Abstract

This experiment was conducted to determine the effect of lglkg viable yeast culture (Thepax, 12xlO9 Saccharomyces cereviciae/g) added to the concentrate on the fattening performance and some rumen metabolites of steers. Sixteen Holstein and sixteen Limousin X Jersey crosbreed (F1) steers aged 12-18 months were used. The experimental period lasted 70 days. The steers were divided into two control groups (Holstein control group -Hk- and Limousin X Jersey crosbreed control group -L x Jk-) and two treatment groups (Holstein treatment group -Hd- and Limousin X Jersey crosbreed treatment group -LxJd-) each containing 8 steers. The average daily live weight gains in the groups ofHk, Hd, LxJk and LxJd during experiment were 1.571, 1.462, 1.383 and 1.412 kg, respectively. Total feed dry matter consumption per kg of live weight gain were found as 6.01, 6.46, 6.93 and 6.69 kg, respectively. There were no significant differences among groups and strains in terms of pH, ammonia, total volatile fatty acid concentrations and total buffer capacity of rumen fluid at 60 th. days of investigation. It is concluded that dietary inclusion of viable yeast culture had not any effect on fattening performance and rumen metabolites in steers fed concentrate-based rations.

Özet

Bu araştırma, besi sığın konsantre yemlerine 1 g/kg düzeyinde katılan canlı maya kültürünün (Thepax, 12xlO9 Saccharomyces cerevisiae/g) besi performansı ile bazı rumen metabolitleri üzerine etkisini incelemek amacıyla yapıldı. Çalışmada, 12-18 aylık 16'şar baş erkek Holştayn ile Limozin X Jersey melezi (Fİ) besi sığırı kullanıldı. Yetmiş gün sürdürülen araştırma, her birinde 8 baş besi sığın bulunan dört grup -Holştayn kontrol Hk), Holştayn deneme (Hd), Limozin X Jersey melezi kontrol (LxJk) ve Limuzin X Jersey melezi deneme (LxJd)-halinde yürütüldü. Araştırma süresince, günlük ortalama canlı ağırlık artışı Hk, Hd, LxJk ve LxJd gruplarında sırasıyla 1.571, 1.462, 1.363 ve 1.412 kg olarak tespit edildi. Her kg canlı ağırlık artışı için tüketilen toplam kuru madde miktarları ise gruplarda sırasıyla 6.01, 6.46, 6.93 ve 6.69 kg olarak belirlendi.Araştırmanın 60. gününde alınan rumen sıvısı numunelerinde belirlenen pH, amonyak, toplam uçucu yağ asidi ve toplam tampon kapasitesi değerleri bakımından ırklar ve rasyon grupları arasında istatistiki açıdan herhangi bir farklılığa rastlanılmadı. Sonuç olarak, besi sığırı konsantre yemlerine 1 g/kg düzeyinde canlı maya kültürü katılmasının konsantre yeme dayalı besleme programında besi performansını ve rumen metabolitlerini etkilemediği gözlendi.
