Peste des Petits Ruminants infection among cattle and wildlife in Northern Tanzania

We investigated peste des petits ruminants (PPR) infection in cattle and wildlife in northern Tanzania. No wildlife from protected ecosystems were seropositive. However, cattle from villages where an outbreak had occurred among small ruminants showed high PPR seropositivity, indicating that spillover infection affects cattle. Thus, cattle could be of value for PPR serosurveillance

Diagnosis and Treatment of Infectious Enteritis in Neonatal and Juvenile Ruminants.

Common causes of infectious enteritis in neonate and juvenile ruminants include viral, bacterial, and protozoal pathogens. The most common presenting sign in ruminants with infectious enteritis is diarrhea. Diagnosis of the cause of enteritis has important zoonotic and herd health implications. Severity of clinical signs with similar pathogens may differ between calves and small ruminants. Treatment of enteritis involves supportive care to correct fluid and electrolyte imbalances, provision of nutritional support for neonates, prevention and treatment of endotoxemia or sepsis, and pathogen-specific treatments when relevant and available

Religious Festivities and Marketing of Small Ruminants in Central Java – Indonesia

Indonesia is a country where small ruminants are important in religious festivities. This study analyzes small ruminant marketing opportunities on account of the Moslem feast of sacrifice, Idul Adha, in three agroecological zones in Central Java. Small ruminant marketing is classified into three categories, namely: 1) good ─ the market situation associated with the religious feast of Idul Adha; 2) risky ─usually occurring in August and September when farmers need cash to prepare the paddy fields and to pay school fees; and 3) normal ─ which is how the market situation may be described in the other parts of the year. A total of 150 farmers are visited monthly, over a period of one year, to observe their marketing strategies and the economic benefits gained from keeping small ruminants. Sheep fattening on the basis of rice bran supplementation is explored as a feasible innovation for the lowlands. Ten small ruminant markets are monitored two times corresponding to each of the three market situations. Added to this, 42 roadside sellers and 44 mosques are visited. The supply, demand, price, and weight of animals offered at the markets show a peak during Idul Adha. In the lowlands and middle zone, sheep are preferred over goats as sacrificial offerings during Idul Adha. In the uplands, goats dominate the farming system and the small ruminants’ markets. The Idul Adha market requires male ruminants of one year of age with a bodyweight of above 25 kilograms. The majority of the farmers are not able to adjust the raising of their small ruminants in time for Idul Adha, because of their small flock sizes and the fact that they have to sell their animals to meet urgent cash needs, in particular at the end of the dry season and the start of the school year. Farmers possess minimal marketing information and usually complain about the prices they receive for their merchandise. The raising of these animals is only a secondary activity on these mixed farms. Value added estimates from small ruminants per hour of family labor input are 33–38 percent below the minimum wage labor rate. The proposed innovation to introduce sheep fattening in the lowlands for Idul Adha proves to be economically viable; however, the number of sheep that households can fatten is limited.

CHARACTERIZING FORAGING PATTERNS AMONG CATTLE AND BONDED AND NON-BONDED SMALL RUMINANTS USING SPATIAL POINT PROCESS TECHNIQUES

This paper uses the technique of spatial point processes to describe the spatial patterns of freeranging cattle and small ruminants. Two mixed-species livestock groups were monitored while foraging on 410 ha of brush-infested Southern New Mexico rangeland during July and August 1988. The groups consisted of crossbred Bos taurus and Bos indicus beef cattle with white-faced sheep (Ovis aries) and mohair goats (Capra hircus). The bonded group consisted of small ruminants that had their behaviours modified through socialization with cattle to form a ‘flerd’ in which small ruminants consistently remained near cattle. Small ruminants in the non-bonded group had not been socialized with cattle. A subset of animal location data measured during the morning and afternoon over five days for both the bonded and non-bonded groups was analyzed for spatial patterns. Only data for five morning periods (7:00-8:00 a.m.) are reported because morning and afternoon spatial patterns were similar. Observed nearest neighbor distances, mean number of small ruminant near an arbitrary cow, and point-to-animal distances were compared to Monte Carlo simulations of independently and uniformly distributed animal locations. Bonded and non-bonded groups were also compared. Results suggested bonded and non-bonded groups were similar in spatial patterns of intra-specific distances for both cattle and small ruminants. However, bonding changed the repulsive relationship observed between cattle and non-bonded small ruminants stocked together to one of inter-specific attraction. Bonded small ruminants remained close to and formed inter-specific clusters with cattle. In addition, the mean number of bonded small ruminants near an arbitrary cow was consistently higher than for non-bonded small ruminants. Finally, the spatial pattern of cattle across the paddock did not differ between bonded and non-bonded groups, while bonded small ruminants tended to disperse slightly more uniformly across the paddock than did non-bonded small ruminants. These findings indicate the usefulness of spatial point processes techniques to analyze such animal location data, substantiate on a larger scale conclusions of previous, replicated studies about the effect of bonding small ruminants to cattle, and suggest utilization of paddock landscapes may be positively influenced using flerds compared to flocks and herds

Improving “Low Input” Sheep Production Systems in Europe

Sheep production in EU represents more than 100 millions heads which are mainly found in less favoured areas throughout Europe. Small ruminants are usually kept in geographical areas where other livestock or crop industries are difficult to implement

