Abstract

Abstract: The common nutritional ingredients of coffee and its by-products were measured to make the evaluation of feeding values and to evaluate the feeding values of coffee and its by-products as livestock feed to promote the development of coffee residues. The results showed that: The crude protein contents of coffee shell, coffee cherry and coffee bean ranged from 9.54-13.54% without obvious differences (P>0.05), of which were significantly higher than that of spent coffee grounds (SCG) nearly and forage quality. The ether extract (EE) contents of coffee bean was highest, ranging from 4.94-6.86%, followed by coffee cherry with a value of 3.26%, and the counterpart of SCG was lowest (P<0.01). The contents of CF, NDF, ADF and ADL of SCG were significantly higher than those of coffee shell, coffee cherry and coffee bean (P<0.01), of which the corresponding values of coffee shell were lowest showing the optimal feeding value. Among the material types, the Ash and P contents were the minimum for SCG, with a middle value of Ca content of 0.33%. For six types of materials, RFVs and GIs were maximum for coffee shell, followed coffee cherry and coffee bean, while the worst was belonged to SCG. Except slight differences between coffee beans, the values of RFVs and GIs successively ranked in coffee shell-1＞coffee shall-2＞coffee cherry＞coffee bean-1 (washed)＞coffee bean-2 (unwashed)＞spent coffee grounds, with the RFVs of 420.74, 260.09, 161.15, 117.97, 110.94, 34.43, and GIs of 182.76, 105.55, 34.44, 17.03, 18.95 and 0.55, respectively. The values of DMI and NEL were maximum for coffee shell, followed by coffee cherry and coffee bean while the counterparts of SCG were minimum, showing a skipping differences between the feeding values from four materials (P<0.01).Therefore, coffee shell and coffee cherry possessed higher feeding values while SCG had a little worth with lower feeding value less than straw. It was suggested that coffee residues could be turned into feedstuff by the process of silage or mixed silage.
