Practical microalgal supplementation: reducing ammonia emission from manure in commercial layer production.

ABSTRACT:

Background

The rapid development of intensive layer breeding has intensified odor pollution that must be paid attention to for the green transformation of the industry. This study used Jingfen No.6 laying hens as the model to systematically evaluate the regulatory effect of compound microalgal powder (Chlorella vulgaris:Spirulina platensis:Haematococcus pluvialis = 3:1:1, 1:3:1, 1:1:3) on ammonia (NH₃) emissions from laying hen manure.

Results

Through analysis of the static NH₃ production in manure, it was found that the NH₃ emissions within 24 h in the experimental group with 0.50% compound microalgal powder added were reduced to 6.27-16.84 mg (vs.

Control

28.29 mg), achieving a 40.47%-77.84% reduction. GC/MS and 16S rRNA sequencing a
