zinc deficiency in sheep and goats: three field cases.zinc deficiency was diagnosed in 2 flocks of sheep and a herd of goats. alopecia and eating of wool were observed. skin lesions were hyperkeratosis and parakeratosis. abnormal hoof growth and a closed stance with arched back and bowed hindlimbs were seen. anorexia, depression, and foot soreness diminished quickly after zinc supplementation. skin lesions healed and hair and wool growth resumed. a cause for the deficiency could not be established.19846735871

performance of hair breeds and prolific wool breeds of sheep in southern illinois: lamb production of f1 adult ewes.two- and three-year-old f1 crossbred ewes produced from suffolk and targhee dams and sires of the prolific wool breeds of finnsheep, combo-6, and booroola merino and the hair breeds of st. croix and barbados were pasture-mated to dorset rams over a 4-yr period at the dixon springs agricultural center in southern illinois. booroola merino sires were homozygous for the fecb allele for high number of ovulations. the effects of age of ewe, sex of lamb (where appropriate), breed of dam, and breed of ...19957673054
performance of hair breeds and prolific wool breeds of sheep in southern illinois: effect of breed of service sire on lamb production of suffolk and targhee ewes.the effects of year, age of ewe, sex of lamb, breed of ewe, and breed of service ram on fertility, prolificacy, lamb survival, lamb weaning weight, and ewe productivity of suffolk and targhee ewes mated to finnsheep, combo-6, booroola merino, st. croix, and barbados rams were estimated. matings were in four consecutive years using three rams per breed of service ram each year, with a total of 758 ewe-year observations. there was a significant effect of year on fertility, prolificacy, and ewe pro ...19938440650
performance of hair breeds and prolific wool breeds of sheep in southern illinois: wool production and fleece quality.the objective of this study was to compare weight and quality of fleeces of different f1 ewe types produced from breeds with a broad range of fleece types. weights of 629 fleeces produced during 1988 through 1991 from f1 ewes that were daughters of suffolk and targhee dams and finnsheep, combo-6, booroola merino, st. croix, and barbados sires were recorded. staple length was measured on the mid-side of each ewe present in 1991. fleeces shorn in 1991 were sent to a wool marketing organization, an ...19968778106

application of phylogeny reconstruction and character-evolution analysis to inferring patterns of directional microbial transmission.i used phylogenetic analyses to reconstruct patterns of directional interspecific transmission during a pseudorabies virus outbreak in illinois, usa, in 1989. isolates were recovered from five species: cattle, sheep, goats, pigs, and raccoons (procyon lotor). i generated dna sequences for 16 isolates of pseudorabies virus at the glycoprotein c gene, from which i constructed phylogenetic trees. i then used these trees, in combination with parsimony-based analyses of character evolution, to infer ...200314516717
orf virus infection in humans--new york, illinois, california, and tennessee, 2004-2005.orf virus is a zoonotic parapoxvirus endemic to most countries in the world and is principally associated with small ruminants (e.g., sheep and goats). human orf infections appear as ulcerative skin lesions after contact with an infected animal or contaminated fomite. this report summarizes the epidemiologic and laboratory investigations of four sporadic cases of human orf infection, emphasizing the temporal association between human lesions and skin trauma or recent flock vaccination with live ...200616437055
cryptosporidiosis outbreaks associated with recreational water use--five states, 2006.cryptosporidiosis is a gastrointestinal illness caused by parasitic protozoa of the genus cryptosporidium and can produce watery diarrhea lasting 1-3 weeks; one or two cases per 100,000 population are reported annually in the united states. fecal-oral transmission of cryptosporidium oocysts occurs through ingestion of contaminated drinking or recreational water, consumption of contaminated food, and contact with infected persons or animals (e.g., cattle or sheep). unlike bacterial pathogens, cry ...200717657205

accidental ammonia exposure to county fair show livestock due to contaminated drinking water.nitrogen based fertilizers represent an important element in the farm economy, but their storage and use are associated with major risks to livestock and humans. an accidental ammonia exposure occurred at a midwest county fair in illinois. six deaths occurred in show livestock; a holstein cow, 3 holstein heifers, a goat, and a lamb. mortality was associated with consumption of water inadvertently contaminated with a liquid fertilizer containing ammonium nitrate and urea commonly used for irrigat ...200212361112
comparative utility of restriction fragment length polymorphism analysis and gene sequencing to the molecular epidemiological investigation of a viral outbreak.restriction fragment length polymorphism (rflp) analysis and partial-genome dna sequencing are commonly used to infer genetic relationships among pathogens. this study compares the application of both techniques to the analysis of 16 pseudorabies virus isolates collected during a 1989 outbreak. genetic distances derived from rflp and dna sequence data were not significantly correlated with geographic distances between farms from which isolates were collected. rflp-based genetic distance was, how ...200111467798
performance of hair breeds and prolific wool breeds of sheep in southern illinois: lamb production of f1 ewe lambs.the effects of year, sex of lamb, breed of dam, and breed of sire were estimated for age at puberty, breeding to lambing interval, breeding weight, ovulation rate, and ewe productivity (weight of lamb weaned per ewe exposed) and its component traits in f1 ewe lambs produced from suffolk and targhee ewes mated to rams of three wool breeds (finnsheep, combo-6, and booroole merino) and two hair breeds (st. croix and barbados). ewe lambs were pasture-mated to dorset rams when they were 8 to 10 mo of ...19938376223
