Özet
Bu çalışmada, farklı protein kaynağı içeren konsantre yemlerin 30, 60 ve 90 günlük besi sürelerinde tuj kuzularının canlı ağırlık artışı, yem tüketimi ve yemden yararlanma oranı üzerine etkisi incelenerek, maliyet-fayda analizi yapıldı. Denemede materyal olarak 33.5 aylık yaşta sütten kesilmiş 24 baş Tuj ırkı erkek kuzu kullanıldı. Rasgele seçilen, 6 baş kuzu içeren 4 ayrı deneme grubu oluşturuldu ve gruplara aynı enerji-protein düzeyinde farklı protein kaynakları içeren konsantre yem karmaları hazırlandı. Kaba yem olarak çayır kuru otu kullanıldı. Alıştırma döneminin ardından, 30, 60 ve 90 günlük dönemler sonunda kuzuların yem tüketimi, canlı ağırlık artışları ve yemden yararlanma oranları belirlendi. 0-30 günlük dönemde toplam yem tüketimi (kg), canlı ağırlık artışı (kg) ve yemden yararlanma oranı (kg/kg) sırasıyla 32.29±1.74, 6.13±0.39 ve 5.43±0.18, 0-60 günlük dönemde sırasıyla 69.55±3.96, 11.66 ±0.78 ve 6.16±0.22, 0-90 günlük dönemde ise 110.22±5.63, 16.40±1.03 ve 6.92±0.22 olarak belirlendi. Dönemler arasında farkın önemli olduğu tespit edildi (P<0.001). Dört farklı bitkisel protein kaynağı içeren değişik konsantre yemle beslenen gruplarda 30, 60, 90 günlük dönemlerde yapılan maliyet ve gelir hesaplamaları sonucunda, işletme karlılığı bakımından 90 günlük besi süresinin uygulanabileceği ve protein kaynağı olarak ise ayçiçeği küspesinin rasyonlarda kullanılmasının daha uygun olabileceği kanısına varıldı.
In this study, live body weight increase, feed consumption and feed conversion rates as well as cost-benefit analysis were investigated in Tuj lambs fed with concentrate feed containing different protein sources for the feeding period of 30, 60 and 90 days. 24 weaning Tuj breed male lambs at 3-3.5 months of age were used as the animal material. The animals were randomly divided into 4 groups each consisting of 6 lambs, and each group was fed with concentrate feeds containing the same level of energy-protein from different protein sources. Meadow grass was used as roughage. After the acclimatization period, feed consumption, live body weight increase and feed conversion rates in the groups were determined at the end of 30-, 60- and 90-day periods. Total feed consumption, live body weight increase and feed conversion rates at 30-day period were 32.29±1.74, 6.13±0.39 and 5.43±0.18, at 60-day period were 69.55±3.96, 11.66±0.78 and 6.16±0.22, at 90-day period were 110.22±5.63, 16.40±1.03 and 6.92±0.22, respectively. Differences among periods were statistically significant (P<0.001). Among the groups fed with different concentrate feeds containing 4 different vegetative protein sources, results of cost analysis indicated that 90-day feeding and sunflower meal as the protein source should be utilized for the operational benefit.
