Getting cows in calf
…is key for a dairy farmer’s profitability. That’s why at Alta we always advise to select for high semen fertility bulls. However with Spring joining in full swing, it actually makes it even more important to select for fertility to give your return cows the best chance to get in calf. Getting your in-calf rate to 85% in the first 6 weeks should be your target because it translates to more profit in your pocket.
Concept Plus is the industry leading Sire Conception ranking. Concept Plus has a more robust and accurate semen classification system than any other North American semen fertility rating and is the “go to” ranking for many progressive farmers globally. A sire designated Concept Plus will deliver 2-5% higher conception rates than the average. So by using Concept Plus semen you will give your cows every chance to get pregnant!
Additional to getting your returns in calf, condensing their calving period is possible by selecting for short gestation length sires. This will enable you to better manage the calving period and have more cows returning to milk faster meaning more profit.
SGL is the trait for the expression of gestation length in the US. This figure is expressed in expected days shorter (-) or longer compared to the average of 277 days for Holstein sires. Short gestation length sires, or those with a negative value, will provide a shorter gestation period and can be used to reduce your overall calving period.
To maximise profit at joining for return cows use Concept Plus rated sires who also have a shorter gestation length.
