EFFECT OF SOMATOTROPIN (SOMETRIBOVE) ON MILK YIELD AND CALF GAIN IN BEEF COWS J.D. Armstrong, R.W. Harvey, M.H. Poore, T. A. Wise*, D.C. Miller,G. M. Gregory and G. Hartnell** Introduction Milk yield and reproductive fitness of the cow and growth potential of the calf are keys for weaning a healthy, heavy calf from each cow annually. Milk yield accounts for over 60 percent of variation in calf weaning weight. Thus we have been investigating factors that regulate milk yield in the cow. Milk ...

EFFECTIVENESS OF RALGRO GROWTH IMPLANTS AND MELENGESTROL ACETATE IN SUPPRESSING ESTRUS AND PROMOTING WEIGHT GAIN IN GROWING HEIFERS B. C. Allison and R. L. McCraw Introduction Producers have an interest in utilizing heifers in summer grazing programs instead of steers, because they are readily available for purchase at a lower price than steers at the beginning of the grazing season. Many producers, however, have reservations about grazing heifers because of the problems associated with their ...

FOLLICULAR DYNAMICS, ESTRADIOL CONCENTRATIONS, AND ESTRUAL RESPONSES IN CATTLE WITH ESTROUS CYCLES EXTENDED BY VARIOUS DOSES OF PROGESTOGENS S.P. Washburn, R.L. Stanko*, and D.W. Shaw** Introduction Progestogens used to control estrous cycles in cattle have been associated with variable fertility. Recent work at several universities including NCSU has shown that low concentrations of progestogens in the absence of the corpus luteum affected luteinizing hormone concentrations, estradiol concen ...

INSULIN SENSITIVITY AND RESPONSIVENESS IN STEERS FED CONTROL OR RACTOPAMINE-TREATED FEED J.H. Eisemann and D. G. Bristol* Introduction The use of pharmacologic agents or growth promotants is widespread in farm animals. In general, these agents are, or mimic, regulators normally present in an animal. Ractopamine, is an example of a beta- adrenergic agonist. In general, beta-adrenergic agonists partition the nutrient supply to increase muscle growth and decrease fat deposition. Use of exogenous ...

Click on the small thumbnail pictures below to magnify the flies. You'll see enlarged illustrations of fruit flies, Drosophila melanogaster. (In our real exhibit you'd be looking at the actual flies crawling around, looking for food or grooming their wings.) Compare the mutated flies to the normal flies. The fruit flies in this exhibit show just a few of the mutations that occur in natural fruit fly populations. The genetic instructions to build a fruit fly-or any othe ...
