Cassava residues in the diet of slow-growing broilers

چکیده

ABSTRACT Cassava by-products are abundant and largely unused in familiy agro-industries the Amazon region, where slow-growing broilers commonly raised. Thus incorporation of cassava broiler feed may provide starch enrichment for better zootechnical performance. We evaluated use residues instead corn diet broilers. determined chemical composition scrapings (CS) residue (CSR), tested digestibility 192 three treatments: inclusion 30 g kg-1 CS or CSR a control without residue, with eight replicates each. Digestibility was assessed through collection total excreta from 19 to 22 days age. Apparent corrected metabolizable energy, apparent coefficients dry matter, crude protein energy were significantly higher than CS. Therefore, only used performance experiment using 324 90 old, distributed four treatments (0; 6.8; 13.4 20 feed) nine There no significant difference among weight gain, intake, yield carcass, breast viscera, meat color, luminosity, pH, shear force, cooking-weight loss drip loss. As there reduction conversion thigh drumstick kg-1, we suggest up kg-1.

Deep Sequencing Analysis of miRNA Expression in Breast Muscle of Fast-Growing and Slow-Growing Broilers

Growth performance is an important economic trait in chicken. MicroRNAs (miRNAs) have been shown to play important roles in various biological processes, but their functions in chicken growth are not yet clear. To investigate the function of miRNAs in chicken growth, breast muscle tissues of the two-tail samples (highest and lowest body weight) from Recessive White Rock (WRR) and Xinghua Chicke...

Comparison of the Genome-Wide DNA Methylation Profiles between Fast-Growing and Slow-Growing Broilers

INTRODUCTION Growth traits are important in poultry production, however, little is known for its regulatory mechanism at epigenetic level. Therefore, in this study, we aim to compare DNA methylation profiles between fast- and slow-growing broilers in order to identify candidate genes for chicken growth. Methylated DNA immunoprecipitation-sequencing (MeDIP-seq) was used to investigate the genome...

Residues of dioxins and PCBs in fat of growing pigs and broilers fed contaminated feed.

To investigate the kinetics of PCBs and dioxins, 3 week old broilers and 3 month old pigs were fed with a 10-fold diluted feed from the Belgium crisis for one week, followed by a period on clean feed. In the case of broilers this resulted in levels for dioxins, non-ortho and mono-ortho PCBs in fat of 102, 84 and 216 ng TEQ/kg, summarized to 402 ng TEQ/kg. Total levels decreased to 217 and 109 n...
