Programmable Lighting System for Swine Breeding Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The swine breeding industry faces challenges with low success rates of artificial insemination due to variable ovulation times in female swine, reduced fertility during summer months, and variability in boar semen quality and concentration, leading to high costs and inefficiencies.
Innovation Solution
A programmable LED lighting system that simulates changing light periods to mimic seasonal changes, using a combination of white and red light to enhance breeding probabilities by cueing swine into a winter-like photoperiod, thereby increasing fertility and sperm motility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If artificial insemination is used to improve breeding efficiency and control mating, then breeding record accuracy and sperm selection capability are improved, but the cost of breeding increases and success rate remains low due to variable ovulation times and seasonal fertility changes
Solution Approach 1:
The patent applies parameter changes by modifying the photoperiod (light-dark cycle duration) and light intensity parameters to simulate seasonal changes. This triggers physiological responses in swine that synchronize ovulation timing and improve conception rates, directly addressing the reliability issue while maintaining the productivity benefits of artificial insemination
2Reliability
If constant monitoring of female swine is performed to track ovulation times, then conception success rate is improved, but labor costs and time consumption increase
Solution Approach 1:
The lighting system performs preliminary action by pre-synchronizing ovulation times through controlled photoperiod exposure before artificial insemination occurs. This allows breeders to predict optimal insemination windows in advance, eliminating the need for constant monitoring while maintaining high conception success rates
3Reliability
If high performance boar semen is used to improve conception rates, then breeding success is improved, but the cost of semen and breeding operations increases significantly
Solution Approach 1:
The lighting system enables self-service by allowing standard-quality boar semen to achieve high conception rates through photoperiod-induced synchronization of female receptivity. This eliminates the need to purchase expensive high-performance semen, as the lighting system itself provides the enhancement needed for successful breeding
4Productivity
If swine are bred during summer months when fertility is naturally reduced, then breeding continuity is maintained, but conception success rate decreases
Solution Approach 1:
The lighting system applies periodic action by implementing cyclic variations in photoperiod duration that mimic natural seasonal transitions. This periodic manipulation of light exposure triggers physiological changes that restore high conception rates during summer months while maintaining breeding continuity throughout the year

AI summary
A method of increasing the probability of breeding swine via a lighting system with a programmable timing device. The lighting system is programmed to present differing photoperiods such that the amount of light observed by a swine every day or week gradually decreases, mimicking a seasonal change, typically from summer to fall. As a result, swine psychologically and physiologically believe that seasons are changing resulting in increased probability of breeding for the swine.
