Short Gestation

Short Gestation Length semen from LIC

With bulls selectively bred to shorten gestation length up to 10 days, your cows get more time to recover before mating, more chance of getting back in calf and more days in milk.

SGL can get calves on the ground up to 10 day earlier than normal gestation length bulls. This is an effect way to compact your calving period and bring your late calving cows forward. 

Cows that calve early in a herd’s calving period have more time to recover and cycle before mating season. This increases their chances of getting back in calf to Artificial Breeding and reduces empty rates.

When your herd’s calving spread is compacted, you can benefit from more days in milk. SGL can give you up to 10 more days in milk and if there is one thing every dairy farmer needs, it’s milk.

Extending your AB programme with SGL gives you the option to eliminate or reduce the costs and risks involved in using natural mating bulls. 

SGL Dairy

SGL Dairy is used only for accomplishing short calving intervals; it is not effective or authorised for breeding replacement heifers. SGL Dairy is a team of bulls with a gestation length up to -20 days. When mated to a cow with normal gestation length, these bulls can reward you with a calving interval up to 10 days shorter than normal – that’s 10 days extra milk in your vat and 10 days extra profit in your pocket.

SGL Hereford

LIC, in alliance with leading Hereford breeders, Shrimpton’s Hill Herefords, have developed easy-calving and easily identifiable Hereford sires that reduce gestation length by an average of 3 days. This means you have more valuable calves to offer the beef industry and you save valuable time identifying calves.  


Presenting genetics for shorter gestation as well as sound genetic merit for heifer calf replacements, SGL + BW bulls are a win-win. These SGL sires have been rigorously tested to ensure their traits are passed on to their offspring, with the purpose of improving the overall efficiency of your herd.
