OZET Insan yiyecegine paralelolarak hayiian yem/erinin de yeterliduzeyde uretilememesi hem ulkemizde hem de' tum dunyada, kar.simiza cikan en omemli bir sorundur.

The Possibilities of Using Tomato Pomace as Roughage in Ruminant Rations SUMMARY A digestion trial was eonducted in order to determine the feed value of tomato pomace in lamb rations. The samples of tomato pomace were analyzed, revea1:ed that on a dry matter. basis, tomato pomaee contain more crude protein (17,47 %) 'and as much or more mineral matter as good'quality pasture hay. The digestibility and nitrogen retention were determined usIng two lambs for eacb ration: The rations were fed to two 1ambs each were alotted randomly to the cages. Eaeh lainb was fed 1300 gr. ration daily. The' rations were: i. BOO gr. good quality pasture hay 2. 1000 gr. good quality pasture hay plus 300 gr. barley and 3. JOOO gr. tomato pomace p1us . 300 gr. barley. The difference method was used in the detel1mination of the digestibiiity of barley. Dry matter digestion of tomato pomace ration (59,46 %) was 1ess than the good quality pasture hay ration (59,99' %). Organie matter digestion of good quality pasture of hay was 3,2 % higher than the tomato pomace 171 vitro dry matter digestion of good quality pasture hay (5Q,75 %) and tomato pomace (53,09 %) gave paral· lel results to in vivo organic matter digestions . of good quality pasture hayand .tomato pomace. The nitrogen retention of the good quality pasture hay ration lambs (+ 1,57 N/day)'was less than the tomato pomace ration lambs (+ 10,27 gr. N/day) which was due to the high crude protein content of the tomato pomace. However the crude protein digestion 1ev.els were 58,48 % for the good quality pasture hay ration and 56,64 %for the tomato pomace ration respectively. The results obtained from the experiment and analyses revealed that . the tomato pomace could be used as roughage or roughage portion in ruminant rations but this preliminary results need further investigations.
