Retention and effectiveness of a single application of an adhesive sealant in preventing occlusal caries: final report after five years of a study in Kalispell, Montana.

The single application of a BIS-GMA adhesive sealant in Kalispell on a paired half-moouth basis and the annual monitoring of the sealed sites for five years is not a recommended preventive regimen. The study does proved information on the potential long-term in vivo retention of the sealant and its ability to prevent dental caries. The findings of this study clearly show that when this pit and fissure sealant is retained, its is effective in preventing caries in sealed tooth surfaces. Moreover, on occlusal surfaces, the usual susceptibility to decay is not altered by having been treated with a sealant that is not retained.

Influence of energy or protein supplementation during midpregnancy on forage intake of ewes grazing Montana winter range.

A 2-yr winter experiment was conducted to determine the influence of either energy or protein supplementation during midpregnancy on fecal output (FO), forage intake, blood metabolite profiles, and BW changes of ewes grazing winter range. Thirty-two Targhee ewes were selected for uniformity in age and BW and assigned randomly to one of four dietary treatments 1) no supplement (NONE); 2) 150 g of barley supplement (BAR); 3) 75 of feather g meal, blood supplement (FM/BM); and 4) 75 g of FM, BM, urea supplement (FM/BU/U). Two 5-d experimental periods were conducted during each winter (January and February). Forage FO (P = 0.9), total FO (P = 0.7), and subsequent forage intake (P < .01) were higher during Yr 1 than during Yr 2. Supplement type did not affect forage DMI when expressed either as grams/day (P = .57) or as a percentage of BW (P = .52). Body weight changes and body condition scores were not affected (P > .10) by year but were affected (P < .01) by treatment; unsupplemented ewes lost more (P < .01) BW and body condition than supplemented ewes. Serum urea N (SUN) concentrations were affected (P < .03) by a year x treatment interaction. Unsupplemented, FM/ BM, and FM/BM/U ewes had higher (P < .10) SUN concentrations during Yr 1 than during Yr 2, averaging 9.8 ml/dL and 7.5 mg/dL, respectively. Barley-supplemented ewes had similar (P > .10) SUN concentrations both years, averaging 7.4 mg/dL. Alternate-day supplementation during midpregnancy with energy of protein had no effect on forage DMI of ewes grazing winter range.

Survey of free-ranging elk from Wyoming and Montana for selected pathogens.

From December 1991 through January 1995, a disease survey was conducted on herds of free-ranging, hunter-killed elk (Cervus elaphus nelsoni) from three areas in proximity to Yellowstone National Park (YNP), Wyoming (USA), after tuberculosis caused by Mycobacterium bovis was discovered in a captive herd of elk in the area. Complete or partial sets of specimens from 289 elk collected between December 1991 and January 1993 were examined histologically; no mycobacterial lesions were observed. Lesions of tuberculosis were not detected in tonsils or lymph nodes of the head from an additional 99 hunter-killed, adult elk from one area (area 2) collected in January 1995. Neither M. bovis nor M. paratuberculosis were isolated from any of the specimens cultured. Antibodies to Brucella abortus were detected in serum samples from 0%, 1%, and 1% of elk from three areas sampled (areas 1, 2 and 3), respectively. Brucella abortus biovar 1 was isolated from multiple tissues from one seropositive animal from area 3. Larvae with morphology consistent with Dictyocaulus sp. were found in 12%, 14%, and 0% of fecal specimens tested from areas 1, 2, and 3, respectively. Pasteurella multocida and Actinomyces pyogenes were isolated from a lung with purulent bronchopneumonia and abscesses.
