          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.
