Bauman presented his research findings Wednesday at the 1984 Cornell Nutrition Conference for Feed Manufacturers now in BUTLER AGRI-BUILDER session in Syracuse. The Cornell scientist conducted the study jointly with two Danish scientists-Kris Sejrsen and John Foldager-at the Danish National Institute of Animal Science in Copenhagen during 1983-84. The study had two objectives: to deter mine effects of long term administration of natural bovine growth hormone on growth rates and mammary development of young growing dairy animals. Nine pairs of identical twins were tested in this study. One of each pair received daily in jections of hormone for more than 100 days, and the other one of each pair was used as con trol. The hormone treat ment began shortly before the test animals reached puberty (about £ months old); each weighed about 400 pounds (180 kilograms). Results show that the hormone treatment improved weight gain at a rate of about 9 percent a day during the study, with more muscle and significantly less fat. Because fat production in the animals tested is significantly lower than normal, the finding may have a major impact on the beef industry in the United States. “The difference between the value of fat, a by-product, and feed costs for the fat represents an annual cost of more than $1 billion dollars that is absorbed by the producer, processor, and consumer,’’ Bauman pointed out. “Thus, even small shifts in diverting nutrients for muscle rather than body fat would have tremendous com mercial impact.” In another phase of the Cornell-Denmark study, researchers discovered that the mammary tissue called “parenchyma” that manufactures milk in cows’ mammary glands was increased by 38 percent. “This is a dramatic boost,” Bauman commented. He said that it is theoretically possible for these animals with greater milk-producing tissue to produce more milk than normal cows when they go into milk production. “Results from this initial experiment are extremely encouraging, but additional studies are needed to determine if this enhanced mammary development around puberty will lead to increased milk yields,” Bauman said. As in other studies in which hormone-treated milking cows increased their milk yields dramatically (up to 41 percent), Bauman is convinced that results of the Cornell-Denmark study strengthen graving evidence that (Turn to Page A 33)
