As part of a research programme designed to identify biological agents for the control of sheep scab, the pathogenicity of the fungus Metarhizium anisopliae to Psoroptes mites in the presence of sheepskin and wool was examined in the laboratory. No inhibitory effects of skin and wool were observed and high levels of infection were recorded. Subsequently the pathogenicity of formulations of both...

The increasing availability of crude glycerin from the biodiesel industry has led to an interest in its use as an energy source in ruminant diets. However, its effects on ruminal fermentation patterns and methane (CH4) production are unclear, and there are no reports on the effect of its inclusion in the diet on wool production or growth of Merino sheep. Thus, the objectives of this study were ...

The aims of this study were to estimate the on-fam economic cost of ovine Johne's disease (OJD) based on collected incidence and mortality data, and the benefit-cost of OJD vaccination in typical OJD affected flocks in New Zealand after having vaccinated for a number of years. Owners of 20 sheep breeding and finishing farms known to be clinically affected by ovine Johne's disease in New Zealand...

The article presents the dynamics of changes in live weight for a year, measurements, body build indices and productivity one-year-old pure-bred Kazakh fine-wool female lambs crossbreeds different bloods with German meat merino, when creating sheep breed south-east Kazakhstan - “Etti merino”. resulting crossbred offspring are characterized as large animals, high good forms.

One hundred years ago, there were more than 48 million sheep in the United States. In 1910, they were valued at $4/head, with 43% of income coming from the sale of sheep, lambs, and meat and 57% coming from wool. Over the years, fluctuations in this ratio have challenged the breeder and researcher alike. By 2007, sheep numbers had declined to 6.2 million, with the average sheep shearing 3.4 kg ...

Field studies were conducted in Australia to determine the efficacy of CLiK® Spray-On (50 g/L dicyclanil) in protecting unmulesed sheep from naturally occurring blowfly strike. Unmulesed sheep were treated on day 0 and inspected for flystrike at defined intervals thereafter. Any strikes detected were documented and resolved with a flystrike dressing. In the interest of animal welfare, untreated...

In Southern Patagonia, grasslands are the principal food resource for sheep reared meat and wool as main provisioning ecosystem services (ES). The objective of this study was to model lamb production ES at a regional scale using climatic, topographic, vegetation variables from farms across Santa Cruz province. At level, animal yield ranged 0.25 0.69 g lamb/m2/yr 0.10 0.19 greasy wool/m2/yr. We ...
