Abstract

A 84-d growth trial was conducted to determine the efficacy of methionine hydroxy analog (MHA) as a source of metabolizable methionine. A basal diet of 44% corn cobs and 44% sorghum {Sorghum bicolar L.) silage with 12% supplement (DM basis) was fed to 59 individually-fed crossbred steers (267 ±8 kg) for 84-d. Steers were supplemented with urea, meat and bone meal (MBM), or MBM plus MHA. Six treatments of trial were urea- control; MBM; MBM+four levels of MHA. Methionine hydroxy analog was added to MBM at gradually increasing levels (2.8, 5.7, 8.5 and 17 g/head/d). During 84-d period, average daily gain did not differ among treatment group (P>.05). Plasma methionine levels for MBM +MHA treatments were not numerically higher than the urea control groups. Feed intake of treatments was not significantly different among treatment groups (P>.05). These data indicate that MHA used in this study did not escape rumen degradation to provide sufficient metabolizable methionine for growing calves.

Özet

Metionin hidroksi analoğunun (MHA) metabolik metionin kaynağı olarak kullanım etkinliğini araştırmak için 84 günlük bir büyüme denemesi yapılmıştır. Araştırmada, ortalama canlı ağırlığı 267=8 kg olan 59 adet melez besi danası ferdi olarak, kuru madde bazında % 44 mısır koçanı, % 44 sorgum silajı ve rasyonun %12'sini oluşturan 6 farklı destekleme yemi ile bireysel olarak beslenmişlerdir. Destekleme karışımları üre, et-kemik unu (EKU), ve EKU'na dört farklı seviyede MHA ilavesinin yer aldığı karışımlardan oluşturulmuştur. Metionin hidroksi analoğu 2.8, 5.7, 8.5 ve 17 gr/gün/dana seviyelerinde verilmiştir. Deneme sonunda grupların günlük canlı ağırlık artışı ve yem tüketimleri muamelelerden önemli derecede etkilenmemiştir (P>0.05). Et-kemik unu-rMHA deneme gruplarının plasma methionine seviyeleri üreli (kontrol) gruptan rakamsal olarak yüksek bulunmamıştır. Elde edilen veriler, bu çalışmada kullanılan MHA'in rumendeki parçalanmayı geçemeyerek büyüme çağındaki hayvanların metabolik metionin ihtiyacını karşılıyamadığını göstermiştir.
