Resumen

In the conditions of the hot climate of the South of Russia, purebred Texel sheep of Australian breeding by the beginning of the main breeding season in sheep breeding in the North Caucasus zone (end of August, fi rst decade of September) have reduced sexual activity, ejaculate volume and unsatisfactory seed quality, compared with Texel sheep of Finnish breeding and Kuban Lincolns. The reproductive ability of texel sheep of Australian breeding is restored at a later date.

Resumen

Summary. White clover was introduced to Australia with the early European settlers in the late 18th century and is now the most valuable pasture legume in high rainfall temperate regions of Australia. Through a process of ingress and naturalising in conjunction with pastoral expansion during the 19th century and widespread pasture improvement in the 20th century, white clover now occupies 6 million hectares in Australia and is of major significance for the sheep, beef cattle and dairy industries. This paper describes these historical influences on formation of the white clover zone in Australi

Resumen

Sheep worm infections increasingly threaten the profitability of the Australian sheep industry as the prevalence and severity of anthelmintic resistance continues to rise. Field experiments have demonstrated that the use of drenches that are of reduced efficacy due to resistance can reduce wool production by 10% and significantly reduce sheep sale value. The major factor in benzimidazole (BZ) and levamisole (LV) resistance, and in part macrocyclic lactone (ML) resistance in Haemonchus contortus, is considered to be the excessive frequency of treatment. In Ostertagia circumcincta, ML resistance

The sheep grazing tolerance of a diverse range of lucerne germplasm (Medicago sativa subspp. sativa, falcata and caerulea) was investigated at Roseworthy in South Australia. Lucerne entries were established on a sandy loam soil in 1998 and managed with rotational grazing management for the first 12 months. Continuous grazing by sheep in the following year reduced the plant density of each entry as measured by plant frequency estimates by 2–98%. Lucerne was allowed to recover, then grazed continuously for another 12 months. There was great diversity in tolerance to sheep grazing among the entri

Resumen

South Australian Merino sheep were selected on the basis of high or low estimated breeding values (EBV) for wool growth rate (W), but with similar bodyweight, follicle density, and mean fibre diameter. Differences in the level of expression of keratin genes were examined in the skin of these sheep to test the hypothesis that divergence in EBV for wool growth is related to the production of wool proteins differing in sulfur (S) content. Further, it was proposed that this differential gene expression would be most pronounced when the supply of S amino acids to the animal was increased. Sheep sel

Resumen

Phalaris (Phalaris aquatica L.) is a valuable perennial grass for grazing and land-care purposes in south-eastern Australia. Population survival is predominantly by clonal spread, whereas seedling recruitment is limited by low longevity in the seedbank, ant seed harvesting, and competition from other species. We examined the possibility that breeding and selection could alter the seed dispersal pattern of phalaris, and that this change would result in an increase in seedling recruitment under reduced competition created by grazing.

A survey to determine the distribution and abundance of New Zealand fur seals, Arctocephalus forsteri, in South Australia and Western Australia was conducted in January-March 1990. Minor surveys were conducted in the summers of 1987-88, 1988-89 and 1990-91. Although the surveys were primarily of black pups in breeding colonies, opportunity was taken to count fur seals of all age-classes, including those in non-breeding colonies. Pups were counted and, in more accessible and larger colonies, numbers of pups were estimated by a mark-recapture technique. The latter technique gave higher estimates

The aim of this study was to analyze tendencies in the population of Patch Faced Maritza sheep breed and estimation of sustainability of the breeding program for this breed by analyzing continuity of farmer`s breeding activity. Patch Faced Maritza sheep breed is a local Bulgarian sheep breed typical for lowland regions of South Bulgaria and could be successfully used as local genetic resource in productive strategies for milk and meat production. Data about breeders and population structure of the breed during 27 years (1991-2017) were provided by the breeding association of Maritza

Resumen

Trichostrongyloid nematode infections of weaner sheep were investigated at the Turretfield and Minnipa Research Centres in the cereal zone of South Australia over a three-year period (1982-1985). Acquisition of nematode larvae from pasture occurred over a limited period each year, principally during the winter months, and coincided with the elimination of, or a reduction in the numbers of adult nematodes; sheep subsequently resisted challenge by infective larvae. Faecal egg counts were elevated during the summer, but declined to negligible levels during the winter months when larval challenge

