First, a breakthrough in twin breeding technology
In the past, the traditional method of producing twins involved using a scalpel to split fertilized eggs. However, this approach often led to damage because the transparent membrane surrounding the egg is highly elastic and delicate. Recently, researchers at Japan's Tohoku Agricultural Experimentation Field have developed a more precise technique. Instead of cutting the membrane directly, they create a tiny hole, about 30 micrometers in diameter, on the membrane. As the egg divides, the membrane naturally protrudes through the hole, forming a droplet-like shape. When the cells that grow out of the hole reach half the size of the original egg, a second embryo can be carefully separated from the droplet. This method has significantly improved the success rate of twin production, increasing it from the previous 10-20% to as high as 50%.
Second, fatty acid calcium boosts milk yield in dairy cows
A study conducted by the Ho Chi Minh Feeding Institute in Hokkaido, Japan, found that adding calcium fatty acids to the diet of dairy cows can enhance milk production. In their experiments, they included 2.2% fatty acid calcium in the feed of 12 different groups of cattle. After a 105-day feeding period, the average daily milk output for each test group was 7.5 kg higher than that of the control group. This suggests that fatty acid calcium is not only effective but also a cost-efficient additive for improving dairy cow performance. The results highlight its potential as a valuable tool for farmers aiming to increase productivity while maintaining economic viability.
