Native Pasture

Age-balanced breeding flocks of 40 ewes of the super-fine Merino (M) and Border Leicester (BL) breeds were set-stocked together on semi-improved native pasture for three years. The M ewes grew more wool and weaned more lambs of a lighter weight, while the BL ewes were heavier than the M ewes at all weighings. During the last year the BL ewes experienced an overall weight loss not shown by the M ewes, which was reflected in increased mortality. Mortality within the BL breed was high, 70% compared with 17.5% for the M. Pneumonia was the primary cause of death.

Tussock Grasses

The diet of the eastern grey kangaroo and wallaroo was compared at 2 sites, Lana and Newsholme, in the New England tablelands of New South Wales. At Lana, the pastures had been fertilized for 20 yr and were dominated by low-fibre grasses such as Bothriochloa, Eragrostis, Sporobolus, Microlaena, Danthonia and Vulpia; some paddocks had been sown with introduced grasses, Phalaris, Festuca and lucerne. Coarse tussock grasses such as Poa spp., Stipa and Danthonia pallida predominated at Newsholme. The major difference in the diet of the 2 spp. was in winter when individuals on the unimproved area at Newsholme ate a higher proportion of tussock grasses and less low-fibre grass. Both spp. consistently selected for low-fibre grass leaf; they did not differ in their use of plant parts. The diets contained many plant spp. in common, although there were major differences in the use of several spp. The plant spp. favoured only by the wallaroo were of a higher quality than those favoured only by the grew kangaroo.

The diets and growth rates of rainbow trout in the Wollomombi and Guy Fawkes Rivers in northern New South Wales were examined. The growth rate of trout in the Wollomombi River was much higher than that of fish in the Guy Fawkes River. Spearman rank correlation coefficients indicated that stream type was more important than fish size in determining the composition of the diet of the trout. Benthic invertebrates formed the largest component of the diet in both streams: 66.0 and 63.0% of ash-free dry weight (AFDW) in the Wollomombi River and the Guy Fawkes River, respectively. Trout in the Wollomombi River consumed more nektonic prey (33.3% of AFDW) than fish in the Guy Fawkes River (3.7% of AFDW). In contrast, surface food (aquatic imagines and terrestrial insects) made up a much higher proportion of the diet of trout in the Guy Fawkes River (33.9% of AFDW) than in the Wollomombi River (0.6% of AFDW). Crayfish were a major component of the diet (in terms of AFDW) in both streams, their proportions increasing with fish size. The significance of crayfish in relation to fish growth is discussed.

A range of temperate annual and perennial legumes, naturalized or commonly sown in the area, was examined at three field sites in low fertility soils derived from granite on the south western slopes of the New England Region, New South Wales. They were compared over a four year period in terms of their persistence, dry matter and nitrogen production and their compatibility with associated temperate perennial grasses, The response of sown grass to nitrogen fertilizer application was also examined in the absence of legume. Ten legumes were examined at one site and six of these at the other two sites. In general, nitrogen yields were ranked similarly to total dry matter yields of all treatments, including grasses in the absence of legume. However, the legumes were ranked differently in terms of productivity of the legume component and productivity of associated grass. At all sites lucerne gave the highest yields of total dry matter and of legume and the lowest yield and persistence of associated grass-comparable to grass growing in the absence of legume or applied nitrogen. Subterranean clover was ranked second or third in total dry matter yield, depending on site, but provided the highest yield of associated grasscomparable to grass receiving high levels of applied nitrogen. Under this legume soil nitrogen levels tended to be highest. Rose clover, sown at one site only, yielded more legume dry matter than subterranean clover but grass yield was comparable to that with lucerne. The results suggest that subterranean clover is the superior legume for successful mixed sowings although inclusion of white clover could be justified. Lucerne appears to be best sown as a pure sward.
