Abstract:

China is a big country of animal husbandry with a large demand for feed resources,but facing with serious problems such as insufficient supply.Unconventional feed resources are of great significance to the healthy and sustainable development of Yellow-feathered broilers industry.In the current review,research progresses on the effect of non-conventional feeds on growth performance and meat quality of Yellow-feathered broilers in recent decade are presented,including non-conventional energy feeds,non-conventional protein feeds and some other non-conventional feeds.The non-conventional energy feeds include rice bran,feed rice,cassava and cassava residues.Non-conventional protein feeds include cottonseed meal,rapeseed meal,distillers dried grains with soluble (DDGS) and peanut meal.Some other non-conventional feeds are mulberry leaf powder,Moringa oleifera powder,mushroom residues,fermented monosodium glutamate (MSG) residues and pomelo peel powder. etc.Toxin or some other anti-nutritional factors contained in non-conventional feeds are showed specially.In addition,advantages and disadvantages of non-conventional energy/protein feeds compared to corn and meal are demonstrated.Proper amount of nutritional characteristics and contents of non-conventional feeds,when and how long used in the diet of Yellow-feathered broilers are given out.At last,some problems existing in the utilization of non-conventional feed resources are pointed out,and some solutions and further research directions are proposed.On the basis of this review,theoretical and technical supports for the application of these non-conventional feeds in Yellow-feathered broilers are presented to further promote healthy sustainable development of Yellow-feathered broilers industry.

Key words: Yellow-feathered broilers; non-conventional feed; anti-nutritional factor; growth performance; meat quality
