The conversion of propionyl coenzyme A to succinyl-CoA involves carboxylation to methylmalonyl-Cob (a), isomerization of methyhnalonyECoA (a) to its enantiomorph methyhnalonylCoA (b), and isomerization of the latter to succinyl-CoA (3). Since methylmalonyl-CoA (a) has recently been shown to have the D configuration (4, 5), the reversible reaction catalyzed by methylmalonyl-CoA racemase will hen...

An outbreak of subclinical mastitis in a flock of 620 milking sheep was investigated. Microbiological and epidemiological analyses identified the causative agent as belonging to the Burkholderia cepacia complex (formerly Pseudomonas cepacia). Every ewe in the milking flock was individually tested for subclinical mastitis on two separate occasions, 6 weeks apart, by the California (rapid) mastit...

A simple analytical procedure derived from that described by Zinn and Owens (1980), based on the determination of nucleic purine bases (RNA eq), was carried out to measure microbial nitrogen flow in the ruminant duodenum. Several procedures for sample preservation were tested; the efficiency of each step of the analytical method was also determined using high performance liquid chromatography (...

The use of broiler litter as an emergency feed during droughts and other periods of feed shortages was evaluated in terms of its effect on the health of sheep. Pure broiler litter (i.e. excreta plus wood shavings), and litter mixed with 7.5 or 15% molasses were fed for 83 days to 2-year-old wethers. The addition of molasses to the litter caused a significant increase (p < 0.01) in feed intake a...

A study was implemented to investigate the presence of contagious caprine pleuropneumonia (CCPP) in East Turkey. This study was based on clinical surveillance in the field, surveillance at regional slaughterhouses and regular submission of suspected lesions to regional laboratories. The results showed that the agent of CCPP, Mycoplasma capricolum subspecies capripneumoniae (Mccp), could be dete...

With climate change bound to affect food and feed production, emphasis will shift resilient adapted indigenous livestock sustain animal production. However, comprise several varieties, strains ecotypes whose genomes are poorly characterized. Here, we investigated genomic variation in an African thin-tailed Desert Sheep sampled Sudan, using 600K genotype data generated from 92 individuals repres...

Introduced infectious diseases pose a significant threat to wildlife populations and are exceptional conservation challenges, in part because they can precipitate much more rapid and devastating population declines than habitat encroachment. Pneumonia epizootics have played a major role in the dynamics and conservation challenges of bighorn sheep (Ovis canadensis) populations. A large proportio...

Long-term livestock grazing has shaped landscapes, biodiversity, societies, cultures, and economies in the North Atlantic over time. However, overgrazing become a major environmental sustainability challenge for this region, covering Faroe Islands, Greenland, Iceland, Norway, Scotland. The objective of study was to elicit narratives spatial patterns local people’s management preferences sheep I...

Sheep pox and enterotoxemia are important diseases of sheep, and these diseases cause severe economic losses to sheep farmers. The present study was undertaken to evaluate the potential of formaldehyde-inactivated recombinant epsilon toxin as a vaccine candidate. The potency of the recombinant epsilon toxoid with aluminum hydroxide as an adjuvant in sheep was determined. Vaccinated sheep were p...
