Abstract

Two |Beta~-adrenoceptor agonists, clenbuterol and ketoclenbuterol, were examined for their effects on growth and cardiac tissue. In female rats, clenbuterol caused a 48% increase in weight gain (P |is less than~ .05), with improved feed efficiency (26%; P |is less than~ .1) and increased muscle mass (9%; P |is less than~ .1). Ketoclenbuterol had less effect on weight gain (30%) and feed efficiency (16%) and did not increase muscle mass. Next we studied the adverse cardiovascular effects of these compounds. Neither drug increased the force of contraction of isolated rat ventricular papillary muscle. Clenbuterol was potent at causing an increase in the rate of contraction of isolated rat atria, and when fed to cattle over 2 d, the drug caused heart rate to increase by 92 to 117%. In contrast, ketoclenbuterol was not a potent stimulator of atrial rate in the rat, and in cattle it caused a smaller increase in heart rate than clenbuterol (12 to 27%). Finally, cattle that were underfed to simulate dry-season tropical pasture conditions were treated with clenbuterol or ketoclenbuterol for 35 d. Ketoclenbuterol caused no beneficial changes in N metabolism. The results obtained with clenbuterol were equivocal, and might have been confounded partly by the refusal of some treated animals to eat all the feed offered. Although clenbuterol did not cause a reduction in total urinary N output relative to control animals, marked reductions in plasma urea concentrations and in urea synthesis were observed (23 to 53%; P |is less than~ .001). We conclude that ketoclenbuterol is not effective for attenuation of dry-season protein loss in cattle. Clenbuterol seems to be less effective in underfed cattle than in well-fed cattle, and further evidence is required to judge whether compounds of this nature are likely to benefit tropical cattle under harsh grazing conditions.

Spacecraft Instrumentation
Abstract

The Moderate Resolution Imaging Spectrometer (MODIS) is a facility instrument to be flown on the first Earth Observing System (scheduled launch in the late 1990s). The MODIS has two components. One component is a 110-deg-scan-angle instrument called MODIS-N (nadir). This instrument has 40 selected bands supporting observations of the land surface, the oceans, and atmosphere in the visible, NIR, short-wave IR (1.0-3.0 microns), and thermal IR (3.0-15.0 microns). The other component is a 90-deg-scan-angle scanning instrument that can tilt fore and aft along the satellite track, called MODIS-T (tilt). Both MODIS-N and MODIS-T are nearing the end of detailed design studies. The driving scientific requirements include absolute calibration accuracy 2 percent, instrument-induced polarization less than 2 percent, SNR reaching 800:1 for observing ocean color at large solar zenith angles, and dynamic range allowing observations of cloud characteristics and snow-covered areas.

8. Measuring Mirror Tilt With High Accuracy

Author

Magner, T. J

Subjects
Mechanics
Abstract

Stroboscopic technique freezes mirror motion so displacements can be measured. Improved autocollimator accurately measures angular tilt of plane mirrors in rotational or reciprocating motion. Device is conventional autocollimator in which steady light source is replaced by stroboscope synchronized with mirror motion. It is accurate to 1 second of arc.

33. Sustained growth promotion of steers, using anabolic steroids

Author

Hunter, R. A., Magner, T., and Berger, K. T.

Abstract

This experiment tested the hypothesis that sustained growth promotion of steers could be achieved by alternate use of oestrogenic and androgenic anabolic steroids. Twenty-one high grade Brahman (Bos indicus) steers were divided into 3 groups of 7 and allocated to 1 of the following treatments: control; implantation in the ear with 45 mg oestradiol-17β for approximately 100 days followed by treatment with testosterone propionate (this rotation occurred twice); implantation with 45 mg oestradiol-17β at approximately 100-day intervals. Steers were housed in individual pens in an animal house and fed a restricted diet to regulate their growth rate to about 0·6 kg/day over a 58-week period. At intervals during the first 30 weeks, steers were transferred to metabolism crates and their nitrogen retentions measured. At the end of the experiment the steers were slaughtered and their carcass characteristics determined. The mean growth rates of the steers treated with 2 steroids alternately (0·75±0·06 kg/day) and of steers treated continuously with oestradiol-17β (0·72±0·06 kg/day) were significantly (P = 0·01) higher than that of control steers (0·62±0·10 kg/day). Treatment with oestradiol-17β during the first implant period was associated with higher (P < 0·05) nitrogen retentions in the first weeks after implantation with attenuation of the advantage at the end of the 100-day period. At slaughter, steers from both steroid treatment strategies were almost 60 kg heavier (P < 0·05) than the controls, with carcasses about 30 kg heavier. Steers treated continuously with oestradiol-17β had significantly (P < 0·05) thicker subcutaneous fat cover at the P8 rump site (19·4 mm) than the controls (12·4 mm) or those treated during the final period with testosterone propionate (12·3 mm). It was concluded that sustained growth promotion of steers using anabolic steroids can be achieved. cattle, protein deposition.

Abstract

A major locus conferring resistance to the causal organism of powdery mildew, Erysiphe polygoni DC, in mungbean (Vigna radiata L. Wilczek) was identified using QTL analysis with a population of 147 recombinant inbred individuals. The population was derived from a cross between 'Berken', a highly susceptible variety, and ATF 3640, a highly resistant line. To test for response to powdery mildew, F7 and F8 lines were inoculated by dispersing decaying mungbean leaves with residual conidia of E. polygoni amongst the young plants to create an artificial epidemic and assayed in a glasshouse facility. To generate a linkage map, 322 RFLP clones were tested against the two parents and 51 of these were selected to screen the mapping population. The 51 probes generated 52 mapped loci, which were used to construct a linkage map spanning 350 cM of the mungbean genome over 10 linkage groups. Using these markers, a single locus was identified that explained up to a maximum of 86% of the total variation in the resistance response to the pathogen.

Abstract

Brahman steers (Bos indicus) were treated with the alpha 2-adrenergic agonists, guanfacin.HCl (4-440 micrograms/kg), UK14304.HCl (20-125 micrograms/kg) and clonidine.HCl (0.2-5 micrograms/kg). All three agonists produced dose-dependent reductions in metabolic rate, heart rate and rectal temperature (P < 0.001). Brahman heifers were infused with idazoxan.HCl (10 micrograms/kg/hr), an alpha 2-adrenergic antagonist, alone and in combination with an intramuscular injection of guanfacin.HCl (80 micrograms/kg). Idazoxan alone did not alter rectal temperature but it blocked the guanfacin-induced lowering of rectal temperature (P = 0.05 for the interaction between the two drugs). Idazoxan alone raised metabolic rate (P = 0.01). Guanfacin lowered metabolic rate (P = 0.007) and heart rate (P = 0.03), but the blocking of the guanfacin effect by idazoxan could not be demonstrated (P > 0.05) for either. The same heifers treated with 0.5, 1.0 and 5 micrograms/kg prazosin.HCl, an alpha 1-adrenergic antagonist, had significant changes in metabolic rate (P = 0.003) and heart rate (P = 0.008) at 0.5 and 5 micrograms/kg. Metabolic rate and heart rate decreased at the lower dose and increased at the higher dose. These results with cattle parallel previous results in rats (Gazzola, 1993) where a minimal, conceptual model for the partial control of resting metabolic rate by the sympathetic nervous system was postulated. The model indicates points of control in the sympathetic nervous system which could be manipulated so as to alter the metabolic rate of farm animals.
