The effects of dietary energy and protein concentrations on ostrich skin quality (2006)

Cloete, SWP, Van Schalkwyk, SJ, Brand, TS, Hoffman, LC, Nel, CJ

The effects were investigated of energy and protein concentrations (with associated amino acid concentrations) in ostrich diets on leather quality of the skins of 50 ostriches. Energy concentrations...

The influence of stocking rate and male:female ratio on the production of breeding ostriches (Struthio camelus spp.) under commercial farming conditions (2004)

Lambrechts, H, Swart, D, Cloete, SWP, Greyling, JPC, Van Schalkwyk, SJ

The study provides information on the reproductive performance of ostriches maintained at different stocking rates and male:female (M:F) ratios under intensive commercial conditions in the Little...

Is genetic selection for skin nodule traits of ostriches feasible? (2004)

Meyer, A, Cloete, SWP, Van Wyk, JB, Van Schalkwyk, SJ

Preliminary genetic parameters for nodule traits of ostrich skins were estimated to examine whether genetic improvement of skin quality is feasible. Average nodule size and density per...

Effect of age on leather and skin traits of slaughter ostriches (2004)

Cloete, SWP, Van Schalkwyk, SJ, Hoffman, LC, Meyer, A

Little is known about the factors affecting leather and skin traits in ostriches. The effect of age on physical skin traits of slaughter ostriches was consequently investigated. Forty skins...
