Abstract

Sunflower meal (SFM) has the potential to be a major feed ingredient for poultry in many countries not suitable for extensive soyabean cultivation. SFM is a good source of protein with amino acid availabilities similar to those of soyabean meal (SBM), and much higher than those in cottonseed or rapeseed meals. Its lysine content is relatively low but this can be resolved with supplemental lysine. Fibre content should be decreased to a minimum by dehulling during processing of the sunflower seed for oil extraction. Fibre < 12%) can still cause bulky feed at higher inclusion rates (< 30%), and as a result dietary nutrient dilution (particularly in broiler diets) may occur. Nevertheless, pelleting the diet can help overcome the bulkiness and thereby lead to improved growth and feed efficiency. Another characteristic of SFM is that it does not have anti-nutritional factors such as those found in soyabean, cottonseed and rapeseed meals. Enzyme supplementation to SFM-based diets in different types of poultry species need further study. The ingredient can successfully be included in layer, broiler and waterfowl diets to replace 50–100% of soyabean meal, depending on the type of diet and the nature of the other ingredients.
