Genomic testing of cattle, also known as DNA testing or genotyping, is a process used to analyse the genetic makeup of individual animals. This technology allows farmers to better understand the genetic traits present in cattle, such as disease resistance, meat quality, and fertility characteristics.

1. Sample Collection: The process starts with collecting a sample of DNA from the animal. This can be done using various methods, such as collecting hair follicles with roots intact, blood samples, ear tissue samples, or semen. Tissue samples are preferred as they are more robust and easily stored. These are collected in a TSU (tissue sampling unit).

2. DNA Extraction: Once the sample is collected, the DNA needs to be extracted from it. This is typically done in a laboratory setting using specialised kits and protocols designed to isolate DNA from the sample material. The extracted DNA is purified to remove any contaminants that could interfere with subsequent testing.

3. Genomic Profiling: The extracted DNA is then analysed to obtain a genomic profile of the animal. This involves genotyping specific genetic markers or regions of interest across the animal's genome. These markers are chosen based on their known associations with traits of interest. High-throughput genotyping technologies, such as microarray-based SNP (single nucleotide polymorphism) arrays, are commonly used for this purpose.

4. Data Analysis: Once the genotyping is complete, the resulting data is analysed to identify the specific genetic variants present in the animal's genome. This analysis may involve comparing the animal's genotype to reference genomes or databases of known genetic variants associated with particular traits. Statistical methods and bioinformatics tools are used to interpret the data and identify genetic markers that are linked to desirable traits.

5. Trait Prediction: Based on the genetic markers identified through genomic testing, breeders can make predictions about the animal's phenotype, or observable traits. These predictions can inform breeding decisions, such as selecting animals with the most desirable genetic traits for breeding purposes. However, it's important to note that while genomic testing provides valuable insights into the genetic potential of an animal, other factors such as environmental conditions can also influence its actual phenotype.

The RePRO BI bundle gives producers genomic breeding values (GBVs) on seven traits including: age of puberty, ability to rebreed, height, weight, body condition score, tick and fly lesions and temperament. The bundle also includes Poll/Horn and breed composition.

This allows you to identify high and low performing animals within your breeding herd.
