Animal Performance

Lamb performance was evaluated for three consecutive summer-early autumn periods on ryegrass (Lolium perenne), white clover (Trifolium repens), chicory (Cichorium intybus), plantain (Plantago lanceolata) or lotus (Lotus corniculatus). Lamb liveweight gains, fasted liveweights at slaughter and hot carcass weights tended to be highest on legumes and chicory and lowest on plantain and ryegrass. Greasy wool weights were significantly higher on lotus and white clover than on chicory, plantain and ryegrass. Greasy wool weight was significantly related to fasted liveweight (R2=0.94-0.99). Protein (%) in herbage accounted for 83-92% of the variability in animal performance; food intake accounted for 57-69% of the variability and was negatively correlated with hemicellulose and cellulose (R2=97.2 and 80.9%, respectively). Thus quality of feed was more important than intake alone in determining animal performance.

Research has shown advantages of including plantain (Plantago lanceolata L.) in grazed perennial ryegrass (Lolium perenne L.)-based dairy pastures. Plantain is typically established in dairy pastures during paddock renovation, and included in a mixture with perennial ryegrass. While perennial ryegrass can persist for years, even decades, plantain plant numbers and productivity decline within a few years of establishment. Maintaining the advantage of plantain requires frequent re-establishment. The current research tested the efficacy of two sowing methods (direct-drilling and broadcasting) and three sowing rates (2.5, 5.0, and 7.5 kg of seed/ha) for establishing plantain in existing irrigated perennial ryegrass pastures. Research was conducted on five dairy farms in northern Tasmania, Australia. Sowing occurred in mid-spring 2017, immediately after paddocks were grazed. Plantain establishment was monitored until early autumn 2018. Paddocks were managed as per normal farm practice, resulting in plantain being first grazed ~4 weeks post-sowing, before plants had developed to the recommended minimum six-leaf stage. Dry weather, timing of first grazing after sowing and insect burden challenged plantain establishment. However, both direct drilling and broadcasting were shown to successfully establish plantain into existing perennial ryegrass pastures.
