This thesis concerns an investigation of the ability of sheep to withstand cold. It includes studies of the initial cold resistance, the ability to acclimatize to cold, and of the variation within and between breeds of sheep. The cold resistance of shorn Scottish Blackface, Southdown and Welsh Mountain sheep, equal numbers on high or maintenance levels of nutrition, was measured by the rate of ...

The effects of essential oils isolated from Douglas fir needles on sheep and deer rumen microbial activity were tested by use of an anaerobic manometric technique. Rumen microorganisms were obtained from a sheep which had been fed mainly on alfalfa hay and dried range grass. One deer used in this study had access to Douglas fir trees the year around, whereas the other deer had no access to Doug...

BACKGROUND The variability in the clinical or pathological presentation of transmissible spongiform encephalopathies (TSEs) in sheep, such as scrapie and bovine spongiform encephalopathy (BSE), has been attributed to prion protein genotype, strain, breed, clinical duration, dose, route and type of inoculum and the age at infection. The study aimed to describe the clinical signs in sheep infecte...

This study aimed to establish whether sheep flock production losses due to nematode (worm) infections are typically greater in mature sheep selected for anthelmintic treatment at random compared to sheep selected for treatment based on low (poorer) body condition score (BCS). The study also examined the proportion of sheep in flocks that could be left untreated before production losses became e...

The sero-surveillance and immunization studies on Peste des Petits Ruminants (PPR) in non-descriptive indigenous sheep and Black Bengal goats aged between 5 to 12 months were carried out in the district of Mymensingh during the period from June to November 2003. Sero-prevalence of PPR by using competitive enzyme linked immunosorbent assay (C-ELISA) was conducted on 100 sheep and 100 goats which...

Field, Miller, and Russell (1962) reported that sheep in Iceland injected intracerebrally by Dr. Palsson with a suspension of the brain of an acute case (SELL) of multiple sclerosis developed a disease histologically indistinguishable from scrapie. In the following year, Campbell, Norman, and Sandry (1963) noted that Dr. Palsson had again elicited a scrapie-like disease in sheep injected intrac...

The Nordic and Baltic countries and North-western Russia have >20 old native sheep breeds. These together with recently synthesized breeds and local populations of international breeds make up the northern European sheep diversity. Changes in agriculture threaten to erode genetic diversity in sheep. Molecular genetic variation was assessed to understand genetic diversity in northern European sh...

I. The relationship between the heart rate and the energy expenditure of four sheep, S, S,, S, and S1, was studied under conditions known to increase energy metabolism. 2. A close relationship between heart rate and energy expenditure was shown to exist in three of the four sheep tested when energy expenditure was increased by cold exposure and by increased levels of food intake. 3. The source ...

Shiga toxin producing Escherichia coli have been associated with HUS, HC and TTP in human. We found recto-anal mucosal sample in sheep as well in cattle is the main site for E. coli O157 localization. 1246 E. coli isolates from 872 both healthy and diarrheic animals were analyzed, by screening for the presence of Shiga toxin-producing (VT 1 and VT 2) and intimin (eae) genes used Multiplex PCR. ...
