Özet
Bu çalışma, farklı enerji (arpa ve melaslı kuru şeker pancarı posası (KŞPP)) ve protein (soya küspesi (SK), formaldehitle muamele edilmiş soya küspesi (FMSK), pamuk tohumu küspesi (PTK)) kaynaklarının kombine edilmesinin ham besin maddelerinin sindirilme derecesi ve organizmada azot birikimi üzerine etkilerini araştırmak amacıyla yapılmıştır. Araştırmada 4 baş 1 yaşlı Morkaraman toklu kullanılmıştır. Araştırmada kullanılan yem karmalarında kuru madde, organik madde, ham protein, ham selüloz, ham yağ ve azotsuz öz maddelerin sindirilme dereceleri benzer bulunmuştur (P>0.05). Arpa+FMSK, KŞPP+FMSK, KŞPP+SK+PTK ve ticari besi yeminde, bu parametrelere ait sindirilme dereceleri sırasıyla kuru madde için %79.49, 79.03, 81.20 ve 77.91; organik madde için %80.38, 80.24, 83.37 ve 80.49; ham protein için %72.48, 70.52, 76.80 ve 74.56; ham selüloz için %67.00, 70.17, 73.87 ve 65.03; ham yağ için %89.12, 85.85, 92.22 ve 84.71; N'suz öz maddeler için ise %84.26, 86.03, 87.29 ve 85.59 olarak bulunmuştur. Azot dengesi denemesinde de, gruplar arasında bir farklılığın olmadığı, organizmada biriken azot miktarının Arpa+FMSK, KŞPP+FMSK, KŞPP+SK+PTK ve ticari besi yeminde sırasıyla 10.14 g, 7.22 g, 7.14 g ve 8.51 g olduğu ve bu değerlerin azot tüketiminin sırasıyla %60.36, 42.98, 42.84 ve 51.05'i; sindirilen azot miktarının sırasıyla %82.31, 60.93, 56.58 ve 68.46'sına karşılık geldiği belirlenmiştir. Bu çalışmada, farklı enerji ve protein kaynaklarının ham besin maddelerinin sindirilme derecesini ve organizmada azot birikimini etkilemediği; besi rasyonlarında formaldehit muamelesi üzerinde durulması gerektiği, ayrıca bu bulguların daha güvenli yorumlanabilmesi için, yedirme denemeleri ile desteklenmesi gerektiği sonucuna varılmıştır.
The objective of this study was to evaluate the effects of different energy (barley and dry sugar beet pulp (DSBP)) and protein sources (soybean meal (SBM), SBM-treated with formaldehyde (FTSBM), cotton-seed meal (CSM)) on nutrient digestibility and nitrogen .retention in sheep. In this study, 4 rumen fistulated Morkaraman rams were used.Digestibilities of dry matter, organic matter, crude protein, crude cellulose, ether extract, and N- free extract were similar (P>0.05) among animals fed different diets. Digestibilities, as percentage were 79.49, 79.03, 81,20, and 77,91 for DM; 80.38, 80,24, 83,37, and 80.49 for OM; 72.48, 70.52, 76.80, and 74.56 for CP; 67.00, 70.17, 73.87, and 65.03 for crude cellulose; 89.12, 85.85, 92.22, and 84.71 for crude oil; 84.26, 86.03, 87.29, and 85 59 for N-free extract for animals fed bar-ley+FTSBM, DSBP+FTSBM, DSBP+SBM+CSM mixtures and commercial diet, respectively.There was no significant differences on N-balance among animals fed different diets. N-retentions were 10.14, 7.22, 7.14, and 8.51 g for animals fed barley+FTSBM, DSBP+FTSBM, DSBP+SBM+CSM mixtures and commercial diet, respectively. Percentages of N retained in body and N digested were 60.36, 42,98, 42,84, and 51.05; 82,31, 60.93, 5658, and 68.46 for barley+FTSBM, DSBP+FTSBM, DSBP+SBM+CSM mixtures, and commercial diet, respectively. It was suggested from these experiments that; a) energy and protein sources didn't effect nutrient digestibility and nitrogen retention; b) formaldehyde treatment of protein source should be further studied; c) this results should be supported with fattening experiments to interpret the results safely.
