Yem formunun yakın kızılötesi yansıma spektroskopi metoduyla süt sığırı karma yemlerinin besin madde değerlerine etkisinin belirlenmesi

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

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

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
