lower.
