HENG MEI Intelligent Manufacturing DNA Sexing Workflow for Pigeons and Parrots

DNA sexing connects the bird identity to a suitable specimen, extracted DNA and a species-appropriate assay. HM-P16 provides thermal cycling and real-time fluorescence detection. Keep positive, negative and sample-adequacy controls within the defined test procedure.

HM-P16 is part of the HENG MEI Intelligent Manufacturing range supplied by Shandong Hengmei Electronic Technology Co., Ltd.

How the measurement works

HM-P16 performs thermal cycling and real-time fluorescence detection for a species-appropriate avian DNA sexing assay. Its 16 reaction positions and two optical channels must match the kit, vessels and control layout used for pigeon or parrot specimens.

Set up the analytical workflow

1. Assign the bird and specimen identifiers using the sampling procedure.
2. Extract DNA and prepare the species-appropriate reaction with its controls.
3. Run the assay using the prescribed cycling and fluorescence settings.
4. Review controls and interpretation criteria before issuing a sexing report.

Technical configuration

Calculate reportable capacity from the run layout

With 16 positions, a layout containing two assay controls and duplicate reactions for each bird accommodates seven birds. Additional controls or repeats reduce that allocation. Calculate reagent demand from reaction count and include the method’s preparation allowance when making a master mix.

Interpret the assay pattern with all controls

The validated assay specifies the expected signals and how they relate to sex classification for the species. Review sample adequacy and the positive and negative controls before issuing a report. Preserve the link from the bird and specimen to the extraction and reaction positions so any result can be reconstructed.

Protect identity through an avian sexing workflow

Assign the bird identifier at specimen collection and carry it through extraction, reaction setup and reporting. Use the sampling method and assay coverage appropriate to the species. Map controls and sample reactions before dispensing, and reconcile the run layout with the specimen list. Review the complete control pattern and the assay interpretation rules before assigning a sex classification. When the result is inconclusive, follow the defined repeat or resampling route and retain the reason. This gives breeders and testing teams a traceable result associated with the correct bird.

Choose the assay with the bird species and specimen

Establish the validated species coverage and sampling procedure before selecting reagents. Plan DNA extraction, specimen identification and the required assay controls. Match fluorescence dyes and reaction volumes to the instrument. Define the handling of inconclusive results so another specimen or repeat analysis can be requested when the assay procedure requires it.

Investigate unexpected results

Keep a usable analytical record

Retain these details with the result so the preparation, measurement and subsequent review can be reconstructed.

• Bird species and identity
• Specimen and extraction record
• Plate map and assay lot
• Controls, interpretation and report review

Technical questions from operators

Does 16 positions mean 16 birds per run?

Controls, replicates and repeats also occupy positions. Calculate capacity from the actual layout.

Can one assay be assumed to cover all parrots?

Establish species coverage through the assay documentation and validation.

Use the required controls and the method settings for each sample group, and preserve the original observations alongside the accepted result and review action.
