17:00  Genetic lag

Genetic lag refers to the delay in genetic improvement reaching commercial populations compared to the rate of genetic improvement in elite breeding populations. This means that while elite breeders are making rapid genetic progress, it takes time for those advancements to be fully realized in the animals that farmers and consumers ultimately use. According to Genesus Genetics, this lag can be substantial and is influenced by factors like generation intervals and how quickly genetics are transferred from the nucleus to the commercial level.  

Here's a more detailed explanation: 

Elite Nucleus vs. Commercial Herds:

Breeding programs often have a nucleus herd, which is where elite animals are bred and selected for desirable traits. These animals are then used to produce breeding stock for multiplier herds, which in turn produce animals for commercial production. 

The Transfer Process:

The genetic improvement generated in the nucleus is meant to be transferred down through these tiers. However, the rate of transfer is not always immediate. 

Factors Influencing Lag:

Several factors contribute to genetic lag: 

Generation Intervals: The time it takes for an animal to reach breeding age impacts how quickly genetic progress can be transferred.  

Transfer Methods: The methods used to disseminate genetics, such as artificial insemination (AI) or natural mating, can affect the speed of transfer.  

Number of Breeding Cycles: Each breeding cycle in the transfer process adds to the lag. For example, in swine, genetic lag is calculated based on the number of parity cycles in the commercial herd, according to ScienceDirect.  

Consequences of Lag:

Genetic lag can mean that commercial herds are not realizing the full potential of the genetic improvements being made in the nucleus.  

Reducing Genetic Lag:

Strategies to reduce genetic lag include: 

Genomic Testing: Using genomic information to identify animals with desirable traits can help speed up selection and reduce the lag.  

Optimizing Transfer Methods: Improving the efficiency of transferring genetics from the nucleus to commercial herds can also reduce the lag, according to Genesus Genetics.  

Understanding Life History Traits: For wild populations, understanding traits like generation time and life span can help predict and manage genetic lag, particularly in the context of conservation, according to ScienceDirect.
