Abstract

Amaç: Bu çalışmada, kesim öncesi 6 ve 12 s’lik açlık periyodu boyunca içme suyuna ticari organik asit karışımı (OAK) ilavesinin erkek piliçlerin kesim özellikleri, et kalitesi, bazı kan parametreleri ve ince bağırsak Salmonella spp. ve Coliform popülasyonları üzerine etkileri incelenmiştir.
Materyal ve Yöntem: Çalışmada 42 günlük yaşta 28 adet erkek etlik piliç (Ross-308) kullanılmıştır. Hayvanlar rastgele 4 muamale grubuna ayrılmıştır. Bunlar; K 6 s: piliçlere 6 s’lik açlık periyodunda içme suyu verilmiştir, K 12 s: piliçlere 12 s’lik açlık periyodunda içme suyu verilmiştir, OAK 6 s: piliçlere 6 s’lik açlık periyodunda OAK ilaveli içme suyu verilmiştir ve OAK 12 s: piliçlere 12 s’lik açlık periyodunda OAK ilaveli içme suyu verilmiştir.
Bulgular: Kesim öncesi açlık periyodunun 6 s’ten 12 s’e uzatılması karkas randımanını, T3 düzeyini, bezel mide ve taşlık pH’larını azaltmış, buna karşın bağırsak Coliform bakteri sayısını arttırmıştır (P<0,05). Erkek piliçlerde, kesim öncesi farklı açlık periyodlarında suya OAK ilavesi karkas, göğüs ve but ağırlıkları ile karkas ve göğüs randımnalarını olumsuz etkilemiş, buna karşın taşlık oransal değerini ve serum glukoz düzeyini artırmıştır (P<0,05).
Sonuç: Kesim öncesi açlık süresi uzadıkça içme suyana OAK ilavesi bağırsak Coliform popülasyonunu arttırmıştır.

The Effects of Pre-slaughter Feed Withdrawal Period and Organic Acid Supplementation into Drinking Water on Slaughter Yield, Meat Quality, Intestinal Microflora and Some Blood Traits in Broiler

Abstract

Objective: In this study, it was investigated the effects of commercial organic acid mixture supplementation (OAM) into drinking water during the 6 and 12 h pre-slaughter fasting period on slaughter traits, meat quality, some blood parameters and small intestine Salmonella spp. and Coliform populations of male broilers.
Material and Methods: In the study, 28 male broilers (Ross-308) at 42 days of age were used. Animals were randomly divided into 4 treatment groups. These are follows; C 6 h: birds were given drinking water during the 6 h fasting period, C 12 h: birds were given drinking water during the 12 h fasting period, OAM 6 h: birds were given drinking water with OAM during the 6 h fasting period, and OAM 12 h: birds were given drinking water with OAM during the 12 h fasting period.
Results:The extension of the pre-slaughter fasting period from 6 h to 12 h decreased carcass yield, T3 level and the pH values of proventriculus and gizzard, but increased intestinal Coliform bacteria count (p<0,05). In male broilers, OAM supplementation into the drinking water during different pre-slaughter fasting periods adversely affected carcass, breast and thigh weights and carcass and breast yields, yet increased the gizzard proportional value and serum glucose level (p<0,05).
Conclusion: As the pre-slaughter fasting period extends, the addition of OAM to the drinking water increased the intestinal Coliform population.
