Our SGL sires are selectively bred to shorten your calving period, making them ideal for late-calving cows. You’ll benefit from more days in milk, while your cows experience a longer recovery time.
It all adds up to an improved bottom line.
Benefits of SGL semen
Compact calving
SGL semen can get calves on the ground 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.
A longer recovery time can also:
- reduce interventions
- improve AI conception rates
- lower empty rates
- improve body condition.
Increase days in milk
SGL sires can help shorten your herd’s calving spread, giving you more days in milk and in-turn boosting your farm’s income.
Alternative to natural mating bulls
Using SGL bulls provides a cost-effective and convenient alternative to using natural mating bulls, while protecting your livestock and property. It also reduces biosecurity risks, enhances health and safety, and minimises the risks associated with bull fertility and fatigue.
Understanding gestation length
All our sires have a gestation length breeding value (BV).
It’s expressed in days. A negative number means a shorter-than-average gestation length.
Bulls pass on half their gestation length BV to their offspring. For example, if a bull’s BV is -20 his calves are likely to be born 10 days early.
SGL products
SGL CompactTM
With SGL Compact sires you can shorten gestation length by up to 12 days. They are selectively bred to shorten gestation length only so offspring must not be bred. Mate them over your late-calving cows to bring them back in-line with the rest of the herd.
SGL Hereford
LIC and leading NZ Hereford breeders, Shrimpton’s Hill Herefords, have developed easy-calving and easy-to-identify Hereford sires can reduce gestation length. This means Australian farmers have more valuable calves to offer the beef industry and you save valuable time identifying calves.
SGL + BW
Our SGL + Breeding Worth (BW) bulls are a win-win. They give you shorter gestation as well as sound genetic merit for heifer calf replacements. These sires have been rigorously tested to ensure their traits are passed on to their offspring, to improve the genetic value of your herd.
