Researchers of the animal husbandry institute under the Academy of Agricultural Science measure the nutritive value of high-yielding fodder crops.
“Our institute has pushed scientific breeding and introduction of high-yield varieties and feeding as a priority research project,” said Ok Jin Yong, director of the animal husbandry institute of the Academy of Agricultural Science.
According to him, the institute has made successes in increasing the number of Korean cattle with superior characters.
Scientists developed a technology of nearly doubling the activity of cattle’s deep frozen semen as against previously and produced deep frozen semen of the highbred Korean cattle to send it to the livestock farming base in the Sepho area and others across the country. They improve the rate of impregnation by transferring embryo.
In addition, they improved the goat of native strain, thus breeding a new variety of goat whose annual milk output is over two times and establishing the breeding system of good strains of pig, goat and rabbit whose body weight is heavy in a short time.
Based on it, the institute set up the image data transmission system with relevant pastures and stock-farms to have a correct understanding of problems in time and give appropriate technical guidance and assistance.
Research is also carried on steadily to reduce unit feed by solving the problems of protein feed and feed additive.
In this course, they developed a technology conducive to widely spreading high-yield and nutritious Aeguk grass.
After years of research, the institute ensured that the storage life of the seed stems of Aeguk grass becomes about 100 days and that of its seed roots over 150 days. And it found out a cultivation technology for increasing per-hectare yield and its processing method.
It also contributed to increasing milk and meat output by over 10 percent while reducing the consumption of feed by developing mineral wafered feed and additives. And its new method of eliminating toxicity and using cottonseed cake based on a microbiological method helped save 30-50 percent of soybean cake while providing a guarantee for increasing livestock products.
The research findings developed by them have been applied to the Unjong Stockbreeding Cooperative Farm and other units.
