“…Reduced growth performance and decreased enzyme activities have recently been reported in carp fed diets with exogenous enzymes above the optimal level (Jiang et al 2014). Poor weight gain was also reported in broiler chickens fed high levels of exogenous enzymes (Mendes, Ribeiro, Correia, Bule, Mac ßc ßãs, Falcão, Freire, Ferreira, Fontes & Lordelo 2013). Excess enzyme supplementation has been reported to result in osmotic diarrhoea or poor performance in chickens (Schutte 1990).…”

The effect of exogenous enzyme supplementation on growth performance and digestive enzyme activities inOreochromis mossambicusfed kikuyu-based diets

The utilization of plant‐based diets in fish is limited by the presence of anti‐nutrients, which bind to dietary nutrients and reduce their bioavailability. Exogenous enzyme supplementation may alleviate the effects of anti‐nutrients and improve feed utilization. In this study, a commercial multi‐enzyme Natuzyme50® was added to a kikuyu‐based diet at a rate of 0 (control), 0.25, 0.5, 0.75 and 1.00 g kg−1 DM. Each diet was fed to triplicate groups of Oreochromis mossambicus for 60 days. All fish fed diets containing Natuzyme50® had higher (P < 0.05) growth performance compared with those fed the control diet. Fish fed the diet containing 0.50 g kg−1 had the best growth performance, highest protein digestibility and the highest levels of digestive enzyme activities. When Natuzyme50® was supplemented above 0.50 g kg−1 in the diet, growth performance and enzyme activities decreased. The improved growth performance observed with Natuzyme50® supplementation was attributed to the presence of enzymes such as cellulase, xylanase and phytase in the cocktail that are not naturally produced by fish. The presence of these enzymes released bound nutrients that would have not been available to the fish. Natuzyme50® supplementation also increased (P < 0.05) the activities of endogenous enzymes, improving the efficacy of the digestive process. The optimal dietary level of Natuzyme50® for optimal growth performance in O. mossambicus was 0.62 g kg−1 DM feed. Cost benefit analysis indicate that adding up to 0.5 g Natuzyme50® kg−1 in the diet results in higher profits as the increased growth attained offset the additional cost of Natuzyme50®.

“…Triticale and wheat have similar nutrient composition, such as resistance to hard agronomic conditions [2,3] . Triticale is known to have high amounts of soluble non-starch polysaccharides (NSPs) [1] . It is well known that NSPs initially increase digesta viscosity and then reduce digesta passage, feed intake (FI), nutrient digestion and absorption [4] , and also increases harmful microbial population [5] .…”

This study was conducted to investigate the effects of physical form of diet and dietary inclusion of enzyme and probiotic on growth performance, mucin2 gene expression, morphology of small intestine and intestinal Lactobacillus population of broiler chicks fed with triticale-based diets. Six hundred forty 1-d-old broiler chicks were arranged in 8 treatments with 4 replicates (n=20 chicks). This study was done based on a randomized block completely design in a 2×2×2 factorial arrangement with two levels of feed form (pellet and mash), two levels of probiotic (0 and 0.03% diet) and two levels of enzyme (0 and 0.05% diet). Birds fed with pelleted diet had higher weight gain at starter and grower (P<0.001) and also lower feed conversion ratio at starter (P<0.001) and grower periods (P<0.01) than those fed the mash diet. Birds fed with pelleted diets containing enzyme and probiotic consumed the most feed intake at starter period. Mucin2 gene expression was significantly higher in birds fed the pelleted diets containing enzyme or/and probiotic and mash diets containing probiotic than those fed other diets (P<0.01). Intestinal morphology and intestinal Lactobacillus population were not influenced by experimental treatments (P>0.05) Thus, physical form of diet plays important role in improving performance and gene expression in birds fed with triticale-based diets.

Altı yüz kırk adet 1 günlük broiler civciv 8 uygulama ve 4 tekrar olmak üzere kurgulanmıştır (n=20 civciv). Çalışma rastgele dizayn usulünde olmak üzere 2x2x2 faktöriyel düzende planlanmış ve iki yem formu (pelet ve püre), iki probiyotik dozu (0 ve %0.03) ve iki enzim dozu (0 ve %0.05) denenmiştir. Pelet ile beslenen civcivler püre ile beslenenler ile karşılaştırıldığında başlangıç ve büyüme periyotlarında daha yüksek ağırlık kazanımı gösterirken (P<0.001), başlangıç (P<0.001) ve büyüme (P<0.01) periyotlarında daha düşük yem konversiyon oranına sahipti. Enzim ve probiyotik içeren pelet yem ile beslenen civcivler başlangıç periyodunda en yüksek yem tüketimine sahipti. Musin2 gen ekspresyonu enzim ve/veya probiyotik içeren pelet yem ile beslenen civcivler ile probiyotik içeren püre yem ile beslenenlerde diğer yemlemelere göre anlamlı derecede daha yüksekti (P<0.01). Bağırsak morfolojisi ve bağırsak Lactobacillus popülasyonu deneme gruplarında fark göstermedi (P>0.05). Sonuç olarak, tritikale temelli diyet ile beslenen civcivlerde yemin fiz...
