Abstract:

Cottonseed meal is a kind of high quality plant protein follows only soybean meal.The high content of protein and abundance of amino acid in cottonseed meal have attracted much attention.However,the existing of some anti-nutritional compounds in cottonseed meal limited its application in feed industry.An optional way to eliminate those negative effects is fermenting the cottonseed meal with microorganism.It has been demonstrated that after fermenting,the anti-nutritional factors in cottonseed meal decreased significantly while some beneficial ingredients increased (e.g.small peptides,digestive enzymes,organic acids and probiotics),and eventually increase the nutritional value of the cottonseed meal.The fermented cottonseed meal has been widely used in the feeding.The authors review the nutritional value of fermented cottonseed meal and its application in animal production.Using fermented cottonseed meal instead of soybean in the diets of growing pigs by 5% to 10%,feed intake,daily gain and feed meat ratio are not significantly influenced,and the cost of feed can be reduced.Adding the fermented cottonseed meal in the diets of chicken by 5% to 15%,can improve the immunity of chickens,reduce morbidity,save the cost of medication,and improve the quality of egg and meat.The fermented cottonseed meal can also be used as ruminant animal feed supplement protein in raw materials,it can promote the growth and reproduction of microorganisms in rumen,increase the ruminant animal feed utilization rate.The fermented cottonseed meal can be used instead of fish meal and soybean meal in aquatic feed,not only can reduce the cost of feed and feed coefficient,but also improve water quality,increase the aquatic animal digestive enzyme content,so as to improve the rate of digestion and absorption of nutrients.
