Amaç: Bu araştırmada; toz, granül ve pelet formdaki süt sığırı karma yemlerinin ham besin madde içerikleri kimyasal ve yakın kızılötesi yansıma spektroskopi (NIRS) metodlarıyla analizleri yapılmış ve sonuçları değerlendirilmiştir.
Materyal ve Yöntem: Farklı zamanlarda her bir formdan alınmış 50 karma yem örneğinin ham besin madde analizleri her iki metotla yapılmıştır.
Araştırma Bulguları: Kuru madde değerleri hariç diğer besin madde değerleri bakımından, yem formlarının kimyasal analizi sonucundaki fark istatiksel olarak önemli çıkmamıştır. Ham protein (HP) ve ham yağ (HY) bakımından yem formları arasındaki farklar, NIRS metoduna göre analizde ise; ham protein (HP) ve ham yağ (HY) bakımından, yem formları arasındaki farklar istatistiksel olarak önemli olmadığı bulunmuştur. Oysan NIRS’a göre; KM, ham kül (HK), organik madde (OM) ve ham selüloz (HS) bakımından yem formları arasındaki farkın önemli olduğu görülmüştür (P<0.05). Kimyasal ve NIRS analizlerinin KM, OM ve HP değerleri arasında istatistiksel fark gözlenmezken, iki analiz metodunun HK, HY ve HS değerlerinde ise istatistiksel farklar görülmüştür (P<0.05).
Sonuç: Yemlerin iki farklı enerji formülüne göre kimyasal ve NIRS analiz sonuçlarına göre hesaplanmış metabolik enerji içerikleri karşılaştırılmış, sadece eşitlik 1’e göre istatiksel fark bulunmuştur (P<0.05).

Determination of the effect of feed form on nutrient values of dairy cattle mixed feeds by near-infrared reflectance spectroscopy method

Öz

Objective: In this study, Crude nutrients contents of dairy cattle mixed feeds in powder, crumble, and pellet form were analyzed by chemical and near-infrared reflectance spectroscopy (NIRS) methods, and the results of analyzes were evaluated.
Material and Methods: Crude nutrient analysis of 50 mixed feed samples taken from each form at different times, was done by both methods.
Results: As a result of the chemical analysis of the feed forms, the difference among the samples in terms of other nutrient values except for dry matter (DM) values was statistically insignificant. According to the analysis of feed forms on the NIRS method, it was found that the difference among the feed forms in terms of crude protein (CP) and ether extract (EE) values was not statistically significant. On the other hand, it was found that the differences among the feed forms in terms of the DM, crude ash (ash),organic matter (OM) and crude fiber (CF) in NIRS method were statistically significant (P<0.05). While no statistical difference was observed between DM, OM and CP values of chemical and NIRS analyzes, it was seen that the differences between two methods at ash, EE and CF values were statistically significant (P<0.05).
Conclusion: The metabolisable energy values of feeds calculated according to two different energy formulas between the chemical and NIRS methods were compared, only the value of equality 1 was found statistical difference (P<0.05).
