Besi Sığırı Rasyonlarında Tamamlayıcı Yem Olarak Farklı Şekillerde İşlenmiş Arpa ve Mısır Kullanımının Performans, Bazı Biyokimyasal Parametreler ile Serum Laktat ve Bikarbonat Düzeyi Üzerine Etkileri

Araştırma, besi sığırı rasyonlarına tamamlayıcı yem olarak ilave edilen arpa (öğütülmüş) ve farklı işlemlerden geçirilmiş mısırın (öğütülmüş, peletlenmiş ve flake) canlı ağırlık artışı, yem tüketimi, yemden yararlanma oranı, bazı biyokimyasal parametreler ile serum laktat ve bikarbonat seviyeleri üzerine etkilerinin belirlenmesi amacıyla yürütülmüştür. Araştırmada 13-14 aylık yaşta ve ortalama 324.9±1.36 kg canlı ağırlıkta, 20 adet Holştayn x Montofon melezi besi sığırı 4 gruba eşit olarak dağıtılmıştır. Deneme grupları, bazal rasyonlara metabolik enerji içeriği eşit olacak şekilde öğütülmüş arpa, öğütülmüş mısır, pelet mısır ve flake mısır ilave edilerek oluşturulmuştur. Araştırma sonunda performans verileri, kan parametreleri ve serum laktat ve bikarbonat düzeyleri bakımından gruplar arasında farklılık istatistiki olarak önemli bulunmamıştır (P>0.05). Ekonomik olması durumunda farklı işlemlerden geçirilmiş mısırın besi büyütme dönemi rasyonlarında tamamlayıcı yem olarak kullanılabileceği sonucuna varılmıştır.

Effects of processed barley and corn supplementation on feedlot cattle diets on performance, some biochemical parameters and lactate and bicarbonate levels of blood

The aim of the research was to evaluate a possibility effect of supplementing barley (ground) and treated corn (ground, pelleted and flake) on the body weight gain, feed consumption, feed efficiency, and some blood biochemical parameters, serum lactate and bicarbonate levels of the beef catle. Twenty Holstein x Brown Swiss yearling beef bulls (324.9±1.36 kg) averaging 13-14 months of age were randomly assigned to four groups. The treatments were ground barley, ground corn, pelleted corn and steam-flaked corn grain, respectively, substituting basal TMR according to the metabolisable energy content. At the end of the study, experimental treatments did not affect to performance, blood biochemical parameters, serum lactate and bicarbonate levels. It is concluded that proccessed corn could be used in fattening beef cattle in growth period if it is economical.
