Abstract
1. In a factorial design of dietary treatments, male Ross broilers were given diets containing soyabean oil, hydrogenated soya‐bean oil (as a source of trans‐fatty acids) or feed fat with either 0 or 300 μg of added D‐biotin/kg. 2. Growth to 28 d was not influenced by the dietary treatments. 3. Length of tibiotarsal bones was reduced (PPP< 0.05) the concentrations of C20:4n6 and the ratios of C20:4n6/C18:2n6 in liver and growth plate cartilage. 5. Growth plate cartilage from birds affected with dyschondroplasia contained lower proportions of prostaglandin precursor fatty acids compared with normal growth plate. 6. It is speculated that an inhibition of prostaglandin biosynthesis brought about by the presence of trans‐fatty acids might contribute to the occurrence of lesions similar to dyschondroplasia.
