Can a return to small ruminants increase profitability and drought resilience in the semiarid rangelands of northern Australia?

The anthelmintic resistance has limited the control of gastrointestinal nematodes of small ruminants and thus has awakened interest in the study of plants extract as a source of anthelmintics. These experiments were carried out to evaluate the in vitro efficacy of Jatrophacurcas latex extract against Haemonchuscontortus larval motility. To evaluate the larvicidal activity, H.contortus L3 were incubated with the extracts with varying concentration of 5 mg/mL, 10 mg/mL, 15 mg/mL and 20 mg/mL at 27°C for 48, 72 and 96 hrs. The results were subjected to the Kruskal-Wallis test (P less than 0.05). The extracts showed dose-dependent larvicidal effects. These results suggest that J.curcas can be used to control gastrointestinal nematodes of small ruminants.

: Brucellosis caused by bacteria of the genus of Brucella remains a major zoonosis in the widely world, which is an infectious disease with a severe economic impact on animal husbandry and public health. The genus of Brucella includes ten species and the most prevalent is Brucella melitensis. The diagnosis of Brucella melitensis ruminant brucellosis is based on bacteriological and immunological tests. The use of vaccines and the false-positive serological reactions (FPSR) caused by other cross-reacting bacteria represent the immunological contexts. This complex context results in the development of the large number of diagnosis of Brucella melitensis brucellosis. The aim of this article is to briefly review the detection methods and compare the superiorities of different tests.

The Mean

Ruminal acidosis is an important clinical emergency in small ruminants. In this study, eight healthy farm goats and 24 goats presented at TVCC of the college of Veterinary Sciences and A.H., Anand with clinical signs of ruminal acidosis and having rumen liquor pH below 6 were examined for alterations in the ruminal fluid and serum biochemical parameters. Among various rumen fluid parameters evaluated, the mean values of rumen fluid pH decreased significantly (4.71±0.11 vs. 6.90±0.10), while sediment activity time (46.67±1.20 vs. 24.50±0.78 min) and methylene blue reduction time (29.50±0.73 vs. 10.03±0.27 min) increased significantly in acidotic goats. The normal greenish, aromatic viscous color, odour and consistency of rumen fluid of healthy goats also changed to milky grey/creamy, sour/pungent watery in acidotic goats. The rumen protozoal activity decreased to nil in acidotic goats as compared to the healthy goats. Among various serum biochemical constituents, the mean values of glucose (92.43±1.37 vs. 74.13±1.83 mg/dl), BUN (26.49±0.47 vs. 22.63±1.19 mg/dl), serum creatinine (01.01±0.02 vs. 00.83±0.02 mg/dl) and albumin (03.22±0.03 vs. 03.05±0.05 g/dl), ALT (56.75±1.55 vs. 27.88±1.14 IU/L) and AST (93.25±1.82 vs. 54.00±1.75 IU/L), increased significantly, while there was significant decrease in serum calcium (09.09±0.14 vs. 10.29±0.08 mg/dl) in acidotic goats. The mean values of alkaline phosphatase (IU/L) in acidotic goats increased non-significantly from the base values of healthy goats.

Taxation System

In the recent Fortescue decision, the High Court made some interesting observations regarding interpretation of the word ‘discrimination’ in the context of the Federal Government's power with respect to taxation in s 51(2) of the Australian Constitution. Coincidentally, the Federal Government has commenced consideration of options for the development of northern regions of Australia. Of course, one option would be to introduce a variable taxation system to encourage businesses and individuals to be based, and/or invest, in northern Australia. This article considers possible constitutional issues associated with variable taxation schemes overtly favouring businesses and individuals based in the ‘north’, given the recent High Court decision.
