the objective of this study was to evaluate the performance of male broiler chickens in the period from 21 to 42 days of age fed diets with increasing levels of sunflower meal (sm) supplemented with an enzyme complex (ec). a total of 1920 animals of the cobb strain were distributed in a randomized block design in a 4 × 3 factorial arrangement (four sm levels and three enzymes utilization types)...

This study was conducted to investigate the effects of commercial probiotic mixtures (Liptosafe-L) via drinking water of broiler chickens in comparison with Antibiotic (Newmycin) on performance of Broiler Chicks and growth attributes. 120 broiler chicks (Ross 308) day old, and average weight of 41 grams, were subjected to a 41-day experimental period. The chick's were randomly divided into thre...

The present study was carried out to examine the effect of supplemental dietary valine in the starter diet of broilers (0-15 d of age) on performance, antibodyresponse to Newcastle disease virus vaccination and bone mineralization. The experiment was conducted using 300 Ross 308 male broilers. One-day-old chicks were randomly allotted to 3 groups; each group consisted of 5 replicate pens with 2...

There are many studies on the effects of probiotics on performance of broiler chickens, but none of them has evaluated the metabolizable energy (ME) equivalency values of probiotics. The aim of this study was to determine the metabolizable energy equivalency value of Bacillus subtilis spore and its potential for decreasing feed ME content and cost. One hundred seventy-six day-old male broilers ...

Aim: This study was planned to investigate the effect of sugar beet, neem leaf, linseed and coriander on growth parameters such as feed intake, body weight gain, feed conversion ratio (FCR), performance index (PI), and carcass characteristics in broiler birds. Materials and Methods: The experiment was conducted for a period of 42 days on Vanaraja strain of broiler birds. Different dietary suppl...

AIM The risk of bacteria resistance to specific antibiotics possibly by continuous subtherapeutical administration of antibiotic growth promoters (AGPs) in poultry feed led to a ban on the use of AGP in poultry production. As a result of this ban, alternative substances for poultry growth promotion and disease prevention are being investigated, among which phytogenic and herbal products have re...

The present study was aimed to assess the influence of brown marine algae and vitamin E (VE) (160 ppm α-tocopheryl acetate) on stability of chicken meat enriched with fish oil. In this study, 360 d-old broilers (Arbor Acres Plus) were randomly assigned to 6 treatment groups with 4 replicates of 15 birds in each. Experimental groups consisted of corn-soybean basal diet (C), corn-soybean basal di...
