          Abstract

          The study was conducted to determine cattle production and management practices of developing cattle farmers in two selected districts (Amathole and Chris Hani) in the Eastern Cape Province of South Africa. The study mainly focused on beef cattle farmers that are farming on leased or private land. From both districts, 60 respondents (30 per district) were interviewed using structured questionnaires. Results showed that 33% of the study sample had low levels of education while only 15% (n=10) had tertiary education qualifications. Cattle management activities were performed by almost all the respondents except deworming which was done by only 33%. The respondents were mostly vaccinating for diseases such as Black quarter (42%), Redwater (40%), and Anthrax (30%). The assessed farmers were controlling parasites with many different methods, however, pour on was found to be the most frequently used method (52%), followed by plunge dipping (33%) and hand spray (32%). There were farmers that planted cultivated pastures (35%) and some that were also using supplements (licks) for their herds (77%). As bush encroachments were not a problem in some farms, most farmers were not taking any actions, but 24% were using fires when reducing moribund. Breeding monitoring activities (birth observation, pregnant test and bull futility testing) were conducted by the respondents (78%, 15% and 12% respectively). It is recommended that agricultural extension play an imperative role in linking possible role players and farmers.

          Field studies and cost-effectiveness analysis of vaccination with Gavac against the cattle tick Boophilus microplus.

          The control of tick infestations and the transmission of tick-borne diseases remains a challenge for the cattle industry in tropical and subtropical areas of the world. Traditional control methods have been only partially successful and the parasites continue to result in significant losses for the cattle industry. Recently, vaccines containing the recombinant Boophilus microplus gut antigen Bm86 have been developed. These vaccines have been shown to control tick infestations in the field. However, extensive field studies investigating the efficacy and cost-effectiveness of vaccination have not been reported and are needed to appraise the effect of this new approach for tick control. Here is reported the results of the application of Gavac in a field trial including more than 260,000 animals in Cuba. In this study the correlation between the antibody response to vaccination and the effect on ticks fertility is determined. Physiological status of the animals was found to affect the primary response to vaccination but not the antibody titers after revaccination. A cost-effectiveness analysis showed a 60% reduction in the number acaricide treatments, together with the control of tick infestations and transmission of babesiosis, which resulted in savings of $23.4 animal-1 year-1. These results clearly demonstrate the advantage of vaccination and support the application of Gavac for tick control.

              Cattle-rangeland management practices and perceptions of pastoralists towards rangeland degradation in the Borana zone of southern Ethiopia.

              A survey was conducted in the Borana pastoral areas of southern Ethiopia to assess current livestock production systems, rangeland management practices and the perceptions of the pastoralists towards rangeland degradation. This information is considered vital to future pastoral development planning and interventions. Data were collected from a total of 20 villages that were identified from 5 peasant associations, namely Did Yabello, Moyatte, Did Harra, Dubuluk and Melbana. The average household size in the study area was 7.23. The majority of the pastoralists relied on both livestock and crop farming. The average livestock holding per household was 14 cattle, 10 goats, 6 sheep and 2 camels. Livestock holdings, with the exception of camels, has shown a declining trend over time. The two most important traditional rangeland management strategies adopted by the pastoralists included burning and mobility, but since 1974/75 burning has no longer been practised. With regard to mobility, the livestock herding falls in two categories, namely: home based and satellite herding. The former involves the herding of milking cows, calves and immature animals ( 2 years) further away from the encampments. Based on the pastoralists' perceptions, the major constraints on livestock production in descending order, were recurrent drought, feed and water scarcity, animal diseases, predators and communal land ownership. All the respondents considered the condition of the rangelands to have declined dramatically over time. In the past most development policies were based on equilibrium theories that opposed the communal use of the rangelands and traditional range management practices. The way in which the pastoral system affects the rangeland ecosystem functioning is contentious to this theory and the 'tragedy of the commons'. There was also a perceived problem of bush encroachment and the ban on traditional burning practices and recurrent droughts were seen as aggravating factors to this invasion process. The increasing practice of crop cultivation on the rangelands was identified as a serious threat to future livestock production and traditional resource management practices. Suggestions for possible interventions to improve the productivity and sustainable use of these rangelands are made.
