SUMMARYOn a coastal farm in New South Wales where beef and dairy cattle production was carried on side-by-side, separate pasture plots were contaminated with eggs of Ostertagia ostertagi by calves from each production system in autumn, winter or spring. Successive groups of parasite-free tracer calves grazed on the plots for 14 days at 4-week intervals and were then killed for worm counts 14 days after removal from pasture. On all plots, the proportion of inhibited early 4th-stage larvae in tracer calves reached a maximum in spring, and was consistently and very significantly higher in calves which grazed plots contaminated with O. ostertagi of beef cattle origin. Factors which may be responsible for this difference between beef and dairy cattle populations of O. ostertagi are discussed.

The effect of phosphorus supplementation on liveweight and digestibility of dietary components was studied in two experiments with beef steers at Grafton, New South Wales. In one experiment, three groups of 15 steers grazed a pasture that was deficient in phosphorus and nitrogen throughout the year and received a supplement of 0, 35, or 70 g phosphorus each week for twelve months. The phosphorus supplements had no effect on liveweight. In a second experiment, five pairs of steers were individually fed a phosphorus deficient diet to which urea, molasses, and minerals were added. The steers received a daily supplement of either 0, 2, 4, G, or 8 g phosphorus. The supplements had no effect on liveweight or apparent digestibility of dry matter, energy, or nitrogen. The apparent digestibility of phosphorus increased with supplementation up to 4 g a day (P<0.001) but there was no further increase at the higher rates. The apparent retention of phosphorus increased with each increment of phosphorus (P<0.01). It is concluded that supplements of phosphorus will not improve liveweight performance when beef cattle graze natural pasture of such low quality as that frequently found in north-eastern New South Wales.

Gross Margins

The ‘Regional Combinations’ project and its biophysical outcomes have been described in several other papers in this special edition. The information provided in these papers allows an evaluation of the most profitable beef cattle production systems across different environments in southern Australia. In this paper, the focus is on the New South Wales experimental site where the trial animals were finished in a feedlot. The data identified liveweight gain as the biggest driver of profitability of production. Between growth treatments, there was a large difference in the gross margins before feedlot entry between the ‘fast’ and ‘slow’ treatments favouring the fast-grown animals, even after accounting for the higher cost of producing pasture capable of sustaining faster growth. However, the slow growth treatments consistently outperformed the fast growth treatments in the feedlot. In terms of breeds, the European breed types consistently outperformed the Wagyu breeds. There were no time-of-calving experiments in New South Wales.

The Mean

The effects of anthelmintic treatments on the growth of young beef cattle on the Tablelands and North Coast regions of New South Wales were assessed by comparing the liveweight gains of treated and untreated cattle grazing the same pasture. Anthelmintic treatments were given every 4 weeks to suppress gastrointestinal nematode infections and at strategic times. These times were at weaning (in autumn), during winter and in the late summer of the following year, and were chosen to coincide mainly with increasing worm burdens. After weaning, the mean cumulative liveweight responses of suppressively treated groups were often significantly greater during winter and early spring. Strategic treatments in winter but not in autumn also gave a significant liveweight response in some trials. Suppressively treated groups showed considerable variation in their growth rates during spring. This most likely reflected year-to-year variations in pasture growth, but the mean cumulative liveweight responses of several treated groups were significantly greater than those of untreated groups. These results suggest that helminth infections affected the growth of young beef cattle in both winter and spring. There was little liveweight response to suppressive treatments in the late summer and autumn of the second year, when the cattle were 16-20 months old. At the end of autumn, these cattle were usually 20-30 kg per head heavier than untreated cattle. Strategic treatments given in late summer to cattle grazing with untreated cattle did not produce any substantial liveweight response.
