Süt sığırlarında magnezyum oksit kullanımı

Bu çalışmanın amacı, süt sığırı rasyonlarına katılan magnezyum oksitin (MgO) süt verimine, yemden yararlanma oranına, rumen, dışkı, idrar, süt pHlarına ve süt yağına etkisini değerlendirmektir. Çalışmanın birinci aşamasında laktasyonun ilk 70 günündeki süt sığırı rasyonlarına ilave edilen MgO (100 gr/baş/gün) uygulaması; süt verimini, yemden yararlanmayı, rumen, dışkı, idrar ve süt pHsını yükseltmiş (P < 0.0001), ancak süt yağını düşürmüştür (P < 0.0001). Çalışmanın ikinci aşamasında, süt verimi ve yemden yararlanma rasyona 100 gr MgOe dikalsiyum fosfat (DCP) ilavesi (40 ve 80 gr) ile birlikte artmış (P < 0.0001), süt yağı ise azalmıştır (P < 0.0001). Rasyona katılan MgO ve DCP, dışkı, idrar, rumen ve süt pHsını yükseltmiştir (P < 0.0001). Çalışma sonuçlarına göre, erken laktasyondaki süt ineği rasyonlarına katılan 100 gr MgO ve 80 gram DCP süt verimini ve yemden yararlanma oranını artırmış, süt yağını düşürmüştür. Laktasyonun ilk 70 gününde süt ineklerine normal rasyona ilave olarak, 100 gr MgO ve 80 gr DCP katılması önerilmektedir.

Use of magnesium oxide in dairy cattle

ABSTRACT The purpose of this study was to investigate the effects of supplemental magnesium oxide (MgO) in milk yield, milk fat, and pH of milk, urine, feces, and rumen in lactating dairy cows. In the first stage of the study, where 100 gr of MgO was added to the ration (100 gr MgO/head/day), milk yield, feed efficiency, pH of rumen, feces, urine and milk increased (P
