Kuzularda Diyetle Verilen Protein ve Tanen Düzeyinin Besi Performansı, Rumen Uçucu Yağ Asidi Profili ve Metan Üretimi Üzerine Etkisi
Abstract
Bu çalışmanın amacı, etçi tip kuzularda iki farklı protein düzeyi ( %14 ve %18) ile iki farklı tanen düzeyini ( %0 ve %4) test etmektir. Toplam 36 Çukurova Etçi Tip kuzu (3/8 Rambouillet, 3/8 Île‑de‑France, 1/8 Awassi, 1/8 Sakız) 24,69 ± 0,87 kg canlı ağırlıkta başlangıç yapmış, her biri 9 erkek kuzudan oluşan 4 gruba ayrılmış ve her grupta 3 kuzudan oluşan 3 tekerrür bulunmuştur. Rasyonlar izokalorik olarak düzenlenmiştir. Her deneme yemi, %10 kıyılmış yonca otu ve %90 konsantre yem içeren toplam karışık rasyon şeklinde hazırlanmıştır. Günlük canlı ağırlık artışı ve yem dönüşüm oranları hiçbir faktörden etkilenmemiştir (P > 0,05), ancak yem tüketimi protein düzeyi ile protein × tanen düzeyi etkileşiminden etkilenmiştir (P < 0,01). Rumen sıvısında asetik ve propiyonik asitler üzerinde faktörlerin anlamlı etkisi görülmemiştir (P > 0,05). Buna karşılık bütirik ve valerik asitler, diyetin tanen düzeyi ile protein × tanen düzeyi etkileşiminden etkilenmiştir (P < 0,05). İzobütirik asit hem ana faktörlerden hem de etkileşimlerinden etkilenmiştir (P < 0,05). Protein düzeyindeki artış izobütirik asit miktarını artırırken, diyete tanen ilavesi izobütirik asit düzeyini düşürmüştür; bu azalma yüksek proteinli diyette daha belirgin, düşük proteinli diyette ise daha hafif olmuştur. Rumen sıvısındaki izovalerik asit, diyet protein düzeyinden etkilenmiştir (P < 0,001); yüksek proteinli diyet alan kuzularda konsantrasyon daha yüksek bulunmuştur (0,32 mmol/L’ye karşı 0,67 mmol/L). 24 saatlik toplam gaz üretimi protein × tanen düzeyi etkileşiminden, 24 saatlik metan üretimi ise tüm faktörlerden etkilenmiştir (P < 0,05). Tanen, düşük proteinli diyette toplam gaz üretimini azaltmış, ancak yüksek proteinli diyette artırmıştır. Benzer şekilde, tanen düşük proteinli diyette 24 saatlik metan üretimini değiştirmezken, yüksek proteinli diyette artırmıştır. Sonuç olarak, başlangıç canlı ağırlığı 25 kg olan kuzular, diyet protein düzeyinin artırılmasından ve diyette tanen kullanımından fayda görmemiştir. Bununla birlikte, izoasit üretimleri değerlendirildiğinde tanen, protein yıkımını azaltmıştır.

The effect of dietary protein and tannin level on fattening performance, rumen volatile fatty acid profile and methane production in lambs
Abstract
The aim of this study was to test 2 protein levels (14% and 18%) and 2 tannin levels (0 and 4%) in fattening meat type lambs. 36 Çukurova Meat Type lambs (3/8 Rambouillet, 3/8 Ile de France, 1/8 Awassi, 1/8 Chios) having 24.69±0.87 kg initial live weight divided into 4 groups having 9 male lambs with 3 replicate consisting 3 lambs in each. Diets were formulated isocaloric. Total mixed diets were prepared containing 10% chopped alfalfa hay and 90% concentrate for each treatment. Daily gain, and feed conversion ratios were not affected by any factors (P>0.05), but feed intake was affected by protein level and protein level x tannin level interaction (P<0.01). It was investigated that factors did not affect asetic and propionic acids in rumen fluid significantly (P>0.05). However butyric and valeric acids were affected by tannin level in the diet and protein x tannin level interaction (P<0.05). Isobutyric acid was affected by both main factors and their interactions (P<0.05) While increase in protein level resulted an increase in isobutyric acid, tannin usage in the diet decreased isobutyric acid in rumen fluid. Severity of decrease in isobutyric acid in rumen fluid by using tannin in high protein diet was higher but it was lower in low protein diet. Isovaleric acid in rumen fluid was affected by dietary protein level (P<0.00) and the lambs receiving high protein diet had higher concentration (0.32 vs. 0.67 mmol/L) than those receiving low protein diet. While 24 hour total gas production was affected by protein x tannin level interaction, 24 hour methane production was affected by all factors (P<0.05). Tannin with low protein reduced total gas production, but increased in the diet having high protein. Similarly tannin did not changed 24 hour methane production with the diet low protein but increased in the diet with high protein. In conclusion, the lamb having 25 kg initial body weight was not benefited from increase in protein level in the diet and tannin usage in the diet. However tannin decreased protein degradation when the isoacids production was evaluated.
