SÜTE KATILAN MANNAN-OLİGOSAKKARİT VE KROMUN BUZAĞILARDA PERFORMANSA VE BAZI KAN PARAMETRELERİNE ETKİSİ

Öz

Bu çalışmanın amacı buzağılara süt ile birlikteverilen mannanoligosakkarit (MOS) ve kromun (Cr)buzağı performansına etkisinin değerlendirilmesidir.Çalışmada 3 grup halinde, her grupta 20 adet olmaküzere toplam 60 adet yeni doğmuş Holstein buzağıkullanılmıştır. Buzağılara doğduktan sonra 3 günkolostrum buzağıların canlı ağırlıkları alınarak sütten kesilinceyekadar kaliteli yonca ve buzağı başlangıç yemi hergrupta olmak üzere süt ya da MOS (6 gr/gün/baş) yada MOS+Cr (6 gr MOS/gün/baş + 0.5 ppm Cr/gün/baş) ilaveli süt tüketmeleri sağlanmıştır. Gruplarınbaşlangıç canlı ağırlıkları arasında ve çalışma sonucanlı ağırlıkları arasında önemli fark bulunmamıştır (P> 0.39). Kombinasyon şeklinde buzağılara verilenMOS ve Cr’nin daha büyük kalça yüksekliği (P = 0.01),çapraz vücut uzunluğu (P = 0.009) ve kalça ölçüsü (P= 0.001) sağladığı belirlenmiştir. Göğüs ölçüleribuzağı grupları arasında farklılık göstermemiştir (P >0.05). Serum kalsiyum ve kolestrol düzeyleri hem MOSuygulanan hem de MOS+Cr uygulanan grupta yüksekbulunmuştur (P = 0.001). Glikoz ve protein düzeyigruplar arasında farklı bulunmamıştır (P > 0.05). Tekbaşına MOS’un etkisi olmamakla birlikte, krom ilekombine kullanıldığında performans artışı ve kanparametreleri bakımından olumlu sonuçlar alınmıştır.Çalışma sonuçlarına göre yeni doğan buzağılarınsütlerine MOS ve kromun, sırasıyla 6 gr/gün ve 0.5ppm/gün düzeyinde kombine şekilde ilave edilmelerininuygun olacağı düşünülmüştür

Effects of Mannan Oligosaccharides and Chromium on Performance and Some Blood Levels Parameter of Calves Consuming Milk

Öz

The objective of the study was toinvestigate the effects of mannanoligosaccharides(MOS) and chromium (Cr) on performance ofcalves consuming milk. A total of 60 Holstein calveswere fed colostrums on first 3 days after deliveryand assigned into 3 groups 20 per group, namelycontrol (no supplement, only milk), milk plus MOS(6 g/day/head)), and milk plus MOS plus Cr (0.5ppm/day/head) along with alfalfa and starter diet inall groups until weaning. Body weight changeswere similar between groups (Pcombination of MOS and Cr in milk provided moregrowth in terms of hip heights (P=0.01), bodylength (P=0.009), and hip widths (P=0.001).Heart girths were similar among groups (P>0.05).Both serum Ca and cholesterol concentrations weregreater when either MOS alone (P=0.001) orMOS plus Cr was offered to the calves (P=0.002).Serum glucose and protein concentrations remainedunchanged with treatments (P>0.05). AlthoughMOS itself is not effective, when it is combined withCr, the performance improved. New born calvescould be supplemented with MOS at 6 g/day with Crat 0.5 ppm for a better growth performance
