Blood mRNA (messenger ribonucleic acid) marker for selecting residual feed intake of ducks and application of blood mRNA marker
By collecting blood in meat ducks and detecting the expression of HLX, ECM1, CSF3R and ASS1 genes, the problem of low feed utilization rate of meat ducks is solved, and the early selection of ducks with high or low residual feed intake is achieved, which promotes the reduction of breeding process and breeding costs.

AI Technical Summary
Technical Problem
The low feed utilization rate of meat ducks leads to high breeding costs. It is difficult for the existing technology to effectively select ducks with high or low residual feed intake in the early stage, resulting in a slow breeding process.
Method used
By collecting venous blood from ducks in early or mid-stage growth, the expression levels of genes such as HLX, ECM1, CSF3R and ASS1 were quickly identified using qPCR technology to select the remaining feed intake of ducks.
Benefits of technology
It has achieved rapid and accurate early distinction between high or low residual feed intake in ducks, promoted the accelerated improvement of feed utilization rate of meat ducks, reduced production costs, and promoted environmental protection and precise breeding.

Abstract
The invention discloses a blood mRNA marker for selecting residual feed intake of ducks, the blood mRNA marker comprises HLX, ECM1, CSF3R and ASS1, the sequence of the HLX gene is as shown in SEQ ID NO.1, the sequence of the ECM1 gene is as shown in SEQ ID NO.2, the sequence of the CSFSR gene is as shown in SEQ ID NO.3, and the sequence of the ASS1 gene is as shown in SEQ ID NO.4. The invention further discloses a preparation method of the blood mRNA marker. An RNA-Seq technology and a bioinformatics method are utilized, gene expression profiles of high and low residual feed intake blood samples of 22-day and 42-day ducks are compared and analyzed, core genes which are differentially expressed at two day ages and are highly related to residual feed intake are screened out, and the discovery of the differential genes provides a theoretical basis for molecular breeding for increasing the feed utilization rate of meat ducks.
