    Factors influencing off-take rates of smallholder sheep farming systems in the Western Cape Provinve of South Africa
    (South African Society of Agricultural Extension, 2019) Molotsi, A. H.; Oosting, S.; Cloete, S. W. P.; Dzama, K.
    The purpose of this study was to determine off-take rates in smallholder sheep farming systems in the Western Cape province of South Africa. A purposeful sampling technique was used where smallholder farmers were selected based on certain criteria. The criterion set out was that farmers must own between five and 100 sheep. Interviews were conducted with 72 smallholder farmers in three districts, namely the West Coast, Karoo and Eden. General information on the socio-economic status of the farmers was obtained through semi-structured questionnaires. The main sources of income for the Karoo farmers was livestock (46%) and crops for Eden (32%). Farmers in the West Coast area mostly relied on salaries (43%), thus off-farm income. The Karoo district sold a higher average number of lambs per year (41 ± 8.8), with West Coast and Eden selling the same average number of lambs per year at 7 ± 2.2 and 7 ± 2.6 respectively. Overall, the income derived from livestock is low and not economically sustainable. Therefore, different strategies (such as access to market, financial assistance, improved animal nutrition and health management, as well as sound breeding plans) should be employed to assist smallholder livestock farmers to increase off-take rates.

    A survey of the prevalence of blowfly strike and the control measures used in the Ruens area of the Western Cape Province of South Africa
    (AOSIS, 2011) Scholtz, A. J.; Cloete, S. W. P.; Du Toit, E.; Van Wyk, J. B.; Van der Linde, T. C. de K.
    Blowfly strike and the methods used to combat blowfly strike were recorded on 33 properties in the Rûens area of South Africa during 2003/2004. Data were recorded on Merino and Dohne Merino hoggets (n = 4951) with at least 3 months' wool growth. The following data were captured: presence or absence of strike, site of the strike (body or breech), presence or absence of dermatophilosis as well as subjective scores for wool quality and wool colour. Control measures recorded include: chemical treatment (preventative and spot treatment), crutching, mulesing and the use of the Lucitrap® system. Blowfly strike was not significantly influenced by gender or breed. Hoggets suffering from dermatophilosis were more likely to be struck, compared with contemporaries not suffering from the skin disorder (0.057 vs 0.027; P < 0.05). Merino hoggets generally had higher scores than their Dohne Merino contemporaries for wool quality (32.6 vs 27.4; P<0.05) and wool colour (29.0 vs 27.2; P<0.05). There was an indication that the Lucitrap® system may have reduced flystrike, but the effect was not statistically significant (P = 0.19 for overall strikes and P = 0.12 for body strike). The Mules operation benefited overall flystrike (0.013 vs 0.110; P < 0.05); mainly through an effect on breech strike (0.010 vs 0.109; P < 0.05). The proportion of fly strikes increased with wool length, and declined with an increase in farm size in wool colour score. None of the ethically acceptable control measures assessed could substantially reduce blowfly strike on their own, and an integrated pest management programme was proposed.
