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
What is BOARBETTER™?
• 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)
BOARBETTER™ FIELD TRIAL SUPPORTING DATA
• 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
