Short Gestation Length

Get more with LIC's short gestation length (SGL) bulls.

With bulls selectively bred to shorten gestation length, you can shorten your calving period, give your late-calving cows more chance of getting back in-calf and increase your days in milk. It all adds up to an improved bottom line.

LIC's short gestation length bulls give you more days in milk

More compact calving

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

More cows in-calf

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 insemination (AI) and reduces empty rates.

More days in milk

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.

More control with AI

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

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.  

LIC SGL Hereford are short gestation and easy calving


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.
