ABSTRACT Understanding the ecological roles of apex predators remains an important field of study. The influence of apex predators on ecosystems can be either profound or negligible in different situations, and uncertainty still exists about the ecological roles of most top-predators, including Australian dingoes. This uncertainly is maintained by a dearth of experimental evidence investigating their roles. Such evidence is indispensable if dingo management is to be evidence-based. In this report, we discuss a recent experiment where dingoes were released on to an island as vertebrate biocontrol tools intended to eradicate feral goats and restore native vegetation being threatened by the goats. The experiment was successful, and the dingoes reduced the goat population to one or perhaps two male goats within ~2 years. This predator introduction experiment elucidated dingo’s effects on small livestock, their per capita predation rates, and their invasiveness or their ability to adapt and change their environment. The experiment confirmed that dingoes have the capacity to decimate populations of small livestock species and trigger a trophic cascade by reducing herbivory on vegetation. We encourage further manipulative experiments to explore the ubiquity of these results in different contexts.

An aerial survey of 966,000 km2 of the arid/semi-arid rangelands of Queensland and New South Wales in the winter of 1992 indicated a minimum feral goat population of almost 1 million animals (density 0.97�0.12/km2). Observed density (f standard error) was higher in New South Wales (1.51�0.23/km2) than in Queensland (0.47�0.09/km2).

Goat Population

In recent years, goat breeds with a dairy-meat-wool or combined productivity type, represented by local breeds that are bred mainly in the foothills and mountainous regions of the North Caucasus, Altai, Tyva and Khakassia, have become increasingly widespread in Russia. The Karachay goat population is the most interesting for research, since in their breeding was aimed at obtaining animals with a number of unique productive characteristics and capable of producing the required outputs under the harsh conditions of the mountain and foothill zones of the Caucasus. In view of the limited research on these animals, in particular their reproductive functions, the aim of this study was to investigate the natural implementation of the reproductive function of the Karachay goats in different geographical areas of breeding. There are slight differences in some parameters of Karachay goat reproduction in high mountain zone (from 2000 m a.s.l.) and middle mountain zone (1000–1500 m a.s.l.). An important conclusion is that the recognized low fertility of the Karachay goats is not genetically determined. Analyzing the number of ovulations and fresh yellow bodies in the ovaries by laparoscopy using Karl Storz (Germany) endoscopic equipment, the authors found a potential fecundity of 3.1 (2.8 to 3.4).

Foot And Mouth

Background: Foot-and-Mouth Disease (FMD) remains a serious threat to the Indian livestock sector due to significant economic loss associated with it. Systematic vaccination of large ruminants over the years has lead to a gradual reduction in the number of disease outbreaks in India. However exposure to FMDV infection in small ruminants has been recorded during the past few years (Rout et al. 2013). Sheep and goat population have not been vaccinated so far against FMD under the FMD-Control program (FMD-CP). The present study highlighted the outbreak of FMD in small ruminants in Karnataka, India.Methods: During the period 2018-19, seven suspected FMD outbreaks among sheep population in Bellary and Tumakuru districts of Karnataka state were investigated. Tongue epithelium (oral swabs) and foot lesions (n=23) from clinically affected sheep and tissues such as heart, lung, liver, spleen, lymph nodes and kidneys from lambs during post mortem (n=67) were collected. All the samples were processed in the laboratory for the detection of FMD virus antigen by employing Serotype differentiating antigen detection ELISA and by multiplex PCR. Heart tissue samples were also collected in buffered formalin for histopathology study and processed by routine paraffin embedding technique and stained with Hematoxylin and Eosin (H and E). Serum samples from the recovered animals were collected and screened by NSP-ELISA and LPB-ELISA to check the antibody status in the affected herd. Result: A total of seven suspected outbreaks of FMD involving 688 small ruminants was investigated. The outbreak of FMD due to FMDV serotype O was confirmed by ELISA and multiplex PCR assays. Clinically, the affected adult sheep showed typical signs of FMD, while mortality in young lambs was observed without apparent signs of disease. Histologically, heart tissues from FMD affected lambs showed myocardial necrosis with marked aggregations of lymphocytes and neutrophils in the myocardium and perivascular spaces. History of FMD outbreaks in cattle and common grazing land for the livestock, as well as sheep within the reach of these villages, may be the major contributing factors for the outbreaks in sheep populations.

To increase goat-meat production, this study has been aimed to evaluate goat-meat production potentiality using different management strategies of goat-population rather than goat-meat productivity management in Bangladesh. Simulation Matrix (SIMM) model was used under three scenarios of goat-population management strategies such as Scenario1(Base rate): 2 kids/year production with 30% kid mortality, Scenario 2: Production of 6 kids/year with 30% kid mortality and Scenario 3: Production of 6 kids/year with 10% kid mortality to analyze their impact on goat-meat production in Bangladesh. Results showed on average only 270.09 thousand ton /year of goat-meat can produce at the existing rate (2 kids Production/year with 30% kid mortality). If it is possible to increase kid production up to 6 then can produce on average 23714.4 thousand ton/year of goat-meat. Further, it is possible to reduce the kid mortality rate up to 10%, goat-meat is the highest 932430.0 thousand ton/year. Result indicated a great positive impact of goat-population management strategies on goat-meat production. Therefore, 10% kid mortality rate with 6 kids/year production of goat-population management could be suitable management or best strategy for higher goat-meat production in Bangladesh.
