Background Nutritional interventions with natural antioxidants can provide a pragmatic solution for modifying hens’ performance and maintaining oxidative stability of eggs during storage. Quercetin is the most abundant flavonoids with potent antioxidant and immune stimulant activities. The concept of incorporating of quercetin, as potent antioxidan...

Artemisia annua L. ( A. annua ), renowned for its medicinal properties, was investigated for its effects on broiler performance, biochemistry, antioxidant capacity, meat composition, and organ histology. A total of 90 one-day-old chicks were divided into four groups, each with three replicates. The chicks were fed either a basal diet or a basal die...

Background and Aim Artemisia annua (AA), used as a growth promoter in poultry, lowers feed costs and enhances economic efficiency. This study aimed to assess the impact of varying AA concentrations on broiler chicken growth, gene expression, and profitability. Materials and Methods Two hundred 1-day-old male Cobb chicks were randomly allocated int...

This study sheds the light on the potential of licorice (Glycyrrhiza glabra) root aqueous extract as a cornerstone for mitigating and detoxifying the residues of the widely used agricultural Glyphosate-based pesticides (GBPs). This study examined the GBPs toxic effects on kidney, liver, thyroid functions, and apoptosis using 50 adult male albino ra...

The immune and antioxidant genetic factors that could converse with mastitis susceptibility in dromedary camels were looked at in this research. Of 120 female dromedary camels (60 healthy, and 60 with mastitis) were utilised. Each camel’s jugular vein was pierced to obtain five millilitres of blood. The blood was placed within tubes containing sodi...

Simple Summary Future reproduction methods for boosting crucial traits will likely be influenced by the proportion of genetic and phenotypic variances. Using PCR-DNA sequencing, the variations in the nucleotide sequences of the immunological genes between healthy buffaloes and buffaloes suffering from inflammatory reproductive disorders were discov...

ARTICLE INFO ABSTRACT Keywords Dromedary milk has a proven outstanding history of being a nutrient-rich food. Camel milk possesses both medicinal and technological advantages, including antioxidant, antibacterial, and antiparasitic activities. The present investigation is proposed to assess the antibacterial ability and free radical scavenging capa...

A total of 636 1-day-old male Cobb chicks were randomly assigned to seven treatments. The chicks were offered feed and water ad libitum throughout the experimental period. The first three groups included different stocking densities of broiler birds (low stocking density, LSD: 23 kg/m²; medium stocking density, MSD: 34 kg birds/m²; and high stockin...

A total of 636 one-day-old Cobb chicks were randomly assigned to seven treatments. The chicks were offered feed and water ad libitum throughout the experimental period. The first three groups included different stocking densities of broiler birds (low stocking density, LSD: 10 birds/m ² ; medium stocking density, MSD: 15 birds/m ² ; and high stocki...

Simple Summary Poultry breeding programs are established to ameliorate the genetic potential of domestic birds through a selection process and crossbreeding programs. In this context, crossbreeding has been considered as an essential tool to produce favorable genotypes, which are affected by different genetic resources and non-genetic factors. Thus...

Four hundred and eighty 1-day-old Japanese quail chicks from white and brown strains, 240 birds from each strain, were divided into 4 treatment groups with 6 replicates each (10 birds/replicate). Both strains of quail were fed diets containing 0%, 3%, 6%, and 9% pomegranate peel (PP) powder for a period of 42 days. Results revealed that the final b...

The current experiment was designed to study the response of two strains of laying Japanese quail to diet containing different levels (0%, 3%, 6%, and 9%) of pomegranate peel (PP) powder for a period of 6 weeks, on egg production, blood chemistry, carcass traits, expression of FSHR and LH-β genes, and economic efficiency. A total of 576 6-week-old...

Aim: This study aimed to investigate the underlying mechanism by which myostatin (MSTN) inhibitor MSTNpropeptide (MSTNP) could regulate the expression of some muscle growth-related genes, Pax3, Pax7, MyoD and MyoG in chick embryo. Materials and methods: The pre-somitic mesoderm (PSM) of HH7 Fayoumi chick embryos (n = 100) were injected with either...

7. Summary This work was carried out in Department Of Physiology, Faculty of Veterinary Medicine, (Moshtohor), Benha University during period from March 2012- March 2013. The aim of this work was to investigate the effect of supplementation of prebiotic (Bio-Mos®) to one day old chick Japanese quail till the end of experiment (56 days)on the follow...

The objective of the current study was to evaluate the effects of a commercial prebiotic (Bio-Mos®) feed additive as a growth promoter on growth performance and some growth-related hormones of Japanesequail. A total number of 480 one day old Japanese quail chicks were randomly allocated into 4 equal groups. Group 1(control group) fed on the basal d...

A B S T R A C T Pneumogen-5 vaccine, an inactivated polyvalent vaccine (BVD-genotypes 1 and 2, IBR, PI-3, and BRS viruses), was prepared for control of respiratory diseases producing great losses to calves. It was tested for quality and then applied in pregnant cattle 8 weeks before calving for evaluation of their humeral immune response under fiel...
