Performance of broiler chickens fed diets supplemented with a direct-fed microbial.
From hatch to 18 d of age broilers were fed starter diets with (0.9 kg/ton) or without direct fed microbial (DFM). At 18 d, birds were weighed and, within DFM treatment (trt), randomly assigned to battery pens. In Exp 1, a 2 x 2 factorial arrangement of nutrient density [control (C, 19.3% protein (CP), 0.84%, Ca 0.37% nonphytin P (nPP); and 17.1% CP, 0.8% Ca, and 0.3% nPP in the grower (Gr) and...
متن کاملStress Indicators to Pre-Slaughter Transportation of Broiler Chickens Fed Diets Supplemented with a Synbiotic
There is a growing interest concerning the welfare problems associated with harvesting, transportation and pre-slaughter handling of broilers. Transportation is a multifactor process associated with a variety of stressors which may covertly reduce welfare. Plasma corticosterone is elevated following a road which is consistent with the post-transport increase of heterophil: lymphocyte ratios (H/...
متن کاملIntestinal Development and Function of Broiler Chickens on Diets Supplemented with Clinoptilolite
The purpose of this study was to evaluate the effect of natural clinoptilolite (NCLI) and modified clinoptilolite (MCLI) on broiler performance, gut morphology, intestinal length and weight, and gut digestive enzyme activity. A total of 240 d-old male chicks were randomly assigned to 3 treatments, each of which comprised 8 pens of 10 chicks per pen. Birds in the control group were fed the basal...
متن کاملGrowth performance and digestive processes in broiler chickens fed diets supplemented with xylanase and fructooligosaccharides
Objective: The effect of xylanase and fructooligosaccharides on broiler chickens body weight, feed conversion (kg feed/kg weight), caecal volatile fatty acids (VFA) concentration and glycolytic enzymes activity was investigated. Methods: Six hundred birds were divided into three groups and for 35 days were fed basal diet (control) and diets contained 0.1% xylanase and 2% fructooligosaccharides ...
متن کاملGrowth performance and immune response of broiler chickens fed diets supplemented with probiotic and (or) prebiotic preparations
The objective of this research was to investigate the efficacy of dietary inclusion of probiotics Primalac® and Bactocell® and prebiotic Fermacto® on broiler’s performance and immune response, individually or in combination. A total of 540 one-d-old male Ross 308 broiler chicks were allocated into 6 experimental treatments with 6 replicates of 15 birds per replicate from 1 to 42 d of age. The b...
