    Fallow deer in southern Africa: a potential meat source or is it just an invasive species?
    (Colorado State University. Libraries, 2016-09) Hoffman, Louw, author; International Wildlife Ranching Symposium, publisher
    Where Fallow deer (Dama spp.) were once almost extinct, they have now become one of the most widespread wild ungulate species in the world. In South Africa, this species has also been introduced and is now abundant in the country and could contribute to food security within Africa. However, conservation authorities tend to view this ungulate species as an invasive species whilst game farmers see it as a valuable contributor to farm income: as a hunted trophy or as a source of quality and nutritious meat. Surprisingly, very little is known about its production potential and meat quality in South Africa. Fallow deer have been farmed successfully innumerous countries with the industry in New Zealand being the most prominent. All indication are that this species has adapted well to South African conditions and are highly productive. The meat yield and quality of this species is of the highest standard when adequate harvesting procedures are followed. The fatty acid profile of this species is also beneficial for human consumption. However, antidotal information has it that the meat from stags during the rut has a taint to it: the cause of this has not yet been quantified. Initial results (to be discussed) indicate that the meat quality of this species is of the highest standard typical of wild game animals. However, the distribution of this species needs to be quantified so that strategies can be developed to develop its potential as a sustainable protein source fit for human consumption. The ecological impact of this species also needs to be quantified so that, if required, adequate legislation can be developed to either curb or grow the potential deer farming industry.

    Zebra: more than just stripes
    (Colorado State University. Libraries, 2016-09) Hoffman, Louw, author; International Wildlife Ranching Symposium, publisher
    Zebra (Equus quagga burchellii) are growing in number in southern Africa, with the meat from surplus animals holding potential to contribute to food security and economic stability. Despite being consumed locally and globally, little information exists on the composition of zebra meat. This study aimed to determine the proximate composition of zebra meat as well as the fatty acid composition of the intramuscular (IMF) and subcutaneous (SCF) fat. Zebra longissimus lumborum muscle was shown to have a high mean protein content (22.29 g per 100g) and low mean fat content (1.47 g per 100 g). High proportions of polyunsaturated fatty acids (PUFAs) were found in the IMF (41.15%) and SCF (37.71%), mainly comprising -linolenic (C18:3n-3) and linoleic (C18:2n-6) acids. Furthermore, the IMF and SCF had favourable PUFA/saturated fatty acid ratios (>0.4) and omega-6/omega-3 ratios (<4), indicating that both components are healthy lipid food sources. This study has shed new light on the nutritional value of zebra meat, which will not only be important for food product labelling, nutritional education and incorporation into food composition databases, but will also be indispensable for marketing and export purposes.
