There is a need for collaboration by entomologists and engineers on R and D to develop cost effective rearing systems. An idea under consideration is a modular facility capable of simultaneously rearing more than one pest species. This could initially be used for SBF eradication, then for the ...
Sheep rearing in India is an inseparable component of mixed farming system in view of the prevailing socio-economic conditions in the country where per capita land holdings is hardly 0.2 hectares. Sheep in India are predominantly maintained on natural vegetation on common growing lands, waste lands...
OPA has been recorded in the major sheep-rearing areas except Australia and New Zealand. The disease has also been described, although more rarely, in goats and moufflons. The etiological agent of OPA is jaagsiekte sheep retrovirus (JSRV) (Palmarini et al.,1999), which is a retrovirus and...
cuprina4. However, due to problems in mass-rearing the strain (breakdown of Y:autosome translocations, semi-sterility, fungal infection) and declining wool price, the trial was never extended to mainland Australia. More recently, Mahon has suggested that SIT be reconsidered for control of L. ...
Australia’s mutton glut has sent prices tumbling, and some farmers are compelled to give their sheep away to save costs instead of rearing them on-farm. 澳大利亚的羊肉供过于求导致价格暴跌,一些农民被迫将羊送人以节省成本,而不是在农场养羊。
Breeding work with sheep includes selection, culling, and crossbreeding and is directed toward obtaining and rearing animals with desirable qualities. The principal feeds are grasses from natural and cultivated pastures, hay (mainly small-stalked), spring straw, silage, and concentrates. Sheep are pas...
health monitoring, vaccination, biosecurity, and preventative medicine programs; production standards and management practices consistent with the industry; vermin and insect control measures (especially flies and other flying insects); rearing programs and condition of young stock; and animal housing facilit...
In 3 winters the effect of housing in wooden shelters open to the south or in closed sheds of brick was studied in 3 groups of 20 Merino ewes lambing in December and 4 groups of 13 and 4 groups of 15 yearling lambs. Sheep were housed from November to April; straw bedding was ...
Half of the lambs were bottle fed in isolation by one shepherd during the first 3 weeks while the other half was fed alternately by three shepherds. The lambs were then tested at 3, 6 and 14 weeks of age to find out the effect of rearing conditions on the response to isolation and to...
"By rearing the original Nimmitabel larvae on homogenized liver containing the susceptible discriminating concentration of cyromazine, a pure-breeding strain comprising only the 4% resistant individuals from the original population was created in the laboratory." "The original cyromazine-resistant 'Nimmi...
