Scientists have increased the possibility of successful twinning through extensive genetic research. They now also able to inform the producer of twins through the use of proper palpation techniques as well as ultrasound. Blood can be analyzed in labs to determine fetal weight gain. In addition nutritious feeds and technology that aids in calf survival have made the possibility of Winslow 3 high twinning success rates closer to being reality. Results from twinning are very appealing to a farmer who can use one brood cow to produce two calves per year.
Reports show that beef cattle can wean a higher total weight per cow.
Over time, however, the twin calves approach the weight of the single calves. Despite this seemingly large difference in weaning weights, it should be realized that there are two calves to sell from a set of twins as compares to one from a single birth. In addition to their size, twin calves consume less rations of fees than their counterparts. Despite all of these draw backs, work is being done to help twinning become profitable, instead of problem causing. A gene has been researched that causes twinning in cows.
