The main factor for the animal performance is the feed intake , which demands farther studies abouthow to feed better of the ruminants . This work aimed to assess the nutrients consumption for the Ile‐de‐France lambs fed upwith corn silage or sugar cane as roughage into two roughage :concentrate ratio .Materials and methods １６ Ile‐de‐France males lambs were used , distributed in four treatments as such : ６０％ CS :４０％ C‐６０％ ofcorn silage plus ４０％ of concentrate ; ６０％ SC :４０％ C‐６０％ of sugar cane plus ４０％ concentrate ; ４０％ CS :６０％ C‐４０％ of cornsilage plus ６０％ of concentrate ; and ４０％ SC :６０％ C‐４０％ of sugar cane plus ６０％ of concentrate . The forage variety of sugarcane used in this experiment was the IAC‐８６２４８０ . The diets were isoproteic and isoenergetic with １９ .７０％ of crude protein and２ .５０ Mcal/ kg /DM of metabolizable energy . Samples of feces and urine offered the contents of dry matter ( DM ) , organicmatter ( OM ) , mineral matter ( MM ) , crude protein ( CP) , ethereal extract ( EE) , neutral detergent fiber ( NDF) and aciddetergent fiber ( ADF) . The total carbohydrates ( TCHO) were obtained by the equation : １００‐( ％ CP ＋ ％ EE ＋ ％ MM ) andnon‐structural carbohydrates ( NSC) , via the difference between the TCHO and NDF ( Sniffen et al . , １９９２) . The consumptionof each nutrient was calculated by the difference between the intaken nutrient and the quantity of nutrient present in the feces ,duly expressed in the DM . The data were submitted to a variance analysis and compared to the Tukey test at ５％ probabilitybasis .Results There was no difference ( P ＞ ０畅０５) regarding the intakes of DM , OM , CP , TCHO and NSC . However , the intakes ofMM and EE showed to be minors in the treatment with ６０％ SC :４０％ C , from ３７ .５１g e ９ .５２g / animal/ day , respectively ,capable of explain by the low content of these in the sugar cane ( Table １) . The consumption of NDF and ADF were greater forthe treatment with ６０％ CS :４０％ C , from ３５８ .９ and １６３ .２g / animal/ day , probably due to a major quantity of corn silage in thistreatment . At this work , the greatest content of NDF was found in the treatment with ６０％ CS :４０％ C , which resulted in amajor consumption of NDF .Table 1 Intakes o f dry matter ( DM I ) , organic matter ( OM I ) , mineral matter ( MM I ) , crude p rotein ( CPI ) , etherealex tract (EEI ) , neutral detergent f iber ( NDFI ) , acid detergent f iber ( A DFI ) , total carbohydrates ( TCHOI ) and non‐structural carbohydrates ( NSCI ) f or the I le‐de‐France lambs f ed up w ith diets containing corn silage or sugar cane f oragev ariety .Variable( g / animal / day )T reatmenta６０％ CS ∶ ４０％ C ６０％ SC ∶ ４０％ C ４０％ CS ∶ ６０％ C ４０％ SC ∶ ６０％ C VC ( ％ )DMI １１５７ {.４０ ８３６ ^.４０ １１６０ j.６０ １０１６ a.００ １２ 侣.４５OMI １０９３ {.００ ７９８ ^.８０ １０９５ j.５０ ９６２ M.５０ １２ 侣.５０MMI ６４ ?.４２a ３７ 4.５１b ６５ ..０２a ５３  .４９ab １２ 侣.００CPI ２１９ f.３７ １６５ ^.５１ ２３８ U.７７ ２０９ M.０６ １３ 侣.４８EEI ３６ ?.６０a ９ $.５２c ３６ ..７５a ２０ #.９７b ９ �.９１NDFI ３５８ T.９１a １８９ H.１６b ２６２ @.３７b １８６ 7.６１b １２ 侣.３１ADFI １６３ T.２０a １０２ H.５２b １２６ -.６１ab ９１ #.２６b １２ 侣.７６TCHOI ８３７ f.０３ ６２３ ^.８２ ８２０ U.０１ ７３２ M.４９ １２ 侣.４９NSCI ４７８ f.１１ ４３４ ^.６６ ５５７ U.６５ ５４５ M.８８ １３ 侣.４２Averages followed by the same letter in the line do not differ by the Tukey test ( P ＞ ０ .０５ ) .a６０％ CS :４０％ C‐６０％ of corn silage plus ４０％ of concentrate ; ６０％ SC :４０％ C‐６０％ of sugar cane plus ４０％ of concentrate ; ４０％ CS :６０％ C‐４０％ of corn silage plus６０％ of concentrate ; ４０％ SC :６０％ C‐４０％ of sugar cane plus ６０％ of concentrate .Conclusions The sugar cane forage variety in any proportion studied , did not affect the crude protein and dry matter intakes , themain nutrients for the animal performance .
