The Effect of Total Mixed Fermentation on Fattening Performance of Brangus Bulls Imported from Brasil

Abstract

The aim of this study is to investigate the effects of total mixed ration (Control, C), fermented total mixed ration (Control Fermented, CF) and fermented fattening feed prepared with by-products (By-product Fermented, BF) on fattening performance in Brangus male bulls. In the research, a total of 114 Brangus fattening bulls were used and divided into 3 main groups and 5 subgroups were formed under each main group. All bulls were weighed at the beginning of fattening and then monthly, dry matter consumption, daily live weight gains and feed conversion ratios were calculated. There was no statistical difference between the groups in the initial and final body weights of the animals (P>0.05). The average daily gain of the bulls were determined in the band of approximately 1.50 kg and no statistical difference was found between the groups (P>0.05). On the other hand, dry matter intake was determined as 10.68, 11.66 and 10.64 kg/day in the C, CF and BF groups, respectively, and a trend was found between the groups (P=0.08). Likewise, feed conversion ratios were determined as 6.93, 7.52 and 7.09 in the CK, CF and BF groups, respectively, and a trend was found between the groups (P=0.08). On the other hand, bulls fed with BF group; The group fed with K can reach the same body weight on the same days and are fed 2.81 TL cheaper per animal per day. It can be concluded that if by-products are fermented and given to Brangus beef cattle, there is no difference in fattening performance compared to other groups, but it provides great economic benefits.

Brezilya’dan İthal Edilen Brangus Irkı Besi Danalarında Fermente Toplam Karma Rasyon Kullanımının Besi Performansı Üzerine Etkisi

Abstract

Bu araştırmanın amacı; toplam karma rasyon (Kontrol, K), fermente olmuş toplam karma rasyon (Kontrol Fermente, KF) ve yan ürünlerle hazırlanmış fermente besi yeminin (Yan ürün Fermente, YF) Brangus ırkı erkek danalarında besi performansı üzerindeki etkilerini incelemektir. Araştırmada toplam 114 Brangus ırkı besi danası kullanılmış ve 3 ana gruba ayrılmış ve her bir ana grubun altında 5 adet alt grup oluşturulmuştur. Bütün danalar besi başlangıcında ve daha sonra aylık olarak tartılmış, kuru madde tüketimleri, günlük canlı ağırlık artışları ve yemden yararlanma oranları hesaplanmıştır. Hayvanların başlangıç ve bitiş canlı ağırlıklarında gruplar arasında istatistiki bir farklılık saptanmamıştır (P>0.05). Danaların günlük canlı ağırlık artışları yaklaşık 1.50 kg bandında tespit edilmiş ve gruplar arasında istatistiki bir fark bulunmamıştır (P>0.05). Diğer taraftan günlük kuru madde tüketimlerinde ise K, KF ve YF gruplarında sırasıyla 10.68, 11.66 ve 10.64 kg/gün olarak tespit edilmiş olup gruplar arasında bir eğilim saptanmıştır (P=0.08). Aynı şekilde yemden yararlanma oranlarında da K, KF ve YF gruplarında sırasıyla 6.93, 7.52 ve 7.09 olarak tespit edilmiş olup gruplara arasında bir eğilim saptanmıştır (P=0.08). Diğer yandan YF grubu ile beslenen danalar; K ile beslenen gruba göre aynı canlı ağırlığa aynı günlerde ulaşabilmekte ve günlük hayvan başına 2.81 TL daha ucuza beslenmektedirler. Sonuç olarak bu araştırmadan; yan ürünlerin fermente edilip Brangus besi danalarına verilmesi durumunda besi performansında diğer gruplara göre farklılık yaratmadığı ancak ekonomik olarak büyük fayda sağladığı sonucu çıkarılabilmektedir.
