The Benefits of Using Pheromones in Swine Production

What is a pheromone?

• Pheromones are molecule(s) that are produced by one animal that change the physiology or behavior of another animal of the same species
• Pheromones are sensed at very low concentrations and can have powerful effects
• Pheromones and their receptors are conserved among many species and therefore are natural and common in nature
• We know that in the pig, the male sex pheromone is composed of a combination of three separate molecules

How do pheromones work?

• Pheromones bind to specific olfactory receptors
• The male sex pheromone naturally activates GnRH in the hypothalamus which causes LH pulses and ovulation
• The male sex pheromone quickly changes sow behavior


BOARBETTER™ is a natural pheromone that contains Boar Saliva Analog (BSA™)
• BSA™ is the patented triple boar saliva pheromone that is a combination of three molecules (Androstenone, Androstenol and Quinoline)



Works through olfactory therapy
Non invasive treatment

Proven in field studies to be effective

Can reduce labor costs

Safe for use around people and livestock

Brings higher profits to producer


Market Need
• Improved breeding herd productivity
• Worker safety issues with “teaser” boars
• Teaser boars are dangerous and costly to maintain
•Current single pheromone products have variable results


Improve Sow Productivity
• Improves total born and born alive
• Identifies sows in standing heat
• Can reduce labor needs in the breeding barn
• Improves pigs weaned per batch when used correctly

How to Use

• Begin administering BOARBETTER post weaning on day 4 (recommended). Earlier application may reduce the wean-to-estrus interval
• Apply as supplied. Do not dilute
• Calibrate a garden type or other sprayer to deliver the correct dose
• Spray 4 mL of BOARBETTER onto the female’s snout (directing towards the nostrils) prior to heat check
• Use just prior to normal boar exposure
• Apply back pressure test to check for signs of estrus
• If using conventional artificial insemination breed the femaleif she is in standing heat
• If using PCAI (post cervical artificial insemination) follow farm specific PCAI breeding protocols
• An additional spray can be administered to females while breeding occurs during conventional artificial insemination but after breeding occurs when using PCAI
• If sow is not in estrus, repeat treatment daily until estrus occurs
