The integration of the trees as substitute of the protein source in the pig feeding isan interesting strategy in Cuba (González ,２００６) and nowadays it is a fact the use of the arboreal foliages of low cost for thefeeding of pigs ( Figueroa １９９９) . One of the viable alternatives to reduce the costs of production in the tropical regions , is thepartial inclusion of the bushes foliage in the diet of the pigs , such is the case of the mulberry ( Morus alba) . The aim of thiswork was to make a feeding test at the production conditions comparing two diets in growing‐fattening pigs , to evaluate theinclusion of the mulberry foliage ( Morus alba) in ２０％ substituting the protein source .Materials and Methods It was carrying out a feeding test at the production conditions . For this test , １６ castrated male pigs ofcommercial crossing ( YL x CC２１) w ith the initial live weight of ２８ kg and ７０ days of age . The pigs were distributed in twotreatments with ８ replications each one in a randomized complete block design . The experimental treatments were : diet I , withsugar cane molasses and NUPROVIM‐１０ ( vitamins , minerals and soybean meal concentrated ) and diet II , with sugar canemolasses , NUPROVIM‐１０ ( substituting the ２０％ of the soybean meal by mulberry foliage in dry base) . Daily the surplus ofsugar cane molasses was weighed early in the morning to control the consumption of this ingredient in the diet . Theperformance traits ( up to approximately １００ kg live weight ) were studied and the measures were analyzed by means of amathematical model of simple classification and to process the data the statistical package SAS (１９９７) was used .Results and Discussion There was not significant effect between the treatments for the final weight and the daily gain of the pigs ,although there was certain movement of the values toward an increase in the pigs that did not consume the mulberry foliage( table １) .Table 1 Per f ormance traits o f grow ing‐ f attening p igs in both treatmentsT reatmentsDiet I Diet II SE ±Initial weight , kg ２７ 趑.６３ ２９ a.３８ ０ 构.７３ 倡Daily intake ,kg / día ２ 葺.８６ ２ J.６７ ０ 谮.０８Daily gain ,g / día ６３８ P５７５ 浇１４ 6Conversion , kg of feed/ kg of gain ４ 葺.４８ ４ J.６４ ０ 谮.０９Final weight , kg １０４  .８７ ９９ a.００ ５ 谮.１３Test days ,días １２１ P１２１ 浇‐倡 P ＜ ０ .０５Conclusions It is possible to substitute up to ２０％ the protein source of the NUPROVIM‐１０ diet for growing‐fattening pigs withmulberry foliage without detriment of the productive parameters in sugar cane molasses diets .ReferencesMaga鼻a , M .A . , ２００１ .Rentabilidad y efectos de polí tica en la producción de carne de cerdo en el estado de Yucatán .
