Genetics of Resistance to Fleece Rot and Footrot
نویسنده
چکیده
Fleece rot and footrot are two bacterial skin diseases of potential significance in sheep. Both diseases are associated with sheep production in high rainfall-environments. Meece rot is currently the most efficient indicator trait known for genetic improvement in resistance to body strike. Exploitation of genetic variation in resistance to fleece rot is feasible through selection of sheep within flocks, between flocks within strains, and between strains. Identification of resistant genotypes is at present only realistic after expression of the disease, either in the flock, sire evaluation schemes, or suitable flock comparisons. Potential scope for identification of resistant genotypes without the expression of fleece rot, is discussed for both between-flock and withinflock selection.

Ultimate Disease Resistance in Sheep: What Are the Relationships between All Major Diseases?
A study is described which is unique in that resistance to each of the major diseases which affect production in Merino sheep was measured in the same flock under the same environmental conditions. Results indicated that within the one flock, genetic variation exists for resistance to internal parasites, foot-rot, fleece rot and dermatophilosis. Heritability estimates were similar to those publ...
متن کاملA genomics-informed, SNP association study reveals FBLN1 and FABP4 as contributing to resistance to fleece rot in Australian Merino sheep
BACKGROUND Fleece rot (FR) and body-strike of Merino sheep by the sheep blowfly Lucilia cuprina are major problems for the Australian wool industry, causing significant losses as a result of increased management costs coupled with reduced wool productivity and quality. In addition to direct effects on fleece quality, fleece rot is a major predisposing factor to blowfly strike on the body of she...

Fleece rot was induced in 15 young Merino ewes by treatment with repeated application of simulated rain. Forty days after induction, treated and five control ewes were subjected to 50 mm of simulated rain which contained a water soluble dye. Treated ewes absorbed significantly more water than controls (2.3 kg to 1.5 kg). Wool samples were collected at ten cm intervals along the dorsal midline t...
متن کاملReview of Genetic Parameters for Disease Resistance in Sheep in New Zealand and Australia
Genetic factors, mainly heritability estimates, have been reviewed briefly for all major disease traits affecting sheep production in New Zealand and Australia. The traits reported included resistances to nematode parasites, liver fluke, flystrike and fleece-rot, lice, mycotoxic diseases (facial eczema, ryegrass staggers, heat stress caused by ergovaline, and infertility caused by zearalenone),...
متن کاملGenetic of resistance to ear rot causal agent (Fusarium moniliforme) in quality protein maize (QPM) using line×tester analysis
Breeding for QPM ear rot resistant cultivars could offer a reliable environmental and economic control of mycotoxins especially for the resource-poor communities that require inexpensive protein diets. This research aims at evaluating a testcross of QPM inbreds with ear rot resistant cultivars to develop resistant topcrosses with high grain protein quality and yield. Seven QPM inbreds (lines) a...
