Using old newspaper as feed for cattle and sheep

Introduction: Larry Berger, a professor of animal nutrition at the University of Illinois in the United States, has developed a way to make use of old newspapers as cattle and sheep drinks, which is an abandoned newspaper from the United States In old newspapers, although there are almost no vitamins and minerals, they are rich in cellulose These cellulose are tightly bound glucose molecules with long chains, which can not be directly used and digested by ruminants such as cattle and sheep For this reason, Professor Larry Berg first cut the newspaper into pieces, added water and 2% hydrochloric acid; then put it into a pot, and boil it for two hours, so that under the action of acid and high temperature, the old newspaper will break down cellulose, so that ruminant animals such as cattle and sheep can eat and digest it In the experiment, Professor Larry Berg added 20% - 40% of high temperature alfalfa feed commonly used by cattle and sheep The acidified old newspaper, as a result, will not affect the growth and development of cattle and sheep However, when using newspapers as cattle and sheep feed, it should be noted that their newspapers must be printed with ink based on soybean oil Because this kind of ink is harmless to human body and livestock According to Professor lalieberg, there are more than 30 million cattle in the United States If 20% of the high-temperature acidified old newspapers can be added to the drinks of cattle, the recycled old newspapers in the country can be digested In this way, not only a large amount of cattle feed can be saved, but also the waste newspapers can be reused (author:) share to feed Weibo share to:
