Feral Pigs

Eight feral pigs (two boars, four sows and two piglets) were caught in traps using oestrous sows as lures during a control program on a remnant pig population in part of Namadgi National Park during spring, 1990. The program was mostly based on aerial baiting with warfarin. No pigs were caught in traps containing anoestrous sows or in traps containing bait only. Seven unmarked pigs (caught seven days after the cessation of baiting) did not appear to have eaten any warfarin bait. In an earlier pilot trial, two boars were caught at a trap containing an oestrous sow, one of these again in a trap baited only with fermented grain, but no pigs were caught at a trap containing an anoestrous sow. Although not cost-effective as a general technique, this method could be useful in specific circumstances, such as eradication campaigns on islands, if the last few pigs are, or have become bait shy, or are impossible to cull by other methods.

Initial Control

A warfarin poisoning programme to control feral pigs was evaluated on agricultural land in eastern Australia between July and September, 1987. The estimated total population before the poisoning programme was 189 pigs within the 94.4 km2 study area. Poisoned and free-fed bait was offered initially at 69 sites and over a period of 57 days. Only two pregnant sows were believed to have survived the programme which was equivalent to a 98.9% reduction. As a result of breeding and re-invasion a further 38 pigs were removed in the 12 months after the control programme. Cost of initial control was $A39 per pig while cost of maintenance control was $A47 per pig.

Radio Transmitters

The aim of this study was to develop better techniques for controlling feral pigs, Sus scrofa, in the event of an outbreak of an exotic disease than the use of 1080. Trail-baiting with warfarin-treated wheat killed 30 of 32 feral pigs carrying radio transmitters in Namadgi National Park, A.C.T., in May 1986. The casualties took 9.7 � 0.4 (mean � s.e.) days to die (range 6-14) and all died within 2.06 km of the bait trail. The two survivors (both males) were radio-located within 339 m of the poison trails several times, but then moved 5.1 and 1.5 km, respectively, out of the trial area. Home ranges averaged 4.7 � 0.6 km2 (range 0.7-22.6) and the population density was approximately 2 km-2. The pigs' mobility did not alter as death approached. They moved equal distances during the day and the night. Differences in mobility between the sexes were generally minor.

Minimal Evidence

The consumption of five non-toxic, grain-based baits, and the effectiveness of the preferred baits when treated with 1080 in reducing pig numbers, were determined for feral pigs (Sus scrofa) in several areas in the Mediterranean agricultural region of Western Australia. Fermented wheat with added blood and bone proved an effective attractant for feral pigs, and for determining areas of pig activity. Wheat and malted barley were the preferred baits, there was a variable response to lupins, and commercial pig pellets were consumed least. Malted barley, barley, and wheat treated with 1080 gave good reductions in pig numbers at the localised scale. Where pigs would eat lupins, 1080-treated lupins were usually effective in reducing pig abundance. In some instances, further evidence of feral pig activity was not seen on several sites for several months after poison-baiting occurred. The addition of a small amount of unpoisoned grain to mask the presence of 1080 did not increase the take of treated bait (P < 0.05). Although finding poisoned pigs was difficult owing to the terrain and the presence of bush remnants, the poisoned pigs found (n = 90) were often within 200 m of active bait stations. 1080-poisoned pigs included both adult (≥25 kg) and non-adult pigs of both sexes. Body mass of these pigs ranged from 4 to 90 kg. In all, 42% of poisoned adults found (n = 50) were 50 kg or more. There was minimal evidence of bait take by non-target species, and, where this occurred, it generally involved the consumption of the fermented wheat attractant by kangaroos (Macropus spp.) and foxes (Vulpes vulpes). Six foxes were known to have been poisoned with 1080-treated grain (4 with malted barley, 2 with wheat). Excluding foxes, no other non-target animals, including native species, were found dead during the intensive searches for poisoned pigs.

Test Conditions

The toxicity of sodium monofluoroacetate (1080) to captive feral pigs, Sus scrofa, was assessed over a range of doses (1.50-21.3 mg 1080 kg-1 bodyweight) administered orally in wheat bait to 80 animals. Calculated LD*50 was 4.11 mg 1080 kg-1 (95% fiducial limits: 3.02-5.34 mg kg-1) and LD*9O was 11.25 mg kg-1 (8.05-21.69 mg kg-1). The incidence (98%) and frequency (mean � SD = l3.6 � 6.7 overall) of vomiting were high. Frequency of vomiting was unrelated to log*10 dose (r= -0.015; N= 80; NS), although time until vomiting began (r= -0.558; N=77; P<O.05) and time until death (r= -0.391; N=47; P<0.05) had a significant negative association with log*10 dose. Median latency was 49 min (range 10-350 min; N=77) and median time until death was 244 min (range 131-7200 min; N=47). Sex and bodyweight had no effect on frequency of vomiting, time until death or prognosis. Feral pigs yere much less sensitive to 1080 under these test conditions than those in earlier studies. Because the present experiment seems likely to resemble field situations, these results warrant careful examination of field intake and mortality of feral pigs during 1080 poisoning.
