Bioinformatics in Meat ScienceCase Study

Group 2 Brandy Eves & Britney Faris

Male and female pig meat have a different

smell

Joe is paying extra money to have only Gilt

meat

His last batch may have Boar in it

Joe wants Sue to develop a quick, easy,

reliable test for evidence of Boar meat

mixed into his Gilt meat

GILT : A gilt is a young female pig that has not given birth to a litter of her own.

SOW : A sow is an adult female pig that has given birth to one or more litters of piglets.

BARROW : A barrow is a male pig that has been castrated or is incapable of reproducing before he reaches sexual maturity.

BOAR : A Boar is an uncastrated domestic or wild male pig.

Two naturally occurring compounds:

androstenone and skatole.

Odor compared to urine and feces

Occurs in boars if not castrated.

Compounds can be detected by taste and

smell when the meat is heated.

Only on the Y chromosome

Tells the embryo to be a boy

Is mapped out

It’s a protein

Taq polymerase

Primers

Temperature cycling

An enzyme

It’s actually a bacteria

Thermus aquaticus live in hot springs

It is used because it can withstand the

higher temperatures that PCR tests use

Strand of nucleic acid

Starts the sequence

Must match the DNA sequence

Must withstand high temps

Changes in temps breakdown & build DNA

Find the Y Chromosome

The Y chromosome can be found using a SRY test

Joe can test for boar easily in any

meat sampling and in any stage of

processing.
