Modelling the effect of nematode parasites on the liveweight gain of lambs grazing alternately with cattle
A dynamic model for nematode parasites in lambs which links their adult parasite burden with liveweight gain was extended to investigate alternate grazing with cattle to provide relatively larval-free pasture for finishing lambs. Liveweight performance of weaned lambs was tracked fortnightly under rotational grazing using three cattle:sheep ratios, with three initial parasite burdens and two in...
متن کاملModelling liveweight performance in parasitised lambs under varying grazing rotation lengths
A dynamic model for nematode parasites in lambs which links their adult worm burden with decrease in liveweight gain has recently been developed. This model allows for individual lamb variability in response to parasite infection. We use this model to track the liveweight performance of a mob of weaned lambs under six different grazing rotation length scenarios. In all scenarios, lambs with a l...
متن کاملEffects of supplementary feeding on growth and carcass characteristics of fat-tailed lambs grazing cereal stubble
Despite a shortage of animal feed in Iran, cereal stubble is often underutilized due to agro-economic reasons. On the other hand, lambs fed with a conventional fattening ration deposit a considerable amount of fat; therefore, this experiment was conducted aimed at better utilization of cereal stubble and reducing the fat content of lamb carcasses. Fat-tailed Mehraban and Ghezel ram lambs were p...
متن کاملRumen fermentation and liveweight gain in beef cattle treated with monensin and grazing lush forage.
OBJECTIVE To determine the prevalence of subacute rumen acidosis (SARA) in beef cattle grazing lush pasture and the effect of monensin on reducing SARA and improving animal performance. DESIGN Commercial Angus and Murray Grey steers received a monensin slow-release capsule (n = 19) or remained untreated (n = 19). Cattle grazed an oats crop or tetraploid ryegrass pasture for a total of 91 days...
متن کاملthe role of application of dynamic assessment approach in improvement of iranian efl writing performance at different language proficiency levels
the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...
