Serradella line evaluation - stage 3.

Trial 85AL86 Location: South Stirlings. To evaluate five promising lines selected from variety trials, in terms of herbage production and long term persistence

The effect of nitrogen on pastures and subsequent sheep production.

Trial 89MT1 Location: Mt Barker Research Station To measure the effect of autumn/winter application on: 1. Pasture growth rates and composition 2. Sheep production using pregnant/lacting ewes. Trial 89KA6 Management systems for sheep. Location: Kojonup To measure the effects of set stocking and strip (rotation) grazing on: 1. Pasture production, composition and quality. 2. Sheep production (liveweight, condition score, wool growth rate, fibre diameter strength and vegetable matter contamination)

Polymorphisms Detected in the Tyrosinase and MATP (SLC45A2) Genes Did Not Explain Coat Colour Dilution in a Sample of Alpaca (Vicugna pacos)

The molecular basis of inheritance of alpaca fibre colour is poorly understood. However, colour dilution genes are anticipated to be causing a major effect on alpaca fibre colour. Candidate genes for dilutions included tyrosinase (tyr) and membrane associated transport protein (matp), both of which have been associated with coat colour dilution in other species. The coding regions of the tyr and matp genes were sequenced in 24 animals with various colour phenotypes. No polymorphism found in the coding region of tyr and matp exons 1, 3, 4, 5 and 7 could account for the dilutions in fibre colour observed

Management systems for sheep.

Trial 89KA6 Location: Kojonup To measure the effects of set stocking and strip (ration) grazing on: i) Pasture production, composition and quantity ii) Sheep production (liveweight, condition score, wool growth rate, fibre diameter, strength and vegetable matter contamination)
