1. Performance Parameters, Plasma Lipid Status, and Lymphoid Tissue Fatty Acid Profile of Broiler Chicks Fed Camelina Cake
ABSTRACT The effects of dietary camelina cake (CAMC) on broiler chicks’growth performance, plasma lipid status and fatty acid profile (FA) of lymphoid organs were evaluated. Six hundred broilers (3-week-old, Cobb 500) were randomly allotted for 20 days in a feeding trials into 2 groups: control (C; corn-soybean meal-canola meal basal diet) and experimental

2. Hematology and Histopathology of Broiler Chickens Supplemented with Tuna Black Flour
ABSTRACT The present study evaluated the effect of the sex and dietary intake of tuna black flour (TBF)on the hematology and histopathology of broiler chickens. A total of 200 sexed broilers (Ross 380) were distributed according to a completely randomized design into four treatments (25 males and 25 females/experimental group).Different levels of inclusion o

3. Effects of Dietary Supplementation with Red Algae Powder (Chondrus crispus) on Growth Performance, Carcass Traits, Lymphoid Organ Weights and Intestinal pH in Broilers
ABSTRACT The aim of this study was to determine the effects of dietary supplementation with red algae powder (Chondrus crispus) on the growth performance, carcass traits, lymphoid organ weights and intestinal pH y in broiler chickens. A total of 300 1-day-old B34 line male broiler chickens were randomly allotted to three treatments, four replicates per treat

4. Effect of different sources of selenium on performance and characteristics of immune system of broiler chickens
ABSTRACT An experiment was conducted based on a completely randomized design with 500 Ross 308 broiler chickens to investigate the effect of three different sources of selenium on performance and characteristics of immune system. Chickens were arranged in 10 treatments and five repetitions (10 chickens for each repetition). Ten treatments of experimental die

5. Oxidative Stress of in-Ovo Ochratoxin A Administered during Chick Embryonic Development
ABSTRACT The present work was carried out to study the effect of in-ovo injection of ochratoxin A (OTA) as an oxidative stress and its consequences on hepatic and kidney functions, thyroid activity, and histological examination of brain and liver in chicken embryos and subsequently in the hatching chicks. On the 10th day of incubation, one hundred and sixty-

6. Optimization of solid-state fermentation conditions of Bacillus licheniformis and its effects on Clostridium perfringens-induced necrotic enteritis in broilers
ABSTRACT In the present study, we examined the growth parameters of Bacillus licheniformis in solid-state fermentation (SSF) and evaluated the effects of Bacillus licheniformis-fermented products on Clostridium perfringens-challenged broilers. During four and six days of SSF, the highest viable biomass was observed at 5% glucose, 10% soybean meal, 3% yeast,

7. Distribution of Ifitm3 in Yellow-Feathered Broilers and Inhibition of Avian Reovirus Multiplication by Ifitm3
ABSTRACT This study was carried to express the interferon-induced transmembrane protein 3 (IFITM3) in vitro and examine its function in inhibition of avian reovirus (ARV) replication. The recombinant prokaryotic vector expressing yellow-feathered broiler IFITM3 was successfully constructed, and the recombinant protein was expressed in competent Escherichia c

8. The Gene Ontology Differs in Bursa of Fabricius Between Two Breeds of Ducks Post Hatching by Enriching the Differentially Expressed Genes
ABSTRACT The bursa of Fabricius (BF) is the central humoral immune organ unique to birds. The present study investigated the possible difference on a molecular level between two duck breeds. The digital gene expression profiling (DGE) technology was used to enrich the differentially expressed genes (DEGs) in BF between the Jianchang and Nonghua-P strains of

9. Effect of breeder age and storage conditions of Japanese quail eggs on hatchability, quail neonate quality, and Bursa of Fabricius characteristics
ABSTRACT Two experiments were conducted to evaluate combinations of different storage periods and temperature of hatching eggs of breeder quails in two stages of the production cycle (24 and 43 weeks) on hatchability, quail neonate quality, and Bursa of Fabricius characteristics. In each experiment, a total of 1.050 Japanese quail eggs were incubated in a ra

10. The Preventive Effects of Different Doses of Glucomannan on Experimental Aflatoxicosis in Japanese Quails
ABSTRACT This experimental study was performed to investigate whether there is a protective effect of different doses of Glucomannan using against aflatoxicosis in Japanese quail, and pathological changes and relative organ weights were compared. In the experiment, 60 one-day old male Japanese quails were used as divided into six different groups. Experiment

11. The effects of Environmental Enrichment on Some Physiological and Behavioral Parameters of Broiler Chicks
ABSTRACT This study aims to examine the effects of environmental enrichment (EE) practices on some physiological and behavioral parameters of broiler chicks. A total of 280 one-day old Ross 308 mixed-sex broiler chicks with an average initial body weight of 44.5±0.37 g were used in a 42-d trial. Broiler chicks were randomly allocated to 20 pens composed of

12. Feeding Programs for Broiler Breeders in the Start Phase
ABSTRACT The fast-growing Brazilian aviculture requires studies to improve zootechnical performance indexes for broiler breeders. The purpose of this study was to assess different feeding programs for broiler breeders on performance and development of digestive organs. A total of 48,000, 1d-old, Cobb 500 broiler breeders were divided into two sheds with 24,0