Nematode control in 'green' ruminant production systems

Collectively, nematode parasites of domestic ruminants continue to pose the greatest disease problem in grazing livestock systems worldwide, despite the powerful and extensive chemotherapeutic arsenal available for their control. The widespread development of anthelmintic resistance, particularly in nematode parasites of small ruminants, and the trend towards nonchemical (ecological, organic, green) farming of livestock has provided an impetus for the research and development of alternative parasite control methods. This article provides a brief overview of the non-chemotherapeutic options for parasite control and how they might play a role either in organic farming or in other low-input farming systems

Control of Footrot in Small Ruminants of Nepal

Footrot, a bacterial disease which attacks the feet of sheep and goats causing lameness and high levels of flock mortality, was endemic in the western districts of Nepal. As a result of the collaborative efforts between Nepalese, Australian and British scientists within ACIAR projects AS2/1991/017 and AS2/1996/021, the virulent form of this disease has been eradicated from the livestock industries of the country. The economic benefits stemming from this achievement are described and quantified in this report. Over the 1993–2022 period, ACIAR invested $A1.5 million in research designed to improve the management of footrot in Nepal. Based on levels of disease prevalence reported at the beginning of the projects and a probability of the disease spreading to other districts, disease eradication will result in a realised net present value of$A2.8 million. A benefit–cost ratio of 2.9:1 was estimated for the projects, which indicates that for each dollar invested, 2.9 dollars of project benefits will be generated. Several other countries, such as Bhutan and possibly Australia, could benefit from the footrot vaccination practices developed in these projects. Sensitivity analysis outlined in the concluding section of the report indicates that these benefits could be substantial and their inclusion would increase the value of ACIAR-supported research.Footrot, ruminants, bacterial disease, Nepal, Australia, livestock, economic benefits, net present value, benefit-cost ratio, disease eradication, Farm Management, International Development, Livestock Production/Industries, Production Economics,

Investigating the diet selection and genetic variation of small ruminants in a dryland pastoral system in South Africa

Magister Scientiae (Biodiversity and Conservation Biology) - MSc (Biodiv and Cons Biol)Small ruminants found in pastoral dryland systems face many challenges regarding constant environmental and climate changes. These variable environments are home to many pastoralists who use the natural resources to sustain their livestock. Due to the prevailing environmental changes, these pastoralists require various adaptation strategies for the survival of their small ruminants. Adaptation is vital for all pastoralists globally, especially those living in semi-arid to arid regions as these areas are badly impacted by climate change. Farming with small ruminants that are able to constantly adapt to variable environments are a long-term and low cost resource strategy for farmers in these areas. Drought is a recurring challenge that farmers in dryland systems have to cope with and small ruminants are forced to adapt to food and water available to them as drought affects their survival, reproduction and production. This is because drought affects the environment directly as rainfall has an impact on all forage and water resources found in drylands. Thus available forage and the utilisation of this resource by small ruminants is essential for sheep and goat farmers who depend on these animals for their livelihoods. This thesis sets out to establish sheep and goat breeds found in a dryland pastoral system in South Africa focussing on their genetic differences and their diet selection during a drought period. The study was carried out in the 582 634 ha Steinkopf communal area located in the semi-arid to arid region of Namaqualand in South Africa. The dominant land use in this area is livestock farming where farmers utilise two biomes for grazing. Using mitochondrial DNA, genetic differences were investigated in small ruminants found in Steinkopf. The small ruminants that were studied were the Boer goats, Swakara sheep (Karakul) and cross-bred sheep. These were the most commonly farmed small ruminants in this area. Genetic differences and diversity found within the small ruminants in this area supports their ability to adapt to drought and changing environments. Diet selection of these small ruminants were assessed using direct forage observation during this drought period in both the Succulent and Nama Karoo biomes. Findings of the study indicate that small ruminants during a drought period will largely forage on what is available to them. Boer goats changed their diets from browser to grazers in the different biomes while sheep remained grazers in both biomes. This suggests that these animals are well adapted to changing forage availability and will adjust their feeding behaviours accordingly. Succulent plant species were utilised by all small ruminants and this can be regarded as new knowledge for small ruminants in dryland systems. Succulent species play a role in the diets of small ruminants in the Steinkopf rangeland and these animals have adapted traits that allow them to eat plants that contain high levels of phenolics and tannins, which show their high adaptability to this area. This study also revealed that indigenous and locally bred sheep in this area are crucial resources for livestock farming in this area. Swakara sheep in this area showed a low level of genetic variation while cross-bred sheep and the Boer goat had significant variation. With a long tradition of breeding small ruminants in the Steinkopf communal area that suit changing conditions, livestock keepers have accumulated detailed knowledge of their animals. Recommendations from this study were to do further studies regarding genetic variation within the cross-bred sheep as this information will be useful for breeding programs in dryland areas and it will add to the small ruminant genetics in South Africa. Because this study was conducted in a drought period, I recommend that diet selection should be observed during a regular wet and dry period as this would indicate how these animals adapt to what forage is available to them. These studies can act as management strategies for herders as it can provide information on how to use the natural resources sustainably
