Abstract
CITATION: Brand, T. S., et al. 2018. Effects of varying sweet lupin dietary inclusion levels on feather classes, leather traits and meat composition of feedlot ostriches. South African Journal of Animal Science, 48(1):186-197, doi:10.4314/sajas.v48i1.20.
Highlights
The modern ostrich industry has three economically important products, namely feathers, leather and meat, which are regarded as niche products (DAFF, 2014)
The ostrich industry makes a substantial contribution to the national economy, with South Africa being regarded as the world leader in ostrich products, supplying between 75% and 85% of the global market (Brand & Jordaan, 2011; DAFF, 2014)
The aim of this study was to assess the influence of the gradual replacement of soybean oilcake meal with sweet lupin seed in the diets of feedlot ostriches on the major products, namely feather classes, leather traits and the nutritional value of the meat (Muscularis gastrocnemius)
Summary
The modern ostrich industry has three economically important products, namely feathers, leather and meat, which are regarded as niche products (DAFF, 2014). The quality and yield of these products should be taken into account to ensure the cost-efficient production of slaughter birds (Engelbrecht, 2014). 90% of the value of a slaughtered bird is derived from the skin and meat (45% each) and the remaining 10% from feathers (DAFF, 2014). The ostrich industry makes a substantial contribution to the national economy, with South Africa being regarded as the world leader in ostrich products, supplying between 75% and 85% of the global market (Brand & Jordaan, 2011; DAFF, 2014). Ostrich feathers are used as industrial and household dusters, because of their unique ability to generate static electricity, attracting dust particles (Van Zyl, 2001; DAFF, 2014).
