Broyler rasyonlarına humat ile bitki ekstraktı karışımı ilavesinin büyüme performansı, bazı bağışıklık ve serum biyokimya değerlerine etkileri

Bu araştırma, broyler rasyonlarına doğal yem katkı maddesi olarak katılan humat ve bitki ekstrakt karışımının; büyüme performansı ile bir takım iç organ ve bağırsak parametrelerine ve serumda bazı immunolojik, biyokimyasal parametreler üzerine etkilerini belirlemek amacı ile gerçekleştirilmiştir. Araştırmada her biri kendi içersinde dört alt gruba sahip toplamda dört ana grubun olduğu deneme grupları oluşturulmuş ve her bir alt grupta 16 hayvan olmak üzere çalışmanın tamamında 256 adet günlük erkek broyler (Ross-308) kullanılmıştır. Deneme 1 kontrol ve 3 deneme grubu (1.5 g/kg humat, 0.75 g/kg bitki ekstrakt karışımı ve 1.5 g/kg humat ile 0.5 g/kg bitki ekstrakt karışımı beraber ilavesi) şeklinde gerçekleştirilmiştir. Denemenin sonunda rasyona adı geçen yem katkı maddelerinin ayrı ve bir arada ilave edilmesi, incelenen değerler açısından istatistiksel önemlilik göstermemiştir (P>0.05). İncelenen parametreler içersinde sadece kan serumunda belirlenen total protein düzeyleri gruplar arasında farklılıklar göstermiştir (P

Effects of humate and vegetable extract mixture supplementation to diets on growth performance, some immunity and serum biochemistry parameters in broiler chickens

This study has been conducted to determine the effects of humate and vegetable extract mixture supplementation to diets on body weight, body weight gain, feed intake, feed conversion ratio, hot carcass weight and yield, some organ weights, intestinal length, weight and pH, some immunological and blood parameters in broiler chickens. Totally 256 one-day old male broiler (Ross-308) chicks were divided into four treatment groups each of them also divided into four subgroups which contains 16 chicks for each in this trail. The experiment carried out one control and 3 treatments (1.5 g/kg humate supplementation, 0.75 g/kg vegetable extract mixture supplementation and 1.5 g/kg humate plus 0.75 vegetable extract mixture combination supplemented). At the end of trail, supplementation of these feed additives has been showed no statistically significant differences among all the treatment groups for performance and slaughter parameters (P>0.05). There was found only one statistically significant difference among the groups for blood total protein levels (P<0.01). Supplementation of vegetable extract mixture or combination with humate were decreased the levels of total protein in blood. As a result, we concluded that these feed additives had no beneficial effects on broiler performance which fed with high quality and balanced rations and reared out of stress conditions.
