Karma Yeme İlave Edilen Probiyotik, Prebiyotik ve Enzim Karışımının Etlik Piliçlerde Performans, Karkas, Organlar, İleal pH ve Viskozitesi Üzerine Etkileri

Abstract

Objective:The experiment was conducted to determine the individual and combined effects of probiotic, prebiotic and enzyme on performance, carcase, organs, intestinal pH and viscosity of broilers. Material and Methods: A total of seven hundred day-old male Ross-308 broiler chicks were individually weighted and distributed into 28 floor pens with 25 chicks per pen in from 0 to 42 d of age. Seven starter and grower diets were formulated to provide a similar nutrient profile with the exception of using experimental feed additives (1 g per kg) or a combined addition of these additives (0.5 g+0.5 g per kg). The diets were supplemented with: no feed additives (control), probiotic, prebiotic, enzyme, probiotic+prebiotic, probiotic+enzyme mixture, prebiotic+enzyme mixture. Results: Probiotic, probiotic+prebiotic and probiotic+enzyme supplementation significantly increased body weights at 42 days (P<0.05). There were no differences in feed intake, feed conversion ratio, relative weights of the proventriculus, gizzard, duodenum, jejunum, ileum, colon, cecum liver, pancreas, spleen, heart and bursa of broilers among the treatments during the experiment (P>0.05). Intestinal pH and viscosity were decreased by adding feed additives when compared with the control. Conclusion: The synergistic effects between probiotics, prebiotics and enzymes should be further investigated, and suitable combinations and levels should be determined in practice. ÖZAmaç: Deneme, probiyotik, prebiyotik ve enzimin etlik piliçlerde performans, karkas, organlar, bağırsak pH'ı ve viskozitesi üzerine tek başına ve kombine etkilerini belirlemek amacıyla yürütülmüştür. Materyal ve Metot: Bir günlük yaşta 700 adet erkek Ross-308 etlik civciv, bireysel olarak tartılmış ve her bölmede 25 civciv olacak şekilde 28 gruba dağıtılarak 0-42. günler arasında barındırılmıştır. Denemede kullanılan katkı maddeleri dışında benzer besin madde profiline sahip ve kullanılan yem katkı maddesinin tek başına (1 g/kg) veya kombine şekilde (0.5 g/kg+0.5 g/kg) ilave edildiği yedi adet başlatma ve büyütme yemi formülasyonu oluşturulmuştur. Yemler, katkı maddesi içermeyen (kontrol), prebiyotik, enzim, probiyotik+prebiyotik, probiyotik+enzim ve prebiyotik+enzim içerecek şekilde hazırlanmıştır. Bulgular: Probiyotik, probiyotik+prebiyotik ve probiyotik+enzim ilavesi 42. gün canlı ağırlığını önemli derecede artırmıştır (P<0.05). Deneme süresince, gruplar arasında yem tüketimleri, yemden yararlanma oranları ile bezel mide, taşlık, duedonum, jejunum, ileum, kalın bağırsak, kör bağırsak, karaciğer, pancreas, dalak, kalp ve bursanın oransal ağırlıkları bakımından bir farklılık saptanmamıştır (P>0.05). Yem katkısı ilavesinin bağırsak pH'ı ve viskozitesi üzerine önemli bir etkisi belirlenmiştir. Kontrol grubu ile karşılaştırıldığında deneme katkılarının ilavesi ile bağırsak pH'ı ve viskozitesi azalmıştır. Sonuç: Probiyotikler, prebiyotikler ve enzimler arasındaki sinerjik etkiler daha fazla araştırılmalı, pratikte uygun kombinasyonlar ve seviyeler belirlenmelidir.

Blood and Intestine Profile of Broilers Fed Averrhoa bilimbi Fruit, Wheat Bran, and Yeast Blends

“…In another study conducted, the effect of probiotic and enzyme addition on mixed feed was found to be significant on ileal pH. The highest ileal pH was found in the control group (Kırkpınar et al, 2018). The excessive buffering action of ileum was not observed in broilers, given either 0.5% or 1.0% of the additive in the current study.…”

Synergistic effect of probiotic, chicory root powder and coriander seed powder on growth performance, antioxidant activity and gut health of broiler chickens

“…(2009) [ 27 ], who reported supplementation of probiotic and prebiotic combination improved the final body weight of broilers at 42 d of age. Similarly, supplementation of probiotic + prebiotic and probiotic + enzyme combination increased the body weight of broilers compared to control at 42 d of age [ 9 ]. Barad et al .…”

“…The fermentation activity of inulin inhibits the growth of harmful strains, selectively stimulates the growth of beneficial bacteria by decreasing the intestinal pH through increasing the absorption of short chain fatty acids and thus promotes the growth of broiler chickens [ 7 , 8 ]. Similarly, probiotic + prebiotic supplementation decreased intestinal pH and viscosity in broilers [ 9 ]. Addition of probiotics ( Lactobacillus acidophilus and lactose fermenting enterobacteria) and prebiotic combinations in broilers significantly (P<0.05) increased the villus height and crypt depth of the duodenum, ileum and jejunum [ 10 ].…”

Effect of novel natural feed additive containing Averrhoa bilimbi L. fruit filtrate, wheat bran, and Saccharomyces cerevisiae on growth performance and meat characteristics of broilers

“…A previous study reported that using acidifiers and probiotics in combination had a greater impact on broiler production and health than using an acidifier and probiotic separately [ 2 ]. In addition, several studies have reported that combining probiotics with prebiotics increased probiotic efficacy compared with using probiotics alone [ 6 , 7 ]. Wheat bran has been identified as a prebiotic-rich and affordable feed ingredient for broiler chickens [ 8 ].…”