Resumen

The migration routes of wide-ranging species can be difficult to study, particularly at sea. In the western South Pacific, migratory routes of humpback whales between breeding and feeding areas are unclear. Male humpback whales sing a population-specific song, which can be used to match singers on migration to a breeding population. To investigate migratory routes and breeding area connections, passive acoustic recorders were deployed in the central New Zealand migratory corridor (2016); recorded humpback whale song was compared to song from the closest breeding populations of East Australia a

Resumen

Crested terns breeding in the Fremantle area of south-western Australia nest over an 8-month period, from early April to early November. However, laying is markedly bimodal, with subseasons in autumn and spring. Observations of individually marked breeding crested terns indicated a sedentary population utilizing a number of alternative, traditional colony sites all of which were within the study area. Individual crested terns tended to lay in the same part of the season as in the previous year. Colonies made up of terns with similarly phased reproductive cycles formed at different times within

Conventional production methods are widely used in agricultural production in order to provide healthy and balanced nutrition to the growing population in the world. However, the chemical substances used to increase the efficiency and combat against diseases in plant and animal production affects human and animal health by passing to water and soil. Today, consumers around the world, especially in developed countries such as the European Union (EU) countries, the United States (USA), Japan, Canada and Australia are need of consumption of agricultural products that do not harm the environment a

Our research aimed to analyse the current state of the sheep industry in Ukraine, to highlight the geographical location of genetic resources, to describe the state of the breeding work, and to form the proposals for the development of this branch in the future. The date from the State register of breeding farms for 2005-2019 and statistical reporting were used for analysis. It is shown that Ukraine has good natural and climatic preconditions, as well as customer demands for the development of the sheep industry. In addition to the domestic market, it is necessary to look for opportunities to

Resumen

The white-breasted robin, Eopsaltria georgiana, is endemic to south-western Australia. We studied breeding, dispersal and survival in known groups from 1978 until 1987, with some groups followed until 1992, in Eucalyptus diversicolor (karri) forest near Manjimup, Western Australia. E. georgiana bred cooperatively, with 66% of groups including one or more birds in addition to the breeding pair (mean group size 3.1); these helpers were predominantly males and assisted the senior male in feeding the female on the nest and the young and defending the territory. The survival of adults was high (mal

Texto completo

Resumen

Causes of mortality in weaner sheep subjected to differing regimes of anthelmintic treatment were investigated at Kybybolite, S.A., between 1976 and 1981. The greatest mortality occurred in untreated sheep during the winter months, and was directly attributable to nematode infections, principally Trichostrongylus vitrinus. Deaths occurred during the summer months of the later years of the experiment. Nematode infections were considered to be a predisposing cause, with anaemia possibly due to infection with Eperythrozoon ovis as the precipitating factor in mortalities.

The reproductive seasonality of the bush rat (Rattus fuscipes greyi) was investigated in Scott Creek Conservation Park near Adelaide, South Australia, by catch and release trapping conducted at irregular intervals over a 4-year period in a population of higher density than previously reported for this species. A seasonal pattern in breeding activity was observed with the production of young in spring and summer (October-February) with a peak in December. There was seasonal variation in the testicular index of males with minimal values from April to June. Some animals may have retained the abil

Five species of phocid seal of the Southern Ocean and Antarctica come ashore occasionally on the southern Australian coast but do not breed there. We document records (specimens and sightings) of visits to South Australia (SA) by southern phocids from 1883 until August 2011. We used records from the SA Museum, reports from coastal officers of SA Department of Environment and Natural Resources (DENR), the DENR fauna database, information from the public, the literature and newspapers. Thirty-six southern elephant seal records included two births, in November 1932 and October 1986. The latter pu

Resumen

The current knowledge of the nature and distribution of sodic soils in South Australia is reviewed. The agriculturally developed area of South Australia lies south of latitude 32-degrees-S. and is mainly used for low intensity grazing and dry land cereal/sheep production. A high proportion of the State, including much of the high rainfall area, has soils which are sodic (>6% ESP) through a significant proportion of the profile but information on the precise nature of sodicity in these soils is limited. Where exchangeable cation data axe available, the analytical techniques used often did no

Resumen

Descriptions are given of 2 study sites in the south-west of Western Australia, on which rabbit numbers were monitored. Breeding seasons began in March or April, with the onset of winter rain, and rabbit numbers peaked in October-December, followed by a fall over the non-breeding period in summer. Winter epizootics of myxomatosis, which were spread by Spilopsyllus cuniculi, caused severe declines in rabbit numbers at both sites. Summer epizootics at one site before the introduction of the flea as a biological control agent, and rabbit mortality during these, was lower than in the winter epizoo
